The USB interface between the host and the bluetooth adapter used for SCO packets uses an USB isochronous endpoint with a fragmentation scheme that does not tolerate errors. Except USB isochronous transfers do not provide a reliable stream with guaranteed delivery. (There is no retry on error, see USB spec v2.0 5.6 and 8.5.5.) To fragment a packet, the bluetooth HCI simply splits it in parts and transfer them as-is. The receiver is expected to reconstruct the packet by assuming the first fragment contains the header and parsing its size field. There is no error detection either. If a fragment is lost, the end result is that the kernel is no longer synchronized and will pass malformed data to the upper layers, since it has no way to tell if the first fragment is an actual first fragment or a continuation fragment. Resynchronization can only happen by luck and requires an unbounded amount of time. The typical symptom for a HSP/HFP bluetooth headset is that the microphone stops working and dmesg contains piles of rate-limited "Bluetooth: hci0: SCO packet for unknown connection handle XXXX" errors for an indeterminate amount of time, until the kernel accidentally resynchronize. A workaround is to ask the upper layer to prevalidate the first fragment header. This is not possible with user channels so this workaround is disabled in this case. This problem is the most severe when using an ath3k adapter on an i.MX 6 board, where packet loss occur regularly, possibly because it is an USB1 device connected on an USB2 hub and this is a special case requiring split transactions.

Recently, a customer reported that from their container whose net namespace is different to the host's init_net, they can't set the container's net.sctp.rto_max to any value smaller than init_net.sctp.rto_min. For instance, Host: sudo sysctl net.sctp.rto_min net.sctp.rto_min = 1000 Container: echo 100 > /mnt/proc-net/sctp/rto_min echo 400 > /mnt/proc-net/sctp/rto_max echo: write error: Invalid argument This is caused by the check made from this'commit 4f3fdf3b ("sctp: add check rto_min and rto_max in sysctl")' When validating the input value, it's always referring the boundary value set for the init_net namespace. Having container's rto_max smaller than host's init_net.sctp.rto_min does make sense. Consider that the rto between two containers on the same host is very likely smaller than it for two hosts. So to fix this problem, as suggested by Marcelo, this patch makes the extra pointers of rto_min, rto_max, pf_retrans, and ps_retrans point to the corresponding variables from the newly created net namespace while the new net namespace is being registered in sctp_sysctl_net_register. Fixes: 4f3fdf3b ("sctp: add check rto_min and rto_max in sysctl") Reviewed-by:

TCAN4X5X_ERROR_STATUS is not a status register that needs clearing during interrupt handling. Instead this is a masking register that masks error interrupts. Writing TCAN4X5X_CLEAR_ALL_INT to this register effectively masks everything. Rename the register and mask all error interrupts only once by writing to the register in tcan4x5x_init.

The TXFQS register is read first to check if the fifo is full and then immediately again to get the putidx. This is unnecessary and adds significant overhead if read requests are done over a slow bus, for example SPI with tcan4x5x. Add a variable to store the value of the register.

Vincent Mailhol <mailhol.vincent@wanadoo.fr> says: The goal of this series is to report the firmware version, the bootloader version and the hardware revision of ETAS ES58x devices. These are already reported in the kernel log but this isn't best practice. Remove the kernel log and instead export all these through devlink. The devlink core automatically exports the firmware and the bootloader version to ethtool, so no need to implement the ethtool_ops::get_drvinfo() callback anymore. Patch one and two implement the core support for devlink (at device level) and devlink port (at the network interface level). Patch three export usb_cache_string() and patch four add a new info attribute to devlink.h. Both are prerequisites for patch five. Patch five is the actual goal: it parses the product information from a custom usb string returned by the device and expose them through devlink. Patch six removes the product information from the kernel log. Finally, patch seven add a devlink documentation page with list all the information attributes reported by the driver. * Sample outputs following this series * | $ devlink dev info | usb/1-9:1.1: | serial_number 0108954 | versions: | fixed: | board.rev B012/000 | running: | fw 04.00.01 | fw.bootloader 02.00.00 | $ devlink port show can0 | usb/1-9:1.1/0: type eth netdev can0 flavour physical port 0 splittable false | $ ethtool -i can0 | driver: etas_es58x | version: 6.1.0-rc7+ | firmware-version: 04.00.01 02.00.00 | expansion-rom-version: | bus-info: 1-9:1.1 | supports-statistics: no | supports-test: no | supports-eeprom-access: no | supports-register-dump: no | supports-priv-flags: no * Changelog * v4 -> v5: https://lore.kernel.org/all/20221130174658.29282-1-mailhol.vincent@wanadoo.fr * [PATH 2/7] add devlink port support. This extends devlink to the network interface. * thanks to devlink port, 'ethtool -i' is now able to retrieve the firmware version from devlink. No need to implement the ethtool_ops::get_drvinfo() callback anymore: remove one patch from the series. * [PATCH 4/7] A new patch to add a new info attribute for the bootloader version in devlink.h. This patch was initially sent as a standalone patch here: https://lore.kernel.org/netdev/20221129031406.3849872-1-mailhol.vincent@wanadoo.fr Merging it to this series so that it is both added and used at the same time. * [PATCH 5/7] use the newly info attribute defined in patch 4/7 to report the bootloader version instead of the custom string "bl". * [PATCH 5/7] because the series does not implement ethtool_ops::get_drvinfo() anymore, the two helper functions es58x_sw_version_is_set() and es58x_hw_revision_is_set() are only used in devlink.c. Move them from es58x_core.h to es58x_devlink.c. * [PATCH 5/7] small rework of the helper function es58x_hw_revision_is_set(): it is OK to only check the letter (if the letter is '\0', it will not be possible to print the next numbers). * [PATCH 5/7 and 6/7] add reviewed-by Andrew Lunn tag. * [PATCH 7/7] Now, 'ethtool -i' reports both the firmware version and the bootloader version (this is how the core export the information from devlink to ethtool). Update the documentation to reflect this fact. * Reoder the patches. v3 -> v4: https://lore.kernel.org/all/20221126162211.93322-1-mailhol.vincent@wanadoo.fr * major rework to use devlink instead of sysfs following Andrew's comment. * split the series in 6 patches. * [PATCH 1/6] add Acked-by: Greg Kroah-Hartman v2 -> v3: https://lore.kernel.org/all/20221113040108.68249-1-mailhol.vincent@wanadoo.fr * patch 2/3: do not spam the kernel log anymore with the product number. Instead parse the product information string, extract the firmware version, the bootloadar version and the hardware revision and export them through sysfs. * patch 2/3: rework the parsing in order not to need additional fields in struct es58x_parameters. * patch 3/3: only populate ethtool_drvinfo::fw_version because since commit edaf5df2 ("ethtool: ethtool_get_drvinfo: populate drvinfo fields even if callback exits"), there is no need to populate ethtool_drvinfo::driver and ethtool_drvinfo::bus_info in the driver. v1 -> v2: https://lore.kernel.org/all/20221104171604.24052-1-mailhol.vincent@wanadoo.fr * was a single patch.

As discussed in [1], abbreviating the bootloader to "bl" might not be well understood. Instead, a bootloader technically being a firmware, name it "fw.bootloader".

The CANFD block on the RZ/Five SoC is identical to one found on the RZ/G2UL SoC. "renesas,r9a07g043-canfd" compatible string will be used on the RZ/Five SoC so to make this clear, update the comment to include RZ/Five SoC. No driver changes are required as generic compatible string "renesas,rzg2l-canfd" will be used as a fallback on RZ/Five SoC. Signed-off-by:
