[PATCH] zr36067 driver - reduce stack size usage
Reduce local variable (large struct) stack usage in zoran_do_ioctl() from 1028
bytes to 324 bytes (on x86-32) by declaring & using only 1 "struct
zoran_jpg_settings" instead of 5 instances of it. Reduced from 5 * 180 bytes
to 1 * 180 bytes, plus other locals in each case.

[PATCH] zr36067 driver - ppc/be port
Attached patch adds some host<->le conversion functions for 32-bit integers.
The hardware expects 32-bit integers, which the host does not always provide.
With the attached patch, the hardware runs fine on PPC hardware as well.

[PATCH] zr36067 driver - correct jpeg app/com markers
Attached patch fixes the writing of APP (application-specific) and COM
(comment) markers in the JPEG stream as generated by the zr36050 or zr36060
encoders, both part of the zr36067 driver.
During separating those bits out of the main zoran driver, we accidently
removed the interface through which applications can adapt those markers,
replacing them by unchangeable (static) markers. Some video formats,
particularly Quicktime and AVI, require specific container-specific markers in
the stream for interlaced streams. Those markers specify field order and
such.
The attached patch re-adds this feature so that decoders depending on those
container-specific markers for correct playback will work correctly.

[PATCH] fix ROM enable/disable in r128 and radeon fb drivers
Both the r128 and radeon fb drivers do bad things with the PCI BAR
corresponding to their option ROM. They incorrectly use the host address
instead of the BAR address to enable the ROM, and then incorrectly lose the
original value on unmap. This patch fixes both problems. Tested on Altix.

[PATCH] pm2fb: fix big-endian (Sparc) support
A collection of changes that taken together makes the driver work correctly on
big-endian systems, specifically Sparc.
- Remove old PM2FB_BE_APERTURE define and use __BIG_ENDIAN
throughout. PM2FB_BE_APERTURE wasn't defined on Sparc; this
was incorrect.
- Replace colour mode magic numbers with suitable constants,
and tidy colour mode handling. Use BGR not RGB at 24bit on
big-endian.
- Replace aperture magic numbers with constants. Rearrange code to
emphasise second aperture is not used. Add short explanations
of aperture settings for big endian.
- Update comments to note that the driver now works on Sparc.
- Revisit 32bit depth colour offsets and ensure transp is set.

[PATCH] knfsd: nfsd_translate_wouldblocks
-EAGAIN has a special treatment in the nfsd code since it's used to indicate
that an upcall has been initiated and that a request should be dropped pending
the upcall result.
But when the break_lease functions return -EWOULDBLOCK (==-EAGAIN on most
architectures), we actually prefer to return nfserr_jukebox. So translate
-EAGAIN returns to -ETIMEDOUT (which will be translated to nfserr_jukebox).
Undo the mapping of -EWOULDBLOCK to nfserr_jukebox, since on most
architectures that has the undesireable effect of mapping -EAGAIN to
nfserr_jukebox.

This patch adds new permission checks to the SELinux mmap and mprotect hooks

The task->self execmem permission controls the ability to create an executable
anonymous mapping or a writable executable private file mapping. The
task->file execmod permission controls the ability to make executable a
previously written private file mapping, e.g. for text relocations. Thanks

[PATCH] SELinux: add dynamic context transition support to SELinux
This patch for adds dynamic context transition support to SELinux via writes
to the existing /proc/pid/attr/current interface.
Previously, SELinux only supported exec-based context transitions. This
functionality allows privileged applications to apply privilege bracketing
without necessarily being refactored to an exec-based model (although such a
model has advantages in least privilege and isolation).
A process must have setcurrent permission to use this mechanism at all, and
the dyntransition permission must be granted between the old and new security
contexts. Multi-threaded processes are not allowed to use this operation, as
it will yield an inconsistency among the security contexts of the threads
sharing the same mm.
Ptrace permission is revalidated against the new context if the process is
being ptraced.

[PATCH] SELinux scalability: convert AVC to RCU
The following patch improves the scalability of SELinux by replacing the
global avc_lock with an RCU based scheme by Kaigai Kohei. The size of the
cache is made tunable, to allow administrators to tune systems for different
workloads, while statistics are exported via selinuxfs to allow AVC
performance to be monitored at a low level.
AVC nodes are also allocated now via a slab cache, and AVC references have
been removed from the code.
This code has been extensively tested and benchmarked (see benchmark results
below). Baseline performance is not improved, although it is clear that
dramatic scalability improvements are achieved.
Baseline performance and networking scalability are areas where work is
ongoing (in particular, we need to add caching of some network security
objects so that we don't fallback to policy database lookups on each
permission call).

[PATCH] task_struct.exit_state usage
I just did a quick audit of the use of exit_state and the EXIT_* bit
macros. I guess I didn't really review these changes very closely when you
did them originally. :-(
I found several places that seem like lossy cases of query-replace without
enough thought about the code. Linus has previously said the >= tests
ought to be & tests instead. But for exit_state, it can only ever be 0,
EXIT_DEAD, or EXIT_ZOMBIE--so a nonzero test is actually the same as
testing & (EXIT_DEAD|EXIT_ZOMBIE), and maybe its code is a tiny bit better.
The case like in choose_new_parent is just confusing, to have the
always-false test for EXIT_* bits in ->state there too.
The two cases in wants_signal and do_process_times are actual regressions
that will give us back old bugs in race conditions. These places had
s/TASK/EXIT/ but not s/state/exit_state/, and now there tests for exiting
tasks are now wrong and never catching them. I take it back: there is no
regression in wants_signal in practice I think, because of the PF_EXITING
test that makes the EXIT_* state checks superfluous anyway. So that is
just another cosmetic case of confusing code. But in do_process_times,
there is that SIGXCPU-while-exiting race condition back again.

[PATCH] move waitchld_exit from task_struct to signal_struct
There is really no point in each task_struct having its own waitchld_exit.
In the only use of it, the waitchld_exit of each thread in a group gets
woken up at the same time. So, there might as well just be one wait queue
for the whole thread group. This patch does that by moving the field from
task_struct to signal_struct. It should have no effect on the behavior,
but saves a little work and a little storage in the multithreaded case.

[PATCH] fix ptracer death race yielding bogus BUG_ON
There is a BUG_ON in ptrace_stop that hits if the thread is not ptraced.
However, there is no synchronization between a thread deciding to do a
ptrace stop and so going here, and its ptracer dying and so detaching from
it and clearing its ->ptrace field.
The RHEL3 2.4-based kernel has a backport of a slightly older version of
the 2.6 signals code, which has a different but equivalent BUG_ON. This
actually bit users in practice (when the debugger dies), but was
exceedingly difficult to reproduce in contrived circumstances. We moved
forward in RHEL3 just by removing the BUG_ON, and that fixed the real user
problems even though I was never able to reproduce the scenario myself.
So, to my knowledge this scenario has never actually been seen in practice
under 2.6. But it's plain to see from the code that it is indeed possible.
This patch removes that BUG_ON, but also goes further and tries to handle
this case more gracefully than simply avoiding the crash. By removing the
BUG_ON alone, it becomes possible for the real parent of a process to see
spurious SIGCHLD notifications intended for the debugger that has just
died, and have its child wind up stopped unexpectedly. This patch avoids
that possibility by detecting the case when we are about to do the ptrace
stop but our ptracer has gone away, and simply eliding that ptrace stop
altogether as if we hadn't been ptraced when we hit the interesting event
(signal or ptrace_notify call for syscall tracing or something like that).

[PATCH] fix stop signal race
The `sig_avoid_stop_race' checks fail to catch a related race scenario that
can happen. I don't think this has been seen in nature, but it could
happen in the same sorts of situations where the observed problems come up
that those checks work around. This patch takes a different approach to
catching this race condition. The new approach plugs the hole, and I think
is also cleaner.
The issue is a race between one CPU processing a stop signal while another
CPU processes a SIGCONT or SIGKILL. There is a window in stop-signal
processing where the siglock must be released. If a SIGCONT or SIGKILL
comes along here on another CPU, then the stop signal in the midst of being
processed needs to be discarded rather than having the stop take place
after the SIGCONT or SIGKILL has been generated. The existing workaround
checks for this case explicitly by looking for a pending SIGCONT or SIGKILL
after reacquiring the lock.
However, there is another problem related to the same race issue. In the
window where the processing of the stop signal has released the siglock,
the stop signal is not represented in the pending set any more, but it is
still "pending" and not "delivered" in POSIX terms. The SIGCONT coming in
this window is required to clear all pending stop signals. But, if a stop
signal has been dequeued but not yet processed, the SIGCONT generation will
fail to clear it (in handle_stop_signal). Likewise, a SIGKILL coming here
should prevent the stop processing and make the thread die immediately
instead. The `sig_avoid_stop_race' code checks for this by examining the
pending set to see if SIGCONT or SIGKILL is in it. But this fails to
handle the case where another CPU running another thread in the same
process has already dequeued the signal (so it no longer can be found in
the pending set). We must catch this as well, so that the same problems do
not arise when another thread on another CPU acted real fast.
I've fixed this dumping the `sig_avoid_stop_race' kludge in favor of a
little explicit bookkeeping. Now, dequeuing any stop signal sets a flag
saying that a pending stop signal has been taken on by some CPU since the
last time all pending stop signals were cleared due to SIGCONT/SIGKILL.
The processing of stop signals checks the flag after the window where it
released the lock, and abandons the signal the flag has been cleared. The
code that clears pending stop signals on SIGCONT generation also clears
this flag. The various places that are trying to ensure the process dies
quickly (SIGKILL or other unhandled signals) also clear the flag. I've
made this a general flags word in signal_struct, and replaced the
stop_state field with flag bits in this word.

