No it's not a kernel bug. #include <stdio.h> int main(void) { printf("%d\n", *(int*)1ULL); return 0; } The report varies with chosen address; (0x1ULLL): [507330.709345] a.out[14257]: segfault at 1 ip 000000000040052d sp 00007fff7d83ae10 error 4 in a.out[400000+1000] (0x8000000000000000ULL): [507297.331443] a.out[14238] general protection ip:400532 sp:7fffe3ebe5d0 error:0 in a.out[400000+1000] in neither case the kernel is at fault. JFYI, on x86, /* * Page fault error code bits: * * bit 0 == 0: no page found 1: protection fault * bit 1 == 0: read access 1: write access * bit 2 == 0: kernel-mode access 1: user-mode access * bit 3 == 1: use of reserved bit detected * bit 4 == 1: fault was an instruction fetch */ -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
