[PATCH] device driver for the SGI system clock, mmtimer
SGI has been using this driver under Linux since 2001 but it was
never included in the upstream kernel. SuSE did include the patch for mmtimer
in SLES 9. The driver has been widely used for applications on the Altix
platform.
The timer hardware was designed around the multimedia timer specification by
Intel but to my knowledge only SGI has implemented that standard. The driver
was written by Jesse Barnes.
The second revision has interrupt support removed and was somewhat simplified
by removing one include file.

[PATCH] serial-cs and unusable port size ranges
A couple of GSM GPRS PCMCIA cards advertise 16 rather than 8 port sized
windows for their serial interface. This breaks our current pcmcia serial
driver which ignores any windows that are not 8 bytes.
To avoid any regressions on other cards given this driver contains a
certain amount of "magic" the patch below looks for 8 byte windows first so
will not break existing supported cards (I hope ;))

[PATCH] fix for fsync ignoring writing errors
Currently metadata writing errors are ignored and not returned from
sys_fsync on ext2 and ext3 filesystems. That is, at least ext2 and ext3.
Both ext2 and ext3 resort to sync_inode() in their ->sync_inode method,
which in turn calls ->write_inode. ->write_inode method has void type, and
any IO errors happening inside are lost.
Make ->write_inode return the error code?

[PATCH] x86-64: sibling map fix for clustered mode
From: James Cleverdon
The value that cpuinfo returns for command 1 in ebx is the physical APIC ID
latched when the system comes out of reset.
Ordinarily, this is identical to the value in the local APIC's ID register,
because nearly all BIOSes accept the HW assigned value.
Our systems, made up of individual building blocks, can't do that. Each
node boots as a separate system and is joined together by the BIOS. Thus,
the BIOS rewrites the local APIC ID register with a new value.
Potomac and Nocona chips have a mechanism by which the BIOS writer can
change bits 7:5 to match the assigned cluster ID. Bits 2:0 come from the
thread ID. However, bits 4:3 are still those latched at reset. Oops!
Summary: Large clustered systems can't use cpuid to derive the sibling
information.
Fix: Use the local APIC ID. That's the value we use to online the CPUs, so
it had better be OK. For non-clustered systems, cpuid == local APIC, so
nothing but large boxes should be affected.

[PATCH] fix posix-timers leak
Exec fails to clean up posix-timers. This manifests itself in two ways, one
worse than the other. In the single-threaded case, it just fails to clear out
the timers on exec. POSIX says that exec clears out the timers from
timer_create (though not the setitimer ones), so it's wrong that a lingering
timer could fire after exec and kill the process with a signal it's not
expecting. In the multi-threaded case, it not only leaves lingering timers,
but it leaks them entirely when it replaces signal_struct, so they will never
be freed by the process exiting after that exec. The new per-user
RLIMIT_SIGPENDING actually limits the damage here, because a UID will fill up
its quota with leaked timers and then never be able to use timer_create again
(that's what my test program does). But if you have many many untrusted UIDs,
this leak could be considered a DoS risk.

[PATCH] x86 TSS: io port caching
There's one additional step we can do ontop of the ports-max code to get rid
of copying in X.org's case: cache the last task that set up the IO bitmap.
This means we can set the offset to invalid and keep the IO bitmap of that
task, and switch back to a valid offset (without any copying) when switching
back to that task. (or do a copy if there is another ioperm task we switch
to.)
I've attached ioport-cache-2.6.8.1.patch that implements this. When
there's a single active ioperm() using task in the system then the
context-switch overhead is very low and constant:
# ./ioperm-latency
default no ioperm: scheduling latency: 2478 cycles
turning on port 80 ioperm: scheduling latency: 2499 cycles
turning on port 65535 ioperm: scheduling latency: 2481 cycles
This single-ioperm-user situation matches 99% of the actual ioperm()
usage scenarios and gets rid of any copying whatsoever - without relying
on any fault mechanism. I can see no advantage of the GPF approach over
this patch.

[PATCH] hvc_console fix to protect hvc_write against ldisc write after hvc_close
Due to the tty ldisc code not stopping write operations against a driver
even after a tty has been closed I added a mechanism to hvc_console in my
previous patch to prevent this by nulling out the tty->driver_data in
hvc_close() but I forgot to check tty->driver_data in hvc_write(). Anton
Blanchard got several oops'es from hvc_write() accessing NULL as if it were
a pointer to an hvc_struct usually stored in tty->driver_data.
So this patch checks tty->driver_data in hvc_write() before it is used.
Hopefully once Alan Cox's patch is checked in ldisc writes won't continue
to happen after tty closes.
Anton Blanchard has tested this patch and is unable to reproduce the oops
with it applied.
Changelog:
drivers/char/hvc_console.c
- Added comment to hvc_close() to explain the reason for NULLing
tty->driver_data.
- Added check to hvc_write() to verify that tty->driver_data is valid
(NOT NULL) which would be the case if the write operation was invoked
after a tty close was initiated on the tty.

