When a packet enters the OVS datapath and does not match any existing flows installed in the kernel flow cache, the packet will be sent to userspace to be parsed, and a new flow will be created. The kernel and OVS rely on each other to parse packet fields in the same way so that packets will be handled properly. As per the design document linked below, OVS expects all later IPv6 fragments to have nw_proto=44 in the flow key, so they can be correctly matched on OpenFlow rules. OpenFlow controllers create pipelines based on this design. This behavior was changed by the commit in the Fixes tag so that nw_proto equals the next_header field of the last extension header. However, there is no counterpart for this change in OVS userspace, meaning that this field is parsed differently between OVS and the kernel. This is a problem because OVS creates actions based on what is parsed in userspace, but the kernel-provided flow key is used as a match criteria, as described in Documentation/networking/openvswitch.rst. This leads to issues such as packets incorrectly matching on a flow and thus the wrong list of actions being applied to the packet. Such changes in packet parsing cannot be implemented without breaking the userspace. The offending commit is partially reverted to restore the expected behavior. The change technically made sense and there is a good reason that it was implemented, but it does not comply with the original design of OVS. If in the future someone wants to implement such a change, then it must be user-configurable and disabled by default to preserve backwards compatibility with existing OVS versions.

Commit 8a59f9d1 ("sock: Introduce sk->sk_prot->psock_update_sk_prot()") has moved the inet_csk_has_ulp(sk) check from sk_psock_init() to the new tcp_bpf_update_proto() function. I'm guessing that this was done to allow creating psocks for non-inet sockets. Unfortunately the destruction path for psock includes the ULP unwind, so we need to fail the sk_psock_init() itself. Otherwise if ULP is already present we'll notice that later, and call tcp_update_ulp() with the sk_proto of the ULP itself, which will most likely result in the ULP looping its callbacks.

The following sequence currently causes a driver bug warning when using virtio_net: # ip link set eth0 up # echo mem > /sys/power/state (or e.g. # rtcwake -s 10 -m mem) <resume> # ip link set eth0 down Missing register, driver bug WARNING: CPU: 0 PID: 375 at net/core/xdp.c:138 xdp_rxq_info_unreg+0x58/0x60 Call trace: xdp_rxq_info_unreg+0x58/0x60 virtnet_close+0x58/0xac __dev_close_many+0xac/0x140 __dev_change_flags+0xd8/0x210 dev_change_flags+0x24/0x64 do_setlink+0x230/0xdd0 ... This happens because virtnet_freeze() frees the receive_queue completely (including struct xdp_rxq_info) but does not call xdp_rxq_info_unreg(). Similarly, virtnet_restore() sets up the receive_queue again but does not call xdp_rxq_info_reg(). Actually, parts of virtnet_freeze_down() and virtnet_restore_up() are almost identical to virtnet_close() and virtnet_open(): only the calls to xdp_rxq_info_(un)reg() are missing. This means that we can fix this easily and avoid such problems in the future by just calling virtnet_close()/open() from the freeze/restore handlers. Aside from adding the missing xdp_rxq_info calls the only difference is that the refill work is only cancelled if netif_running(). However, this should not make any functional difference since the refill work should only be active if the network interface is actually up.

Intel I210 on some Intel Alder Lake platforms can only achieve ~750Mbps Tx speed via iperf. The RR2DCDELAY shows around 0x2xxx DMA delay, which will be significantly lower when 1) ASPM is disabled or 2) SoC package c-state stays above PC3. When the RR2DCDELAY is around 0x1xxx the Tx speed can reach to ~950Mbps. According to the I210 datasheet "8.26.1 PCIe Misc. Register - PCIEMISC", "DMA Idle Indication" doesn't seem to tie to DMA coalesce anymore, so set it to 1b for "DMA is considered idle when there is no Rx or Tx AND when there are no TLPs indicating that CPU is active detected on the PCIe link (such as the host executes CSR or Configuration register read or write operation)" and performing Tx should also fall under "active CPU on PCIe link" case. In addition to that, commit b6e0c419 ("igb: Move DMA Coalescing init code to separate function.") seems to wrongly changed from enabling E1000_PCIEMISC_LX_DECISION to disabling it, also fix that.

It was discovered that the Documentation lacks of a fundamental detail on how to correctly change the MAX_FRAME_SIZE of the switch. In fact if the MAX_FRAME_SIZE is changed while the cpu port is on, the switch panics and cease to send any packet. This cause the mgmt ethernet system to not receive any packet (the slow fallback still works) and makes the device not reachable. To recover from this a switch reset is required. To correctly handle this, turn off the cpu ports before changing the MAX_FRAME_SIZE and turn on again after the value is applied.

Under CONFIG_FORTIFY_SOURCE=y and CONFIG_UBSAN_BOUNDS=y, Clang is bugged here for calculating the size of the destination buffer (0x10 instead of 0x14). This copy is a fixed size (sizeof(struct fw_section_info_st)), with the source and dest being struct fw_section_info_st, so the memcpy should be safe, assuming the index is within bounds, which is UBSAN_BOUNDS's responsibility to figure out. Avoid the whole thing and just do a direct assignment. This results in no change to the executable code.

