[PATCH] kbuild: Improved external module support
From: Sam Ravnborg <sam@ravnborg.org>
The external module support recently introduced caused a number of problems:
- To build an external module the Module.symvers file was needed
- To create the Module.symvers file a module was required
- If Module.symvers was missing kbuild boiled out with an error
- If vmlinux was missing also the stage 2 of module build failed (make -k)
- It was not documented what was needed to actually bauild a module
The following patch addresses this by adding the following functionality:
- Always generate the Module.symvers file
- Ignore a missing Module.symvers file
- Add a new target modules_prepare, it prepares the kernel for building
external modules, and is also usefull with O=
- And it adds some more comments to Makefile.modpost, so others may follow
it with some luck
- .modpost.cmd is no longer generated
This should close all reports on issues with respect to building external
modules with current kernel - which has been identified as kernel problems.

[PATCH] SELinux ptrace race fix
From: Stephen Smalley <sds@epoch.ncsc.mil>
Looking again at the SELinux ptrace check, I believe that there is an
unrelated race due to the fact that the parent link is only updated after
releasing the task lock in ptrace_attach (and this is necessary as task lock
doesn't nest with write lock of tasklist_lock).
The patch below changes SELinux to save the tracing process' SID upon a
successful selinux_ptrace hook call and then use that SID in the ptrace check
in apply_creds in order to avoid such races. This allows us to preserve the
fine-grained process-to-process ptrace check upon exec (vs. the global
CAP_SYS_PTRACE privilege => PT_PTRACE_CAP flag used by the capability module)
while still avoiding races.

[PATCH] slab: use order 0 for vfs caches
We have interesting deadlocks when slab decides to use order-1 allocations for
ext3_inode_cache. This is because ext3_alloc_inode() needs to perform a
GFP_NOFS 1-order allocation.
Sometimes the 1-order allocation needs to free a huge number of pages (tens of
megabytes) before a 1-order grouping becomes available. But the GFP_NOFS
allocator cannot free dcache (and hence icache) due to the deadlock problems
identified in shrink_dcache_memory().
So change slab so that it will force 0-order allocations for shrinkable VFS
objects. We can handle those OK.

[PATCH] slab alignment fixes
From: Manfred Spraul <manfred@colorfullife.com>
Below is a patch that redefines the kmem_cache_alloc `align' argument:
- align not zero: use the specified alignment. I think values smaller than
sizeof(void*) will work, even on archs with strict alignment requirement (or
at least: slab shouldn't crash. Obviously the user must handle the
alignment properly).
- align zero:
* debug on: align to sizeof(void*)
* debug off, SLAB_HWCACHE_ALIGN clear: align to sizeof(void*)
* debug off, SLAB_HWCACHE_ALIGN set: align to the smaller of
- cache_line_size()
- the object size, rounded up to the next power of two.
Slab never honored cache align for tiny objects: otherwise the 32-byte
kmalloc objects would use 128 byte objects.
There is one additional point: right now slab uses ints for the bufctls.
Using short would save two bytes for each object. Initially I had used short,
but davem objected. IIRC because some archs do not handle short efficiently.
Should I allow arch overrides for the bufctls? On i386, saving two bytes
might allow a few additional anon_vma objects in each page.

[PATCH] ppc64: Move Initrd
From: Rusty Russell <rusty@rustcorp.com.au>
This patch moves the initrd when "make_room" runs out of space, rather than
stepping over it. The problem with stepping over it is that it gets copied
with the kernel when this happens, which wastes space.
Also ensures that the initrd isn't where the kernel wants to be moved to: if
it is, it gets moved out the way.

[PATCH] ppc64: make_room macro for ppc64 prom.c
From: Rusty Russell <rusty@rustcorp.com.au>
copy_device_tree calls inspect_node() which recurses to copy the Open Firmware
device tree. It just copied into memory above the kernel for about 8MB, which
can overwrite the initrd, and/or get truncated on big machines.
The real solution is to allocate memory properly for all the prom_init memory
users. However, that's quite a change. This patch introduces a "make_room"
macro which inspect_node uses to get memory. This does the same as before,
except skips over the initrd if neccessary.

