In this mode, ktrdump polls the kernel's trace buffer periodically (currently hardcoded as a 50 millisecond interval) and dumps any newly added entries. Fancier logic for the timeout (e.g. a command line option or some kind of backoff based on the time since the last entry) can be added later as the need arises. While here, fix some bugs from when this was Capsicum-ized: - Use caph_limit_stream() for the output stream so that isatty() works and the output can be line-buffered (especially useful for live mode). - Use caph_limit_stderr() to permit error messages to be displayed if an error occurs after cap_enter().

The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended. 2017-10-31T00:07:04Z Bryan Drewery bdrewery@FreeBSD.org 2017-10-31T00:07:04Z urn:sha1:ea825d02749f382c3f7e17f28247f20a48733eab Sponsored by: Dell EMC Isilon 2017-09-11T15:18:43Z Mark Johnston markj@FreeBSD.org 2017-09-11T15:18:43Z urn:sha1:8e15d40d24ea4d32c7078c10829032f5411d2a8c libkvm does not set an error string in this case, so we were previously failing silently.

It would be nice to restrict the KVM files, but that's up to libkvm. We wait until after kvm_nlist() is invoked to cap_enter() because kldsym() isn't supported in the Capsicum sandbox.

Churn would be reduced if this was able to be limited to direct dependencies. Sponsored by: EMC / Isilon Storage Division
