| Subject: signals: sys_ssetmask() uses uninitialized newmask |
| |
| From: Oleg Nesterov <oleg@redhat.com> |
| |
| 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. |