[PATCH] ppc64: Make finish_device_tree use lmb_alloc, not klimit
From: Rusty Russell <rusty@rustcorp.com.au>
finish_device_tree simply allocates nodes by incrementing klimit (ie. using

needs, then use lmb_alloc to allocate that, then fill it in.
This gets rid of the only manipulation of klimit after prom_init.

[PATCH] credentials locking fix
From: Chris Wright <chrisw@osdl.org>
Contributions from:
Stephen Smalley <sds@epoch.ncsc.mil>
Andy Lutomirski <luto@stanford.edu>
During exec the LSM bprm_apply_creds() hooks may tranisition the program to a
new security context (like setuid binaries). The security context of the new
task is dependent on state such as if the task is being ptraced.
ptrace_detach() doesn't take the task_lock() when clearing task->ptrace. So
there is a race possible where a process starts off being ptraced, the
malicious ptracer detaches and if any checks agains task->ptrace are done more
than once, the results are indeterminate.
This patch ensures task_lock() is held while bprm_apply_creds() hooks are
called, keeping it safe against ptrace_attach() races. Additionally, tests
against task->ptrace (and ->fs->count, ->files->count and ->sighand->count all
of which signify potential unsafe resource sharing during a security context
transition) are done only once the results are passed down to hooks, making it
safe against ptrace_detach() races.
Additionally:
- s/must_must_not_trace_exec/unsafe_exec/
- move unsafe_exec() call above security_bprm_apply_creds() call rather than
in call for readability.
- fix dummy hook to honor the case where root is ptracing
- couple minor formatting/spelling fixes

[PATCH] Use workqueue for call_usermodehelper
From: Rusty Russell <rusty@rustcorp.com.au>
call_usermodehelper uses keventd to create a thread, guaranteeing a nice,
clean kernel thread. Unfortunately, there is a case where
call_usermodehelper is called with &bus->subsys.rwsem held (via
bus_add_driver()), but keventd could be running bus_add_device(), which is
blocked on the same lock. The result is deadlock, and it comes from using
keventd for both.
In this case, it can be fixed by using a completely independent thread for
call_usermodehelper, or an independent workqueue. Workqueues have the
infrastructure we need, so we use one.
Move EXPORT_SYMBOL while we're there, too.

[PATCH] create singlethread_workqueue()
From: Rusty Russell <rusty@rustcorp.com.au>
Workqueues are a great primitive for running things from user context from
a completely clean environment. Unfortunately, they currently insist on
creating one thread per CPU, which is overkill for many situations, so the
more generic keventd workqueue is used for these. Recently deadlocks using
keventd were demonstrated, showing that it is not suitable for all uses.
1) Clean up CPU iterators. Always a nice touch.
2) Add __create_workqueue() and create_singlethread_workqueue(),
keeping source compatibility.
3) Put workqueues in workqueue list even if !CONFIG_HOTPLUG_CPU (means
we need a lock to protect that list). Now we can tell if a wq is
single-threaded using list_empty(&wq->list).
4) For single-threaded workqueues, override CPU in queue_work,
delayed_work_timer_fn and flush_workqueue to be 0. flush_workqueue
now does redundant passes for single-threaded workqueues, but the
code remains simple.
5) Make create_workqueue_thread return the thread, so we can easily
kthread_bind for multi-threaded workqueues.
akpm fixes:

[TG3]: Fix jimbo frame PHY programming.
1. Added new workaround for 5705 to improve bit error rate.
2. Changed to use read-modify-write to set the extended packet bit in
tg3_phy_reset.
3. Removed some phy setup code in tg3_phy_probe. All of that is already
in the end of tg3_phy_reset. Writing to the phy during probe time may
contend with ASF because ASF is constantly reading phy registers to
determine the link.
4. Removed the write to phy register 0x18 in tg3_phy_copper_begin. Not
sure what it was for and it will overwrite that regsiter.

