3686110ed2 PPP, SERVER: statically define our name for authentication purposes 
We don't need that in RAM nor a pointer to a string, a static
define is fine for embedded devices, saved ~257 bytes of RAM.

e86a0a4325 PPP, CORE, SERVER, set auth configuration before auth 
Set LCP wanted options accordingly to the user auth configuration
if peer is required to authenticate itself.

8d05279599 PPP, CORE, moved auth configuration from auth_reset() to lcp_resetci() 
Prepare for PPP_SERVER support, we need to move auth configuration before
lcp_allowoptions is copied into lcp_gotoptions. Restore unused
auth_reset() function using pppd original source code.

5a71509353 PPP, CORE, IPCP: removed useless ask_for_local boolean 
We don't need ask_for_local boolean, this is only useful for setup which
can determine the local IP address from the system hostname, which is
probably meaningless for embedded devices (and probably any devices).

It was actually only set by ip_check_options() which is commented out in
lwIP because we don't parse a config file nor check PPP configuration
(user is responsible about writing a configuration which is logical ;-).
Furthermore ask_for_local boolean never set actually had the wrong
default for PPP server setups.

2aabe16163 PPP, PPPoS, removed ppp_accm_mask[], saved a few bytes of ROM 
This was a pretty naive way of doing a bitshift, code is smaller if we let
the compiler decide.

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.

65095253a9 PPP, fixed warnings introduced by const pointers on ip_addr_t 2015-02-22 22:38:02 +01:00
sg
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.
 2015-02-22 13:54:52 +01:00

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 
VJ compression is only supported for PPP IPv4, compile out VJ support
if PPP IPv4 is not compiled.

00e8988b52 PPP, IPv4 support is now optional 
New compile time option: PPP_IPV4_SUPPORT

PPP IPv4 support can now be compiled out.

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.

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.
 2015-02-21 21:48:53 +01:00

c4d1354c54 PPP, CORE, don't use ppp_ioctl() from PPP core, assign pcb->err_code instead 
Removed useless calls to ppp_ioctl(pcb, PPPCTLS_ERRCODE, …), we now assign
pcb->err_code directly instead. ppp_ioctl() is not linked anymore if user
application don't use it.

dc2e700057 PPP, CORE, using u8_t on ioctl command instead of int

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.

netif->num number instead of using our own ppp->num
