      usbnet: clear OPEN flag in failure path · fb13c47b
      Ming Lei 提交于
      Without clearing OPEN flag in failure path, runtime or system resume
      may submit interrupt/rx URB and start tx queue mistakenly on a
      interface in DOWN state.

      net: qmi_wwan: fix Gobi device probing · b9f90eb2
      Bjørn Mork 提交于
      Ignoring interfaces with additional descriptors is not a reliable
      method for locating the correct interface on Gobi devices.  There
      is at least one device where this method fails:
      https://bbs.archlinux.org/viewtopic.php?id=143506
      
      The result is that the AT command port (interface #2) is hidden
      from qcserial, preventing traditional serial modem usage:
      
      [   15.562552] qmi_wwan 4-1.6:1.0: cdc-wdm0: USB WDM device
      [   15.562691] qmi_wwan 4-1.6:1.0: wwan0: register 'qmi_wwan' at usb-0000:00:1d.0-1.6, Qualcomm Gobi wwan/QMI device, 1e:df:3c:3a:4e:3b
      [   15.563383] qmi_wwan: probe of 4-1.6:1.1 failed with error -22
      [   15.564189] qmi_wwan 4-1.6:1.2: cdc-wdm1: USB WDM device

      [   15.564328] qmi_wwan: probe of 4-1.6:1.3 failed with error -22
      [   15.569376] qcserial 4-1.6:1.1: Qualcomm USB modem converter detected
      [   15.569440] usb 4-1.6: Qualcomm USB modem converter now attached to ttyUSB0
      [   15.570372] qcserial 4-1.6:1.3: Qualcomm USB modem converter detected
      [   15.570430] usb 4-1.6: Qualcomm USB modem converter now attached to ttyUSB1
      
      Use static interface numbers taken from the interface map in
      qcserial for all Gobi devices instead:
      
      	Gobi 1K USB layout:
      	0: serial port (doesn't respond)
      	1: serial port (doesn't respond)
      	2: AT-capable modem port
      	3: QMI/net
      
      	Gobi 2K+ USB layout:
      	0: QMI/net
      	1: DM/DIAG (use libqcdm from ModemManager for communication)
      	2: AT-capable modem port
      	3: NMEA
      
      This should be more reliable over all, and will also prevent the
      noisy "probe failed" messages.  The whitelisting logic is expected
      to be replaced by direct interface number matching in 3.6.

      bnx2x: fix checksum validation · d6cb3e41
      Eric Dumazet 提交于
      bnx2x driver incorrectly sets ip_summed to CHECKSUM_UNNECESSARY on
      encapsulated segments. TCP stack happily accepts frames with bad
      checksums, if they are inside a GRE or IPIP encapsulation.
      
      Our understanding is that if no IP or L4 csum validation was done by the
      hardware, we should leave ip_summed as is (CHECKSUM_NONE), since
      hardware doesn't provide CHECKSUM_COMPLETE support in its cqe.
      
      Then, if IP/L4 checksumming was done by the hardware, set
      CHECKSUM_UNNECESSARY if no error was flagged.

      ath9k: Fix softlockup in AR9485 · bcb7ad7b

      steps to recreate:
      load latest ath9k driver with AR9485
      stop the network-manager and wpa_supplicant
      bring the interface up

      ensure that the PLL-WAR for AR9485/AR9340 is executed only if the STA is
      associated (or) IBSS/AP mode had started beaconing. Ideally this WAR
      is needed to recover from some rare beacon stuck during stress testing.
      Before the STA is associated/IBSS had started beaconing, PLL4(0x1618c)
      always seem to have zero even though we had configured PLL3(0x16188) to
      query about PLL's locking status. When we keep on polling infinitely PLL4's
      8th bit(ie check for PLL locking measurements is done), machine hangs
      due to softlockup.
