Segmentation faults in nginx with 3.1-201510012203

[PaX Team]

do you have UDEREF enabled as well? if yes, which one gets activated? (or you can just post dmesg and cpufinfo)

[kamil]

I can confirm that 4.2.3 is unbootable with my config due to udevadm and init crashes, but it looks like a separate issue - happens even with uderef disabled (in fact with all grsec/pax options disabled) and crashes are consistent (same RIP/fault address)

Dmesg:

Sorry, wrong log, this one shows udev crash:

yes, that's the vsyscall page and its emulation which i changed recently to basically enforce vsyscall=none. can you try to boot a vanilla 4.2 kernel with that option to confirm that it fails the same way?

edit: false alarm, it's not the vsyscall page but the paravirt clock one, let me fix it.

Sure, I can check, but to be honest I'm more interested in the 3.14.54 issue Any ideas about that?

UDEREF was not enabled on no one machine!
If you really need the dmesg, I have to search for them in the log files.

UDEREF was not enabled on no one machine!

yes please, i'll need to see what exactly those faults look like. also can you try to boot with 'nopcid' on the kernel command line and see if anything changes?

PS: please open a new thread and let's continue this there.

Vanilla with vsyscall=none also fails to boot, but crashes in different places:

Sure, I can check, but to be honest I'm more interested in the 3.14.54 issue Any ideas about that?

i asked about newer kernels because i hoped that maybe the recent pcid refactoring in there uncovered such latent bugs too (the latest PaX patch should fix your boot issue now btw). as for 3.14, i haven't changed any uderef/pcid code there between .53 and .54 so i'll have to devise a plan to figure it out.

Nope, still crashes with test8:

Ok, let me know if I can help.
BTW Just checked that booting with pax_nouderef does not help if UDEREF is compiled in.

Best regard.

[PaX Team]

i finally figured it out, it's a regression on the PaX side that crept in due to the recent NMI fixes upstream, the next patch will fix it and thanks for your patience!

Oh, so RBX got trashed on NMI, that might explain those strange crashes

I can confirm that it's fixed in 3.14.54-201510152119 - thanks!

Best regards.

[jorgus]

Is this problem fully resolved? I booted an old physical machine (Core2 Duo E6750) with 3.14.54 + grsecurity-3.1-3.14.54-201510152119.patch and basic binaries started segfaulting. It works as expected under 3.14.53 + grsecurity-3.1-3.14.53-201509212108.patch.

[PaX Team]

yes, the NMI related breakage should be fixed. do you also have UDEREF? if so, which kind gets enabled? does disabling UDEREF/KERNEXEC change the behaviour? also dmesg/config may be helpful...

Weak one. With uderef disabled at command line it still crashed. Just installed 3.14.55 - no change. The last one working was 3.14.53.
