From 5a88b8abb0a0f7b4611daaf5305c6cc08cdf5d2b Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Sat, 5 Jan 2013 19:13:13 +0100 Subject: [PATCH] signals: sys_ssetmask() uses uninitialized newmask commit 5ba53ff648e785445a32ba39112ed07e4cf588d0 upstream. Commit 77097ae503b1 ("most of set_current_blocked() callers want SIGKILL/SIGSTOP removed from set") removed the initialization of newmask by accident, causing ltp to complain like this: ssetmask01 1 TFAIL : sgetmask() failed: TEST_ERRNO=???(0): Success Restore the proper initialization.