Pull 9pfs fixes from Dominique Martinet: "A couple of fid refcount and fscache fixes: - fid refcounting was incorrect in some corner cases and would leak resources, only freed at umount time. The first three commits fix three such cases - 'cache=loose' or fscache was broken when trying to write a partial page to a file with no read permission since the rework a few releases ago. The fix taken here is just to restore old behavior of using the special 'writeback_fid' for such reads, which is open as root/RDWR and such not get complains that we try to read on a WRONLY fid. Long-term it'd be nice to get rid of this and not issue the read at all (skip cache?) in such cases, but that direction hasn't progressed" * tag '9p-for-5.19-rc4' of https://github.com/martinetd/linux: 9p: fix EBADF errors in cached mode 9p: Fix refcounting during full path walks for fid lookups 9p: fix fid refcount leak in v9fs_vfs_get_link 9p: fix fid refcount leak in v9fs_vfs_atomic_open_dotl -

This reverts commit 8fc74d18. BAR0 is the main (only?) register bank for this device. We most obviously can't unmap it before the netdev is unregistered. This was pointed out in review but the patch got reposted and merged, anyway. The author of the patch was only testing it with a QEMU model, which I presume does not emulate enough for the netdev to be brought up (author's replies are not visible in lore because they kept sending their emails in HTML).

unix_table_locks are to protect the global hash table, unix_socket_table. The previous commit removed it, so let's clean up the unnecessary locks. Here is a test result on EC2 c5.9xlarge where 10 processes run concurrently in different netns and bind 100,000 sockets for each. without this series : 1m 38s with this series : 11s It is ~10x faster because the global hash table is split into 10 netns in this case.

This commit adds a per netns hash table for AF_UNIX, which size is fixed as UNIX_HASH_SIZE for now. The first implementation defines a per-netns hash table as a single array of lock and list: struct unix_hashbucket { spinlock_t lock; struct hlist_head head; }; struct netns_unix { struct unix_hashbucket *hash; ... }; But, Eric pointed out memory cost that the structure has holes because of sizeof(spinlock_t), which is 4 (or more if LOCKDEP is enabled). [0] It could be expensive on a host with thousands of netns and few AF_UNIX sockets. For this reason, a per-netns hash table uses two dense arrays. struct unix_table { spinlock_t *locks; struct hlist_head *buckets; }; struct netns_unix { struct unix_table table; ... }; Note the length of the list has a significant impact rather than lock contention, so having shared locks can be an option. But, per-netns locks and lists still perform better than the global locks and per-netns lists. [1] Also, this patch adds a change so that struct netns_unix disappears from struct net if CONFIG_UNIX is disabled.

Currently, the size of AF_UNIX hash table is UNIX_HASH_SIZE * 2, the first half for bind()ed sockets and the second half for unbound ones. UNIX_HASH_SIZE * 2 is used to define the table and iterate over it. In some places, we use ARRAY_SIZE(unix_socket_table) instead of UNIX_HASH_SIZE * 2. However, we cannot use it anymore because we will allocate the hash table dynamically. Then, we would have to add UNIX_HASH_SIZE * 2 in many places, which would be troublesome. This patch adapts the UNIX_HASH_SIZE definition to include bound and unbound sockets and defines a new UNIX_HASH_MOD macro to ease calculations. Signed-off-by:

Patches #2-#7 make various improvements in the layer 2 multicast code, making it more receptive towards upcoming changes. Patches #8-#10 prepare the CONFIG_PROFILE command for the unified bridge model. This command will be used to enable the new model in the last patchset.

rFID and dummy FID do not support FID->VNI mapping. Currently, these families do not implement the vni_{set, clear}() operations. Instead, there is a check if these functions are implemented. Similarly, 'SFMR.nve_tunnel_flood_ptr' is not relevant for rFID and dummy FID, therefore, these families do not implement nve_flood_index_{set, clear}(). Align the behavior to other unsupported operations, implement the functions and just return an error or warn. Then, checks like '!ops->vni_set' can be removed.

SFMR register contains a 'fid_offset' field which is used when flooding tables of type FID offset are used. Currently, the driver sets this field to zero, as flooding tables of type FID are used. Using unified bridge model, the driver will use FID offset flooding tables. As preparation, add 'fid_offset' to 'struct mlxsw_sp_fid'. Then, use this field instead of passing zero to the function that configures SFMR. Set the new field as part of 'ops->setup()', for that, implement this function for dummy FID and rFID.

Currently, as part of mlxsw_pci_init(), resources are queried from firmware before issuing the 'CONFIG_PROFILE' command. There are resources whose size depend on the enablement of the unified bridge model that is performed via 'CONFIG_PROFILE' command. As a preparation for unified bridge model, add an additional query after issuing this command. Both queries are required as KVD sizes are read from firmware and then are configured as part of 'CONFIG_PROFILE' command. Signed-off-by:

Currently, the length of 'config_profile.flood_mode' is defined as 2 bits, while the correct length is 3 bits. As preparation for unified bridge model, which will use the whole field length, fix it and increase the field to the correct size. Signed-off-by:
