+Subject: [PATCH 1/4] attr: Fix reading of server_reply
+
+read_server_reply first reads boothc header and then rest of packet
+which contains hmac info. This should go in memory right after
+boothc_header and not after full length of packet, because full length
+of packet already contains hmac info.
+
+Solution is to simply use length of header and not length of packet.
+
+Longer term and better solution would be to drop read_server_reply
+completely and use recv_auth which is used for everything else but attr
+set and delete.

+Subject: [PATCH 2/4] auth: Check result of gcrypt gcry_md_get_algo_dlen
+
+When unknown hash is passed to gcry_md_get_algo_dlen 0 is returned. This
+value is then used for memcmp so wrong hmac might be accepted as
+correct.
