c4a579cf8a Pass resource limits values to the plugin in user_info[]
Sudo resets the resource limits early in its execution so
the plugin cannot tell what the original limits were itself.

cef6e3687e Switch from memset_s() -> explicit_bzero().
memset_s() (and all of Annex K) is likely to be removed from the
a future version of the standard.

48c2bd0007 Declare getdelim(3) if it exists in libc but is not prototyped in stdio.h.
This can happen on systems with a gcc packages that was built on
and older versions of the OS where getdelim(3) was not present.

f0dc48548c Add support for "accept" audit events sent by the sudo front-end.
With this change, the sudo front-end will send an "accept" audit
event to the audit plugins after all the I/O logging plugins have
been initialized.  This can be used by an audit plugin that does
not care about the result of the individual policy and approval
plugins and only wants to receive a single "accept" event if all
policy and approval plugins have succeeded.  The plugin_type argument
for events sent by the front-end is SUDO_FRONT_END (0).

d85d370c63 Add dependent system includes to make sudo_*.h more standalone.
In the past we've relied on the various .c files to include the
system headers that define types that the sudo_*.h headers require.
This is fragile and can cause issues when includes get re-ordered.

6901fc97ac Add a ClientHello message that client sends to the server.
This makes it easier to detect a plaintext client sending to a
TLS port.  Without this, the TLS server will be silent as it
waits for the client to initiate the TLS connection.
2020-05-05 13:23:26 -06:00

e5f8214c0a Remove the tls parameter from the ServerHello message.
The TLS connection is now initiated before ServerHello is received.

b5a317aeb9 Add support for a tls flag in sudo_parse_host_port().
If the string "(tls)" appears at the end, the tls flag is set to true
and the default tls port is used if necessary.

01a53f2865 Add open and close functions to the approval plugin API.
We need a close function to be able to to free memory allocated for
errstr.  Unlike the other plugins, the close function is called
immediately after the plugin's check or show_version function.
The plugin does not remain open until the command completes.

db17cadaf6 Add an approval plugin type that runs after the policy plugin.
The basic idea is that the approval plugin adds an additional
layer of policy.  There can be multiple approval plugins.

22105009d8 Define a new plugin type that receives accept and reject messages.
This can be used to implement logging-only plugins.
The plugin functions now take an errstr argument that can be used
to return an error string to be logged on failure or error.
