The lwIP PPP support is based from pppd 2.4.5 (http://ppp.samba.org) with
|
|
huge changes to match code size and memory requirements for embedded devices.
|
|
|
|
Anyway, pppd has a mature codebase for years and the average commit count
|
|
is getting low on their Git repository, meaning that we can follow what
|
|
is happening on their side and merge what is relevant for lwIP.
|
|
|
|
So, here is the pppd follow up, so that we don't get away too far from pppd.
|
|
|
|
|
|
== Patch fetched from from pppd Debian packages ==
|
|
|
|
This has nothing to do with pppd, but we merged some good patch from
|
|
Debian and this is a good place to be.
|
|
|
|
- LCP adaptive echo, so that we don't send LCP echo request if we
|
|
are receiving data from peer, can be enabled by setting PPP_LCP_ADAPTIVE
|
|
to true.
|
|
|
|
- IPCP no/replace default route option, were added in the early stage of
|
|
the ppp port, but it wasn't really helpful and was disabled when adding
|
|
the new API ppp_set_default() call, which gives the lwIP user control over
|
|
which one is the default interface, it was actually a requirement if you
|
|
are doing PPP over PPP (i.e. PPPoL2TP, VPN link, over PPPoE, ADSL link).
|
|
|
|
- using rp-pppoe pppd exits with EXIT_OK after receiving a timeout waiting
|
|
for PADO due to no modem attached, bug reported to pppd bug tracker, fixed
|
|
in Debian but not in the latest (at the time when the port were started)
|
|
pppd release.
|
|
|

2010-03-07 - rp_pppoe: Copy acName and pppd_pppoe_service after option parsing
|
|
cab58617fd9d328029fffabc788020264b4fa91f
|
|
|
|
Don't care, is a patch for pppd/plugins/rp-pppoe/plugin.c which is not part
|
|
of the port.
|
|
|
|
|
|
2010-08-23 - set and reset options to control environment variables
|
|
for scripts.
|
|
2b6310fd24dba8e0fca8999916a162f0a1842a84
|
|
|
|
We can't fork processes in embedded, therefore all the pppd process run
|
|
feature is disabled in the port, so we don't care about the new
|
|
"environment variables" pppd feature.
|
|
|
|
|
|
2010-08-23 - Nit: use _exit when exec fails and restrict values to 0-255
|
|
per POSIX.
|
|
2b4ea140432eeba5a007c0d4e6236bd0e0c12ba4
|
|
|
|
Again, we are not running as a heavy process, so all exit() or _exit() calls
|
|
were removed.
|
|
|
|
|
|
2010-08-23 - Fix quote handling in configuration files to be more like shell
|
|
quoting.
|
|
3089132cdf5b58dbdfc2daf08ec5c08eb47f8aca
|
|
|
|
We are not parsing config file, all the filesystem I/O stuff were disabled
|
|
in our port.
|
|
|
|
|
|
2010-08-24 - rp-pppoe: allow MTU to be increased up to 1500
|
|
fd1dcdf758418f040da3ed801ab001b5e46854e7
|
|
|

Only concern changes on RP-PPPoE plugin, which we don't use.
|

|
|
d8a66adf98a0e525cf38031b42098d539da6eeb6
|
|
|
|
Patch for sys-linux.c, which we don't use.
|
|
|
|
|
|
2012-05-20 - Remove old version of Linux if_pppol2tp.h

2012-05-20 - pppd: Make MSCHAP-v2 cope better with packet loss
|
|
08ef47ca532294eb428238c831616748940e24a2
|
|
|
|
This is an interesting patch. However it consumes much more memory for
|
|
MSCHAP and I am not sure if the benefit worth it. The PPP client can
|
|
always start the authentication again if it failed for whatever reason.
|
|
|
|
|
|
2012-05-20 - scripts: Make poff ignore extra arguments to pppd
|
|
18f515f32c9f5723a9c2c912601e04335106534b

|
|
845cda8fa18939cf56e60b073f63a7efa65336fc
|
|
|
|
This is just a patch that adds plugins hooks for IPv6, the plugin interface
|
|
was disabled because we don't have .so plugins in embedded.
|
|
|
|
|
|
2012-05-20 - pppd: Enable IPV6 by default and fix some warnings
