Currently, netif_tx_stop_all_queues() is used to ensure that the xmit is not running, but for the concurrent case it will not take effect, since netif_tx_stop_all_queues() just sets a flag without locking to indicate that the xmit queue(s) should not be run. So use netif_tx_disable() to replace netif_tx_stop_all_queues(), it takes the xmit queue lock while marking the queue stopped.

When skb->ip_summed is CHECKSUM_PARTIAL, for non-tunnel udp packet, which has a dest port as the IANA assigned, the hardware is expected to do the checksum offload, but the hardware whose version is below V3 will not do the checksum offload when udp dest port is 4790. So fixes it by doing the checksum in software for this case. Fixes: 76ad4f0e ("net: hns3: Add support of HNS3 Ethernet Driver for hip08 SoC") Signed-off-by:

An issue found when network interface is down and up again, FPE handshake fails to trigger. This is due to __FPE_REMOVING bit remains being set in stmmac_fpe_stop_wq() but not cleared in stmmac_fpe_start_wq(). This cause FPE workqueue task, stmmac_fpe_lp_task() not able to be executed. To fix this, add clearing __FPE_REMOVING bit in stmmac_fpe_start_wq(). Fixes: 5a558611 ("net: stmmac: support FPE link partner hand-shaking procedure") Signed-off-by:

This patch provides counters for SRv6 Behaviors as defined in [1], section 6. For each SRv6 Behavior instance, counters defined in [1] are: - the total number of packets that have been correctly processed; - the total amount of traffic in bytes of all packets that have been correctly processed; In addition, this patch introduces a new counter that counts the number of packets that have NOT been properly processed (i.e. errors) by an SRv6 Behavior instance. Counters are not only interesting for network monitoring purposes (i.e. counting the number of packets processed by a given behavior) but they also provide a simple tool for checking whether a behavior instance is working as we expect or not. Counters can be useful for troubleshooting misconfigured SRv6 networks. Indeed, an SRv6 Behavior can silently drop packets for very different reasons (i.e. wrong SID configuration, interfaces set with SID addresses, etc) without any notification/message to the user. Due to the nature of SRv6 networks, diagnostic tools such as ping and traceroute may be ineffective: paths used for reaching a given router can be totally different from the ones followed by probe packets. In addition, paths are often asymmetrical and this makes it even more difficult to keep up with the journey of the packets and to understand which behaviors are actually processing our traffic. When counters are enabled on an SRv6 Behavior instance, it is possible to verify if packets are actually processed by such behavior and what is the outcome of the processing. Therefore, the counters for SRv6 Behaviors offer an non-invasive observability point which can be leveraged for both traffic monitoring and troubleshooting purposes. [1] https://www.rfc-editor.org/rfc/rfc8986.html#name-counters Troubleshooting using SRv6 Behavior counters -------------------------------------------- Let's make a brief example to see how helpful counters can be for SRv6 networks. Let's consider a node where an SRv6 End Behavior receives an SRv6 packet whose Segment Left (SL) is equal to 0. In this case, the End Behavior (which accepts only packets with SL >= 1) discards the packet and increases the error counter. This information can be leveraged by the network operator for troubleshooting. Indeed, the error counter is telling the user that the packet: (i) arrived at the node; (ii) the packet has been taken into account by the SRv6 End behavior; (iii) but an error has occurred during the processing. The error (iii) could be caused by different reasons, such as wrong route settings on the node or due to an invalid SID List carried by the SRv6 packet. Anyway, the error counter is used to exclude that the packet did not arrive at the node or it has not been processed by the behavior at all. Turning on/off counters for SRv6 Behaviors ------------------------------------------ Each SRv6 Behavior instance can be configured, at the time of its creation, to make use of counters. This is done through iproute2 which allows the user to create an SRv6 Behavior instance specifying the optional "count" attribute as shown in the following example: $ ip -6 route add 2001:db8::1 encap seg6local action End count dev eth0 per-behavior counters can be shown by adding "-s" to the iproute2 command line, i.e.: $ ip -s -6 route show 2001:db8::1 2001:db8::1 encap seg6local action End packets 0 bytes 0 errors 0 dev eth0 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Impact of counters for SRv6 Behaviors on performance ==================================================== To determine the performance impact due to the introduction of counters in the SRv6 Behavior subsystem, we have carried out extensive tests. We chose to test the throughput achieved by the SRv6 End.DX2 Behavior because, among all the other behaviors implemented so far, it reaches the highest throughput which is around 1.5 Mpps (per core at 2.4 GHz on a Xeon(R) CPU E5-2630 v3) on kernel 5.12-rc2 using packets of size ~ 100 bytes. Three different tests were conducted in order to evaluate the overall throughput of the SRv6 End.DX2 Behavior in the following scenarios: 1) vanilla kernel (without the SRv6 Behavior counters patch) and a single instance of an SRv6 End.DX2 Behavior; 2) patched kernel with SRv6 Behavior counters and a single instance of an SRv6 End.DX2 Behavior with counters turned off; 3) patched kernel with SRv6 Behavior counters and a single instance of SRv6 End.DX2 Behavior with counters turned on. All tests were performed on a testbed deployed on the CloudLab facilities [2], a flexible infrastructure dedicated to scientific research on the future of Cloud Computing. Results of tests are shown in the following table: Scenario (1): average 1504764,81 pps (~1504,76 kpps); std. dev 3956,82 pps Scenario (2): average 1501469,78 pps (~1501,47 kpps); std. dev 2979,85 pps Scenario (3): average 1501315,13 pps (~1501,32 kpps); std. dev 2956,00 pps As can be observed, throughputs achieved in scenarios (2),(3) did not suffer any observable degradation compared to scenario (1).

