These are more pretty-printers for generic ASN.1 structures. They're never called externally and otherwise are only used in the X509V3_EXT_PARSE_UNKNOWN mode for the X509 pretty-print functions. That makes unknown extensions pretty-print as ASN.1 structures. This is a rather useless feature, so have that fall through to X509V3_EXT_DUMP_UNKNOWN which does a hexdump instead. (The immediate trigger is I don't know what |op| is in upstream's 8c918b7b9c93ba38790ffd1a83e23c3684e66f57 and don't think it is worth the time to puzzle that out and verify it. Better ditch this code completely.) Change-Id: I0217906367d83056030aea64ef344d4fedf74763 Reviewed-on: https://boringssl-review.googlesource.com/8243 Reviewed-by: David Benjamin <davidben@google.com>
