[PATCH bpf-next 0/2] selftests/bpf: Move test_lwt_seg6local to test_progs

by Bastien Curutchet (eBPF Foundation)

Hi all, This patch series continues the work to migrate the script tests into prog_tests. test_lwt_seg6local.sh tests some bpf_lwt_* helpers. It contains only one test that uses a network topology quite different than the ones that can be found in others prog_tests/lwt_*.c files so I add a new prog_tests/lwt_seg6local.c file. While working on the migration I noticed that some routes present in the script weren't needed so PATCH 1 deletes them and then PATCH 2 migrates the test into the test_progs framework.

[PATCH v5 bpf-next 0/2] security: Propagate caller information in bpf hooks

by Blaise Boscaccy

Hello, While trying to implement an eBPF gatekeeper program, we ran into an issue whereas the LSM hooks are missing some relevant data. Certain subcommands passed to the bpf() syscall can be invoked from either the kernel or userspace. Additionally, some fields in the bpf_attr struct contain pointers, and depending on where the subcommand was invoked, they could point to either user or kernel memory. One example of this is the bpf_prog_load subcommand and its fd_array. This data is made available and used by the verifier but not made available to the LSM subsystem. This patchset simply exposes that information to applicable LSM hooks. Change list: - v4 -> v5 - merge v4 selftest breakout patch back into a single patch - change "is_kernel" to "kernel" - add selftest using new kernel flag - v3 -> v4 - split out selftest changes into a separate patch - v2 -> v3 - reorder params so that the new boolean flag is the last param - fixup function signatures in bpf selftests - v1 -> v2 - Pass a boolean flag in lieu of bpfptr_t Revisions: - v4 https://lore.kernel.org/bpf/20250304203123.3935371-1-bboscaccy@linux.micros… - v3 https://lore.kernel.org/bpf/20250303222416.3909228-1-bboscaccy@linux.micros… - v2 https://lore.kernel.org/bpf/20250228165322.3121535-1-bboscaccy@linux.micros… - v1 https://lore.kernel.org/bpf/20250226003055.1654837-1-bboscaccy@linux.micros… Blaise Boscaccy (2): security: Propagate caller information in bpf hooks selftests/bpf: Add a kernel flag test for LSM bpf hook include/linux/lsm_hook_defs.h | 6 +-- include/linux/security.h | 12 +++--- kernel/bpf/syscall.c | 10 ++--- security/security.c | 15 ++++--- security/selinux/hooks.c | 6 +-- .../selftests/bpf/prog_tests/kernel_flag.c | 43 +++++++++++++++++++ .../selftests/bpf/progs/rcu_read_lock.c | 3 +- .../bpf/progs/test_cgroup1_hierarchy.c | 4 +- .../selftests/bpf/progs/test_kernel_flag.c | 32 ++++++++++++++ .../bpf/progs/test_kfunc_dynptr_param.c | 6 +-- .../selftests/bpf/progs/test_lookup_key.c | 2 +- .../selftests/bpf/progs/test_ptr_untrusted.c | 2 +- .../bpf/progs/test_task_under_cgroup.c | 2 +- .../bpf/progs/test_verify_pkcs7_sig.c | 2 +- 14 files changed, 112 insertions(+), 33 deletions(-) create mode 100644 tools/testing/selftests/bpf/prog_tests/kernel_flag.c create mode 100644 tools/testing/selftests/bpf/progs/test_kernel_flag.c -- 2.48.1

[PATCH net-next v8 0/6] tun: Introduce virtio-net hashing feature

by Akihiko Odaki

virtio-net have two usage of hashes: one is RSS and another is hash reporting. Conventionally the hash calculation was done by the VMM. However, computing the hash after the queue was chosen defeats the purpose of RSS. Another approach is to use eBPF steering program. This approach has another downside: it cannot report the calculated hash due to the restrictive nature of eBPF. Introduce the code to compute hashes to the kernel in order to overcome thse challenges. An alternative solution is to extend the eBPF steering program so that it will be able to report to the userspace, but it is based on context rewrites, which is in feature freeze. We can adopt kfuncs, but they will not be UAPIs. We opt to ioctl to align with other relevant UAPIs (KVM and vhost_net). The patches for QEMU to use this new feature was submitted as RFC and is available at: https://patchew.org/QEMU/20240915-hash-v3-0-79cb08d28647@daynix.com/ This work was presented at LPC 2024: https://lpc.events/event/18/contributions/1963/ V1 -> V2: Changed to introduce a new BPF program type.

[PATCH v2 net 0/6] eth: bnxt: fix several bugs in the bnxt module

by Taehee Yoo

The first fixes setting incorrect skb->truesize. When xdp-mb prog returns XDP_PASS, skb is allocated and initialized. Currently, The truesize is calculated as BNXT_RX_PAGE_SIZE * sinfo->nr_frags, but sinfo->nr_frags is flushed by napi_build_skb(). So, it stores sinfo before calling napi_build_skb() and then use it for calculate truesize. The second fixes kernel panic in the bnxt_queue_mem_alloc(). The bnxt_queue_mem_alloc() accesses rx ring descriptor. rx ring descriptors are allocated when the interface is up and it's freed when the interface is down. So, if bnxt_queue_mem_alloc() is called when the interface is down, kernel panic occurs. This patch makes the bnxt_queue_mem_alloc() return -ENETDOWN if rx ring descriptors are not allocated. The third patch fixes kernel panic in the bnxt_queue_{start | stop}(). When a queue is restarted bnxt_queue_{start | stop}() are called. These functions set MRU to 0 to stop packet flow and then to set up the remaining things. MRU variable is a member of vnic_info[] the first vnic_info is for default and the second is for ntuple. The first vnic_info is always allocated when interface is up, but the second is allocated only when ntuple is enabled. (ethtool -K eth0 ntuple <on | off>). Currently, the bnxt_queue_{start | stop}() access vnic_info[BNXT_VNIC_NTUPLE] regardless of whether ntuple is enabled or not. So kernel panic occurs. This patch make the bnxt_queue_{start | stop}() use bp->nr_vnics instead of BNXT_VNIC_NTUPLE. The fourth patch fixes a warning due to checksum state. The bnxt_rx_pkt() checks whether skb->ip_summed is not CHECKSUM_NONE before updating ip_summed. if ip_summed is not CHECKSUM_NONE, it WARNS about it. However, the bnxt_xdp_build_skb() is called in XDP-MB-PASS path and it updates ip_summed earlier than bnxt_rx_pkt(). So, in the XDP-MB-PASS path, the bnxt_rx_pkt() always warns about checksum. Updating ip_summed at the bnxt_xdp_build_skb() is unnecessary and duplicate, so it is removed. The fifth patch makes net_devmem_unbind_dmabuf() ignore -ENETDOWN. When devmem socket is closed, net_devmem_unbind_dmabuf() is called to unbind/release resources. If interface is down, the driver returns -ENETDOWN. The -ENETDOWN return value is not an actual error, because the interface will release resources when the interface is down. So, net_devmem_unbind_dmabuf() needs to ignore -ENETDOWN. The last patch adds XDP testcases to tools/testing/selftests/drivers/net/ping.py. v2: - Do not use num_frags in the bnxt_xdp_build_skb(). (1/6) - Add Review tags from Somnath and Jakub. (2/6) - Add new patch for fixing checksum warning. (4/6) - Add new patch for fixing warning in net_devmem_unbind_dmabuf().
