The cited commit moved the code of mlx5e_create_tises() and changed the loop to create TISes over MLX5_MAX_PORTS constant value, instead of getting the correct lag ports supported by the device, which can cause FW errors on devices with less than MLX5_MAX_PORTS ports. Change that back to mlx5e_get_num_lag_ports(mdev). Also IPoIB interfaces create there own TISes, they don't use the eth TISes, pass a flag to indicate that. Fixes: b25bd37c ("net/mlx5: Move TISes from priv to mdev HW resources") Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>

Victor Nogueira says: ==================== net: sched: Make tc-related drop reason more flexible for remaining qdiscs This patch builds on Daniel's patch[1] to add initial support of tc drop reason. The main goal is to distinguish between policy and error drops for the remainder of the egress qdiscs (other than clsact). The drop reason is set by cls_api and act_api in the tc skb cb in case any error occurred in the data path. Also add new skb drop reasons that are idiosyncratic to TC. [1] https://lore.kernel.org/all/20231009092655.22025-1-daniel@iogearbox.net Changes in V5: - Drop "EXT_" from cookie error's drop reason name in doc Changes in V4: - Condense all the cookie drop reasons into one Changes in V3: - Removed duplicate assignment - Rename function tc_skb_cb_drop_reason to tcf_get_drop_reason - Move zone field upwards in struct tc_skb_cb to move hole to the end of the struct Changes in V2: - Dropped RFC tag - Removed check for drop reason being overwritten by filter in cls_api.c - Simplified logic and removed function tcf_init_drop_reason ==================== Signed-off-by: David S.

Incrementing on Daniel's patch[1], make tc-related drop reason more flexible for remaining qdiscs - that is, all qdiscs aside from clsact. In essence, the drop reason will be set by cls_api and act_api in case any error occurred in the data path. With that, we can give the user more detailed information so that they can distinguish between a policy drop or an error drop.

This adds support for the LED's on most chip versions. Excluded are the old non-PCIe versions and RTL8125. RTL8125 has a different LED register layout, support for it will follow later. LED's can be controlled from userspace using the netdev LED trigger. Tested on RTL8168h. Note: The driver can't know which LED's are actually physically wired. Therefore not every LED device may represent a physically available LED. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Ido Schimmel says: ==================== Add MDB bulk deletion support This patchset adds MDB bulk deletion support, allowing user space to request the deletion of matching entries instead of dumping the entire MDB and issuing a separate deletion request for each matching entry. Support is added in both the bridge and VXLAN drivers in a similar fashion to the existing FDB bulk deletion support. The parameters according to which bulk deletion can be performed are similar to the FDB ones, namely: Destination port, VLAN ID, state (e.g., "permanent"), routing protocol, source / destination VNI, destination IP and UDP port. Flushing based on flags (e.g., "offload", "fast_leave", "added_by_star_ex", "blocked") is not currently supported, but can be added in the future, if a use case arises. Patch #1 adds a new uAPI attribute to allow specifying the state mask according to which bulk deletion will be performed, if any. Patch #2 adds a new policy according to which bulk deletion requests (with 'NLM_F_BULK' flag set) will be parsed. Patches #3-#4 add a new NDO for MDB bulk deletion and invoke it from the rtnetlink code when a bulk deletion request is made. Patches #5-#6 implement the MDB bulk deletion NDO in the bridge and VXLAN drivers, respectively. Patch #7 allows user space to issue MDB bulk deletion requests by no longer rejecting the 'NLM_F_BULK' flag when it is set in 'RTM_DELMDB' requests. Patches #8-#9 add selftests for both drivers, for both good and bad flows. iproute2 changes can be found here [1]. https://github.com/idosch/iproute2/tree/submit/mdb_flush_v1 ==================== Signed-off-by: David S.

For MDB bulk delete we will need to validate 'MDBA_SET_ENTRY' differently compared to regular delete. Specifically, allow the ifindex to be zero (in case not filtering on bridge port) and force the address to be zero as bulk delete based on address is not supported. Do that by introducing a new policy and choosing the correct policy based on the presence of the 'NLM_F_BULK' flag in the netlink message header. Use nlmsg_parse() for strict validation.

