8b009f62eb Plug memory leak in error path when sudoers cannot be opened. 2021-07-29 15:26:04 -06:00

2db9e64214 Move reference-counted string code from sudoers to libsudo_util.
It will be used by sudo_logsrvd too.

0663ffbc3f Use sudo_basename() instead of doing the equivalent manually. 2021-02-10 15:14:08 -07:00

3237a18ee3 Use sudoersrestart() in fuzz_sudoers.c
Since we run the parser multiple times we need to restart it each time.

6286ce1d16 Store column number for aliases, defaults and userspecs too.
This is used to provided the column number along with the line
number in error messages.  For aliases we store the column of the
alias name, not the value since that is what visudo generally needs.

1b300f78de Remove superfluous "parse error in sudoers near line N" message.
The sudoers parser now produces better syntax error messages so we
don't need visudo to print its own.

03eb3d6db9 Don't override errorfile and errorlineno set by check_aliases().
Now that alias parsing stores the file and line number, visudo can
use that information to go to the line with an error when re-editing.

cbad17a994 Move inclusion of compat headers up with the system headers.
Now that sudo_dso_public is defined in config.h we don't need sudo_compat.h
before including the compat headers.

7febc39137 In visudo check that an include file is regular file before using it.
Avoids a generic "input in flex scanner failed" error message.

446ae3f507 Include string.h unconditionally and only use strings.h for strn?casecmp()
In the pre-POSIX days BSD had strings.h, not string.h.
Now strings.h is only used for non-ANSI string functions.

dd88460800 We no longer need to include headers we don't use for sudo*.h files.
Previously we needed to include headers required by the various
sudo*h files.  Now those files are more self-sufficient and we
should only include headers needed by code in the various .c files.

635445d471 Transparently handle the "sudo sudoedit" problem.
Some admin are confused about how to give users sudoedit permission
and many users try to run sudoedit via sudo instead of directly.
If the user runs "sudo sudoedit" sudo will now treat it as plain
"sudoedit" after issuing a warning.  If the admin has specified a
fully-qualified path for sudoedit in sudoers, sudo will treat it
as just "sudoedit" and match accordingly.  In visudo (but not sudo),
a fully-qualified path for sudoedit is now treated as an error.

171686c422 update_defaults() needs to be able to take a defaults_list for

70d519c8ad o Move userspecs, defaults and aliases into a new struct sudoers_parse_tree.
o The parse tree is now passed to the alias, match and defaults functions.
o The nss API has been changed so that the nss parse() function returns
  a pointer to a struct sudoers_parse_tree which will be filled in
  by the getdefs() and query() functions.

f9be3a48a2 Simplify the nss interface such that each sudoers provider fills
in a per-nss list of userspecs and defaults instead of using separate
lookup and list functions.  This makes it possible to have a single
implementation of the code for sudoers lookup and listing.

3354cbd021 Add sudoers output format to cvtsudoers. In the future this may

98c19a68c9 Use the built-in sudoers file location as the default sudoers file
for cvtsudoers and move parse_sudoers_options() to stubs.c since
it is shared between visudo.c and cvtsudoers.c.

034132774d Call install_sudoers() even when doedit is false. If a file in a
#includedir has a syntax error it will still have been edited and
we need to install the edited temp file.
