2166a6afe1 Remove use of setjmp/longjmp in the sudoers plugin. We no longer 
call fatal() except in the malloc wrappers and due to libsudo_util
there is now a single copy of fatal/fatalx.

87c2fe5a31 Prefix all libc replacements with sudo_ and #define the real name 
to the sudo_ version.  That way we don't pollute the libc namespace.

ffb07443c3 Do not allow the same callback function to be registered more that 
once in fatal_callback_register().
Add fatal_callback_deregister() to deregister a callback.

659b1f0e34 Switch to new time stamp file format. Each user now has a single 
file which may contain multiple records when per-tty time stamps
are in use (the default).  The time stamps use a monotonic timer
where available and are once again stored in /var/run/sudo.  The
lecture status is now stored separately from the time stamps in a
different directory.

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().
 2013-12-11 13:43:10 -07:00

8f9ce7249a Use strtonum() instead of atoi(), strtol() or strtoul() where possible. 2013-12-10 16:23:21 -07:00

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.

192cbbb490 Rename snprintf replacement rpl_snprintf since we may now replace 
the libc version and #define rpl_snprintf snprintf in missing.h so
we get our version when needed.  This is consistent with how we
replace glob and fnmatch.

3dab6bd8e9 Allow sudo to compile without variadic macro support in cpp. 
Debugging support will be limited (no file info from warnings.)

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().
 2013-11-18 08:59:57 -07:00

6c71ad5c15 Add debug_return_const_str and debug_return_const_ptr for returning 
a const string or pointer.  Using const for the normal versions
produces warnings with the Tru64 compiler.

237ae0b773 In v{warning,fatal}x?() make a new copy of ap for the debug functions. 
It is not legal to use ap twice without reinitializing it.
Noticed by Daniel Richard G.

adef363d00 Make a copy of readfds/writefds before calling select() instead 
of calculating it each time.  Keep track of high fd in the base.

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
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.
 2013-10-28 11:13:45 -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.

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
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.

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).