[PATCH] ia64: bug w/ shared interrupts
I just ran into a bug introduced by the most recent iosapic.c patch.
The scenario is a builtin driver is up and running happily. A module
loads for a devices that happens to share the same interrupt vector,
in this case a network driver. The module calls pci_enable_device()
as it should, which eventually lands in iosapic_enable_intr(). We
then proceed to mask the interrupt and kill the device that's already
running. As a bonus, request_interrupt() doesn't fix the problem
because we only call the startup for the interrupt handler on the
first action attached to the interrupt.
I think the best way out of this is simply to detect when an action is
already attached to a vector and leave it alone. This also prevents
interrupts from moving to other cpus (on boxes w/o irq redirection)
for no good reason.

[PATCH] don't log drive loading failures
This is an old bug that often confuses people, rightfully.
For some laptop and server type cdroms, the drives advertise themselves
as tray loading even if they are caddy-like or slot-in loaders. This
means they cannot insert the media on their own, and this generates a
5/24/00 error to START_STOP_UNIT.
This prevents the logging of such a failure, and also fixes the
generation of such a bad command in case the mech type was correctly set
by the drive.

[ARM PATCH] 1815/1: Generic DMA buffer bouncing support for ARM targets
Patch from Deepak Saxena
Latest (and hopefully last :) patch for generic DMA buffer bouncing.
- Fixed SA1111 dma_needs_bounce
- Added check for out of bounds buffers.
- Made dmabounce.c directly implement dma_* API
Note that I didn't do the following:
#ifndef CONFIG_DMABOUNCE
inline implementations of all functions
#else
extern declarations
#endif
Instead I wrapped it individual in #ifndef/#else blocks to keep the
comments in the same area as function declarations. IMHO this makes
it easier for someone to go look at the comments if they need to know
what a specific API does.

[ARM PATCH] 1825/1: abort on bad code generation with div64 in some cases
Patch from Nicolas Pitre
One case was found when the kernel is compiled with -O2 (instead of the

this. Instead of blacklisting them all unconditionally, better just abort
when a bad case occurs especially since this bad case doesn't seem to
appear with current default compiler flags. Depends on patch #1824.

[ARM PATCH] 1824/1: guard against gcc not respecting local variable register assignment
Patch from Nicolas Pitre
The recent discovery of a problem with gcc not always respecting register

especially when the code is right but silently ignored. This patch adds a
test where needed to have the assembler confirm our register selection and
fail the kernel build if the wrong registers are allocated.

somehow it passed the regression tests...)

[PATCH] pcmcia netdev ordering fixes
From: Russell King <rmk+pcmcia@arm.linux.org.uk>
This is an *untested* patch (PCMCIA people, please test) to fix
initialisation ordering issues in these network device drivers. I don't
have the hardware to be able to test these changes, although it passes a
modular build without warnings.
Andrew - it may be worth sticking these in -mm so they get some visibility
via your tree as well.
Many of these drivers were calling register_netdev() before they had
completed their initialisation.
In addition, they were calling register_netdev with the
"DEV_CONFIG_PENDING" flag still set, which prevents hotplug scripts from
bringing up the interface.
Also, we take care to ensure that link->dev is correctly set - this is used
to tell the PCMCIA release code if the netdev is currently registered (yes,
that's probably racy at present, but lets sort one problem at a time.)
I've arranged that all drivers register the netdevice as close as possible
to the end of their initialisation, copy the net device's name for cardmgr
to pass to it's network scripts, and then print out whatever information
the driver wants to.
Finally, a note about ibmtr - it seemed to assume that cardmgr wanted "tr0"
or "tr1" depending on the base address, and completely ignoring the real
device which the netdev layer allocated it. I've assumed that this is
wrong (since the netdev name is used in printk messages), and changed it to
behave the same as the other drivers.

[PATCH] atmel wireless update
Fixes to avoid problems when the driver shares an interrupt. These were
caused because the ISR cannot determine the status of the chip without
changing its state and the driver was only disabling the interrupts from
the card during some critical regions. An interrupt originating from
another device at the wrong moment could run the ISR and corrupt chip
state. Fixed by blocking interupts in the processor in critical regions
and never checking the chip interrupt status before the driver is fully
up.
Added the ability to override the Regulatory Domain stored in ROM. The
following command achieves this
iwpriv <interface> regdomain <domain>
vaild domains are USA,Canada,Europe,Spain,France,MKK,MKK1,Israel
The current regulatory domain affects which radio channels are available
for use.