[IA64] SGI Altix hardware performance monitoring API
The SGI Altix PROM supports a SAL call for performance monitoring and for
exporting NUMA topology. We need this in community kernels for diagnostic
and performance tools to use, especially on very large machines.
This patch registers a dynamic misc device "sn_hwperf" that supports an
ioctl interface for reading/writing memory mapped registers on Altix
nodes and routers via the new SAL call. It also creates a read-only
procfs file "/proc/sgi_sn/sn_topology" to export NUMA topology and Altix
hardware inventory.
> What tools are using this?
Performance Co-Pilot http://oss.sgi.com/projects/pcp in particular,
pmshub, shubstats and linkstat. Numerous other users include anything
that needs knowledge of numa topology/interconnect in order to perform
well, e.g. mpt. BTW I have not exported any API functions .. at this
point I don't think we need any modules to call the API.

[PATCH] matroxfb update + sparse annotations
This change switches matroxfb on x86 and x86_64 from dereferencing
pointers to {read,write}[bwl], as __pa() are gone from them, and so gcc
does not need an additional register for preserving address between
consecutive {read,write}[bwl].
Then it switches only supported architecture left (ppc/ppc64/arm) from
dereferencing pointers to __raw_{read,write}[bwl].
Third part is fixing sparse complaints: add __iomem here and there, and
switch one 1bit bitfield from int to unsigned int.
After this there should be no sparse complaints in matroxfb.

siginfo_t with the idea of having the siginfo_t waitid fills in contain all
the information that wait4 or any such call could ever tell you. Nowhere
in POSIX nor anywhere else specifies this field in siginfo_t.
When Ulrich and I hashed out the system call interface we wanted, we looked
at siginfo_t and decided there was plenty of space to throw in si_rusage.
Well, it turns out we didn't check the 64-bit platforms. There struct
rusage is ridiculously large (lots of longs for things that are never in a
million years going to hit 2^32), and my changes bumped up the size of
siginfo_t. Changing that size is more trouble than it's worth.
This patch reverts the changes to the siginfo_t structure types,
and no longer provides the rusage details in SIGCHLD signal data.
Instead, I added a fifth argument to the waitid system call to fill in rusage.
waitid is the name of the POSIX function with four arguments. It might
make sense to rename the system call `waitsys' to follow SGI's system call
with the same arguments, or `wait5' in the mindless tradition. But, feh.
I just added the argument to sys_waitid, rather than worrying about
changing the name in all the tables (and choosing a new stupid name).

[IPV4]: Make fib_semantics algorithms scale better.
A singly linked list was previously used to
do fib_info object lookup for various actions
in the routing code. This does not scale very
well with many devices and even a moderate number
of routes. This was noted by Benjamin Lahaise.
To fix all of this we use 3 hash tables, two of
which grow dynamically as the number fib_info
objects increases while the final one is fixes in
size.
The statically sized table hashes on device index.
This is used for fib_sync_down, fib_sync_up, and
ip_fib_check_default.
The first dynamically sized table is keyed on
protocol, prefsrc, and priority. This is used
by fib_create_info() to look for existing fib_info
objects matching the new one being constructed.
The last dynamically sized table is keyed on
the preferred source of the route if it has one
specified. This is used by fib_sync_down when
a local address disappears.
There are still some scalability problems for
Bens test case in fib_hash.c and I will try to
attack those next.

This fixes a use-after-free bug in the context switching. A process going

itself. The problem is that when it gets around to killing itself is up to
the host and can happen a long time later, including after the incoming
process has freed its stack, and that memory is possibly being used for
something else.
The fix is to have the incoming process kill the exiting process just to
make sure it can't be running at the point that its stack is freed.

