Commit c8992cff ("Bluetooth: hci_event: Use of a function table to handle Command Complete") was (presumably) meant to only refactor things without any functional changes. But it does have one undesirable side-effect, before *status would always be set to skb->data[0] and it might be overridden by some of the opcode specific handling. While now it always set by the opcode specific handlers. This means that if the opcode is not known *status does not get set any more at all! This behavior change has broken bluetooth support for BCM4343A0 HCIs, the hci_bcm.c code tries to configure UART attached HCIs at a higher baudraute using vendor specific opcodes. The BCM4343A0 does not support this and this used to simply fail: [ 25.646442] Bluetooth: hci0: BCM: failed to write clock (-56) [ 25.646481] Bluetooth: hci0: Failed to set baudrate After which things would continue with the initial baudraute. But now that hci_cmd_complete_evt() no longer sets status for unknown opcodes *status is left at 0. This causes the hci_bcm.c code to think the baudraute has been changed on the HCI side and to also adjust the UART baudrate, after which communication with the HCI is broken, leading to: [ 28.579042] Bluetooth: hci0: command 0x0c03 tx timeout [ 36.961601] Bluetooth: hci0: BCM: Reset failed (-110) And non working bluetooth. Fix this by restoring the previous default "*status = skb->data[0]" handling for unknown opcodes.

Use try_cmpxchg instead of cmpxchg (*ptr, old, new) == old in napi_if_scheduled_mark_missed. x86 CMPXCHG instruction returns success in ZF flag, so this change saves a compare after cmpxchg (and related move instruction in front of cmpxchg). Also, try_cmpxchg implicitly assigns old *ptr value to "old" when cmpxchg fails, enabling further code simplifications.

Jiri Pirko says: ==================== net: devlink: sync flash and dev info commands Purpose of this patchset is to introduce consistency between two devlink commands: devlink dev info Shows versions of running default flash target and components. devlink dev flash Flashes default flash target or component name (if specified on cmdline). Currently it is up to the driver what versions to expose and what flash update component names to accept. This is inconsistent. Thankfully, only netdevsim currently using components so it is still time to sanitize this. This patchset makes sure, that devlink.c calls into driver for component flash update only in case the driver exposes the same version name. Example: $ devlink dev info netdevsim/netdevsim10: driver netdevsim versions: running: fw.mgmt 10.20.30 stored: fw.mgmt 10.20.30 $ devlink dev flash netdevsim/netdevsim10 file somefile.bin [fw.mgmt] Preparing to flash [fw.mgmt] Flashing 100% [fw.mgmt] Flash select [fw.mgmt] Flashing done $ devlink dev flash netdevsim/netdevsim10 file somefile.bin component fw.mgmt [fw.mgmt] Preparing to flash [fw.mgmt] Flashing 100% [fw.mgmt] Flash select [fw.mgmt] Flashing done $ devlink dev flash netdevsim/netdevsim10 file somefile.bin component dummy Error: selected component is not supported by this device. ==================== Link: https://lore.kernel.org/r/20220824122011.1204330-1-jiri@resnulli.usSigned-off-by: -

Limit the acceptance of component name passed to cmd_flash_update() to match one of the versions returned by info_get(), marked by version type. This makes things clearer and enforces 1:1 mapping between exposed version and accepted flash component. Check VERSION_TYPE_COMPONENT version type during cmd_flash_update() execution by calling info_get() with different "req" context. That causes info_get() to lookup the component name instead of filling-up the netlink message. Remove "UPDATE_COMPONENT" flag which becomes used. Signed-off-by:

Whenever the driver is called by his info_get() op, it may put multiple version names and values to the netlink message. Extend by additional helper devlink_info_version_running/stored_put_ext() that allows to specify a version type that indicates when particular version name represents a flash component. This is going to be used in follow-up patch calling info_get() during flash update command checking if version with this the version type exists. Signed-off-by:

When config tc filter match ct_state(0/0x3f), dissector->used_keys with FLOW_DISSECTOR_KEY_CT bit, function offload_pre_check() will return false, so not offload. This is a special case that can be handled safely. Therefore, modify to let initial packet which won't go through conntrack can be offloaded, as long as the cared ct fields are all zero.

Introduce a simple helper function to replace a common pattern. When accessing the GRO header, we fetch the pointer from frag0, then test its validity and fetch it from the skb when necessary. This leads to the pattern skb_gro_header_fast -> skb_gro_header_hard -> skb_gro_header_slow recurring many times throughout GRO code. This patch replaces these patterns with a single inlined function call, improving code readability. Signed-off-by:

Joanne Koong says: ==================== Add a second bind table hashed by port and address Currently, there is one bind hashtable (bhash) that hashes by port only. This patchset adds a second bind table (bhash2) that hashes by port and address. The motivation for adding bhash2 is to expedite bind requests in situations where the port has many sockets in its bhash table entry (eg a large number of sockets bound to different addresses on the same port), which makes checking bind conflicts costly especially given that we acquire the table entry spinlock while doing so, which can cause softirq cpu lockups and can prevent new tcp connections. We ran into this problem at Meta where the traffic team binds a large number of IPs to port 443 and the bind() call took a significant amount of time which led to cpu softirq lockups, which caused packet drops and other failures on the machine. When experimentally testing this on a local server for ~24k sockets bound to the port, the results seen were: ipv4: before - 0.002317 seconds with bhash2 - 0.000020 seconds ipv6: before - 0.002431 seconds with bhash2 - 0.000021 seconds The additions to the initial bhash2 submission [0] are: * Updating bhash2 in the cases where a socket's rcv saddr changes after it has * been bound * Adding locks for bhash2 hashbuckets [0] https://lore.kernel.org/netdev/20220520001834.2247810-1-kuba@kernel.org/ v3: https://lore.kernel.org/netdev/20220722195406.1304948-2-joannelkoong@gmail.com/ v2: https://lore.kernel.org/netdev/20220712235310.1935121-1-joannelkoong@gmail.com/ v1: https://lore.kernel.org/netdev/20220623234242.2083895-2-joannelkoong@gmail.com/ ==================== Link: https://lore.kernel.org/r/20220822181023.3979645-1-joannelkoong@gmail.comSigned-off-by:

