GDB is telling me that the fault is in get_current(). If that were broken, your system would be very much misbehaving.

I suppose you were using the vmlinux from a newer kernel. gdb tells me the same thing with my latest builds but it seems code layout has changed a bit since 2.5.31.5-0.1-desktop. Alright, manual decoding fun! 4c 89 fe mov %r15, %rsi 65 48 8b 3c 25 00 b0 mov %gs:0xb0, %rdi 00 00 ## sa.base.error = aa_may_change_ptraced_domain(current, new_profile) e8 cf f5 ff ff callq aa_may_change_ptraced_domain ## if (sa.base.error) 85 c0 test %eax, %eax ## <actually save retval to sa.base.error> 89 85 6c ff ff ff mov %eax,-0x94(%rbp) ## goto audit; 0f 85 25 fe ff ff jne -507 ## <otherwise continue elsewhere> e9 ee fe ff ff jmpq -274 ## dang, unrelated line of control from here ## if (profile || profile->flags & PFLAG_IX_ON_NAME_ERROR) on line 251 <41> f6 45 68 08 testb $0x8,0x68(%r13) where %r13 is NULL. I don't know the code at all but it looks like it should have been "if (profile && profile->flags & ...)" instead of "profile ||". Reassigning to agruen. BTW, how do I get vmlinux w/ debug info for specific kernel version?