[PATCH] removal of MOD_{INC,DEC}_USE_COUNT in ide-cs.c
From: Pavel Roskin <proski@gnu.org>
The "ide-cs" module cannot be unloaded because it uses obsolete
MOD_INC_USE_COUNT and MOD_DEC_USE_COUNT macros. In fact, they are not
needed in ide-cs.c in 2.6 kernels. The generic PCMCIA code already
increases use count for every device served by the driver, so it's
impossible to unload the ide-cs driver while it's in use.
I was told that the removal of IDE interfaces may be unsafe in 2.6
kernels. However, MOD_INC_USE_COUNT only prevents removal of the module,
not the interface. It's also the first obstacle, albeit a trivial one,
for anybody debugging those problems (i.e. loading a modified module
requires "rmmod -f" or reboot to unload the old version).

[PATCH] i386 hugetlb tlb correction
From: William Lee Irwin III <wli@holomorphy.com>
i386 does hardware interpretation of pagetables, so pte_clear() can't be
used on present ptes, as it sets the upper half of the hugepte prior to
setting the lower half (which includes the valid bit). i.e. there is a
window where having a hugepage mapped at 56GB and doing pte_clear() in
unmap_hugepage_range() allows other threads of the process to see a
hugepage at 0 in place of the original hugepage at 56GB.
This patch corrects the situation by using ptep_get_and_clear(), which
clears the lower word of the pte prior to clearing the upper word.
There is another nasty where huge_page_release() needs to wait for TLB
flushes before returning the hugepages to the free pool, analogous to the
issue tlb_remove_page() and tlb_flush_mm() repair.

[PATCH] selinux: remove hardcoded policy assumption from get_user_sids() logic
From: Stephen Smalley <sds@epoch.ncsc.mil>
This patch removes a hardcoded policy assumption from the get_user_sids logic
in the SELinux module that was preventing it from returning contexts that had
the same type as the caller even if the policy allowed such a transition. The
assumption is not valid for all policies, and can be handled via policy
configuration and userspace rather than hardcoding it in the module logic.

[PATCH] selinux: add runtime disable
From: Stephen Smalley <sds@epoch.ncsc.mil>
This patch adds a kernel configuration option that enables writing to a new

to initial policy load. SELinux will then remain disabled until next boot.
This option is similar to the selinux=0 boot parameter, but is to support
runtime disabling of SELinux, e.g. from /sbin/init, for portability across
platforms where boot parameters are difficult to employ (based on feedback by
Jeremy Katz).

[PATCH] selinux: change context_to_sid handling for no-policy case
From: Stephen Smalley <sds@epoch.ncsc.mil>
This patch changes the behavior of security_context_to_sid in the no-policy
case so that it simply accepts all contexts and maps them to the kernel SID
rather than rejecting anything other than an initial SID. The change avoids
error conditions when using SELinux in permissive/no-policy mode, so that any
file contexts left on disk from prior use of SELinux with a policy will not

[PATCH] lockfs - dm bits
From: Christoph Hellwig <hch@lst.de>
This patch makes the device mapper use the new freeze_bdev/thaw_bdev
interface. Extracted from Chris Mason's patch.

[PATCH] lockfs - xfs bits
From: Christoph Hellwig <hch@lst.de>
Remove all the code now in the VFS, make XFS's freeze ioctls use the new
infastructure and reorganize some code.
This code needs some work so the source files shared with 2.4 aren't
exposed to the new VFS interfaces directly. You'll get an update once this
has been discussed with the other XFS developers and is implemented. Note
that the current patch works fine and I wouldn't complain if it gets into
Linus' tree as-is.

[PATCH] lockfs: reiserfs fix
From: Chris Mason <mason@suse.com>
reiserfs_write_super_lockfs() is supposed to wait for the transaction to
commit.

[PATCH] lockfs - vfs bits
From: Christoph Hellwig <hch@lst.de>
These are the generic lockfs bits. Basically it takes the XFS freezing
statemachine into the VFS. It's all behind the kernel-doc documented
freeze_bdev and thaw_bdev interfaces.
Based on an older patch from Chris Mason.

