2024-10-15Merge branch 'replace-call_rcu-by-kfree_rcu-for-simple-kmem_cache_free-callback'Jakub Kicinski5-39/+6
Julia Lawall says: ==================== replace call_rcu by kfree_rcu for simple kmem_cache_free callback Since SLOB was removed and since commit 6c6c47b063b5 ("mm, slab: call kvfree_rcu_barrier() from kmem_cache_destroy()"), it is not necessary to use call_rcu when the callback only performs kmem_cache_free. Use kfree_rcu() directly. The changes were done using the following Coccinelle semantic patch.

2024-10-15Merge branch 'net-af_packet-allow-joining-a-fanout-when-link-is-down'Jakub Kicinski2-7/+80
Gur Stavi says: ==================== net: af_packet: allow joining a fanout when link is down PACKET socket can retain its fanout membership through link down and up and leave a fanout while closed regardless of link state. However, socket was forbidden from joining a fanout while it was not RUNNING. This scenario was identified while studying DPDK pmd_af_packet_drv. Since sockets are only created during initialization, there is no reason to fail the initialization if a single link is temporarily down. This patch allows PACKET socket to join a fanout while not RUNNING. Selftest psock_fanout is extended to test this "fanout while link down" scenario. Selftest psock_fanout is also extended to test fanout create/join by socket that did not bind or specified a protocol, which carries an implicit bind. v3: https://lore.kernel.org/cover.1728555449.git.gur.stavi@huawei.com v2: https://lore.kernel.org/cover.1728382839.git.gur.stavi@huawei.com v1: https://lore.kernel.org/cover.1728303615.git.gur.stavi@huawei.com ==================== Link: https://patch.msgid.link/cover.1728802323.git.gur.stavi@huawei.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2024-10-15af_packet: allow fanout_add when socket is not RUNNINGGur Stavi1-4/+5
PACKET socket can retain its fanout membership through link down and up and leave a fanout while closed regardless of link state. However, socket was forbidden from joining a fanout while it was not RUNNING. This patch allows PACKET socket to join fanout while not RUNNING. Socket can be RUNNING if it has a specified protocol. Either directly from packet_create (being implicitly bound to any interface) or following a successful bind. Socket RUNNING state is switched off if it is bound to an interface that went down. Instead of the test for RUNNING, this patch adds a test that socket can become RUNNING.

2024-10-15dt-bindings: net: tja11xx: add "nxp,rmii-refclk-out" propertyWei Fang1-0/+16
Per the RMII specification, the REF_CLK is sourced from MAC to PHY or from an external source. But for TJA11xx PHYs, they support to output a 50MHz RMII reference clock on REF_CLK pin. Previously the "nxp,rmii-refclk-in" was added to indicate that in RMII mode, if this property present, REF_CLK is input to the PHY, otherwise it is output. This seems inappropriate now. Because according to the RMII specification, the REF_CLK is originally input, so there is no need to add an additional "nxp,rmii-refclk-in" property to declare that REF_CLK is input. Unfortunately, because the "nxp,rmii-refclk-in" property has been added for a while, and we cannot confirm which DTS use the TJA1100 and TJA1101 PHYs, changing it to switch polarity will cause an ABI break. But fortunately, this property is only valid for TJA1100 and TJA1101. For TJA1103/TJA1104/TJA1120/TJA1121 PHYs, this property is invalid because they use the nxp-c45-tja11xx driver, which is a different driver from TJA1100/TJA1101. Therefore, for PHYs using nxp-c45-tja11xx driver, add "nxp,rmii-refclk-out" property to support outputting RMII reference clock on REF_CLK pin.

