6 years agokernel - Fix network lockup due to msgport bug
Matthew Dillon [Fri, 22 Feb 2013 02:14:45 +0000 (18:14 -0800)]
kernel - Fix network lockup due to msgport bug

* Netisr threads (i.e. arp thread) which issue route table updates
  use a synchronous netmsg from a 'spin' type port to a 'thread' type
  port.

  When going spin->thread, the lwkt_thread_putport*() code was not
  using an atomic op to manipulate ms_flags.  This could interfere
  with the originator on the spin port issuing a lwkt_spin_waitmsg()
  and cause one or more flags to be lost.

  Ensure that lwkt_thread_putport*() uses atomic ops when manipulating
  ms_flags.

* Another serious issue is that the lwkt_*_waitmsg() code was testing
  MSGF_QUEUED outside of its port lock.  This flag can only be tested
  while the port is locked.

* lwkt_thread_replyport() must use an atomic op when setting
  MSGF_INTRANSIT and MSGF_REPLY to avoid SMP races on ms_flags
  updates.

* lwkt_thread_replyport() requires a critical section against
  possible preemption when adjusting ms_flags.

* lwkt_forwardmsg() does not need a critical section.

* Other notes: Not all ms_flags manipulation needs an atomic op.  For
  example, when initializing a new message or when a lock is held to
  rendezvous at a reply port when replying.  However, all 'put' and 'wait'
  interactions on messages absolutely require atomic ops when manipulating
  ms_flags.

  Finally, note that all msgport queue operations use atomic ops to
  adjust MSGF_QUEUED when adding or removing a message to a port queue.

6 years agokernel - Fix issue with ARP packets stalling out entire network
Matthew Dillon [Thu, 21 Feb 2013 23:33:26 +0000 (15:33 -0800)]
kernel - Fix issue with ARP packets stalling out entire network

* ARP packets can cause ARP routing table updates to occur.  An ARP
  routing table update is an expensive synchronous netmsg that is
  forwarded through *ALL* cpus.

* ARP was previously being handled by netisr 0 and on large multi-way
  machines (aka monster the 48-way opteron) under very heavy loads this
  could result in very long stalls for any packet processing forwarded
  to cpu 0.

  Stalls exceeding 200 seconds were observed on monster when a large
  number of ARP packets had to be processed.

* Implement a dedicated thread feature for the NETISR mechanism and
  modify NETISR_ARP to use it.  This takes the expensive synchronous
  ARP packet processing off the general per-cpu netisr threads.
  This thread currently runs on cpu (18 % ncpus) (NETISR_ARP == 18).

  Thus the general per-cpu (netisr 0) thread will no longer stall
  on ARP packets.

* ping latencies under extreme loads improved to (approximately):

  ping -i 0.001 monster-nr
  11735 packets transmitted, 11735 packets received, 0.0% packet loss

backed up.  If they haven't, "make installworld" will fail to execute
explaining that the system should be backed up.  If a previous backup
does exist, but it's older than the specified number of days, "make
installworld" will fail explaining the backup needs to be refreshed.

Passing NO_BACKUP through the command line or make.conf will inhibit
these checks.
