spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD

2023-05-12T16:44:03+00:00

The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

filemon: Reject FILEMON_SET_FD commands when the fd is a kqueue

2022-02-03T14:41:53+00:00

When FILEMON_SET_FD is used, the filemon handle effectively wraps the
passed file.  In particular, the handle may be inherited by a child
process, or transferred over a unix domain socket, so we must verify
that the backing file permits this.

Add const to input-only char * arguments.

2018-11-02T20:50:22+00:00

These arguments are mostly paths handled by NAMEI*() macros which already
take const char * arguments.

This change improves the match between syscalls.master and the public
declerations of system calls.

Fix some filemon path logging issues.

2018-08-03T19:24:04+00:00

- Properly handle snprintf return value for truncation and avoid
  overflowing the later write with the bogus length.
- Increase the msgbufr size to handle a rename of 2 full files.

The larger allocation causes a slight performance hit which will be mitigated
in the future.  A rewrite with sbufs will likely be done as well.
