Todd C. Miller
0ef5373678 Add canon_path(), a realpath() wrapper that performs caching. 
This also adds a new user_cmnd_dir variable that stores the
canonicalized parent directory of the command to be run.

78ff514358 match_command: apply runchroot if set when matching the command 
Previously we would prepend runchroot to the path we were checking
but that does not properly handle symbolic links.

13a311bc71 Add pivot_root() and unpivot_root() to switch the root dir and restore it. 
This will be used to more accurately handling command resolution and
path matching when a new root directory is specified.

a72bc5e6bf get_starttime: add support for GNU Hurd using the mach task_info call. 
This is currently Hurd-specific but could be made Mach-generic as
long as the equivalent of pid2task() is available.

0b000aab86 Only test get_starttime() on platforms where we support it. 
Fixes a test failure on systems where we have no way to determine
a process's start time.

It is possible to have mutiple matches from the output of "locale

26385b45cf Recover from missing include file unless error_recovery is disabled. 
It is still treated as an error from a logging perspective, and
mail is still sent.

1758c49d3e Get rid of sudoersdir and just use sysconfdir. 
There is no need for sudoersdir when it is always just set to sysconfdir.

3c9c8668c1 Avoid compilation errors if getaddrinfo() or freeaddrinfo() are macros. 
If this is the case we probably can't stub out the functions but
at least the fuzzer will compile.

334daf92b3 Escape control characters in log messages and "sudoreplay -l" output. 
The log message contains user-controlled strings that could include
things like terminal control characters.  Space characters in the
command path are now also escaped.

Command line arguments that contain spaces are surrounded with
single quotes and any literal single quote or backslash characters
are escaped with a backslash.  This makes it possible to distinguish
multiple command line arguments from a single argument that contains
spaces.

0274a4f3b4 sudoedit: do not permit editor arguments to include "--" (CVE-2023-22809) 
We use "--" to separate the editor and arguments from the files to edit.
If the editor arguments include "--", sudo can be tricked into allowing
the user to edit a file not permitted by the security policy.
Thanks to Matthieu Barjole and Victor Cutillas of Synacktiv

3878ce8d49 env_file_next_local: change the order of the val_len check. 
It makes more sense to verify that val_len > 1 before using it.
This is not a problem in practice because val[val_len - 1] is
guaranteed not to underflow but it can confuse reviewers and static
analyzers.

The sudo.conf file is considered a trusted source of information
