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.

bf1285e3c9 ppp: don't link debug functions if disable
This converts all ppp_*() debug functions to ppp_*(()) macros that
ensure the code is left out by the linker if the corresponding debug
setting is disabled.

Downside is that many lines of code are touched, but since these
already differ to upstream PPP sources, I figured that's ok...
