In genl_bind(), currently genl_lock and write cb_lock are taken for iteration of genl_fam_idr and processing of static values stored in struct genl_family. Take just read cb_lock for this task as it is sufficient to guard the idr and the struct against concurrent genl_register/unregister_family() calls. This will allow to run genl command processing in genl_rcv() and mnl_socket_setsockopt(.., NETLINK_ADD_MEMBERSHIP, ..) in parallel. Reported-by:

Since the probe defaults all interfaces to the highest speed possible (10GBASE-X in mv88e6393x) before the phy mode configuration from the devicetree is considered it is currently impossible to use port 0 in RGMII mode. This change will allow RGMII modes to be configurable for port 0 enabling port 0 to be configured as RGMII as well as serial depending on configuration. Signed-off-by:

The Lenovo OneLink+ Dock contains an RTL8153 controller that behaves as a broken CDC device by default. Add the custom Lenovo PID to the r8152 driver to support it properly. Also, systems compatible with this dock provide a BIOS option to enable MAC address passthrough (as per Lenovo document "ThinkPad Docking Solutions 2017"). Add the custom PID to the MAC passthrough list too. Tested on a ThinkPad 13 1st gen with the expected results: passthrough disabled: Invalid header when reading pass-thru MAC addr passthrough enabled: Using pass-thru MAC addr XX:XX:XX:XX:XX:XX Signed-off-by:

Maksym Glubokiy says: ==================== net: prestera: matchall features This patch series extracts matchall rules management out of SPAN API implementation and adds 2 features on top of that: - support for egress traffic (mirred egress action) - proper rule priorities management between matchall and flower ==================== Signed-off-by: -
Maksym Glubokiy authored
matchall rules can be added only to chain 0 and their priorities have limitations: - new matchall ingress rule's priority must be higher (lower value) than any existing flower rule; - new matchall egress rule's priority must be lower (higher value) than any existing flower rule. The opposite works for flower rule adding: - new flower ingress rule's priority must be lower (higher value) than any existing matchall rule; - new flower egress rule's priority must be higher (lower value) than any existing matchall rule. This is a hardware limitation and thus must be properly handled in driver by reporting errors to the user when newly added rule has such a priority that cannot be installed into the hardware. To achieve this, the driver must maintain both min/max matchall priorities for every flower block when user adds/deletes a matchall rule, as well as both min/max flower priorities for chain 0 for every adding/deletion of flower rules for chain 0.

This commit adds more clarity to handling of TC_CLSMATCHALL_REPLACE and TC_CLSMATCHALL_DESTROY events by calling newly added *_mall_*() handlers instead of directly calling SPAN API. This also extracts matchall rules management out of SPAN API since SPAN is a hardware module which is used to implement 'matchall egress mirred' action only. Signed-off-by:

Use try_cmpxchg instead of cmpxchg (*ptr, old, new) == old in napi_if_scheduled_mark_missed. x86 CMPXCHG instruction returns success in ZF flag, so this change saves a compare after cmpxchg (and related move instruction in front of cmpxchg). Also, try_cmpxchg implicitly assigns old *ptr value to "old" when cmpxchg fails, enabling further code simplifications.

Jiri Pirko says: ==================== net: devlink: sync flash and dev info commands Purpose of this patchset is to introduce consistency between two devlink commands: devlink dev info Shows versions of running default flash target and components. devlink dev flash Flashes default flash target or component name (if specified on cmdline). Currently it is up to the driver what versions to expose and what flash update component names to accept. This is inconsistent. Thankfully, only netdevsim currently using components so it is still time to sanitize this. This patchset makes sure, that devlink.c calls into driver for component flash update only in case the driver exposes the same version name. Example: $ devlink dev info netdevsim/netdevsim10: driver netdevsim versions: running: fw.mgmt 10.20.30 stored: fw.mgmt 10.20.30 $ devlink dev flash netdevsim/netdevsim10 file somefile.bin [fw.mgmt] Preparing to flash [fw.mgmt] Flashing 100% [fw.mgmt] Flash select [fw.mgmt] Flashing done $ devlink dev flash netdevsim/netdevsim10 file somefile.bin component fw.mgmt [fw.mgmt] Preparing to flash [fw.mgmt] Flashing 100% [fw.mgmt] Flash select [fw.mgmt] Flashing done $ devlink dev flash netdevsim/netdevsim10 file somefile.bin component dummy Error: selected component is not supported by this device. ==================== Link: https://lore.kernel.org/r/20220824122011.1204330-1-jiri@resnulli.usSigned-off-by: -

Limit the acceptance of component name passed to cmd_flash_update() to match one of the versions returned by info_get(), marked by version type. This makes things clearer and enforces 1:1 mapping between exposed version and accepted flash component. Check VERSION_TYPE_COMPONENT version type during cmd_flash_update() execution by calling info_get() with different "req" context. That causes info_get() to lookup the component name instead of filling-up the netlink message. Remove "UPDATE_COMPONENT" flag which becomes used. Signed-off-by:

Jiri Pirko authored
Whenever the driver is called by his info_get() op, it may put multiple version names and values to the netlink message. Extend by additional helper devlink_info_version_running/stored_put_ext() that allows to specify a version type that indicates when particular version name represents a flash component. This is going to be used in follow-up patch calling info_get() during flash update command checking if version with this the version type exists. Signed-off-by:

When the xrx200_hw_receive() function returns -ENOMEM, the NAPI poll function immediately returns an error. This is incorrect for two reasons: * the function terminates without enabling interrupts or scheduling NAPI, * the error code (-ENOMEM) is returned instead of the number of received packets.

This is a follow-up to the discussion in [0]. It seems to me that at least the IP version used on Amlogic SoC's sometimes has a problem if register MAC_CTRL_REG is written whilst the chip is still processing a previous write. But that's just a guess. Adding a delay between two writes to this register helps, but we can also simply omit the offending second write. This patch uses the second approach and is based on a suggestion from Qi Duan. Benefit of this approach is that we can save few register writes, also on not affected chip versions.
