* ufshci: install the ioctl headerJaeyoon Choi2026-09-151-0/+6
| | | | | | | | | | | | | | The passthrough ioctl has a userland ABI header, but nothing installed it. A program that wanted to use the ioctl had to copy the headers out of the source tree by hand. Install ufshci.h and ufshci_ioctl.h under /usr/include/dev/ufshci, the way nvme installs nvme.h. The ioctl header pulls in ufshci.h, so both go. Add the directory to the include mtree so installworld creates it. Reviewed by: imp (mentor) Sponsored by: Samsung Electronics Differential Revision: https://reviews.freebsd.org/D59560

* gzoned: Introduce Zoned Storage emulatorvoidanix2026-09-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gzoned(8) is a new GEOM class that exposes a host-managed zoned device (similar to ZAC/ZBC drives) on top of regular, non-zoned providers. The created medium is sliced into equally sized zones, by default sequential-write-required. Such zones can be turned into conventional zones if desired. The zoned drive's state and configuration is persistent through metadata at the tail of the backing provider, meaning the zoned device gets recreated at the provider retaste. Zone state changes only mark the table dirty with BIO_FLUSH committing it, mirroring drives whose zone state is volatile until a cache flush. The new class tries to emulate real zoned drives by incorporating per-zone write pointers and support for BIO_ZONE management commands. Fault emulation through zone conditions (RWP recommended, offline, R/O), URSWRZ bit toggling and concurrent open zone limits are additional features useful for testing. While at it, fix zonectl's report of write pointer LBAs for zones that should have none, remove its forced debug flags and allow the geom(8) shared subroutines to detect host-managed drives. ATF-sh tests for gzoned(8) and zonectl(8) (dogfooded by gzoned(8)) are included, featuring helpers (see zoned_subr.sh) for testing zoned storage support in other components or GEOM classes.

* libc: Implement qualifier-preserving standard library functionsFaraz Vahedi2026-08-133-0/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | Several standard library functions are specified to return an unqualified pointer while accepting a pointer to a potentially const-qualified object. N3020 addresses this behaviour, discarding qualifiers due to incompatible pointer types, by introducing qualifier-preserving macros for the affected set of standard library functions. Add `__qualsel()` helper to `<sys/cdefs.h>`, implemented using the generic selection, and define qualifier-preserving macros for that set of functions in `<string.h>`, `<wchar.h>`, and `<stdlib.h>`. Macros are gated on `_STDC_VERSION__ >= 202311L && !__cplusplus`, therefore there is no behavioural change for earlier C modes or C++ translation units. The kernel is likewise unaffected, as it does not include userland headers. As function-like macros, they are transparent except at a call site where the address-of operator is applied, the macro is suppressed via `#undef`, or the identifier appears in parenthesised form; all of which cause the underlying function designator to be used instead.

* fts: reduce fd usage by storing fts_dirfd on directory entries onlyJitendra Bhati2026-08-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | Previously fts_build() called _dup(_dirfd(dirp)) for every child entry, holding N simultaneous fds for a directory with N children. Redefine fts_dirfd: instead of a fd for the entry's parent directory, it is now a fd for the entry itself, set only for directory entries. One dup per directory in fts_build() instead of one per child. Close fts_dirfd during the directory post-order visit, before advancing to its sibling. To access a file using fd-relative operations, callers should use openat(ent->fts_parent->fts_dirfd, ent->fts_name, ...) instead of openat(ent->fts_dirfd, ent->fts_name, ...). The fd is valid until the directory's post-order visit (FTS_DP).

| | | | | | | | | | | | | | | | | | | | | Add C23 sized deallocation entry points as thin wrappers around free(3). Implementations may ignore size and alignment hints, so behaviour stays correct for existing allocations without validating caller metadata yet. When jemalloc is updated to 5.3.1, rewire these to je_free_sized() and je_free_aligned_sized() so deallocation can use the allocator's sized deallocation (free_sized for fast paths and free_aligned_sized for correct aligned hints.) Please note this change satisfies the standard interface only. Both functions should be delegated to jemalloc after the upgrade so callers get the intended allocator behaviour; until then, hints are unused and neither sized nor aligned-sized deallocation optimizations apply.

| | | | | | | | | | | | | | | | | | | | | | | | style(9) still allows TAB after #define but this is a historical artifact and by far the minority of uses cases. Going forward, we would like to promote the use of a single space, as it allows alignment to survive line prefixing (such as in diffs). style(9) also has prescribed a single space between '#else' or '#endif' and a comment recalling the guard since 2002. So, commit 157c184689ea ("assert.h: Remove leading tabs for whitespace consistency") was good, and in line with rules about whitespace changes (since the file was heavily modified by surrounding commits).

* zzz: Rewrite to use new power deviceAymeric Wibo2026-05-261-0/+1
| | | | | | | | | | | | | | | | | | | | | Previous script called acpiconf(8) (or apm(8) if ACPI wasn't supported, although this was anyway redundant because APMIO just uses ACPI now). Since a new generic power management interface was introduced, this isn't sufficient, as this would only work for ACPI systems and for ACPI S3 suspend (so no way to select suspend-to-idle). Rewrite in C to take advantage of the new power interface. We may want to add a switch to manually override the kern.power.suspend sysctl, which is otherwise what the power device uses to decide which suspend type to switch to (suspend-to-idle or firmware suspend), but this will require us to amend the power interface.

* tests: fix remaining test failures under _FORTIFY_SOURCEKyle Evans2026-05-011-0/+7
| | | | | | | | | | | The getgroups test is a NetBSD tests, so just apply our larger hammer and disable the feature entirely. The audit test can take a more surgical approach and use __ssp_real() appropriately, since it's a local one. PR: 294881 Reviewed by: markj Differential Revision: https://reviews.freebsd.org/D56735
* ssp: fix our gets_s implementation under _FORTIFY_SOURCEKyle Evans2026-05-011-1/+29
| | | | | | | | | | | | | | | Annex K specifies an interface for handling constraint violations from gets_s, but we previously broke this for some classes of get_s misuse. Provide a more nuanced version that tries to dodge errors that would trigger a constraint handler while still providing value. Notably, we don't want to trigger a failure unless the passed-in length reasonably fits within an RSIZE_MAX, because gets_s will immediately call larger lengths bogus and fail.

* include/stdbit.h: declare size_t, (u)int*_t, and (u)int_least*_tRobert Clausecker2026-04-201-1/+21
| | | | | | | | | | | | | | | | These are required by ISO/IEC 9899:2024 § 7.18.1 ¶ 1 but were forgotten in my initial work. The current approach leaks intptr_t, uintptr_t, intmax_t, and uintmax_t through <sys/_stdint.h>. This could be avoided using a more complicated approach if desired.
