      Pull ucounts fixes from Eric Biederman:
       "There has been one very hard to track down bug in the ucount code that
        we have been tracking since roughly v5.14 was released. Alex managed
        to find a reliable reproducer a few days ago and then I was able to
        instrument the code and figure out what the issue was.
      
        It turns out the sigqueue_alloc single atomic operation optimization
        did not play nicely with ucounts multiple level rlimits. It turned out
        that either sigqueue_alloc or sigqueue_free could be operating on
        multiple levels and trigger the conditions for the optimization on
        more than one level at the same time.
      
        To deal with that situation I have introduced inc_rlimit_get_ucounts
        and dec_rlimit_put_ucounts that just focuses on the optimization and
        the rlimit and ucount changes.
      
        While looking into the big bug I found I couple of other little issues
        so I am including those fixes here as well.
      
        When I have time I would very much like to dig into process ownership
        of the shared signal queue and see if we could pick a single owner for
        the entire queue so that all of the rlimits can count to that owner.
        That should entirely remove the need to call get_ucounts and
        put_ucounts in sigqueue_alloc and sigqueue_free. It is difficult
        because Linux unlike POSIX supports setuid that works on a single
        thread"

      net: enetc: make sure all traffic classes can send large frames · e378f496
      Vladimir Oltean authored
      The enetc driver does not implement .ndo_change_mtu, instead it
      configures the MAC register field PTC{Traffic Class}MSDUR[MAXSDU]
      statically to a large value during probe time.
      
      The driver used to configure only the max SDU for traffic class 0, and
      that was fine while the driver could only use traffic class 0. But with
      the introduction of mqprio, sending a large frame into any other TC than
      0 is broken.
      
      This patch fixes that by replicating per traffic class the static
      configuration done in enetc_configure_port_mac().

      sfc: Export fibre-specific supported link modes · c62041c5
      Erik Ekman authored
      The 1/10GbaseT modes were set up for cards with SFP+ cages in
      3497ed8c ("sfc: report supported link speeds on SFP connections").
      10GbaseT was likely used since no 10G fibre mode existed.
      
      The missing fibre modes for 1/10G were added to ethtool.h in 5711a982
      ("net: ethtool: add support for 1000BaseX and missing 10G link modes")
      shortly thereafter.
      
      The user guide available at https://support-nic.xilinx.com/wp/drivers
      lists support for the following cable and transceiver types in section 2.9:
      - QSFP28 100G Direct Attach Cables
      - QSFP28 100G SR Optical Transceivers (with SR4 modules listed)
      - SFP28 25G Direct Attach Cables
      - SFP28 25G SR Optical Transceivers
      - QSFP+ 40G Direct Attach Cables
      - QSFP+ 40G Active Optical Cables
      - QSFP+ 40G SR4 Optical Transceivers
      - QSFP+ to SFP+ Breakout Direct Attach Cables
      - QSFP+ to SFP+ Breakout Active Optical Cables
      - SFP+ 10G Direct Attach Cables
      - SFP+ 10G SR Optical Transceivers
      - SFP+ 10G LR Optical Transceivers
      - SFP 1000BASE‐T Transceivers
      - 1G Optical Transceivers
      (From user guide issue 28. Issue 16 which also includes older cards like
      SFN5xxx/SFN6xxx has matching lists for 1/10/40G transceiver types.)
      
      Regarding SFP+ 10GBASE‐T transceivers the latest guide says:
      "Solarflare adapters do not support 10GBASE‐T transceiver modules."
      
      Tested using SFN5122F-R7 (with 2 SFP+ ports). Supported link modes do not change
      depending on module used (tested with 1000BASE-T, 1000BASE-BX10, 10GBASE-LR).

      ====================
      Netfilter/IPVS fixes for net
      
      The following patchset contains Netfilter fixes for net:
      
      1) Crash due to missing initialization of timer data in
         xt_IDLETIMER, from Juhee Kang.
      
      2) NF_CONNTRACK_SECMARK should be bool in Kconfig, from Vegard Nossum.
      
      3) Skip netdev events on netns removal, from Florian Westphal.
      
      4) Add testcase to show port shadowing via UDP, also from Florian.
      
      5) Remove pr_debug() code in ip6t_rt, this fixes a crash due to
         unsafe access to non-linear skbuff, from Xin Long.
      
      6) Make net/ipv4/vs/debug_level read-only from non-init netns,
         from Antoine Tenart.
      
      7) Remove bogus invocation to bash in selftests/netfilter/nft_flowtable.sh
         also from Florian.
