Hello, im using elfutils in ABRT program specifically when generating core_backtrace. According to this https://github.com/abrt/abrt/issues/890 post, it is not a good idea using elfutils under root. So I have tried moving as much elfutils function calls to non-root process as possible. That means the parent process is forked and in child process there are opened necessary files:
https://github.com/xsulca00/abrt/blob/iss%23890/src/hooks/abrt-hook-ccpp.c#L1321 https://github.com/xsulca00/satyr/blob/iss%23890/lib/core_unwind_elfutils.c#L242 and then UID and GID of child is changed and then I can call elfutils: https://github.com/xsulca00/abrt/blob/iss%23890/src/hooks/abrt-hook-ccpp.c#L1361 https://github.com/xsulca00/satyr/blob/iss%23890/lib/core_unwind_elfutils.c#L392 Is there any way how I can pass the opened files to elfutils functions? Especially for "/etc/[tid]/mem" which is needed in dwfl_linux_proc_find_elf that is part of Dwfl_Callbacks proc_cb ?
