[PATCH] writepages drops bh on not uptodate page
I think I understood why some ext2 fs corruption still happens even after
the last i_size fix.
what happened I believe is that the writepages layer got a not a fully
uptodate page (in turn with bh mapped on top of it), and then right before
unlocking the page and entering the writeback mode, it freed all the bh.
Without bh a not uptodate page will trigger a full readpage from disk, that
overwrites the pagecache before the multi-bio gets submitted, generating fs
corruption.
I believe the below patch should fix it (untested) against kernel CVS.
The testcases developed by Kurt showed the pagecache being overwritten with
on-disk data at block offsets, and Chris as well was wondering about races
between wait_on_page_writeback and readpage. the below fix just explains
everything we've seen since not-fully-uptodate pages must have always bh on
them and the below patch enforces just that invariant, and it should fix
our pagecache-overwritten-by-disk-data problem.

[PATCH] Add documentation about /proc/sys/vm/laptop_mode to various docs.
From: Bart Samwel <bart@samwel.tk>
A bunch of small laptop mode updates:
* Mention the laptop_mode and block_dump sysctls in the relevant docs,
referring to the laptop-mode.txt. Improve description of what the
laptop_mode knob means (i.e. seconds between last I/O and automatic
sync).
* Document the most relevant config file options.
* Change the installation instructions in the laptop mode doc to describe
the ACPI-bound version first, because this is the easiest. Explain
the non-ACPI version afterwards. Added a reference to my "packaged
version" of the scripts.
* Move the setting of hdparm and cpu frequency out of the ACPI script
and into the core laptop mode script. Add config option DO_HD to
enable hdparm. Add config setting HD to set device to do hdparm on.
Rename Dax's CPU_MANAGE to DO_CPU, with 0/1 instead of yes/no, to
improve consistency.
* Fix a problem where the root filesystem wouln't be remounted when
/etc/mtab listed its type as "unknown". Deduce the type of "unknown"
filesystems from /etc/fstab.
This depends on the patch that adds config files, which was submitted

[PATCH] fix readahead breakage for sequential after random reads
Current readahead logic is broken when a random read pattern is followed by
a long sequential read. The cause is that on a window miss ra->next_size
is set to ra->average, but ra->average is only updated at the end of a
sequence, so window size will remain 1 until the end of the sequential
read.
This patch fixes this by taking the current sequence length into account
(code taken from towards end of page_cache_readahead()), and also setting
ra->average to a decent value in handle_ra_miss() when sequential access is
detected.

[PATCH] ipmi_msghandler module load failure fix
On a 2.6.7 kernel, when I try to modprobe ipmi_msghandler, it fails to load
with following message:
FATAL: Error inserting ipmi_msghandler (/lib/modules/2.6.7/kernel/drivers/char/ipmi/ipmi_msghandler.ko): Invalid module format
And there is an error message in dmesg:
ipmi_msghandler: init symbol 0xa000000200058080 used in module code at a000000200031b32
What I have been able to determine is that ipmi_msghandler.c defines
ipmi_init_msghandler() as the module_init() routine and then it also calls
ipmi_init_msghandler() diretcly from couple of other places. This does not
seem to be okay in 2.6.7 kernel. I was able to fix this by defining a new
module_init routine which in turn calls ipmi_init_msghandler(). I also
removed __init from ipmi_init_msghandler() since it gets called from
ipmi_open() on an open of the ipmi device file. So I would think we want
to keep ipmi_init_msghandler() around even after initialization.

[PATCH] Make get_user_pages() work again for ia64 gate area
Changeset
roland@redhat.com[torvalds]|ChangeSet|20040624165002|30880
inadvertently broke ia64 because the patch assumed that pgd_offset_k() is
just an optimization of pgd_offset(), which it is not. This patch fixes
the problem by introducing pgd_offset_gate(). On architectures on which
the gate area lives in the user's address-space, this should be aliased to
pgd_offset() and on architectures on which the gate area lives in the
kernel-mapped segment, this should be aliased to pgd_offset_k().
This bug was found and tracked down by Peter Chubb.

