Subject: [PATCH 01/32] Handle CPU interrupts by inline checking of a flag
Fix the nasty TCG race conditions and crashes by implementing cpu_exit
as setting a flag which is checked at the start of each TB. This is
slightly slower than the attempt to have cpu_exit alter the graph of
TBs, but it doesn't crash if a thread or signal handler calls cpu_exit
while the execution thread is itself modifying the TB graph.
This version of the patch includes command line option "-no-stopflag"
which reverts to the previous racy behaviour. This is intended for
convenience in testing and comparative benchmarking and won't be
in the final patch.
It's probably worth experimenting with whether the flag-testing
code has the branch in a sense which confuses branch-prediction
and thus whether flipping it might change performance.
Mostly this needs benchmarking to determine what the actual speed
hit is, which I never got round to. Feel free to do some :-)

Subject: [PATCH 02/32] linux-user: fix QEMU_STRACE=1 segfault
While debugging some issues with QEMU_STRACE I stumbled over segmentation
faults that were pretty reproducible. Turns out we tried to treat a
normal return value as errno, resulting in an access over array boundaries
for the resolution.
Fix this by allowing failure to resolve invalid errnos into strings.

- propagate fault further down, so we display the negative value

Subject: [PATCH 03/32] linux-user: save auxv length
We create our own AUXV segment on stack and save a pointer to it.
However we don't save the length of it, so any code that wants to
do anything useful with it later on has to walk it again.
Instead, let's remember the length of our AUXV segment. This
simplifies later uses by a lot.

Subject: [PATCH 05/32] linux-user: fake /proc/self/maps
glibc's pthread_attr_getstack tries to find the stack range from
/proc/self/maps. Unfortunately, /proc is usually the host's /proc
which means linux-user guests see qemu's stack there.
Fake the file with a constructed maps entry that exposes the guest's
stack range.

Subject: [PATCH 06/32] linux-user: fake /proc/self/stat
The boehm gc finds the program's stack starting pointer by
checking /proc/self/stat. Unfortunately, so far it reads
qemu's stack pointer which clearly is wrong.
So let's instead fake the file so the guest program sees the
right address.

Subject: [PATCH 07/32] linux-user: fake /proc/self/auxv
Gtk tries to read /proc/self/auxv to find its auxv table instead of
taking it from its own program memory space.
However, when running with linux-user, we see the host's auxv which
clearly exposes wrong information. so let's instead expose the guest
memory backed auxv tables via /proc/self/auxv as well.

Subject: [PATCH 09/32] linux-user: fix wait* syscall status returns
When calling wait4 or waitpid with a status pointer and WNOHANG, the
syscall can potentially not modify the status pointer input. Now if we
have guest code like:
int status = 0;
waitpid(pid, &status, WNOHANG);
if (status)
<breakage>
then we have to make sure that in case status did not change we actually
return the guest's initialized status variable instead of our own uninitialized.
We fail to do so today, as we proxy everything through an uninitialized status
variable which for me ended up always containing the last error code.
This patch fixes some test cases when building yast2-core in OBS for ARM.

When executing 32-bit guest binaries on 64-bit hosts, mmap() can return
a 64-bit pointer. Tell mmap() to always map in 32-bit address space, so
we make 32-bit guest applications happy.
This is a hack and should not go upstream in its current form!

Subject: [PATCH 12/32] linux-user: Fix 32-on-64 mmap for x86_64
When running a 32 bit guest on a 64 bit host, we can run into trouble while
calling the host's mmap() because it could potentially give us a 64 bit
return value which the guest can't interpret.
There are 2 ways of dealing with this:
1) Only do MAP_FIXED mmap calls and implement our own vm management in QEMU
2) Tell the kernel that we only want mappings in the lower 32 bits
Way 1 is very involved and hard to do. It's been advocated forever now but
nobody sat down to actually implement it.
Way 2 is easy. It's what this patch does. However, it only works on x86_64
because that's the only platform implementing the MAP_32BIT flag. Since most
people are on x86_64 though, I think it's a good enough compromise for now
though

Subject: [PATCH 16/32] linux-user: map lower in address space
While trying to compile Java I can into situations where there was simply
no virtual address space left for a 32-bit guest to take. For example when
Java tried to allocate 1GB of heap.
Part of the problem is that we're starting to map things at 0x40000000.
This is a bit high. Taking that number down would give us a lot of free
virtual address space which means we'd be able to squeeze more stuff in.

Subject: [PATCH] linux-user: fix openat
When running openat using qemu-arm, we stumbled over invalid permissions
on the created files. The reason for this is that the mode parameter gets
treates as an O_... flag, which it isn't - it's a permission bitmask.
This patch removes the needless translation of the mode parameter,
rendering permission passing of openat() to work with linux-user.

From: Alexander Graf <agraf@suse.de>
For OBS, we're running a full cross-guest inside of a VM. When a build
is done there, we reboot the guest as shutdown mechanism.
Unfortunately, reboot is not implemented in linux-user. So this mechanism
fails, spilling unpretty warnings. This patch implements sys_reboot()
emulation.

Subject: [PATCH 25/32] qemu-cvs-ioctl_nodirection
the direction given in the ioctl should be correct so we can assume the
communication is uni-directional. The alsa developers did not like this
concept though and declared ioctls IOC_R and IOC_W even though they were
IOC_RW.

Tested and used for several years by GNS3, it doesn't break the build.
I could not access http://git.qemu.org/qemu.git/plain/CODING_STYLE and
http://git.qemu.org/qemu.git/plain/HACKING (404) so these patches may
not be 100% conform. The script didn't report any error though.

[agraf] I combined the upstream submitted mail header with the 0.14 Uli
version of the patch. If this isn't upstream by 1.1, remove in
the next round!

When using qemu's linux-user binaries through binfmt, argv[0] gets lost
along the execution because qemu only gets passed in the full file name

Subject: [PATCH 31/32] linux-user: Ignore timer_create syscall
We don't implement the timer_create syscall, but shouting out loud
about it breaks some %check tests in OBS, so better ignore it silently.

Subject: [PATCH 32/32] linux-user: be silent about capget failures
Complaining about capget doesn't buy us anything, but makes %check
fail in certain builds. So better not complain about its missing
implementation and go on with life :)
