Post #1 of 8 (4062 views) Permalink x86_64 segfault error codes For linux kernel segfault error 4 segfault error codes on x86_64, bits 0-3 are documented in segfault error 6 arch/x86_64/mm/fault.c. However, I am getting error 0x14 and 0x15 with this particular user app when segfault at 0 ip sp error 4 it segfaults. Is bit 4 valid and what does that imply? xxx-001[2085]: segfault at 0000007f960ea86b rip 0000007f960ea86b rsp 0000007fbfffe968 error 14 xxx-001[2091]: segfault at 0000007fbfffe670 segfault at rip rsp error 6 rip 0000007fbfffe670 rsp 0000007fbfffe668 error 15 -- -= Dave =- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo [at] vger More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ ak at suse Dec14,2005,10:31AM Post #2 of 8 (4029 views)
Segfault Error Codes
Permalink Re: x86_64 segfault error codes [In reply to] Dave
you get. So you have a message like the following: segfault at bfea3fec ip 080ee07e sp bfea3fa0 error 6 You might already know that ip means instruction pointer and sp means
Segfault Error 15
stack pointer and as such the addresses that follow them are the values in dmesg segfault error 4 those registers. But what does the error number mean? The error number, or code, actually gives you a better explanation of libc 2.12 so segfault error 4 what the cause of the segfault is. The number's bits are flags describing the error and are architecture-dependent. For x86/x86_64 I just wrote an online converter/decoder that you can use to explain the segfault http://www.gossamer-threads.com/lists/linux/kernel/598127 error code. As an example, the above error code is explained as: The cause was a user-mode write resulting in no page being found. And the common error 4: The cause was a user-mode read resulting in no page being found.(also known as a null pointer dereference). Enjoy.
