22 Description: Change ptllnd timeout and watchdog timers
23 Details : Add ptltrace_on_nal_failed and bump ptllnd timeout to match
28 Description: One down Lustre FS hangs ALL mounted Lustre filesystems
29 Details : Shared routing enhancements - peer health detection.
31 Severity : enhancement
33 Description: acceptor.c cleanup
34 Details : Code duplication in acceptor.c for the cases of kernel and
35 user-space removed. User-space libcfs tcpip primitives
36 uniformed to have prototypes similar to kernel ones. Minor
37 cosmetic changes in usocklnd to use cfs_socket_t as
38 representation of socket.
42 Description: IB path MTU mistakenly set to 1st path MTU when ib_mtu is off
43 Details : See comment 46 in bug 11245 for details - it's indeed a bug
44 introduced by the original 11245 fix.
48 Description: uptllnd credit overflow fix
49 Details : kptl_msg_t::ptlm_credits could be overflown by uptllnd since
54 Description: socklnd protocol version 3
55 Details : With current protocol V2, connections on router can be
56 blocked and can't receive any incoming messages when there is no
57 more router buffer, so ZC-ACK can't be handled (LNet message
58 can't be finalized) and will cause deadlock on router.
59 Protocol V3 has a dedicated connection for emergency messages
60 like ZC-ACK to router, messages on this dedicated connection
61 don't need any credit so will never be blocked. Also, V3 can send
62 keepalive ping in specified period for router healthy checking.

82 Description: workaround for OOM from o2iblnd
83 Details : OFED needs allocate big chunk of memory for QP while creating
84 connection for o2iblnd, OOM can happen if no such a contiguous
86 QP size is decided by concurrent_sends and max_fragments of
87 o2iblnd, now we permit user to specify smaller value for

106 quite long before timing out.
110 Description: Continuous recovery on 33 of 413 nodes after lustre oss failure
111 Details : Lost reference on conn prevents peer from being destroyed, which
112 could prevent new peer creation if peer count has reached upper

401 Description: Initialize cpumask before use
405 Description: ASSERTION failures when upgrading to the patchless zero-copy
407 Details : This bug affects "rolling upgrades", causing an inconsistent
408 protocol version negotiation and subsequent assertion failure
409 during rolling upgrades after the first wave of upgrades.
413 Details : Change "dropped message" CERRORs to D_NETERROR so they are
414 logged instead of creating "console chatter" when a lustre
415 timeout races with normal RPC completion.
418 Details : lnet_clear_peer_table can wait forever if user forgets to
422 Details : libcfs_id2str should check pid against LNET_PID_ANY.
426 Description: added LNET self test

440 Description: make panic on lbug configurable
444 Description: Add OFED1.2 support to o2iblnd
445 Details : o2iblnd depends on OFED's modules, if out-tree OFED's modules
446 are installed (other than kernel's in-tree infiniband), there

450 this link provides solution:
451 https://bugs.openfabrics.org/show_bug.cgi?id=355
452 if extra Module.symvers is not supported in kernel, we will

470 mxlnd - MX 1.2.1 or later,
471 ptllnd - Portals 3.3 / UNICOS/lc 1.5.x, 2.0.x
475 Description: Ptllnd didn't init kptllnd_data.kptl_idle_txs before it could be
476 possibly accessed in kptllnd_shutdown. Ptllnd should init
477 kptllnd_data.kptl_ptlid2str_lock before calling kptllnd_ptlid2str.
481 Description: gmlnd ignored some transmit errors when finalizing lnet messages.
485 Description: ptllnd logs a piece of incorrect debug info in kptllnd_peer_handle_hello.
489 Description: the_lnet.ln_finalizing was not set when the current thread is
490 about to complete messages. It only affects multi-threaded
496 Description: Changed the default kqswlnd ntxmsg=512
501 Description: Assertion failure in kernel ptllnd caused by posting passive
502 bulk buffers before connection establishment complete.
507 Description: A race in kernel ptllnd between deleting a peer and posting
508 new communications for it could hang communications -
509 manifesting as "Unexpectedly long timeout" messages.
514 Description: Kernel ptllnd lock ordering issue could hang a node.
519 Description: node crash on socket teardown race
522 Frequency : 'lctl peer_list' issued on a mx net
524 Description: Enable lctl's peer_list for MXLND
527 Frequency : after Ptllnd timeouts and portals congestion
529 Description: Credit overflows
530 Details : This was a bug in ptllnd connection establishment. The fix
531 implements better peer stamps to disambiguate connection
532 establishment and ensure both peers enter the credit flow
533 state machine consistently.
538 Description: kptllnd didn't propagate some network errors up to LNET
539 Details : This bug was spotted while investigating 11394. The fix
540 ensures network errors on sends and bulk transfers are
541 propagated to LNET/lustre correctly.
543 Severity : enhancement
545 Description: Fixed console chatter in case of -ETIMEDOUT.
547 Severity : enhancement
549 Description: Added D_NETTRACE for recording network packet history
550 (initially only for ptllnd). Also a separate userspace
551 ptllnd facility to gather history which should really be
552 covered by D_NETTRACE too, if only CDEBUG recorded history in
558 Description: o2iblnd handle early RDMA_CM_EVENT_DISCONNECTED.
559 Details : If the fabric is lossy, an RDMA_CM_EVENT_DISCONNECTED
560 callback can occur before a connection has actually been
561 established. This caused an assertion failure previously.
563 Severity : enhancement
565 Description: Multiple instances for o2iblnd
566 Details : Allow multiple instances of o2iblnd to enable networking over
567 multiple HCAs and routing between them.
571 Description: lnet deadlock in router_checker
572 Details : turned ksnd_connd_lock, ksnd_reaper_lock, and ksock_net_t:ksnd_lock
573 into BH locks to eliminate potential deadlock caused by
574 ksocknal_data_ready() preempting code holding these locks.
578 Description: Millions of failed socklnd connection attempts cause a very slow FS
579 Details : added a new route flag ksnr_scheduled to distinguish from
580 ksnr_connecting, so that a peer connection request is only turned
581 down for race concerns when an active connection to the same peer
582 is under progress (instead of just being scheduled).