[PATCH] __getblk_slow can loop forever when pages are partially mapped
When a block device is accessed via read/write, it is possible for some of
the buffers on a page to be mapped and others not. __getblk and friends
assume this can't happen, and can end up looping forever when pages have
some unmapped buffers. Picture:
lseek(/dev/xxx, 2048, SEEK_SET)
write(/dev/xxx, 2048 bytes)
Assuming the block size is 1k, page 0 has 4 buffers, two are mapped by
__block_prepare_write and two are not. Next, another process triggers
getblk(/dev/xxx, blocknr = 0);
__getblk_slow will loop forever. __find_get_block fails because the buffer
isn't mapped. grow_dev_page does nothing because there are buffers on the
page with the correct size. madhav@veritas.com and others at Veritas
tracked this down.
The fix below has two parts. First, it changes __find_get_block to avoid
the buffer_error warnings when it finds unmapped buffers on the page.
Second, it changes grow_dev_page to map the buffers on the page by calling
init_page_buffers. init_page_buffers is changed so we don't stomp on
uptodate bits for the buffers.

[PATCH] IRQ resource deallocation: ACPI
Architecture dependent IRQ resources such as interrupt vector for PCI
devices are allocated at pci_enable_device() time on i386, x86-64 and
ia64 platform. Today, however, these IRQ resources are never
deallocated even if they are no longer used. The following set of
patches adds supports to deallocate IRQ resources at
pci_disable_device() time.
The motivation of the set of patches is as follows:
- IRQ resources such as interrupt vectors should be freed if they
are no longer used because the amount of these resources are
limited. By deallocating IRQ resources, we can recycle them.
- I think some hardwares will support hot-pluggable I/O units with
I/O xAPICs in the near future. So I/O xAPIC hot-plug support by
OS will be needed soon. IRQ resouces deallocation will be one of
the most important stuff for I/O xAPIC hot-plug.
For now, the following set of patches has ia64 implementation only.
i386 and x86_64 implementations are TBD.
This patch is ACPI portion of IRQ deallocation. This patch defines the
following new interface. The implementation of this interface depends
on each platform.
o void acpi_unregister_gsi(u32 gsi)
This is a opposite portion of acpi_register_gsi(). This has a
responsibility for deallocating IRQ resources associated with
the specified GSI number.
We need to consider the case of shared interrupt. In the case
of shared interrupt, acpi_register_gsi() is called multiple
times for one gsi. That is, registrations and unregistrations
can be nested.
This function undoes the effect of one call to
acpi_register_gsi(). If this matches the last registration,
IRQ resources associated with the specified GSI number are
freed.
This patch also adds the following new function.
o void acpi_pci_irq_disable (struct pci_dev *dev)
This function is a opposite portion of
acpi_pci_enable_irq(). It clears the device's linux IRQ number
and calls acpi_unregister_gsi() to deallocate IRQ resources.

[PATCH] make gconfig work with gtk-2.4
I need this to make gconfig work under gtk-2.4. Without this, it just
coredumps. There is some problem with pixmap creation/usage from XPM in
the way it is done in gconf, so I just added some stock icons. It is even

Could someone test this still works on gtk-2.0 or 2.2 ?
Changes:
- change the wiget class 'button' in glade files to something known to
glade (GtkToolButton)
- use 'stock-id' property for toolbar buttons instead of "stock_pixmap"
- change unknown signal "pressed" to "clicked"
- remove manual setting of icons in gconf.c

[PATCH] Sync in core time granuality with filesystems
This patch corrects a problem that was originally added with the nanosecond
timestamps in stat patch. The problem is that some file systems don't have
enough space in their on disk inode to save nanosecond timestamps, so they
truncate the c/a/mtime to seconds when flushing an dirty node. In core the
inode would have full jiffies granuality.
This can be observed by programs as a timestamp that jumps backwards under
specific loads when an inode is flushed and then reloaded from disk.
The problem was already known when the original patch went in, but it
wasn't deemed important enough at that time. So far there has been only
one report of it causing problems. Now Tridge is worried that it will
break running Excel over samba4 because Excel seems to do very anal
timestamp checking and samba4 will supply 100ns timestamps over the
network.
This patch solves it by putting the time resolution into the superblock of
a fs and always rounding the in core timestamps to that granuality.
This also supercedes some previous ext2/3 hacks to flush the inode less
often when only the subsecond timestamp changes.
I tried to keep the overhead low, in particular it tries to keep divisions
out of fast paths as far as possible.
The patch is quite big but 99% of it is just relatively straight forward
search'n'replace in a lot of fs. Unconverted filesystems will default to a
1ns granuality, but may still show the problem if they continue to use
CURRENT_TIME. I converted all in tree fs.
One possible future extension of this would be to have two time
granualities per superblock - one that specifies the visible resolution,
and the other to specify how often timestamps should be flushed to disk,
which could be tuned with a mount option per fs (e.g. often m/atimes don't
need to be flushed every second). Would be easy to do as an addon if
someone is interested.

[PATCH] sys_stime needs a compat function
I realized that the best way to get the sys_time/sys_stime problem fixed is
to make sys_time 64 bit safe by using "time_t *" instead of "int *" and to
introduce two proper compat functions compat_sys_time and compat_sys_stime.
The prototype change of sys_time is transparent for 32 bit architectures
because both "int" and "time_t" are 32 bit. For 64 bit the type change
would be wrong but luckily no 64 bit architecture uses sys_time/sys_stime
in 64 bit mode. The patch makes the following change:
ia64 : Remove sys32_time, use compat_sys_time and
add (!!) compat_sys_stime to compat syscall table.
mips : Use compat_sys_time/compat_sys_stime in 32 bit syscall table.
Add #ifdef magic to compile sys_time/sys_stime and
compat_sys_time/compat_sys_stime only if needed.
parisc : Remove sys32_time, use compat_sys_time and compat_sys_stime.
ppc64 : remove sys32_time, ppc64_sys32_stime and ppc64_sys_stime.
Use common compat_sys_time, compat_sys_stime and sys_stime.
s390 : Use compat_sys_stime. Add #ifdef magic to compile
sys_time/sys_stime and compat_sys_time/compat_sys_stime only
if needed.
sparc64 : Use compat_sys_time/compat_Sys_stime in 32 bit syscall table.
um : Remove um_time and um_stime. Use common functions sys_time and
sys_stime. This adds a CAP_SYS_TIME check to UMs stime call.
x86_64 : Remove sys32_time. Use compat_sys_time and compat_sys_stime
in 32 bit syscall table.
The original stime bug is fixed for mips, parisc, s390, sparc64 and
x86_64. Can the arch-maintainers please take a look at this?

[PATCH] compile with -ffreestanding
For the kernel, it would be logical to use -ffreestanding. The kernel is
not a hosted environment with a standard C library.
The gcc option -ffreestanding is supported by both gcc 2.95 and 3.4, which
covers the whole range of currently supported compilers.
Regarding changes caused by this patch:
Andi Kleen reported:
Newer gcc rewrites sprintf(buf,"%s",str) to strcpy(buf,str) transparently.
This is only true with unit-at-a-time (disabled on i386 but enabled on
x86_64). The Linux kernel doesn't offer a standard C library, and such
transparent replacements of kernel functions with builtins are quite
fragile.
Even with -ffreestanding, it's still possilble to explicitely use a gcc
builtin if desired.

[PATCH] ext3: support for EA in inode
1) intent of the patch is to get possibility to store EAs in the body of large
inode. it saves space and improves performance in some cases
2) the patch is quite simple: it works the same way original xattr does, but
using other storage (inode body). body has priority over separate block.
original routines (ext3_xattr_get, ext3_xattr_list, ext3_xattr_set) are
renamed to ext3_xattr_block_*. new routines that handle inode storate are
added (ext3_xattr_ibody_get, ext3_xattr_ibody_list, ext3_xattr_ibody_set).
routines ext3_xattr_get, ext3_xattr_list and ext3_xattr_set allow user to
accesss both the storages transparently
3) the change makes sense on filesystem with inode size >= 256 bytes only.
2.4 kernels don't support such a filesystems, AFAIK. 2.6 kernels do support
and ignore EAs stored in a body w/o the patch
4) debugfs and e2fsck need to be patched to deal with EAs in inode
the patch will be sent later
5) testing results:
a) Andrew Samba Master (tridge) has done successful tests
b) we've been using ea-in-inode feature in Lustre for many months

[PATCH] Reduce i_sem usage during file sync operations
We hold i_sem during the various sync() operations to prevent livelocks:
if another thread is dirtying the file, a sync() may never return.
Or at least, that used to be true when we were using the per-address_space
page lists. Since writeback has used radix tree traversal it is not possible
to livelock the sync() operations, because they only visit each page a single
time.
sync_page_range() (used by O_SYNC writes) has not been holding i_sem for quite
some time, for the above reasons.
The patch converts fsync(), fdatasync() and msync() to also not hold i_sem
during the radix-tree-based writeback.
Now, we _do_ still need to hold i_sem across the file->f_op->fsync() call,
because that is still based on a list_head walk, and is still livelockable.
But in the case of msync() I deliberately left i_sem untaken. This is because
we're currently deadlockable in msync, because mmap_sem is already held, and
mmap_sem nexts inside i_sem, due to direct-io.c.
And yes, the ranking of down_read() veruss down() does matter:
Task A Task B Task C
down_read(rwsem)
down(sem)
down_write(rwsem)
down(sem)
down_read(rwsem)
C's down_write() will cause B's down_read to block. B holds `sem', so A will
never release `rwsem'.
So the patch fixes a hard-to-hit triple-task deadlock, but adds a possible
livelock in msync(). It is possible to fix sys_msync() so that it takes i_sem
outside i_mmap_sem. Later.

