2023-10-25mptcp: add a new sysctl for make after break timeoutPaolo Abeni1-0/+11
The MPTCP protocol allows sockets with no alive subflows to stay in ESTABLISHED status for and user-defined timeout, to allow for later subflows creation. Currently such timeout is constant - TCP_TIMEWAIT_LEN. Let the user-space configure them via a newly added sysctl, to better cope with busy servers and simplify (make them faster) the relevant pktdrill tests. Note that the new know does not apply to orphaned MPTCP socket waiting for the data_fin handshake completion: they always wait TCP_TIMEWAIT_LEN.

2023-10-25dt-bindings: marvell: Add Marvell MV88E6060 DSA schemaLinus Walleij1-0/+88
The Marvell MV88E6060 is one of the oldest DSA switches from Marvell, and it has DT bindings used in the wild. Let's define them properly. It is different enough from the rest of the MV88E6xxx switches that it deserves its own binding.

2023-10-20netlink: add variable-length / auto integersJakub Kicinski1-2/+16
We currently push everyone to use padding to align 64b values in netlink. Un-padded nla_put_u64() doesn't even exist any more. The story behind this possibly start with this thread: https://lore.kernel.org/netdev/20121204.130914.1457976839967676240.davem@davemloft.net/ where DaveM was concerned about the alignment of a structure containing 64b stats. If user space tries to access such struct directly: struct some_stats *stats = nla_data(attr); printf("A: %llu", stats->a); lack of alignment may become problematic for some architectures. These days we most often put every single member in a separate attribute, meaning that the code above would use a helper like nla_get_u64(), which can deal with alignment internally. Even for arches which don't have good unaligned access - access aligned to 4B should be pretty efficient. Kernel and well known libraries deal with unaligned input already. Padded 64b is quite space-inefficient (64b + pad means at worst 16B per attr vs 32b which takes 8B). It is also more typing: if (nla_put_u64_pad(rsp, NETDEV_A_SOMETHING_SOMETHING, value, NETDEV_A_SOMETHING_PAD)) Create a new attribute type which will use 32 bits at netlink level if value is small enough (probably most of the time?), and (4B-aligned) 64 bits otherwise. Kernel API is just: if (nla_put_uint(rsp, NETDEV_A_SOMETHING_SOMETHING, value)) Calling this new type "just" sint / uint with no specific size will hopefully also make people more comfortable with using it. Currently telling people "don't use u8, you may need the bits, and netlink will round up to 4B, anyway" is the #1 comment we give to newcomers. In terms of netlink layout it looks like this: 0 4 8 12 16 32b: [nlattr][ u32 ] 64b: [ pad ][nlattr][ u64 ] uint(32) [nlattr][ u32 ] uint(64) [nlattr][ u64 ] Signed-off-by: Jakub Kicinski <kuba@kernel.org> Acked-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: David S.

The support is less than trivial, because we try to keep struct nla_policy tiny the min/max members it holds in place are s16. Meaning we can only express checks in range of s16.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2023-10-10 1) Adham Faris, Increase max supported channels number to 256 2) Leon Romanovsky, Allow IPsec soft/hard limits in bytes 3) Shay Drory, Replace global mlx5_intf_lock with HCA devcom component lock 4) Wei Zhang, Optimize SF creation flow During SF creation, HCA state gets changed from INVALID to IN_USE step by step. Accordingly, FW sends vhca event to driver to inform about this state change asynchronously. Each vhca event is critical because all related SW/FW operations are triggered by it. Currently there is only a single mlx5 general event handler which not only handles vhca event but many other events. This incurs huge bottleneck because all events are forced to be handled in serial manner. Moreover, all SFs share same table_lock which inevitably impacts each other when they are created in parallel. This series will solve this issue by: 1. A dedicated vhca event handler is introduced to eliminate the mutual impact with other mlx5 events. 2. Max FW threads work queues are employed in the vhca event handler to fully utilize FW capability. 3. Redesign SF active work logic to completely remove table_lock. With above optimization, SF creation time is reduced by 25%, i.e. from 80s to 60s when creating 100 SFs. Patches summary: Patch 1 - implement dedicated vhca event handler with max FW cmd threads of work queues. Patch 2 - remove table_lock by redesigning SF active work logic. * tag 'mlx5-updates-2023-10-10' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: net/mlx5e: Allow IPsec soft/hard limits in bytes net/mlx5e: Increase max supported channels number to 256 net/mlx5e: Preparations for supporting larger number of channels net/mlx5e: Refactor mlx5e_rss_init() and mlx5e_rss_free() API's net/mlx5e: Refactor mlx5e_rss_set_rxfh() and mlx5e_rss_get_rxfh() net/mlx5e: Refactor rx_res_init() and rx_res_free() APIs net/mlx5e: Use PTR_ERR_OR_ZERO() to simplify code net/mlx5: Use PTR_ERR_OR_ZERO() to simplify code net/mlx5: fix config name in Kconfig parameter documentation net/mlx5: Remove unused declaration net/mlx5: Replace global mlx5_intf_lock with HCA devcom component lock net/mlx5: Refactor LAG peer device lookout bus logic to mlx5 devcom net/mlx5: Avoid false positive lockdep warning by adding lock_class_key net/mlx5: Redesign SF active work to remove table_lock net/mlx5: Parallelize vhca event handling ==================== Link: https://lore.kernel.org/r/20231014171908.290428-1-saeed@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2023-10-17tcp: Set pingpong threshold via sysctlHaiyang Zhang1-0/+13
TCP pingpong threshold is 1 by default. But some applications, like SQL DB may prefer a higher pingpong threshold to activate delayed acks in quick ack mode for better performance. The pingpong threshold and related code were changed to 3 in the year 2019 in: commit 4a41f453bedf ("tcp: change pingpong threshold to 3") And reverted to 1 in the year 2022 in: commit 4d8f24eeedc5 ("Revert "tcp: change pingpong threshold to 3"") There is no single value that fits all applications. Add net.ipv4.tcp_pingpong_thresh sysctl tunable, so it can be tuned for optimal performance based on the application needs.
