[PATCH] isofs fixes
This fixes two things.
On the one hand we have the old "cruft" mount option, that sometimes was
enabled automatically, for ridiculously large files or CDROMs. But what
was ridiculous ten years ago, no longer is. So, only decide that
something is cruft when the user said so.
On the other hand, sometimes we get negative sizes. That is caused by
assignments inode->i_size = isonum_733(), where the latter was declared
integer. I made it unsigned int, as the standard also does.
(Someone with problems replied:
>> Could you test the below?
> Ok I did, the patch seems to work great! Thanks!

[PATCH] symlink 1/9: infrastructure and explanation
This patch-kit gets past the limit on nested symlinks, without
incompatible API changes _and_ with killing code duplication in most of
the readlink/follow_link pairs. And no, it's not the old ->getlink()
crap - procfs et.al. are not special-cased there.
Here's how it works:
* ->follow_link() still does what it used to do - replaces
vfsmount/dentry in the nameidata it got from caller. However, it can
also leave a pathname to be resolved by caller.
* we add an array of char * into nameidata; we always work with
nd->saved_names[current->link_count]. nd_set_link() sets it,
nd_get_link() returns it.
* callers of ->follow_link() (all two of them) check if ->follow_link()
had left us something to do. If it had (return value was zero and
nd_get_link() is non-NULL), they do __vfs_follow_link() on that name.
Then they call a new method (->put_link()) that frees whatever has to
be freed, etc.
Note that absolute majority of symlinks have "resolve a pathname" as
part of their ->follow_link(); they can do something else and some don't
do that at all, but having that pathname resolution is very, very
common.
With that change we allow them to shift pathname resolution part to
caller. They don't have to - it's perfectly OK to do all work in
->follow_link(). However, leaving the pathname resolution to caller
will
a) exclude foo_follow_link() stack frame from the picture
b) kill 2 stack frames - all callers are in fs/namei.c
and they can use inlined variant of vfs_follow_link().
That reduction of stack use is enough to push the limit on nested
symlinks from 5 to 8 (actually, even beyond that, but since 8 is common
for other Unices it will do fine).
For those who have "pure" ->follow_link() (i.e. "find a string that
would be symlink contents and say nd_set_link(nd, string)") we also get
a common helper implementing ->readlink() - it just calls
->follow_link() on a dummy nameidata, calls vfs_readlink() on result of
nd_get_link() and does ->put_link(). Using (or not using) it is up to
filesystem; it's a helper that can be used as a ->readlink() for many
filesystems, not a reimplementation of sys_readlink(). However, that's
_MANY_ filesystems - practically all of them.
Note that we don't put any crap like "if this is a normal symlink, do
this; otherwise call ->follow_link() and let it do its magic" into
callers - all symlinks are handled the same way. Which was the main
problem with getlink proposal back then.
That covers almost everything; the only cases left are nfs, ncpfs and
cifs. Those will go later - we are backwards compatible, so it's not a
problem.
First patch: infrastructure - helpers allowing ->follow_link() to leave
a pathname to be traversed by caller + corresponding code in callers.

[PATCH] ppc64: Fix booting on LPAR machines with more than 1 CPU
The exception rewrite contains a small bug that prevents bring up of CPUs
on logically partitioned machines.
The kernel is trying to zero the backlink on the new stack while running
with relocation disabled, which potentially cause it to try to access an
address outside of the region allowed in real mode. This seem to be a

[PATCH] Better memset
Anton noticed in some traces that we were spending an awfully long time
doing a memset. The ppc64 memset is basically unchanged from the ppc32
version, and it only does 4-byte stores and doesn't unroll the loop.
Here's a memset that performs a bit better.
I have been using it for 3 weeks now, and Anton has tested it on a
variety of machines, without problems.

[PATCH] ppc64: clean up prom.c and related files
Somebody back in the mists of time decided that call_prom and rtas_call
should return longs even though both of those bits of firmware run in
32-bit mode and produce a 32-bit result. To make life more interesting,
the 32-bit result gets zero-extended to 64 bits, which makes checking
for a -1 return value more complicated than it should be.
This patch changes call_prom and rtas_call to return an int, and makes
the corresponding changes to use ints for the variables used to hold
those return values.
While I was doing this I finally got annoyed enough with the strings of
prom_print() and prom_print_hex() calls that we do to write a simple
prom_printf. I deliberately didn't use snprintf because the execution
environment is weird at this point - we aren't running at the address we
are linked at just yet - and I didn't want to inflict that on any code
outside this file. I also did a prom_debug() macro, which eliminated a
few ifdefs.
There are also a bunch of other minor cleanups. This patch makes very
few algorithmic changes but does get rid of a lot of casts. :)
I have been running with this patch for a couple of weeks, and Anton has
tested it too.

[PATCH] fix x86-64 ptrace access to 32-bit vsyscall page
When I made get_user_pages support looking up a pte for the "gate" area, I
assumed it would be part of the kernel's fixed mappings. On x86-64 running
a 32-bit task, the 32-bit vsyscall DSO page still has no vma but has its
pte allocated in the user mm in the normal fashion. This patch makes it
use the generic page-table lookup calls rather than the shortcuts.
With this, ptrace on x86-64 can access a 32-bit process's vsyscall page.
The behavior on x86 is unchanged.

[PATCH] hugetlb.c - fix try_to_free_low()
From: "Chen, Kenneth W" <kenneth.w.chen@intel.com>
Turn on CONFIG_HIGHMEM and CONFIG_HUGETLBFS. Try to config the hugetlb
pool:
[root@quokka]# echo 100 > /proc/sys/vm/nr_hugepages
[root@quokka]# grep HugePage /proc/meminfo
HugePages_Total: 100
HugePages_Free: 100
[root@quokka]# echo 20 > /proc/sys/vm/nr_hugepages
[root@quokka]# grep HugePage /proc/meminfo
HugePages_Total: 0
HugePages_Free: 0
[root@quokka]# echo 100 > /proc/sys/vm/nr_hugepages
[root@quokka]# grep HugePage /proc/meminfo
HugePages_Total: 100
HugePages_Free: 100
[root@quokka]# echo 0 > /proc/sys/vm/nr_hugepages
[root@quokka]# grep HugePage /proc/meminfo
HugePages_Total: 31
HugePages_Free: 31
The argument "count" passed to try_to_free_low() is the config parameter
for desired hugetlb page pool size. But the implementation took that input
argument as number of pages to free. It also decrement the config
parameter as well. All give random behavior depend on how many hugetlb
pages are in normal/highmem zone.
A two line fix in try_to_free_low() would be:
- if (!--count)
- return 0;
+ if (count >= nr_huge_pages)
+ return count;
But more appropriately, that function shouldn't return anything.

Being able to recover the configuration from a kernel is very useful and it

keep two copies of the original .config in the kernel. One in plain text
and one gzip compressed. This is not optimal.
This patch removes the plain text version of the configuration and updates
the extraction tools to locate and use the gzip'd version of the file.
This has the added bonus of providing us with the exact same results in
both cases, the original .config; including the comments.

[PATCH] cirrusfb: major update
From: David Eger <eger@havoc.gtf.org>
This patch brings the cirrusfb driver up to date with 2.6. cirrusfb has
suffered bit rot like you wouldn't believe (last updated... 2.3.x era?).
The driver will now compile again, and you can change to a high resolution
text mode with stty. Known defects: doesn't play nice with X, nor fbset.
C = Cosmetic change
L = Logical change
A = API change
W = register Writing change
(1-CA) fb_info and cirrusfb_info:
- mostly cosmetic, but a lot less confusing, and no more nasty casting.
It used to be stylish to embed struct fb_info_gen (now struct fb_info)
as the first member of struct clgenfb_info (now struct cirrusfb_info),
and then you'd cast to the deisred struct.
Now we pass the size of our data structure to framebuffer_alloc(),
and we make fb_info and cirrusfb_info reference each other with
pointers (as in radeonfb).
In the old code, there two declarations were common:
clgenfb_info *fb_info;
clgenfb_info *info;
since there's also a 'struct fb_info' now, I found this really confusing,
and unified usage as:
cirrusfb_info *cinfo;
fb_info *info;
This accounts for a lot of the search and replace cosmetic upgrade.
(2-A) All of the FB knowledge of FB internals is gone in 2.6
(3-LW) revised maxclock numbers (cirrusfb_board_info_rec.maxclock[5])
In my quest to get fbset to work, I borrowed some maxclock data
from the X.Org tree for various chipsets. It didn't really seem
to help. oh well.
(3-LA) upgraded PCI registration
Instead of doing PCI walking from the driver, we hand off a
pci_device_id table to the PCI subsystem and just get called when
it finds a relevant board.
(4-L) striking lots of __init and __initdata specifiers
I was running into some things not working when I moved the call to
init_vgachip() from the driver registration to set_par(). I thought
perhaps this was due to some things being marked __init accidentally
so I axed said annotations. Turns out it was something else. See 5.
(5-LA) delayed chip initialization, nasty double-set_par() pseudo-bug
Tony says that the fb drivers shouldn't do any chipset initialization
until they get a set_par() call. This way, fb modules can be safely
unloaded if no one gets around to using them, and the vga_con -> fbcon
hand off is smoother, as fbcon can still grab the back-scroll data from
vga_con...
In any case, moving the calls to init_vgachip() and fbgen_do_set_var()
from driver initialization to set_par() revealed that the cirrus

