Hi everyone, I wrote a small kernel module where I trigger a page fault by writing to an invalid memory address. This causes an Oops that prints the associated Stack Trace, but contrary to what the kernel documentation claims, I get no VA next to each function in the Call Trace:
Call Trace: do_one_initcall+0xfc/0x290 ? cache_alloc_debugcheck_after+0x38/0x270 ? rcu_read_lock_sched_held+0x77/0xa0 ? kmem_cache_alloc_trace+0x2b6/0x330 do_init_module+0x4b/0x1b6 load_module+0x2140/0x24c0 ? find_held_lock+0x2d/0xa0 sys_init_module+0xdd/0x100 do_int80_syscall_32+0x73/0x170 entry_INT80_32+0xcf/0xcf This looks very much unlike what I see in https://www.kernel.org/doc/html/v4.11/admin-guide/bug-hunting.html I was wondering maybe the reason is that I didn't compile the kernel with the right debug options, but a quick glance at the .config file reveals they all seem to be there: CONFIG_DEBUG_INFO=y CONFIG_STACKTRACE=y CONFIG_DEBUG_BUGVERBOSE=y Cheers, Adrian _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
