* Fixed a bug introduced in version 1.8.21 which prevented sudo
from using the PAM-supplied prompt. Bug 799
* Fixed a bug introduced in version 1.8.21 which could result in
sudo hanging when running commands that exit quickly. Bug 800
* Fixed a bug introduced in version 1.8.21 which prevented the
command from being run when the password was read via an external
program using the askpass interface. Bug 801
What's new in Sudo 1.8.21p1
* On systems that support both PAM and SIGINFO, the main sudo
process will no longer forward SIGINFO to the command if the
signal was generated from the keyboard. The command will have
already received SIGINFO since it is part of the same process
group so there's no need for sudo to forward it. This is
consistent with the handling of SIGINT, SIGQUIT and SIGTSTP.
Bug 796
* If SUDOERS_SEARCH_FILTER in ldap.conf does not specify a value,
the LDAP search expression used when looking up netgroups and
non-Unix groups had a syntax error if a group plugin was not
specified.
* "sudo -U otheruser -l" will now have an exit value of 0 even
if "otheruser" has no sudo privileges. The exit value when a
user attempts to lists their own privileges or when a command
is specified is unchanged.
* Fixed a regression introduced in sudo 1.8.21 where sudoreplay
playback would hang for I/O logs that contain terminal input.
* Sudo 1.8.18 contained an incomplete fix for the matching of
entries in the LDAP and SSSD backends when a sudoRunAsGroup is
specified but no sudoRunAsUser is present in the sudoRole.
What's new in Sudo 1.8.21
* The path that sudo uses to search for terminal devices can now
be configured via the new "devsearch" Path setting in sudo.conf.
* It is now possible to preserve bash shell functions in the
environment when the "env_reset" sudoers setting is disabled by
removing the "*=()*" pattern from the env_delete list.
* A change made in sudo 1.8.15 inadvertantly caused sudoedit to
send itself SIGHUP instead of exiting when the editor returns
an error or the file was not modified.
* Sudoedit now uses an exit code of zero if the file was not
actually modified. Previously, sudoedit treated a lack of
modifications as an error.
* When running a command in a pseudo-tty (pty), sudo now copies a
subset of the terminal flags to the new pty. Previously, all
flags were copied, even those not appropriate for a pty.
* Fixed a problem with debug logging in the sudoers I/O logging
plugin.
* Window size change events are now logged to the policy plugin.
On xterm and compatible terminals, sudoreplay is now capable of
resizing the terminal to match the size of the terminal the
command was run on. The new -R option can be used to disable
terminal resizing.
* Fixed a bug in visudo where a newly added file was not checked
for syntax errors. Bug 791.
* Fixed a bug in visudo where if a syntax error in an include
directory (like /etc/sudoers.d) was detected, the edited version
was left as a temporary file instead of being installed.
* On PAM systems, sudo will now treat "username's Password:" as
a standard password prompt. As a result, the SUDO_PROMPT
environment variable will now override "username's Password:"
as well as the more common "Password:". Previously, the
"passprompt_override" Defaults setting would need to be set for
SUDO_PROMPT to override a prompt of "username's Password:".
* A new "syslog_pid" sudoers setting has been added to include
sudo's process ID along with the process name when logging via
syslog. Bug 792.
* Fixed a bug introduced in sudo 1.8.18 where a command would
not be terminated when the I/O logging plugin returned an error
to the sudo front-end.
* A new "timestamp_type" sudoers setting has been added that replaces
the "tty_tickets" option. In addition to tty and global time stamp
records, it is now possible to use the parent process ID to restrict
the time stamp to commands run by the same process, usually the shell.
Bug 793.
* The --preserve-env command line option has been extended to accept
a comma-separated list of environment variables to preserve.
Bug 279.
* Friulian translation for sudo from translationproject.org.