604 Details : libcfs created a symlink from /proc/sys/portals to
605 /proc/sys/lnet for backwards compatibility. This is no
606 longer required and makes the Cray portals /proc variables
611 Description: OFED FMR API change
612 Details : This changes parameter usage to reflect a change in
613 ib_fmr_pool_map_phys() between OFED 1.0 and OFED 1.1. Note
614 that FMR support is only used in experimental versions of the
615 o2iblnd - this change does not affect standard usage at all.
617 Severity : enhancement
619 Description: new ko2iblnd module parameter: ib_mtu
620 Details : the default IB MTU of 2048 performs badly on 23108 Tavor
621 HCAs. You can avoid this problem by setting the MTU to 1024
622 using this module parameter.

627 Details : Set the PTL_MD_LOCAL_ALIGN8 option on small message receives.
628 Round up small message size on sends in case this option
629 is not supported. 11620 was a defect in the initial
630 implementation which effectively asserted all peers had to be
631 running the correct protocol version which was fixed by always
632 NAK-ing such requests and handling any misalignments they
637 Description: When kib(nal|lnd)_del_peer() is called upon a peer whose
638 ibp_tx_queue is not empty, kib(nal|lnd)_destroy_peer()'s
639 'LASSERT(list_empty(&peer->ibp_tx_queue))' will fail.
641 Severity : enhancement
643 Description: Patchless ZC(zero copy) socklnd
644 Details : New protocol for socklnd, socklnd can support zero copy without
645 kernel patch, it's compatible with old socklnd. Checksum is
646 moved from tunables to modparams.
650 Description: When ksocknal_del_peer() is called upon a peer whose
651 ksnp_tx_queue is not empty, ksocknal_destroy_peer()'s
652 'LASSERT(list_empty(&peer->ksnp_tx_queue))' will fail.
655 Frequency : when ptlrpc is under heavy use and runs out of request buffer
657 Description: In lnet_match_blocked_msg(), md can be used without holding a
661 Frequency : very rarely
663 Description: If ksocknal_lib_setup_sock() fails, a ref on peer is lost.
664 If connd connects a route which has been closed by
665 ksocknal_shutdown(), ksocknal_create_routes() may create new
666 routes which hold references on the peer, causing shutdown
667 process to wait for peer to disappear forever.
669 Severity : enhancement
671 Description: Dump XT3 portals traces on kptllnd timeout
672 Details : Set the kptllnd module parameter "ptltrace_on_timeout=1" to
673 dump Cray portals debug traces to a file. The kptllnd module
674 parameter "ptltrace_basename", default "/tmp/lnet-ptltrace",
675 is the basename of the dump file.
678 Frequency : infrequent
680 Description: kernel ptllnd fix bug in connection re-establishment
681 Details : Kernel ptllnd could produce protocol errors e.g. illegal
682 matchbits and/or violate the credit flow protocol when trying
683 to re-establish a connection with a peer after an error or
686 Severity : enhancement
688 Description: Allow /proc/sys/lnet/debug to be set symbolically
689 Details : Allow debug and subsystem debug values to be read/set by name
690 in addition to numerically, for ease of use.
693 Frequency : only in configurations with LNET routers
695 Description: routes automatically marked down and recovered
696 Details : In configurations with LNET routers if a router fails routers
697 now actively try to recover routes that are down, unless they
698 are marked down by an administrator.

734 * Configuration change for the XT3
735 The PTLLND is now used to run Lustre over Portals on the XT3.
736 The configure option(s) --with-cray-portals are no longer
737 used. Rather --with-portals=<path-to-portals-includes> is
738 used to enable building on the XT3. In addition to enable
739 XT3 specific features the option --enable-cray-xt3 must be

743 * Portals has been removed, replaced by LNET.
744 LNET is new networking infrastructure for Lustre, it includes a
745 reorganized network configuration mode (see the user
746 documentation for full details) as well as support for routing
747 between different network fabrics. Lustre Networking Devices
748 (LNDS) for the supported network fabrics have also been created
749 for this new infrastructure.

756 Frequency : rare (large Voltaire clusters only)
758 Description: the default number of reserved transmit descriptors was too low
759 for some large clusters
760 Details : As a workaround, the number was increased. A proper fix includes

768 Frequency : occasional (large-scale events, cluster reboot, network failure)
770 Description: too many error messages on console obscure actual problem and
771 can slow down/panic server, or cause recovery to fail repeatedly
772 Details : enable rate-limiting of console error messages, and some messages
773 that were console errors now only go to the kernel log
775 Severity : enhancement
777 Description: add /proc/sys/portals/catastrophe entry which will report if
778 that node has previously LBUGged

795 * Landed portals:b_port_step as follows...
797 - removed CFS_DECL_SPIN*
798 just use 'spinlock_t' and initialise with spin_lock_init()
800 - removed CFS_DECL_MUTEX*
801 just use 'struct semaphore' and initialise with init_mutex()
803 - removed CFS_DECL_RWSEM*
804 just use 'struct rw_semaphore' and initialise with init_rwsem()
