plugin_error.c instead of the error.c from the front-end. This
means sudoers_setlocale() needs to be independent of the sudo_user
struct and the defaults table. The sudoers locale is now updated
via a callback.
present but empty) and the -u option was not specified, set runas_pw
to user_pw instead of using runas_default. This is intended to be
used in conjunction with the Solaris Privilege Set support for rules
that grant privileges without changing the user.
Move authentication failure logging to log_auth_failure().
Both of these call audit_failure() for us.
This subtly changes logging for commands that are denied by sudoers
but where the user failed to enter the correct password. Previously,
these would be logged as "N incorrect password attempts" but now
are logged as "command not allowed". Fixes bug #563
function so session setup can modify the user environment as needed.
For PAM authentication, merge the PAM environment with the user
environment at init_session time. We no longer need to swap in the
user_env for environ during session init, nor do we need to disable
the env hooks at init_session time.
hooks for getenv, putenv, setenv and unsetenv. This makes it
possible for the plugin to trap changes to the environment made by
authentication methods such as PAM or BSD auth so that such changes
are reflected in the environment passed back to sudo for execve().
LOGIN_SETENV instead of rolling our own login.conf setenv support
since FreeBSD's login.conf has more than just setenv capabilities.
This requires us to swap the plugin-provided envp for the global
environ before calling setusercontext() and then stash the resulting
environ pointer back into the command details, which is kind of a
hack.
The sudo front-end will now use getgrouplist() to get the user's
list of groups if getgroups() fails or returns zero groups so we
always have a list of the user's groups. For systems with
mbr_check_membership() which support more that NGROUPS_MAX groups
(Mac OS X), skip the call to getgroups() and use getgrouplist() so
we get all the groups.
group_info and use it to store both, along with a count for each.
Cache group info on a per-user basis using getgrouplist() to get
the groups. We no longer need special to special case the user or
list user for user_in_group() and thus no longer need to reset the
groups list when listing another user.
result of getgroups()) to names and store both the group names and
ids in the sudo_user struct. When matching groups in the sudoers
file, match based on the names in the groups list first and
only do a gid-based match when we absolutely have to. By matching
on the group name (as it is listed in sudoers) instead of id
(which we would have to resolve) we save a lot of group lookups
for sudoers files with a lot of groups in them.
