Package: sredird Version: 2.2.1-1.1 To begin, I'm using sredird in a RedHat 8 system. uname -a --> Linux bfscs320.lsikc3.net 2.4.20-30.8.legacy.2 #1 Thu Jan 6 14:15:57 EST 2005 i486 i486 i386 GNU/Linux gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5)
I use xinetd to start sredird, the config file to start sredird is below.
I use a telnet client to connect to sredird (telnet abc.com 6001)
If I send a SIGTERM to sredird, it does not exit. The files are all closed and
the lock released, but both sredird and the telnet client remain running.
A SIGKILL to sredird will end sredird and the telnet client exits. (That's
what I expect to happen with a SIGKILL)
I believe the problem is in the function SignalFunction. It calls ExitFunction,
which
does all the cleanup, but then returns to SignalFunction, which then returns to
the
interrupted code.
I replaced the call to ExitFunction with a call to exit(0), and sredird now
exits if it gets a
SIGTERM.
I did the same to BreakFunction, but I have not tested that change yet.
I hope this helps.
================================================
/* Function called on many signals */
void SignalFunction(int unused)
{
/* Just to avoid compilation warnings */
/* There's no performance penalty in doing this
because this function is almost never called */
unused = unused;
/* Same as the exit function */
/*ExitFunction(); replace with a call to exit */
exit (0);
}
