      tipc: fix access of released memory · e0e853ac
      Jon Maloy authored
      When the function tipc_group_filter_msg() finds that a member event
      indicates that the member is leaving the group, it first deletes the
      member instance, and then purges the message queue being handled
      by the call. But the message queue is an aggregated field in the
      just deleted item, leading the purge call to access freed memory.
      
      We fix this by swapping the order of the two actions.

      mlxsw: spectrum: Do not try to create non-existing ports during unsplit · bf4e9f24
      Ido Schimmel authored
      On some systems, when we unsplit a port we need to re-create two ports
      instead. On other systems, only one needs to be re-created.
      
      Do not try to create a port if during driver initialization it was
      assigned a negative module number, which is invalid.
      
      This avoids the following error during unsplit:
      [  941.012478] mlxsw_spectrum 0000:01:00.0: Port 43: Failed to map module
      
      The error is harmless and caused by the fact that a local port is
      already mapped to module 0.

      mac80211: properly free requested-but-not-started TX agg sessions · 33ddd81e
      Johannes Berg authored
      When deleting a station or otherwise tearing down all aggregation
      sessions, make sure to delete requested but not yet started ones,
      to avoid the following scenario:
      
       * session is requested, added to tid_start_tx[]
       * ieee80211_ba_session_work() runs, gets past BLOCK_BA check
       * ieee80211_sta_tear_down_BA_sessions() runs, locks &sta->ampdu_mlme.mtx,
         e.g. while deleting the station - deleting all active sessions
       * ieee80211_ba_session_work() continues since tear down flushes it, and
         calls ieee80211_tx_ba_session_handle_start() for the new session, arms
         the timer for it
       * station deletion continues to __cleanup_single_sta() and frees the
         session struct, while the timer is armed

      cfg80211: initialize regulatory keys/database later · d7be102f
      Johannes Berg authored
      When cfg80211 is built as a module, everything is fine, and we
      can keep the code as is; in fact, we have to, because there can
      only be a single module_init().
      
      When cfg80211 is built-in, however, it needs to initialize
      before drivers (device_initcall/module_init), and thus used to
      be at subsys_initcall(). I'd moved it to fs_initcall() earlier,
      where it can remain. However, this is still too early because at
      that point the key infrastructure hasn't been initialized yet,
      so X.509 certificates can't be parsed yet.
      
      To work around this problem, load the regdb keys only later in
      a late_initcall(), at which point the necessary infrastructure
      has been initialized.

      For mesh, this is simply wrong - there's no SSID, only the

      For (P2P) client, it's wrong, because it exposes an internal
      value that's only used when certain APIs are used.
      For AP, it's actually the only correct case, so leave that.

      Linus Torvalds authored
      Pull ntb updates from Jon Mason:
       "Support for the switchtec ntb and related changes. Also, a couple of
        bug fixes"
      
      [ The timing isn't great. I had asked people to send me pull requests
        before my family vacation, and this code has not even been in
        linux-next as far as I can tell. But Logan Gunthorpe pleaded for its
        inclusion because the Switchtec driver has apparently been around for
        a while, just never in linux-next - Linus ]

      net: ena: fix race condition between device reset and link up setup · d18e4f68
      Netanel Belgazal authored
      In rare cases, ena driver would reset and re-start the device,
      for example, in case of misbehaving application that causes
      transmit timeout
      
      The first step in the reset procedure is to stop the Tx traffic by
      calling ena_carrier_off().
      
      After the driver have just started the device reset procedure, device
      happens to send an asynchronous notification (via AENQ) to the driver
      than there was a link change (to link-up state).
      This link change is mapped to a call to netif_carrier_on() which
      re-activates the Tx queues, violating the assumption of no tx traffic
      until device reset is completed, as the reset task might still be in
      the process of queues initialization, leading to an access to
      uninitialized memory.
