[pulseaudio-discuss] [PATCH 0/2] fix pulseaudio for sandbox

[Julien Isorce]

- Problem:
One of the sandbox layer can be Seccomp-BPF.
When a process is in this mode, it currently
cannot use pulseaudio.

- Cause:
During startup, pulseaudio will crash the first time
it calls open from the thread that runs its main loop.
In thread-mainloop.c::thread, it blocks all signals.
But SIGSYS is actually the signal used by Seccomp-BPF.
So it has to be unblocked.
Otherwise pulseaudio crashes on the open.
(It is actually killed by the kernel)

Julien Isorce (2):
  pa_make_secure_dir: avoid calling fchmod if already right mode
  thread-mainloop: unblock SIGSYS on sandbox