[PATCH] ext3: handle attempted double-delete of metadata.
This patch improves ext3's ability to deal with corruption on-disk. If we
try to delete a metadata block twice, we confuse ext3's internal revoke
error-checking, resulting in a BUG(). But this can occur in practice due
to a corrupt indirect block, so we should attempt to fail gracefully.
Downgrade the assert failure to a JH_EXPECT_BH failure, and return EIO when
it occurs.
This is easily reproduced with a sample ext3 fs image containing an inode
which references the same indirect block more than once. Deleting that
inode will BUG() an unfixed kernel with:
Assertion failure in journal_revoke() at fs/jbd/revoke.c:379:
"!buffer_revoked(bh)"

[PATCH] ext3: handle attempted delete of bitmap blocks.
This patch improves ext3's ability to deal with corruption on-disk. If we
ever get a corrupt inode or indirect block, then an attempt to delete it
can end up trying to remove any block on the fs, including bitmap blocks.
This can cause ext3 to assert-fail as we end up trying to do an ext3_forget
on a buffer with b_committed_data set.
The fix is to downgrade this to an IO error and journal abort, so that we
take the filesystem readonly but don't bring down the whole kernel.
Make J_EXPECT_JH() return a value so it can be easily tested and yet still
retained as an assert failure if we build ext3 with full internal debugging
enabled. Make journal_forget() return an error code so that in this case
the error can be passed up to the caller.
This is easily reproduced with a sample ext3 fs image containing an inode
whose direct and indirect blocks refer to a block bitmap block. Allocating
new blocks and then deleting that inode will BUG() with:
Assertion failure in journal_forget() at fs/jbd/transaction.c:1228:
"!jh->b_committed_data"
With the fix, ext3 recovers gracefully.

[PATCH] ext3: cleanup handling of aborted transactions.
This patch improves ext3's error logging when we encounter an on-disk
corruption. Previously, a transaction (such as a truncate) which encountered
many corruptions (eg. a single highly-corrupt indirect block) would emit
copious "aborting transaction" errors to the log.
Even worse, encountering an aborted journal can count as such an error,
leading to a flood of spurious "aborting transaction: Journal has aborted"
errors.
With the fix, only emit that message on the first error. The patch also
restores a missing \n in that printk path.

[PATCH] Permit nommu MAP_SHARED of memory backed files
The attached patch applies some further fixes and extensions to the nommu mmap
implementation:
(1) /proc/maps distinguishes shareable private mappings and real shared
mappings by marking the former with 's' and the latter with 'S'.
(2) Rearrange and optimise the checking portion of do_mmap_pgoff() to make it
easier to follow.
(3) Only set VM_SHARED on MAP_SHARED mappings. Its presence indicates that the
backing memory is supplied by the underlying file or chardev.
VM_MAYSHARE indicates that a VMA may be shared if it's a private VMA. The
memory for a private VMA is allocated by do_mmap_pgoff() from a kmalloc
slab and then the file contents are read into it before returning.
(4) Permit MAP_SHARED + PROT_WRITE on memory-backed files[*] and chardevs to
indicate a contiguous area of memory when its get_unmapped_area() is
called if the backing fs/chardev is willing.
[*] file->f_mapping->backing_dev_info->memory_backed == 1
(5) Require chardevs and files that support to provide a get_unmapped_area()
file operation.
(6) Made sure a private mapping of /dev/zero is possible. Shared mappings of
/dev/zero are not currently supported because this'd need greater
interaction of mmap with the chardev driver than is currently supported.
(7) Add in some extra checks from mm/mmap.c: security, file having write
access for a writable shared mapping, file not being in append mode.
(8) Only account the mapping memory if it's allocated here; memory belonging
to a shared chardev or file is not accounted.
With this patch it should be possible to map contiguous flash files directly
out of ROM simply by providing get_unmapped_area() for a read-only/shared
mapping.
I think that it might be worth splitting do_mmap_pgoff() up into smaller
subfunctions: one to handle the checking, one to handle shared mappings and
one to handle private mappings.

[PATCH] Fix nommu MAP_SHARED handling
The attached patch does the following things:
(1) It uniquifies permitted overlapping VMAs (eg: MAP_SHARED on chardevs) in
nommu_vma_tree. Identical entries break the assumptions on which rbtrees
work. Since we don't need to share VMAs in this case, we uniquify such
VMAs by using the pointer to the VMA. They're only kept in the tree for
/proc/maps visibility.
(2) Extracts VMA unlinking into its own function so that the source is
adjacent to the VMA linking function.
(3) No longer releases memory belonging to a shared chardev or file (the
underlying driver is expected to provide mappable memory).
(4) Frees the file attached to a VMA whether or not that VMA is shared or is
a memory-mapped I/O mapping.

on !CONFIG_MMU.
(2) vm_rb is now used to keep track of the VMAs in an rbtree rather than
adding a separate list.
(3) mm_tblock_struct is now vm_list_struct.
(4) put_vma() now calls vma->vm_ops->close() if available on nommu.
(5) A dummy generic_file_vm_ops has been provided. It does nothing, but
permits tiny-shmem to compile.
tiny-shmem and ramfs still need attention, such that files contained
therein can be mmapped shared-writably to some extent on nommu.

[PATCH] FRV: Add FDPIC ELF binary format driver
The attached patch adds a new binary format driver that allows a special
variety of ELF to be used that permits the dynamic sections that comprise an
executable, its dynamic loader and its shared libaries and its stack and data
to be located anywhere within the address space.
This is used to provide shared libraries and shared executables (at least, as
far as the read-only dynamic sections go) on uClinux. Not only that, but the
same binaries can be run on MMU linux without a problem.
This is achieved by:
(1) Passing loadmaps to the dynamic loader (or to a statically linked
executable) to indicate the whereabouts of the various dynamic sections.
(2) Using a GOT inside the program.
(3) Passing setup_arg_pages() the stack pointer to be.
(4) Allowing the arch greated control over how an executable is laid out in
memory in MMU Linux.
(5) Rewriting mm/nommu.c to support MAP_PRIVATE on files, thus allowing _mmap_
to handle sharing of private-readonly mappings.

[PATCH] FRV: Better mmap support in uClinux
The attached patch changes mm/nommu.c to better support mmap() when MMU

This was discussed on the uclibc mailing list in a thread revolving around the
following message:
Date: Thu, 1 Apr 2004 12:05:50 +1000
From: David McCullough <davidm@snapgear.com>
To: David Howells <dhowells@redhat.com>
Cc: Alexandre Oliva <aoliva@redhat.com>, uclibc@uclibc.org
Subject: Re: [uClibc] mmaps for malloc should be private
Message-ID: <20040401020550.GG3150@beast>
The revised rules are:
(1) Anonymous mappings can be shared or private, read or write.
(2) Chardevs can be mapped shared, provided they supply a get_unmapped_area()
file operation and use that to set the address of the mapping (as a frame
buffer driver might do, for instance).
(3) Files (and blockdevs) cannot be mapped shared since it is not really
possible to honour this by writing any changes back to the backing device.
(4) Files (or sections thereof) can be mapped read-only private, in which case
the mapped bit will be read into memory and shared, and its address will
be returned. Any excess beyond EOF will be cleared.
(5) Files (or sections thereof) can be mapped writable private, in which case
a private copy of the mapped bit will be read into a new bit memory, and
its address will be returned. Any excess beyond EOF will be cleared.
Mappings are per MM structure still. You can only unmap what you've mapped.
Fork semantics are irrelevant, since there's no fork.
A global list of VMA's is maintained to keep track of the bits of memory
currently mapped on the system.
The new binfmt makes use of (4) to implement shared libraries.

