However, ftrace is not # necessarily active when such crashes occur. # # The kernel OOPS sometimes follows a warning from ftrace indicating that # some module functions could not be patched with a nop. Other times, if a # module is loaded early during boot, instruction patching can fail due to # a separate bug, but the error is not reported due to missing error # reporting. # # In all the above cases when instruction patching fails, ftrace will be # disabled but certain kernel module functions will be left with default # calls to _mcount(). This is not a problem with ELFv1. However, with # -mprofile-kernel, the default stub is problematic since it depends on a # valid module TOC in r2. If the kernel (or a different module) calls into # a function that does not use the TOC, the function won't have a prologue # to setup the module TOC. When that function calls into _mcount(), we # will end up in the relocation stub that will use the previous TOC, and # end up trying to jump into a random location. From the above trace: # # iomap_apply+0x20c/0x920 [kernel TOC] # | # V # ext4_iomap_end+0x8/0x30 [no GEP == kernel TOC] # | # V # _mcount() stub # [uses kernel TOC -> random entry] # # To address this, let's change over to using the special stub that is # used for ftrace_[regs_]caller() for _mcount(). This ensures that we are # not dependent on a valid module TOC in r2 for default _mcount() # handling. # # Reported-by: Qian Cai # Signed-off-by: Naveen N.
