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.
We don't check the owner or permissions on a sudoers file that is
specified as an argument to visudo by default. However, the owner
and mode of files included via @includedir were still checked. This
commit makes the owner and permissions checks for filed included
via @includedir follow the same as for the original sudoers file.
The hook can be used to log parser errors (sudoers module) or keep
track of which files have an error (visudo).
Previously, we only kept track of a single parse error.
There is no case where we should fail to find an editor just because
the values of EDITOR, VISUAL and SUDO_EDITOR are unavailable. Both
sudoedit and the "env_editor" sudoers setting are documented as
falling back on the hard-coded list of editors in the "editors"
sudoers setting. Bug #1000
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.
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.
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.
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.
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.
