Linux hang on attach #4

Closed tel0seh closed 10 years ago

tel0seh commented 10 years ago

uname -a : Linux Relentless 3.12-1-amd64 #1 SMP Debian 3.12.9-1 (2014-02-01) x86_64 GNU/Linux

the attach blocks on a futex() syscall, the end of an strace output is available here:

behaviour occurs using both frida-trace and python bindings.

Using Debian and a newer kernel, the attachment fails, but for me it makes the target application crash.

The sysctl option was set according to Frida documentation.

Linux _____ 3.13-1-amd64 #1 SMP Debian 3.13.10-1 (2014-04-15) x86_64 GNU/Linux

Frida output: $ frida-trace xeyes Failed to attach: remote_call PTRACE_CONT wait failed: 0

Target application crashes with: $ xeyes Illegal instruction

@guillaume-uH57J9 Excellent. I will try to reproduce in a VM and let you know how it goes.

Thanks!

@guillaume-uH57J9 To clarify, this is a 64-bit system, right?
