1. Various problems with futex
2. Test attached shows errors:
FUTEX_WAKE_OP arg4 not decoded correctly in 32-bit (looks like fixed in linux-2.6.32.3)
FUTEX_LOCK_PI(_PRIVATE) with non-NULL timeout returns ETIMEDOUT immediately without waiting (may be fixed in linux-2.6.32.3)
FUTEX_WAIT_BITSET(_PRIVATE) with non-NULL timeout returns ETIMEDOUT immediately without waiting (patch suggested below)
Definitions of FUTEX_WAIT_BITSET_PRIVATE and FUTEX_WAKE_BITSET_PRIVATE were bad in header file (fixed in linux-2.6.32.3)
Definition of FUTEX_OP unsafe if actual arguments are expressions (safe one suggested below)
3. futex

Here is the output from the attached test compiled with -m32 and run under 64-bit Linux 2.6.27.39.
Could not find undodb private space
FUTEX_WAKE_PRIVATE with bad address succeeds
FUTEX_WAKE with zero val woke a process
FUTEX_WAKE with negative val woke a process
FUTEX_REQUEUE returns 1 when waking no processes but requeueing one

KERNELBUG? FUTEX_WAIT_BITSET with timer returns ETIMEDOUT immediately
KERNELBUG? FUTEX_WAIT_BITSET_PRIVATE with timer returns ETIMEDOUT immediately
Test succeeded
If compiled in 64-bit mode the output is the same but without the line about FUTEX_WAKE_OP.
Here is the output again with my comments.
>>>Could not find undodb private space
Nothing to do with the kernel: it prints this if it isn't running under our debugger.
>>>FUTEX_WAKE_PRIVATE with bad address succeeds
It isn't clear that this is a bug. FUTEX_WAKE always returns -EFAULT with a bad uaddr, because it looks for the vma and doesn't find one. FUTEX_WAIT_PRIVATE only does access_ok(), which is a weak test on x86 architecture. On 32-bit FUTEX_WAKE_PRIVATE always returns 0 because it doesn't find a waiter: on 64-bit it returns -EFAULT if uaddr is negative and otherwise 0. I can see the case for not doing a proper accessibility check since the kernel doesn't actually dereference uaddr for FUTEX_WAKE, but the existing behaviour is a bit inconsistent.
>>>FUTEX_WAKE with zero val woke a process
>>>FUTEX_WAKE with negative val woke a process
>>>FUTEX_REQUEUE returns 1 when waking no processes but requeueing one
These messages are because the kernel doesn't do what the man page says it does. Maybe the man page is wrong.... The treatment of counts of processes to be woken or requeued is a bit inconsistent. Sometimes you wake a process before checking the count (so a zero or negative count is treated as 1) and sometimes you check the count first. Maybe there's some method in your madness, but if so the man page is wrong.
>>>KERNELBUG? FUTEX_WAKE_OP arg4 not decoded correctly in 32-bit
Should already have been fixed by this diff in futex_compat.c from 2.6.27.39 to 2.6.32.3

>>>KERNELBUG? FUTEX_LOCK_PI_PRIVATE with timer returns ETIMEDOUT immediately
The problem was in rtmutex.c. The code has changed, so it may be fixed now.
>>>KERNELBUG? FUTEX_WAIT_BITSET with timer returns ETIMEDOUT immediately
>>>KERNELBUG? FUTEX_WAIT_BITSET_PRIVATE with timer returns ETIMEDOUT immediately
This doesn't seem to be fixed yet. I think it should be fixed by this diff to futex.c in version linux-2.6.32.3.

The same change is needed for futex_compat.c.

>>>Test succeeded
It didn't find any problems that it didn't expect.
Definitions of FUTEX_WAIT_BITSET_PRIVATE and FUTEX_WAKE_BITSET_PRIVATE were bad in linux/futex.h, but have been fixed in linux-2.6.32.3.
The definition of FUTEX_OP in linux/futex.h doesn't protect against the actual arguments being expressions. Here is a safer one
#define FUTEX_OP(op, oparg, cmp, cmparg) \
((((op) & 0xf) << 28) | (((cmp) & 0xf) << 24) \
| (((oparg) & 0xfff) << 12) | ((cmparg) & 0xfff))

Hi Richard,
Thomas, Ingo - should we push commit
f8d1e548931cfa5ea9a082e020c2a47d27e5d793 to stable? (I didn't see
[email protected] in the -tip commit for this patch).

Right, fixed in commit f54f098612d7f86463b5fb4763d03533d634de73. This
has already been sent to [email protected].

Both of the above are due to the testcase using a relative timeout which
is only appropriate for the FUTEX_WAIT opcode. The newer opcodes use an
absolute timeout. This was done for syscall restart optimizations, but
FUTEX_WAIT could not be changed as it was already "out in the wild".
Additionally, FUTEX_WAIT_BITSET and FUTEX_WAIT_REQUEUE_PI can also take
FUTEX_CLOCK_REALTIME as a flag to the futex op which identifies the
passed in timeout to be generated from CLOCK_REALTIME instead of
CLOCK_MONOTONIC.

Right, fixed in commit f8d1e548931cfa5ea9a082e020c2a47d27e5d793.

That seems reasonable, please consider submitting a patch.

>>>> FUTEX_WAKE_PRIVATE with bad address succeeds
> It isn't clear that this is a bug. FUTEX_WAKE always returns -EFAULT
with a bad uaddr, because it looks for the vma and doesn't find one.
FUTEX_WAIT_PRIVATE only does access_ok(), which is a weak test on x86
architecture. On 32-bit FUTEX_WAKE_PRIVATE always returns 0 because it
doesn't find a waiter: on 64-bit it returns -EFAULT if uaddr is negative
and otherwise 0. I can see the case for not doing a proper accessibility
check since the kernel doesn't actually dereference uaddr for
FUTEX_WAKE, but the existing behaviour is a bit inconsistent.

> These messages are because the kernel doesn't do what the man page
says it does. Maybe the man page is wrong.... The treatment of counts of
processes to be woken or requeued is a bit inconsistent. Sometimes you
wake a process before checking the count (so a zero or negative count is
treated as 1) and sometimes you check the count first. Maybe there's
some method in your madness, but if so the man page is wrong.
