2023-02-06net: introduce skb_poison_list and use in kfree_skb_listJesper Dangaard Brouer
First user of skb_poison_list is in kfree_skb_list_reason, to catch bugs earlier like introduced in commit eedade12f4cb ("net: kfree_skb_list use kmem_cache_free_bulk"). For completeness mentioned bug have been fixed in commit f72ff8b81ebc ("net: fix kfree_skb_list use of skb_mark_not_on_list"). In case of a bug like mentioned commit we would have seen OOPS with: general protection fault, probably for non-canonical address 0xdead000000000870 And content of one the registers e.g. R13: dead000000000800 In this case skb->len is at offset 112 bytes (0x70) why fault happens at 0x800+0x70 = 0x870 Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: David S.

We use BH context only for synchronization, so we don't care if it's actually serving softirq or not.

2023-02-06net: bridge: Add netlink knobs for number / maximum MDB entriesPetr Machata
The previous patch added accounting for number of MDB entries per port and per port-VLAN, and the logic to verify that these values stay within configured bounds. However it didn't provide means to actually configure those bounds or read the occupancy. This patch does that. Two new netlink attributes are added for the MDB occupancy: IFLA_BRPORT_MCAST_N_GROUPS for the per-port occupancy and BRIDGE_VLANDB_ENTRY_MCAST_N_GROUPS for the per-port-VLAN occupancy. And another two for the maximum number of MDB entries: IFLA_BRPORT_MCAST_MAX_GROUPS for the per-port maximum, and BRIDGE_VLANDB_ENTRY_MCAST_MAX_GROUPS for the per-port-VLAN one. Note that the two new IFLA_BRPORT_ attributes prompt bumping of RTNL_SLAVE_MAX_TYPE to size the slave attribute tables large enough. The new attributes are used like this: # ip link add name br up type bridge vlan_filtering 1 mcast_snooping 1 \ mcast_vlan_snooping 1 mcast_querier 1 # ip link set dev v1 master br # bridge vlan add dev v1 vid 2 # bridge vlan set dev v1 vid 1 mcast_max_groups 1 # bridge mdb add dev br port v1 grp 230.1.2.3 temp vid 1 # bridge mdb add dev br port v1 grp 230.1.2.4 temp vid 1 Error: bridge: Port-VLAN is already in 1 groups, and mcast_max_groups=1. # bridge link set dev v1 mcast_max_groups 1 # bridge mdb add dev br port v1 grp 230.1.2.3 temp vid 2 Error: bridge: Port is already in 1 groups, and mcast_max_groups=1. # bridge -d link show 5: v1@v2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 master br [...] [...] mcast_n_groups 1 mcast_max_groups 1 # bridge -d vlan show port vlan-id br 1 PVID Egress Untagged state forwarding mcast_router 1 v1 1 PVID Egress Untagged [...] mcast_n_groups 1 mcast_max_groups 1 2 [...] mcast_n_groups 0 mcast_max_groups 0 Signed-off-by: Petr Machata <petrm@nvidia.com> Acked-by: Nikolay Aleksandrov <razor@blackwall.org> Reviewed-by: Ido Schimmel <idosch@nvidia.com> Signed-off-by: David S.

