2 years agoUse systemd's sd_notify with option up_sdnotify
Jacob Floyd [Sat, 11 Mar 2017 05:25:23 +0000 (23:25 -0600)]
Use systemd's sd_notify with option up_sdnotify

This adds an up_sdnotify option so that systemd services of
Type=notify can have pppd send the READY=1 signal to systemd
once a network protocol (typically IP) is up.

To use up_sdnotify, pppd must be compiled with SYSTEMD=y.

up_sdnotify is safe as a non-priveleged option because systemd will
ignore any notifications that it is not expecting. If systemd starts
pppd in a unit-file that is Type=notify, then (and only then) will it
handle the READY=1 signal. If systemd didn't start the process, it
ignroes any notifications unless the signaling process was started by a
service that systemd is monitoring (directly or indirectly, such as a
grandchild process in the same cgroup as a process that systemd started)
AND that service is Type=notify, AND that service is explicitly
configured to allow other processes to send a notification on behalf of
that service by setting NotifyAccess=all.

Also, the socket used is defined in an environment variable provided and
deleted by systemd, allowing system and user services to use a different
socket. I really don't think there's any way to use that socket (even via
the sd_notify api of their library) to gain elevated privileges.

Another reason that up_sdnotify is a non-priveleged option is for cases
where ppp should be started as a system service under a non-priveleged
account. There may be other issues with running ppp under other
accounts, but systemd does not require root--or other privileged--access
in order to use the notification feature. Instead the security for this
feature is provided at the process level in that systemd knows which
processes it did and did not start, and which processes those processes
started (ie other processes in the systemd unit's cgroup), as explained

pppd: Provide error() implementation in pppoe-discovery

defined in pppoe.h. Since pppoe-discovery is a standalone program not
linked with the rest of pppd, the only way this could build is by
linking to glibc's proprietary error(3) function instead of the function
of the same name (but with different arguments) defined in pppd/utils.c.

So with glibc this builds, but will probably crash when the assertion is
triggered. As the assertion is unlikely to fail, nobody has noticed.

<ms-dns1> <ms-dns2> <ms-wins> <ms-wins>]

with the last two lines repeating until the IPCP error limit is
reached. As you can see, the peer added two extra fields in the
ConfNak reply. This is allowed, and indeed the following sent
ConfReq packet reflects this. However, when the ConfAck packet
is received, pppd discards it as invalid, because of the ms-wins

This fixes it.

plugins/radius: Handle bindaddr keyword in radiusclient.conf

This adds code to the radius plugin to handle the bindaddr keyword in
/etc/radiusclient/radiusclient.conf, thus allowing the administrator
to specify which local IP address to use when sending packets to the
radius server.

This is very common for setups where the router has multiple
interfaces for upstream and you don't know which connection is active.
In this case sometimes the packet uses the IP of interface 1 and
sometimes uses the IP of interface 2.  With this patch (adapted from
radiusclient-ng) you can specify the IP of the loopback address, and
the plugin will bind to that IP and send the packet with a fixed IP
every time.

The problem with the current poff script is on line 93 where the

that grep searches for prevents the PID of the specified pppd process

/usr/bin/poff: I could not find a pppd process for provider 'cit-vpn'.
None stopped.

The reason for this is that the " *\$" at the end of the regular

unusual in that the authenticatee's CHAP-Response contains what is
effectively a challenge to the authenticator, and the authenticator's
CHAP-Success packet contains a response to that challenge.  Having

(b) cope with a CHAP-Success packet that corresponds to one of our

MTU is checked and used to lower the configured MTU/MRU.

If MIN(MTU/MRU) is > 1492, PPP-Max-Payload is added to PADI and
PADR. If PPP-Max-Payload is received in PADO or PADS, it will be
used to lower the configured MTU/MRU as required.

The MTU/MRU settings are stored and reloaded whenever a connection
is made, to allow for the peer or interface MTU/MRU to increase if
used with persist option.

Conforming to RFC4638, if no PPP-Max-Payload is received, the

pppd: Terminate correctly if lcp_lowerup delayed calling fsm_lowerup

Cameron Hutchison noticed that if pppd gets asked to terminate the
link in the period between when lcp_lowerup() is called and when
fsm_lowerup() is called from lcp_delayed_up() (i.e. when listen_time
is non-zero), pppd never exits.

The reason is that lcp_close() doesn't handle the delayed-up case
properly.  Since the FSM is still in STOPPED state, we don't call
lcp_finished() and therefore never exit the main event loop.

This fixes it by handling the delayed-up case in lcp_close() as if
we had done the lowerup but the OPT_SILENT bit was set.  We use the
silent case because we don't want to actually send a configure-request