[PATCH] reduce function inlining in slab.c
From: Manfred Spraul <manfred@colorfullife.com>
slab.c contains too many inline functions:
- some functions that are not performance critical were inlined. Waste
of text size.
- The debug code relies on __builtin_return_address(0) to keep track of
the callers. According to rmk, gcc didn't inline some functions as
expected and that resulted in useless debug output. This was probably
caused by the large debug-only inline functions.
The attached patche removes most inline functions:
- the empty on release/huge on debug inline functions were replaced with
empty macros on release/normal functions on debug.
- spurious inline statements were removed.
The code is down to 6 inline functions: three one-liners for struct
abstractions, one for a might_sleep_if test and two for the performance
critical __cache_alloc / __cache_free functions.
Note: If an embedded arch wants to save a few bytes by uninlining
__cache_{free,alloc}: The right way to do that is to fold the functions
into kmem_cache_xy and then replace kmalloc with
kmem_cache_alloc(kmem_find_general_cachep(),).

Reversing the patches that made all caches hw cacheline aligned had an
unintended side effect on the kmalloc caches: Before they had the
SLAB_HWCACHE_ALIGN flag set, now it's clear. This breaks one sgi driver -
it expects aligned caches. Additionally I think it's the right thing to
do: It costs virtually nothing (the caches are power-of-two sized) and
could reduce false sharing.

[PATCH] tweak the buddy allocator for better I/O merging
From: William Lee Irwin III <wli@holomorphy.com>
Based on Arjan van de Ven's idea, with guidance and testing from James
Bottomley.
The physical ordering of pages delivered to the IO subsystem is strongly
related to the order in which fragments are subdivided from larger blocks
of memory tracked by the page allocator.
Consider a single MAX_ORDER block of memory in isolation acted on by a
sequence of order 0 allocations in an otherwise empty buddy system.
Subdividing the block beginning at the highest addresses will yield all the
pages of the block in reverse, and subdividing the block begining at the
lowest addresses will yield all the pages of the block in physical address
order.
Empirical tests demonstrate this ordering is preserved, and that changing
the order of subdivision so that the lowest page is split off first
resolves the sglist merging difficulties encountered by driver authors at
Adaptec and others in James Bottomley's testing.
James found that before this patch, there were 40 merges out of about 32K
segments. Afterward, there were 24007 merges out of 19513 segments, for a
merge rate of about 55%. Merges of 128 segments, the maximum allowed, were
observed afterward, where beforehand they never occurred. It also improves
dbench on my workstation and works fine there.

[PATCH] vm: vfs shrinkage tuning
Some people want the dentry and inode caches shrink harder, others want them
shrunk more reluctantly.
The patch adds /proc/sys/vm/vfs_cache_pressure, which tunes the vfs cache
versus pagecache scanning pressure.
- at vfs_cache_pressure=0 we don't shrink dcache and icache at all.
- at vfs_cache_pressure=100 there is no change in behaviour.
- at vfs_cache_pressure > 100 we reclaim dentries and inodes harder.
The number of megabytes of slab left after a slocate.cron on my 256MB test
box:
vfs_cache_pressure=100000 33480
vfs_cache_pressure=10000 61996
vfs_cache_pressure=1000 104056
vfs_cache_pressure=200 166340
vfs_cache_pressure=100 190200
vfs_cache_pressure=50 206168
Of course, this just left more directory and inode pagecache behind instead of
vfs cache. Interestingly, on this machine the entire slocate run fits into
pagecache, but not into VFS caches.

[PATCH] vmscan.c scan rate fixes
We've been futzing with the scan rates of the inactive and active lists far
too much, and it's still not right (Anton reports interrupt-off times of over
a second).
- We have this logic in there from 2.4.early (at least) which tries to keep
the inactive list 1/3rd the size of the active list. Or something.
I really cannot see any logic behind this, so toss it out and change the
arithmetic in there so that all pages on both lists have equal scan rates.
- Chunk the work up so we never hold interrupts off for more that 32 pages
worth of scanning.
- Make the per-zone scan-count accumulators unsigned long rather than
atomic_t.
Mainly because atomic_t's could conceivably overflow, but also because
access to these counters is racy-by-design anyway.

The following patch makes irqaction's ->mask a cpumask as it was intended
to be and wraps up the rest of the sweep. Only struct irqaction is
usefully greppable, so there may be some assignments to ->mask missing
still. This removes more code than it adds.

[PATCH] cpumask: rewrite cpumask.h - single bitmap based implementation
From: Paul Jackson <pj@sgi.com>
Major rewrite of cpumask to use a single implementation, as a struct-wrapped
bitmap.
This patch leaves some 26 include/asm-*/cpumask*.h header files orphaned - to
be removed next patch.
Some nine cpumask macros for const variants and to coerce and promote between
an unsigned long and a cpumask are obsolete. Simple emulation wrappers are
provided in this patch for these obsolete macros, which can be removed once
each of the 3 archs (i386, ppc64, x86_64) using them are recoded in follow-on
patches to not need them.
The CPU_MASK_ALL macro now avoids leaving possible garbage one bits in any
unused portion of the high word.

[PATCH] cpumask: make cpu_present_map real even on non-smp
From: Paul Jackson <pj@sgi.com>
This patch makes cpu_present_map a real map for all configurations, instead of
a constant for non-SMP. It also moves the definition of cpu_present_map out
of kernel/cpu.c into kernel/sched.c, because cpu.c isn't compiled into non-SMP
kernels.
The pattern is that each of the possible, present and online cpu maps are
actual kernel global cpumask_t variables, for all configurations. They are
documented in include/linux/cpumask.h. Some of the UP (NR_CPUS=1) code
cheats, and hardcodes the assumption that the single bit position of these
maps is always set, as an optimization.

[PATCH] rcu: avoid passing an argument to the callback function
From: Dipankar Sarma <dipankar@in.ibm.com>
This patch changes the call_rcu() API and avoids passing an argument to the
callback function as suggested by Rusty. Instead, it is assumed that the
user has embedded the rcu head into a structure that is useful in the
callback and the rcu_head pointer is passed to the callback. The callback
can use container_of() to get the pointer to its structure and work with
it. Together with the rcu-singly-link patch, it reduces the rcu_head size
by 50%. Considering that we use these in things like struct dentry and
struct dst_entry, this is good savings in space.
An example :
struct my_struct {
struct rcu_head rcu;
int x;
int y;
};
void my_rcu_callback(struct rcu_head *head)
{
struct my_struct *p = container_of(head, struct my_struct, rcu);
free(p);
}
void my_delete(struct my_struct *p)
{
...
call_rcu(&p->rcu, my_rcu_callback);
...
}

[PATCH] rcu lock update: Use a sequence lock for starting batches
From: Manfred Spraul <manfred@colorfullife.com>
Step two for reducing cacheline trashing within rcupdate.c:
rcu_process_callbacks always acquires rcu_ctrlblk.state.mutex and calls
rcu_start_batch, even if the batch is already running or already scheduled to
run.
This can be avoided with a sequence lock: A sequence lock allows to read the
current batch number and next_pending atomically. If next_pending is already
set, then there is no need to acquire the global mutex.
This means that for each grace period, there will be
- one write access to the rcu_ctrlblk.batch cacheline
- lots of read accesses to rcu_ctrlblk.batch (3-10*cpus_online()). Behavior
similar to the jiffies cacheline, shouldn't be a problem.
- cpus_online()+1 write accesses to rcu_ctrlblk.state, all of them starting
with spin_lock(&rcu_ctrlblk.state.mutex).
For large enough cpus_online() this will be a problem, but all except two
of the spin_lock calls only protect the rcu_cpu_mask bitmap, thus a
hierarchical bitmap would allow to split the write accesses to multiple
cachelines.
Tested on an 8-way with reaim. Unfortunately it probably won't help with Jack
Steiner's 'ls' test since in this test only one cpu generates rcu entries.