Joe Damato says: ==================== Add support for per-NAPI config via netlink Greetings: Welcome to v6. Minor changes from v5 [1], please see changelog below. There were no explicit comments from reviewers on the call outs in my v5, so I'm retaining them from my previous cover letter just in case :) A few important call outs for reviewers: 1. This revision seems to work (see below for a full walk through). I think this is the behavior we talked about, but please let me know if a use case is missing. 2. Re a previous point made by Stanislav regarding "taking over a NAPI ID" when the channel count changes: mlx5 seems to call napi_disable followed by netif_napi_del for the old queues and then calls napi_enable for the new ones. In this RFC, the NAPI ID generation is deferred to napi_enable. This means we won't end up with two of the same NAPI IDs added to the hash at the same time. Can we assume all drivers will napi_disable the old queues before napi_enable the new ones? - If yes: we might not need to worry about a NAPI ID takeover function. - If no: I'll need to make a change so that the NAPI ID generation is deferred only for drivers which have opted into the config space via calls to netif_napi_add_config 3. I made the decision to remove the WARN_ON_ONCE that (I think?) Jakub previously suggested in alloc_netdev_mqs (WARN_ON_ONCE(txqs != rxqs);) because this was triggering on every kernel boot with my mlx5 NIC. 4. I left the "maxqs = max(txqs, rxqs);" in alloc_netdev_mqs despite thinking this is a bit strange. I think it's strange that we might be short some number of NAPI configs, but it seems like most people are in favor of this approach, so I've left it. I'd appreciate thoughts from reviewers on the above items, if at all possible. Now, on to the implementation. Firstly, this implementation moves certain settings to napi_struct so that they are "per-NAPI", while taking care to respect existing sysfs parameters which are interface wide and affect all NAPIs: - NAPI ID - gro_flush_timeout - defer_hard_irqs Furthermore: - NAPI ID generation and addition to the hash is now deferred to napi_enable, instead of during netif_napi_add - NAPIs are removed from the hash during napi_disable, instead of netif_napi_del. - An array of "struct napi_config" is allocated in net_device. IMPORTANT: The above changes affect all network drivers. Optionally, drivers may opt-in to using their config space by calling netif_napi_add_config instead of netif_napi_add. If a driver does this, the NAPI being added is linked with an allocated "struct napi_config" and the per-NAPI settings (including NAPI ID) are persisted even as hardware queues are destroyed and recreated. To help illustrate how this would end up working, I've added patches for 3 drivers, of which I have access to only 1: - mlx5 which is the basis of the examples below - mlx4 which has TX only NAPIs, just to highlight that case. I have only compile tested this patch; I don't have this hardware. - bnxt which I have only compiled tested. I don't have this hardware. NOTE: I only tested this on mlx5; I have no access to the other hardware for which I provided patches. Hopefully other folks can help test :) Here's how it works when I test it on my mlx5 system: $ ethtool -l eth4 | grep Combined | tail -1 Combined: 2 First, output the current NAPI settings: $ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml \ --dump napi-get --json='{"ifindex": 7}' [{'defer-hard-irqs': 0, 'gro-flush-timeout': 0, 'id': 345, 'ifindex': 7, 'irq': 527}, {'defer-hard-irqs': 0, 'gro-flush-timeout': 0, 'id': 344, 'ifindex': 7, 'irq': 327}] Now, set the global sysfs parameters: $ sudo bash -c 'echo 20000 >/sys/class/net/eth4/gro_flush_timeout' $ sudo

gro_flush_timeout of 0: $ sudo ./tools/net/ynl/cli.py \ --spec Documentation/netlink/specs/netdev.yaml \ --do napi-set --json='{"id": 345, "gro-flush-timeout": 0}' None Check that NAPI ID 345 has a

'irq': 527}, {'defer-hard-irqs': 100, 'gro-flush-timeout': 20000, 'id': 344, 'ifindex': 7, 'irq': 327}] Change the queue count, ensuring that NAPI ID 345 retains its settings: $ sudo ethtool -L eth4 combined 4 Check that the new queues have the system wide settings but that NAPI ID 345 remains unchanged: $ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml \ --dump napi-get

queue count below where NAPI ID 345 is indexed: $ sudo ethtool -L eth4 combined 1 Check the output: $ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml \ --dump napi-get

sudo ethtool -L eth4 combined 2 $ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml \ --dump napi-get --json='{"ifindex": 7}' [{'defer-hard-irqs': 111, 'gro-flush-timeout': 0,

NAPIs but that NAPI ID 345 is unchanged: $ sudo ethtool -L eth4 combined 8 $ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml \ --dump napi-get --json='{"ifindex": 7}' [...]

100, 'gro-flush-timeout': 20000, 'id': 344, 'ifindex': 7, 'irq': 327}] Last, but not least, let's try writing the sysfs parameters to ensure all NAPIs are rewritten: $ sudo bash -c 'echo 33333 >/sys/class/net/eth4/gro_flush_timeout' $ sudo bash -c 'echo 222 >/sys/class/net/eth4/napi_defer_hard_irqs' Check that worked: $ ./tools/net/ynl/cli.py --spec Documentation/netlink/specs/netdev.yaml \

2024-10-15net: napi: Add napi_configJoe Damato4-10/+119
Add a persistent NAPI config area for NAPI configuration to the core. Drivers opt-in to setting the persistent config for a NAPI by passing an index when calling netif_napi_add_config. napi_config is allocated in alloc_netdev_mqs, freed in free_netdev (after the NAPIs are deleted). Drivers which call netif_napi_add_config will have persistent per-NAPI settings: NAPI IDs, gro_flush_timeout, and defer_hard_irq settings. Per-NAPI settings are saved in napi_disable and restored in napi_enable.
