* rtld: free heap donelists abandoned by the lookup restartKonstantin Belousov2026-10-293-26/+67
| | | | | | | | | | | | | | | | | | | A symbol lookup done under the read-locked rtld_bind_lock is restarted with the write lock when it needs to load filtees. The restart is done by siglongjmp() from lock_restart_for_upgrade(), which skips donelist_free() for the heap donelists of the unwound frames. Only do_dlsym() freed one such donelist, tracked by SymLook.donelist_mem. The donelist of symlook_default() called from _rtld_bind(), the donelist of get_program_var_addr() called for dlopen(RTLD_TRACE), and the donelists of nested symlook_obj_load_filtees() calls were leaked. Link the heap donelists allocated under the read lock into the list owned by RtldLockState, which also owns the sigjmp_buf, instead of the symlook request.

* rc.d/mountd: Do not require /etc/exportsChristos Margiolis2026-10-071-1/+0
| | | | | | | | | | | | | | | | | | | mountd exits if it cannot read any exports files. Requiring /etc/exports, however, unconditionally stops mountd from starting on a server that exports ZFS datasets only (/etc/zfs/exports). Let sbin/mountd handle requirements itself, instead of hardcoding /etc/exports, which is also wrong, because different files can be specified in mountd_flags. This patch also works with nfsv4_server_enable="YES", by preserving the behavior of failing to start if there is no "V4:" line in the exports file, which is missing by default on ZFS-only exports.

* apmd: Retire the APM daemonJohn Baldwin2026-09-305-55/+8
| | | | | | | | | | | | | The original purpose of this daemon was to route power management requests to userspace, e.g. when the suspend button was pressed, the APM driver posted an event read by apmd(8) that would invoke zzz(8) to suspend. However, on ACPI systems this is handled by devd(8) events instead and running apmd(8) in addition just adds extra complexity. This probably should have been axed when the APM BIOS support was retired in commit 8c576a279ed5. Reviewed by: imp Differential Revision: https://reviews.freebsd.org/D59937

* rtld: more caution when parsing in digest_notes()Konstantin Belousov2026-09-141-5/+10
| | | | | | | | | | | | | | | | | | | Incorrect ELF might have PT_NOTE slightly larger than the needed to contain all notes, and the PT_NOTE size could be larger than one page. Then rtld mmaps just the notes bytes to parse. After the last note, we iterate past the mapped region trying to read the Elf_Note header. This was found in wild. Require full elf note to fit into the [start_note, end_note) region to continue the parsing. Check it in stages, first verifying the Elf_Note header structure fits, to be able to read the name and data length. After that, check the whole note against limit.

| | | | | | | | | | | | | | | | | | | This patch adds a new nfs_client_rdma_enable variable to /etc/rc.d/nfsclient to enable the client side of NFS over RDMA. The client side of NFS over RDMA requires the nfsclrdma.ko module, which is still under test/review. I wanted to get the "glue" into main so that others could test the module more easily. Avaliability of the module will be announced on freebsd-current@ soon. It should not affect non-RDMA operation. I've specified a long MFC, since the module still requires extensive testing and, hopefully, a review. MFC after: 3 months

On kernels which support run-time resizing of disks (for NVMe, this was added in November 2025; some other disk types have supported this for longer) a SIZECHANGE notification is sent to userland via devd. Add a "nostart" rc.d script (runnable manually but not automatically at boot time) and a devd script which invokes it when a notification arrives. The rc.d script enlarges the "final partition" on partitioned geoms, or the UFS filesystem or zpool device when triggered on a disk containing either of those.
