Saeed Mahameed says: ==================== mlx5-updates-2022-03-09 1) Remove kernel log prints on FW events regarding FW pages management and replace that with debugfs entries to track FW pages management commands failures and general stats, we do that for all FW commands in general since it's the same effort to do so under the already existing debugfs entry for FW commands. 2) Add support for ConnectX-7 Software managed steering, in other words STEv2 which shares a lot in common with STE V1, the difference is in specific offsets in the devices, the logic is almost the same, thus we implement STEv1 and STEv2 in the same file. * tag 'mlx5-updates-2022-03-09' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: net/mlx5: DR, Add support for ConnectX-7 steering net/mlx5: DR, Refactor ste_ctx handling for STE v0/1 net/mlx5: DR, Rename action modify fields to reflect naming in HW spec net/mlx5: DR, Fix handling of different actions on the same STE in STEv1 net/mlx5: DR, Remove unneeded comments net/mlx5: DR, Add support for matching on Internet Header Length (IHL) net/mlx5: DR, Align mlx5dv_dr API vport action with FW behavior net/mlx5: Add debugfs counters for page commands failures net/mlx5: Add pages debugfs net/mlx5: Move debugfs entries to separate struct net/mlx5: Change release_all_pages cap bit location net/mlx5: Remove redundant error on reclaim pages net/mlx5: Remove redundant error on give pages net/mlx5: Remove redundant notify fail on give pages net/mlx5: Add command failures data to debugfs net/mlx5e: TC, Fix use after free in mlx5e_clone_flow_attr_for_post_act() ==================== Link: https://lore.kernel.org/r/20220309213755.610202-1-saeed@kernel.orgSigned-off-by: Jakub Kicinski <kuba@kernel.org>

Mat Martineau says: ==================== mptcp: selftests: Refactor join tests The mptcp_join.sh selftest is the largest and most complex self test for MPTCP, and it is frequently used by MPTCP developers to reproduce bugs and verify fixes. As it grew in size and execution time, it became more cumbersome to use. These changes do some much-needed cleanup, and add developer-friendly features to make it easier to see failures and run a subset of the tests when verifying fixes. ==================== Link: https://lore.kernel.org/r/20220309191636.258232-1-mathew.j.martineau@linux.intel.comSigned-off-by: Jakub Kicinski <kuba@kernel.org>

This fixes a few issues reported by ShellCheck: - SC2068: Double quote array expansions to avoid re-splitting elements. - SC2206: Quote to prevent word splitting/globbing, or split robustly with mapfile or read -a. - SC2166: Prefer [ p ] && [ q ] as [ p -a q ] is not well defined. - SC2155: Declare and assign separately to avoid masking return values. - SC2162: read without -r will mangle backslashes. - SC2219: Instead of 'let expr', prefer (( expr )) . - SC2181: Check exit code directly with e.g. 'if mycmd;', not indirectly with $?. - SC2236: Use -n instead of ! -z. - SC2004: $/${} is unnecessary on arithmetic variables. - SC2012: Use find instead of ls to better handle non-alphanumeric filenames. - SC2002: Useless cat. Consider 'cmd < file | ..' or 'cmd file | ..' instead. SC2086 (Double quotes to prevent globbing and word splitting) is ignored because it is controlled for the moment and there are too many to change. While at it, also fixed the alignment in one comment.

Some vars are redefined in different places. Best to avoid this classical Bash pitfall where variables are accidentally overridden by other functions because the proper scope has not been defined. Most issues are with loops: typically 'i' is used in for-loops but if it is not global, calling a function from a for-loop also doing a for-loop with the same non local 'i' variable causes troubles because the first 'i' will be assigned to another value. To prevent such issues, the iterator variable is now declared as local just before the loop. If it is always done like this, issues are avoided. To distinct between local and non local variables, all non local ones are defined at the beginning of the script. The others are now defined with the "local" keyword.

Running a specific test by giving the ID is often what we want: the CI reports an issue with the Nth test, it is reproducible with: ./mptcp_join.sh N But this might not work when there is a need to find which commit has introduced a regression making a test unstable: failing from time to time. Indeed, a specific test is not attached to one ID: the ID is in fact a counter. It means the same test can have a different ID if other tests have been added/removed before this unstable one. Remembering the current test can also help listing failed tests at the end.