[PATCH] kill off highmem_start_page
People love to do comparisons with highmem_start_page. However, where
CONFIG_HIGHMEM=y and there is no actual highmem, there's no real page at
*highmem_start_page.
That's usually not a problem, but CONFIG_NONLINEAR is a bit more strict and
catches the bogus address tranlations.
There are about a gillion different ways to find out of a 'struct page' is
highmem or not. Why not just check page_flags? Just use PageHighMem()
wherever there used to be a highmem_start_page comparison. Then, kill off
highmem_start_page.
This removes more code than it adds, and gets rid of some nasty

The attached patch fixes a number of problems in the VM routines:
(1) Some inline funcs don't compile if CONFIG_MMU is not set.
(2) swapper_pml4 needn't exist if CONFIG_MMU is not set.
(3) __free_pages_ok() doesn't counter set_page_refs() different behaviour if
CONFIG_MMU is not set.
(4) swsusp.c invokes TLB flushing functions without including the header file
that declares them.
CONFIG_SHMEM semantics:
- If MMU: Always enabled if !EMBEDDED
- If MMU && EMBEDDED: configurable
- If !MMU: disabled

[PATCH] GP-REL data support
The attached patch makes it possible to support gp-rel addressing for small
variables. Since the FR-V cpu's have fixed-length instructions and plenty of
general-purpose registers, one register is nominated as a base for the small
data area. This makes it possible to use single-insn accesses to access
global and static variables instead of having to use multiple instructions.
This, however, causes problems with small variables used to pinpoint the
beginning and end of sections. The compiler assumes it can use gp-rel
addressing for these, but the linker then complains because the displacement
is out of range.
By declaring certain variables as arrays or by forcing them into named
sections, the compiler is persuaded to access them as if they can be outside
the displacement range. Declaring the variables as "const void" type also
works.

[PATCH] capset returns -EPERM when pid==current->pid
In the current kernel/capability.c:sys_capset() code, permission is
denied if CAP_SETPCAP is not held and pid is positive. pid=0 means use

CAP_SETPCAP is required to use this function, and does not mention the

[PATCH] Steal a Character To Create a Revision Number
Pablo Neira <pablo@eurodev.net> came up with the idea of stealing the
last byte in the (already nul-terminated) name of a target/match to

That patch motivated me to clean up the match and target searching in
ip_tables, which makes this patch more trivial. I also renamed

[PATCH] Clean up the kmod handling code in iptables.c
We now have a convenient kmod macro try_then_request_module().
1) Split our current "generic" function into separate
find_target_lock(), find_table_lock() and find_match_lock()
functions explicitly.
2) Have those functions do try_module_get() for us, and fix up the one
caller who didn't do that anyway.
3) Have the caller use try_then_request_module().
4) Remove __ipt_mutex_up() and __ipt_find_target_lock() which weren't
used (even in patch-o-matic AFAICT).
This cleanup takes us closer to using standard list macros everywhere,
and makes the version patch simpler.

[PATCH] Remove Randomness in Selecting NAT IP Address
We currently choose a "random" IP address to NAT to, where we have a
range. Martin Josefsson pointed out that he uses the SAME target in
iptables because changing IP addresses breaks Internet banking sites
(among others) which assume the customer will be coming from a
consistent IP address.
In fact, we spend a fair bit of effort trying to balance the number of
connections we NAT to each IP address. We can come pretty damn close
just hashing the source and destination IP addresses, and it has the
consistency property which is so desirable, as well as being faster.

[PATCH] Remove do_extra_mangle: double NAT on LOCAL_OUT
On NF_IP_LOCAL_OUT, when destination NAT changes the destination

[PATCH] Don't try too hard to NAT to unique tuple
On NF_IP_LOCAL_OUT or NF_IP_PRE_ROUTING, if destination NAT is not
sufficient to create a unique tuple, we try changing the source port
as well. However, this is also not strictly necessary: if the tuple
is not unique, we will also try to change the source on the
NF_IP_POST_ROUTING hook.
When we finally confirm the connection, if the tuple is still not
unique the packet will be dropped (this is required anyway as we could
race: the conntrack is not placed in the hash until the packet is
about to leave the box anyway).
In fact, we only need best effort *everywhere*.

[ARM] Fix slab corruption issues triggered with pud_t integration.
When the page tables are wrapped from 4 levels to 2 levels, the new
MM code requires PMD_SHIFT to match PUD_SHIFT, which must also
match PGDIR_SHIFT. If PMD_SHIFT is smaller than PUD_SHIFT, we risk
freeing a still-in-use table (== page) which can then get re-used
for the slab cache.
Testing and inspection shows that there isn't any real benefit from
keeping PMD_SHIFT set to 20.
In addition, add some comments concerning the granularity of
alloc_init_section() and fix a missing PMD assignment in the
rebooting code. Somehow we managed to get away with that, although
it is actually wrong. Maybe I've just been lucky until now.

The initial implementation of NFS direct reads was entirely synchronous.
The direct read logic issued one NFS READ operation at a time, and waited

read requests, this is unnecessarily slow.
This patch changes the NFS direct read path to dispatch NFS READ operations
for a single direct read request in parallel and wait for them once. The
direct read path is still synchronous in nature, but because the NFS READ
operations are going in parallel, the completion wait should be much shorter.

NFSv2/v3/v4: ESTALE should not be a permanent condition on directories.
Although it usually means that someone has deleted a file on the server,
the ESTALE error may also indicate that the sysadmin has used exportfs to
deny our client access to the server. Most NFS implementations therefore
consider it a non-permanent condition, and allow inodes to "recover" when
the sysadmin re-enables access.
If, however, you want to work with broken servers, like unfsd, that reuse
filehandles for new files after the original file gets deleted, then
"recovery" is impossible, since it may be that the filehandle now points
to a different file. Note that this is broken server behaviour that may
happen even without us ever seeing the ESTALE error.
In order to minimize (but we can never eliminate entirely) this race
condition on unfsd servers, Linux has traditionally made ESTALE a
permanent condition on all filehandles except the root filehandle.
The problem is that if we apply this strict staleness criterion to
directories (particularly so for he current directory), then all
processes will need to re-walk the path starting from the mount point,
in order to recover from the sysadmin intervention case. As this is not
usual on other *NIX implementations, and may in any case be undermined by
caching rules etc, this is being seen as a usability problem.
This patch makes ESTALE a non-permanent condition on directories, but
preserves the current behaviour for non-directories.

[PATCH] s390: SCLP device driver cleanup
From: Peter Oberparleiter <peter.oberparleiter@de.ibm.com>
sclp: core driver cleanup
Details:
- moved signal shutdown (quiesce) handling into a separate file
- cleanup of SCLP core driver:
. introduced driver states instead of bits
. introduced request retry count and retry limit
. sclp_add_request now returns an error code if a request couldn't be started
. introduced separate request structure for init_mask requests to simplify
code
. request timer is now manually checked in sclp_sync_wait because timer
interrupts are disabled in this context
. removed busy timer - request timer now handles both cases
. split up sclp_start_request into __sclp_start_request and sclp_process
queue
. removed sclp_error_message (unused)
. introduced sclp_check_handler function to split up initial init mask
test from standard init mask request processing
. introduced sclp_deactivate and sclp_reactivate for simplified reboot
event handling (and potential use in suspend/resume scenario)
. added protection against multiple concurrent init mask calls
- minor changes in SCLP core driver:
. updated comments
. renamed functions to be consistent with "function name starts with __ =>
needs lock"
. renamed internal functions for consistency reasons
. introduced inlined helper functions to simplify code
. moved EXPORT_SYMBOL definitions next to function definition
- changes in sclp console driver
. removed callback recursion to prevent stack overflow
- changes to CPI module
. added check for sclp_add_request return code
. changed printks to specify a message level
- changes to generic sclp tty layer
. removed timed buffer retry after error (timers may not work in some
situations)
. introduced return code for sclp_emit_buffer
- changes to sclp tty driver
. removed callback recursion
- changes to sclp vt220 driver
. removed callback recursion
. removed timed buffer retry after error
- modified sclp_init_mask to prevent problems with some compiler versions

To have a fast selection of the appropriate ptrace option to use next,

0 = don't do singlestepping
1 = singlestep a syscall
2 = singlestep a "non syscall" instruction

advanced sysemu is in use (that does it itself).

[PATCH] uml: Fix setting of TIF_SIGPENDING
From: Bodo Stroesser <bstroesser@fujitsu-siemens.com>
My older patch, that sets TIF_SIGPENDING after an ptrace-interception
in syscall_trace() is wrong.
Some syscalls want to be called without any signal pending. If a signal
is pending on syscall-entry, they immediately return with -ERESTARTNOINTR.
Thus, on return to user, the pending signals can be processed and the
kernel will lower eip by 2 to have the syscall restarted after that.
Since my change sets TIF_SIGPENDING on the entry and exit interception,
stracing such a syscall looped! Try "strace ls" to see what happens.
Fix: set TIF_SIGPENDING on the exit interception only. This avoids the
loop and is enough for security.

[PATCH] uml: system call restart fixes
From: Bodo Stroesser
The implementation of sys_sigreturn() and sys_rt_sigreturn() in UML
must be changed.
This is necessary, since the return value of sys_*_sigreturn()
is the value of eax in the thread, that was interrupted by the
signal handler. If accidentaly eax contains -ERESTART_*, orig_eax
*must* be -1 to avoid syscall restart processing in kern_do_signal().
If orig_eax is >=0, eip might be lowered by 2, the process will fail.
In UML PT_REGS_SYSCALL_NR() or UPT_SYSCALL_NR() have to be used
instead of orig_eax.
While writing and testing an exploit for this, I saw that for most
interrupts, the syscall number is undefined. So even on a return from
interrupt a wrong syscall restart handling could happen.
And also: UML resumes a process with ptrace(PTRACE_SYSCALL/SYSEMU/SINGLESTEP
when a syscall in UML in SKAS mode has been processed. But since there
is a valid syscall number in the host's orig_eax, the host could do
a wrong syscall restarting if the syscall in UML was a sigreturn() returning
-ERESTART* To avoid this, in SKAS -1 should be written to regs.orig_eax
before restore_registers().