2023-02-06net: bridge: Add a tracepoint for MDB overflowsPetr Machata
The following patch will add two more maximum MDB allowances to the global one, mcast_hash_max, that exists today. In all these cases, attempts to add MDB entries above the configured maximums through netlink, fail noisily and obviously. Such visibility is missing when adding entries through the control plane traffic, by IGMP or MLD packets. To improve visibility in those cases, add a trace point that reports the violation, including the relevant netdevice (be it a slave or the bridge itself), and the MDB entry parameters: # perf record -e bridge:br_mdb_full & # [...] # perf script | cut -d: -f4- dev v2 af 2 src ::ffff:0.0.0.0 grp ::ffff:239.1.1.112/00:00:00:00:00:00 vid 0 dev v2 af 10 src :: grp ff0e::112/00:00:00:00:00:00 vid 0 dev v2 af 2 src ::ffff:0.0.0.0 grp ::ffff:239.1.1.112/00:00:00:00:00:00 vid 10 dev v2 af 10 src 2001:db8:1::1 grp ff0e::1/00:00:00:00:00:00 vid 10 dev v2 af 2 src ::ffff:192.0.2.1 grp ::ffff:239.1.1.1/00:00:00:00:00:00 vid 10 CC: Steven Rostedt <rostedt@goodmis.org> CC: linux-trace-kernel@vger.kernel.org Signed-off-by: Petr Machata <petrm@nvidia.com> Reviewed-by: Steven Rostedt (Google) <rostedt@goodmis.org> Acked-by: Nikolay Aleksandrov <razor@blackwall.org> Signed-off-by: David S.

Some applications seem to rely on RAW sockets. If they use private netns, we can avoid piling all RAW sockets bound to a given protocol into a single bucket. Also place (struct raw_hashinfo).lock into its own cache line to limit false sharing. Alternative would be to have per-netns hashtables, but this seems too expensive for most netns where RAW sockets are not used.

