Revision 8c9ce89c5b63028dd3be43807f10b009cd2c6e51 authored by Masahiro Yamada on 30 May 2022, 09:01:38 UTC, committed by Masahiro Yamada on 04 June 2022, 21:20:57 UTC
mod->name is set to the ELF filename with the suffix ".o" stripped.
The current code calls strdup() and free() to manipulate the string,
but a simpler approach is to pass new_module() with the name length
subtracted by 2.
Also, check if the passed filename ends with ".o" before stripping it.
The current code blindly chops the suffix:
tmp[strlen(tmp) - 2] = '\0'
It will cause buffer under-run if strlen(tmp) < 2;