[PATCH] uml: kill host processes properly
This patch changes how UML kills ptraced processes in order to be more
correct in the presence of the ptrace changes in 2.6.9. It used to be that
ptrace stopped processes could simply be killed and they would go away. Now,
there's a new run state for ptraced processes which doesn't receive signals
until they are PTRACE_KILLed or PTRACE_CONTinued. So, this patch kills the
process, as usual, then PTRACE_KILL and PTRACE_CONT. This is done in
os_kill_ptrace_process() for use from skas mode, and in tracer() when it
sees a child process getting a SIGKILL.

[PATCH] uml: make vsyscall page into process page tables
From: Bodo Stroesser
To make the vsyscall-page available for copy_from_user() and
ptrace(), we should use kernel's "gate-vma" mechanism.
Therefore we need a valid page structure. To have this, one
page (or more) is allocated at boot time, the contents of the
vsyscall-page is copied into this page and the page's pte is
inserted in swapper's pagetables.
Now it will be copied into the pagetables of all processes.
Note: this alone doesn't work, since FIXADDR_USER_START and
FIXADDR_USER_END are not yet defined correctly. Also
access_ok_skas() does not yet grant read accesses to
pages not in the normal user area.
Risks:
Please check the first hunk! I don't know, whether this change is OK.
Maybe fixrange_init() is wrong anyway with 3-level-pagetables?
Here access_ok_skas() and FIXADDR_USER_XXXX are fixed.
Now everything should work fine, while the processes are
running. But if a process crashes, the vsyscall-page will
not be dumped.

[PATCH] uml: add elf vsyscall support
From: Bodo Stroesser
This is the first patch of a series of four.
These patches allow the use of sysenter-systemcalls in UML
if the host support sysenter.
Some facts have to be noted:
- the sysenter instruction does not save anything, not even the
return address. Thus the host-kernel builds a stackframe with an
fixed return address for the backjump to the vsyscall-page. All
kernels that support sysenter thus must have a vsyscall-page
- The hosts vsyscall-page is visible in all memory-contexts on the
host, even in those of the processes running on UML. This cannot
be changed.
So the best way to implement sysenter is to integrate the host's
vsyscall-page into UML, if available.
This patch creates a new source file containing an UML
initialization function. The function scans the Elf-auxiliary vector
that is prepared by the host for relevant information about:
- vsyscall elf-header
- vsyscall entry
- machine type (called "platform", e.g. "i586" or "i686")
- hardware capabilities
These informations are inserted into the Elf-auxiliary-vector that is
generated if an UML process calls "execXX()". If the information from
the auxiliray-vector is not complete, UML uses the previos default
values, with one exception: if the host has no vsyscall-page, UML now
does no longer insert AT_SYSINFO or AT_SYSINFO_EHDR elements. (I think,
that's better than writing dummies)
Since the host's vsyscall-page is always visible to UML processes, this
change is enough to let UML with an i686-compiled glibc use sysenter.
what's missing:
- is_syscall() in SKAS cannot access the code in the vsyscall-page via
copy_from_user(), thus singlesteppers still could break out. (Note:
that's not new, if someone jumps willingly to the sysenter-entry in
the vsyscall-page, he can do that without the patch, too).
- a debugger cannot access the code in the vsyscall-page via
ptrace( PEEKTEXT, ...)
Risks:
could there by any feature of the host's processor, that is indicated in
the hardware capabilities, but must not be used in UML?

[PATCH] uml: terminal cleanup
This is a major cleanup of the uml terminal drivers and console handling
(console as in "where the kernel messages go to", not as in "linux
virtual terminals"). The changes in detail:
(1) There is a new console driver calles "stderr" which (as the name
implies) simply dumps all kernel messages to stderr. That one
is registered very early in the boot process via console_initcall()
and will print every almost kernel message instantly: Both very
early in the boot process and very late in shutdown.
Note that this is not enabled by default, see below for details.
(2) Ditched the early-console-init hackery in stdio_console.c
(open_console(NULL) + related stuff) into the waste basket, not
needed any more as you can use the new stderr console driver to
get the kernel messages if your kernel crashes very early in the
boot process.
(3) Handle console initialitation for the uml stdio console and
virtual serial lines the normal way using the console->setup()
function. Now all kernel messages appear on your console device
once it is initialized without any dirty tricks.
(4) The (2) changes allow a number of further cleanups: As we don't
open a line without a tty_struct any more we can ...
* hook struct line into tty->driver_data
* pass around tty_struct instead of struct line everythere
* get rid of some trivial wrappers in ssl.c and stdio_console.c
because we can get struct line via tty_struct all the time now.
(5) Change the ordering in the arch/um/drivers/Makefile and thus
the link and initialization order to make sure the stdio console
and not the virtual serial line is the default console device.
(6) Fixed a number of Documentation/CodingStyle issues within the
code (not systematically, but usually just the places I was
touching anyway or where it bugged me while browsing the code
because it was hard to read).
Looks like that cleanup also fixed some strange tty issues I've seen in
the past (like console getty not responding to input sometimes, suse's
/sbin/blogd causing trouble).
Finally some usage notes for using the new stderr console:
If the stderr console is enabled, then it is the default console device
because it registeres very early in the boot process. But as it isn't
linked to a tty device this makes init unhappy, you'll see "can't open
initial console" error messages. Because you usually don't want that
the stderr console is turned off by default. That also maintains the
behavior that /dev/tty0 is the first console device registered and thus
the default console.
There are basically two useful use cases for the stderr console:
(1) Your kernel dies before the normal console device is initialized
and thus you don't see any messages. Just enable the stderr
console to see them by adding "stderr=1" to the kernel command line.
(2) You want to have the kernel messages on both stderr and your
console terminal device. Try something like this:
$ ./linux stderr=1 console=stderr console=ttyS0 ssl0=xterm
This example sets up the console on a virtual serial line and
pops up an xterm for that.

[PATCH] hostfs: uml: add some other pagecache methods
This is a follow-up to my previous "hostfs - uml: set .sendfile to
generic_file_sendfile" patch. I was asking whether other methods should have
been added, and comparing with ext3 I found some more ones.
However, I have not specific clues about them: I know they use the pagecache,
which relies on *page methods, which are defined by hostfs. So I think it
could work.
I have a doubt, whether hostfs needs the commented out method below:
static struct address_space_operations hostfs_aops = {
.writepage = hostfs_writepage,
.readpage = hostfs_readpage,
/* .set_page_dirty = __set_page_dirty_nobuffers, */
.prepare_write = hostfs_prepare_write,
.commit_write = hostfs_commit_write
};
Hostfs does not have a underlying device (and I have some rough idea that
buffers cache block devices data), so I wonder if that is needed or not.

[PATCH] uml: unregister signal handlers at reboot
From: Bodo Stroesser <bstroesser@fujitsu-siemens.com>
In most cases reboot failed on my system. After "Restarting system.", UML
exited without further messages. I found an SIGIO being processed by
sig_handler() resp. sig_handler_common_skas(). Don't know, why this exits,
maybe the context is no longer valid at this time. So, I changed the sequence
in the reboot part of main() to stop the timers and disable the fds before
unblocking the signals. Since this wasn't enough, I also added
set_handler(SIGXXX, SIG_IGN) calls to disable_timer() and
deactivate_all_fds(). Now reboot works fine in SKAS and it still works in TT.

[PATCH] uml: redo the signal delivery mechanism
This patch rips out the old signal delivery mechanism and replaces it with a
sane one.
Specifically, UML used to capture a host signal frame and use it as a template
for its own signal frames. This was a worthy idea, because it promised a
degree of architecture-independence for this part of UML, but impractical.
There are some environments, notably 32 bit emulation on a 64 bit box, where
you can't use the host signal frame as a template for your own. Plus, this
code is as complicated, even to someone who understands what it's doing, as
the standard fill-in-a-structure-and-write-it-to-the-stack. For everyone
else, it is incomprehensible.
So, this reimplements signal handling in the way that everyone else does. It
gives up on architecture independence, and moves this code into the
x86-specific stuff.

[PATCH] m32r: Make kernel headers for mutual exclusion
Here is a patch to update kernel headers for mutual exclusion,
atomic.h, bitops.h and semaphore.h of m32r.
This patch is for making these headers publishable to userland.
* include/asm-m32r/assembler.h (M32R_LOCK, M32R_UNLOCK):
Define M32R_LOCK and M32R_UNLOCK macros. For SMP configuration,
these macros are expanded to m32r's LOCK and UNLOCK instructions.
While, for UP configuration, these are simply expanded to m32r's
LD(load) and ST(store) instructions, respectively.
* include/asm-m32r/atomic.h, include/asm-m32r/bitops.h,
include/asm-m32r/semaphore.h:
- Change macros from LOAD and STORE to M32R_LOCK and M32R_UNLOCK,
respectively. It is because LOAD and STORE are too generic words.
- Change inline to __inline__.
Retrieve __inline__ modifiers for functions which are placed
outside of __KERNEL__ region in these headers, because those
functions might be included and used from ISO C program in
userland.
Currently, it seems that these headers are allowed to be included from
userland. Indeed, they are kernel stuff, but these headers provide
useful definitions and functions even for userland applications, I think.

