435a0b98ac PPP, MPPE, cleaning license notice 
We only need to keep the BSD license part in lwIP, cleaning the part which
is only relevant for the Linux kernel.

05eda236cc PPP, MPPE, import unmodified Linux MPPE encoder/decoder 
This file, which is an unmodified copy of Linux MPPE encoder/decoder, is
licensed under a dual License BSD/GPL model. It was previously in the
pppd source tree and it was removed because this is merged into the Linux
kernel.

f967933e8b PPP, PPPoS, protect open flag in connect() and listen() 
Protect open flag in connect() and listen(), this is a bitfield, it might
not be set atomically on some targets.

ad56a115be PPP, CCP, moved ccp_test() from ccp_addci() to ccp_resetci() 
We don't need to test our available compression protocols that much, we know
what we are going to be able to use in embedded. Even PPPd don't need that.

Checking only in ccp_resetci() is enough, this way we know our cilen size
before ccp_addci() is called. PPPd is designed that *_addci() can use less
bytes than it previously asked in *_cilen(), we prefer to avoid that here.

We actually don't need at all ccp_test() calls, we know what we are
able to support at compile time, we don't need to ask the kernel like
PPPd does. This is just the first step in ccp_test() removal.

c8ed013600 PPP, FSM, added assert to easily track cilen size mismatch 
See c49fc8d for such a problem which ends up with heap corruption.

c49fc8db72 PPP, CCP: Fix ccp_cilen returning size if both deflate_correct and deflate_draft are enabled 
This fixes a bug returning 4 byte less than necessary for the addci buffer
if both deflate_correct and deflate_draft are enabled.

86970a01d7 etharp: reduce ARP aging timeout from 20 minutes to 5 minutes, since this is a time obviously used in some switches as MAC learning table timeout. Having our ARP timeout higher than this can lead to sending unicast packets to multiple network segments. 2015-03-24 20:04:18 +01:00

440c99100b fixed bug #34617: Stable etharp entries that are about to expire are now refreshed using unicast to prevent unnecessary broadcast. 
Only if no answer is received after 15 seconds, broadcast is used.

ee752ab1ce PPP, PPPoS, renamed PPP_INPROC_MULTITHREADED to PPP_INPROC_IRQ_SAFE 
Follow-up of the #44565 bug fix, renamed the misnamed
PPP_INPROC_MULTITHREADED to PPP_INPROC_IRQ_SAFE because it is
IRQ safe but not thread safe.

Updated PPP documentation which now clearly state when and how
this feature can be used.

6a04357547 PPP, PPPoS, reworked output path, reduced serial tx pbuf buffers to 1 
We actually allocated a pbuf chain only to iterate later the linked list
calling sio_write() for each pbuf, improved by calling sio_write() when
buffer is full and by recycling the pbuf, therefore only using one pbuf
for PPPoS output path.

Reworked pppos_write() and pppos_netif_output() to share more common
code into pppos_output_append() and pppos_output_last().

e27ab3a24f PPP, PPPoS, disable TCPIP API if PPP_INPROC_MULTITHREADED is true 
If PPP_INPROC_MULTITHREADED is true, then user does not what to use
the TCPIP API. Disabling the TCPIP API helps the user to understand
that PPP_INPROC_MULTITHREADED must not be used if he wish to use
the TCPIP API.