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs David Howells says: ==================== Here's the fifth part of patches in the process of moving rxrpc from doing a lot of its stuff in softirq context to doing it in an I/O thread in process context and thereby making it easier to support a larger SACK table. The full description is in the description for the first part[1] which is now upstream. The second and third parts are also upstream[2]. A subset of the original fourth part[3] got applied as a fix for a race[4]. The fifth part includes some cleanups: (1) Miscellaneous trace header cleanups: fix a trace string, display the security index in rx_packet rather than displaying the type twice, remove some whitespace to make checkpatch happier and remove some excess tabulation. (2) Convert ->recvmsg_lock to a spinlock as it's only ever locked exclusively. (3) Make ->ackr_window and ->ackr_nr_unacked non-atomic as they're only used in the I/O thread. (4) Don't use call->tx_lock to access ->tx_buffer as that is only accessed inside the I/O thread. sendmsg() loads onto ->tx_sendmsg and the I/O thread decants from that to the buffer. (5) Remove local->defrag_sem as DATA packets are transmitted serially by the I/O thread. (6) Remove the service connection bundle is it was only used for its channel_lock - which has now gone. And some more significant changes: (7) Add a debugging option to allow a delay to be injected into packet reception to help investigate the behaviour over longer links than just a few cm. (8) Generate occasional PING ACKs to probe for RTT information during a receive heavy call. (9) Simplify the SACK table maintenance and ACK generation. Now that both parts are done in the same thread, there's no possibility of a race and no need to try and be cunning to avoid taking a BH spinlock whilst copying the SACK table (which in the future will be up to 2K) and no need to rotate the copy to fit the ACK packet table.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2023-01-30 Add fast update encryption key Jianbo Liu Says: ================ Data encryption keys (DEKs) are the keys used for data encryption and decryption operations. Starting from version 22.33.0783, firmware is optimized to accelerate the update of user keys into DEK object in hardware. The support for bulk allocation and destruction of DEK objects is added, and the bulk allocated DEKs are uninitialized, as the bulk creation requires no input key. When offload encryption/decryption, user gets one object from a bulk, and updates key by a new "modify DEK" command. This command is the same as create DEK object, but requires no heavy context memory allocation in firmware, which consumes most cpu cycles of the create DEK command. DEKs are cached internally by the NIC, so invalidating internal NIC caches is required before reusing DEKs. The SYNC_CRYPTO command is added to support it. DEK object can be reused, the keys in it can be updated after this command is executed. This patchset enhances the key creation and destruction flow, to get use of this new feature. Any user, for example, ktls, ipsec and macsec, can use it to offload keys. But, only ktls uses it, as others don't need many keys, and caching two many DEKs in pool is wasteful. There are two new data struts added: a. DEK pool. One pool is created for each key type. The bulks by the type, are placed in the pool's different bulk lists, according to the number of available and in_used DEKs in the bulk. b. DEK bulk. All DEKs in one bulk allocation are store here. There are two bitmaps to indicate the state of each DEK. New APIs are then added. When user need a DEK object, a. Fetch one bulk with avail DEKs, from the partial_list or avail_list, otherwise create new one. b. Pick one DEK, and set its need_sync and in_used bits to 1. Move the bulk to full_list if no more available keys, or put it to partial_list if the bulk is newly created. c. Update DEK object's key with user key, by the "modify DEK" command. d. Return DEK struct to user, then it gets the object id and fills it into the offload commands. When user free a DEK, a. Set in_use bit to 0. If all need_sync bits are 1 and all in_use bits of this bulk are 0, move it to sync_list. b. If the number of DEKs, which are freed by users, is over the threshold (128), schedule a workqueue to do the sync process. For the sync process, the SYNC_CRYPTO command is executed first. Then, for each bulks in partial_list, full_list and sync_list, reset need_sync bits of the freed DEK objects. If all need_sync bits in one bulk are zero, move it to avail_list. We already supported TIS pool to recycle the TISes. With this series and TIS pool, TLS CPS performance is improved greatly. And we tested https on the system: CPU: dual AMD EPYC 7763 64-Core processors RAM: 512G DEV: ConnectX-6 DX, with FW ver 22.33.0838 and TLS_OPTIMISE=true TLS CPS performance numbers are: Before: 11k connections/sec After: 101 connections/sec ================ * tag 'mlx5-updates-2023-01-30' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: net/mlx5e: kTLS, Improve connection rate by using fast update encryption key net/mlx5: Keep only one bulk of full available DEKs net/mlx5: Add async garbage collector for DEK bulk net/mlx5: Reuse DEKs after executing SYNC_CRYPTO command net/mlx5: Use bulk allocation for fast update encryption key net/mlx5: Add bulk allocation and modify_dek operation net/mlx5: Add support SYNC_CRYPTO command net/mlx5: Add new APIs for fast update encryption key net/mlx5: Refactor the encryption key creation net/mlx5: Add const to the key pointer of encryption key creation net/mlx5: Prepare for fast crypto key update if hardware supports it net/mlx5: Change key type to key purpose net/mlx5: Add IFC bits and enums for crypto key net/mlx5: Add IFC bits for general obj create param net/mlx5: Header file for crypto ==================== Link: https://lore.kernel.org/r/20230131031201.35336-1-saeed@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Now that general ACK transmission is done from the same thread as incoming DATA packet wrangling, there's no possibility that the SACK table will be being updated by the latter whilst the former is trying to copy it to an ACK. This means that we can safely rotate the SACK table whilst updating it without having to take a lock, rather than keeping all the bits inside it in fixed place and copying and then rotating it in the transmitter. Therefore, simplify SACK handing by keeping track of starting point in the ring and rotate slots down as we consume them.

2023-01-30devlink: remove devlink featuresJiri Pirko
Devlink features were introduced to disallow devlink reload calls of userspace before the devlink was fully initialized. The reason for this workaround was the fact that devlink reload was originally called without devlink instance lock held. However, with recent changes that converted devlink reload to be performed under devlink instance lock, this is redundant so remove devlink features entirely. Note that mlx5 used this to enable devlink reload conditionally only when device didn't act as multi port slave. Move the multi port check into mlx5_devlink_reload_down() callback alongside with the other checks preventing the device from reload in certain states.

2023-01-27devlink: protect devlink param list by instance lockJiri Pirko
Commit 1d18bb1a4ddd ("devlink: allow registering parameters after the instance") as the subject implies introduced possibility to register devlink params even for already registered devlink instance. This is a bit problematic, as the consistency or params list was originally secured by the fact it is static during devlink lifetime. So in order to protect the params list, take devlink instance lock during the params operations. Introduce unlocked function variants and use them in drivers in locked context. Put lock assertions to appropriate places.
