2024-03-01net/mlx5: Check capability for fw_resetMoshe Shemesh1-1/+3
Functions which can't access MFRL (Management Firmware Reset Level) register, have no use of fw_reset structures or events. Remove fw_reset structures allocation and registration for fw reset events notifications for these functions. Having the devlink param enable_remote_dev_reset on functions that don't have this capability is misleading as these functions are not allowed to influence the reset flow. Hence, this patch removes this parameter for such functions. In addition, return not supported on devlink reload action fw_activate for these functions.

2024-01-24net/mlx5e: Use the correct lag ports number when creating TISesSaeed Mahameed1-0/+1
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. This fixes the following errors that might appear in kernel log: mlx5_cmd_out_err:808:(pid 650): CREATE_TIS(0x912) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0x595b5d), err(-22) mlx5e_create_mdev_resources:174:(pid 650): alloc tises failed, -22 Fixes: b25bd37c859f ("net/mlx5: Move TISes from priv to mdev HW resources") Signed-off-by: Saeed Mahameed <[email protected]>

https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next 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 allows BPF progs get fsverity digest. * tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (164 commits) bpf: Ensure precise is reset to false in __mark_reg_const_zero() selftests/bpf: Add more uprobe multi fail tests bpf: Fail uprobe multi link with negative offset selftests/bpf: Test the release of map btf s390/bpf: Fix indirect trampoline generation selftests/bpf: Temporarily disable dummy_struct_ops test on s390 x86/cfi,bpf: Fix bpf_exception_cb() signature bpf: Fix dtor CFI cfi: Add CFI_NOSEAL() x86/cfi,bpf: Fix bpf_struct_ops CFI x86/cfi,bpf: Fix bpf_callback_t CFI x86/cfi,bpf: Fix BPF JIT call cfi: Flip headers selftests/bpf: Add test for abnormal cnt during multi-kprobe attachment selftests/bpf: Don't use libbpf_get_error() in kprobe_multi_test selftests/bpf: Add test for abnormal cnt during multi-uprobe attachment bpf: Limit the number of kprobes when attaching program to multiple kprobes bpf: Limit the number of uprobes when attaching program to multiple uprobes bpf: xdp: Register generic_kfunc_set with XDP programs selftests/bpf: utilize string values for delegate_xxx mount options ... ==================== Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>

2023-12-13net/mlx5: Move TISes from priv to mdev HW resourcesTariq Toukan1-0/+2
The transport interface send (TIS) object is responsible for performing all transport related operations of the transmit side. Messages from Send Queues get segmented and transmitted by the TIS including all transport required implications, e.g. in the case of large send offload, the TIS is responsible for the segmentation. These are stateless objects and can be used by multiple netdevs (e.g. representors) who share the same core device. Providing the TISes as a service from the core layer to the netdev layer reduces the number of replecated TIS objects (in case of multiple netdevs), and will ease the transition to netdev with multiple mdevs. Signed-off-by: Tariq Toukan <[email protected]> Reviewed-by: Gal Pressman <[email protected]> Signed-off-by: Saeed Mahameed <[email protected]>
