selftests: net: add a test for closing a netlink socket ith dump in progress

2024-11-07T21:45:34Z

Close a socket with dump in progress. We need a dump which generates enough info not to fit into a single skb. Policy dump fits the bill. Use the trick discovered by syzbot for keeping a ref on the socket longer than just close, with mqueue. TAP version 13 1..3 # Starting 3 tests from 1 test cases. # RUN global.test_sanity ... # OK global.test_sanity ok 1 global.test_sanity # RUN global.close_in_progress ... # OK global.close_in_progress ok 2 global.close_in_progress # RUN global.close_with_ref ... # OK global.close_with_ref ok 3 global.close_with_ref # PASSED: 3 / 3 tests passed. # Totals: pass:3 fail:0 xfail:0 xpass:0 skip:0 error:0 Note that this test is not expected to fail but rather crash the kernel if we get the cleanup wrong.

Pablo Neira Ayuso says: ==================== The following patchset contains Netfilter fixes for net: 1) Remove unused parameters in conntrack_dump_flush.c used by selftests, from Liu Jing. 2) Fix possible UaF when removing xtables module via getsockopt() interface, from Dong Chenchen. 3) Fix potential crash in nf_send_reset6() reported by syzkaller. From Eric Dumazet 4) Validate offset and length before calling skb_checksum() in nft_payload, otherwise hitting BUG() is possible. netfilter pull request 24-10-31 * tag 'nf-24-10-31' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: netfilter: nft_payload: sanitize offset and length before calling skb_checksum() netfilter: nf_reject_ipv6: fix potential crash in nf_send_reset6() netfilter: Fix use-after-free in get_info() selftests: netfilter: remove unused parameter ==================== Link: https://patch.msgid.link/ Signed-off-by: Paolo Abeni

selftests: forwarding: Add IPv6 GRE remote change tests

2024-10-31T01:24:40Z

Test that after changing the remote address of an ip6gre net device traffic is forwarded as expected. Test with both flat and hierarchical topologies and with and without an input / output keys.

selftests: netfilter: nft_flowtable.sh: make first pass deterministic

2024-10-29T18:26:09Z

The CI occasionaly encounters a failing test run. Example: # PASS: ipsec tunnel mode for ns1/ns2 # re-run with random mtus: -o 10966 -l 19499 -r 31322 # PASS: flow offloaded for ns1/ns2 [..] # FAIL: ipsec tunnel ... counter 1157059 exceeds expected value 878489 This script will re-exec itself, on the second run, random MTUs are chosen for the involved links. This is done so we can cover different combinations (large mtu on client, small on server, link has lowest mtu, etc). Furthermore, file size is random, even for the first run. Rework this script and always use the same file size on initial run so that at least the first round can be expected to have reproducible behavior. Second round will use random mtu/filesize. Raise the failure limit to that of the file size, this should avoid all errneous test errors. Currently, first fin will remove the offload, so if one peer is already closing remaining data is handled by classic path, which result in larger-than-expected counter and a test failure. Given packet path also counts tcp/ip headers, in case offload is completely broken this test will still fail (as expected). The test counter limit could be made more strict again in the future once flowtable can keep a connection in offloaded state until FINs in both directions were seen.

selftests: mptcp: list sysctl data

2024-10-28T22:50:57Z

Listing all the values linked to the MPTCP sysctl knobs was not exercised in MPTCP test suite. Let's do that to avoid any regressions, but also to have a kernel with a debug kconfig verifying more assumptions. For the moment, we are not interested by the output, only to avoid crashes and warnings.

selftests: mptcp: join: test for prohibited MPC to port-based endp

2024-10-15T17:57:02Z

Explicitly verify that MPC connection attempts towards a port-based signal endpoint fail with a reset. Note that this new test is a bit different from the other ones, not using 'run_tests'. It is then needed to add the capture capability, and the picking the right port which have been extracted into three new helpers. The info about the capture can also be printed from a single point, which simplifies the exit paths in do_transfer(). The 'Fixes' tag here below is the same as the one from the previous commit: this patch here is not fixing anything wrong in the selftests, but it validates the previous fix for an issue introduced by this commit ID.
