selftests: net: test for lwtunnel dst ref loops

2025-03-20T10:25:52Z

As recently specified by commit 0ea09cbf8350 ("docs: netdev: add a note on selftest posting") in net-next, the selftest is therefore shipped in this series. However, this selftest does not really test this series. It needs this series to avoid crashing the kernel. What it really tests, thanks to kmemleak, is what was fixed by the following commits: - commit c71a192976de ("net: ipv6: fix dst refleaks in rpl, seg6 and ioam6 lwtunnels") - commit 92191dd10730 ("net: ipv6: fix dst ref loops in rpl, seg6 and ioam6 lwtunnels") - commit c64a0727f9b1 ("net: ipv6: fix dst ref loop on input in seg6 lwt") - commit 13e55fbaec17 ("net: ipv6: fix dst ref loop on input in rpl lwt") - commit 0e7633d7b95b ("net: ipv6: fix dst ref loop in ila lwtunnel") - commit 5da15a9c11c1 ("net: ipv6: fix missing dst ref drop in ila lwtunnel") Signed-off-by: Justin Iurman Link: https://patch.msgid.link/20250314120048.12569-4-justin.iurman@uliege.be Signed-off-by: Paolo Abeni

selftests/mm: run_vmtests.sh: fix half_ufd_size_MB calculation

2025-03-17T00:40:25Z

We noticed that uffd-stress test was always failing to run when invoked for the hugetlb profiles on x86_64 systems with a processor count of 64 or bigger: ... # ------------------------------------ # running ./uffd-stress hugetlb 128 32 # ------------------------------------ # ERROR: invalid MiB (errno=9, @uffd-stress.c:459) ... # [FAIL] not ok 3 uffd-stress hugetlb 128 32 # exit=1 ... The problem boils down to how run_vmtests.sh (mis)calculates the size of the region it feeds to uffd-stress. The latter expects to see an amount of MiB while the former is just giving out the number of free hugepages halved down. This measurement discrepancy ends up violating uffd-stress' assertion on number of hugetlb pages allocated per CPU, causing it to bail out with the error above. This commit fixes that issue by adjusting run_vmtests.sh's half_ufd_size_MB calculation so it properly renders the region size in MiB, as expected, while maintaining all of its original constraints in place.

selftests: Add IPv6 link-local address generation tests for GRE devices.

2025-03-13T09:17:42Z

GRE devices have their special code for IPv6 link-local address generation that has been the source of several regressions in the past. Add selftest to check that all gre, ip6gre, gretap and ip6gretap get an IPv6 link-link local address in accordance with the net.ipv6.conf..addr_gen_mode sysctl.
