From 56893a61aa4f0270fa8d1197b9848247f90fce0d Mon Sep 17 00:00:00 2001

Subject: [PATCH] Fix invalid sigprocmask call
The POSIX document says
The pthread_sigmask() and sigprocmask() functions shall fail if:
[EINVAL]
The value of the how argument is not equal to one of the defined values.
and this is how musl-libc is currently doing. Fix the call to be safe
and correct
