f337cc1380 sched/clock/ timekeeping: Use clock_basetime() to initialize g_clock_wall_time to get the best initial RTC value and initialize g_clock_last_counter too since the hardware may not start counting from zero. 2018-11-12 07:00:41 -06:00

2bc709d4b9 sched/clock/clock_initialize.c: clock_inittime() needs to be done with CONFIG_SCHED_TICKLESS and clock_initialize should skip clock_inittime() for external RTC case since the RTC isn't ready yet. 2018-11-12 06:55:53 -06:00

002f09f2da net/mld: Fix logic error when testing for the case where all members have left. Still does not work. The end result is that the query timer no longer stops. Not when another another querier with a lower IP is present or when all of the members have left. Basically just can't stop querying under any condition. 2018-11-11 12:43:12 -06:00

bfa8c362c6 net/devif/devif_loopback.c: Fix warning: implicit declaration of memcmp. 2018-11-11 11:56:37 -06:00
Gregory Nutt
8a3fc26b74 Squashed commit of the following: 
The MLD implementation did not follow the RFC correctly when it is the Querier.  The Querier should use a general query and get query messages from all members of all groups.  This would be driven by a single timer per sub-nset since all groups are queried at once. Instead, the design used a Multicast Address Specific Query with one timer per group and ignores groups that we are not members of.

    Similary, the MLDv1 compatibility timer should be a single, separate timer, not a per-group timer.

    net/mld: Group may be NULL when sending a general query

8cfb376f81 net/mld: There is an issue with the general query timer design. There should be a single instance, not a per-group instance of the timer (ditto for the v1 compatibility timer). Fall back for now and use the per-group MAX query. 2018-11-10 12:13:54 -06:00

854046a931 /net/devif/ipv6_input.c: Correct handling of IPv6 extension headers. The main confusion was that the payload length in the IPv6 header does not include its extension headers. 
net/icmpv6/icmpv6_input.c:  Correct caculation of the ICMPv6 header address
    net/mld/mld_query.c:  Correct back test for group found.
    net/mld/mld_report.c: Fix host vs. network order problem.
    net/mld/mld_send.c: Correct the address used in sending the General Query.  It should be the unspecified address in that case.
    net/mld:  Querying workaround.  The MLD implementation does not follow the RFC correct when it is the Querier.  The Querier should use a general query and get query messages from all members of all groups.  This would be driven by a single timer since all groups are queried at once.  Instead, the design currently uses a Multicast Address Specific Query with one timer per group and ignores groups that we are not members of.

f4a3541d26 drivers/power/pm_initialize.c: Fix pm_domain_s.stime unint caused time error. Bug deatil: 
1. open CONFIG_DEBUG_FEATURES CONFIG_SYSTEM_TIME64 CONFIG_CLOCK_MONOTONIC
     ==> INITIAL_SYSTEM_TIMER_TICKS very big data, not zero
  2. close CONFIG_SCHED_TICKLESS
     ==> use g_system_timer as system clock
  3. pm_domain_s.stime init to zero
  4. clock_systimer() - pm_domain_s.stime get big data, error

68a115aed9 net/icmpv6/icmpv6_autoconfig.c and icmpv6_rnotify.c: Don't take the network device down when reconfiguring only the IP address from within ICMPv6 logic. Recommended by Xiang Xiao in order to avoid the long delays of bringing some networks back up. 
Normally it is required that the network be in the "down" state when re-configuring the network interface.  This is thought not to be a necessary here because.

  1. The ICMPv6 logic here runs with the network locked so there can be no outgoing packets with bad source IP addresses from any asynchronous network activity using the device being reconfigured.
  2. Incoming packets depend only upon the MAC filtering.  Network drivers do not use the IP address; they filter incoming packets using only the MAC address which is not being changed here.

71e1056e6d net/icmpv6, neighbor, and netdev: Rename netdev_dev_lladdrsize() to netdev_lladdrsize() and move the prototype to include/nuttx/nex/netdev.h, giving is global scope within the OS.
