Summary

0000575: syslog() blocks when syslogd dies

Description

syslog() uses SIGPIPE to detect when the connection to syslogd is severed. However, when SIGPIPE is blocked, it blocks forever. syslog() should use non-blocking IO to ensure it's writes do not block.

Notes
(0008064) vda 06-03-08 07:04	Test program: #include <syslog.h> int main() { int i; for (i = 0; i < 10000; i++) syslog(LOG_INFO, "Testing, disregard...................."); return 0; } It indeed blocks if e.g. syslogd is stopped.