Pull xfs updates from Darrick Wong: "The notable user-visible addition this cycle is ability to remove space from the last AG in a filesystem. This is the first of many changes needed for full-fledged support for shrinking a filesystem. Still needed are (a) the ability to reorganize files and metadata away from the end of the fs; (b) the ability to remove entire allocation groups; (c) shrink support for realtime volumes; and (d) thorough testing of (a-c). There are a number of performance improvements in this code drop: Dave streamlined various parts of the buffer logging code and reduced the cost of various debugging checks, and added the ability to pre-create the xattr structures while creating files. Brian eliminated transaction reservations that were being held across writeback (thus reducing livelock potential. Other random pieces: Pavel fixed the repetitve warnings about deprecated mount options, I fixed online fsck to behave itself when a readonly remount comes in during scrub, and refactored various other parts of that code, Christoph contributed a lot of refactoring this cycle. The xfs_icdinode structure has been absorbed into the (incore) xfs_inode structure, and the format and flags handling around xfs_inode_fork structures has been simplified. Chandan provided a number of fixes for extent count overflow related problems that have been shaken out by debugging knobs added during 5.12. Summary: - Various minor fixes in online scrub. - Prevent metadata files from being automatically inactivated. - Validate btree heights by the computed per-btree limits. - Don't warn about remounting with deprecated mount options. - Initialize attr forks at create time if we suspect we're going to need to store them. - Reduce memory reallocation workouts in the logging code. - Fix some theoretical math calculation errors in logged buffers that span multiple discontig memory ranges but contiguous ondisk regions. - Speedups in dirty buffer bitmap handling. - Make type verifier functions more inline-happy to reduce overhead. - Reduce debug overhead in directory checking code. - Many many typo fixes. - Begin to handle the permanent loss of the very end of a filesystem. - Fold struct xfs_icdinode into xfs_inode. - Deprecate the long defunct BMV_IF_NO_DMAPI_READ from the bmapx ioctl. - Remove a broken directory block format check from online scrub. - Fix a bug where we could produce an unnecessarily tall data fork btree when creating an attr fork. - Fix scrub and readonly remounts racing. - Fix a writeback ioend log deadlock problem by dropping the behavior where we could preallocate a setfilesize transaction. - Fix some bugs in the new extent count checking code. - Fix some bugs in the attr fork preallocation code. - Refactor if_flags out of the incore inode fork data structure" * tag 'xfs-5.13-merge-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (77 commits) xfs: remove xfs_quiesce_attr declaration xfs: remove XFS_IFEXTENTS xfs: remove XFS_IFINLINE xfs: remove XFS_IFBROOT xfs: only look at the fork format in xfs_idestroy_fork xfs: simplify xfs_attr_remove_args xfs: rename and simplify xfs_bmap_one_block xfs: move the XFS_IFEXTENTS check into xfs_iread_extents xfs: drop unnecessary setfilesize helper xfs: drop unused ioend private merge and setfilesize code xfs: open code ioend needs workqueue helper xfs: drop submit side trans alloc for append ioends xfs: fix return of uninitialized value in variable error xfs: get rid of the ip parameter to xchk_setup_* xfs: fix scrub and remount-ro protection when running scrub xfs: move the check for post-EOF mappings into xfs_can_free_eofblocks xfs: move the xfs_can_free_eofblocks call under the IOLOCK xfs: precalculate default inode attribute offset xfs: default attr fork size does not handle device inodes xfs: inode fork allocation depends on XFS_IFEXTENT flag ... -

Pull clk updates from Stephen Boyd: "Here's a collection of largely clk driver updates. The usual suspects are here: i.MX, Qualcomm, Renesas, Allwinner, Samsung, and Rockchip, but it feels pretty light on commits. There's only one real commit to the framework core and that's to consolidate code. Otherwise the diffstat is dominated by many Qualcomm clk driver patches that modernize the driver for the proper way of speciying clk parents. That's shifting data around, which could subtly break things so I'll be on the lookout for fixes.
