Change devlink instance locks in mlx5 driver to have devlink reload callbacks locked, while keeping all driver paths which lead to devl_ API functions called by the driver locked. Add mlx5_load_one_devl_locked() and mlx5_unload_one_devl_locked() which are used by the paths which are already locked such as devlink reload callbacks. This patch makes the driver use devl_ API also for traps register as these functions are called from the driver paths parallel to reload that requires locking now. Signed-off-by:

Refactor fw reset code to have the unload driver part done on mlx5_fw_reset_complete_reload(), so if it was called by the PF which initiated the reload fw activate flow, the unload part will be handled by the mlx5_devlink_reload_fw_activate() callback itself and not by the reset event work. This will be used by the downstream patch to invoke devlink reload callbacks with devlink lock held. Signed-off-by:

After mlx4 driver is converted to do locked reload, devlink_region_snapshot_create() may be called from both locked and unlocked context. Note that in mlx4 region snapshots could be created on any command failure. That can happen in any flow that involves commands to FW, which means most of the driver flows. So resolve this by removing dependency on devlink->lock for region snapshots list consistency and introduce new mutex to ensure it. Signed-off-by:

So resolve this by removing dependency on devlink->lock for region snapshot ID tracking by using internal xa_lock() to maintain shapshot_ids xa_array consistency. Signed-off-by:

Add a framework for running selftests. Framework exposes devlink commands and test suite(s) to the user to execute and query the supported tests by the driver. Below are new entries in devlink_nl_ops devlink_nl_cmd_selftests_show_doit/dumpit: To query the supported selftests by the drivers. devlink_nl_cmd_selftests_run: To execute selftests. Users can provide a test mask for executing group tests or standalone tests. Documentation/networking/devlink/ path is already part of MAINTAINERS & the new files come under this path.

Tariq Toukan says: ==================== mlx5e use TLS TX pool to improve connection rate To offload encryption operations, the mlx5 device maintains state and keeps track of every kTLS device-offloaded connection. Two HW objects are used per TX context of a kTLS offloaded connection: a. Transport interface send (TIS) object, to reach the HW context. b. Data Encryption Key (DEK) to perform the crypto operations. These two objects are created and destroyed per TLS TX context, via FW commands. In total, 4 FW commands are issued per TLS TX context, which seriously limits the connection rate. In this series, we aim to save creation and destroy of TIS objects by recycling them. Upon recycling of a TIS, the HW still needs to be notified for the re-mapping between a TIS and a context. This is done by posting WQEs via an SQ, significantly faster API than the FW command interface. A pool is used for recycling. The pool dynamically interacts to the load and connection rate, growing and shrinking accordingly. Saving the TIS FW commands per context increases connection rate by ~42%, from 11.6K to 16.5K connections per sec. Connection rate is still limited by FW bottleneck due to the remaining per context FW commands (DEK create/destroy). This will soon be addressed in a followup series. By combining the two series, the FW bottleneck will be released, and a significantly higher (about 100K connections per sec) kTLS TX device-offloaded connection rate is reached. ==================== Link: https://lore.kernel.org/r/20220727094346.10540-1-tariqt@nvidia.comSigned-off-by:

Let the TLS TX recycle pool be more flexible in size, by continuously and dynamically allocating and releasing HW resources in response to changes in the connections rate and load. Allocate and release pool entries in bulks (16). Use a workqueue to release/allocate in the background. Allocate a new bulk when the pool size goes lower than the low threshold (1K). Symmetric operation is done when the pool size gets greater than the upper threshold (4K). Every idle pool entry holds: 1 TIS, 1 DEK (HW resources), in addition to ~100 bytes in host memory. Start with an empty pool to minimize memory and HW resources waste for non-TLS users that have the device-offload TLS enabled. Upon a new request, in case the pool is empty, do not wait for a whole bulk allocation to complete. Instead, trigger an instant allocation of a single resource to reduce latency.

