Wed, 13 Apr 2022 16:47:08 +0200

libsysdecode: Fix decoding of Capsicum rightsCapsicum rights are a bit tricky since some of them are subsets ofothers, and one can have rights R1 and R2 such that R1 is a subset ofR2, but there is no collection of named rights whose union is R2. So,they don't behave like most other flag sets. sysdecode_cap_rights(3)does not handle this properly and so can emit misleading decodings.Try to fix all of these problems:- Include composite rights in the caprights table.- Use a constructor to sort the caprights table such that "larger" rights appear first and thus are matched first.- Don't print rights that are a subset of rights already printed, so as to minimize the length of the output.- Print a trailing message if some of the specific rights are not matched by the table.PR: 263165Reviewed by: pauamma_gundo.com (doc), jhb, emasteMFC after: 2 weeksSponsored by: The FreeBSD FoundationDifferential Revision: https://reviews.freebsd.org/D34874 List of files: /freebsd/lib/libsysdecode/mktables
