896535fe87 Fixed dhcp unit tests after changing netif up/down handling 2015-03-06 07:38:51 +01:00
Sylvain Rochet
89434f6a2f PPP, CORE, call netif_set_up() after if4_up and if6_up flags are set, to prevent dropping packets 
lwIP core might send packet when calling netif_set_up(), don't drop packets
anymore in ppp_netif_output_ip4() and ppp_netif_output_ip6() because flags
are cleared.

4e520cdd30 fixed bug #37068 (netif up/down handling is unclear): correclty separated administrative status of a netif (up/down) from 'valid address' status ATTENTION: netif_set_up() now always has to be called, even when dhcp/autoip is used! 2015-03-05 20:57:43 +01:00

b09c891290 PPP, PPPoE, removed devname variable from pppoe_disc_input() 
Only used for debug, reworked in a more clever way. It was actually broken
by design: setting an interface integer into a string without formatting
was quite a dumb idea.

d28bb04a9c PPP, PPPoE, improve reliability if we receive a PADT 
Don't disconnect when we receive a PADT, we let the LCP Echo/Reply find
the fact that PPP session is down. Asking the PPP stack to end the
session require strict checking about the PPP phase to prevent endless
disconnection loops.

Luckily it previously does nothing because PADT frames are rarely sent
with a hunique tag and we only set the sc pointer if we receive a
hunique tag.

9de1c71ff7 PPP, PPPoE, removed global static buffer only used for debug

moved to stack.

1bee131d52 PPP, L2TP, using LNS chosen destination port 
L2TP LNS might chose its own local port, we actually stored
the port the LNS wanted to use but we never used it.

2731976a95 PPP, renamed ppp_open to ppp_connect 
Makes it clear we are initiating the PPP session with ppp_connect
(i.e. acting as a PPP client) so there is no confusion possible
between ppp_connect and ppp_listen.

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.

8d05279599 PPP, CORE, moved auth configuration from auth_reset() to lcp_resetci()

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

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.