The transport interface send (TIS) object is responsible for performing all transport related operations of the transmit side. The ConnectX HW uses a TIS object to save and access the TLS crypto information and state of an offloaded TX kTLS connection. Before this patch, we used to create a new TIS per connection and destroy it once it’s closed. Every create and destroy of a TIS is a FW command. Same applies for the private TLS context, where we used to dynamically allocate and free it per connection. Resources recycling reduce the impact of the allocation/free operations and helps speeding up the connection rate. In this feature we maintain a pool of TX objects and use it to recycle the resources instead of re-creating them per connection. A cached TIS popped from the pool is updated to serve the new connection via the fast-path HW interface, updating the tls static and progress params. This is a very fast operation, significantly faster than FW commands. On recycling, a WQE fence is required after the context params change. This guarantees that the data is sent after the context has been successfully updated in hardware, and that the context modification doesn't interfere with existing traffic. Signed-off-by:

TLS TIS objects have a defined role in mapping and reaching the HW TLS contexts. Some standard TIS attributes (like LAG port affinity) are not relevant for them. Use a dedicated TLS TIS create function instead of the generic mlx5e_create_tis. Signed-off-by:

Multiple TLS device-offloaded contexts can be added in parallel via concurrent calls to .tls_dev_add, while calls to .tls_dev_del are sequential in tls_device_gc_task. This is not a sustainable behavior. This creates a rate gap between add and del operations (addition rate outperforms the deletion rate). When running for enough time, the TLS device resources could get exhausted, failing to offload new connections. Replace the single-threaded garbage collector work with a per-context alternative, so they can be handled on several cores in parallel. Use a new dedicated destruct workqueue for this.

TLS context destructor can be run in atomic context. Cleanup operations for device-offloaded contexts could require access and interaction with the device callbacks, which might sleep. Hence, the cleanup of such contexts must be deferred and completed inside an async work. For all others, this is not necessary, as cleanup is atomic. Invoke cleanup immediately for them, avoiding queueing redundant gc work. Signed-off-by:

I went too far in the accessor conversion, we can't use tls_strp_msg() after decryption because the message may not be ready. What we care about on this path is that the output skb is detached, i.e. we didn't somehow just turn around and used the input skb with its TCP data still attached. So look at the anchor directly.

Paolo points out that there seems to be no strong reason strparser users a single threaded workqueue. Perhaps there were some performance or pinning considerations? Since we don't know (and it's the slow path) let's default to the most natural, multi-threaded choice. Also rename the workqueue to "tls-". Suggested-by:

Eric indicates that restarting rcvtimeo on every wait may be fine. I thought that we should consider it cumulative, and made tls_rx_reader_lock() return the remaining timeo after acquiring the reader lock. tls_rx_rec_wait() gets its timeout passed in by value so it does not keep track of time previously spent. Make the lock waiting consistent with tls_rx_rec_wait() - don't keep track of time spent. Read the timeo fresh in tls_rx_rec_wait(). It's unclear to me why callers are supposed to cache the value.

When we close ping6 sockets, some resources are left unfreed because pingv6_prot is missing sk->sk_prot->destroy(). As reported by syzbot [0], just three syscalls leak 96 bytes and easily cause OOM. struct ipv6_sr_hdr *hdr; char data[24] = {0}; int fd; hdr = (struct ipv6_sr_hdr *)data; hdr->hdrlen = 2; hdr->type = IPV6_SRCRT_TYPE_4; fd = socket(AF_INET6, SOCK_DGRAM, NEXTHDR_ICMP); setsockopt(fd, IPPROTO_IPV6, IPV6_RTHDR, data, 24); close(fd); To fix memory leaks, let's add a destroy function. Note the socket() syscall checks if the GID is within the range of net.ipv4.ping_group_range. The default value is [1, 0] so that no GID meets the condition (1 <= GID <= 0). Thus, the local DoS does not succeed until we change the default value. However, at least Ubuntu/Fedora/RHEL loosen it. $ cat /usr/lib/sysctl.d/50-default.conf ... -net.ipv4.ping_group_range = 0 2147483647 Also, there could be another path reported with these options, and some of them require CAP_NET_RAW. setsockopt IPV6_ADDRFORM (inet6_sk(sk)->pktoptions) IPV6_RECVPATHMTU (inet6_sk(sk)->rxpmtu) IPV6_HOPOPTS (inet6_sk(sk)->opt) IPV6_RTHDRDSTOPTS (inet6_sk(sk)->opt) IPV6_RTHDR (inet6_sk(sk)->opt) IPV6_DSTOPTS (inet6_sk(sk)->opt) IPV6_2292PKTOPTIONS (inet6_sk(sk)->opt) getsockopt IPV6_FLOWLABEL_MGR (inet6_sk(sk)->ipv6_fl_list) For the record, I left a different splat with syzbot's one. unreferenced object 0xffff888006270c60 (size 96): comm "repro2", pid 231, jiffies 4294696626 (age 13.118s) hex dump (first 32 bytes): 01 00 00 00 44 00 00 00 00 00 00 00 00 00 00 00 ....D........... 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<00000000f6bc7ea9>] sock_kmalloc (net/core/sock.c:2564 net/core/sock.c:2554) [<000000006d699550>] do_ipv6_setsockopt.constprop.0 (net/ipv6/ipv6_sockglue.c:715) [<00000000c3c3b1f5>] ipv6_setsockopt (net/ipv6/ipv6_sockglue.c:1024) [<000000007096a025>] __sys_setsockopt (net/socket.c:2254) [<000000003a8ff47b>] __x64_sys_setsockopt (net/socket.c:2265 net/socket.c:2262 net/socket.c:2262) [<000000007c409dcb>] do_syscall_64 (arch/x86/entry/common.c:50 arch/x86/entry/common.c:80) [<00000000e939c4a9>] entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:120) [0]: https://syzkaller.appspot.com/bug?extid=a8430774139ec3ab7176 Fixes: 6d0bfe22 ("net: ipv6: Add IPv6 support to the ping socket.")

