Unfortunately, all functions were renamed when PolarSSL was renamed to
mbed TLS, breaking the API. In order to continue supporting our embedded
PolarSSL copy while allowing our users to use mbed TLS, we need a function
map to deal with the API break.
This commit add a function map for all hashes and ciphers we are currently
using.
We are going to need ppp_pcb* in MSCHAP and MSCHAPv2 for MPPE for
int mppe_keys_set, u_char mppe_send_key and u_char mppe_recv_key
which are currently global variable which must be moved to ppp_pcb.
Using cleaned PolarSSL md4/md5/sha1 implementations, without changing the API,
so that lwIP users already doing SSL or using PolarSSL don't need to compile
md4/md5/sha1 twice.
Added to that, we need a DES library for MSCHAP, and PolarSSL provided
a DES support.
And finally, PolarSSL is outstanding :-)
PPPoE works, PPPoS code is not ported at all.
I am using the RP-PPPoE server to do my tests using the following
configuration:
$ cat /etc/ppp/pppoe-server-options
debug
login
lcp-echo-interval 10
lcp-echo-failure 10
ms-dns 192.168.4.130
ms-dns 192.168.4.231
netmask 255.255.255.0
defaultroute
noipdefault
usepeerdns
$ cat /etc/ppp/allip
192.168.4.1-200
$ pppoe-server -C isp -L 192.168.4.254 -p /etc/ppp/allip -I tap0
Plus the usual auth-lines in /etc/ppp/pap-secrets and
/etc/ppp/chap-secrets .
And the unix port minimal "echo" project slightly modified to use
the "tcpip" API, so with threads, which I am going to commit with
NO_SYS as a -Dmacro.
It still use some of the linux'ism, such as syslog() and crypt(),
I do not want to drop the syslog() supports at the moment, this is
pretty useful to debug, and we may just convert the way the syslog() is
done to provide a trace feature to our PPP users, as a compile-time
option.
