ec751c63eb log_allowed: pass struct eventlog * instead of argv[] and envp[].
This lets us log based on the command_info[] list passed in from
the front-end.  Previously, much of the struct eventlog was constructed
from internal sudoers state instead.

dae370fb70 Use a separate uuid for intercepted commands.
We use the uuid to match the command with its exit status.

1ae9954c63 Use run_argv and run_envp passed into the audit plugin for event logging.
Previously we used NewArgv[] and env_get() but now that logging is
performed via an audit plugin we should use the values passed in.

17a415ae77 Add log_exit_status sudoers option to log when a command exits.
This option defaults to off.

95fb8eb727 Add sudoerserrorf(), a printf-style yyerror() function.
Use this to display a better error message when using a reserved
work in an alias definition.

56fb16d3e8 Use sudoers_to_eventlog() and init_log_details() in sudoers_audit_accept().
log_deserialize_info() can be private to iolog.c again.

d899fe5936 Use real setters for the eventlog config.
This makes it possible to have a base config that the callers can
modify instead of replacing the config wholesale.

bd1ca79cca Add support for mailing eventlog entries and for logging raw messages.
These will be used by the sudoers plugin.

f1d19f1d6e Add SLOG_AUDIT flag for log_warningx() to also audit the message.
This lets us combine audit_failure() and log_warningx() calls with
the same message.

f047377a07 Add basic support for reject and error audit events to sudoers.
This is only used when logging events from plugins other than sudoers,
such as an approval plugin.  With this change, if an approval
plugin rejects the command the denial will be logged in the
sudoers log file using the message from the approval plugin.

b519481912 Defer logging of the successful command until approval plugins have run.
This adds audit plugin support to the sudoers module, currently
only used for accept events.  As a result, the sudoers file is now
initially parsed as an audit plugin.

45e589d443 Pass back a failure or error string to the front end.
The audit_failure() function now stores the failure string.
This will allow an audit plugin to log the reason if the user's
request is a rejected.

9d1c408b73 Non-exiting allocators for log functions. If log_allowed() fails
the user may not run the command.  We don't try to return early for
log_failure(), log_auth_failure() or log_denial() as we would not
run the command in that case.

8bc70a635c Instead of trying to make weak functions work on all platforms,
just use a registration function for a plugin-specific setlocale
function.  The sudoers version just wraps sudoers_setlocale().

2220f55aef Propagate errors in audit code to caller instead of using fatal().
If we fail to audit an otherwise successful command, return an error
from the policy.  For Linux audit, sudo may be compiled with audit
support but auditing may not be setup, so we don't consider that
an error.

90147bb605 Allow sudoers programs (visudo, sudoreplay, visudo) to use
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.

a0c53bd751 Call gettext inside log_error et al instead of having the caller do it. This way we can display any messages to the user in their own locale but log in the sudoers local. 2012-11-08 15:37:44 -05:00

4207589fe2 Add simple locale switching to make it easy to switch from the

5d052aeb60 Do not inform the user that the command was not permitted by the
policy if they do not successfully authenticate.  This is a regression
introduced in sudo 1.8.6.

8b03f3e7d0 Move log_denial() calls and logic to log_failure().
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

44ce5720de Remove the NO_EXIT flag to log_error() and add a log_fatal() function
that exits and is marked no_return.  Fixes false positives from
static analyzers and is easier for humans to read too.
