infiniband/core/ib_addr.c: fix typo

2026-07-09T15:41:50Z

We should exit the net epoch instead of acquiring one more entry. Reported by: Wafa Hamzah Reviewed by: jhb Sponsored by: Nvidia networking Fixes: 4726b80d9379 ("OFED: Various changes from Linux 4.20") Differential revision: https://reviews.freebsd.org/D58127

ofed/ib_uverbs: release rdma_user_mmap entry ref in rdma_umap_close()

2026-07-07T11:25:23Z

Import Linux upstream commit 3411f9f01b76bd88aa6e0e013847ab6479cb4f24. rdma_umap_priv_init() takes a reference on the rdma_user_mmap entry for every VMA it maps, but rdma_umap_close() never dropped it. The entry was therefore never freed and lingered in ucontext->mmap_xa, tripping WARN_ON(!xa_empty(&ucontext->mmap_xa)) at context teardown and leaking the firmware UAR on every context close.

mlx5: extend mlx5_ib_create_cq struct with fields from the current Linux ABI

2026-07-07T11:24:11Z

This is backward ABI-compatible, because the only place in kernel that uses the structure, namely the mlx5_ib_cq.c:mlx5_ib_create_cq() function, copies in as much structure members as provided by userspace. Tested by: Wafa Hamzah Sponsored by: Nvidia networking MFC after: 1 month

ibcore: Fix GID sysctl fallback formatting

2026-07-06T10:15:02Z

When a GID table entry is empty or not yet present in the cache, show_port_gid() falls back to printing a zero GID. Use the existing GID_PRINT_FMT/GID_PRINT_ARGS helpers instead of Linux's %pI6 format, which FreeBSD printf treats as a pointer followed by "I6". This makes empty GID sysctl entries consistently report 0000:0000:0000:0000:0000:0000:0000:0000.

OFED: Various changes from Linux 4.19

2026-06-24T19:30:56Z

Many of these changes deal with shifting from fetcing SGID attributes via an index in drivers to including references to SGID attributes in other structures passed to driver callbacks which can be used directly avoiding the need for fetching attributes via lookup functions. I had to fixup the ROCE GID management code directly as the version in FreeBSD is very different from Linux. I also tweaked the change from commit 475c8de7bf2dc86d9806709a04e9c8f524d4ec32 to use a goto to reduce diffs with upstream to minimize conflicts when merging upstream changes.
