      net: tls: fix memory leaks and freeing skbs
      
      This series fixes two memory issues and a stack overflow.
      First two patches are fairly simple leaks.  Third patch
      partially reverts an optimization made to the strparser
      which causes creation of skb->frag_list->skb->frag_list...
      chains of 100s of skbs, leading to recursive kfree_skb()
      filling up the kernel stack.

      net: strparser: partially revert "strparser: Call skb_unclone conditionally" · 4a9c2e37
      Jakub Kicinski authored
      This reverts the first part of commit 4e485d06 ("strparser: Call
      skb_unclone conditionally").  To build a message with multiple
      fragments we need our own root of frag_list.  We can't simply
      use the frag_list of orig_skb, because it will lead to linking
      all orig_skbs together creating very long frag chains, and causing
      stack overflow on kfree_skb() (which is called recursively on
      the frag_lists).

      net/tls: don't leak partially sent record in device mode · 35b71a34
      Jakub Kicinski authored
      David reports that tls triggers warnings related to
      sk->sk_forward_alloc not being zero at destruction time:

      When sender fills up the write buffer and dies from
      SIGPIPE.  This is due to the device implementation
      not cleaning up the partially_sent_record.
      
      This is because commit a42055e8 ("net/tls: Add support for async encryption of records for performance")
      moved the partial record cleanup to the SW-only path.

      ibmvnic: Fix netdev features settings on reset
      
      In its current state, a driver reset clobbers any feature settings
      a user may have toggled and will disable GRO as it is not explicitly

      user settings after a reset. If the underlying carrier changes, however,
      the driver will disable features unsupported by the new carrier.

      ibmvnic: Fix netdev feature clobbering during a reset · dde746a3
      Thomas Falcon authored
      While determining offload capabilities of backing hardware during
      a device reset, the driver is clobbering current feature settings.
      Update hw_features on reset instead of features unless a feature
      is enabled that is no longer supported on the current backing device.
      Also enable features that were not supported prior to the reset but
      were previously enabled or requested by the user.
      
      This can occur if the reset is the result of a carrier change, such
      as a device failover or partition migration.

      ====================
      mlxsw: Various fixes
      
      This patchset contains various small fixes for mlxsw.
      
      Patch #1 fixes a warning generated by switchdev core when the driver
      fails to insert an MDB entry in the commit phase.
      
      Patches #2-#4 fix a warning in check_flush_dependency() that can be
      triggered when a work item in a WQ_MEM_RECLAIM workqueue tries to flush
      a non-WQ_MEM_RECLAIM workqueue.
      
      It seems that the semantics of the WQ_MEM_RECLAIM flag are not very
      clear [1] and that various patches have been sent to remove it from
      various workqueues throughout the kernel [2][3][4] in order to silence
      the warning.
      
      These patches do the same for the workqueues created by mlxsw that
      probably should not have been created with this flag in the first place.
      
      Patch #5 fixes a regression where an IP address cannot be assigned to a
      VRF upper due to erroneous MAC validation check. Patch #6 adds a test
      case.
      
      Patch #7 adjusts Spectrum-2 shared buffer configuration to be compatible
      with Spectrum-1. The problem and fix are described in detail in the
      commit message.
      
      Please consider patches #1-#5 for 5.0.y. I verified they apply cleanly.

      mlxsw: spectrum_buffers: Add a multicast pool for Spectrum-2 · d5949d92
      Ido Schimmel authored
      In Spectrum-1, when a multicast packet is admitted to the shared buffer
      it increases the quotas of all the ports and {port, TC} to which it is
      forwarded to.
      
      The above means that multicast packets are accounted multiple times in
      the shared buffer and can therefore cause the associated shared buffer
      pool to fill up very quickly.
      
      To work around this issue, commit e83c045e ("mlxsw:
      spectrum_buffers: Configure MC pool") added a dedicated multicast pool
      in which multicast packets are accounted.
      
      The issue is not present in Spectrum-2, but in order to be backward
      compatible with Spectrum-1, its default behavior is to allow a multicast
      packet to increase multiple egress quotas instead of one.
      
      Until the new (non-backward compatible) mode is supported, configure a
      dedicated multicast pool as in Spectrum-1.

      ====================
      Various fixes:
       * iTXQ fixes from Felix
       * tracing fix - increase message length
       * fix SW_CRYPTO_CONTROL enforcement
       * WMM rule handling for regdomain intersection
       * max_interfaces in hwsim - reported by syzbot
       * clear private data in some more commands
       * a clang compiler warning fix
      
      I added a patch with two new (unused) macros for
      rate-limited printing to simplify getting the users
      into the tree.

      mac80211: Honor SW_CRYPTO_CONTROL for unicast keys in AP VLAN mode · 78ad2341
      Alexander Wetzel authored
      Restore SW_CRYPTO_CONTROL operation on AP_VLAN interfaces for unicast
      keys, the original override was intended to be done for group keys as
      those are treated specially by mac80211 and would always have been
      rejected.
      
      Now the situation is that AP_VLAN support must be enabled by the driver
      if it can support it (meaning it can support software crypto GTK TX).
      
      Thus, also simplify the code - if we get here with AP_VLAN and non-
      pairwise key, software crypto must be used (driver doesn't know about
      the interface) and can be used (driver must've advertised AP_VLAN if
      it also uses SW_CRYPTO_CONTROL).

      ====================
      bnxt_en: 2 bug fixes.
      
      The first patch prevents possible driver crash if we get a bad RX index
      from the hardware.  The second patch resets the device when the hardware
      reports buffer error to recover from the error.
      
      Please queue these for -stable also.  Thanks.