If a watch is being added to a queue, it needs to guard against interference from addition of a new watch, manual removal of a watch and removal of a watch due to some other queue being destroyed. KEYCTL_WATCH_KEY guards against this for the same {key,queue} pair by holding the key->sem writelocked and by holding refs on both the key and the queue - but that doesn't prevent interaction from other {key,queue} pairs. While add_watch_to_object() does take the spinlock on the event queue, it doesn't take the lock on the source's watch list. The assumption was that the caller would prevent that (say by taking key->sem) - but that doesn't prevent interference from the destruction of another queue. Fix this by locking the watcher list in add_watch_to_object().

It is OK for XDP_TX but the same code is used by ndo_xdp_xmit. In that case it loses the XDP memory type and releases the packet incorrectly for some of the types. Assorted breakage follows.

Commit 3c783b83 ("net: dsa: mv88e6xxx: get rid of SPEED_MAX setting") stopped relying on SPEED_MAX constant and hardcoded speed settings for the switch ports and rely on phylink configuration. It turned out, however, that when the relevant code is called, the mac_capabilites of CPU/DSA port remain unset. mv88e6xxx_setup_port() is called via mv88e6xxx_setup() in dsa_tree_setup_switches(), which precedes setting the caps in phylink_get_caps down in the chain of dsa_tree_setup_ports(). As a result the mac_capabilites are 0 and the default speed for CPU/DSA port is 10M at the start. To fix that, execute mv88e6xxx_get_caps() and obtain the capabilities driectly.

A NULL pointer dereference was reported by Wei Chen: BUG: kernel NULL pointer dereference, address: 0000000000000000 RIP: 0010:__list_del_entry_valid+0x26/0x80 Call Trace: <TASK> sctp_sched_dequeue_common+0x1c/0x90 sctp_sched_prio_dequeue+0x67/0x80 __sctp_outq_teardown+0x299/0x380 sctp_outq_free+0x15/0x20 sctp_association_free+0xc3/0x440 sctp_do_sm+0x1ca7/0x2210 sctp_assoc_bh_rcv+0x1f6/0x340 This happens when calling sctp_sendmsg without connecting to server first. In this case, a data chunk already queues up in send queue of client side when processing the INIT_ACK from server in sctp_process_init() where it calls sctp_stream_init() to alloc stream_in. If it fails to alloc stream_in all stream_out will be freed in sctp_stream_init's err path. Then in the asoc freeing it will crash when dequeuing this data chunk as stream_out is missing. As we can't free stream out before dequeuing all data from send queue, and this patch is to fix it by moving the err path stream_out/in freeing in sctp_stream_init() to sctp_stream_free() which is eventually called when freeing the asoc in sctp_association_free(). This fix also makes the code in sctp_process_init() more clear. Note that in sctp_association_init() when it fails in sctp_stream_init(), sctp_association_free() will not be called, and in that case it should go to 'stream_free' err path to free stream instead of 'fail_init'.
