Function tc_dump_chain() obtains and releases block->lock on each iteration of its inner loop that dumps all chains on block. Outputting chain template info is fast operation so locking/unlocking mutex multiple times is an overhead when lock is highly contested. Modify tc_dump_chain() to only obtain block->lock once and dump all chains without releasing it. Signed-off-by:

Using tcf_walker->stop flag to determine when tcf_walker->fn() was called at least once is unreliable. Some classifiers set 'stop' flag on error before calling walker callback, other classifiers used to call it with NULL filter pointer when empty. In order to prevent further regressions, extend tcf_walker structure with dedicated 'nonempty' flag. Set this flag in tcf_walker->fn() implementation that is used to check if classifier has filters configured.

The Topaz family should have different phylink_validate method from the Peridot, since on Topaz the port supporting 2500BaseX mode is port 5, not 9 and 10. Signed-off-by:

Commit 787799a9 sets the SERDES interfaces of 6390 and 6390X to 1000BaseX, but this is only needed on 6390X, since there are SERDES interfaces which can be used on lower ports on 6390. This commit fixes this by returning to previous behaviour on 6390. (Previous behaviour means that CMODE is not set at all if requested mode is NA). This is needed on Turris MOX, where the 88e6190 is connected to CPU in 2500BaseX mode. Fixes: 787799a9 ("net: dsa: mv88e6xxx: Default ports 9/10 6390X CMODE to 1000BaseX") Signed-off-by:

With the switch to phy_resolve_aneg_linkmode() we don't read from the chip any longer what is advertised but use phydev->advertising directly. For a fixed phy however this bitmap is empty so far, what results in no common mode being found. This breaks DSA. Fix this by advertising everything that is supported. For a normal phy this done by phy_probe(). Fixes: 5502b218 ("net: phy: use phy_resolve_aneg_linkmode in genphy_read_status") Signed-off-by:

The patch enables returning 'type' in msghdr for records that are retrieved with MSG_PEEK in recvmsg. Further it prevents records peeked from socket from getting clubbed with any other record of different type when records are subsequently dequeued from strparser. For each record, we now retain its type in sk_buff's control buffer cb[]. Inside control buffer, record's full length and offset are already stored by strparser in 'struct strp_msg'. We store record type after 'struct strp_msg' inside 'struct tls_msg'. For tls1.2, the type is stored just after record dequeue. For tls1.3, the type is stored after record has been decrypted. Inside process_rx_list(), before processing a non-data record, we check that we must be able to return back the record type to the user application. If not, the decrypted records in tls context's rx_list is left there without consuming any data. Fixes: 692d7b5d ("tls: Fix recvmsg() to be able to peek across multiple records") Signed-off-by:

Presently the hns reset_type for the roce errors is set in the hclge_log_and_clear_rocee_ras_error function. This function is also called to detect and clear roce errors while enabling the rdma error interrupts. However there is no hns reset requested for this case. This can cause issue of wrong reset_type used with subsequent hns reset as the reset_type set in the above case was not cleared. This patch moves setting of hns reset_type for the roce errors from hclge_log_and_clear_rocee_ras_error function to hclge_handle_rocee_ras_error.

Ido Schimmel says: ==================== mlxsw: spectrum_acl: Don't take rtnl mutex for region rehash Jiri says: During region rehash, a new region is created with a more optimized set of masks (ERPs). When transitioning to the new region, all the rules from the old region are copied one-by-one to the new region. This transition can be time consuming and currently done under RTNL lock. In order to remove RTNL lock dependency during region rehash, introduce multiple smaller locks guarding dedicated structures or parts of them. That is the vast majority of this patchset. Only patch #1 is simple cleanup and patches 12-15 are improving or introducing new selftests. ==================== Signed-off-by: -
