      sctp: check duplicate node before inserting a new transport · cd2b7087
      Xin Long authored
      sctp has changed to use rhlist for transport rhashtable since commit
      7fda702f ("sctp: use new rhlist interface on sctp transport
      rhashtable").
      
      But rhltable_insert_key doesn't check the duplicate node when inserting
      a node, unlike rhashtable_lookup_insert_key. It may cause duplicate
      assoc/transport in rhashtable. like:
      
       client (addr A, B)                 server (addr X, Y)
          connect to X           INIT (1)
                              ------------>
          connect to Y           INIT (2)
                              ------------>
                               INIT_ACK (1)
                              <------------
                               INIT_ACK (2)
                              <------------
      
      After sending INIT (2), one transport will be created and hashed into
      rhashtable. But when receiving INIT_ACK (1) and processing the address
      params, another transport will be created and hashed into rhashtable
      with the same addr Y and EP as the last transport. This will confuse
      the assoc/transport's lookup.
      
      This patch is to fix it by returning err if any duplicate node exists
      before inserting it.

      sctp: sctp_transport_dst_check should check if transport pmtu is dst mtu · a4d69a4c
      Xin Long authored
      Now when sending a packet, sctp_transport_dst_check will check if dst
      is obsolete by calling ipv4/ip6_dst_check. But they return obsolete
      only when adding a new cache, after that when the cache's pmtu is
      updated again, it will not trigger transport->dst/pmtu's update.
      
      It can be reproduced by reducing route's pmtu twice. At the 1st time
      client will add a new cache, and transport->pathmtu gets updated as
      sctp_transport_dst_check finds it's obsolete. But at the 2nd time,
      cache's mtu is updated, sctp client will never send out any packet,
      because transport->pmtu has no chance to update.
      
      This patch is to fix this by also checking if transport pmtu is dst
      mtu in sctp_transport_dst_check, so that transport->pmtu can be
      updated on time.

      Merge branch 'sctp-rcv-side-stream-reconf-ssn-reset-req-chunk' · 585396bc

      Xin Long says:
      
      ====================
      sctp: add receiver-side procedures for stream reconf ssn reset request chunk
      
      Patch 3/7 and 4/7 are to implement receiver-side procedures for the
      Outgoing and Incoming SSN Reset Request Parameter described in rfc6525
      section 5.2.2 and 5.2.3
      
      Patch 1/7 and 2/7 are ahead of them to define some apis.
      
      Patch 5/7-7/7 are to add the process of reconf chunk event in rx path.
      
      Note that with this patchset, asoc->reconf_enable has no chance yet to
      be set, until the patch "sctp: add get and set sockopt for reconf_enable"
      is applied in the future. As we can not just enable it when sctp is not
      capable of processing reconf chunk yet.
      
      v1->v2:
        - re-split the patchset and make sure it has no dead codes for review.
        - rename the titles of the commits and improve some changelogs.
        - drop __packed from some structures in patch 1/7.
        - fix some kbuild warnings in patch 3/7 by initializing str_p = NULL.
        - sctp_chunk_lookup_strreset_param changes to return sctp_paramhdr_t *
          and uses sctp_strreset_tsnreq to access request_seq in patch 3/7.
        - use __u<size> in uapi sctp.h in patch 1/7.
        - do str_list endian conversion when generating stream_reset_event in patch
          2/7.
        - remove str_list endian conversion, pass resp_seq param with network endian
          to lookup_strreset_param in 3/7.
        - move str_list endian conversion out of sctp_make_strreset_req, so that
          sctp_make_strreset_req can be used more conveniently to process inreq in
          patch 4/7.
        - remove sctp_merge_reconf_chunk and not support response with multiparam
          in patch 6/7.

      ibmvnic: Make CRQ interrupt tasklet wait for all capabilities crqs · 249168ad
      Thomas Falcon authored
      After sending device capability queries and requests to the vNIC Server,
      an interrupt is triggered and the responses are written to the driver's
      CRQ response buffer. Since the interrupt can be triggered before all
      responses are written and visible to the partition, there is a danger
      that the interrupt handler or tasklet can terminate before all responses
      are read, resulting in a failure to initialize the device.
      
      To avoid this scenario, when capability commands are sent, we set
      a flag that will be checked in the following interrupt tasklet that
      will handle the capability responses from the server. Once all
      responses have been handled, the flag is disabled; and the tasklet
      is allowed to terminate.

      Create a tasklet to process queued commands or messages received from
      firmware instead of processing them in the interrupt handler. Note that
      this handler does not process network traffic, but communications related
      to resource allocation and device settings.

      This RCU warning, however, is suppressed by lockdep_off() in printk().
      lockdep_off() increments the ->lockdep_recursion counter and thus
      disables RCU_LOCKDEP_WARN() and debug_lockdep_rcu_enabled(), which want
      lockdep to be enabled "current->lockdep_recursion == 0".
