A new constant, SUDO_CONV_REPL_MAX, is defined by the plugin
API as the max conversation reply length. This constant can be
used as a max value for memset_s() when clearing passwords
filled in by the conversation function.
MAXHOSTNAMELEN and the MIN/MAX macros. We now use PATH_MAX and
HOST_NAME_MAX throughout without falling back on MAXPATHLEN or
MAXHOSTNAMELEN and define our own MIN/MAX macros as needed.
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.
to the target user immediately before setting resource limits, which
is after the monitor process has forked (so it has the old value).
Also, if the user did not authenticate, there is no pamh in the
monitor so we need to init pam here too. This means we end up
calling pam_start() twice, which should be fixed, but at least the
session is always properly closed now.
Set adminstrative domain for the process when looking up user's
password or group info and when preparing for execve().
Include strings.h even if string.h exists since they may define
different things. Fixes warnings on AIX and others.
before the uid/gid/etc changes. A struct passwd pointer is passed in,which may be NULL if the user does not exist in the passwd database.The sudoers module uses init_session to open the pam session as needed.
plugin itself. If possible, this should really be done in the main
driver but we don't presently have the needed data to do that. This
will be re-evaluated when Linux audit support is added.
