netdev: add per-queue statistics JIRA: https://issues.redhat.com/browse/RHEL-57771 commit ab63a2387cb906d43b72a8effb611bbaecb2d0cd Author: Jakub Kicinski <kuba@kernel.org> Date: Wed Mar 6 11:55:07 2024 -0800 netdev: add per-queue statistics The ethtool-nl family does a good job exposing various protocol related and IEEE/IETF statistics which used to get dumped under ethtool -S, with creative names. Queue stats don't have a netlink API, yet, and remain a lion's share of ethtool -S output for new drivers. Not only is that bad because the names differ driver to driver but it's also bug-prone. Intuitively drivers try to report only the stats for active queues, but querying ethtool stats involves multiple system calls, and the number of stats is read separately from the stats themselves. Worse still when user space asks for values of the stats, it doesn't inform the kernel how big the buffer is. If number of stats increases in the meantime kernel will overflow user buffer. Add a netlink API for dumping queue stats. Queue information is exposed via the netdev-genl family, so add the stats there. Support per-queue and sum-for-device dumps. Latter will be useful when subsequent patches add more interesting common stats than just bytes and packets. The API does not currently distinguish between HW and SW stats. The expectation is that the source of the stats will either not matter much (good packets) or be obvious (skb alloc errors).

netdev-genl: create a simple family for netdev stuff Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2178930 Conflicts: - include/linux/netdevice.h: Context difference in includes due to missing 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs with IPv6 addresses, performance of changing link state, attaching a VRF, changing an IPv6 address, etc. go down dramtically.") - net/core/Makefile: Context difference due to missing 2c193f2cb110 ("net: kunit: add a test for dev_addr_lists") commit d3d854fd6a1d97157f790604e07f6386e8df8fe4 Author: Jakub Kicinski <kuba@kernel.org> Date: Wed Feb 1 11:24:17 2023 +0100 netdev-genl: create a simple family for netdev stuff Add a Netlink spec-compatible family for netdevs. This is a very simple implementation without much thought going into it. It allows us to reap all the benefits of Netlink specs, one can use the generic client to issue the commands: $ ./cli.py --spec netdev.yaml --dump dev_get [{'ifindex': 1, 'xdp-features': set()}, {'ifindex': 2, 'xdp-features': {'basic', 'ndo-xmit', 'redirect'}}, {'ifindex': 3, 'xdp-features': {'rx-sg'}}] the generic python library does not have flags-by-name support, yet, but we also don't have to carry strings in the messages, as user space can get the names from the spec.