[PATCH] rcu lock update: Add per-cpu batch counter
From: Manfred Spraul <manfred@colorfullife.com>
Below is the one of my patches from my rcu lock update. Jack Steiner tested
the first one on a 512p and it resolved the rcu cache line trashing. All were
tested on osdl with STP.
Step one for reducing cacheline trashing within rcupdate.c:
The current code uses the rcu_cpu_mask bitmap both for keeping track of the
cpus that haven't gone through a quiescent state and for checking if a cpu
should look for quiescent states. The bitmap is frequently changed and the
check is done by polling - together this causes cache line trashing.
If it's cheaper to access a (mostly) read-only cacheline than a cacheline that
is frequently dirtied, then it's possible to reduce the trashing by splitting
the rcu_cpu_mask bitmap into two cachelines:
The patch adds a generation counter and moves it into a separate cacheline.
This allows to removes all accesses to rcu_cpumask (in the read-write
cacheline) from rcu_pending and at least 50% of the accesses from
rcu_check_quiescent_state. rcu_pending and all but one call per cpu to
rcu_check_quiescent_state access the read-only cacheline. Probably not enough
for 512p, but it's a start, just for 128 byte more memory use, without slowing
down rcu grace periods. Obviously the read-only cacheline is not really
read-only: it's written once per grace period to indicate that a new grace
period is running.
Tests on an 8-way Pentium III with reaim showed some improvement:
oprofile hits:
Reference: http://khack.osdl.org/stp/293075/
Hits %
23741 0.0994 rcu_pending

5475 0.0382 rcu_check_quiescent_state
3604 0.0252 rcu_check_callbacks
The total runtime differs between both runs, thus the % number must
be compared: Around 50% faster. I've uninlined rcu_pending for the
test.
Tested with reaim and kernbench.
Description:
- per-cpu quiescbatch and qs_pending fields introduced: quiescbatch contains
the number of the last quiescent period that the cpu has seen and qs_pending
is set if the cpu has not yet reported the quiescent state for the current
period. With these two fields a cpu can test if it should report a
quiescent state without having to look at the frequently written
rcu_cpu_mask bitmap.
- curbatch split into two fields: rcu_ctrlblk.batch.completed and
rcu_ctrlblk.batch.cur. This makes it possible to figure out if a grace
period is running (completed != cur) without accessing the rcu_cpu_mask
bitmap.
- rcu_ctrlblk.maxbatch removed and replaced with a true/false next_pending
flag: next_pending=1 means that another grace period should be started
immediately after the end of the current period. Previously, this was
achieved by maxbatch: curbatch==maxbatch means don't start, curbatch!=
maxbatch means start. A flag improves the readability: The only possible
values for maxbatch were curbatch and curbatch+1.
- rcu_ctrlblk split into two cachelines for better performance.
- common code from rcu_offline_cpu and rcu_check_quiescent_state merged into
cpu_quiet.
- rcu_offline_cpu: replace spin_lock_irq with spin_lock_bh, there are no
accesses from irq context (and there are accesses to the spinlock with
enabled interrupts from tasklet context).
- rcu_restart_cpu introduced, s390 should call it after changing nohz:
Theoretically the global batch counter could wrap around and end up at
RCU_quiescbatch(cpu). Then the cpu would not look for a quiescent state and
rcu would lock up.

[PATCH] jbd needs to wait for locked buffers
From: Chris Mason <mason@suse.com>
jbd needs to wait for any io to complete on the buffer before changing the
end_io function. Using set_buffer_locked means that it can change the
end_io function while the page is in the middle of writeback, and the
writeback bit on the page will never get cleared.
Since we set the buffer dirty earlier on, if the page was previously dirty,
pdflush or memory pressure might trigger a writepage call, which will race
with jbd's set_buffer_locked.

Following up on Keith's code, I adapted the i386 code to allow enabling

enable status. Obviously there will be a text increase (only for non
CONFIG_SPINLINE case), although it doesn't seem so bad, there will be an
increased exit latency when we attempt a lock acquisition after spinning
due to the extra instructions. How much this will affect performance I'm
not sure yet as I haven't had time to micro bench.

AC97) to control interrupt routing for those. In drivers/pci/quirks.c we
set it correctly (dev->irq & 15). However, in pirq_enable_irq() where the
second half of that stuff lives, we forget to apply the mask.
That's what causes problems with ioapic on via motherboards in 2.6.
One-liner below ACKed by Alan, verified on via-based boxen here, obviously
doesn't affect non-via ones (we only set interrupt_line_quirk for via
chipsets).

[PATCH] Handle altivec assist exception properly
This is the PPC64 counterpart of the PPC32 Altivec assist exception
handler that went in recently.
On PPC64 machines with Altivec (i.e. machines that use the PPC970 chip,
such as the G5 powermac), the altivec floating-point instructions can
operate in two modes: one where denormalized inputs or outputs are
truncated to zero, and one where they aren't. In the latter mode the
processor can take an exception when it encounters denormalized
floating-point inputs or outputs rather than dealing with them in
hardware.
This patch adds code to deal properly with the exception, by emulating
the instruction that caused the exception. Previously the kernel just
switched the altivec unit into the truncate-to-zero mode, which works
but is a bit gross. Fortunately there are only a limited set of altivec
instructions which can generate the assist exception, so we don't have
to emulate the whole altivec instruction set.
Note that Altivec is Motorola's name for the PowerPC vector/SIMD
instructions; IBM calls the same thing VMX, and currently only IBM makes
64-bit PowerPC CPU chips. Nevertheless, I have used the term Altivec in
the PPC64 code for consistency with the PPC32 code.

[PATCH] radeonfb: Fix panel detection on some laptops
The code in radeonfb looking for the BIOS image currently uses the BIOS
ROM if any, and falls back to the RAM image if not found. This is
unfortunatly not correct for a bunch of laptops where the real panel
data are only present in the RAM image.
This works around this problem by preferring the RAM image on mobility
chipsets. This is definitely not the best workaround, we need some arch
support for linking the RAM image to the PCI ID (preferrably by having
the arch snapshot it during boot, isolating us completely from the
details of where this image is in memory). I'll see how we can get such
an improvement later.

[libata sata_sil] Re-fix mod15write bug
Certain early SATA drives have problems with write requests whose
length satisfy the equation "sectors % 15 == 1", on the SiI 3112.
Other drives, and other SiI controllers, are not affected.
The fix for this problem is to avoid such requests, in one of three
ways, for the affect drive+controller combos:
1) Limit all writes to 15 sectors
2) Use block layer features to avoid creating requests whose
length satisfies the above equation.
3) When a request satisfies the above equation, split the request
into two writes, neither of which satisfies the equation.
I chose fix #1, the most simple to implement. After discussion with
Silicon Image and others regarding the impact of this fix, I have
decided to remain with fix #1, and will not be implementing a
"better fix". This means that the affected SATA drives will see
decreased performance, but set of affected drives is small and will
never grow larger.
Further, the complexity of implementing solution #2 or
solution #3 is rather large.
When implementing lba48 'large request' support, I unintentionally
broke the fix for these affected drives. Kudos to Ricky Beam for
noticing this.
This change restores the fix, by adding a flag ATA_DFLAG_LOCK_SECTORS
to indicate that the max_sectors value set by the low-level driver
should never be changed.

[PATCH] kbuild: add deb-pkg target
To prepare kbuild for more kernel packaging formats move all packaging support
to scripts/package.
In top-level Makefile introduce generic support for all package formats using
target names *-pkg. Included the old rpm target for backward compatibility.
A new variable KBUILD_IMAGE is used to specify what kernel image will be part
of the final package, and is to be set by the arch specific makefile.
KBUILD_IMAGE may be overridden from command line or environment. KBUILD_IMAGE
will see wider usage later, mainly when installing kernel images.
Introducing KBUILD_IMAGE allowed arch specific details to be deleted from the
mkspec and builddeb scripts.
While in the process added the deb packet format. Script is From: Wichert
Akkerman <wichert@wiggy.net>
To create a RPM packet use 'make rpm-pkg'.
To create a deb packet use 'make deb-pkg'.
Both targets are included in 'make help'

Firmware is usually provided in separate filer '_shipped', and there is no

[PATCH] fix possible stack corruption during reiserfs_file_write
With preallocation turned on, reiserfs_allocate_blocks_for_region wasn't
sending a large enough array to hold all the blocks it was asking the block
allocator to find. This can result in stack corruption.
The fix is to kmalloc an array to hold the blocks, making sure to allocate
something large enough.
There was also a recent optimization to force the allocator to find a free
region large enough to hold the entire preallocation size. This was
sometimes causing more blocks to be allocated then had been requested,
which would also overflow the array. Something more elegant is required
here, until then just disable the optimization.

