Currently the jails are not are stopped in reverse order which may break dependencies between jails/services and prevent a clean shutdown. The new parameter "jail_reverse_stop" will shutdown jails in "jail_list" in reverse order when set to "YES". Please note that this does not affect manual invocation of the jail rc script.

| | | | | | | | | | | | | | | | | nvd: add hw.nvd.delete_max tunable The NVMe specification does not define a maximum or optimal delete size, so technically max delete size is min(full size of namespace, 2^32 - 1 LBAs). A single delete operation for a multi-TB NVMe namespace though may take much longer to complete than the nvme(4) I/O timeout period. So choose a sensible default here that is still suitably large to minimize the number of overall delete operations. This also fixes possible uint32_t overflow on initial TRIM operation for zpool create operations for NVMe namespaces with >4G LBAs. Approved by: re (glebius) Sponsored by: Intel

The changes in r287442 required some reworking since the 'fo_fill_kinfo' file op does not exist in stable/10. 287442: Detect badly behaved coredump note helpers Coredump notes depend on being able to invoke dump routines twice; once in a dry-run mode to get the size of the note, and another to actually emit the note to the corefile. When a note helper emits a different length section the second time around than the length it requested the first time, the kernel produces a corrupt coredump. NT_PROCSTAT_FILES output length, when packing kinfo structs, is tied to the length of filenames corresponding to vnodes in the process' fd table via vn_fullpath. As vnodes may move around during dump, this is racy. So: - Detect badly behaved notes in putnote() and pad underfilled notes. - Add a fail point, debug.fail_point.fill_kinfo_vnode__random_path to exercise the NT_PROCSTAT_FILES corruption. It simply picks random lengths to expand or truncate paths to in fo_fill_kinfo_vnode(). - Add a sysctl, kern.coredump_pack_fileinfo, to allow users to disable kinfo packing for PROCSTAT_FILES notes. This should avoid both FILES note corruption and truncation, even if filenames change, at the cost of about 1 kiB in padding bloat per open fd. Document the new sysctl in core.5. - Fix note_procstat_files to self-limit in the 2nd pass. Since sometimes this will result in a short write, pad up to our advertised size. This addresses note corruption, at the risk of sometimes truncating the last several fd info entries. - Fix NT_PROCSTAT_FILES consumers libutil and libprocstat to grok the zero padding. 287537: Follow-up to r287442: Move sysctl to compiled-once file Avoid duplicate sysctl nodes. 288944: Fix core corruption caused by race in note_procstat_vmmap This fix is spiritually similar to r287442 and was discovered thanks to the KASSERT added in that revision. NT_PROCSTAT_VMMAP output length, when packing kinfo structs, is tied to the length of filenames corresponding to vnodes in the process' vm map via vn_fullpath. As vnodes may move during coredump, this is racy. We do not remove the race, only prevent it from causing coredump corruption. - Add a sysctl, kern.coredump_pack_vmmapinfo, to allow users to disable kinfo packing for PROCSTAT_VMMAP notes. This avoids VMMAP corruption and truncation, even if names change, at the cost of up to PATH_MAX bytes per mapped object. The new sysctl is documented in core.5. - Fix note_procstat_vmmap to self-limit in the second pass. This addresses corruption, at the cost of sometimes producing a truncated result. - Fix PROCSTAT_VMMAP consumers libutil (and libprocstat, via copy-paste) to grok the new zero padding.
