Code Issues Releases Wiki Activity

Networking fixes for 5.10-rc2. 

Current release regressions:
 
  - r8169: fix forced threading conflicting with other shared
    interrupts; we tried to fix the use of raise_softirq_irqoff
    from an IRQ handler on RT by forcing hard irqs, but this
    driver shares legacy PCI IRQs so drop the _irqoff() instead
 
  - tipc: fix memory leak caused by a recent syzbot report fix
    to tipc_buf_append()
 
 Current release - bugs in new features:
 
  - devlink: Unlock on error in dumpit() and fix some error codes
 
  - net/smc: fix null pointer dereference in smc_listen_decline()
 
 Previous release - regressions:
 
  - tcp: Prevent low rmem stalls with SO_RCVLOWAT.
 
  - net: protect tcf_block_unbind with block lock
 
  - ibmveth: Fix use of ibmveth in a bridge; the self-imposed filtering
    to only send legal frames to the hypervisor was too strict
 
  - net: hns3: Clear the CMDQ registers before unmapping BAR region;
    incorrect cleanup order was leading to a crash
 
  - bnxt_en - handful of fixes to fixes:
     - Send HWRM_FUNC_RESET fw command unconditionally, even
       if there are PCIe errors being reported
     - Check abort error state in bnxt_open_nic().
     - Invoke cancel_delayed_work_sync() for PFs also.
     - Fix regression in workqueue cleanup logic in bnxt_remove_one().
 
  - mlxsw: Only advertise link modes supported by both driver
    and device, after removal of 56G support from the driver
    56G was not cleared from advertised modes
 
  - net/smc: fix suppressed return code
 
 Previous release - always broken:
 
  - netem: fix zero division in tabledist, caused by integer overflow
 
  - bnxt_en: Re-write PCI BARs after PCI fatal error.
 
  - cxgb4: set up filter action after rewrites
 
  - net: ipa: command payloads already mapped
 
 Misc:
 
  - s390/ism: fix incorrect system EID, it's okay to change since
    it was added in current release
 
  - vsock: use ns_capable_noaudit() on socket create to suppress
    false positive audit messages
