60eef27e6d Add verbose version of "sudo -l command" by using an extra -l.
The output of "sudo -ll command" consists of the matching sudoers
rule (in long form) with the addition of a "Matched" entry that
shows the fully-qualfied path along with any arguments.

f6a9bb2e23 Use a single callback for sudoers_lookup() and add a closure pointer.
The single callback now receives all the match info (or UNSPEC if
no match was attempted).  This makes it possible to use the callback
for more than just printing testsudoers output.

75256516bd testsudoers: add -L, -l and -v options.
This makes it possible to test "sudo -l" and "sudo -v" using
testsudoers.

5d758264ab Give every printf-like function restrict qualifiers
The format value has to be a string literal, every time.

Otherwise, you are not using these functions correctly. To reinforce this fact, I putrestrict over every non-contrib example of this I could find.

260c2fb835 testsudoers: display "Parse error" if there was a parse error.
Previously, we just printed "Command unmatched" which makes it
harder to see that an error occurred.

6a21aec0a6 testsudoers: use allowed/denied/unmatched instead of just matched/unmatched
This makes it possible to tell whether an entry was rejected due
to a negative match (explicitly denied) as opposed to a non-match.
Also fixes a bug where the runas status was only printed for positive
matches.

bde363e060 Rename parser_conf -> sudoers_conf in all but the parser itself. 2023-05-09 07:29:06 -06:00
Todd C. Miller
8cbd5462a6 Move sudoers search path to struct sudoers_parser_config.
That way we can avoid passing it to init_parser() directly.
We still need sudoers_search_path to be shared between the lexer
and the parser.

9d7c30c5a8 Add struct sudoers_parser_config and pass it to init_parser().
This struct contains parser configuration such as the sudoers file
uid/gid/mode and parse flags such as verbose, strict and recovery.

bbbaea5b2f Rename init_parser_ext() to init_parser() and remove old wrapper.
There was only one consumer of the init_parser() wrapper now that
reset_parser() has been introduced.

the user_cmnd variable could be freed twice.

e707ffe58b Place C23 attributes before keywords in function declarations.
In practice this means we must use "sudo_noreturn static foo(void)"
instead of "static sudo_noreturn foo(void)".

3940020c94 sudo_secure_open_{file,dir}: always check thatreturn value is not -1.
Avoids false positives from static analyzers that can't figure out
that the fd is always valid when error is SUDO_PATH_SECURE.

88ac5e09b6 Use sudo_secure_open_file() instead of sudo_secure_file() where possible.
Both sudo_secure_open_file() and sudo_secure_open_dir() are now passed
a struct stat pointer like sudo_secure_file() and sudo_secure_dir().

304726a215 Move gcc-style __attribute__ macros to config.h.in
Renamed __malloc -> sudo_malloclike, __printflike -> sudo_printflike,
__printf0like -> sudo_printf0like.
Add sudo_noreturn instead of __attribute__((__noreturn__)).
We do not use stdnoreturn.h since it has been deprecated in C23
in favor of the [[noreturn]] attribute.

bb5843055e Replace messages like "unknown foo: %s" with "unknown foo %s".
The colon really doesn't belong there; we generally use a colon to
separate a message from the warning detail.

322e0b3693 Return NOT_FOUND from the set_cmnd_path() stub since we don't set user_cmnd.
The purpose of set_cmnd_path() is to reset user_cmnd based on a new
runchroot.  For the stub version we don't modify user_cmnd and so
must not return a status of FOUND.
Fixes oss-fuzz issue #31250 which only affected the fuzzer and not sudo.

b6dbfe5094 Take the chroot into account when search for the command.
This could a a user-specific chroot via the -R option, a runchroot
Defaults value, or a per-command CHROOT spec in the sudoers rule.