[PATCH] v4l: tuner + tda9887 updates
This is a big update for the tuner and tda9887 modules which are used for TV
card tuning.
The tda9887 module is basically completely rewritten and understands all the
config bits now instead of having just some fixed config presets. Some of
these config bits can be changed by insmod options now.
The other big change is that both modules allow to use the V4L2 API for
inter-module communication (i.e. when bttv/saa7134/... pass through the
tuning ioctls to the modules). That allows to specify the TV norm more
precisely (not just PAL but PAL-I, PAL-BG, ...), which is needed in some cases
to make TV audio work correctly. Using the old v4l1 API is still possible so

[PATCH] iommu max segment size
This patch is from James, I've changed it slightly only.
The problem is that some IOMMU implementations have a maximum limit to the
size of the number of contiguously mappable pages (admittedly, this limit
is mostly in the resource management algorithms rather than the IOMMUs
themselves).
This patch adds this concept to the bio layer via the parameter
BIO_VMERGE_MAX_SIZE
which architectures can define in asm/io.h (if undefined, we assume it to
be infinite, which is current behaviour).
While adding this, I noticed several places where bio was making incorrect
assumptions about virtual mergeability (none of which was a bug: bio was
overestimating rather than underestimating).
- The worst offender was bio_add_page(), which seemed never to check for
virtual mergeability
- I also fixed blk_hw_contig_segments() not to check the QUEUE_CLUSTER
flag, and not to check the phys segment boundary.
In order to track the hw segment size across bios, I had to introduce two
extra bio parameters: bi_hw_front_size and bi_hw_back_size which store the
sizes of the front and back hw contiguous segments (and which will be equal
if there's only one hw segment). When the bio is merged into a request,
these fields are updated with the total hw contig size so they can always
be used to assess if the merger would violate the BIO_VMERGE_MAX_SIZE
parameter.

[PATCH] Add ovcamchip driver
This patch adds a new driver for the OmniVision OV6xx0 and OV7xx0 series of
CMOS image sensors. It is currently used by the w9968cf USB webcam driver,
which is already in mainline 2.6. Up until now it had to be compiled
outside the kernel tree, which is clearly suboptimal.
It is also used by version 2 of the ov511 USB webcam driver, which will be
merged in the near future. That will reduce some code duplication, since
the existing ov511 has much of this code built-in.
This was previously submitted to Linux-USB-Devel, and I have fixed the
concerns that came up at that time.

[PATCH] O_NOATIME support
This patch adds support for the O_NOATIME open flag (GNU extension):
int O_NOATIME Macro
If this bit is set, read will not update the access time of the file.
See File Times. This is used by programs that do backups, so that
backing a file up does not count as reading it. Only the owner of the
file or the superuser may use this bit.
It is useful if you want to do something with the file atime (for instance,
moving files that have not been accessed in a while to somewhere else, or
something like Debian's popularity-contest) but you also want to read all
files periodically (for instance, tripwire or debsums).
Currently, the program that reads all files periodically has to use utimes,
which can race with the atime update:
A B
open
fstat
read
open
read
close
close
utimes
And the file still has the old atime, instead of the new one from when B
did the read from it. This problem does not happen if A uses O_NOATIME
instead of utimes to preserve the atime.
This patch adds the O_NOATIME constant for all architectures, but it would
also be possible to add it one architecture at a time by defining it to 0
when not defined in asm-*.

[PATCH] Permit inode & dentry hash tables to be allocated > MAX_ORDER size
Here's a patch to allocate memory for big system hash tables with the
bootmem allocator rather than with main page allocator.
It is needed for three reasons:
(1) So that the size can be bigger than MAX_ORDER. IBM have done some
testing on their big PPC64 systems (64GB of RAM) with linux-2.4 and found
that they get better performance if the sizes of the inode cache hash,
dentry cache hash, buffer head hash and page cache hash are increased
beyond MAX_ORDER (order 11).
Now the main allocator can't allocate anything larger than MAX_ORDER, but
the bootmem allocator can.
In 2.6 it appears that only the inode and dentry hashes remain of those
four, but there are other hash tables that could use this service.
(2) Changing MAX_ORDER appears to have a number of effects beyond just
limiting the maximum size that can be allocated in one go.
(3) Should someone want a hash table in which each bucket isn't a power of
two in size, memory will be wasted as the chunk of memory allocated will
be a power of two in size (to hold a power of two number of buckets).
On the other hand, using the bootmem allocator means the allocation
will only take up sufficient pages to hold it, rather than the next power
of two up.
Admittedly, this point doesn't apply to the dentry and inode hashes,
but it might to another hash table that might want to use this service.
I've coelesced the meat of the inode and dentry allocation routines into
one such routine in mm/page_alloc.c that the the respective initialisation
functions now call before mem_init() is called.
This routine gets it's approximation of memory size by counting up the
ZONE_NORMAL and ZONE_DMA pages (and ZONE_HIGHMEM if requested) in all the
nodes passed to the main allocator by paging_init() (or wherever the arch
does it). It does not use max_low_pfn as that doesn't seem to be available
on all archs, and it doesn't use num_physpages since that includes highmem
pages not available to the kernel for allocating data structures upon -
which may not be appropriate when calculating hash table size.
On the off chance that the size of each hash bucket may not be exactly a
power of two, the routine will only allocate as many pages as is necessary
to ensure that the number of buckets is exactly a power of two, rather than
allocating the smallest power-of-two sized chunk of memory that will hold
the same array of buckets.
The maximum size of any single hash table is given by
MAX_SYS_HASH_TABLE_ORDER, as is now defined in linux/mmzone.h.

This patch creates and exports 2 functions which can be used by the rest of
kernel code to perform DMI data checks:
- dmi_check_system() function checks system DMI data against given blacklist

- dmi_get_system_info() function returns DMI data value. Useful for people
wanting more complex DMI data check than simple string match.
Also filling unused match entries with NO_MATCH made optional, but existing
NO_MATCH occurences are left intact, so people are free to continue dmi_scan.c

[PATCH] FAT: don't use "utf8" charset and NLS_DEFAULT
Recently, some distributors have set "utf8" to NLS_DEFAULT, therefore,
FAT uses the "iocharset=utf8" as default. But, since "iocharset=utf8"
doesn't provide the function (lower <-> upper conversion) which FAT
needs, so FAT can't provide suitable behavior.
This patch does:
- doesn't recognize "utf8" as "iocharset"
- doesn't use NLS_DEFAULT as default "iocharset"
- instead of NLS_DEFAULT, adds FAT_DEFAULT_CODEPAGE and
FAT_DEFAULT_IOCHARSET
NOTE: the following looks like buggy, so it's not recommended
"codepage=437,iocharset=iso8859-1,utf8"
however, some utf8 file name can handle. (in this case, it uses the
table of iso8859-1 for lower <-> upper conversion)

[PATCH] fix amd64 boot breakage
This fixes a bug that prevent my amd64 box from booting;
numa_default_policy was __init however it's called like this in
init/main.c:
free_initmem();
unlock_kernel();
system_state = SYSTEM_RUNNING;
numa_default_policy();
eg after free_initmem(). This resulted in it being reused/freed and that
gives a nasty oops.

[PATCH] pcnet32: recover after rx hang.
This patch fixes a receive hang that occasionally occurs after a Tx
FIFO underrun. The receive dma remains in a hung state sometimes. The
transmit operations continue to occur, but no receive activity.
This was reproduced on several ppc64 systems and the fix has been verified
there. The patch has been tested as well on an ia32 system, which did
not experience the hang because it did not have fifo underruns, which is
a preqrequisite for the hang. The memory barriers decreased the frequency
of occurrence. The final change to reset the chip instead of just stopping
it eliminated the last hangs.
Please also apply against 2.4.7 (with offset of -1), tested ia32.

[PATCH] sparse: drivers/message/fusion annotations and fixes
Sigh... First of all, LSI folks have very quaint idea of existing
platforms and word sizes on those. Their definitions of U32 and S32
should really be reserved for posterity (preferably chiseled into the
rock they have between the ears), but kernel is the wrong place for
that. Fixed.
mptctl_do_mpt_command() was always called on userland pointers;
kernel/userland argument removed along with dead code, function
annotated, callers updated.
The rest is trivial annotations in mptctl.c and in its ioctl structures
- nothing fancy there.

[BRIDGE]: Kill sysfs hotplug avoidance hacks.
The whole effort to avoid hotplug was misguided. If it is really a problem
(which it doesn't appear to be) then it can more easily be addressed by smarter
hotplug scripts in user space.
This patch gets rid of the whole subsystem hack for bridge kobjects.

Patch from Nicolas Pitre
Let's make it coherent with what the actual code is doing and has

just fix the comment. The most natural usage pattern for this is
a base address and a size so it's more efficient to have an exclusive

[PATCH] USB: dummy_hcd shouldn't reject SET-ADDRESS requests
This patch for the dummy_hcd driver prevents it from rejecting SET-ADDRESS
requests when the address is already set. The USB 2.0 spec states that if
a device is in the ADDRESS state, it should accept and start using the new
address. Behavior in the CONFIGURED state is undefined, but since
dummy_hcd doesn't keep track of the difference between the two states we
might as well accept the new address in any case.

