Bug ID: 2306
Summary: ssh-add 6.7 inserts RSA keys into the ssh-agent as
"rsa w/o comment" instead of filenames
Product: Portable OpenSSH
Version: 6.7p1
Hardware: Other
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: ssh-add
Assignee: unassigned-bugs at mindrot.org
Reporter: dkg at fifthhorseman.net
as of version 6.7 (the first version i noticed this in), it looks to me
like adding ssh keys to ssh-agent marks them all as "rsa w/o comment",
instead of putting the filename as the comment.
This appears to be because of the key function overhaul in
8668706d0f52654fe64c0ca41a96113aeab8d2b8.
ssh-add.c loads the secret keys via library-like invocations of
functions in sshkey.c, and if the comment returned is NULL, it sets the
comment to be the filename.
But in practice, these functions now return "rsa w/o comment" as the
comment, so the filename never gets applied as a comment.
Possible ways to fix:
* One fix would be to have the functions return a NULL for the
comment.
* Another fix would be to have ssh-add just override the comment
explicitly.
* A third fix would be to pass a "proposed comment" into the
library-like call, which could be overridden by future versions if
they're aware of a superior comment after having parsed the key.
I also note that there is no way for a user of ssh-add to explicitly
set
the comment directly -- adding something like that would be a distinct
feature, i think.
