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.
|
---|
3 |
|
---|
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.
|
---|
7 |
|
---|
8 | So, here is the pppd follow up, so that we don't get away too far from pppd.
|
---|
9 |
|
---|
10 |
|
---|
11 | == Patch fetched from from pppd Debian packages ==
|
---|
12 |
|
---|
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.
|
---|
15 |
|
---|
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
|
---|
18 | to true.
|
---|
19 |
|
---|
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).
|
---|
25 |
|
---|
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)
|
---|
29 | pppd release.

|
---|
55 |
|
---|
56 | Don't care, is a patch for pppd/plugins/rp-pppoe/plugin.c which is not part
|
---|
57 | of the port.
|
---|
58 |
|
---|
59 |
|
---|
60 | 2010-08-23 - set and reset options to control environment variables

62 | 2b6310fd24dba8e0fca8999916a162f0a1842a84
|
---|
63 |
|
---|
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.
|
---|
67 |

68 |
|

69 | 2010-08-23 - Nit: use _exit when exec fails and restrict values to 0-255

71 | 2b4ea140432eeba5a007c0d4e6236bd0e0c12ba4
|
---|
72 |

|
---|
116 | 08ef47ca532294eb428238c831616748940e24a2
|
---|
117 |
|
---|
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.
|

121 |

138 | This is just a patch that adds plugins hooks for IPv6, the plugin interface