[PATCH] HVCS fix to replace yield with tty_wait_until_sent in hvcs_close
Following the same advice you gave in a recent hvc_console patch I have
modified HVCS to remove a while() { yield(); } from hvcs_close() which may
cause problems where real time scheduling is concerned and replaced it with
tty_wait_until_sent() which uses a real wait queue and is the proper method
for blocking a tty operation while waiting for data to be sent. This patch
has been tested to verify that all the paths of code that were changed were
hit during the code run and performed as expected including hotplug remove
of hvcs adapters and hangup of ttys.
- Replaced yield() in hvcs_close() with tty_wait_until_sent() to prevent
possible lockup with realtime scheduling.
- Removed hvcs_final_close() and reordered cleanup operations to prevent
discarding of pending data during an hvcs_close() call.
- Removed spinlock protection of hvcs_struct data members in
hvcs_write_room() and hvcs_chars_in_buffer() because they aren't needed.

[PATCH] blk: max_sectors tunables
Introduces two new /sys/block values:
/sys/block/*/queue/max_hw_sectors_kb
/sys/block/*/queue/max_sectors_kb
max_hw_sectors_kb is the maximum that the driver can handle and is
readonly. max_sectors_kb is the current max_sectors value and can be tuned
by root. PAGE_SIZE granularity is enforced.
It's all locking-safe and all affected layered drivers have been updated as
well. The patch has been in testing for a couple of weeks already as part
of the voluntary-preempt patches and it works just fine - people use it to

[PATCH] Add prctl to modify current->comm
This patch adds a prctl to modify current->comm as shown in /proc. This
feature was requested by KDE developers. In KDE most programs are started by
forking from a kdeinit program that already has the libraries loaded and some
other state.
Problem is to give these forked programs the proper name. It already writes
the command line in the environment (as seen in ps), but top uses a different
field in /proc/pid/status that reports current->comm. And that was always
"kdeinit" instead of the real command name. So you ended up with lots of
kdeinits in your top listing, which was not very useful.
This patch adds a new prctl PR_SET_NAME to allow a program to change its comm
field.
I considered the potential security issues of a program obscuring itself with
this interface, but I don't think it matters much because a program can
already obscure itself when the admin uses ps instead of top. In case of a
KDE desktop calling everything kdeinit is much more obfuscation than the
alternative.

[PATCH] shmem: avoid the shmem_inodes list
If we're thinking about shmem scalability... isn't it silly that each shmem
object is added to the shmem_inodes list on creation, and removed on deletion,
yet the only use for that list is in swapoff (shmem_unuse)?
Call it shmem_swaplist; shmem_writepage add inode to swaplist when first swap
allocated (usually never); shmem_delete_inode remove inode from the list after
truncating (if called before, inode could be re-added to it).
Inode can remain on the swaplist after all its pages are swapped back in, just
be lazy about it; but if shmem_unuse finds swapped count now 0, save itself
time by then removing that inode from the swaplist.

[PATCH] shmem: no sbinfo for tmpfs mount?
Some might want a tmpfs mount with the improved scalability afforded by
omitting shmem superblock accounting; or some might just want to test it in an
externally-visible tmpfs mount instance.
Adopt the convention that mount option -o nr_blocks=0,nr_inodes=0 means
without resource limits, and hence no shmem_sb_info. Not recommended for
general use, but no worse than ramfs.
Disallow remounting from unlimited to limited (no accounting has been done so
far, so no idea whether it's permissible), and from limited to unlimited
(because we'd need then to free the sbinfo, and visit each inode to reset its
i_blocks to 0: why bother?).

[PATCH] shmem: no sbinfo for shm mount
SGI investigations have shown a dramatic contrast in scalability between
anonymous memory and shmem objects. Processes building distinct shmem objects
in parallel hit heavy contention on shmem superblock stat_lock. Across 256
cpus an intensive test runs 300 times slower than anonymous.
Jack Steiner has observed that all the shmem superblock free_blocks and
free_inodes accounting is redundant in the case of the internal mount used for
SysV shared memory and for shared writable /dev/zero objects (the cases which
most concern them): it specifically declines to limit.
Based upon Brent Casavant's SHMEM_NOSBINFO patch, this instead just removes
the shmem_sb_info structure from the internal kernel mount, testing where
necessary for null sbinfo pointer. shmem_set_size moved within CONFIG_TMPFS,
its arg named "sbinfo" as elsewhere.
This brings shmem object scalability up to that of anonymous memory, in the
case where distinct processes are building (faulting to allocate) distinct
objects. It significantly improves parallel building of a shared shmem object
(that test runs 14 times faster across 256 cpus), but other issues remain in
that case: to be addressed in later patches.

