* futex_cmpxchg_enabled not set in futex_init on pentium3 @ 2009-11-29 17:46 Joseph Parmelee 2009-11-30 21:36 ` Darren Hart 0 siblings, 1 reply; 12+ messages in thread From: Joseph Parmelee @ 2009-11-29 17:46 UTC (permalink / raw) To: linux-kernel Greetings all: Sometime between 2.6.28.6 and 2.6.31.5 a regression (feature?) in the futex system now causes futex test failures on glibc-2.9 which where not present before. That is, recompiling the binaries of glibc-2.9 and rerunning its test suite now produces futex errors that passed previously. The problem appears now with glibc-2.9 compiled with either gcc-4.1.2 or gcc-4.4.2, and with glibc-2.11 compiled with gcc-4.4.2, which is what I am currently running on this machine, failures and all. The system under discussion is a uniprocessor pentium3 with an AMI BIOS. Full details available on request should that prove necessary. I have tracked the test failures down to the fact that futex_cmpxchg_enabled is not set because the test in futex_init now "fails" (actually succeeds). This appears to be happening because the expected page fault intentionally provoked by a null dereference appears to be working now in kernel mode. This *may* (rank speculation) be associated with the AMI BIOS low-memory corruption protection added sometime during this gap, and which is activated on this machine. Before I muck any further with this, especially involving the quite tricky futex mess, I would appreciate some insight into the idea behind the test in futex_init. I don't understand why you would bother to invoke a fault in what is apparently a test to determine if the cmpxchg instruction works. The fault is supposed to occur as a result of a null dereference that takes place *before* the cmpxchg instruction is even executed. If you want to test that cmpxchg works, why not just make a little test in futex_init that uses it and fails (not succeeds) if it doesn't behave as expected, or if there is a fault of some kind (like illegal instruction)? Or is the fact that we don't get a fault the whole point here?

I suspect this is because the test asks for a userspace address. So rather than hack something up to use a real userspace address, we just send NULL.

Can you please printk the return value of that cmpxchg() test and provide a full bootlog (dmesg) of your machine ?

The point is that we have to deal with architectures where we do not know at compile time whether we actually have a working cmpxchg. So we use cmpxchg with a NULL pointer which is supposed to fault and return -EFAULT and if cmpxchg is not working on the machine the arch code is supposed to return -ENOSYS. See arch/x86/include/asm/futex.h:futex_atomic_cmpxchg_inatomic() for an example. > I suspect this is because the test asks for a userspace address.

We have no real user space address at this point. > > The fault is supposed to occur as a result of a null dereference that takes > > place *before* the cmpxchg instruction is even executed. If you want to No, the fault happens _when_ cmpxchg is executed on the NULL pointer. > > test that cmpxchg works, why not just make a little test in futex_init that > > uses it and fails (not succeeds) if it doesn't behave as expected, or if > > there is a fault of some kind (like illegal instruction)? Or is the fact > > that we don't get a fault the whole point here? Again, we expect it to fault. IIRC, we tried to use a valid address for the test and let the exception fixup code return -EFAULT when the instruction is not available. That worked on x86 but did not work on other archs.

Thanks for the responses, which verify that my understanding of the expected behavior was correct. That means that we have a real bug. Attached is the complete output of dmesg from the most recent boot run. This line due to added printk in futex_init: [ 0.147626] futex_init curval = F0006AA0 These lines due to added printk's in arch/x86/include/asm/futex.h:futex_atomic_cmpxchg_inatomic(). [ 0.147384] cmpxchg: ax before=cf80e000, ax after=f0006aa0 [ 0.147444] cmpxchg: bx before=0, bx after=0 [ 0.147536] cmpxchg: cx before=0, cx after=0 The compiler generates cmpxchg %ecx,(%ebx), so I added extended asm to dump the registers involved just before and after the cmpxchg into variables for printk. All is consistent with the fact that the fault is not occurring and the cmpxchg is working "as expected" at address 0. Examining /proc/kcore with gdb shows that address c0000000 contains f0006aa0. Direct access with gdb to address 0 fails as expected. To completely eliminate any possibility that the fault was getting lost in the fixup code somehow, I removed all the fixup code from the cmpxchg extended asm, and the results are exactly the same. In fact this run is with the fixup code removed. The fault is not occurring. > That'd be a serious bug as it would let every NULL pointer dereference > in the kernel proceed. Interestingly, a printk inserted in futex_init that attempts a null dereference results in an oops as expected. > > Could you also please do a quick check in which kernel version this > got introduced ? This was known to be working in 2.6.28.6. Unfortunately, I didn't find it until I updated glibc and ran its test suite on 2.6.31.5. However, I have been noticing some nasty log messages about page allocation failures in pppd with plenty of available memory starting from sometime in the 2.6.31 series. One of them is also attached FWIW. But these didn't seem to be causing any problems other than making me nervous. I am located in the mountains of Costa Rica with only a very slow dialup, so git bisect is not an option for me. But I do have old copies of vmlinuz lying around that go back to the 2.6.29 series. Unfortunately, I don't have the matching unstripped vmlinux which would allow debugging, but I might be able to test other ways. I will post again as soon as I have something. In the meantime, if you can think of any tests that you want to run, I will be most happy to help.

I needed to reinstall the old glibc because the new glibc-2.11 wants kernels in the 2.6.31 series or later. The problem first appears in 2.6.31 and persists through the current 2.6.31.6.

Using gdb on /proc/kcore, 2.6.32 no longer allows access to 0xc0000000, which could be accessed in 2.6.31.x, presumably showing the 16-bit real-mode interrupt address table set up by the BIOS at physical address zero. But .... (see 3). 2. Disabling the AMI BIOS corruption prevention in 2.6.32 had no effect on the behavior described in 3 below. 3. In 2.6.31.x the following inserted in futex_atomic_cmpxchg_inatomic() in futex.h caused an oops. It now works in 2.6.32. printk(KERN_INFO "*uaddr=%x, oldval=%x, newval=%x", *uaddr, oldval, newval); Producing in dmesg: [ 0.149408] *uaddr=f0006aa0, oldval=0, newval=0 The following also works in futex_init in futex.c: unsigned int testval, *nullptr=NULL; testval=*(unsigned int *)NULL; printk(KERN_INFO "curval=%x testval=%x", curval, testval); printk(KERN_INFO "An explicit null dereference=%x", *(unsigned int *)NULL); printk(KERN_INFO "An implicit null dereference=%x", *nullptr); Producing in dmesg: [ 0.149466] curval=f0006aa0 testval=f0006aa0 [ 0.149557] An explicit null dereference=f0006aa0 [ 0.149648] An implicit null dereference=f0006aa0 Thus it is completely clear that the virtual zero page is mapped, probably to physical zero, during this phase of kernel initialization. I have used 2.6.32 for only one day, but so far see no ill effects from this other than the lack of those futex functions which rely on a null pointer dereference fault to set futex_cmpxchg_enabled. If zero-page mapping is now "normal", the test in futex.c for cmpxchg functionality must be changed. I have "fixed" this on our intel machines by simply commenting out the test of curval in futex_init, thus causing futex_cmpxchg_enabled to be unconditionally set. Not suitable for prime-time obviously, but "it works for us" until somebody with more savvy comes up with a real fix. Yours, Joseph ^ permalink raw reply [flat|nested] 12+ messages in thread

The value returned for curval in futex_init is still the same 0xf0006aa0, and thus as before futex_cmpxchg_enabled is not set, thus causing many kernel futex syscalls to return -ENOSYS incorrectly, the proximate cause of the glibc test failures.
