"ptrace(PTRACE_GETSIGINFO) failed" issue #10

Open x1m0 opened 7 years ago

x1m0 commented 7 years ago

Hi,

On a 64 linux box with SElinux disabled, and no Yama protection, I'm getting on most of the processes (not all) the following error:

./inject -p 12345 test-lib.so

targeting process with pid 12345 ptrace(PTRACE_GETSIGINFO) failed

Any ideas why this is happening?

Thanks in advance!