[PATCH] shmem: inodes and links need lowmem
Keith Mannthey's Bugzilla #3268 drew attention to how tmpfs inodes and
dentries and long names and radix-tree nodes pin lowmem. Assuming about 1k of
lowmem per inode, we need to lower the default nr_inodes limit on machines
with significant highmem.
Be conservative, but more generous than in the original patch to Keith: limit
to number of lowmem pages, which works out around 200,000 on i386. Easily
overridden by giving the nr_inodes= mount option: those who want to sail
closer to the rocks should be allowed to do so.
Notice how tmpfs dentries cannot be reclaimed in the way that disk-based
dentries can: so even hard links need to be costed. They are cheaper than
inodes, but easier all round to charge the same. This way, the limit for hard
links is equally visible through "df -i": but expect occasional bugreports
that tmpfs links are being treated like this.
Would have been simpler just to move the free_inodes accounting from
shmem_delete_inode to shmem_unlink; but that would lose the charge on unlinked
but open files.

[PATCH] ppc64: improved VSID allocation algorithm
This patch has been tested both on SLB and segment table machines. This
new approach is far from the final word in VSID/context allocation, but
it's a noticeable improvement on the old method.
Replace the VSID allocation algorithm. The new algorithm first generates a
36-bit "proto-VSID" (with 0xfffffffff reserved). For kernel addresses this
is equal to the ESID (address >> 28), for user addresses it is:
(context << 15) | (esid & 0x7fff)
These are distinguishable from kernel proto-VSIDs because the top bit is
clear. Proto-VSIDs with the top two bits equal to 0b10 are reserved for
now.
The proto-VSIDs are then scrambled into real VSIDs with the multiplicative
hash:
VSID = (proto-VSID * VSID_MULTIPLIER) % VSID_MODULUS
where VSID_MULTIPLIER = 268435399 = 0xFFFFFC7
VSID_MODULUS = 2^36-1 = 0xFFFFFFFFF
This scramble is 1:1, because VSID_MULTIPLIER and VSID_MODULUS are co-prime
since VSID_MULTIPLIER is prime (the largest 28-bit prime, in fact).
This scheme has a number of advantages over the old one:
- We now have VSIDs for every kernel address (i.e. everything above
0xC000000000000000), except the very top segment. That simplifies a
number of things.
- We allow for 15 significant bits of ESID for user addresses with 20
bits of context. i.e. 8T (43 bits) of address space for up to 1M
contexts, significantly more than the old method (although we will need
changes in the hash path and context allocation to take advantage of
this).
- Because we use a real multiplicative hash function, we have better and
more robust hash scattering with this VSID algorithm (at least based on
some initial results).
Because the MODULUS is 2^n-1 we can use a trick to compute it efficiently
without a divide or extra multiply. This makes the new algorithm barely
slower than the old one.

[PATCH] ppc64: lparcfg fixes for processor counts
This patch corrects how the lparcfg interface was presenting the number of
active and potential processors. (As reported in LTC bugzilla number 10889).
- Correct output for partition_potential_processors and
system_active_processors.
- suppress pool related values in scenarios where they do not make
sense. (non-shared processor configurations)
- Display pool_capacity as a percentage, to match the behavior from
iSeries code.

[NET] generalise per protocol slab cache handling
With this patch we get two new slabcaches, for sctp socks, that previously
were being allocated on the default, that was tcp[6]_sock, i.e. wasting 288
bytes per sock in the IPv4 case and 256 bytes for the IPv6 version, this is in
preparation for DCCP (or any other new protocol :) ).
With this in place another nice side effect that is easier to achieve is to
get rid of struct sock sk->sk_slab, and instead use sk->sk_prot->slab, saving
sizeof(void *) on every struct sock instance, but this unfortunatly has to
wait for the conversion of all protocols that use per socket slabcaches to
use sk->sk_prot, AF_UNIX is the only one AFAIK, so I'll try to convert it to
use sk->sk_prot and then get rid of sk->sk_slab.
As for the protocols that don't use per socket slabcaches its just a matter
of defaulting to sk_cachep at sk_free time if sk->sk_prot is NULL.

Now, we only add a suspend event to a users queue and increment
suspends_pending if the user isn't already in the middle of
handling a suspend event.

[IPV6]: Add option to copy DSCP in decap in ip6_tunnel.
Here is a patch that allows the copying of the DSCP during decapsulation

may be asymmetric. It also means that we preserve compatibility should
anyone be relying on the current behaviour.
inet_ecn.h might appear to be an odd place for ipv6_copy_dscp, but
I couldn't put it in dsfield.h since I want to use ipv6_get_dsfield
