libceph: add nocephx_sign_messages option
Support for message signing was merged into 3.19, along with nocephx_require_signatures option. But, all that option does is allow the kernel client to talk to clusters that don't support MSG_AUTH feature bit. That's pretty useless, given that it's been supported since bobtail. Meanwhile, if one disables message signing on the server side with "cephx sign messages = false", it becomes impossible to use the kernel client since it expects messages to be signed if MSG_AUTH was negotiated. Add nocephx_sign_messages option to support this use case. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
