cbf41b8b96 The OpenBSD strtonum() uses very short error strings that can't 
be translated usefully.  Convert them to longer strings on error.
Also use the longer strings for atomode() and atoid().

0d81263e26 Instead of setprogname(), add initprogname() which gets the program 
name for getprogname() using /proc or pstat() if possible.

12f3bdf60e Add wrapper functions for dlopen() et al so that we can support 
statically compiling in the sudoers plugin but still allow other
plugins to be loaded.  The new --enable-static-sudoers configure
option will cause the sudoers plugin to be compiled statically into
the sudo binary.  This does not prevent other plugins from being
loaded as per sudo.conf.

96eb2c4f8f Add warning_gettext() wrapper function that changes to the user locale, 
then calls gettext().
Add U_ macro that calls warning_gettext() instead of gettext().
Rename warning2()/error2() back to warning_nodebug()/error_nodebug().

87e1ae76af Uniquify header dependencies so we don't end up with duplicates 
when a header file includes other headers.  The header dependencies
are sorted so the generated order is stable.

b616a0431f Extra debugging for ready fds. 2013-11-04 06:06:38 -07:00
Todd C. Miller
60d58f3a64 When deleting an event, check ev->events to determine whether to 
remove from readfds or writefds instead of blinding removing from
both.  Also fix highfd adjustment.
 2013-11-04 06:06:01 -07:00
Todd C. Miller
0eb38a228a Only check an fd that is >= 0. Timeout-only events may have a 
negative fd.
 2013-11-02 10:13:54 -06:00
Todd C. Miller
1a548a5dda Don't call sudo_ev_{add,del}_impl() for timeout-only events. This 
makes it possible to pass sudo_ev_alloc() an fd of -1 for events
only use SUDO_EV_TIMEOUT.
 2013-11-01 16:54:49 -06:00
Todd C. Miller
adef363d00 Make a copy of readfds/writefds before calling select() instead 
of calculating it each time.  Keep track of high fd in the base.
 2013-10-31 16:13:15 -06:00

449c4a290a Add sudo_ev_get_timeleft() to get the amount of time left before 
an event times out and use it in sudoreplay.
 2013-10-29 08:16:42 -06:00
Todd C. Miller
1bc2901a26 Fix sudo_ev_scan_impl() return value in event_poll.c. 
Make sure we clear active flag from unprocessed events if
sudo_ev_loopbreak() or sudo_ev_loopcontinue() are used.
Remove bogus optimization when the timeout is zero or negative; it
could prevent an I/O event from being triggered.

4d1f912746 Get rid of cur and pending pointers in struct sudo_event_base. We 
now pop the first event off the active queue instead of using a
foreach loop with deferred removal of the event.
Add SUDO_EVQ_INSERTED and SUDO_EVQ_TIMEOUTS flags to indicate that
the event on the event queue and timeouts queue respectively.
No longer need to compare the timeout to {0,0} or compare the
event's base pointer to NULL to determine queue membership.

4413f89bd3 rename sudo_ev_loop_impl() -> sudo_ev_scan_impl() 2013-10-28 10:10:22 -06:00
Todd C. Miller
8861e01d16 Add support for libevent-style timed events. Adding a timed event 
is currently O(n).  The only consumer of timed events is sudoreplay
which only used a singled one so O(n) == O(1) for now.  This also
allows us to remove the nanosleep compat function as we now use a
timeout event instead.
 2013-10-28 10:00:09 -06:00
Todd C. Miller
e16c99cd2a Add a list of active events in the base that the back end sets when 
it calls poll or select.  This allows the front end to iterate over
the events instead of having that code in both back ends.  It will
also simplify support for timeout events.  Also make sure we can't
touch freed memory if a callback frees its own event.
 2013-10-26 06:55:23 -06:00

b2cba83688 Remove an errant list_next() call that should have been removed 
in the TAILQ conversion.
 2013-10-22 09:33:12 -06:00
Todd C. Miller
b38d253e98 Add "headless" tail queues and use them in place of the semi-circular 
lists in sudoers.  Once the headless tail queue is built up it is
converted to a normal TAILQ.  This removes the last consumer of
list.c and list.h so those can now be removed.
 2013-10-22 09:08:38 -06:00
Todd C. Miller
f85106ea67 Use SLIST and STAILQ macros instead of doing headless singly linked 
lists manually.  As a bonus we now use a tail queue for ldap.c and
sudoreplay.c.
 2013-10-22 09:08:09 -06:00
Todd C. Miller
923edabe6c Convert sudo to use BSD TAILQ macros instead of home ground tail 
queue functions.  This includes a private queue.h header derived
from FreeBSD.  It is simpler to just use our own header rather than
try to deal with macros that may or may not be present in various
queue.h incarnations.

69ab48f16d Don't allow the debug subsystem to be initialized twice. 
Otherwise we can exhuast our stack when built in static mode.

6a5d6f9e9e Make sure we do not try to usie index -1 in base->pfds[]. 2013-10-16 16:08:54 -06:00

79acd5db49 Simple event subsystem that uses poll() or select(). Basically a 
simplied subset of libevent2.  Currently only fd events are supported
(since that's all we need).  The poll() backend is used by default,
except on Mac OS X where poll() is broken for devices (including
/dev/tty and ptys).
