libceph: set global_id as soon as we get an auth ticket

2021-06-24T19:03:17+00:00

Commit 61ca49a9105f ("libceph: don't set global_id until we get an auth ticket") delayed the setting of global_id too much. It is set only after all tickets are received, but in pre-nautilus clusters an auth ticket and the service tickets are obtained in separate steps (for a total of three MAuth replies). When the service tickets are requested, global_id is used to build an authorizer; if global_id is still 0 we never get them and fail to establish the session. Moving the setting of global_id into protocol implementations. This way global_id can be set exactly when an auth ticket is received, not sooner nor later.

libceph: don't pass result into ac->ops->handle_reply()

2021-06-24T19:03:16+00:00

There is no result to pass in msgr2 case because authentication failures are reported through auth_bad_method frame and in MAuth case an error is returned immediately. Signed-off-by: Ilya Dryomov Reviewed-by: Jeff Layton

libceph: deprecate [no]cephx_require_signatures options

2021-02-16T11:09:52+00:00

These options were introduced in 3.19 with support for message signing and are rather useless, as explained in commit a51983e4dd2d ("libceph: add nocephx_sign_messages option"). Deprecate them. In case there is someone out there with a cluster that lacks support for MSG_AUTH feature (very unlikely but has to be considered since we haven't formally raised the bar from argonaut to bobtail yet), make nocephx_sign_messages also waive MSG_AUTH requirement. This is probably how it should have been done in the first place -- if we aren't going to sign, requiring the signing feature makes no sense. Signed-off-by: Ilya Dryomov Reviewed-by: Jeff Layton

libceph, ceph: implement msgr2.1 protocol (crc and secure modes)

2020-12-14T22:21:50+00:00

Implement msgr2.1 wire protocol, available since nautilus 14.2.11 and octopus 15.2.5. msgr2.0 wire protocol is not implemented -- it has several security, integrity and robustness issues and therefore considered deprecated. Signed-off-by: Ilya Dryomov

libceph: introduce connection modes and ms_mode option

2020-12-14T22:21:50+00:00

msgr2 supports two connection modes: crc (plain) and secure (on-wire encryption). Connection mode is picked by server based on input from client. Introduce ms_mode option: ms_mode=legacy - msgr1 (default) ms_mode=crc - crc mode, if denied fail ms_mode=secure - secure mode, if denied fail ms_mode=prefer-crc - crc mode, if denied agree to secure mode ms_mode=prefer-secure - secure mode, if denied agree to crc mode ms_mode affects all connections, we don't separate connections to mons like it's done in userspace with ms_client_mode vs ms_mon_client_mode. For now the default is legacy, to be flipped to prefer-crc after some time. Signed-off-by: Ilya Dryomov

libceph, rbd: ignore addr->type while comparing in some cases

2020-12-14T22:21:50+00:00

For libceph, this ensures that libceph instance sharing (share option) continues to work. For rbd, this avoids blocklisting alive lock owners (locker addr is always LEGACY, while watcher addr is ANY in nautilus). Signed-off-by: Ilya Dryomov

libceph, ceph: get and handle cluster maps with addrvecs

2020-12-14T22:21:50+00:00

In preparation for msgr2, make the cluster send us maps with addrvecs including both LEGACY and MSGR2 addrs instead of a single LEGACY addr. This means advertising support for SERVER_NAUTILUS and also some older features: SERVER_MIMIC, MONENC and MONNAMES. MONNAMES and MONENC are actually pre-argonaut, we just never updated ceph_monmap_decode() for them. Decoding is unconditional, see commit 23c625ce3065 ("libceph: assume argonaut on the server side"). SERVER_MIMIC doesn't bear any meaning for the kernel client. Since ceph_decode_entity_addrvec() is guarded by encoding version checks (and in msgr2 case it is guarded implicitly by the fact that server is speaking msgr2), we assume MSG_ADDR2 for it.
