[sudo-workers] sudo 1.8.22b2 released

[Todd C. Miller]

The second beta version of sudo 1.8.22 is now available.  Sudo
1.8.22 is primarily a bug fix release.  It fixes several long-standing
issues with job control when I/O logging is enabled as well as
fixing a potential time stamp file re-use problem.

The sudo distribution files are now signed with a new pgp key.
The PGPKEYS file has been updated accordingly.

Major changes between sudo 1.8.22b2 and 1.8.22b1:

 * A new "authfail_message" sudoers option that overrides the
   default "N incorrect password attempt(s)".

 * An empty sudoRunAsUser attribute in the LDAP and SSSD backends
   will now match the invoking user.  This is more consistent with
   how an empty runas user in the sudoers file is treated.

 * Documented that in check mode, visudo does not check the owner/mode
   on files specified with the -f flag.  Bug #809.

 * It is now an error to specify the runas user as an empty string
   on the command line.  Previously, an empty runas user was treated
   the same as an unspecified runas user.  Bug #817.

 * When "timestamp_type" option is set to "tty" and a terminal is
   present, the time stamp record will now include the start time
   of the session leader.  When the "timestamp_type" option is set
   to "ppid" or when no terminal is available, the start time of
   the parent process is used instead.  This significantly reduces
   the likelihood of a time stamp record being re-used when a user
   logs out and back in again.  Bug #818.

Major changes between sudo 1.8.22b1 and 1.8.21p2:

 * Commands run in the background from a script run via sudo will
   no longer receive SIGHUP when the parent exits and I/O logging
   is enabled.  Bug #502

 * A particularly offensive insult is now disabled by default.
   Bug #804

 * The description of "sudo -i" now correctly documents that
   the "env_keep" and "env_check" sudoers options are applied to
   the environment.  Bug #806

 * Fixed a crash when the system's host name is not set.
   Bug #807

 * The sudoers2ldif script now handles #include and #includedir
   directives.

 * Fixed a bug where sudo would silently exit when the command was
   not allowed by sudoers and the "passwd_tries" sudoers option
   was set to a value less than one.

 * Fixed a bug with the "listpw" and "verifypw" sudoers options and
   multiple sudoers sources.  If the option is set to "all", a
   password should be required unless none of a user's sudoers
   entries from any source require authentication.

 * Fixed a bug with the "listpw" and "verifypw" sudoers options in
   the LDAP and SSSD back-ends.  If the option is set to "any", and
   the entry contained multiple rules, only the first matching rule
   was checked.  If an entry contained more than one matching rule
   and the first rule required authentication but a subsequent rule
   did not, sudo would prompt for a password when it should not have.

 * When running a command as the invoking user (not root), sudo
   would execute the command with the same group vector it was
   started with.  Sudo now executes the command with a new group
   vector based on the group database which is consistent with
   how su(1) operates.

 * Fixed a double free in the SSSD back-end that could occur when
   ipa_hostname is present in sssd.conf and is set to an unqualified
   host name.

 * When I/O logging is enabled, sudo will now write to the terminal
   even when it is a background process.  Previously, sudo would
   only write to the tty when it was the foreground process when
   I/O logging was enabled.  If the TOSTOP terminal flag is set,
   sudo will suspend the command (and then itself) with the SIGTTOU
   signal.