headers for partner info gathering and vterm connection and termination
interfaces.
* arch/ppc64/kernel/Makefile
Added build directive for hvcserver.o when HVCS is configured.
* arch/ppc64/kernel/hvconsole.c
Exported hvc_put_chars() and hvc_get_chars() for use by HVCS.
* arch/ppc64/kernel/hvcserver.c
Body of hvcserver module which accompanies the hvcs module and provides
ppc64 architecture firmware calls for use by HVCS. This file provides
function bodies for partner info gathering and vterm connection and
termination interfaces.
* drivers/char/Kconfig
Added CONFIG_HVCS option for both built-in version and module version
of hvcs.
* drivers/char/Makefile
Added build directive for hvcs.o when CONFIG_HVCS is configured.
* drivers/char/hvcs.c
This is the device driver for the IBM Hypervisor Virtual Console
Server, "hvcs". The IBM hvcs provides a tty driver interface to allow
Linux user space applications access to the system consoles of logically
partitioned operating systems, e.g. Linux, running on the same
partitioned Power5 ppc64 system. Physical hardware consoles per
partition are not practical on this hardware so system consoles are
accessed by this driver using inter-partition firmware interfaces to
virtual terminal devices.
* Documentation/powerpc/hvcs.txt
HVCS installation and usage documentation.
Thanks everyone for all the help with this driver [Andrew Morton, Paul
Mackerras, Ben Herrenschmidt, Dave Hansen, Paul Mackerras, Dave Boutcher,
Hollis Blanchard, Santiago Leon, Brian King, Randy Dunlap].

[PATCH] ppc64: Fix RAS irq handlers
On pSeries systems, the firmware tells us a list of interrupt numbers
that we should enable in order to detect various error conditions.
When we get one of these interrupts we are supposed to call the
firmware, which will work out and tell us what the error was and
possibly also fix it.
We were not correctly parsing the property values that tell us which
interrupts need to be handled in this fashion. This patch fixes it.
It exports prom_n_intr_cells from prom.c since that is needed to do
the parsing properly.

On Power4 and earlier hardware there is no need to clear the CPPR (see RPAp
479 section 18.5.4.7.2 for what little info there is on the CPPR) when
stopping a cpu. On hardware that uses Power5 an undocumented change has
been made that requires the CPPR to be cleared if an isolate is to be done
on the stopped cpu. So the following patch lets cpu hotplug work on the
recent hardware.
I sent this patch to the ppc64-dev list back in mid April and Suse picked

[PATCH] page align emergency stack
The PPC64 ABI requires the stack to be 128 byte aligned (and that can
become important if AltiVec registers are saved there). In the kernel,
that's usually dealt with by the fact that the stack has a page
more-or-less to itself. However, the emergency stacks (used in SMP bringup
and when we detect a bad stack pointer) aren't necessarily page aligned, or
anything aligned for that matter. This patch applies the necessary
alignement constraint to them.

[PATCH] swapoff mmap_sem deadlock
Updating the mm lock ordering documentation drew attention to the fact that
we were wrong to blithely add down_read(&mm->mmap_sem) to swapoff's
unuse_process, while it holds swapcache page lock: not very likely, but it
could deadlock against, say, mlock faulting a page back in from swap.
But it looks like these days it's safe to drop and reacquire page lock if
down_read_trylock fails: the page lock is held to stop try_to_unmap
unmapping the page's ptes as fast as try_to_unuse is mapping them back in;
but the recent fix for get_user_pages works to prevent that too.

[PATCH] install_page vs. vmtruncate
BK is still missing one piece for Oleg's install_page/vmtruncate races.
Oleg didn't explicitly ACK this, but I think he did implicitly: Oleg?
The previous patch to install_page, returning an error if !page_mapping
once page_table_lock is held, is not enough to guard against vmtruncate.
When unmap_mapping_range already did this vma, but truncate_inode_pages has
not yet done this page, page->mapping will still be set, but we must now
refrain from inserting the page into the page table.
Could check truncate_count, but that would need caller to read and pass it
down. Instead, recheck page->index against i_size, which is updated before
unmap_mapping_range. Better check page->mapping too: not really necessary,
but it's accidental that index is left when mapping is reset.
Also, callers are expecting -EINVAL for beyond end of file, not -EAGAIN.

[PATCH] selinux: fix clearing of new personality bit on security transitions
This patch moves the clearing of the new personality bit from
selinux_bprm_apply_creds (called from compute_creds) to
selinux_bprm_set_security (called from prepare_binprm). This ensures that the
bit is cleared at the same point in exec processing as for setuid/setgid

Hopefully fixes the free-of-a-freed-page BUG caused during CDRW writing.

I have left-out the part about changing state->card to a

somewhat pervasive and I would prefer to make those changes in a separate

[sound/oss i810] add MMIO DSP support
Enclosed is a patch for the i810_audio OSS driver to support using
memory-mapped I/O for those chipsets that support it.
o Added a family of macros -- I810_IOREADx() and I810_IOWRITEx() -- that
key off the existing card->use_mmio flag to select between using readx/writex
or inx/outx for I/O operations.
o Converted existing inx/outx invocations to use
I810_IOREADx/I810_IOWRITEx instead.
o Changed GET_CIV(), GET_LVI, and CIV_TO_LVI() not only to use
I810_IOREADx/I810_IOWRITEx but also to take "card" (i.e. struct i810_card)
paramter.
o Removed check for "Pure MMIO interfaces" in i810_probe() -- replaced w/
(relocated) check for no I/O resources available.

