From 87515e39295e4b7eaec1641c38e1ac32e8d39a91 Mon Sep 17 00:00:00 2001 From: "Neal H. Walfield" Date: Thu, 25 Feb 2016 21:22:55 +0100 Subject: [PATCH] gpg: Show debugging info if a sig with an unsupported sig class is used. * g10/sig-check.c (check_key_signature2): If SIG->CLASS is unsupported, show some debugging information. Don't use BUG to fail. Just return GPG_ERR_BAD_SIGNATURE. -- Signed-off-by: Neal H.
