Mark Johnston 1a2a481caf pf: Force logging if pf_create_state() fails
Currently packets are logged before pf_create_state() is called, so we
might log a packet as passed that is subsequently dropped due to state
creation failure.  In particular, the drop is not logged, which is
wrong.

Improve the situation a bit: force logging if state creation fails.
This isn't totally right as we'll end up logging the packet twice in
this case, but it's better than not logging the drop at all.

Add a regression test.

FreeBSD Kernel Source:

This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.

Kernel configuration files are located in the conf/ subdirectory of each architecture. GENERIC is the configuration used in release builds. NOTES contains documentation of all possible entries. LINT is a compile-only configuration used to maximize build coverage and detect regressions.

Documentation:

Source code documentation is maintained in a set of man pages, under section 9. These pages are located in share/man/man9, from the top-level of the src tree. Consult intro(9) for an overview of existing pages.

Some additional high-level documentation of the kernel is maintained in the Architecture Handbook.