This patch adds 2 new tests: sk_bind_sendto_listen and sk_connect_zero_addr. The sk_bind_sendto_listen test exercises the path where a socket's rcv saddr changes after it has been added to the binding tables, and then a listen() on the socket is invoked. The listen() should succeed. The sk_bind_sendto_listen test is copied over from one of syzbot's tests: https://syzkaller.appspot.com/x/repro.c?x=1673a38df00000 The sk_connect_zero_addr test exercises the path where the socket was never previously added to the binding tables and it gets assigned a saddr upon a connect() to address 0.

This test populates the bhash table for a given port with MAX_THREADS * MAX_CONNECTIONS sockets, and then times how long a bind request on the port takes. When populating the bhash table, we create the sockets and then bind the sockets to the same address and port (SO_REUSEADDR and SO_REUSEPORT are set). When timing how long a bind on the port takes, we bind on a different address without SO_REUSEPORT set. We do not set SO_REUSEPORT because we are interested in the case where the bind request does not go through the tb->fastreuseport path, which is fragile (eg tb->fastreuseport path does not work if binding with a different uid). To run the script: Usage: ./bind_bhash.sh [-6 | -4] [-p port] [-a address] 6: use ipv6 4: use ipv4 port: Port number address: ip address Without any arguments, ./bind_bhash.sh defaults to ipv6 using ip address "2001:0db8:0:f101::1" on port 443. On my local machine, I see: ipv4: before - 0.002317 seconds with bhash2 - 0.000020 seconds ipv6: before - 0.002431 seconds with bhash2 - 0.000021 seconds Signed-off-by: -

The current bind hashtable (bhash) is hashed by port only. In the socket bind path, we have to check for bind conflicts by traversing the specified port's inet_bind_bucket while holding the hashbucket's spinlock (see inet_csk_get_port() and inet_csk_bind_conflict()). In instances where there are tons of sockets hashed to the same port at different addresses, the bind conflict check is time-intensive and can cause softirq cpu lockups, as well as stops new tcp connections since __inet_inherit_port() also contests for the spinlock. This patch adds a second bind table, bhash2, that hashes by port and sk->sk_rcv_saddr (ipv4) and sk->sk_v6_rcv_saddr (ipv6). Searching the bhash2 table leads to significantly faster conflict resolution and less time holding the hashbucket spinlock. Please note a few things: * There can be the case where the a socket's address changes after it has been bound. There are two cases where this happens: 1) The case where there is a bind() call on INADDR_ANY (ipv4) or IPV6_ADDR_ANY (ipv6) and then a connect() call. The kernel will assign the socket an address when it handles the connect() 2) In inet_sk_reselect_saddr(), which is called when rebuilding the sk header and a few pre-conditions are met (eg rerouting fails). In these two cases, we need to update the bhash2 table by removing the entry for the old address, and add a new entry reflecting the updated address. * The bhash2 table must have its own lock, even though concurrent accesses on the same port are protected by the bhash lock. Bhash2 must have its own lock to protect against cases where sockets on different ports hash to different bhash hashbuckets but to the same bhash2 hashbucket. This brings up a few stipulations: 1) When acquiring both the bhash and the bhash2 lock, the bhash2 lock will always be acquired after the bhash lock and released before the bhash lock is released. 2) There are no nested bhash2 hashbucket locks. A bhash2 lock is always acquired+released before another bhash2 lock is acquired+released. * The bhash table cannot be superseded by the bhash2 table because for bind requests on INADDR_ANY (ipv4) or IPV6_ADDR_ANY (ipv6), every socket bound to that port must be checked for a potential conflict. The bhash table is the only source of port->socket associations. Signed-off-by:

mlx5-updates-2022-08-22 Roi Dayan Says: =============== Add support for SF tunnel offload Mlx5 driver only supports VF tunnel offload. To add support for SF tunnel offload the driver needs to: 1. Add send-to-vport metadata matching rules like done for VFs. 2. Set an indirect table for SF vport, same as VF vport. info smaller sub functions for better maintainability. rules from esw init phase to representor load phase. SFs could be created after esw initialized and thus the send-to-vport meta rules would not be created for those SFs. By moving the creation of the rules to representor load phase we ensure creating the rules also for SFs created later. =============== Lama Kayal Says: ================ Make flow steering API loosely coupled from mlx5e_priv, in a manner to introduce more readable and maintainable modules. Make TC's private, let mlx5e_flow_steering struct be dynamically allocated, and introduce its API to maintain the code via setters and getters instead of publicly exposing it. Introduce flow steering debug macros to provide an elegant finish to the decoupled flow steering API, where errors related to flow steering shall be reported via them. All flow steering related files will drop any coupling to mlx5e_priv, instead they will get the relevant members as input. Among these, fs_tt_redirect, fs_tc, and arfs. ================