among other things there are

That breaks quite a few drivers that should otherwise work on ppc. SR...
and LR were never used by ppc code; commented out in reg.h (note that
they are just aliases for SPRN_SR... and SPRN_LR). RPA commented out and
its instances in ppc code (all four of them) replaced with SPRN_RPA. Ditto
for DEC. The rest of the offenders (DAR and PVR) are left alone for now and
#undef'ed in drivers in question.
We probably want to rip all these guys out of reg.h and convert ppc users
to SPRN_... forms - file ends up included in alot of places and namespace
pollution like that is a Bad Thing(tm).

but screwed it up. Fixed.
b) au88x0 relied on char being signed in non-trivial ways. On ppc it's
not true. Fixed by explicit use of s8 (which is what that code really
wants).

[PATCH] NX: allow architectures to select legacy mode dynamically
On some platforms, you'll want to support READ_IMPLIES_EXEC differently
depending on personality (e.g, native binary vs. x86 binary).
This supports that (and makes the code more readable while at it) by
replacing the old architecture-specific fixed LEGACY_BINARIES macro
define with a architecture-specific "elf_read_implies_exec_binary()"
helper function.
For now, x86 is the only user, and sets the "read implies exec" bit for
legacy apps. ia64 and x86-64 are likely to want to do their own thing.

Simple enhancement to netem packet scheduler that makes it classful so

[PATCH] ia64: sn2 requires a 3.40 or better PROM
The SGI 3.40 PROM includes a fix for the move of the init_task to
region 5, so specify that in sn_sal.h. Unfortunately, the check for
the minimum required version happens *after* the hang/MCA that is
symptomatic of the bug, so this message also acts as an announcement
of the requirement.

[PATCH] ia64: update sn2_defconfig to include new console
Now that Linus' tree has the new sn2 console driver, make sn2_defconfig enable
it by default. The device is major 204, minor 40. Note that you'll probably
have to update your elilo.conf and inittab to use the new driver, as it's
called ttySG0 rather than ttyS0.

[PATCH] NX: clean up legacy binary support
This cleans up legacy x86 binary support by introducing a new
personality bit: READ_IMPLIES_EXEC, and implements Linus' suggestion to
add the PROT_EXEC bit on the two affected syscall entry places,
sys_mprotect() and sys_mmap(). If this bit is set then PROT_READ will
also add the PROT_EXEC bit - as expected by legacy x86 binaries. The
ELF loader will automatically set this bit when it encounters a legacy
binary.
This approach avoids the problems the previous ->def_flags solution
caused. In particular this patch fixes the PROT_NONE problem in a
cleaner way (http://lkml.org/lkml/2004/7/12/227), and it should fix the
ia64 PROT_EXEC problem reported by David Mosberger. Also,
mprotect(PROT_READ) done by legacy binaries will do the right thing as
well.
the details:
- the personality bit is added to the personality mask upon exec(),
within the ELF loader, but is not cleared (see the exceptions below).
This means that if an environment that already has the bit exec()s a
new-style binary it will still get the old behavior.
- one exception are setuid/setgid binaries: these will reset the
bit - thus local attackers cannot manually set the bit and circumvent
NX protection. Legacy setuid binaries will still get the bit through
the ELF loader. This gives us maximum flexibility in shaping
compatibility environments.
- selinux also clears the bit when switching SIDs via exec().
- x86 is the only arch making use of READ_IMPLIES_EXEC currently. Other
arches will have the pre-NX-patch protection setup they always had.
I have booted an old distro [RH 7.2] and two new PT_GNU_STACK distros
[SuSE 9.2 and FC2] on an NX-capable CPU - they work just fine and all
the mapping details are right. I've checked the PROT_NONE test-utility
as well and it works as expected. I have checked various setuid
scenarios as well involving legacy and new-style binaries.
an improved setarch utility can be used to set the personality bit
manually:
http://redhat.com/~mingo/nx-patches/setarch-1.4-3.tar.gz
the new '-X' flag does it, e.g.:
./setarch -X linux /bin/cat /proc/self/maps
will trigger the old protection layout even on a new distro.

[PATCH] pmac_zilog: serial minors taken failure path fix
I've tracked down the core issue giving me the oops wrt pmac_zilog.
When you have two serial drivers, (e.g. 8250 and PMAC_ZILOG) they both say
"I want to reserve X ports starting with major TTY_MAJOR and minor 64".
By the time pmac_zilog gets there, the ports it requests are already
reserved. Unfortunately, init_pmz() doesn't check for pmz_register()
failure, and so it merrily goes on to register the half-initialized
pmac_zilog driver with the power management subsystem.
This path provides a proper failure path.
Also:
Restore ppc configs now that I know people use AT Keyboards on CHRP and PReP
machines, and the zilog driver is no longer Oops'ing.
