2012-02-15tevent_signal: Fix a valgrind errorVolker Lendecke1-1/+2
This fixes an uninitialized read introduced by my fix for the tevent_signal destructors. From looking at the code you might believe that this kicks in only when talloc failed. But with -O3 I do see it in normal operations. Sorry for that. Autobuild-User: Volker Lendecke <vl@samba.org> Autobuild-Date: Wed Feb 15 17:58:37 CET 2012 on sn-devel-104

2011-11-10Fix -Wunused-but-set-variable compiler warnings in tevent_signal.cMartin Schwenke1-4/+2
The results of some read(2) and write(2) calls are assigned into a variable that is never used. Presumably this used to avoid compiler warnings or similar. However, from (approximately) GCC 4.6 this produces some warnings: [ 609/3910] Compiling lib/tevent/tevent_signal.c ../lib/tevent/tevent_signal.c: In function ‘tevent_common_signal_handler’: ../lib/tevent/tevent_signal.c:85:10: warning: variable ‘res’ set but not used [-Wunused-but-set-variable] ../lib/tevent/tevent_signal.c: In function ‘signal_pipe_handler’: ../lib/tevent/tevent_signal.c:183:10: warning: variable ‘res’ set but not used [-Wunused-but-set-variable] The simplest thing to do is remove the variables and cast the function return to void.

2009-09-22lib/tevent: a cleaner fix for be4ac227842530d484659f2db683453366326d8b segvRusty Russell1-7/+1
Revert 23abcd2318c69753aa2a144e1dc0f9cf9efdb705 and fix logic bug. The current code loops through the event contexts, when it sees a different one, it notifies the current one (ev) and updates ev to point to the new one. This is dumb, because: (1) ev starts as NULL, so this code crashes, and (2) The final context will not be notified. The correct fix for this is to update ev to the new one, then notify it. Volker's fix works because we currently always have one event context. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2009-09-03Another part of the fix for bug 6651 - smbd SIGSEGV when breaking oplocks.Jeremy Allison1-2/+6
SA_INFO_QUEUE_COUNT *MUST* be a power of 2, in order for the ring buffer wrap to work correctly at the 32 bit boundary. Thanks to Petr Vandrovec <petr@vandrovec.name> for this.
2009-08-29tevent: Fix a segfault upon the first signalVolker Lendecke1-0/+6
When the first signal arrives, tevent_common_signal_handler() crashed: "ev" is initialized to NULL, so the first "write(ev->pipe_fds[1], &c, 1);" dereferences NULL. Rusty, Tridge, please check. Also, can you tell me a bit more about the environment you tested this in? I'd be curious to see where this survived. Thanks, Volker
2009-08-28lib/tevent: handle tevent_common_add_signal on different event contexts.Rusty Russell1-14/+30
I don't know if this is a problem in real life. The code assumes there's only one tevent_context; all signals will notify the first event context. That's counter-intuitive if you ever use more than one, and there's nothing else in this code which prevents it AFAICT. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-08-28lib/tevent: fix race with signals and tevent_common_add_signalRusty Russell1-20/+20
We carefully preserve the old signal handler, but we replace it before we've set up everything; in particular, if we fail setting up the pipe_hack we could write a NUL char to stdout (fd 0), instead of calling the old signal handler. Replace the signal handler as the very last thing we do. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-08-28lib/tevent: remove spectacularly complicated manual subtractionRusty Russell1-4/+1
To be completely honest, I don't quite know whether to laugh or cry at this one: 1 + (0xFFFFFFFF & ~(s.seen - s.count)) == 1 + (~(s.seen - s.count)) # s.seen, s.count are uint32_t == s.count - s.seen # -A == ~A + 1 Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