[PATCH] cfq direct io alias problem
This is a fix for when we encounter an alias during insert. When that
happens we move the request to dispatch, but it may happen that this
request is also the ->last_merge hint. So we may attempt to merge with
this later, when it's either in progress or already freed. Rearrange the
logic a bit so we clear the merge hint there as well. It looks more
complex than it is, the only real code change is the addition of a
cfq_remove_merge_hints() in cfq_dispatch_sort().

[PATCH] RLIM: enforce rlimits on queued signals
Add a user_struct pointer to the sigqueue structure. Charge sigqueue
allocation and destruction to the user_struct rather than a global pool. This
per user rlimit accounting obsoletes the global queued_signals accouting.
The patch as charges the sigqueue struct allocation to the queue that it's
pending on (the receiver of the signal). So the owner of the queue is charged
for whoever writes to it (much like quota for a 777 file).
The patch started out charging the task which allocated the sigqueue struct.
In most cases, these are always the same user (permission for sending a
signal), so those cases are moot. In the cases where it isn't the same user,
it's a privileged user sending a signal to another user.
It seems wrong to charge the allocation to the privleged user, when the other
user could block receipt as long as it feels. The flipside is, someone else
can fill your queue (expectation is that someone else is privileged). I think
it's right the way it is. The change to revert is very small.

It turns out there is a bug in hugetlb_prefault(): with 3 level page table,
huge_pte_alloc() might return a pmd that points to a PTE page. It happens
if the virtual address for hugetlb mmap is recycled from previously used
normal page mmap. free_pgtables() might not scrub the pmd entry on munmap
and hugetlb_prefault skips on any pmd presence regardless what type it is.

[PATCH] IPMI base patch to fix channel handling and add polling
This patch fixes some problems with handling of channel detection in the

This patch also adds a polling interface; this is required for situations
where interrupts are not running, but the system must still issue IPMI
commands, like when taking a crash dump.

[PATCH] Updates to rivafb driver
The patch updates rivafb to the following:
1. Fixed cursor corruption and simplified cursor code.
2. Maximized var->yres_virtual on initial mode setting. Scrolling,
therefore, defaults to y-panning which is significantly faster.
3. Restricted var->xres_virtual and var->yres_virtual to 0x7fff
(hardware limitation?). Otherwise, var->yres_virtual > 0x7fff + panning
will hang the GPU.
4. Added I2C/DDC support. This feature enables independent mode setup
to rivafb. 'stty rows n cols n' should now work correctly. This is a
configurable option.
5. Various/minor fixes to drawing code.

date. The arch_set_page_uptodate function of s390 may not clear the dirty
bit in that case otherwise a dirty bit which is set between the start of an
i/o for a writeback and a following call to SetPageUptodate is lost.

[PATCH] add 1 in __const_udelay()
The "mull" instruction in __const_udelay() cuts off the lower 32 bits --
so, it is "rounding down". This is both an issue for small ndelay()s for
_all_ values for loops_per_jiffy and for certain {n,u}delay()s for many
loops_per_jiffy values.
Assuming
LPJ = 1501115
udelay(87)
results in
130597 loops to be spent.
However, 1000 * 130597 / 1501115 is 86.999997 us, so we're actually
_rounding down_. 1000 * 130598 / 1501115 is 87.000662841, which would be
the technically correct thing to do. Of course, for the TSC case this
won't matter as the maths take some time, so the actual delay is
1000 * __udelay(x) / lpj + __OVERHEAD(x)
Anybody worried about both the additional overhead and the fact that the
overhead takes some time to run should add a check
if (unlikely(xloops < OVERHEAD))
return;
xloops -= OVERHEAD;
to the delay() routines in arch/i386/kernel/timers/*.c and determine
what the OVERHEAD is.

[PATCH] round up in __udelay()
Round up in __udelay(): 2**32 / 100000 is 4294.97, so it's more intuitive
to round up, and it causes more predictable results:
n usec delay on a 1500000 BogoMIPS system:
n before -mull after
1 1000 ticks 1499 ticks 1500 ticks
10 14000 ticks 14999 ticks 15000 ticks
n usec delay on a 100000 BogoMIPS system:
n before -mull after
1 0 ticks 99 ticks 100 ticks
10 0 ticks 999 ticks 1000 ticks
100 9000 ticks 9999 ticks 10000 ticks
While it can be argued that some time is also spent in the delay functions,
it's better to spend _at least_ the specified time sleeping, in my humble
opinion. And the overhead of a specific ->delay() implementation should be
substracted in the specific ->delay() implementation.

[PATCH] mull'ify multiplication with HZ in __const_udelay()
John Stultz mentioned on lkml ( http://lkml.org/lkml/2004/6/5/15 ) that
calls to udelay() don't delay long enough, causing trouble e.g. in the USB
subsystem. The following patches address this issue.
Move the multiplication of (loops_per_jiffy * xloops) with HZ into the
"mull" asm operation. This increases the accuracy of the delay functions
largely:
n usec delay on a system with loops_per_jiffy = 1500000 :
n before after
1 1000 ticks 1499 ticks
10 14000 ticks 14999 ticks
n usec delay on a system with loops_per_jiffy = 100000 :
n before after
1 0 ticks 99 ticks
10 0 ticks 999 ticks
100 9000 ticks 9999 ticks
As noted by Kurt Garloff, it's necessary to adjust for large
loops_per_jiffies, as the multiplication of it with HZ fails for 4GHz or
larger. So, John Stultz suggested multiplying xloops with 4 first, and
multiplying with (HZ/4).

that in certain catalogue entries, the extension separator character '/'

thus Linux cannot properly parse this without this patch, thinking that it

Subject: pb in handling parameters on kernel command line
To: submit@bugs.debian.org (debian bug tracking system)
Hello, I found some bugs in kernel command line parser. AFAIK, they are not
Debian nor sparc specific but I'm not subscribed to linux-kernel mailing list
and since I'm involved with boot-floppies (mainly for sparc), I think I'm right
to report it here. Feel free to forward it upstream (I checked the latest
2.3.46 sources and it seems these bugs are still there).
These bugs are not release critical. The latter just not gives the user a
chance to overwrite TERM env var at boot time. It could be just
inconvenient for serial console boot, and in this case, our busybox' init is
already enforcing TERM=vt102.
Nevertheless if it could not be fixed before the release, I could even write a
workaround in busybox' init (it's just a matter of rewriting getenv()).
At last, it does not affect sysvinit package because serial console tty is
controlled by a getty process which is reading terminal settings on its command
line (take a look in inittab for T0 entries, if any).
Ok, here is my modest contribution to kernel hacking. I don't know much about
kernel internals but it seems that argument parsing is a bit broken.
One trivial patch for command line like "init=/bin/sh console=prom" where
console=prom is replaced by lot of spaces in previous call to setup_arch() on
sparc, therefore the line parsed by parse_options() is really
"init=/bin/sh " and a lot of null args are pushed into argv_init.
The other patch is for command line like "TERM=vt100" where both default & user
TERM entries are pushed into the env array.
Taking a look into /proc/1/environ, it shows up:
HOME=/
TERM=linux
TERM=vt100
It appears that ash (maybe other shells too) is giving the latter entry but
glibc getenv() is giving the former. It is therefore impossible to get entry
from the user in a C program like busybox' init (used in Debian boot-floppies).
I guess getenv() is not written to support duplicate entries, therefore the
kernel should avoid such construct.

[PATCH] Shift+PgUp if nr of scrolled lines is < 4
Using the vga console driver, if the number of the lines scrolled out is
less than four, then Shift+PageUp doesn't work.
The bug is closely related to the 'margin' feature of scrolling, which
means that if less than four lines should remain unvisible in the direction
we are scrolling to, then we scroll a little bit more just to see those few
lines. Kind of two small magnets at the borders of the buffer.
This bug was also reported with maybe a less clear description by Stepan
Koltsov (cc'ed just for fun) back in 2001 and he got no answer. I found it
at http://seclists.org/lists/linux-kernel/2001/Nov/0080.html
His patch simply disables margin support and hence everythings becomes
okay, but you lose a nice feature.
Here's a patch that retains margin support and fixes the bug. Works for
me, tested for a week. No guarantee. As I don't fully understand the code
(see also my previous mail) I'm not 100% sure that I'm doing the right
thing, so I'd prefer if someone would take a closer look at it.
At least 2.4 and 2.6 are affected, maybe older ones too.

