2019-06-09nfp: ensure skb network header is set for packet redirectJohn Hurley
Packets received at the NFP driver may be redirected to egress of another netdev (e.g. in the case of OvS internal ports). On the egress path, some processes, like TC egress hooks, may expect the network header offset field in the skb to be correctly set. If this is not the case there is potential for abnormal behaviour and even the triggering of BUG() calls. Set the skb network header field before the mac header pull when doing a packet redirect.

2019-06-09net: phy: rename Asix Electronics PHY driverMichael Schmitz
[Resent to net instead of net-next - may clash with Anders Roxell's patch series addressing duplicate module names] Commit 31dd83b96641 ("net-next: phy: new Asix Electronics PHY driver") introduced a new PHY driver drivers/net/phy/asix.c that causes a module name conflict with a pre-existiting driver (drivers/net/usb/asix.c). The PHY driver is used by the X-Surf 100 ethernet card driver, and loaded by that driver via its PHY ID. A rename of the driver looks unproblematic. Rename PHY driver to ax88796b.c in order to resolve name conflict.

2019-06-09Input: iqs5xx - get axis info before calling input_mt_init_slots()Jeff LaBundy
Calling input_mt_init_slots() copies ABS_MT_POSITION_X to ABS_X and so on, but doing so before calling touchscreen_parse_properties() leaves ABS_X min = max = 0 which may prompt an X server to ignore the device. To solve this problem, wait to call input_mt_init_slots() until all absolute axis information has been resolved (whether that's through device tree via touchscreen_parse_properties() or from reading from the device directly).

2019-06-08i2c: xiic: Add max_read_len quirkRobert Hancock
This driver does not support reading more than 255 bytes at once because the register for storing the number of bytes to read is only 8 bits. Add a max_read_len quirk to enforce this. This was found when using this driver with the SFP driver, which was previously reading all 256 bytes in the SFP EEPROM in one transaction. This caused a bunch of hard-to-debug errors in the xiic driver since the driver/logic was treating the number of bytes to read as zero. Rejecting transactions that aren't supported at least allows the problem to be diagnosed more easily.

2019-06-08gpio: pca953x: hack to fix 24 bit gpio expandersH. Nikolaus Schaller
24 bit expanders use REG_ADDR_AI in combination with register addressing. This conflicts with regmap which takes this bit as part of the register number, i.e. a second cache entry is defined for accessed with REG_ADDR_AI being set although on the chip it is the same register as with REG_ADDR_AI being cleared. The problem was introduced by commit b32cecb46bdc ("gpio: pca953x: Extract the register address mangling to single function") but only became visible by commit 8b9f9d4dc511 ("regmap: verify if register is writeable before writing operations") because before, the regmap size was effectively ignored and pca953x_writeable_register() did know to ignore REG_ADDR_AI. Still, there were two separate cache entries created. Since the use of REG_ADDR_AI seems to be static we can work around this issue by simply increasing the size of the regmap to cover the "virtual" registers with REG_ADDR_AI being set. This only means that half of the regmap buffer will be unused. Reported-by: H. Nikolaus Schaller <hns@goldelico.com> Suggested-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: H.

2019-06-07net/mlx5e: Replace reciprocal_scale in TX select queue functionShay Agroskin
The TX queue index returned by the fallback function ranges between [0,NUM CHANNELS - 1] if QoS isn't set and [0, (NUM CHANNELS)*(NUM TCs) -1] otherwise. Our HW uses different TC mapping than the fallback function (which is denoted as 'up', user priority) so we only need to extract a channel number out of the returned value. Since (NUM CHANNELS)*(NUM TCs) is a relatively small number, using reciprocal scale almost always returns zero. We instead access the 'txq2sq' table to extract the sq (and with it the channel number) associated with the tx queue, thus getting a more evenly distributed channel number. Perf: Rx/Tx side with Intel(R) Xeon(R) Silver 4108 CPU @ 1.80GHz and ConnectX-5. Used 'iperf' UDP traffic, 10 threads, and priority 5. Before: 0.566Mpps After: 2.37Mpps As expected, releasing the existing bottleneck of steering all traffic to TX queue zero significantly improves transmission rates.