Often, it is needed to run one specific test. There are options to run subgroups of tests but when only one fails, no need to run all the subgroup. So far, the solution was to edit the script to comment the tests that are not needed but that's not ideal. Now, it is possible to run one specific test by giving the ID of the tests that are going to be validated, e.g. ./mptcp_join.sh 36 37 This is cleaner and saves time. Technically, the reset* functions now return 0 if the test can be executed. This naturally creates sections per test in the code which is also helpful to understand what a test is exactly doing.

When adding a new tests group, it has to be defined in multiple places: - in the all_tests() function - in the 'usage()' function - in the getopts: short option + what to do when the option is used Because it is easy to forget one of them, it is useful to have to define them only once. Note: only using an associative array would simplify the code but the entries are stored in a hashtable and iterating over the different items doesn't give the same order as the one used in the declaration of this array. Because we want to run these tests in the same order as before, a "simple" array is used first.

Back when tcp_tso_autosize() and TCP pacing were introduced, our focus was really to reduce burst sizes for long distance flows. The simple heuristic of using sk_pacing_rate/1024 has worked well, but can lead to too small packets for hosts in the same rack/cluster, when thousands of flows compete for the bottleneck. Neal Cardwell had the idea of making the TSO burst size a function of both sk_pacing_rate and tcp_min_rtt() Indeed, for local flows, sending bigger bursts is better to reduce cpu costs, as occasional losses can be repaired quite fast. This patch is based on Neal Cardwell implementation done more than two years ago. bbr is adjusting max_pacing_rate based on measured bandwidth, while cubic would over estimate max_pacing_rate. /proc/sys/net/ipv4/tcp_tso_rtt_log can be used to tune or disable this new feature, in logarithmic steps. Tested: 100Gbit NIC, two hosts in the same rack, 4K MTU. 600 flows rate-limited to 20000000 bytes per second.

tcp_should_autocork() is evaluating if it makes senses to not immediately send current skb, hoping that user space will add more payload on it by the time TCP stack reacts to upcoming TX completions. If current skb got MSG_EOR mark, then we know that no further data will be added, it is therefore futile to wait. SOF_TIMESTAMPING_TX_ACK will become a bit more accurate, if prior packets are still in qdisc/device queues.

Dimitris Michailidis says: ==================== net/fungible: fix errors when CONFIG_TLS_DEVICE=n This pair of patches fix compile errors in funeth when CONFIG_TLS_DEVICE=n. The errors are due to symbols that are not defined in this config but are used in code guarded by "if (IS_ENABLED(CONFIG_TLS_DEVICE) ..." One option is to place this code under preprocessor guards that will keep the compiler from looking at the code. The option adopted here is to define the offending symbols also when CONFIG_TLS_DEVICE=n. The first patch does this for two functions in tls.h. The second does the same for driver symbols and makes tls.h inclusion unconditional. ==================== Link: https://lore.kernel.org/r/20220309034032.405212-1-dmichail@fungible.comSigned-off-by: Jakub Kicinski <kuba@kernel.org>

This chips supports two ways to configure max MTU size: - by setting SW_LEGAL_PACKET_DISABLE bit: if this bit is 0 allowed packed size will be between 64 and bytes 1518. If this bit is 1, it will accept packets up to 2000 bytes. - by setting SW_JUMBO_PACKET bit. If this bit is set, the chip will ignore SW_LEGAL_PACKET_DISABLE value and use REG_SW_MTU__2 register to configure MTU size. Current driver has disabled SW_JUMBO_PACKET bit and activates SW_LEGAL_PACKET_DISABLE. So the switch will pass all packets up to 2000 without any way to configure it. By providing port_change_mtu we are switch to SW_JUMBO_PACKET way and will be able to configure MTU up to ~9000.

As preparation for supporting ConnectX-7, rename action modify fields steering registers from arbitrary names to the names that reflect the corresponding naming and location of the steering registers in HW. These registers mapping has changed in ConnectX-7, so the renaming allows to keep track of their mapping better.

This aligns the behavior with FW when creating an FDB rule with wire vport destination but no source port matching. Until now such rules would fail on internal DR RX rule creation since the source and destination are the wire vport. The new behavior is the same as done on FW steering, if destination is wire, we will create both TX and RX rules, but the RX packet coming from wire will be dropped due to loopback not supported.

mlx5 FW has changed release_all_pages cap bit by one bit offset to reflect a fix in the FW flow for release_all_pages. The driver should use the new bit to ensure it calls release_all_pages only if the FW fix is there.
