adbc5b5f71 tcp: tighten up checks for received SYN 
Any malicous segment could contain a SYN up to now (no check).
A SYN in the wrong segment could break OOSEQ queueing.
Fix this by allowing SYN only in states where it is required.

See bug #56397: Assert "tcp_receive: ooseq tcplen > rcv_wnd"

d281d3e959 PPP, EAP: ignore received EAP messages when not doing EAP 
This adds some basic checks to the subroutines of eap_input to check
that we have requested or agreed to doing EAP authentication before
doing any processing on the received packet.  The motivation is to
make it harder for a malicious peer to disrupt the operation of pppd
by sending unsolicited EAP packets.  Note that eap_success() already
has a check that the EAP client state is reasonable, and does nothing
(apart from possibly printing a debug message) if not.

2ee3cbe69c PPP, EAP: fix bounds check in EAP code 
Given that we have just checked vallen < len, it can never be the case
that vallen >= len + sizeof(rhostname).  This fixes the check so we
actually avoid overflowing the rhostname array.

61c67fc229 ip_forward: fix IPv4 forwarding with multiple netifs/offloading 
When we have multiple netifs where at least one has checksum offloading
capabilities, IP forwarding needs to set various checksum fields to 0
to prevent HW algorithms on calculating an invalid checksum.

-> set checksum fields of IP/UDP/TCP/ICMP to 0 in ip4_forward().

8d7e436a9d Fix select_waiting not being decremented for sockets closed while in lwip_select() 
See bug #57445. Short version of the description there: lwip_select() failed
to decrement 'select_waiting' of a socket since that code part failed on
'free_pending' sockets. However, the code does not have to check that as it
has marked the socket to be in use itself earlier.
