[PATCH] uml: fix critical IP checksum corruption
From: Lars Ellenberg <Lars.Ellenberg@linbit.com>
Add a memory barrier to the assembly checksum code - the code was copied
straight from the i386 one, and the patch resyncs the code with the
original. I'll check if the original code can be included directly (i.e.
"#include") after 2.6.9.
Without this patch, every 2.6 UML release corrupts the checksum of every
UDP fragmented packet with size >= MTU (verified by various people, we all
agree on this issue; nobody reported "Works fine here"). The corrupted
packets are not accepted, thus blocking any kind of communication with
large-sized UDP packets.
In fact, I've even dissected the UML -> host traffic before and after this
patch with Ethereal - and it always reported an incorrect checksum for
fragmented UDP packets before and always correct after applying the patch.

[PATCH] uml: use always a separate io thread for UBD
Currently, ubd=sync is different from replacing ubd#= with ubd#s=. This is
against Principle of Least Surprise, so remove this difference.
Also the current ubd=sync behaviour is completely useless: it is to make sure
that when the kernel has synched its I/O to the virtual disk, the host does
not invalidate this with his caching; this causes ReiserFS corruption.
But since actually we call end_request() only after the io_thread has done its
work, we never lie to the block layer. Using O_SYNC as we do when replacing
ubd#= with ubd#s= is enough.

[PATCH] uml: fix ubd deadlock on SMP
From: BlaisorBlade <blaisorblade_spam@yahoo.it>, Chris Wright <chrisw@osdl.org>
Avoid deadlocking onto the request lock in the UBD driver, i.e. don't lock
the queue spinlock when called from the request function.
In detail:
Rename ubd_finish() to __ubd_finish() and remove ubd_io_lock from it. Add
wrapper, ubd_finish(), which grabs lock before calling __ubd_finish(). Update
do_ubd_request to use the lock free __ubd_finish() to avoid deadlock. Also,
apparently prepare_request is called with ubd_io_lock held, so remove locks
there.

[PATCH] SELinux: fix bugs in mprotect hook
The patch below by Roland McGrath fixes two bugs in the implementation of
the selinux_file_mprotect hook:
It calls selinux_file_mmap, which has two problems. First, the stacked
security module will get both mmap and mprotect callbacks for an
mprotect call, which is wrong. Secondly, the vm_flags value contains
VM_* bits, and these do not match the MAP_* bits of the same name or
function, so it passes bogus flags and causes every mprotect to be
treated as if MAP_SHARED were in use.
The patch shares the common code while not having one function call the
other, and fixes these two bugs.

[PATCH] Fix reporting of process start times
Derive process start times from the posix_clock_monotonic notion of uptime
instead of "jiffies", consistent with the earlier change to /proc/uptime
itself.
(http://linus.bkbits.net:8080/linux-2.5/cset@3ef4851dGg0fxX58R9Zv8SIq9fzNmQ?na%0Av=index.html|src/.|src/fs|src/fs/proc|related/fs/proc/proc_misc.c)
Process start times are reported to userspace in units of 1/USER_HZ since
boot, thus applications as procps need the value of "uptime" to convert
them into absolute time.
Currently "uptime" is derived from an ntp-corrected time base, but process
start time is derived from the free-running "jiffies" counter. This
results in inaccurate, drifting process start times as seen by the user,
even if the exported number stays constant, because the users notion of
"jiffies" changes in time.
It's John Stultz's patch anyways, which I only messed up a bit, but since
people started trading signed-off lines on lkml:

[PATCH] m32r: remove obsolete system calls
This patch is for removing obsolete system calls from m32r kernel, such as
old_mmap and old_select.
* arch/m32r/kernel/entry.S:
- Remove an obsolete system call, old_mmap, from the syscall table.
* arch/m32r/kernel/sys_m32r.c:
- Remove obsolete system calls, old_mmap() and old_select().
- do_mmap2() is renamed to sys_mmap2().
* CAUTION (for m32r users):
The new kernel (applied this patch) does not have a backward
compatibility. The new kernel and old library pair does not work.
So, those who want to use the new kernel must use a new version of
glibc (the GNU C library), which uses the "mmap2(_NR_mmap2)" syscall
for __mmap() instead of the "old_mmap(__NR_mmap)".
The new glibc package, libc6_2.3.2.ds1-16.0.3_m32r.deb, is provided
on the following site, please apt-get/download it and upgrade.