[PATCH] epoll: replace the file lookup hash with rbtrees
The epoll allocation for the fd lookup hash used to allocate up to 1MB
(depending on the "hint" size passed to epoll_create()) with
__get_free_pages(0), and this might lead to a "malicious" user to do
something like:
for (i = 0; i < 1024; i++)
epoll_create(BIG-NUM);
You can replace "malicious user" with IBM-ltp test suite, and the meaning
does not change. The above code might exhaust memory badly, even before
the file creation limit is topped. Also, the allocation was independent
from the number of fds pushed into the epoll fd hash. Using an rb-tree
ther will be not pre-allocation of the hash, and the size of the memory
used will be proportional to the number of fds pushed into the epoll fd.
The patch also removes 100 lines of code, that is never a bad thing ;)

[PATCH] checksatck.pl fixes
- "\<" and "\>" can be safely replaced with "<" and ">"
- "$var =~ /^string$/" is better written "$var eq 'string'"
- $i is better written without the double quotes
- it's not safe to use for without "my"ing the iteration variable
- "print foreach @array" is better written "print @array"
- declare variables
- ".*" is useless at the end of a regexp
- "$a[@a] = $foo" is a rather obfuscated syntax for "push @a, $foo"...

[PATCH] Use numa policy API for boot time policy
Suggested by Manfred Spraul.
__get_free_pages had a hack to do node interleaving allocation at boot
time. This patch sets an interleave process policy using the NUMA API for
init and the idle threads instead. Before entering the user space init the
policy is reset to default again. Result is the same.
Advantage is less code and removing of a check from a fast path.
Removes more code than it adds.
I verified that the memory distribution after boot is roughly the same.

Marking invalid APIC ID's in phys_cpu_present_map was intended to generate

properly bounds-check everywhere. So this patch removes that marking of

[PATCH] APIC enumeration fixes
The following patch appears sound according to an audit to ensure that all
of the codepaths where it was introduced were called after the APIC
fixmappings were set up.
This patch introduces get_physical_broadcast(), which checks the version ID
of the local APIC to determine whether it's a serial APIC or xAPIC, and
returns the correct physical broadcast ID. It replaces all uses of
APIC_BROADCAST_ID and IO_APIC_MAX_ID with this in order to ensure. It also
changes the checks during MP table parsing so the APIC ID is checked in
tandem with the version number.
I'm holding out for some kind of testing to get an idea of whether this
covers the cases or introduces regressions, or whatever.

[PATCH] 3c59x: support for ATI Radeon 9100 IGP
The following patch adds support for the 3Com networking core found in the
ATI Radeon 9100 IGP southbridge used on boards like Asus P4R800-VM.
The main point of this patch is using HAS_MII instead of HAS_NWAY for the
definition of the board. All the previous trials since the end of last
year used HAS_NWAY which disables the Tx part of the transceiver; using
HAS_NWAY was the way all 3Com Cyclone and Tornado chips worked, as they had
the transceiver integrated. The ATI solution has an external transceiver
and I had to physically see the different chip on the board (the board was
provided by ATI) to finally understand that it needs the HAS_MII
definition... I'm still waiting for some docs from ATI to clarify if this
is the correct way of handling this chip and if there are any differences
w.r.t EEPROM handling, but as it appears to work and was also confirmed by
other testers, I don't want to keep owners of such boards away from their
networks :-)
The textual identification was a bit hard to decide; it's called
"3c920B-EMB-WNM" in the Windows .INF file that Asus provides for their
boards. As this name was already used for PCI ID 9210, I added the
paranthesis which specifies where this chip is found.
The Scyld driver defines FEATURE_TORNADO to include HAS_NWAY. This board
would then probably need to not be defined with FEATURE_TORNADO, but the
same as in this patch.
I would like to publicly thank Tyson Vickers for both ideas and patience
during the last few weeks. He managed to get the driver working by
randomly setting driver parameters :-) But then he contacted me and worked
with me towards the solution.

[PATCH] sisfb update 1.7.10
attached is an update for the sisfb driver to version 1.7.10.
This update includes
- fixes for pure 64bit and 32/64bit mixed systems (add ioctl conversion;
fix variable sizes, etc; REQUIRED for current X.org/XFree86 on 64bit
systems, even if pure 64bit),
- fixes for 301C video bridge, (scales TV output correctly now)
- fixes for 1600x1200 and 1400x1050 LCD panels,
- many fixes for 661/741/760 (amongst others, proper LFB support for the
760 and corrections for SiS' new BIOS data layout; would lead to display
corruption with old driver)
- add support for many modes for LCD which were unsupported previously,
- add support for HiVision and YPbPr HDTV
- "vga=" statement now honoured properly (sisfb will set the same mode as
the kernel did by default)
- use LCD native resolution mode if no mode is given
- a major clean up of main driver code,
- radical removal of duplicate (or nearly duplicate) code,
- switched to 2.6 module_param macros,
- enhanced communication with the X driver,
- added eventual POSTing of SiS300/305 card for non-x86 archs,
- added ability to relocate the image on the TV screen using a userland
tool,
- added Documentation/fb/sisfb.txt (why the heck was this missing?!)
- small fix for SiS DRM driver (match 32/64bit fixes mentioned above)
(cast the data passed to sis_free as u32)
- make driver re-entrant by avoiding static structures and variables.
As usual, heavily tested. The mode switching code is even lab-tested by
SiS (although 100% written by me). Please apply asap (especially since
64bit systems were not properly supported previously; as mentioned, current
X.org/XFree86 needs this update for proper communication with the
framebuffer driver on 64bit systems. X crashes on such systems with the
old driver).

[PATCH] iso9660: fix handling of inodes beyond 4GB
This is my fourth attempt to patch the isofs code. It is similar to the last
posting except this one implements the NFS get_parent() method which has
always been missing.
The original problem I set out to addresses is that the current iso9660 file
system cannot reach inodes located beyond the 4GB barrier. This is caused by
using the inode number as the byte offset of the inode data. Being 32-bits
wide, the inode number is unable to reach inode data that does not reside on
the first 4GB of the file system.
This causes real problems with "growisofs"
http://fy.chalmers.se/~appro/linux/DVD+RW/#isofs4gb
and my pet project "shunt"
http://www.serice.net/shunt/
This patch switches the isofs code from iget() to iget5_locked() which allows
extra data to be passed into isofs_read_inode() so that inode data anywhere on
the disk can be reached.
The inode number scheme was also changed. Continuing to use the byte offset
would have resulted in non-unique inodes in many common situations, but
because the inode number no longer plays any role in reading the meta-data off
the disk, I was free to set the inode number to some unique characteristic of
the file. I have chosen to use the block offset which is also 32-bits wide.
Lastly, the pre-patch code uses the default export_operations to handle
accessing the file system through NFS. The problem with this is that the
default NFS operations assume that iget() works which is no longer the case
because of the necessity of switching to iget5_locked(). So, I had to
implement the NFS operations too. As a bonus, I went ahead and implemented
the NFS get_parent() method which has always been missing.

[PATCH] BSD accounting format rework
BSD accounting format rework:
Use all explicit and implicit padding in struct acct to
- correctly report 32 bit uid/gid,
- correctly report jobs (e.g., daemons) running longer than 497 days,
- increase the precision of ac_etime from 2^-13 to 2^-20
(i.e., from ~6 hours to ~1 min. after a year)
- store the current AHZ value.
- allow cross-platform processing of the accounting file
(limited for m68k which has a different size struct acct).
- introduce versioning for smooth transition to incompatible formats in
the future. Currently the following version numbers are defined:
0: old format (until 2.6.7) with 16 bit uid/gid
1: extended variant (binary compatible to v0 on M68K)
2: extended variant (binary compatible to v0 on everything except M68K)
3: a new binary incompatible format (64 bytes)
4: new binary incompatible format (128 bytes).
layout of its first 64 bytes is the same as for v3.
5: marks second half of new binary incompatible format (128 bytes)
(layout is not yet defined)
All this is accomplished without breaking binary compatibility. 32 bit
uid/gid support is compatible with the patch previously floating around and
used e.g. by Red Hat.
This patch also introduces a config option for a new, binary incompatible
"version 3" format that
- is uniform across and properly aligned on all platforms
- stores pid and ppid
- uses AHZ==100 on all platforms (allows to report longer times)
Much of the compatibility glue goes away when v1/v2 support is removed from
the kernel. Such a patch is at
http://www.physik3.uni-rostock.de/tim/kernel/2.7/acct-cleanup-04.patch
and might be applied in the 2.7 timeframe.
The new v3 format is source compatible with current GNU acct tools (6.3.5).
However, current GNU acct tools can be compiled for only one format. As there
is no way to pass the kernel configuration to userspace, with my patch it will
still only support the old v2 format. Only if v1/v2 support is removed from
the kernel, recompiling GNU acct tools will yield v3 support.
A preliminary take at the corresponding work on cross-platform userspace tools
(GNU acct package) is at
http://www.physik3.uni-rostock.de/tim/kernel/utils/acct/
This version of the package is able to read any of the v0/v2/v3 formats,
regardless of byte-order (untested), even within the same file.
Cross-platform compatibility with m68k (v1 format) is not yet implemented, but
native use on m68k should work (untested). pid and ppid are currently only
shown by the dump-acct utility.

