I like your patch, too, especially because it is so much shorter than
mine. But it is also a bit slower, because it still calls pkg_admin 57
times instead of only one time:
$ cd /usr/pkgsrc/pkgtools/pkglint
$ make check-vulnerable PKG_ADMIN=true | grep WARNING | wc -l
Your patch restricts us a bit on the valid PKGBASE names to not use any
regexp metacharacters. We already have packages that contain regexp
$ cd /usr/pkgsrc
$ ls -d */*/ | grep -Eiv '^[-a-z0-9]+/[-_a-z0-9]+/$'
Also we must agree that every pattern in pkg-vulnerabilities contains
the complete PKGBASE as a substring, which is not required by now. So if
you commit your patch, please update the documentation in the
