libceph, ceph: move ceph_osdc_copy_from() into cephfs code

2021-11-08T02:29:52Z

This patch moves ceph_osdc_copy_from() function out of libceph code into cephfs. There are no other users for this function, and there is the need (in another patch) to access internal ceph_osd_request struct members.

ceph: don't rely on error_string to validate blocklisted session.

2021-11-08T02:29:51Z

The "error_string" in the metadata of MClientSession is being parsed by kclient to validate whether the session is blocklisted. The "error_string" is for humans and shouldn't be relied on it. Hence added the flag to MClientsession to indicate the session is blocklisted.

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

2021-06-24T19:03:17Z

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()

2021-06-24T19:03:16Z

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

2021-02-16T11:09:52Z

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)

2020-12-14T22:21:50Z

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

2020-12-14T22:21:50Z

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
