selftests: nft_queue.sh: add a parallel stress test

2026-04-08T11:34:51Z

Introduce a new stress test to check for race conditions in the nfnetlink_queue subsystem, where an entry is freed while another CPU is concurrently walking the global rhashtable. To trigger this, `nf_queue.c` is extended with two new flags: * -O (out-of-order): Buffers packet IDs and flushes them in reverse. * -b (bogus verdicts): Floods the kernel with non-existent packet IDs. The bogus verdict loop forces the kernel's lookup function to perform full rhashtable bucket traversals (-ENOENT). Combined with reverse-order flushing and heavy parallel UDP/ping flooding across 8 queues, this puts the nfnetlink_queue code under pressure. Joint work with Florian Westphal.

selftests: seg6: add test for dst_cache isolation in seg6 lwtunnel

2026-04-08T03:20:56Z

Add a selftest that verifies the dst_cache in seg6 lwtunnel is not shared between the input (forwarding) and output (locally generated) paths. The test creates three namespaces (ns_src, ns_router, ns_dst) connected in a line. An SRv6 encap route on ns_router encapsulates traffic destined to cafe::1 with SID fc00::100. The SID is reachable only for forwarded traffic (from ns_src) via an ip rule matching the ingress interface (iif veth-r0 lookup 100), and blackholed in the main table. The test verifies that: 1. A packet generated locally on ns_router does not reach ns_dst with an empty cache, since the SID is blackholed; 2. A forwarded packet from ns_src populates the input cache from table 100 and reaches ns_dst; 3. A packet generated locally on ns_router still does not reach ns_dst after the input cache is populated, confirming the output path does not reuse the input cache entry. Both the forwarded and local packets are pinned to the same CPU with taskset, since dst_cache is per-cpu.

selftests: net: bridge_vlan_mcast: wait for h1 before querier check

2026-04-08T03:16:16Z

The querier-interval test adds h1 (currently a slave of the VRF created by simple_if_init) to a temporary bridge br1 acting as an outside IGMP querier. The kernel VRF driver (drivers/net/vrf.c) calls cycle_netdev() on every slave add and remove, toggling the interface admin-down then up. Phylink takes the PHY down during the admin-down half of that cycle. Since h1 and swp1 are cable-connected, swp1 also loses its link may need several seconds to re-negotiate. Use setup_wait_dev $h1 0 which waits for h1 to return to UP state, so the test can rely on the link being back up at this point.

selftests: bpf: adjust rx_dropped xskxceiver's test to respect tailroom

2026-04-07T01:43:52Z

Since we have changed how big user defined headroom in umem can be, change the logic in testapp_stats_rx_dropped() so we pass updated headroom validation in xdp_umem_reg() and still drop half of frames. Test works on non-mbuf setup so __xsk_pool_get_rx_frame_size() that is called on xsk_rcv_check() will not account skb_shared_info size. Taking the tailroom size into account in test being fixed is needed as xdp_umem_reg() defaults to respect it.

selftests: bpf: have a separate variable for drop test

2026-04-07T01:43:52Z

Currently two different XDP programs share a static variable for different purposes (picking where to redirect on shared umem test & whether to drop a packet). This can be a problem when running full test suite - idx can be written by shared umem test and this value can cause a false behavior within XDP drop half test. Introduce a dedicated variable for drop half test so that these two don't step on each other toes. There is no real need for using __sync_fetch_and_add here as XSK tests are executed on single CPU.

selftests: bpf: fix pkt grow tests

2026-04-07T01:43:51Z

Skip tail adjust tests in xskxceiver for SKB mode as it is not very friendly for it. multi-buffer case does not work as xdp_rxq_info that is registered for generic XDP does not report ::frag_size. The non-mbuf path copies packet via skb_pp_cow_data() which only accounts for headroom, leaving us with no tailroom and causing underlying XDP prog to drop packets therefore. For multi-buffer test on other modes, change the amount of bytes we use for growth, assume worst-case scenario and take care of headroom and tailroom.

selftests: bpf: introduce a common routine for reading procfs

2026-04-07T01:43:51Z

Parametrize current way of getting MAX_SKB_FRAGS value from {sys,proc}fs so that it can be re-used to get cache line size of system's CPU. All that just to mimic and compute size of kernel's struct skb_shared_info which for xsk and test suite interpret as tailroom. Introduce two variables to ifobject struct that will carry count of skb frags and tailroom size. Do the reading and computing once, at the beginning of test suite execution in xskxceiver, but for test_progs such way is not possible as in this environment each test setups and torns down ifobject structs.