[PATCH] m32r: Update ptrace.c for multithread debugging
This patch updates ptrace.c to support multithread debugging. So far, only
one breakpoint's location was kept by kernel, however, in the multithreaded
application's debug, it is required to kept multi-point breakpoint locations
by kernel.
In this implementation, maximum number of MAX_TRAPS(=10 (by default))
breakpoint's information will be kept in the "debug_trap" member of the
thread_struct for each thread.
* include/asm-m32r/processor.h:
Modify debug_trap struct to keep multipoint breakpoint locations
for multithread debugging.
* arch/m32r/kernel/ptrace.c:
- Update to support multithread debugging.
- Remove unused functions, withdraw_debug_trap_for_signal() and
embed_debug_trap_for_signal().

[PATCH] m32r: Support pgprot_noncached()
This patch updates include/asm-m32r/pgtable.h to add pgprot_noncached().
It is required to fix a problem of an userspace application, which mmaps
io registers.
This patch also modifies drivers/video/fbmem.c to support noncachable
framebuffer access for m32r.
In this routine, pgprot_writecombine() is used hopefully, even though
the current m32r never does write-combining or write-coalescing...
Please apply this.
* include/asm-m32r/pgtable.h
(pgprot_noncached, pgprot_writecombine): Newly added.
* drivers/video/fbmem.c (fb_mmap): Add m32r support.

[PATCH] typeof(dev->power.saved_state)
arch/arm/common/sa1111.c: In function `sa1111_suspend':
arch/arm/common/sa1111.c:816: warning: assignment from incompatible pointer type
This is a rather annoying, and IMHO pointless warning. First question:
what is the reasoning for using an array of unsigned bytes here? Are we
expecting to power manage devices which only have byte wide registers?
In reality, devices have half-word and word sized registers as well, which
means that dev->power.saved_state actually points to device specific data
(or even device driver specific data) for the device. As such, it makes
far more sense for this to be a 'void *'.
I'd rather not go around the ARM kernel tree adding pointless casts to 'u8
*' and back again because the wrong type for this was picked in the
structure definition, so here's a patch which changes this to void *.

[PATCH] x86_64: Scheduler support for AMD CMP
Scheduler support for AMD CMP
AMD dual core looks like HT but isn't really. Hide it from the scheduler.
This works around problems with the domain scheduler. Also probably gives
slightly better scheduling and disables SMT nice which is harmful on dual
core.
We still display it like HT in /proc/cpuinfo. This is to make it appear the
same to license managers so that they count dual cores only as a single
physical CPU.

[PATCH] x86_64: Add SRAT NUMA discovery to x86-64.
Add SRAT NUMA discovery to x86-64.
Previously the NUMA nodes on Opteron systems were directly read from the
hardware registers of the northbridge.
This version also supports reading it from the more generic ACPI SRAT table.
This allows to support NUMA on all kinds of systems and in general gives more
flexibility, but needs a bit of BIOS support.
This implementation was not done before because the SRAT specification had a
bad license from Microsoft that didn't allow to implement it on other OS. Now
that ACPI 3.0 is released and SRAT is part of it that isn't a concern anymore.
One side effect of this is that holes not described in SRAT (e.g. usually the
640K DOS and 4GB PCI memory holes) will not included in the nodes and won't
get mem_map entries allocated. This may have side effects for some drivers.
Some support for handling dual core AMD CPUs is included.
SLIT parsing is done in a later patch. Depends on earlier patches to split up
the ACPI boot parsing and to add better CMP support on x86-64.
Can be disabled with numa=noacpi

[PATCH] x86_64: Split ACPI boot table parsing
Split ACPI boot table parsing
Split ACPI boot table parsing into two parts. First a acpi_boot_table_init()
call that initializes the basic ACPI table parsing machinery and discovers the
RSDP, and then another call to actually parse the various boot tables.
This is needed for a followon patch that implements SRAT support, because
nodes need to be set up before the other ACPI tables can be parsed.
On x86-64 I moved the early initialization very early because that is needed
for the SRAT parser.
On i386 it should be a nop.

The kernel text mapping aliases part of the physical memory and needs its

It is needed so that update tools that update kernels from vendors know which

hairy heuristics to find out if it's grub or lilo or .. that installed the
kernel. Those heuristics are fragile in the presence of more than one
bootloader (which isn't that uncommon in OS upgrade situations).

[PATCH] x86: remove data-header and code overlap in boot/setup.S
The setup.S data and code is not cleanly separated. The current space
reserved for setup header is not enough to fit the complete header. As a
result, part of the header (EDDBUF) will overwrite the initial code.
I haven't seen any negative impact of this bug. As, by the time the setup
code is overwritten, we would have finished executing it anyway. But, I
think it is better to separate the header and code and prevent this
data_overwriting_the_code condition.
The atatched patch adds some space in the header to fit all the data listed
in Documentation/i386/zero-page.txt for both i386 and x86_64 (and updates
zero-page.txt).

[PATCH] ppc64: tweaks to ppc64 cpu sysfs information
Currently the ppc64 sysfs code registers an entry for each possible cpu in

entries are needed to control onlining of the cpus. However, this is done
even if CONFIG_HOTPLUG_CPU is not set, or if it is not a hotplug capable
(DLPAR) machine, which is a bit misleading. Secondly it also registers all
the other sysfs entries (mostly performance monitoring controls) on all
possible cpus, although they are quite meaningless on non-online cpus.
This patch alters the code to only register sysfs directories at boot for
cpus which are either online or could be onlined (cpu is possible, and
CONFIG_HOTPLUG_CPU and an lpar machine). Furthermore, the entries apart
from 'online' itself and 'physical_id' are only registered for online CPUs
(and deregistered again if a cpu goes offline).

[PATCH] PPC debug setcontext syscall implementation.
Add a debugging interface for PowerPC that allows signal handlers (or any
jump to a context, really) to perform debug functions. It allows the a
user program to turn on single-stepping, for instance, and the thread will
get a trap after executing the next instruction. It can also (on supported
PPC processors) turn on branch tracing and get a trap after the next branch
instruction is executed. This is useful for in-application debugging.
Note that you can enable single-stepping on x86 processors directly from
signal handlers. Newer x86 processors have the equivalent of a
branch-trace bit in the IA32_DEBUGCTL MSR and could have similar function
to this syscall. Most other processors could benefit from a similar
interface, except for ARM which is extraordinarily broken for debugging.
Future uses of this could be adding the ability to set the hardware
breakpoint registers from a signal handler.

[PATCH] alloc_large_system_hash: NUMA interleaving
NUMA systems running current Linux kernels suffer from substantial inequities
in the amount of memory allocated from each NUMA node during boot. In
particular, several large hashes are allocated using alloc_bootmem, and as
such are allocated contiguously from a single node each.
This becomes a problem for certain workloads that are relatively common on
big-iron HPC NUMA systems. In particular, a number of MPI and OpenMP
applications which require nearly all available processors in the system and
nearly all the memory on each node run into difficulties. Due to the uneven
memory distribution onto a few nodes, any thread on those nodes will require a
portion of its memory be allocated from remote nodes. Any access to those
memory locations will be slower than local accesses, and thereby slows down
the effective computation rate for the affected CPUs/threads. This problem is
further amplified if the application is tightly synchronized between threads
(as is often the case), as they entire job can run only at the speed of the
slowest thread.
Additionally since these hashes are usually accessed by all CPUS in the
system, the NUMA network link on the node which hosts the hash experiences
disproportionate traffic levels, thereby reducing the memory bandwidth
available to that node's CPUs, and further penalizing performance of the
threads executed thereupon.
As such, it is desired to find a way to distribute these large hash
allocations more evenly across NUMA nodes. Fortunately current kernels do
perform allocation interleaving for vmalloc() during boot, which provides a
stepping stone to a solution.
This series of patches enables (but does not require) the kernel to allocate
several boot time hashes using vmalloc rather than alloc_bootmem, thereby
causing the hashes to be interleaved amongst NUMA nodes. In particular the
dentry cache, inode cache, TCP ehash, and TCP bhash have been changed to be
allocated in this manner. Due to the limited vmalloc space on architectures
such as i386, this behavior is turned on by default only for IA64 NUMA systems
(though there is no reason other interested architectures could not enable it
if desired). Non-IA64 and non-NUMA systems continue to use the existing
alloc_bootmem() allocation mechanism. A boot line parameter "hashdist" can be
set to override the default behavior.
The following two sets of example output show the uneven distribution just
after boot, using init=/bin/sh to eliminate as much non-kernel allocation as
possible.

