bb0ba64fb0 Work on bug #52748: the bug in timeouts.c - apply Douglas' patch for absolute timeouts with modification to avoid cyclic timer overload situation 2018-01-08 12:48:48 +01:00

5eced48869 Apply timeouts.c simplification from Douglas 
Use TIME_LESS_THAN() macro instead of TIME_LESS_OR_EQUAL_THAN, it is more readable and results equivalent

a31f8837b5 Partly apply patch from "Douglas" provided in bug #52748: the bug in timeouts.c 
- Fix sys_untimeout implementation should not modify timer values since we are now using absolute timeouts.c
- Cleanup and simplify sys_check_timeouts() implementation
- Implement sys_restart_timeouts to rebase all timeouts based on next timer to expire

Changes by me:
- Rename TIME_LESS_THAN to TIME_LESS_OR_EQUAL_THAN

eaca067c7d Make _cyclic_ timers interval more deterministic - next timeout is calculated from last due time instead of relative to current time

This can be used to post preallocated messages from an ISR to the tcpip thread
when using FreeRTOS, where where calls differ between task level and ISR level.

2cb220d7fe netif: Move LWIP_ASSERT_CORE_LOCKED out of static functions 
The netif_do_set_{ipaddr|netmask|gw} are static functions what won't be called
directly, thus move LWIP_ASSERT_CORE_LOCKED to netif_set_{ipaddr|netmask|gw}.
This avoid duplicated LWIP_ASSERT_CORE_LOCKED checking by netif_set_addr().

d569a22c73 tcpip: ensure core is locked for init done function 
This ensures the core is locked when executing the init done function
passed to tcpip_init

The could manifest as a synchronization issue during early init if
another thread was in the LwIP context at the same time

d87740bb96 mdns: Fix multicast destination check for IPv6 
This broke when IPv6 got scopes added. Scopes/zones are checked
even if none of the compared addresses are link local.

Result of the bug was that IPv6 replies were always sent unicast to
the source instead of to the multicast address.

Add ip-generic version that ignores IP zone info, since the v6 group
address is not tied to any netif.

04b983b4f3 tcp: handle pcb->snd_queuelen and chained pbufs during segment split (bug #52692) 
This fixes a bug in tcp_split_unsent_seg() where a chained pbuf was
not correctly updating pcb->snd_queuelen during trimming and snd_queuelen
would desynchronize if pbuf_realloc() freed some of the chain

Also, use pbuf_clen() for adding the new remaining segment rather than ++.
The new remaining segment should always be one pbuf due to the semantics
of PBUF_RAM, but this follows the best practice of using pbuf_clen()

b536fd9767 Apply modified version of bug #52747: mdns resp: separate the announce function and add netifapi support for it 
Changes made by me:
- Move all error handling code into mdns_resp_announce() so it can be safely used by external code
- Remove mdns_resp_netif_settings_changed() because it is the same as mdns_resp_announce() after my changes
- Declare #define for a "thread-safe" version of mdns_resp_announce in mdns.h instead of netifapi.h - I don't want to intermix netif API with APPs
