This is an updated patch series for the Kvaser CAN/USB devices: 1- Extra patches are now added to the series. Most importantly patch #1 which fixes a critical `sleep in atomic context' bug in the current upstream driver. Patch #2 fixes a corruption in the kernel logs, also affecting current upstream driver. Patch #4 was originally USBCan-II only, but since it's a generic fix, it's now retrofitted to the Leaf-only upstream driver first. 2- The series has been re-organized so that patches #1 -> #4 inclusive can go to linux-can/origin, while the rest can move to -next. 3- There are some important updates regarding the USBCan-II error counters, and how really erratic their heaviour is. All the new details are covered at the bottom of this URL: http://article.gmane.org/gmane.linux.can/7481 4- Attached below is the new candump traces. Now `back-to-error-active' states appear _if_ the hardware was kind enough and decreased the error counters appropriately. The earlier code did not recognize the error counters going down, thus the `back-to-error-active' transitions did not appear. ########################################################### * Bus-off scenario (with transitions active -> passive -> back-to-active): (000.000000) can0 20000080 [8] 00 00 00 00 00 00 30 00 ERRORFRAME bus-error error-counter-tx-rx{{48}{0}} (000.000011) can0 20000084 [8] 00 20 00 00 00 00 88 00 ERRORFRAME controller-problem{tx-error-passive} bus-error error-counter-tx-rx{{136}{0}} (000.000001) can0 20000080 [8] 00 00 00 00 00 00 88 00 ERRORFRAME bus-error error-counter-tx-rx{{136}{0}} (000.000987) can0 20000080 [8] 00 00 00 00 00 00 98 00 ERRORFRAME bus-error error-counter-tx-rx{{152}{0}} (000.002011) can0 20000084 [8] 00 40 00 00 00 00 30 00 ERRORFRAME controller-problem{back-to-error-active} bus-error error-counter-tx-rx{{48}{0}} (000.000004) can0 20000084 [8] 00 20 00 00 00 00 78 00 ERRORFRAME controller-problem{tx-error-passive} bus-error error-counter-tx-rx{{120}{0}} (000.000002) can0 20000080 [8] 00 00 00 00 00 00 88 00 ERRORFRAME bus-error error-counter-tx-rx{{136}{0}} (000.000005) can0 20000080 [8] 00 00 00 00 00 00 90 00 ERRORFRAME bus-error error-counter-tx-rx{{144}{0}} (000.000002) can0 20000080 [8] 00 00 00 00 00 00 98 00 ERRORFRAME bus-error error-counter-tx-rx{{152}{0}} (000.000001) can0 20000080 [8] 00 00 00 00 00 00 A0 00 ERRORFRAME bus-error error-counter-tx-rx{{160}{0}} (000.000966) can0 20000080 [8] 00 00 00 00 00 00 A8 00 ERRORFRAME bus-error error-counter-tx-rx{{168}{0}} (000.002998) can0 20000084 [8] 00 40 00 00 00 00 30 00 ERRORFRAME controller-problem{back-to-error-active} bus-error error-counter-tx-rx{{48}{0}} (000.000004) can0 20000084 [8] 00 20 00 00 00 00 80 00 ERRORFRAME controller-problem{tx-error-passive} bus-error error-counter-tx-rx{{128}{0}} (000.000002) can0 20000080 [8] 00 00 00 00 00 00 88 00 ERRORFRAME bus-error error-counter-tx-rx{{136}{0}} (001.031035) can0 200000C0 [8] 00 00 00 00 00 00 00 29 ERRORFRAME bus-off bus-error error-counter-tx-rx{{0}{41}} ########################################################### Regular sending, unpluggng CAN connector, then plugging again: (with transitions active -> warning -> passive) [ As stated earlier, the counters don't get decreased upon CAN replug, even if they were constantly polled. ] (000.011001) can0 2A1 [1] E5 (000.010001) can0 50E [8] E6 05 00 00 00 00 00 00 (000.009999) can0 009 [1] E7 (000.011000) can0 6E2 [8] E8 05 00 00 00 00 00 00 (000.009999) can0 314 [2] E9 05 (000.010001) can0 708 [6] EA 05 00 00 00 00 (000.010991) can0 20000080 [8] 00 00 00 00 00 00 00 09 ERRORFRAME bus-error error-counter-tx-rx{{0}{9}} (000.000002) can0 20000080 [8] 00 00 00 00 00 00 00 0A ERRORFRAME bus-error error-counter-tx-rx{{0}{10}} (000.000007) can0 20000080 [8] 00 00 00 00 00 00 00 2E ERRORFRAME bus-error error-counter-tx-rx{{0}{46}} (000.000003) can0 20000080 [8] 00 00 00 00 00 00 00 37 ERRORFRAME bus-error error-counter-tx-rx{{0}{55}} (000.000002) can0 20000080 [8] 00 00 00 00 00 00 00 40 ERRORFRAME bus-error error-counter-tx-rx{{0}{64}} (000.000993) can0 20000080 [8] 00 00 00 00 00 00 00 49 ERRORFRAME bus-error error-counter-tx-rx{{0}{73}} (000.000002) can0 20000080 [8] 00 00 00 00 00 00 00 52 ERRORFRAME bus-error error-counter-tx-rx{{0}{82}} (000.000001) can0 20000080 [8] 00 00 00 00 00 00 00 5B ERRORFRAME bus-error error-counter-tx-rx{{0}{91}} (000.000028) can0 20000084 [8] 00 04 00 00 00 00 00 6C ERRORFRAME controller-problem{rx-error-warning} bus-error error-counter-tx-rx{{0}{108}} (000.000955) can0 20000080 [8] 00 00 00 00 00 00 00 7F ERRORFRAME bus-error error-counter-tx-rx{{0}{127}} (000.000008) can0 20000084 [8] 00 10 00 00 00 00 00 87 ERRORFRAME controller-problem{rx-error-passive} bus-error error-counter-tx-rx{{0}{135}} (000.000001) can0 20000080 [8] 00 00 00 00 00 00 00 87 ERRORFRAME bus-error error-counter-tx-rx{{0}{135}} (000.000004) can0 20000080 [8] 00 00 00 00 00 00 00 87 ERRORFRAME bus-error error-counter-tx-rx{{0}{135}} ((( Then a continous flood, exactly similar to the above packet, appears ))) (000.500004) can0 2ED [4] EB 05 00 00 (000.000006) can0 0DD [5] EC 05 00 00 00 (000.000002) can0 1D3 [1] ED (000.000988) can0 20D [8] EE 05 00 00 00 00 00 00 (000.000006) can0 04B [8] EF 05 00 00 00 00 00 00 (000.000002) can0 320 [8] F0 05 00 00 00 00 00 00 (000.000002) can0 023 [8] F1 05 00 00 00 00 00 00 (000.000989) can0 21D [8] F2 05 00 00 00 00 00 00 (000.000005) can0 17D [8] F3 05 00 00 00 00 00 00 (000.000002) can0 6DC [8] F4 05 00 00 00 00 00 00 (000.000993) can0 62D [8] F5 05 00 00 00 00 00 00 (000.000006) can0 18B [6] F6 05 00 00 00 00 (000.000001) can0 7EB [8] F7 05 00 00 00 00 00 00 (000.000001) can0 014 [8] F8 05 00 00 00 00 00 00 (000.000994) can0 52F [8] F9 05 00 00 00 00 00 00 -- Regards, Darwish
