The mediatek-ge PHY driver already disables EEE advertisement on the switch PHYs but my testing [1] shows that it is somehow enabled afterwards. Disabling EEE advertisement before the PHY driver initialises keeps it off. Therefore, remove disabling EEE advertisement here as it's useless.

In commit 18ff0bcd ("ethtool: add interface to interact with Ethernet Power Equipment"), the 'pse_control_config' structure was introduced, housing a single member labeled 'admin_cotrol' responsible for maintaining the operational state of the PoDL PSE functions. A noticeable typographical error exists in the naming of this field ('cotrol' should be corrected to 'control'), which this commit aims to rectify. Furthermore, with upcoming extensions of this structure to encompass PoE functionalities, the field is being renamed to 'podl_admin_state' to distinctly indicate that this state is tailored specifically for PoDL."

Commit dcf70df2 ("af_unix: Fix up unix_edge.successor for embryo socket.") added spin_lock(&unix_gc_lock) in accept() path, and it caused regression in a stress test as reported by kernel test robot. If the embryo socket is not part of the inflight graph, we need not hold the lock. To decide that in O(1) time and avoid the regression in the normal use case, 1. add a new stat unix_sk(sk)->scm_stat.nr_unix_fds 2. count the number of inflight AF_UNIX sockets in the receive queue under unix_state_lock() 3. move unix_update_edges() call under unix_state_lock() 4. avoid locking if nr_unix_fds is 0 in unix_update_edges() Reported-by:

Petr Machata says: ==================== selftests: Assortment of fixes This is a loose follow-up to the Kernel CI patchset posted recently. It contains various fixes that were supposed to be part of said patchset, but didn't fit due to its size. The latter 4 patches were written independently of the CI effort, but again didn't fit in their intended patchsets. - Patch #1 unifies code of two very similar looking functions, busywait() and slowwait(). - Patch #2 adds sanity checks around the setting of NETIFS, which carries list of interfaces to run on. - Patch #3 changes bail_on_lldpad() to SKIP instead of FAILing. - Patches #4 to #7 fix issues in selftests. - Patches #8 to #10 add topology diagrams to several selftests. This should have been part of the mlxsw leg of NH group stats patches, but again, it did not fit in due to size. ==================== Link: https://lore.kernel.org/r/cover.1712940759.git.petrm@nvidia.comSigned-off-by:

The ethtool dump includes the lanes parameter only when the port is up. Therefore, the ethtool_lanes.sh test waits for ports to come before testing the lanes parameter. In some cases, the test considers the port as up, but the lanes parameter is not yet dumped although assumed to be, resulting in ethtool_lanes.sh test failure. To avoid that, ensure that the lanes parameter is indeed dumped by waiting for it explicitly, before preforming the test cases. Signed-off-by:

The tests use the constant TC_HIT_TIMEOUT when waiting on the counter values. However it does not include tc_common.sh where the counter is specified. The test has been robust in our testing, which means the counter is bumped quickly enough that the updated value is available already on the first iteration. Nevertheless it's not correct. Include tc_common.sh as appropriate. Signed-off-by:

Some log_test calls are done in a loop, and lead to the same log output. This might prove tricky to deduplicate for automated tools. Instead, roll the unique information from log_info to log_test, and drop the log_info. This also leads to more compact and clearer output. This change prompts rewording the messages so that they are not excessively long. Some check_err messages do not indicate what the issue actually is, so reword them to say it's a "ping with", like is the case in some other instances in this test. Signed-off-by:

When rx-pktsNtoM reports a range that involves very low-valued range, such as 0-64, the calculated length of the packet will be -4, because FCS is subtracted from the value. mausezahn then confuses the value for an option and bails out. As a result, the test dumps many mausezahn error messages. Instead, cap the value at 0. mausezahn will use an appropriate minimum packet length.

Bodies of busywait() and slowwait() functions are almost identical. Extract the common code into a helper, loopy_wait, and convert busywait() and slowwait() into trivial wrappers. Moreover, the fact that slowwait() uses seconds for units is really not intuitive, and the comment does not help much. Instead make the unit part of the name of the argument to further clarify what units are expected. Cc: Hangbin Liu <liuhangbin@gmail.com> Signed-off-by:

Breno Leitao says: ==================== net: dqs: optimize if stall threshold is not set Here are four patches aimed at enhancing the Dynamic Queue Limit (DQL) subsystem within the networking stack. The first two commits involve code refactoring, while the third patch introduces the actual change. The fourth patch just improves the cache locality. Typically, when DQL is enabled, stall information is always populated through dql_queue_stall(). However, this information is only necessary if a stall threshold is set, which is stored in struct dql->stall_thrs. Although dql_queue_stall() is relatively inexpensive, it is not entirely free due to memory barriers and similar overheads. To optimize performance, refrain from calling dql_queue_stall() when no stall threshold is set, thus avoiding the processing of unnecessary information. v1: https://lore.kernel.org/all/20240404145939.3601097-1-leitao@debian.org/ ==================== Link: https://lore.kernel.org/r/20240411192241.2498631-1-leitao@debian.orgSigned-off-by:

With the previous change, struct dqs->stall_thrs will be in the hot path (at queue side), even if DQS is disabled. The other fields accessed in this function (last_obj_cnt and num_queued) are in the first cache line, let's move this field (stall_thrs) to the very first cache line, since there is a hole there. This does not change the structure size, since it moves an short (2 bytes) to 4-bytes whole in the first cache line. This is the new structure format now: struct dql { unsigned int num_queued; unsigned int last_obj_cnt; ... short unsigned int stall_thrs; /* XXX 2 bytes hole, try to pack */ ... /* --- cacheline 1 boundary (64 bytes) --- */ ... /* Longest stall detected, reported to user */ short unsigned int stall_max; /* XXX 2 bytes hole, try to pack */ }; Also, read the stall_thrs (now in the very first cache line) earlier, together with dql->num_queued (also in the first cache line).