While not perfectly even, we can see that there is a substantial improvement
in the spread of memory allocated by the kernel during boot. The remaining
uneveness may be due in part to further boot time allocations that could be
addressed in a similar manner, but some difference is due to the somewhat
special nature of node 0 during boot. However the uneveness has fallen to a
much more acceptable level (at least to a level that SGI isn't concerned
about).
The astute reader will also notice that in this example, with this patch
approximately 256 MB less memory was allocated during boot. This is due to
the size limits of a single vmalloc. More specifically, this is because the
automatically computed size of the TCP ehash exceeds the maximum size which a
single vmalloc can accomodate. However this is of little practical concern as
the vmalloc size limit simply reduces one ridiculously large allocation
(512MB) to a slightly less ridiculously large allocation (256MB). In practice
machines with large memory configurations are using the thash_entries setting
to limit the size of the TCP ehash _much_ lower than either of the
automatically computed values. Illustrative of the exceedingly large nature
of the automatically computed size, SGI currently recommends that customers
boot with thash_entries=2097152, which works out to a 32MB allocation. In any
case, setting hashdist=0 will allow for allocations in excess of vmalloc
limits, if so desired.
Other than the vmalloc limit, great care was taken to ensure that the size of
TCP hash allocations was not altered by this patch. Due to slightly different
computation techniques between the existing TCP code and
alloc_large_system_hash (which is now utilized), some of the magic constants
in the TCP hash allocation code were changed. On all sizes of system (128MB
through 64GB) that I had access to, the patched code preserves the previous
hash size, as long as the vmalloc limit (256MB on IA64) is not encountered.
There was concern that changing the TCP-related hashes to use vmalloc space
may adversely impact network performance. To this end the netperf set of
benchmarks was run. Some individual tests seemed to benefit slightly, some
seemed to be harmed slightly, but in all cases the average difference with and
without these patches was well within the variabilty I would see from run to
run.
The following is the overall netperf averages (30 10 second runs each) against
an older kernel with these same patches. These tests were run over loopback
as GigE results were so inconsistent run to run both with and without these
patches that they provided no meaningful comparison that I could discern. I
used the same kernel (IA64 generic) for each run, simply varying the new
"hashdist" boot parameter to turn on or off the new allocation behavior. In
all cases the thash_entries value was manually specified as discussed
previously to eliminate any variability that might result from that size
difference.
HP ZX1, hashdist=0
==================
TCP_RR = 19389
TCP_MAERTS = 6561
TCP_STREAM = 6590
TCP_CC = 9483
TCP_CRR = 8633
HP ZX1, hashdist=1
==================
TCP_RR = 19411
TCP_MAERTS = 6559
TCP_STREAM = 6584
TCP_CC = 9454
TCP_CRR = 8626
SGI Altix, hashdist=0
=====================
TCP_RR = 16871
TCP_MAERTS = 3925
TCP_STREAM = 4055
TCP_CC = 8438
TCP_CRR = 7750
SGI Altix, hashdist=1
=====================
TCP_RR = 17040
TCP_MAERTS = 3913
TCP_STREAM = 4044
TCP_CC = 8367
TCP_CRR = 7538
I believe the TCP_CC and TCP_CRR are the tests most sensitive to this
particular change. But again, I want to emphasize that even the differences
you see above are _well_ within the variability I saw from run to run of any
given test.
In addition, Jose Santos at IBM has run specSFS, which has been particularly
sensitive to TLB issues, against these patches and saw no performance
degredation (differences down in the noise).
This patch:
Modifies alloc_large_system_hash to enable the use of vmalloc to alleviate
boottime allocation imbalances on NUMA systems.
Due to limited vmalloc space on some architectures (i.e. x86), the use of
vmalloc is enabled by default only on NUMA IA64 kernels. There should be
no problem enabling this change for any other interested NUMA architecture.

[PATCH] collect page_states only from online cpus
I noticed the function __read_page_state() curiously high in a q-tools
profile of a write to a software raid0 device. Seems this is because we're
checking page_states for all possible cpus and we have NR_CPUS possible
when CONFIG_HOTPLUG_CPU=y. The default config for ia64 is now NR_CPUS=512,
so on a little 8-way box, this is a significant waste of time. The patch
below updates __read_page_state() and __get_page_state() to only count
page_state info for online cpus. To keep the stats consistent, the
page_alloc notifier is updated to move page_states off of the cpu going
offline. On my profile, this dropped __read_page_state() back into the
noise and boosted block write performance by 5% (as measured by spew -
http://spew.berlios.de).

[PATCH] mark_page_accessed() for read()s on non-page boundaries
When reading a (partial) page from disk using read(), the kernel only marks
the page as "accessed" if the read started at a page boundary. This means
that files that are accessed randomly at non-page boundaries (usually
database style files) will not be cached properly.
The patch below uses the readahead state instead. If a page is read(), it
is marked as "accessed" if the previous read() was for a different page,
whatever the offset in the page.
Testing results:
- Boot kernel with mem=128M

As expected, with the read-page-access.patch, the kernel keeps the 8 MB
testfile cached as expected, while without it, it doesn't.
So this is useful for workloads where one smallish (wrt RAM) file is read
randomly over and over again (like heavily used database indexes), while
other I/O is going on. Plain 2.6 caches those files poorly, if the app
uses plain read().

[PATCH] kill off highmem_start_page
People love to do comparisons with highmem_start_page. However, where
CONFIG_HIGHMEM=y and there is no actual highmem, there's no real page at
*highmem_start_page.
That's usually not a problem, but CONFIG_NONLINEAR is a bit more strict and
catches the bogus address tranlations.
There are about a gillion different ways to find out of a 'struct page' is
highmem or not. Why not just check page_flags? Just use PageHighMem()
wherever there used to be a highmem_start_page comparison. Then, kill off
highmem_start_page.
This removes more code than it adds, and gets rid of some nasty
#ifdefs in .c files.

[PATCH] mm: overcommit updates
Alan made overcommit mode 2 and it doesnt work at all. A process passing
the limit often does so at a moment of stack extension, and is killed by a
segfault, not better than being OOM-killed.
Another problem is that close to the edge no other processes can be
started, so that a sysadmin has problems logging in and investigating.
Below a patch that does 3 things:
(1) It reserves a reasonable amount of virtual stack space (amount
randomly chosen, no guarantees given) when the process is started, so
that the common utilities will not be killed by segfault on stack
extension.
(2) It reserves a reasonable amount of virtual memory for root, so that
root can do things when the system is out-of-memory
(3) It limits a single process to 97% of what is left, so that also an
ordinary user is able to use getty, login, bash, ps, kill and similar
things when one of her processes got out of control.
Since the current overcommit mode 2 is not really useful, I did not give
this a new number.
The patch is just for playing, not to be applied by Linus. But, Andrew, I
hope that you would be willing to put this in -mm so that people can
experiment. Of course it only does something if one sets overcommit mode
to 2.
The past month I have pressured people asking for feedback, and now have
about a dozen reports, mostly positive, one very positive.

With Ram Pai <linuxram@us.ibm.com>
- request size is now passed into page_cache_readahead. This allows the
removal of the size averaging code in the current readahead logic.
- readahead rampup is now faster (especially for larger request sizes)
- No longer "slow read path". Readahead is turn off at first random access,
turned back on at first sequential access.
- Code now handles thrashing, slowly reducing readahead window until
thrashing stops, or min size reached.
- Returned to old behavior where first access is assumed sequential only if
at offset 0.
- designed to handle larger (1M or above) window sizes efficiently

[PATCH] quota umount race fix
Fix possible races between umount and quota on/off.
Finally I decided to take a reference to vfsmount during vfs_quota_on() and
to drop it after the final cleanup in the vfs_quota_off(). This way we
should be all the time guarded against umount. This way was protected also
the old code which used filp_open() for opening quota files. I was also
thinking about other ways of protection but there would be always a window
(provided I don't want to play much with namespace locks) where
vfs_quota_on() could be called while umount() is in progress resulting in
the "Busy inodes after unmount" messages...

[PATCH] Fix of quota deadlock on pagelock: quota core
The four patches in this series fix deadlocks with quotas of pagelock (the
problem was lock inversion on PageLock and transaction start - quota code
needed to first start a transaction and then write the data which subsequently
needed acquisition of PageLock while the standard ordering - PageLock first
and transaction start later - was used e.g. by pdflush). They implement a
new way of quota access to disk: Every filesystem that would like to implement
quotas now has to provide quota_read() and quota_write() functions. These
functions must obey quota lock ordering (in particular they should not take
PageLock inside a transaction).
The first patch implements the changes in the quota core, the other three
patches implement needed functions in ext2, ext3 and reiserfs. The patch for
reiserfs also fixes several other lock inversion problems (similar as ext3
had) and implements the journaled quota functionality (which comes almost for
free after the locking fixes...).
The quota core patch makes quota support in other filesystems (except XFS
which implements everything on its own ;)) unfunctional (quotaon() will refuse
to turn on quotas on them). When the patches get reasonable wide testing and
it will seem that no major changes will be needed I can make fixes also for
the other filesystems (JFS, UDF, UFS).
This patch:
The patch implements the new way of quota io in the quota core. Every
filesystem wanting to support quotas has to provide functions quota_read()
and quota_write() obeying quota locking rules. As the writes and reads
bypass the pagecache there is some ugly stuff ensuring that userspace can
see all the data after quotaoff() (or Q_SYNC quotactl). In future I plan
to make quota files inaccessible from userspace (with the exception of
quotacheck(8) which will take care about the cache flushing and such stuff
itself) so that this synchronization stuff can be removed...
The rewrite of the quota core. Quota uses the filesystem read() and write()
functions no more to avoid possible deadlocks on PageLock. From now on every
filesystem supporting quotas must provide functions quota_read() and
quota_write() which obey the quota locking rules (e.g. they cannot acquire the
PageLock).

