2023-06-25netlink: specs: add display-hint to schema definitionsDonald Hunter3-1/+22
Add a display-hint property to the netlink schema that is for providing optional hints to generic netlink clients about how to display attribute values. A display-hint on an attribute definition is intended for letting a client such as ynl know that, for example, a u32 should be rendered as an ipv4 address. The display-hint enumeration includes a small number of networking domain-specific value types.

2023-06-17tcp: enforce receive buffer memory limits by allowing the tcp window to shrinkmfreemon@cloudflare.com1-0/+15
Under certain circumstances, the tcp receive buffer memory limit set by autotuning (sk_rcvbuf) is increased due to incoming data packets as a result of the window not closing when it should be. This can result in the receive buffer growing all the way up to tcp_rmem[2], even for tcp sessions with a low BDP. To reproduce: Connect a TCP session with the receiver doing nothing and the sender sending small packets (an infinite loop of socket send() with 4 bytes of payload with a sleep of 1 ms in between each send()). This will cause the tcp receive buffer to grow all the way up to tcp_rmem[2]. As a result, a host can have individual tcp sessions with receive buffers of size tcp_rmem[2], and the host itself can reach tcp_mem limits, causing the host to go into tcp memory pressure mode. The fundamental issue is the relationship between the granularity of the window scaling factor and the number of byte ACKed back to the sender. This problem has previously been identified in RFC 7323, appendix F [1]. The Linux kernel currently adheres to never shrinking the window. In addition to the overallocation of memory mentioned above, the current behavior is functionally incorrect, because once tcp_rmem[2] is reached when no remediations remain (i.e. tcp collapse fails to free up any more memory and there are no packets to prune from the out-of-order queue), the receiver will drop in-window packets resulting in retransmissions and an eventual timeout of the tcp session. A receive buffer full condition should instead result in a zero window and an indefinite wait. In practice, this problem is largely hidden for most flows. It is not applicable to mice flows. Elephant flows can send data fast enough to "overrun" the sk_rcvbuf limit (in a single ACK), triggering a zero window. But this problem does show up for other types of flows. Examples are websockets and other type of flows that send small amounts of data spaced apart slightly in time. In these cases, we directly encounter the problem described in [1]. RFC 7323, section 2.4 [2], says there are instances when a retracted window can be offered, and that TCP implementations MUST ensure that they handle a shrinking window, as specified in RFC 1122, section 4.2.2.16 [3]. All prior RFCs on the topic of tcp window management have made clear that sender must accept a shrunk window from the receiver, including RFC 793 [4] and RFC 1323 [5]. This patch implements the functionality to shrink the tcp window when necessary to keep the right edge within the memory limit by autotuning (sk_rcvbuf). This new functionality is enabled with the new sysctl: net.ipv4.tcp_shrink_window Additional information can be found at: https://blog.cloudflare.com/unbounded-memory-usage-by-tcp-for-receive-buffers-and-how-we-fixed-it/ [1] https://www.rfc-editor.org/rfc/rfc7323#appendix-F [2] https://www.rfc-editor.org/rfc/rfc7323#section-2.4 [3] https://www.rfc-editor.org/rfc/rfc1122#page-91 [4] https://www.rfc-editor.org/rfc/rfc793 [5] https://www.rfc-editor.org/rfc/rfc1323 Signed-off-by: Mike Freemon <mfreemon@cloudflare.com> Reviewed-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2023-06-16dt-bindings: net: wireless: ath10k: add ieee80211-freq-limit propertyChristian Lamparter1-0/+4
This is an existing optional property that ieee80211.yaml/cfg80211 provides. It's useful to further restrict supported frequencies for a specified device through device-tree. For testing the addition, I added the ieee80211-freq-limit property with values from an OpenMesh A62 device. This is because the OpenMesh A62 has "special filters in front of the RX+TX paths to the 5GHz PHYs. These filtered channel can in theory still be used by the hardware but the signal strength is reduced so much that it makes no sense." The driver supported this since ~2018 by commit 34d5629d2ca8 ("ath10k: limit available channels via DT ieee80211-freq-limit") Link: https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=e3b8ae2b09e137ce2eae33551923daf302293a0c Signed-off-by: Christian Lamparter <chunkeey@gmail.com> Acked-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Signed-off-by: Kalle Valo <quic_kvalo@quicinc.com> Link: https://lore.kernel.org/r/c33c928b7c6c9bb4e7abe84eb8df9f440add275b.1686486464.git.chunkeey@gmail.com
2023-06-16net: ena: Add dynamic recycling mechanism for rx buffersDavid Arinzon1-0/+32
