Remove $FreeBSD$: one-line nroff pattern

Remove /^\.\\"\s*\$FreeBSD\$$\n/

Add AT_EMPTY_PATH for several *at(2) syscalls

2021-04-15T09:48:11+00:00

It is currently allowed to fchownat(2), fchmodat(2), fchflagsat(2),
utimensat(2), fstatat(2), and linkat(2).

For linkat(2), PRIV_VFS_FHOPEN privilege is required to exercise the flag.
It allows to link any open file.

open(2): Remove O_BENEATH and AT_BENEATH

2021-03-02T18:16:55+00:00

with the reasoning that the flags did not worked properly, and were not
shipped in a release.

O_RESOLVE_BENEATH is kept as useful.

Document EINTEGRITY errors for many system calls.

2020-03-30T21:44:00+00:00

EINTEGRITY was previously documented as a UFS-specific error for
mount(2).  This documents EINTEGRITY as a filesystem-independent error
that may be reported by the backing store of a filesystem.

While here, document EIO as a filesystem-independent error for both
mount(2) and posix_fadvise(2).  EIO was previously only documented for
UFS for mount(2).

First draft of documentation for AT/O_BENEATH handling of the absolute

paths.

It was decided that committing the code and drafting of the man page
update is better than allowing the code to rot until wordsmithing
happens.

Implement O_BENEATH and AT_BENEATH.

2018-10-25T22:16:34+00:00

Flags prevent open(2) and *at(2) vfs syscalls name lookup from
escaping the starting directory.  Supposedly the interface is similar
to the same proposed Linux flags.

but after v1 weren't changed.

Renumber copyright clause 4

2017-02-28T23:42:47+00:00

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

S_ISTXT is non-standard.

While here, also update fchmodat() standards entry to POSIX.1-2008.
