a78da37487 Make set_perms() and restore_perms() return an error instead of

6a295400b7 Make "internal error, %s overflow" arguments consistent, using
__func__ where possible (when debugging is allowed).

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.

2220f55aef Propagate errors in audit code to caller instead of using fatal().
If we fail to audit an otherwise successful command, return an error
from the policy.  For Linux audit, sudo may be compiled with audit
support but auditing may not be setup, so we don't consider that
an error.

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().

0817429583 More sign compare fixes. On Solaris id_t is signed so use uid_t
in the set_perms.c ID macro instead.

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.

c376c71618 Move the -C (user_closefrom) check until after set_cmnd() so that
closefrom_override can be used in a command-specific Defaults line.

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.

41ab8da22c Fall back to opening /dev/tty to determine whether there is a tty
if the system doesn't have kernel support for determing the tty.

37b4b5d15e Now that we can determine the terminal even when file descriptors
are redirected we can check user_ttypath rather than opening
/dev/tty when enforcing requiretty.

Todd C. Miller
99704cc101 Catch SIGINT, SIGQUIT and SIGTSTP in the front end before we execute
the command.  If we get SIGINT or SIGQUIT, call the plugin close()
functions as if the command was interrupted.  If we get SIGTSTP,
uninstall the handler and deliver SIGTSTP to ourselves.

9479bb623b Add exec_background option in plugin command info and a sudoers
option to match.  When set, commands are started in the background
and automatically foregrounded as needed.  There are issues with
some ill-mannered programs (like Linux su) so this is not the
default.

1d7072fe09 Don't include <sys/param.h>. We only needed it for MAXPATHLEN,
MAXHOSTNAMELEN and the MIN/MAX macros.  We now use PATH_MAX and
HOST_NAME_MAX throughout without falling back on MAXPATHLEN or
MAXHOSTNAMELEN and define our own MIN/MAX macros as needed.

2632ec7e69 Move warn/error into common and make static builds work. 2012-11-25 09:34:40 -05:00

c2c6616a0c Move _sudo_printf from src/conversation.c to common/sudo_printf.c.
Add sudo_printf function pointer that is initialized to _sudo_printf()
instead of requiring a sudo_conv function pointer everywhere.  The
plugin will reset sudo_printf to point to the version passed in via
the plugin open function.  Now plugin_error.c can just call sudo_printf
in all cases.  The sudoers binaries no longer need their own version
of sudo_printf.

5496ffe1e8 Add plugin_setjmp() wrapper for siglongjmp(error_jmp, 1) so we don't
need error_jmp to be extern.  Also add plugin_clearjmp() that clears
a flag so error()/errorx() knows when to call exit() vs. longjmp().

7b3d268687 Call gettext() on parameters for warning()/warningx() instead of

90147bb605 Allow sudoers programs (visudo, sudoreplay, visudo) to use
plugin_error.c instead of the error.c from the front-end.  This
means sudoers_setlocale() needs to be independent of the sudo_user
struct and the defaults table.  The sudoers locale is now updated
via a callback.
