+Subject: [PATCH] util: Simplify input validation
+
+It appears that snprintf(3) is being used for input validation.
+However, this seems like overkill because it causes szPath to be
+copied an extra time. The mostly likely protections being sought
+here, according to https://cwe.mitre.org/data/definitions/20.html,
+look to be DoS attacks involving CPU and memory usage. A simpler
+check that uses strnlen(3) can mitigate against both of these and is
+simpler.

+Subject: [PATCH] util: Fix build on FreeBSD by avoiding NSS_BUFLEN_PASSWD
+
+NSS_BUFLEN_PASSWD is not defined on FreeBSD. Use
+sysconf(_SC_GETPW_R_SIZE_MAX) instead, as per POSIX.
+
+Use a dynamically allocated buffer instead of trying to cram all of
+the logic into the declarations. This will come in useful later
+anyway.
