- 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 src/pulse/thread-mainloop.c | 10 ++++++++++ src/pulsecore/core-util.c | 2 +- 2 files changed, 11 insertions(+), 1 deletion(-) -- 1.9.1
