2b5250dd9d Fix bug #47507: PPP API does not support LWIP_MPU_COMPATIBLE 
I'd be glad if someone would test it :-)
Sylvain, if you don't like this patch feel free to revert it

953b7bdd59 Implement UDP dual-stack PCB support 
Create special IP address type "IPADDR_TYPE_ANY" for it.
SNMP uses new feature in non-netconn mode.

TODO: Same for TCP & RAW, adapt NETCONN to use this feature

c4d78e6422 PPP, PPPoL2TP, fix double free of L2TP pcb in pppol2tp_create error path 
ppp_free() calls the low level protocol destroy function, pppol2tp_destroy()
here, which freed the l2tp pcb, followed by pppol2tp_create which also freed
the pcb.

Fixing it by reordering the L2TP init so we don't have to call ppp_free()
anymore.

8a0fb03e21 Separate mib2 counter/table callbacks from snmp agent. This both cleans up the code and should allow integration of a 3rd party agent/mib2. 2015-09-08 09:47:30 +02:00

5e43e2d333 PPP, L2TP, minor fixes 
Check tot_len for ZLB instead of len, it might happens we are just
between 2 pbuf, although almost impossible.

Check buffer is at least 2 byte long before checking address & flags
header.

b302cad46d PPP, VJ, CCP: rework to fix protocol order 
We need to do VJ compression before CCP/MPPE compression and VJ
decompression after CCP/MPPE decompression. This leads to a massive
rewrite of how we currently handled VJ only in the PPPoS lower protocol
handler.

Moved VJ structures from pppos to ppp_pcb because we need them back in
PPP core. This is a bit unfortunate because that's not necessary for
PPPoE or PPPoL2TP, but, hey!. Fixed CCP+MPPE+VJ order.

bc99f75b53 PPP, PPPoL2TP, removed unnecessary single pbuf 
Removed ppp_singlebuf() in pppol2tp_input(), chained pbuf are perfectly
acceptable for IP data and we are currently supporting them perfectly
for PPPoS. The PPP stack itself (LCP, IPCP et al.) does not support
chained pbuf and is already calling ppp_singlebuf() just before passing
packet to the protocol handler.

Added ppp_singlebuf() in pppol2tp_dispatch_control_packet() because we
do not support chained pbuf in L2TP control packet.

efe229a54b PPP, PPPoL2TP, merged pppol2tp_input_ip() to pppol2tp_input() 
We don't need anymore an input function for ip4 and an input function
for ip6, work to achieve that was partially done by ce7e31cd.
pppol2tp_input() is now only called by pppol2tp_input_ip(), finishing
dual stack support by merging pppol2tp_input_ip() into pppol2tp_input().

d6fdf7d4b1 PPP, PPPoL2TP, switched to dual stack IPv4/IPv6 
Replaced ip4_addr_t to ip_addr_t in pppapi_pppol2tp_create() prototype,
now binding to UDPv6 or UDPv4 depending on the passed ip_addr_t type.

Removed pppol2tp_create_ip6() and pppapi_pppol2tp_create_ip6().

ce7e31cd04 task #12722 (improve IPv4/v6 address handling): renamed ip_addr_t to ip4_addr_t, renamed ipX_addr_t to ip_addr_t and added IP version; 
ip_addr_t is used for all generic IP addresses for the API, ip(4/6)_addr_t are only used internally or when initializing netifs or when calling version-related functions
