587e0e3e0c PPP, CORE, beautified ppp_set_auth() 
Beautified, added PPPAUTHTYPE_MSCHAP_V2 choice support.

4bcddd72e6 PPP, CORE, cleaned ppp_close() function 
Calling new_phase() instead of assigning pcb->phase directly.
Removed redundant call to link status callback.

00bb70a62d PPP, CORE, functions ppp_set_netif_statuscallback() and ppp_set_netif_linkcallback() replaced with defines 
PPP is now pointerful for a while, we don't need anymore accessor functions
for the unique PPP local and static control block. Replaced
ppp_set_netif_statuscallback() and ppp_set_netif_linkcallback() functions to
defines.

Removed pppapi_do_ppp_set_netif_statuscallback() and
pppapi_do_ppp_set_netif_linkcallback(), they were useless because
netif_set_status_callback() and netif_set_link_callback() can be
safely called while PPP status is in dead (= non open) state
and even before the PPP session is actually created at all.

ec5cf8593e Continued chrysn's work: changed nearly all functions taking 'ip(X)_addr_t' pointer to take const pointers (changed user callbacks: raw_recv_fn, udp_recv_fn; changed port callbacks: netif_output_fn, netif_igmp_mac_filter_fn) 2015-02-22 21:46:35 +01:00

b0b7240022 PPP, PPPoS, moved advise about modem from pppos_create() to ppp_open() 
pppos_create() can be called whether the modem is ready to process the
PPP session since pppos_create() does not start the PPP session anymore,
moved the advise from pppos_create() to ppp_open().

4be7fccad3 PPP, CORE, ppp_close() and ppp_sighup() ended up sharing almost everything, merged 
Merged ppp_sighup() to ppp_close() using an optional argument  "nocarrier"
on ppp_close().

b040ace4c2 PPP, CORE, carrier lost signal, fixed FSM mismatch 
ppp_sighup() hard change the PPP FSM phase, it ends up with a FSM
mismatch if PPP is currently connecting or disconnecting.

Only do "sighup" on the stable running phase, fallback to the close
method. Handle special DEAD and HOLDOFF states as well.

ab572ce5b9 PPP, CORE, fixed PPP phase state machine when ppp_close() is called during HOLDOFF phase 
Aborting HOLDOFF leaves us at PPP_PHASE_DEAD, fixed.

a1c5415f8f PPP, CORE, disable VJ is PPP IPV4 is compiled out

if PPP IPv4 is not compiled.

5680808fb6 PPP, CORE, ppp_ioctl PPPCTLG_UPSTATUS command now returns true if only IPv6 is up 
PPPCTLG_UPSTATUS ioctl didn't return true if IPv6 was up and IPv4 down, fixed.

814bcc04ad PPP, CORE, using ip*_set_* functions instead of IP4_ADDR and SMEMCPY 
Now using lwIP helper functions on ip_addr_t and ip6_addr_t.

ee8a05c3c7 PPP, CORE, removed if_up and if6_up checks in sifdown() and sif6down() 
It can't hurt us, checking is useless.
 2015-02-21 23:53:40 +01:00
Sylvain Rochet
30c89310a6 PPP, CORE, IPv6, if_up flag used instead of if6_up for outgoing IPv6 packets, fixed 
We can have an IPv6 only PPP interface, checking if6_up instead of if_up fixes
IPv6 only setup.

ppp_netif_output() which were only used for common code between
ppp_netif_output_ip4() and ppp_netif_output_ip6() is not necessary
anymore, removed, reducing call stack by one.

a8e973f5d7 PPP, CORE, remove the user ability to set the PPP error code (PPPCTLS_ERRCODE) 
This is now totally useless, it was used for the PPP core code but it is not
used anymore, remove then the user ability to set the PPP error code through
PPPCTLS_ERRCODE.

dc2e700057 PPP, CORE, using u8_t on ioctl command instead of int 
We don't need an int here, all commands are between 0 and 255.

59b659b027 PPP, CORE, compile out auth support if none of auth protocols are enabled 
Added macro PPP_AUTH_SUPPORT, if none of auth protocols are enabled
(PAP, CHAP, EAP) we reduce PPP memory usage by compiling out all
struct fields and source code used for authentication.

f57d4818a4 PPP, using PPP netif->num number instead of ppp->num 
Saved 2 bytes of RAM if debug is enabled, we are now using the
netif->num number instead of using our own ppp->num

6b4db944dd PPP, using err_t return code instead of PPPERR_

b92fe3eecb PPP, CORE, new callbacks, send_config, recv_config, vj_config 
Removed some calls from PPP core to PPPoS low level protocols,
the const struct allows us to have more and more callbacks
without using more RAM.

baaa2592a6 PPP, PPPoS, removed xmit_accm, almost duplicate of out_accm 
xmit_accm was meant to be a user configurable asyncmap, it was actually
broken since the introduction of ppp_new by the way we now reset the PPP
initial state, looks like no one until now is needing it anymore. If
necessary we will reintroduce this feature later properly instead of a
dirty and ugly hack into the PPP code.
