b14d633ec6 Add runas_check_shell flag to require a runas user to have a valid shell. 
Not enabled by default.

df8f06609c Add a new flag "allow_unknown_runas_id" to control matching of unknown IDs. 
Previous, sudo would always allow unknown user or group IDs if the
sudoers entry permitted it.  This included the "ALL" alias.
With this change, the admin must explicitly enable support for unknown IDs.

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.

6260bf60b4 sudoedit doesn't create a new PAM session so PAM umask does not apply. 2019-10-18 06:43:33 -06:00
Todd C. Miller
b02851dcf3 Change how the umask is handled with PAM and login.conf. 
If the umask is explicitly set in sudoers, use that value regardless
of what is in PAM or login.conf.  If using the default umask from
sudoers, allow PAM or login.conf to override it.  Bug #900

8761217f83 Be more consistent with how we talk about sudoers Defaults settings. 
Use "flag" not "option" when referring to boolean flags.
Use "setting" in place of "Defaults setting" in most places.
Use "the foo option" instead of "sudo's foo option" for command line options.

3e56be3564 Store signal name, not number in I/O log timing file. 
The "SIG" prefix is not used so, e.g. SIGTERM -> "TERM".
This makes the I/O log files portable from one system to another.
Older I/O log files with signal numbers can still be replayed.

81602ad086 sudoedit should be used for editing files instead of "sudo editor"

958cf7e37f Don't describe env_editor as a security hole. 
Users that are able to edit sudoers can grant themselves permissions
so the fact that visudo runs the editor as root is not a security issue.

6fe2223298 Fix details of how EDITOR, VISUAL and SUDO_EDITOR are (or are not) preserved.

e010706ede Use roff conditionals in the manuals instead of post-processing. 
We still need to process the resulting .man.in files to add back
the conditionals but this should be easier to debug as the changes
are visible in the .in file.
Some minor postprocessing is still used to make the manuals HP-UX
friendly and to change "0 seconds" -> unlimited after substitution.

7c0019d2a5 Revert changes to give arguments to the .Bx macro. 
This is intended for things like .Bx 4.3 to generate "4.3BSD" so
the argument ends up before the BSD, not after.  Just go back to
using "BSD authentication" and "BSD login classes" so fixmdoc.sh
can operate correctly.  Bug #861

5f61f2c0f4 Remove special handling of the USERNAME environment variable. It 
used to be set on old versions of Fedora but that hasn't been the
case for some time.  It's worth noting that ssh doesn't set USERNAME
either.

0484e3d6a9 Fix ambiguity when talking about Aliases. We can't use User_Alias 
in the grammar as both the definition of the Alias as well as its
name.  This adds {User,Runas,Host,Cmnd}_Alias_Spec to help differentiate
between the name of the alias and its definition.  Bug #834
