Merge tag 'linux-can-next-for-5.5-20191111' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next Marc Kleine-Budde says: ==================== pull-request: can-next 2019-10-07 this is a pull request for net-next/master consisting of 32 patches. The first patch is by Gustavo A. R. Silva and removes unused code in the generic CAN infrastructure. The next three patches target the mcp251x driver. The one by Andy Shevchenko removes the legacy platform data support from the driver. The other two are by Timo Schlüßler and reset the device only when needed, to prevent glitches on the output when GPIO support is added. I'm contributing two patches fixing checkpatch warnings in the c_can_platform and peak_canfd driver. Stephane Grosjean's patch for the peak_canfd driver adds hw timestamps support in rx skbs. The next three patches target the xilinx_can driver. One patch by me to fix checkpatch warnings, one patch by Anssi Hannula to avoid non requested bus error frames, and a patch by YueHaibing that switches the driver to devm_platform_ioremap_resource(). Pankaj Sharma contributes two patches for the m_can driver, the first one adds support for one shot mode, the other support for handling arbitration errors. Followed by four patches by YueHaibing, switching the grcan, ifi, rcar, and sun4i drivers to devm_platform_ioremap_resource() I'm contributing cleanup patches for the rx-offload helper, while Joakim Zhang's patch prepares the rx-offload helper for CAN-FD support. The rx offload users flexcan and ti_hecc are converted accordingly. The remaining twelve patches target the flexcan driver. First Joakim Zhang switches the driver to devm_platform_ioremap_resource(). The remaining eleven patch are by me and clean up the abstract the access of the iflag1 and iflag2 register both for RX and TX mailboxes. This is a preparation for the upcoming CAN-FD support. ==================== Signed-off-by:

The sfc driver can drop packets processed with XDP, notably when running out of buffer space on XDP_TX, or returning an unknown XDP action. This increments the rx_xdp_bad_drops ethtool counter. Call trace_xdp_exception everywhere rx_xdp_bad_drops is incremented, except for fragmented RX packets as the XDP program hasn't run yet. This allows it to easily be monitored from userspace. This mirrors the behavior of other drivers. Signed-off-by:

Aya Levin says: ==================== Update devlink binary output This series changes the devlink binary interface: -The first patch forces binary values to be enclosed in an array. In addition, devlink_fmsg_binary_pair_put breaks the binary value into chunks to comply with devlink's restriction for value length. -The second patch removes redundant code and uses the fixed devlink interface (devlink_fmsg_binary_pair_put). -The third patch make self test to use the updated devlink interface. -The fourth, adds a verification of dumping a very large binary content. This test verifies breaking the data into chunks in a valid JSON output. Series was generated against net-next commit: ca22d697 Merge branch 'stmmac-next' ==================== Signed-off-by:

Ido Schimmel says: ==================== mlxsw: Add extended ACK for EMADs Shalom says: Ethernet Management Datagrams (EMADs) are Ethernet packets sent between the driver and device's firmware. They are used to pass various configurations to the device, but also to get events (e.g., port up) from it. After the Ethernet header, these packets are built in a TLV format. Up until now, whenever the driver issued an erroneous register access it only got an error code indicating a bad parameter was used. This patch set adds a new TLV (string TLV) that can be used by the firmware to encode a 128 character string describing the error. The new TLV is allocated by the driver and set to zeros. In case of error, the driver will check the length of the string in the response and report it using devlink hwerr tracepoint. Example: $ perf record -a -q -e devlink:devlink_hwerr & $ pkill -2 perf $ perf script -F trace:event,trace | grep hwerr devlink:devlink_hwerr: bus_name=pci dev_name=0000:03:00.0 driver_name=mlxsw_spectrum err=7 (tid=9913892d00001593,reg_id=8018(rauhtd)) bad parameter (inside er_rauhtd_write_query(), num_rec=32 is over the maximum number of records supported) Patch #1 parses the offsets of the different TLVs in incoming EMADs and stores them in the skb's control block. This makes it easier to later add new TLVs. Patches #2-#3 remove deprecated TLVs and add string TLV definition. Patches #4-#7 gradually add support for the new string TLV. v2: * Use existing devlink hwerr tracepoint to report the error string, instead of printing it to kernel log ==================== Signed-off-by: -

Shalom Toledo authored
Until now the code assumes a fixed structure which makes it difficult to support EMADs with and without new TLVs. Make it more generic by parsing the TLVs when the EMADs are received and store the offset to the different TLVs in the control block. Using these offsets to extract information from the EMADs without relying on a specific structure. Signed-off-by:

Russell King says: ==================== sfp: Allow slow to initialise GPON modules to work Some GPON modules take longer than the SFF MSA specified time to initialise and respond to transactions on the I2C bus for either both 0x50 and 0x51, or 0x51 bus addresses. Technically these modules are non-compliant with the SFP Multi-Source Agreement, they have been around for some time, so are difficult to just ignore. Most of the patch series is restructuring the code to make it more readable, and split various things into separate functions. We split the three state machines into three separate functions, and re-arrange them to start probing the module as soon as a module has been detected (without waiting for the network device.) We try to read the module's EEPROM, retrying quickly for the first second, and then once every five seconds for about a minute until we have read the EEPROM. So that the kernel isn't entirely silent, we print a message indicating that we're waiting for the module to respond after the first second, or when all retries have expired. Once the module ID has been read, we kick off a delayed work queue which attempts to register the hwmon, retrying for up to a minute if the monitoring parameters are unreadable; this allows us to proceed with module initialisation independently of the hwmon state. With high-power modules, we wait for the netdev to be attached before switching the module power mode, and retry this in a similar way to before until we have successfully read and written the EEPROM at 0x51. We also move the handling of the TX_DISABLE signal entirely to the main state machine, and avoid probing any on-board PHY while TX_FAULT is set. ==================== Signed-off-by: -
Russell King authored
When a module is inserted, we attempt to read read the ID from address 0x50. Once we are able to read the ID, we immediately attempt to initialise the hwmon support by reading from address 0x51. If this fails, then we fall into error state, and assume that the module is not usable. Modules such as the ALCATELLUCENT 3FE46541AA use a real EEPROM for I2C address 0x50, which responds immediately. However, address 0x51 is an emulated, which only becomes available once the on-board firmware has booted. This prompts us to fall into the error state. Since the module may be usable without diagnostics, arrange for the hwmon probe independent of the rest of the SFP itself, retrying every 5s for up to about 60s for the monitoring to become available, and print an error message if it doesn't become available.