[PATCH] introduce fallback header
Add a temporary "fallback" header so architectures can run with the 4level
patgetables patch without modification. All architectures should be
converted to use the folding headers (include/asm-generic/pgtable-nop?d.h)

Make all architectures include the fallback header, except i386, because that
architecture has earlier been converted to use pgtable-nopmd.h under the 3

[PATCH] convert Linux to 4-level page tables
Extend the Linux MM to 4level page tables.
This is the core patch for mm/*, fs/*, include/linux/*
It breaks all architectures, which will be fixed in separate patches.
The conversion is quite straight forward. All the functions walking the page
table hierarchy have been changed to deal with another level at the top. The
additional level is called pml4.
mm/memory.c has changed a lot because it did most of the heavy lifting here.
Most of the changes here are extensions of the previous code.

[PATCH] replace clear_page_tables with clear_page_range
Rename clear_page_tables to clear_page_range. clear_page_range takes byte
ranges, and aggressively frees page table pages. Maybe useful to control
page table memory consumption on 4-level architectures (and even 3 level
ones).
Possible downsides are:
- flush_tlb_pgtables gets called more often (only a problem for sparc64
AFAIKS).
- the opportunistic "expand to fill PGDIR_SIZE hole" logic that ensures
something actually gets done under the old system is still in place.
This could sometimes make unmapping small regions more inefficient. There
are some other solutions to look at if this is the case though.

[ide] make host drivers aware of the changes made to ide_setup_pci_device{s}
- nothing clever here: the most noticeable change is the change of
returned value for (*init_setup) in struct ide_pci_device_s which
goes from void to int. Anything else is editing and checking for
errors in the output of the compiler;
- pci_disable_device() added for the error path in pci_init_sgiioc4();
- BUG() removed in amd74xx_probe(): good old printk() is enough.

[ide] propagate the error status in ide_pci_enable/ide_setup_pci_controller
- no need to overwrite the status code returned by the pci_xyz() functions;
- jump into the new century and use DMA_32BIT_MASK;
- misc cleanup in the error paths. It should not add a huge value in
ide_pci_enable() due to the FIXME comment but it should not bite too hard
either.

[ide] clean up error path in do_ide_setup_pci_device()
ide_setup_pci_controller() puts the device in a PCI enabled state.
The patch adds a small helper to balance it when things go wrong.
Actually the helper does not *exactly* balance the setup: if it can
not do a better job, ide_setup_pci_controller() may only enable some
BARS whereas the new counterpart will try to disable everything.

[ide] propagation of error code in PCI IDE setup
- Change the return value and the prototype of do_ide_setup_pci_device
Due to lack of appropriate return status code, the current clients of
do_ide_setup_pci_device() can not distinguish a failing invocation
from a successfull one. The patch modify do_ide_setup_pci_device() so
that it can propagate some of the errors from the lower layers.
- Make ide_setup_pci_device() aware of the change and propagate the news
itself. I only gave a quick sight to create_proc_ide_interfaces() (and
ide_remove_proc_entries()) but they do seem sane and it should not matter
if it fails or not.
- ide_setup_pci_devices(): mostly the same thing than ide_setup_pci_device().
do not look trivially suspect.

From: Alan Cox <alan@lxorguk.ukuu.org.uk>
Several IDE drivers return positive values as errors in the PCI setup

so the driver skips the device but still claims it and things then go
downhill.

[ARM PATCH] 2327/1: Thumb ld/st alignment fault fixups
Patch from George G. Davis
Adds support for Thumb ld/st alignment fault fixups via conversion of
Thumb ld/st instruction forms into equivalent ARM instructions and
reusing ARM alignment fault handler for Thumb instructions. This
implementation was inspired by and initially based on the algorithm
found in gdb/sim/arm/thumbemu.c.
I've backed out the silly 'T' suffix on PC in this version as requested
by RMK. At this point, I prefer to avoid making any of the other changes
discussed, e.g. dump_instr() for bad instruction cases, in order to get
the basic Thumb support change committed.
Thanks!

- DMA audio functions by Nishant Menon
- Remove references to OMAP specific serial.h
This is an updated version of ARM patch 2331/1 with extra comments
added to the omap_get_dma_src_pos() and omap_get_dma_dst_pos() functions

[PATCH] zatm fix
Repairs the breakage introduced in gcc4 fixes. Original had expanded
to
((struct zatm_dev *)(dev)->dev_data) = zatm_dev;
and that's what gcc4 had complained about (cast-as-lvalue). Proper fix is,
of course,
dev->dev_data = zatm_dev;
What we have in 2.6.10 is
dev = (struct atm_dev *)zatm_dev;
which doesn't cause complaints, but doesn't do anything good (leak + corruption
at the very least).

[ARM PATCH] 2324/1: Convert ARM proc files to use domain and pgtable manifest constants
Patch from George G. Davis
Convert ARM proc files to use manifest constants defined in pgtable.h

domain renumbering is required to implement support for ARMv6 MMU
super sections where domain 0 is implied. Although this is technically
only required for ARMv6, it seemed reasonable to clean up all proc
files while here.
I did a test build with and without this patch applied and confirmed
that all proc file binaries are unchanged when this patch is applied.

[INFINIBAND]: Add IPoIB userspace MAD support
Add a driver that provides a character special device for each
InfiniBand port. This device allows userspace to send and receive
MADs via write() and read() (with some control operations implemented
as ioctls).
All operations are 32/64 clean and have been tested with 32-bit
userspace running on a ppc64 kernel.

[INFINIBAND]: Add IPoIB (IP-over-InfiniBand) driver
Add a driver that implements the (IPoIB) IP-over-InfiniBand protocol.
This is a network device driver of type ARPHRD_INFINIBAND (and
addr_len INFINIBAND_ALEN bytes).
The ARP/ND implementation for this driver is not completely
straightforward, because InfiniBand requires an additional path lookup
be performed (through an IB-specific mechanism) after a remote
hardware address has been resolved. We are very open to suggestions
of a better way to handle this than the current implementation.
Although IB has a special multicast group join mode intended to
support IP multicast routing (non member join), no means to identify
different multicast styles has yet been determined, so all joins by
the driver are currently full member joins. We are looking for
guidance in how to solve this.
The IPoIB protocol/encapsulation is described in the Internet-Drafts

[libata] verify ATAPI DMA for a given request is OK
After some testing, it seems that some PATA host adapter (ex. pdc20275) cannot
work reliably with specific request buffer sizes under ATAPI DMA mode.
Detailed test result:
4096, 2048, 1024, 512, 256: OK
384, 257, 255, 128, 96, 64, 32: failed (irq lost)
It seems multiple of 256 bytes are the safe ATAPI DMA buffer sizes to use.
Attached please find the patch to fix the pdc2027x ATAPI DMA problem.
Changes:
1. Add a callback function "check_atapi_dma()" to ata_port_operations such that libata core
can ask the driver: "Can this command be processed in ATAPI DMA mode safely? "
when the the command is received.
2. ATAPI DMA is off by default if the callback function is not provided by the driver
If the callback function is not provided by the driver, the ATAPI DMA should be as is.
The ATAPI DMA is already controlled by dev->flags.
BTW, the patch isolates the ATAPI DMA workaround to the pdc20275 driver itself,
not impacting libata core .

[libata] PIO error handling improvement
Tested burning CD-RW with libata-dev-2.6 and cdrecord:
1. ATAPI DMA mode - tested OK
2. ATAPI PIO mode - test failed when cdrecord finishes burning and issues MODE_SELECT to the device.
After checking the log, it showed that MODE_SELECT caused ata_pio_complete() to return error.
However, the error is not handled by ata_pio_task().
Attached please find the patch for ata_pio_task() error handling for your review.
(The patch is against the libata-dev-2.6 tree. )
Changes in the patch:
1. End the PIO task when PIO_ST_IDLE state is entered
2. End the PIO task after PIO_ST_TMOUT and PIO_ST_ERR state handled by ata_pio_error()
3. Remove the first "if" statement to handle the error condition returned from
ata_pio_block(), ata_pio_complete() and ata_pio_poll().
Change #2 is not so necessary since ata_pio_error() will put the cmd to PIO_ST_IDLE state
after the error condition is handled. The change just saves a function call to queue_work().
Tested OK on on my machine with pdc20275 and ASUS CD-RW drive.

[ARM PATCH] 2264/1: Move platform-specific code out of entry-armv.S
Patch from Deepak Saxena
This patch borrows from the uclinux source where they have moved
the per-platform code for get_irqnr_and_base, disable_fiq, and
irq_prio_table out of entry-armv.S. However, instead of putting the
macros in arch/arm/mach-$(MACHINE)/entry-header.S, we just have
it in the machine's incdir. This means we don't need the extra
complexity of creating symlink at build time. The patch also removes
the irq_prio_table as a requirement for all machines and makes it
specific to IOC/IOMD machines.
This patch drastically shrinks entry-armv.S and allows us to delete
and add machines without having to touch generic code (there were two
dead machines laying around in entry-armv.S).
Tested on IXP4xx and test-built for just about every defconfig.