[PATCH] remove amd7xx_tco
From: Zwane Mwaikambo <zwane@linuxpower.ca>
We've had trouble with this driver, it appears to work but the hardware
never does the final reboot. I have yet to come across someone with a
board which works and don't have personal access to one. So how about
scrapping the whole thing.

[PATCH] Call populate_rootfs later in boot
populate_rootfs() is called rather early - before we've called init_idle().
But populate_rootfs() does file I/O, which involves calls to cond_resched(),
and downing of semaphores, etc. If it scheules, the scheduler emits
scheduling-while-atomic warnings and sometimes oopses.
So run populate_rootfs() later, after the scheduler is all set up.

[PATCH] ext3 avoid writing kernel memory to disk
From: Marc-Christian Petersen <m.c.p@kernel.linux-systeme.com>
Solar Designer discovered an information leak in the ext3 code of Linux.
In a worst case an attacker could read sensitive data such as cryptographic
keys which would otherwise never hit disk media. Theodore Ts'o developed a
correction for this.

[PATCH] compute_creds race
From: Andy Lutomirski <luto@myrealbox.com>
Fixes from me, Olaf Dietsche <olaf+list.linux-kernel@olafdietsche.de>
In fs/exec.c, compute_creds does:
task_lock(current);
if (bprm->e_uid != current->uid || bprm->e_gid != current->gid) {
current->mm->dumpable = 0;
if (must_not_trace_exec(current)
|| atomic_read(¤t->fs->count) > 1
|| atomic_read(¤t->files->count) > 1
|| atomic_read(¤t->sighand->count) > 1) {
if(!capable(CAP_SETUID)) {
bprm->e_uid = current->uid;
bprm->e_gid = current->gid;
}
}
}
current->suid = current->euid = current->fsuid = bprm->e_uid;
current->sgid = current->egid = current->fsgid = bprm->e_gid;
task_unlock(current);
security_bprm_compute_creds(bprm);
I assume the task_lock is to prevent another process (on SMP or preempt)
from ptracing the execing process between the check and the assignment. If
that's the concern then the fact that the lock is dropped before the call
to security_brpm_compute_creds means that, if security_bprm_compute_creds
does anything interesting, there's a race.
For my (nearly complete) caps patch, I obviously need to fix this. But I
think it may be exploitable now. Suppose there are two processes, A (the
malicious code) and B (which uses exec). B starts out unprivileged (A and
B have, e.g., uid and euid = 500).
1. A ptraces B.
2. B calls exec on some setuid-root program.
3. in cap_bprm_set_security, B sets bprm->cap_permitted to the full
set.
4. B gets to compute_creds in exec.c, calls task_lock, and does not
change its uid.
5. B calls task_unlock.
6. A detaches from B (on preempt or SMP).
7. B gets to task_lock in cap_bprm_compute_creds, changes its
capabilities, and returns from compute_creds into load_elf_binary.
8. load_elf_binary calls create_elf_tables (line 852 in 2.6.5-mm1),
which calls cap_bprm_secureexec (through LSM), which returns false (!).
9. exec finishes.
The setuid program is now running with uid=euid=500 but full permitted
capabilities. There are two (or three) ways to effectively get local root
now:
1. IIRC, linux 2.4 doesn't check capabilities in ptrace, so A could
just ptrace B again.
2. LD_PRELOAD.
3. There are probably programs that will misbehave on their own under
these circumstances.
Is there some reason why this is not doable?
The patch renames bprm_compute_creds to bprm_apply_creds and moves all uid
logic into the hook, where the test and the resulting modification can both
happen under task_lock().
This way, out-of-tree LSMs will fail to compile instead of malfunctioning.
It should also make life easier for LSMs and will certainly make it easier
for me to finish the cap patch.

[PATCH] Fix nfsroot option handling
From: Trond Myklebust <trond.myklebust@fys.uio.no>
The following patch fixes up a number of bugs in the NFSroot parser
rewrite from patchset
trond.myklebust@fys.uio.no|ChangeSet|20040411182341|00938
It also ensures that NFSroot mount options are consistent with the userland
"mount" program.

[PATCH] Add missing __initdata
One of the stack size optimizations introduced a new static variable in
a function marked with __init. But the variable is not marked
appropriately and so 1k of data is never freed.
