fts: fix fts_accpath regression after fts_children()

2026-08-06T22:51:25Z

When fts_children() is called, sp->fts_child is set. On the next fts_read() call, fts_safe_changedir() was incorrectly passed p->fts_dirfd (pointing to the parent directory) instead of -1. This caused fts to fchdir to the parent instead of the child directory, silently skipping the contents of 3rd-level subdirectories. This was observed as a failure in nmtree_test:mtree_create which calls fts_children() internally. Add regression test accpath_correct_after_descent that calls fts_children() on each directory entry and verifies files at depth 3 are still visited correctly. The test fails with the unfixed libc and passes with the fix. Reported by: Herbert J.

manuals: Fix more Fx and nearby mechanical typos

2026-08-04T14:04:23Z

Fix compiler warnings related to the Fx macro, as well as all other mechanical typos that were visible within one screenful of them. These cause rendering glitches on various toolchains with various of the five and a half decades of rich output formats and tooling manpages scale to. The *x macro set specifies operating systems. These macros take the rest of the line as an argument. Sometimes, a space was not used to separate the argument of Fx and the trailing period. Others had other parts of the sentence supplied as an argument to Fx. While here, fix the other mechanical typos visible on those specific screenfulls. Correct section typo AUTHOR to AUTHORS, markup utilities with Sy, and apply line break after the end of a sentence.

sys/socket.h: Fix AF_MAX

uexterr_gettext(3): support dynamic kernel categories

2026-08-03T21:43:23Z

Add an uncached sysctl based implementation which retrieves individual categories. A cache would be an obvious extension should this optional feature that can only be enabled by an environmental varible have a noticable performance impact in a case that matters.

exterror(9): split category into multiple sources

2026-08-03T21:43:22Z

The static, global index into an array of strings is simple, cheap, and works for the base kernel, but is unworkable for (potentially third-party) kernel modules or for arbitrary userspace code. Swipe a few of the top bits of category to indicate a source with all-zeros being the current model (EXTERR_CAT_SRC_KERN_STATIC). Add two additional sources EXTERR_CAT_SRC_KERN_DYNAMIC and EXTERR_CAT_SRC_USER with stub implementations.

fts: refactor to use fd-relative operations internally

2026-08-03T19:12:28Z

Replace all _open() calls with _openat() in __fts_open(), fts_read(), and fts_children(). Replace statfs() with _fstatfs(). Add fts_dirfd to struct _ftsent, set to the file descriptor of the parent directory. Callers can use openat(ent->fts_dirfd, ent->fts_name, ...) to access files safely without relying on fts_accpath, which enables programs in capability mode to open the files described by _ftsent. This is a preparatory change for fts_openat() which will allow callers to provide a pre-opened directory fd, enabling fts(3) traversal inside Capsicum capability mode. Mirror all fts_open() changes to fts_open_b(). As a result of expanding _ftsend, publish new ELF symbol versions for fts_openat and related functions.
