9b42640ef5 Change defaults callbacks to take a union sudo_defs_val * instead
of a char *.

05db5aa3b8 Remove sudo_mkpwcache() and sudo_mkgrcache(). We now create the
caches as needed on demand.  Also remove calls to sudo_freepwcache()
and sudo_freegrcache() that are immediately followed by execve(),
they are not needed.

23d288563e Eliminate use of setpwent()/endpwent() and setgrent()/endgrent().
Sudo never iterates over the passwd or group file.
Rename sudo_set{pw,gr}ent() -> sudo_mk{pw,gr}cache() and
use sudo_free{pw,gr}cache() instead of sudo_end{pw,gr}ent().

6717c32022 When determining whether or not "sudo -l" or "sudo -b" should prompt
for a password, take all sudoers sources into account.  In other
words, if both file and ldap sudoers sources are in use, "sudo -v"
will now require that all entries in both sources be have NOPASSWD
(file) or !authenticate (ldap) in the entries.

21d6fc3d8f Simple garbage collection (really a to-be-freed list) for the sudoers
plugin.  Almost identical to what sudo.c uses.  Currenly only the
environment strings are collected at exit time which is enough to
quiet address sanitizer's leak detector.

00142c91fa Lock individual records in the timestamp file instead of the entire
file.  This will make it possible for multiple sudo processes using
the same tty to serialize their timestamp lookups.

98a15d9879 Add a struct sudo_conv_callback that contains on_suspend and on_resume
function pointer args plus a closure pointer and at it to the
conversation function.

2751413464 display_privs() and display_cmnd() may need to return -1 on error. 2015-06-26 10:33:28 -06:00

d3bc17a611 Return -1, not 0 from sudoers when there is an error (as opposed to
a policy denial).

ac13264b44 Use a common function for resolviong the user's editor in sudoedit
and visudo.  The find_path() function now returns a dynamically
allocated path instead of using a static string.

allocation errors.

2bf454b74d Use non-exiting allocators in the redblack tree and fix the fallout.

04128f5985 Get rid of SUDO_MAIN. Modern compilers don't warn about mixing

be4872f691 For sudoedit, run the editor with the user's original environment

ee72cba937 Use futimens() and utimensat() instead of futimes() and utimes(). 2015-03-02 13:58:50 -07:00

5d2e9426b2 We cannot (easily) use clock_gettime(CLOCK_MONOTONIC) directly as
it may be present but not implemented.  Add sudo_gettime_real() and
sudo_gettime_mono() functions to get the real and monotonic times
respectively.  Now sudo_gettime_mono() checks the value of
sysconf(_SC_MONOTONIC_CLOCK) before calling clock_gettime(CLOCK_MONOTONIC)
and falls back on sudo_gettime_real() as needed.  The Mach version
of sudo_gettime_mono() uses mach_absolute_time().

This should fix problems with timestamp files on systems where
the CLOCK_MONOTONIC is defined but not actually implemented.

9d6e1a57d5 Add sudoers_debug_deregister() and use it instead of calling
sudo_debug_deregister() directly.

e9914a91b1 The sudoers plugin now defines its own list of debugging subsystem names
and defines.

866cfc4fc3 Add support for multiple Debug lines per program. Callers may
register arbitrary debug facilities or use built-in defaults.  We
now use separate Debug statements for plugins and programs.

a7e724b75d Change how sudo.conf is parsed. We now do a quick parse and then
set the values after the entire file has been parsed.  This lets
us init the debug system earlier.  Plugin-specific debug flags are
now stored in struct plugin_info and struct plugin_container and
passed to the plugin via one or more debug_flags settings.

bd99dcc028 Add sudo_warn_set_conversation() to specify a conversation function
to use for warn/fatal.  If no conversation function is specified,
the standard error will be used.  We now only need sudo_printf()
for things that use the parser.

15dee8745d Make sudoers file nsswitch functions static to parse.c since they

2a290f812e Return MODE_ERROR from sudoers_policy_deserialize_info() instead

2d1484fe84 Make a password/group cache collision a warning rather than fatal.
This should not be possible in practice and we can safely return
the new (potentially duplicate) item as it will be freed by the
caller.  Make sudo_set_grlist() return an error on failure instead
of calling fatalx().

639ac92e6d In find_path(), return NOT_FOUND_ERROR instead of calling fatal()
if the path is too long.  Remove an extraneous check against PATH_MAX
in set_cmnd() since find_path() already contains such a check.

12a1b672c0 We must include gettext.h before missing.h as it includes system

audit code that does not include sudoers.h.

7155fc526f Bring back boot time checking code and zero out time stamp files
that predate the boot time.  This should help systems w/o /var/run
where the admin has setup rc.d to clear the timestamp directory.
2014-02-03 05:45:27 -07:00
Todd C. Miller
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.