The current implementation allocates page-sized rx buffers. As traffic may consist of different types and sizes of packets, in various cases, buffers are not fully used. This change (Dynamic RX Buffers - DRB) uses part of the allocated rx page needed for the incoming packet, and returns the rest of the unused page to be used again as an rx buffer for future packets. A threshold of 2K for unused space has been set in order to declare whether the remainder of the page can be reused again as an rx buffer. As a page may be reused, dma_sync_single_for_cpu() is added in order to sync the memory to the CPU side after it was owned by the HW. In addition, when the rx page can no longer be reused, it is being unmapped using dma_page_unmap(), which implicitly syncs and then unmaps the entire page. In case the kernel still handles the skbs pointing to the previous buffers from that rx page, it may access garbage pointers, caused by the implicit sync overwriting them. The implicit dma sync is removed by replacing dma_page_unmap() with dma_unmap_page_attrs() with DMA_ATTR_SKIP_CPU_SYNC flag. The functionality is disabled for XDP traffic to avoid handling several descriptors per packet.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux mlx5-updates-2023-06-09 1) Embedded CPU Virtual Functions 2) Lightweight local SFs Daniel Jurgens says: ==================== Embedded CPU Virtual Functions This series enables the creation of virtual functions on Bluefield (the embedded CPU platform). Embedded CPU virtual functions (EC VFs). EC VF creation, deletion and management interfaces are the same as those for virtual functions in a server with a Connect-X NIC. When using EC VFs on the ARM the creation of virtual functions on the host system is still supported. Host VFs eswitch vports occupy a range of 1..max_vfs, the EC VF vport range is max_vfs+1..max_ec_vfs. Every function (PF, ECPF, VF, EC VF, and subfunction) has a function ID associated with it. Prior to this series the function ID and the eswitch vport were the same. That is no longer the case, the EC VF function ID range is 1..max_ec_vfs. When querying or setting the capabilities of an EC VF function an new bit must be set in the query/set HCA cap structure. This is a high level overview of the changes made: - Allocate vports for EC VFs if they are enabled. - Create representors and devlink ports for the EC VF vports. - When querying/setting HCA caps by vport break the assumption that function ID is the same a vport number and adjust accordingly. - Create a new type of page, so that when SRIOV on the ARM is disabled, but remains enabled on the host, the driver can wait for the correct pages. - Update SRIOV code to support EC VF creation/deletion. =================== Lightweight local SFs: Last 3 patches form Shay Drory: SFs are heavy weight and by default they come with the full package of ConnectX features. Usually users want specialized SFs for one specific purpose and using devlink users will almost always override the set of advertises features of an SF and reload it. Shay Drory says: ================ In order to avoid the wasted time and resources on the reload, local SFs will probe without any auxiliary sub-device, so that the SFs can be configured prior to its full probe. The defaults of the enable_* devlink params of these SFs are set to false. Usage example: Create SF: $ devlink port add pci/0000:08:00.0 flavour pcisf pfnum 0 sfnum 11 $ devlink port function set pci/0000:08:00.0/32768 \ hw_addr 00:00:00:00:00:11 state active Enable ETH auxiliary device: $ devlink dev param set auxiliary/mlx5_core.sf.1 \ name enable_eth value true cmode driverinit Now, in order to fully probe the SF, use devlink reload: $ devlink dev reload auxiliary/mlx5_core.sf.1 At this point the user have SF devlink instance with auxiliary device for the Ethernet functionality only. ================

This series adds support for 4 ports VF LAG (single FDB E-Switch). This series of patches refactoring LAG code that make assumptions about VF LAG supporting only two ports and then enable 4 ports VF LAG. Patch 1: - Fix for ib rep code Patches 2-5: - Refactors LAG layer. Patches 6-7: - Block LAG types which doesn't support 4 ports. Patch 8: - Enable 4 ports VF LAG. This series specifically allows HCAs with 4 ports to create a VF LAG with only 4 ports. It is not possible to create a VF LAG with 2 or 3 ports using HCAs that have 4 ports. Currently, the Merged E-Switch feature only supports HCAs with 2 ports. However, upcoming patches will introduce support for HCAs with 4 ports. In order to activate VF LAG a user can execute: devlink dev eswitch set pci/0000:08:00.0 mode switchdev devlink dev eswitch set pci/0000:08:00.1 mode switchdev devlink dev eswitch set pci/0000:08:00.2 mode switchdev devlink dev eswitch set pci/0000:08:00.3 mode switchdev ip link add name bond0 type bond ip link set dev bond0 type bond mode 802.3ad ip link set dev eth2 master bond0 ip link set dev eth3 master bond0 ip link set dev eth4 master bond0 ip link set dev eth5 master bond0 Where eth2, eth3, eth4 and eth5 are net-interfaces of pci/0000:08:00.0 pci/0000:08:00.1 pci/0000:08:00.2 pci/0000:08:00.3 respectively.