[PATCH] Validate PM-Timer rate at boot time
Add a check to the PM-Timer initialization code. It validates the PM-Timer
rate against PIT channel 2 and rejects the PM-Timer if its rate is not
withing 5% of the expected number.
Rationale:
The PMTMR timers of certain (older) mainboards are running at invalid
rates, often much faster than the rate expected by the PM-Timer code. This
causes the system clock to run much too fast. See also
http://bugme.osdl.org/show_bug.cgi?id=2375
Possible workarounds are disabling the PM-Timer in the kernel config or
disabling the PM-Timer at boot time through the "clock=tsc" parameter.
However, we believe it is more user friendly to automatically validate the
PM-Timer rate at boot time before using it as the system time source.
Tested by me (with broken timer) and John Stultz (with good timer) and
believed to be ok.

[PATCH] ahc1542 !CONFIG_MCA build fix
The old 1542 scsi driver is both ISA and MCA. The MCA portions are disabled
when !CONFIG_MCA through the typical wrapper scheme (a la pci.h and
!CONFIG_PCI). However... the driver unconditionally includes linux/mca.h
which in turn unconditionally includes asm/mca.h.
This breaks drivers on platforms with ISA but not MCA, like alpha.

[PATCH] x86: remove io_apic_sync
The patch below gets rid of io_apic_sync().
io_apic_sync() was introduced in 2.1.104 and it was originally done for
masking and unmasking as well. Later the unmasking use got removed but the
masking use lingered around. I dont think it was ever justified to do it
and clearly since the lack of io_apic_sync() didnt break some of the other
writes we do to the IO-APIC registers, it must be unnecessary in the
masking case too.

If a second thread runs truncate and shrinks i_size, so isize1 and isize2 are
different, the read can return up to a page of zero-fill that shouldn't really
exist.
The trick is to read isize1 after doing the readpage. I realised this is the

setup_arch() overriding any default anyways.
3. s/vram_resource/video_ram_resource/. Lines up much nicer with

[PATCH] Ext3: Retry allocation after transaction commit (v2)
Here is a reworked version of my patch to ext3 to retry certain filesystem
operations after an ENOSPC error. The ext3_should_retry_alloc() function will
not wait on the currently running transaction if there is a currently active
handle; hence this should avoid deadlocks in the Lustre use case. The patch
is versus BK-recent.
I've also included a simple, reliable test case which demonstrates the problem
this patch is intended to fix. (Note that BK-recent is not sufficient to
address this test case, and waiting on the commiting transaction in
ext3_new_block is also not sufficient. Been there, tried that, didn't work.
We need to do the full-bore retry from the top level. The
ext3_should_retry_alloc() will only wait on the committing transaction if
there is an active handle; hence Lustre will probably also need to use
ext3_should_retry_alloc() if it wants to reliably avoid this particular
problem.)

[PATCH] IDR fixups
There were definately some problems in there. I've made some changes and
tested with a lot of bounds. I don't have a machine with enough memory to
fill it up (it would take ~16GB on a 64-bit machine), but I use the "above"
code to simulate a lot of situations.
The problems were:
* IDR_FULL was not the right value
* idr_get_new_above() was not defined in the headers or documented.
* idr_alloc() bug-ed if there was a race and not enough memory was
allocated. It should have returned NULL.
* id will overflow when you go past the end.
* There was a "(id >= (1 << (layers*IDR_BITS)))" comparison, but at
the top layer it would overflow the id and be zero.
* The allocation should return ENOSPC for an "above" value with
nothing above it, but it returned EAGAIN.
I have not tested on 64-bits (as I don't have a 64-bit machine).
I've included the files, a diff from the previous version, and my test
programs.
For the test programs, idr_test <size> will just attempt to allocate
<size> elements, check them, free them, and check them again.
idr_test2 <size> <incr> will allocate <size> element with <incr> between
them.
idr_test3 just tests some bounds and tries all values with just a few in
the idr.

[PATCH] idr: remove counter bits from id's
idr_get_new() currently returns an incrementing counter in the top 8 bits of
the counter. Which means that most users have to mask it off again, and we
only have a 24-bit range.
So remove that counter. Also:
- Remove the BITS_PER_INT define due to namespace collision risk.
- Make MAX_ID_SHIFT 31, so counters have a 0 to 2G-1 range.
- Why is MAX_ID_SHIFT using sizeof(int) and not sizeof(long)? If it's for
consistency across 32- and 64-bit machines, why not just make it "31"?
- Does this still hold true with the counter removed?
/* We can only use half the bits in the top level because there are
only four possible bits in the top level (5 bits * 4 levels = 25
bits, but you only use 24 bits in the id). */
If not, what needs to change?

[PATCH] Fixes for idr code
* On a 32-bit architecture, the idr code will cease to work if you add
more than 2^20 entries. You will not be able to find many of the
entries. The problem is that the IDR code uses 5-bit chunks of the
number and the lower portion used by IDR is 24 bits, so you have one bit
that leaks over into the comparisons that should not be there. The
solution is to mask off that bit before doing IDR processing. This
actually causes the POSIX timer code to crash if you create that many
timers. I have included an idr_test.tar.gz file that demonstrates this
with and without the fix, in case you need more evidence :).
* When the IDR fills up, it returns -1. However, there was no way to
check for this condition. This patch adds the ability to check for the
idr being full and fixes all the users. It also fixes a problem in
fs/super.c where the idr code wasn't checking for -1.
* There was a race condition creating POSIX timers. The timer was added
to a task struct for another process then the data for the timer was
filled out. The other task could use/destroy time timer as soon as it is
in the task's queue and the lock is released. This moves settup up the
timer data to before the timer is enqueued or (for some data) into the
lock.
* Change things so that the caller doesn't need to run idr_full() to find
out the reason for an idr_get_new() failure.
Just return -ENOSPC if the tree was full, or -EAGAIN if the caller needs
to re-run idr_pre_get() and try again.

[PATCH] reiserfs: block allocator optimizations

From: <jeffm@suse.com>
The current reiserfs allocator pretty much allocates things sequentially
from the start of the disk, it works very nicely for desktop loads but
once you've got more then one proc doing io data files can fragment badly.
One obvious solution is something like ext2's bitmap groups, which puts
file data into different areas of the disk based on which subdirectory
they are in. The problem with bitmap groups is that if you've got a
group of subdirectories their contents will be spread out all over the
disk, leading to lots of seeks during a sequential read.
This allocator patch uses the packing locality to determine which bitmap
group to allocate from, but when you create a file it looks in the bitmaps
to see how 'full' that packing locality already is. If it hasn't been
heavily used yet, the packing locality is inherited from the parent
directory putting files in new subdirs close to the parent subdir,
otherwise it is the inode number of the parent directory putting new
files far away from the parent subdir.
The end result is fewer bitmap groups for the same working set. For
example, one test data set created by 20 procs running in parallel has
6822 subdirs. And with vanilla reiserfs that would mean 6822
packing localities. This patch turns that into 26 packing localities.
This makes sequential reads of big directory trees more efficient, but
it also makes the btree more efficient in general. Things end up sorted
better because groups of subdirs end up with similar keys in the btree,
instead of being spread out all over.
The bitmap grouping code tries to use the start of each bitmap group
for metadata, and offsets the data slightly. The data and metadata
are still close together, but not completely intermixed like they are
in the default allocator. The end result is that leaf nodes tend to be
close to each other, making metadata readahead more effective.
The old block allocator had the ability to enforce a minimum
allocation size, but did not use it. It now tries to do a pass looking
for larger allocation chunks before falling back to the old behaviour
of taking any blocks it can find.
The patch changes the defaults to:
mount -o alloc=skip_busy:dirid_groups:packing_groups
You can get back the old behaviour with mount -o alloc=skip_busy
mount -o alloc=dirid_groups will turn on the bitmap groups
mount -o alloc=packing_groups turns on the packing locality reduction code
mount -o alloc=skip_busy:dirid_groups turns on both dirid_groups and
skip_busy
Finally the patch adds a mount -o alloc=oid_groups, which puts files into
bitmap groups based on a hash of their objectid. This would be used for
databases or other situations where you have a limited number of very
large files.
This command will tell you how many packing localities are actually in
use:
debugreiserfs -d /dev/xxx | grep '^|.*SD' | sed 's/^.....//' | awk '{print $1}' | sort -u | wc -l

