449c4a290a Add sudo_ev_get_timeleft() to get the amount of time left before 
an event times out and use it in sudoreplay.

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

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.

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.

b2cba83688 Remove an errant list_next() call that should have been removed 
in the TAILQ conversion.

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.

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).

bec394dc11 Add support to the debug subsystem for zero-length strings. This 
can happen for things like warning(NULL) or fatal(NULL) where we
just want to log the errno string.

9b2fb418ca Don't allow max_groups to be set to zero, it just complicates things 
needlessly.  Fixes an assertion in visudo when there is a group-based
Defaults entry.

8b4fbc5cc0 Refactor code to parse list of gids into its own function that is 
shared by the sudo front-end and the sudoers module.
Make uid/gid parse error be fatal, not just a warning.

1f3ea50afd Implement memset_s() and use it instead of zero_bytes(). 
A new constant, SUDO_CONV_REPL_MAX, is defined by the plugin
API as the max conversation reply length.  This constant can be
used as a max value for memset_s() when clearing passwords
filled in by the conversation function.

95b50f84af Use time(&now) instead of now = time(NULL) when storing the current 
time in a time_t (better compiler error checking).
Better parsing and printing of 64-bit time_t on 32-bit platforms.

19d0946023 Simplify lbuf append functions by moving the realloc code into 
lbuf_expand().  We now expand as needed each time bytes need to be
written to the lbuf.  Also handle a NULL pointer being passed in
for paranoia's sake.

If the system free() can't handle free(NULL) this may crash but C89
was a long time ago.
