The only error that can happen during a nexthop dump is insufficient space in the skb caring the netlink messages (EMSGSIZE). If this happens and some messages were already filled in, the nexthop code returns the skb length to signal the netlink core that more objects need to be dumped. After commit b5a89915 ("netlink: handle EMSGSIZE errors in the core") there is no need to handle this error in the nexthop code as it is now handled in the core. Simplify the code and simply return the error to the core. No regressions in nexthop tests: # ./fib_nexthops.sh Tests passed: 234 Tests failed: 0 Signed-off-by:

Similar to skb_unref(), add skb_data_unref() to save an expensive atomic operation (and cache line dirtying) when last reference on shinfo->dataref is released. I saw this opportunity on hosts with RAW sockets accidentally bound to UDP protocol, forcing an skb_clone() on all received packets. These RAW sockets had their receive queue full, so all clone packets were immediately dropped. When UDP recvmsg() consumes later the original skb, skb_release_data() is hitting atomic_sub_return() quite badly, because skb->clone has been set permanently. Note that this patch helps TCP TX performance, because TCP stack also use (fast) clones. This means that at least one of the two packets (the main skb or its clone) will no longer have to perform this atomic operation in skb_release_data(). Signed-off-by:

Shannon Nelson says: ==================== ionic: putting ionic on a diet Building on the performance work done in the previous patchset [Link] https://lore.kernel.org/netdev/20240229193935.14197-1-shannon.nelson@amd.com/ this patchset puts the ionic driver on a diet, decreasing the memory requirements per queue, and simplifies a few more bits of logic. We trimmed the queue management structs and gained some ground, but the most savings came from trimming the individual buffer descriptors. The original design used a single generic buffer descriptor for Tx, Rx and Adminq needs, but the Rx and Adminq descriptors really don't need all the info that the Tx descriptors track. By splitting up the descriptor types we can significantly reduce the descriptor sizes for Rx and Adminq use. There is a small reduction in the queue management structs, saving about 3 cachelines per queuepair: ionic_qcq: Before: /* size: 2176, cachelines: 34, members: 23 */ After: /* size: 2048, cachelines: 32, members: 23 */ We also remove an array of completion descriptor pointers, or about 8 Kbytes per queue. But the biggest savings came from splitting the desc_info struct into queue specific structs and trimming out what was unnecessary. Before: ionic_desc_info: /* size: 496, cachelines: 8, members: 10 */ After: ionic_tx_desc_info: /* size: 496, cachelines: 8, members: 6 */ ionic_rx_desc_info: /* size: 224, cachelines: 4, members: 2 */ ionic_admin_desc_info: /* size: 8, cachelines: 1, members: 1 */ In a 64 core host the ionic driver will default to 64 queuepairs of 1024 descriptors for Rx, 1024 for Tx, and 80 for Adminq and Notifyq. The total memory usage for 64 queues: Before: 65 * sizeof(ionic_qcq) 141,440 + 64 * 1024 * sizeof(ionic_desc_info) 32,505,856 + 64 * 1024 * sizeof(ionic_desc_info) 32,505,856 + 64 * 1024 * 2 * sizeof(ionic_qc_info) 16,384 + 1 * 80 * sizeof(ionic_desc_info) 39,690 ---------- 65,201,038 After: 65 * sizeof(ionic_qcq) 133,120 + 64 * 1024 * sizeof(ionic_tx_desc_info) 32,505,856 + 64 * 1024 * sizeof(ionic_rx_desc_info) 14,680,064 + (removed) 0 + 1 * 80 * sizeof(ionic_admin desc_info) 640 ---------- 47,319,680 This saves us approximately 18 Mbytes per port in a 64 core machine, a 28% savings in our memory needs. In addition, this improves our simple single thread / single queue iperf case on a 9100 MTU connection from 86.7 to 95 Gbits/sec. ==================== Signed-off-by: -

Make desc_info structure specific to the queue type, which allows us to cut down the Rx and AdminQ descriptor sizes by not including all the fields needed for the Tx desriptors. Before: struct ionic_desc_info { /* size: 464, cachelines: 8, members: 6 */ After: struct ionic_tx_desc_info { /* size: 464, cachelines: 8, members: 6 */ struct ionic_rx_desc_info { /* size: 224, cachelines: 4, members: 2 */ struct ionic_admin_desc_info { /* size: 8, cachelines: 1, members: 1 */ Suggested-by: -

With a little simple math we don't need another struct array to find the completion structs, so we can remove the ionic_cq_info altogether. This doesn't really save anything in the ionic_cq since it gets padded out to the cacheline, but it does remove the parallel array allocation of 8 * num_descriptors, or about 8 Kbytes per queue in a default configuration.

By reworking the queue service routines to have their own servicing loops we can remove the cb pointer from desc_info to save another 8 bytes per descriptor, This simplifies some of the queue handling indirection and makes the code a little easier to follow, and keeps service code in one place rather than jumping between code files. struct ionic_desc_info Before: /* size: 472, cachelines: 8, members: 7 */ After: /* size: 464, cachelines: 8, members: 6 */ Suggested-by:

Move the AdminQ and NotifyQ queue handling to ionic_main.c with the rest of the adminq code. Suggested-by:

Now that we're not using desc_info pointers mapped in every q we can simplify and drop the unnecessary utility functions. Reviewed-by:

Remove the struct pointers from desc_info to use less space. Instead of pointers in every desc_info to its descriptor, we can use the queue descriptor index to find the individual desc, desc_info, and sgl structs in their parallel arrays. struct ionic_desc_info Before: /* size: 496, cachelines: 8, members: 10 */ After: /* size: 472, cachelines: 8, members: 7 */ Suggested-by:

Jeff was retired as the Intel driver maintainer in commit 6667df91 ("MAINTAINERS: Update MAINTAINERS for Intel ethernet drivers"), and his address bounces. But he has signed-off a lot of patches over the years so get_maintainer insists on CCing him. We haven't heard from him since he left Intel, so remapping the address via mailmap is also pointless. Add to ignored addresses. Signed-off-by:

inet6_dump_addr() can use the new xa_array iterator for better scalability. Make it ready for RCU-only protection. RTNL use is removed in the following patch. Also properly return 0 at the end of a dump to avoid and extra recvmsg() to get NLMSG_DONE. Signed-off-by:
