The branch main has been updated by brooks: URL: https://cgit.FreeBSD.org/src/commit/?id=fdccf0336197afe59be6f8859177fe2ff8f87fa6 commit fdccf0336197afe59be6f8859177fe2ff8f87fa6 Author: Brooks Davis <brooks@FreeBSD.org> AuthorDate: 2025-02-19 16:53:32 +0000 Commit: Brooks Davis <brooks@FreeBSD.org> CommitDate: 2025-02-19 16:55:05 +0000 libsys: Don't create or expose __realpathat Previously, __realpathat was in libc and libsys (as is currently standard), but not exported from libc which meant the stub in libc was not filtered and thus libc's copy of the syscall was used. This broke an upcoming change to CheriBSD limiting syscalls to libsys. The realpath(3) implementation now uses __sys___realpathat so there are no consumers of __realpathat. Switch it to PSEUDO (only _foo and __sys_foo symbols) and remove __realpathat from Symbol.map.
