Subject: [PATCH] mount.ceph: remove arbitrary limit on size of name= option
|
||||
|
||||
Aaron was getting back -ERANGE errors when trying to mount using
|
||||
a long name= option. The issue is that the destination buffer for the
|
||||
"key=" string is not big enough to hold long names.
|
||||
|
||||
When I overhauled the mount.ceph code recently, I made this buffer much
|
||||
smaller than before figuring that it didn't need to be any larger than
|
||||
the length of "secret=<base64 encoded key>".
|
||||
|
||||
In the case where the secret is set in the keyring though, this buffer
|
||||
needs to be able to hold a string like "key=client.<cephx name>". The
|
||||
cephx name can be of arbitrary length, however.
|
||||
|
||||
Rework the code to just safe_cat the strings directly into the options
|
||||
buffer, eliminating an extra copy and the need for an arbitrary limit.
|
||||
This also allows us to remove get_secret_option() from the the common
|
||||
code as well.
