e8399416ae PPP, magic, renamed random_bytes() to magic_random_bytes() for API coherency 2015-08-30 21:09:39 +02:00
Sylvain Rochet
d0fa8acf86 PPP, magic, enables building without PPP_MD5_RANDM support 
The only API difference with and without the PPP_MD5_RANDM support is the
availability of the random_bytes() function. Added a random_bytes()
function on top of magic() when PPP_MD5_RANDM support is not enabled,
thus allowing builds for both cases.

PPP_MD5_RANDM is still enabled by default (it was mandatory) if a protocol
using encryption is enabled, such as CHAP, EAP, or L2TP auth support.

ced7bef274 PPP, magic, MD5 random pool size cannot be anything else than MD5 hash size, code cleaning to make it clear 2015-08-30 21:09:39 +02:00

311644f39b PPP, PPPoS, remove magic_randomize() from PPPoS, it is already called in ppp_input() 
There is no point of calling magic_randomize() for each pppos_input()
call, making magic_randomize() potentially called for each serial input
byte which is quite a bad idea since magic_randomize() is quite
intensive in processing time (MD5 computation) compared to HDLC frame
parsing. There is no entropy added when being called for each input byte
rather than for each valid input packet because byte input is a
monotonic event at the packet level. Well, if packet arrival time is a
valid entropy source even so, which I doubt a lot, but we don't really
have anything else and we really need random for PPP authentication
layers.

987f6237c4 PPP, MPPE, drop input/output packets if we couldn't find the chosen decompressor/compressor 
Drop input/output packets if we couldn't find a decompressor/compressor,
it can't really happen because we only negotiate what we are able to
compress/decompress, but for the sake of code consistency it makes much
more sense to do so.

97ef85c9aa PPP, MPPE, fixed TCP over MPPE 
We used to modify in place the packet payload during encryption, it works
well for UDP and ICMP but TCP stack requires that we don't change the
packet payload, therefore we now copy the whole packet before encryption.

0ab21da820 Add multicast support to loopif 
This commit adds support to send and receive multicast on the loopback
netif by enabling IGMP via NETIF_FLAG_IGMP

This commit also introduces an LwIP configuration option,
LWIP_LOOPIF_MCAST, to control the behavior and it defaults to off

177c06b1f1 - prework for fixing bug #45029: access IPv4 configuration of struct netif via new API (netif_ip4_addr()/netif_ip4_netmask()/netif_ip4_gw()) instead of accessing the struct member directly. This way, we can change the struct member types from ip4_addr_t to ip_addr_t; 
- fixed some bugs in calls to ip4_addr*() where the cast to u8_t* did not reveal the wrong address type

d850efdd08 IPv6 sockaddr clean ups 
This commit address two issues with sockaddr struct implementations for
IPv6:

  1) struct sockaddr_in6 should have 32-bit unsigned field sin6_scope_id
     as specified in Section 3.4 of RFC 3493 (Basic Socket Interface
	 Extensions for IPv6)
  2) struct sockaddr is not extended in IPv6 to contain space for
     struct sockaddr_in6.  Applications should be using struct
	 sockaddr_storage when needing generic storage.  This removes the
	 extra bytes added when LWIP_IPV6 is defined
