[PATCH v2] Correct initial POSIX signals mask
Joel Sherrill
joel at rtems.org
Thu Sep 12 14:41:40 UTC 2019
+ Modify POSIX thread create extension to ensure expected
initial signal mask is provided to system threads, initial
tasks and threads, and inheritied by tasks and threads.
+ Adds psxsignal07 to verify functionality when using a POSIX
Initialization thread and POSIX threads.
+ Adds psxsignal08 to verify functionality when using a Classic API
Initialization task and Classic API tasks.
Closes #3794.
