The hpt27xx ioctl handler allocates a buffer without M_ZERO and calls hpt_do_ioctl(), which might not overwrite the entire buffer. Also zero bytesReturned in case it is not written by hpt_do_ioctl(). The hpt27xx device has permissions only for root so this is not urgent, and the fix can be MFCd and considered for a future EN.

Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. 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.

The hpt27xx(4), hptnr(4), and hptrr(4) drivers declare MIN() and MAX() internally which match the macros from sys/param.h. MIN() is not used, MAX is only used once and can be replaced with the max() version in libkern.h which operates on u_ints. MFC after: 2 weeks
The sim_vid, hba_vid, and dev_name fields of struct ccb_pathinq are fixed-length strings. AFAICT the only place they're read is in sbin/camcontrol/camcontrol.c, which assumes they'll be null-terminated. However, the kernel doesn't null-terminate them. A bunch of copy-pasted code uses strncpy to write them, and doesn't guarantee null-termination. For at least 4 drivers (mpr, mps, ciss, and hyperv), the hba_vid field actually overflows. You can see the result by doing "camcontrol negotiate da0 -v". This change null-terminates those fields everywhere they're set in the kernel. It also shortens a few strings to ensure they'll fit within the 16-character field.

Most of these are BARs, and we allocate them in their entirety. The one outlier in this is amdsbwd, which calls bus_set_resource() prior. Reviewed by: jhb Differential Revision: https://reviews.freebsd.org/D5370 (partial)
Since these calls only use default arguments, bus_alloc_resource_any() is the right call. Differential Revision: https://reviews.freebsd.org/D5306
