0a8b1c199d PPP, added missing cast on pbuf_header() 2015-04-26 23:42:18 +02:00

3a3c823ddb PPP, MPPE, try to use pbuf_header() in mppe_compress() 
If there is enough space in front of the buffer, use it instead of
allocating a new pbuf.

900f3c9a09 PPP, MPPE, don't issue CCP reset request in stateless mode 
This is useless, flushed bit is always true in stateless mode, we
don't need to issue a CCP reset request in this case.

8fe2f747f4 PPP, MPPE, issue CCP reset request if synchronization is lost 
If MPPE synchronization is lost, it is advised to send a CCP reset
request in order to recover to a clean state.

adaeff5540 PPP, MPPE, discard late packet in stateless mode 
When PPP is used over a link which does not guarantee packet ordering,
we might get late MPPE packets. This is a problem because MPPE must be
kept synchronized and the current implementation does not drop them and
rekey 4095 times instead of 0, which is wrong.

In order to prevent rekeying about a whole count space times (~ 4095
times), drop packets which are not within the forward 4096/2 window and
increase sanity error counter.

d0f91c00cb PPP, MPPE, sanity error path rework 
We are going to need sanity error path a little further, rework to be
able to use the sanity error path anywhere in decompressor.

beabd3c6b7 Added some macros with extension "_val" that work on actual instances and leave away the "if != NULL" check to get rid of gcc "-Waddress" warnings in the core code at least (I might not have caught all of them, yet) 2015-04-22 12:43:03 +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.

15cc47334e PPP, don't assert if we receive a too short packet in ppp_input(), just drop 
We might actually receive too short packets through PPPoE or PPPoL2TP,
don't assert on unusal packets, just drop them.

5989c1883e PPP, removed useless padding in bitfields 
Most of them were wrong actually. We have to use unsigned int because
C90 only allows int types for bitfields, so we are stuck to 32-bit
bitfields in most cases.

632de523de Fixed PBUF_LINK_ENCAPSULATION_HLEN support 
PBUF_LINK_ENCAPSULATION_HLEN support was introduced by 6ef7563f and
missed the fact that header size calculation/reservation using
computation like PBUF_LINK_HLEN + PBUF_IP_HLEN + ... are used all over
the source code. Hopefully fixed all of them.

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.
