New Revision: 304075
URL: https://svnweb.freebsd.org/changeset/base/304075

Log:
  MFV r304060:
  Sync libarchive with vendor including three security fixes
  
  Vendor issues fixed:
  
  Issue #744: Very long pathnames evade symlink checks
  Issue #748: libarchive can compress, but cannot decompress zip some files
  PR #750: ustar: fix out of bounds read on empty string ("") filename
  PR #755: fix use of acl_get_flagset_np() on FreeBSD
  
  MFC after:	3 days
