From d6e5f3ad1fdb7964d843c86f86d4ee7d806a0f93 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Wed, 17 Jun 2015 14:31:49 +0200 Subject: core: execute: fix regression in pam_setup() Commit 72c0a2c25 ("everywhere: port everything to sigprocmask_many() and friends") reworked code tree-wide to use the new sigprocmask_many() helper. In this, it caused a regression in pam_setup, because it dropped a line to initialize the 'ss' signal mask which is later used in sigwait(). While at it, move the variable declaration to an inner scope. --- src/core/execute.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/src/core/execute.c b/src/core/execute.c index 444865da86..a6ff5ac56e 100644 --- a/src/core/execute.c +++ b/src/core/execute.c @@ -771,7 +771,7 @@ static int setup_pam( }; pam_handle_t *handle = NULL; - sigset_t ss, old_ss; + sigset_t old_ss; int pam_code = PAM_SUCCESS; int err; char **e = NULL; @@ -868,6 +868,11 @@ static int setup_pam( /* Check if our parent process might already have * died? */ if (getppid() == parent_pid) { + sigset_t ss; + + assert_se(sigemptyset(&ss) >= 0); + assert_se(sigaddset(&ss, SIGTERM) >= 0); + for (;;) { if (sigwait(&ss, &sig) < 0) { if (errno == EINTR) -- cgit v1.2.3-54-g00ecf