2019-06-07net/mlx5: Update pci error handler entries and command translationEdward Srouji
Add missing entries for create/destroy UCTX and UMEM commands. This could get us wrong "unknown FW command" error in flows where we unbind the device or reset the driver. Also the translation of these commands from opcodes to string was missing.

2019-06-07RAS/CEC: Convert the timer callback to a workqueueCong Wang
cec_timer_fn() is a timer callback which reads ce_arr.array[] and updates its decay values. However, it runs in interrupt context and the mutex protection the CEC uses for that array, is inadequate. Convert the used timer to a workqueue to keep the tasks the CEC performs preemptible and thus low-prio.

2019-06-07RAS/CEC: Fix binary search functionBorislav Petkov
Switch to using Donald Knuth's binary search algorithm (The Art of Computer Programming, vol. 3, section 6.2.1). This should've been done from the very beginning but the author must've been smoking something very potent at the time. The problem with the current one was that it would return the wrong element index in certain situations: https://lkml.kernel.org/r/CAM_iQpVd02zkVJ846cj-Fg1yUNuz6tY5q1Vpj4LrXmE06dPYYg@mail.gmail.com and the noodling code after the loop was fishy at best. So switch to using Knuth's binary search. The final result is much cleaner and straightforward.

2019-06-07can: flexcan: Remove unneeded registration messageFabio Estevam
Currently the following message is observed when the flexcan driver is probed: flexcan 2090000.flexcan: device registered (reg_base=(ptrval), irq=23) The reason for printing 'ptrval' is explained at Documentation/core-api/printk-formats.rst: "Pointers printed without a specifier extension (i.e unadorned %p) are hashed to prevent leaking information about the kernel memory layout. This has the added benefit of providing a unique identifier. On 64-bit machines the first 32 bits are zeroed. The kernel will print ``(ptrval)`` until it gathers enough entropy." Instead of passing %pK, which can print the correct address, simply remove the entire message as it is not really that useful.

2019-06-07can: m_can: implement errata "Needless activation of MRAF irq"Eugen Hristev
During frame reception while the MCAN is in Error Passive state and the Receive Error Counter has thevalue MCAN_ECR.REC = 127, it may happen that MCAN_IR.MRAF is set although there was no Message RAM access failure. If MCAN_IR.MRAF is enabled, an interrupt to the Host CPU is generated. Work around: The Message RAM Access Failure interrupt routine needs to check whether MCAN_ECR.RP = '1' and MCAN_ECR.REC = '127'. In this case, reset MCAN_IR.MRAF. No further action is required. This affects versions older than 3.2.0 Errata explained on Sama5d2 SoC which includes this hardware block: http://ww1.microchip.com/downloads/en/DeviceDoc/SAMA5D2-Family-Silicon-Errata-and-Data-Sheet-Clarification-DS80000803B.pdf chapter 6.2 Reproducibility: If 2 devices with m_can are connected back to back, configuring different bitrate on them will lead to interrupt storm on the receiving side, with error "Message RAM access failure occurred". Another way is to have a bad hardware connection. Bad wire connection can lead to this issue as well. This patch fixes the issue according to provided workaround.

2019-06-07can: flexcan: fix timeout when set small bitrateJoakim Zhang
Current we can meet timeout issue when setting a small bitrate like 10000 as follows on i.MX6UL EVK board (ipg clock = 66MHZ, per clock = 30MHZ): | root@imx6ul7d:~# ip link set can0 up type can bitrate 10000 A link change request failed with some changes committed already. Interface can0 may have been left with an inconsistent configuration, please check. | RTNETLINK answers: Connection timed out It is caused by calling of flexcan_chip_unfreeze() timeout. Originally the code is using usleep_range(10, 20) for unfreeze operation, but the patch (8badd65 can: flexcan: avoid calling usleep_range from interrupt context) changed it into udelay(10) which is only a half delay of before, there're also some other delay changes. After double to FLEXCAN_TIMEOUT_US to 100 can fix the issue. Meanwhile, Rasmus Villemoes reported that even with a timeout of 100, flexcan_probe() fails on the MPC8309, which requires a value of at least 140 to work reliably. 250 works for everyone.
