1 The lwIP PPP support is based from pppd 2.4.5 (http://ppp.samba.org) with
2 huge changes to match code size and memory requirements for embedded devices.
4 Anyway, pppd has a mature codebase for years and the average commit count
5 is getting low on their Git repository, meaning that we can follow what
6 is happening on their side and merge what is relevant for lwIP.
8 So, here is the pppd follow up, so that we don't get away too far from pppd.
11 == Patch fetched from from pppd Debian packages ==
13 This has nothing to do with pppd, but we merged some good patch from
14 Debian and this is a good place to be.
16 - LCP adaptive echo, so that we don't send LCP echo request if we
17 are receiving data from peer, can be enabled by setting PPP_LCP_ADAPTIVE
20 - IPCP no/replace default route option, were added in the early stage of
21 the ppp port, but it wasn't really helpful and was disabled when adding
22 the new API ppp_set_default() call, which gives the lwIP user control over
23 which one is the default interface, it was actually a requirement if you
24 are doing PPP over PPP (i.e. PPPoL2TP, VPN link, over PPPoE, ADSL link).
26 - using rp-pppoe pppd exits with EXIT_OK after receiving a timeout waiting
27 for PADO due to no modem attached, bug reported to pppd bug tracker, fixed
28 in Debian but not in the latest (at the time when the port were started)
34 2010-03-06 - Document +ipv6 and ipv6cp-accept-local
35 e7537958aee79b3f653c601e903cb31d78fb7dcc
40 2010-03-06 - Install pppol2tp plugins with sane permissions
41 406215672cfadc03017341fe03802d1c7294b903
46 2010-03-07 - pppd: Terminate correctly if lcp_lowerup delayed calling
48 3eb9e810cfa515543655659b72dde30c54fea0a5
53 2010-03-07 - rp_pppoe: Copy acName and pppd_pppoe_service after option parsing
54 cab58617fd9d328029fffabc788020264b4fa91f
56 Don't care, is a patch for pppd/plugins/rp-pppoe/plugin.c which is not part
60 2010-08-23 - set and reset options to control environment variables
62 2b6310fd24dba8e0fca8999916a162f0a1842a84
64 We can't fork processes in embedded, therefore all the pppd process run
65 feature is disabled in the port, so we don't care about the new
66 "environment variables" pppd feature.
69 2010-08-23 - Nit: use _exit when exec fails and restrict values to 0-255
71 2b4ea140432eeba5a007c0d4e6236bd0e0c12ba4
73 Again, we are not running as a heavy process, so all exit() or _exit() calls
77 2010-08-23 - Fix quote handling in configuration files to be more like shell
79 3089132cdf5b58dbdfc2daf08ec5c08eb47f8aca
81 We are not parsing config file, all the filesystem I/O stuff were disabled
85 2010-08-24 - rp-pppoe: allow MTU to be increased up to 1500
86 fd1dcdf758418f040da3ed801ab001b5e46854e7
88 Only concern changes on RP-PPPoE plugin, which we don't use.
91 2010-09-11 - chat: Allow TIMEOUT value to come from environment variable
92 ae80bf833e48a6202f44a935a68083ae52ad3824
94 See 2b6310fd24dba8e0fca8999916a162f0a1842a84.
97 2011-03-05 - pppdump: Fix printfs with insufficient arguments
98 7b8db569642c83ba3283745034f2e2c95e459423
100 pppdump is a ppp tool outside pppd source tree.
103 2012-05-06 - pppd: Don't unconditionally disable VJ compression under Linux
104 d8a66adf98a0e525cf38031b42098d539da6eeb6
106 Patch for sys-linux.c, which we don't use.
109 2012-05-20 - Remove old version of Linux if_pppol2tp.h
110 c41092dd4c49267f232f6cba3d31c6c68bfdf68d
115 2012-05-20 - pppd: Make MSCHAP-v2 cope better with packet loss
116 08ef47ca532294eb428238c831616748940e24a2
118 This is an interesting patch. However it consumes much more memory for
119 MSCHAP and I am not sure if the benefit worth it. The PPP client can
120 always start the authentication again if it failed for whatever reason.
123 2012-05-20 - scripts: Make poff ignore extra arguments to pppd
124 18f515f32c9f5723a9c2c912601e04335106534b
126 Again, we are not running scripts.
129 2012-05-20 - rp-pppoe plugin: Print leading zeros in MAC address
130 f5dda0cfc220c4b52e26144096d729e27b30f0f7
132 Again, we are not using the RP-PPPoE plugin.
135 2012-05-20 - pppd: Notify IPv6 up/down as we do for IPv4
136 845cda8fa18939cf56e60b073f63a7efa65336fc
138 This is just a patch that adds plugins hooks for IPv6, the plugin interface
139 was disabled because we don't have .so plugins in embedded.
142 2012-05-20 - pppd: Enable IPV6 by default and fix some warnings
143 0b6118239615e98959f7e0b4e746bdd197533248
145 Change on Makefile for IPv6, warnings were already cleared during port.
148 2012-05-20 - contrib: Fix pppgetpass.gtk compilation
149 80a8e2ce257ca12cce723519a0f20ea1d663b14a
151 Change on Makefile, don't care.
154 2012-05-20 - pppd: Don't crash if crypt() returns NULL
155 04c4348108d847e034dd91066cc6843f60d71731
157 We are using the PolarSSL DES implementation that does not return NULL.
160 2012-05-20 - pppd: Eliminate some warnings
161 c44ae5e6a7338c96eb463881fe709b2dfaffe568
163 Again, we are handling compilation warnings on our own.
166 2012-05-20 - rp-pppoe plugin: Import some fixes from rp-pppoe-3.10
167 1817d83e51a411044e730ba89ebdb0480e1c8cd4
169 Once more, we are not using the RP-PPPoE plugin.
172 2013-01-23 - pppd: Clarify circumstances where DNS1/DNS2 environment variables are set

236 is about detaching from the terminal, which is out of the embedded scope.
239 2013-03-11 - pppd: Default exit status to EXIT_CONNECT_FAILED during connection phase
