Code Issues Releases Wiki Activity

Including fixes from bpf, netfilter and WiFi. 

Current release - regressions:
 
   - bpf: fix a kernel crash for the riscv 64 JIT
 
   - bnxt_en: fix memory leak in bnxt_hwrm_get_rings()
 
   - revert "net: macsec: use skb_ensure_writable_head_tail to expand the skb"
 
 Previous releases - regressions:
 
   - core: fix removing a namespace with conflicting altnames
 
   - tc/flower: fix chain template offload memory leak
 
   - tcp:
     - make sure init the accept_queue's spinlocks once
     - fix autocork on CPUs with weak memory model
 
   - udp: fix busy polling
 
   - mlx5e:
     - fix out-of-bound read in port timestamping
     - fix peer flow lists corruption
 
   - iwlwifi: fix a memory corruption
 
 Previous releases - always broken:
 
   - netfilter:
     - nft_chain_filter: handle NETDEV_UNREGISTER for inet/ingress basechain
     - nft_limit: reject configurations that cause integer overflow
 
   - bpf: fix bpf_xdp_adjust_tail() with XSK zero-copy mbuf, avoiding
     a NULL pointer dereference upon shrinking
 
   - llc: make llc_ui_sendmsg() more robust against bonding changes
 
   - smc: fix illegal rmb_desc access in SMC-D connection dump
 
   - dpll: fix pin dump crash for rebound module
 
   - bnxt_en: fix possible crash after creating sw mqprio TCs
 
   - hv_netvsc: calculate correct ring size when PAGE_SIZE is not 4 Kbytes
 
 Misc:
 
   - several self-tests fixes for better integration with the netdev CI
 
   - added several missing modules descriptions

Pull networking fixes from Paolo Abeni:
 "Including fixes from bpf, netfilter and WiFi.

  Jakub is doing a lot of work to include the self-tests in our CI, as a
  result a significant amount of self-tests related fixes is flowing in
  (and will likely continue in the next few weeks).

  Current release - regressions:

   - bpf: fix a kernel crash for the riscv 64 JIT