[PATCH] binfmt_misc: improve calculation of interpreter's credentials
This patch allows for misc binaries to run with credentials and security
token that are calculated according to the binaries, and not according to the
interpreter, which is the legacy behavior of binfmt_misc.
The way it is done is by calling prepare_binprm, which is where these
attributes are calculated, before switching the 'file' field in the bprm from
the binary to the interpreter.
This feature should be used with care, since the interpreter will have root
permissions when running a setuid binary owned by root.
Please note -
- Only root can register an interpreter with binfmt_misc. The feature is
documented and the administrator is advised to handle it with care
- The new feature is enabled only with a special flag in the registration
string. When this flag is not specified the current behavior of
binfmt_misc is kept
- This is the only 'right' way for an interpreter to know the correct
AT_SECURE value for the interpreted binary
From: Chris Wright <chrisw@osdl.org>
This patchset looks OK, except for one problem. It installs the fd (which
could've been unreadable) without unsharing the ->files. So someone can use
this to read unreadable yet executable files. Here's a patch which fixes
that up. I added one bit that's commented out because I'm not positive if a
final steal_locks() is needed.
I did a fair amount of rearranging to simplify the error conditions
relative to the fd_install(), and unshare_files().
From: Chris Wright <chrisw@osdl.org>
I found that the intel patchset (and mine as well) leaked i_writecount on
the original executed file. In addition, I verified that the steal_locks()
bit is indeed needed.

[PATCH] Handle non-readable binfmt_misc executables
<background>
I work in a group that works on enabling the IA-32 Execution Layer
(http://www.intel.com/pressroom/archive/releases/20040113comp.htm) on Linux.
In a few words - this is a dynamic translator for IA-32 binaries on IPF
platform. Following David Mosberger's advice - we use the binfmt_misc
mechanism for the invocation of the translator whenever the user tries to
exec an IA-32 binary.
The EL is meant to help in the migration path from IA-32 to IPF. From our
beta customers we learnt that at first stage - they tend to keep their
environment mostly intact, using the legacy IA-32 binaries.
Such an environment has, naturally, setuid and non-readable binaries. It
will be useless to ask the administrator to change the settings of such an
environment - some of them are very complex, and the administrators are
reluctant to make any changes in a system that already proved itself to be
robust and secure. So, our target with these patches is not to enhance the
support for scripts but rather to allow a translator to be integrated into a
working environment that is not (and should not be) aware to the fact it's
being emulated.
As I said before - it is practically hopeless to expect an administrator of
such a system to change it so that it will suit the current behavior of
binfmt_misc. But, even if we could do that,
I'm not sure it would be a good idea - these changes are likely to be less
secure than the suggested patches -
- In order to execute non-readable binaries the binary will have to be made
readable, which is obviously less secure than allowing only a trusted
translator to read it
- There will be no way for the translator to calculate the accurate
AT_SECURE value for the translated process. This might end up with the
translated process running in a non-secured mode when it actually needs to
be secured.
</background>
I prepared a patch that solves a couple of problems that interpreters have
when invoked via binfmt_misc. currently -
1) such interpreters cannot open non-readable binaries
2) the processes will have their credentials and security attributes
calculated according to interpreter permissions and not those of the
original binary
the proposed patch solves these problems by -
1) opening the binary on behalf of the interpreter and passing its fd
instead of the path as argv[1] to the interpreter
2) calling prepare_binprm with the file struct of the binary and not the
one of the interpreter
The new functionality is enabled by adding a special flag to the registration
string. If this flag is not added then old behavior is not changed.
A preliminary version of this patch was sent to the list on 9/1/2003 with the
title "[PATCH]: non-readable binaries - binfmt_misc 2.6.0-test4". This new
version fixes the concerns that were raised by the patch, except of calling
unshare_files() before allocating a new fd. this is because this feature did
not enter 2.6 yet.
Arun Sharma <arun.sharma@intel.com> says:
We were going through an internal review of this patch:
http://marc.theaimsgroup.com/?l=linux-kernel&m=107424598901720&w=2
which is in your tree already. I'm not sure if this line of code got
sufficient review.
+ /* call prepare_binprm before switching to interpreter's file
+ * so that all security calculation will be done according to
+ * binary and not interpreter */
+ retval = prepare_binprm(bprm);
The case that concerns me is: unprivileged interpreter and a privileged
binary. One can use binfmt_misc to execute untrusted code (interpreter) with
elevated privileges. One could argue that all binfmt_misc interpreters are
trusted, because only root can register them. But that's a change from the
traditional behavior of binfmt_misc (and binfmt_script).
(Update):
Arun pointed out that calculating the process credentials according to the
binary that needs to be translated is a bit risky, since it requires the
administrator to pay extra attention not to register an interpreter which is
not intended to run with root credentials.
After discussing this issue with him, I would like to propose a modified
patch: The old patch did 2 things - 1) open the binary for reading and 2)
calculate the credentials according to the binary.
I removed the riskier part of changing the credentials calculation, so the
revised patch only opens the binary for reading. It also includes few words
of warning in the description of the 'open-binary' feature in
binfmt_misc.txt, and makes the function entry_status print the flags in use.
As for the 'credentials' part of the patch, I will prepare a separate patch
for it and send it again to the LKML, describe the problem and ask for people
comments.

[PATCH] mm: flush TLB when clearing young
Traditionally we've not flushed TLB after clearing the young/referenced bit,
it has seemed just a waste of time. Russell King points out that on some
architectures, with the move from 2.4 mm sweeping to 2.6 rmap, this may be a
serious omission: very frequently referenced pages never re-marked young, and
the worst choices made for unmapping.
So, replace ptep_test_and_clear_young by ptep_clear_flush_young throughout
rmap.c. Originally I'd imagined making some kind of TLB gather optimization,
but don't see what now: whether worth it rather depends on how common
cross-cpu flushes are, and whether global or not.
ppc and ppc64 have already found this issue, and worked around it by arranging
TLB flush from their ptep_test_and_clear_young: with the aid of pgtable rmap
pointers. I'm hoping ptep_clear_flush_young will allow ppc and ppc64 to
remove that special code, but won't change them myself.
It's worth noting that it is Andrea's anon_vma rmap which makes the vma
available for ptep_clear_flush_young in page_referenced_one: anonmm and
pte_chains would both need an additional find_vma for that.

[PATCH] ppc64: Optimize exception/syscall entry/exit
This rewrites the PPC64 exception entry/exit routines to make them
smaller and faster.
In particular we no longer save all of the registers for the common
exceptions - system calls, hardware interrupts and decrementer (timer)
interrupts - only the volatile registers. The other registers are saved
and restored (if used) by the C functions we call. This involved
changing the registers we use in early exception processing from r20-r23
to r9-r12, which ended up changing quite a lot of code in head.S.
Overall this gives us about a 20% reduction in null syscall time.
Some system calls need all the registers (e.g. fork/clone/vfork and
[rt_]sigsuspend). For these the syscall dispatch code calls a stub that
saves the nonvolatile registers before calling the real handler.
This also implements the force_successful_syscall_return() thing for
ppc64.

[PATCH] ia64: switching between CPEI & CPEP
A couple of months ago Hidetoshi Seto from Fujitsu proposed
a patch to provide similar switching between interrupt mode
and polling mode for corrected platform events (CPE) as we
have for processor events (CMC) [with the obvious difference
that not all platforms support an interrupt for CPE].
I dusted it off and made a couple of very minor cleanups (which
Seto-san checked out last night on his test setup and confirmed
still passes).

[PATCH] USB: Only process ports with change events pending
This patch adds a bit-array to the hub driver's private data structure,
used for storing the contents of the hub's interrupt status message. That
message indicates which ports have events pending (and whether the hub
itself has events pending). By only polling the status of the ports
listed in the bit-array we can save a fair amount of overhead in hub
communication.
(The #error test added to hub.h is a little awkward, but it's purely
precautionary -- it won't matter until someone decides to support hubs
with more than 31 ports!)
Also included in the patch, since this seemed the perfect opportunity for
it, is Byron's suggestion for handling hub events in the order in which
they were received.

that the COM1 IRQ is edge triggered, active high, but acpi_register_gsi()

[NET]: Clear dev refs in dst->child.
This is a resend of an earlier patch to dst_dev_event. I've changed
it slightly by moving the input/output assignment into dst_ifdown.
To recap, this patch drops lingering IPsec references to a device that
is being unregistered. The child processing in the GC is too late
since it never runs until the reference on the dst hits zero which
could take a long time for things like TCP connections.
The reason I've left the input/output assignment outside the loop is
because they aren't really necessary for the IPsec dst's, and if
it were in the loop then we'll have to do the same child processing
in ___dst_free as well.
I've tested this with an ESP/IPCOMP tunnel and I can confirm that it
does fix the problem.