Jiri Pirko says: ==================== devlink: introduce notifications filtering From: Jiri Pirko <jiri@nvidia.com> Currently the user listening on a socket for devlink notifications gets always all messages for all existing devlink instances and objects, even if he is interested only in one of those. That may cause unnecessary overhead on setups with thousands of instances present. User is currently able to narrow down the devlink objects replies to dump commands by specifying select attributes. Allow similar approach for notifications providing user a new notify-filter-set command to select attributes with values the notification message has to match. In that case, it is delivered to the socket. Note that the filtering is done per-socket, so multiple users may specify different selection of attributes with values. This patchset initially introduces support for following attributes: DEVLINK_ATTR_BUS_NAME DEVLINK_ATTR_DEV_NAME DEVLINK_ATTR_PORT_INDEX Patches #1 - #4 are preparations in devlink code, patch #3 is an optimization done on the way. Patches #5 - #7 are preparations in netlink and generic netlink code. Patch #8 is the main one in this set implementing of the notify-filter-set command and the actual per-socket filtering. Patch #9 extends the infrastructure allowing to filter according to a port index. Example: $ devlink mon port pci/0000:08:00.0/32768 [port,new] pci/0000:08:00.0/32768: type notset flavour pcisf controller 0 pfnum 0 sfnum 107 splittable false function: hw_addr 00:00:00:00:00:00 state inactive opstate detached roce enable [port,new] pci/0000:08:00.0/32768: type eth flavour pcisf controller 0 pfnum 0 sfnum 107 splittable false function: hw_addr 00:00:00:00:00:00 state inactive opstate detached roce enable [port,new] pci/0000:08:00.0/32768: type eth netdev eth3 flavour pcisf controller 0 pfnum 0 sfnum 107 splittable false function: hw_addr 00:00:00:00:00:00 state inactive opstate detached roce enable [port,new] pci/0000:08:00.0/32768: type eth netdev eth3 flavour pcisf controller 0 pfnum 0 sfnum 107 splittable false function: hw_addr 00:00:00:00:00:00 state inactive opstate detached roce enable [port,new] pci/0000:08:00.0/32768: type eth flavour pcisf controller 0 pfnum 0 sfnum 107 splittable false function: hw_addr 00:00:00:00:00:00 state inactive opstate detached roce enable [port,new] pci/0000:08:00.0/32768: type notset flavour pcisf controller 0 pfnum 0 sfnum 107 splittable false function: hw_addr 00:00:00:00:00:00 state inactive opstate detached roce enable [port,del] pci/0000:08:00.0/32768: type notset flavour pcisf controller 0 pfnum 0 sfnum 107 splittable false function: hw_addr 00:00:00:00:00:00 state inactive opstate detached roce enable ==================== Link: https://lore.kernel.org/r/20231216123001.1293639-1-jiri@resnulli.usSigned-off-by: Paolo Abeni <pabeni@redhat.com>

Alexei Starovoitov says: ==================== pull-request: bpf-next 2023-12-18 This PR is larger than usual and contains changes in various parts of the kernel. The main changes are: 1) Fix kCFI bugs in BPF, from Peter Zijlstra. End result: all forms of indirect calls from BPF into kernel and from kernel into BPF work with CFI enabled. This allows BPF to work with CONFIG_FINEIBT=y. 2) Introduce BPF token object, from Andrii Nakryiko. It adds an ability to delegate a subset of BPF features from privileged daemon (e.g., systemd) through special mount options for userns-bound BPF FS to a trusted unprivileged application. The design accommodates suggestions from Christian Brauner and Paul Moore. Example: $ sudo mkdir -p /sys/fs/bpf/token $ sudo mount -t bpf bpffs /sys/fs/bpf/token \ -o delegate_cmds=prog_load:MAP_CREATE \ -o delegate_progs=kprobe \ -o delegate_attachs=xdp 3) Various verifier improvements and fixes, from Andrii Nakryiko, Andrei Matei. - Complete precision tracking support for register spills - Fix verification of possibly-zero-sized stack accesses - Fix access to uninit stack slots - Track aligned STACK_ZERO cases as imprecise spilled registers. It improves the verifier "instructions processed" metric from single digit to 50-60% for some programs. - Fix verifier retval logic 4) Support for VLAN tag in XDP hints, from Larysa Zaremba. 5) Allocate BPF trampoline via bpf_prog_pack mechanism, from Song Liu. End result: better memory utilization and lower I$ miss for calls to BPF via BPF trampoline. 6) Fix race between BPF prog accessing inner map and parallel delete, from Hou Tao. 7) Add bpf_xdp_get_xfrm_state() kfunc, from Daniel Xu. It allows BPF interact with IPSEC infra. The intent is to support software RSS (via XDP) for the upcoming ipsec pcpu work. Experiments on AWS demonstrate single tunnel pcpu ipsec reaching line rate on 100G ENA nics. 8) Expand bpf_cgrp_storage to support cgroup1 non-attach, from Yafang Shao. 9) BPF file verification via fsverity, from Song Liu.

It is safe to always start with imprecise SCALAR_VALUE register. Previously __mark_reg_const_zero() relied on caller to reset precise mark, but it's very error prone and we already missed it in a few places. So instead make __mark_reg_const_zero() reset precision always, as it's a safe default for SCALAR_VALUE. Explanation is basically the same as for why we are resetting (or rather not setting) precision in current state. If necessary, precision propagation will set it to precise correctly. As such, also remove a big comment about forward precision propagation in mark_reg_stack_read() and avoid unnecessarily setting precision to true after reading from STACK_ZERO stack. Again, precision propagation will correctly handle this, if that SCALAR_VALUE register will ever be needed to be precise.

Donald Hunter says: ==================== tools/net/ynl: Add 'sub-message' support to ynl This patchset adds a 'sub-message' attribute type to the netlink-raw schema and implements it in ynl. This provides support for kind-specific options attributes as used in rt_link and tc raw netlink families. A description of the new 'sub-message' attribute type and the corresponding sub-message definitions is provided in patch 3. The patchset includes updates to the rt_link spec and a new tc spec that make use of the new 'sub-message' attribute type. As mentioned in patch 4, encode support is not yet implemented in ynl and support for sub-message selectors at a different nest level from the key attribute is not yet supported. I plan to work on these in follow-up patches. Patches 1 is code cleanup in ynl Patches 2-4 add sub-message support to the schema and ynl with documentation updates. Patch 5 adds binary and pad support to structs in netlink-raw. Patches 6-8 contain specs that use the sub-message attribute type. Patches 9-13 update ynl-gen-rst and its make target ==================== Link: https://lore.kernel.org/r/20231215093720.18774-1-donald.hunter@gmail.comSigned-off-by: Jakub Kicinski <kuba@kernel.org>
