Use the fdma_dcb_add() function to add DCB's in the rx path. This gets rid of the open-coding of nextptr and dataptr handling and leaves it to the library. Signed-off-by:

Use the two functions: fdma_alloc_phys() and fdma_dcb_init() for rx buffer allocation and use the new buffers throughout. In order to replace the old buffers with the new ones, we have to do the following refactoring: - use fdma_alloc_phys() and fdma_dcb_init() - replace the variables: rx->dma, rx->dcb_entries and rx->last_entry with the equivalents from the FDMA struct. - replace uses of sparx5_db_hw and sparx5_rx_dcb_hw with fdma_db and fdma_dcb. - add sparx5_fdma_rx_dataptr_cb callback for obtaining the dataptr. - Initialize FDMA struct values.

Replace the old rx and tx variables: channel_id, FDMA_DCB_MAX, FDMA_RX_DCB_MAX_DBS, FDMA_TX_DCB_MAX_DBS, dcb_index and db_index with the equivalents from the FDMA rx and tx structs. These variables are not entangled in any buffer allocation and can therefore be replaced in advance. Signed-off-by:

This reverts commit bf4d87f8 because it introduced dev_err_probe() in non-probe path, which is not desired. In general, calling dev_err_probe() after successful probe in case of handling -EPROBE_DEFER error, will set deferred status on the device already probed. This is however not a problem here now, because dev_err_probe() in affected places is used for handling errors from request_firmware(), which does not return -EPROBE_DEFER. Still usage of dev_err_probe() in such case is not correct, because request_firmware() could once return -EPROBE_DEFER. Fixes: bf4d87f8 ("net: alacritech: Switch to use dev_err_probe()") Signed-off-by:

This update allows listing default firewalld ruleset on Fedora 40 via tools/net/ynl/cli.py --spec \ Documentation/netlink/specs/nftables.yaml --dump getrule Default ruleset uses fib, reject and objref expressions which were missing. Other missing expressions can be added later.

Matthieu Baerts says: ==================== mptcp: MIB counters for MPJ TX + misc improvements Recently, a few issues have been discovered around the creation of additional subflows. Without these counters, it was difficult to point out the reason why some subflows were not created as expected. In patch 3, all error paths from __mptcp_subflow_connect() are covered, except the one related to the 'fully established mode', because it can only happen with the userspace PM, which will propagate the error to the userspace in this case (ENOTCONN). These new counters are also verified in the MPTCP Join selftest in patch 6. While at it, a few other patches are improving the MPTCP path-manager code ... - Patch 1: 'flush' related helpers are renamed to avoid confusions - Patch 2: directly pass known ID and flags to create a new subflow, i/o getting them later by iterating over all endpoints again ... and the MPJoin selftests: - Patch 4: reduce the number of positional parameters - Patch 5: only one line for the 'join' checks, instead of 3 - Patch 7: more explicit check names, instead of sometimes too cryptic ones: rtx, ptx, ftx, ctx, fclzrx, sum - Patch 8: specify client/server instead of 'invert' for some checks not suggesting one specific direction - Patch 9: mute errors of mptcp_connect when ran in the background - Patch 10: simplify checksum_tests by using a for-loop - Patch 11: remove 'define' re-definitions ==================== Link: https://patch.msgid.link/20240902-net-next-mptcp-mib-mpjtx-misc-v1-0-d3e0f3773b90@kernel.orgSigned-off-by: -

'MPTCP_PM_NAME' is defined in 'linux/mptcp_pm.h', included in 'linux/mptcp.h', no need to re-define it. 'MPTCP_PM_EVENTS' is not defined in 'linux/mptcp.h', but 'MPTCP_PM_EV_GRP_NAME' is, with the same value. We can then use the latter, and drop the other one. Reviewed-by:

The test is supposed to be killed before the end, which will likely cause "Connection reset by peer" errors. It is confusing, especially because in case of real transfer errors, the test will not be marked as failed. But that's OK, there are many other tests checking that. Reviewed-by:

Instead of displaying 'invert' when looking at some events like MP_FAIL, MP_FASTCLOSE, MP_RESET, RM_ADDR, which is a bit vague because they are not traditionnaly sent from one side, the host being checked is now printed. For the ADD_ADDR, only display the host when it is the client sending it, which is more unusual. Also before, the 'invert' message was printed after a few checks, but it was not clear which ones exactly. Reviewed-by:

Before, the check names had to be very short. It is no longer the case now that these checks are printed on a dedicated line. Then, it looks better to have more explicit names. Reviewed-by:

A few new MPJoinSynTx MIB counters have been added in a previous commit. They are being validated here in mptcp_join.sh selftest, each time the number of received MPJ are checked. Most of the time, the number of sent SYN+MPJ is the same as the received ones. But sometimes, there are more, because there are dropped, or there are errors. While at it, the "no MPC reuse with single endpoint" subtest has been modified to force a bind() error. Reviewed-by:

Most tests are checking if the expected number of SYN/SYN+ACK/ACK JOINs have been received, each of them on one line. More Join related tests are going to be checked soon, no need to add 5 new lines per test in case of success, just one is enough. In case of issue, the errors will still be reported like before.

chk_join_nr() currently takes 9 positional parameters, 6 of them are optional. It makes it hard to read: chk_join_nr 1 1 1 1 0 1 1 0 4 Naming these vars helps to make it easier to read: join_csum_ns1=1 join_csum_ns2=0 \ join_fail_nr=1 join_rst_nr=1 join_infi_nr=0 \ join_corrupted_pkts=4 \ chk_join_nr 1 1 1 It will then be easier to add new optional parameters.

Recently, a few issues have been discovered around the creation of additional subflows. Without these counters, it was difficult to point out the reason why some subflows were not created as expected. These counters should have been added earlier, because there is no other simple ways to extract such information from the kernel, and understand why subflows have not been created. While at it, some pr_debug() have been added, just in case the errno needs to be printed. Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/509Reviewed-by:

__mptcp_subflow_connect() is currently called from the path-managers, which have all the required information to create subflows. No need to call the PM again to re-iterate over the list of entries with RCU lock to get more info. Instead, it is possible to pass a mptcp_pm_addr_entry structure, instead of a mptcp_addr_info one. The former contains the ifindex and the flags that are required when creating the new subflow. This is a partial revert of commit ee285257 ("mptcp: drop flags and ifindex arguments"). While at it, the local ID can also be set if it is known and 0, to avoid having to set it in the 'rebuild_header' hook, which will cause a new iteration of the endpoint entries. Reviewed-by:

Rename all the helpers specific to the flushing operations to make it clear that the intention is to flush all created subflows, and remove all announced addresses, not just a specific selection. That way, it is easier to understand why the id_avail_bitmap and local_addr_used are reset at the end. Reviewed-by:

All drivers will now report RX software timestamp as supported. The series is limited to 15 patches, I will submit other drivers in subsequent submissions.
