            Bug ID: 2313
           Summary: Corrupt KRL file when using multiple CA.
           Product: Portable OpenSSH
           Version: 6.5p1
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: major
          Priority: P5
         Component: ssh-keygen
          Assignee: unassigned-bugs at mindrot.org
          Reporter: peter at pean.org

When I have a KRL containing revokations from multiple CA it gets
corrupted some way. sshd cant read it.

This is what sshd says:
debug1: KRL version 0 generated at 20141114T080704
debug3: ssh_krl_from_blob: first pass, section 0x01
debug3: ssh_krl_from_blob: first pass, section 0x01
debug3: ssh_krl_from_blob: second pass, section 0x01
debug3: parse_revoked_certs: subsection type 0x20
debug3: revoked_certs_for_ca_key: new CA RSA
debug3: parse_revoked_certs: subsection type 0x22
debug3: parse_revoked_certs: subsection type 0x20
debug3: ssh_krl_from_blob: second pass, section 0x01
debug3: parse_revoked_certs: subsection type 0x20
debug3: parse_revoked_certs: subsection type 0x22
debug3: parse_revoked_certs: subsection type 0x20
buffer_get_string_ptr: bad string length 268032
parse_revoked_certs: buffer error
Invalid KRL, refusing public key authentication


I generated the KRL using two textfiles containing 
multiple serial: <serial> lines like this:
ssh-keygen -k -u -f revoked_keys.bin -s ca1.pub revoked_keys1
ssh-keygen -k -u -f revoked_keys.bin -s ca2.pub revoked_keys2

I have tried to remove the revoked_keys.bin and generate a new one
without success. I even tried revoking from ca2 first and then ca1..
