2020-12-15libceph: rename and export con->state statesIlya Dryomov2-52/+50
In preparation for msgr2, rename msgr1 specific states and move the defines to the header file. Also drop state transition comments. They don't cover all possible transitions (e.g. NEGOTIATING -> STANDBY, etc) and currently do more harm than good. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>

2020-12-15libceph: make sure our addr->port is zero and addr->nonce is non-zeroIlya Dryomov1-10/+17
Our messenger instance addr->port is normally zero -- anything else is nonsensical because as a client we connect to multiple servers and don't listen on any port. However, a user can supply an arbitrary addr:port via ip option and the port is currently preserved. Zero it. Conversely, make sure our addr->nonce is non-zero. A zero nonce is special: in combination with a zero port, it is used to blocklist the entire ip. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>

2020-12-15libceph: remove redundant session reset log messageIlya Dryomov1-4/+3

2020-12-15libceph: split protocol reset bits out of reset_connection()Ilya Dryomov1-26/+24
Move protocol reset bits into ceph_con_reset_protocol(), leaving just session reset bits. Note that con->out_skip is now reset on faults. This fixes a crash in the case of a stateful session getting a fault while in the middle of revoking a message. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
2020-12-15libceph: don't call reset_connection() on version/feature mismatchesIlya Dryomov1-3/+0
A fault due to a version mismatch or a feature set mismatch used to be treated differently from other faults: the connection would get closed without trying to reconnect and there was a ->bad_proto() connection op for notifying about that. This changed a long time ago, see commits 6384bb8b8e88 ("libceph: kill bad_proto ceph connection op") and 0fa6ebc600bc ("libceph: fix protocol feature mismatch failure path"). Nowadays these aren't any different from other faults (i.e. we try to reconnect even though the mismatch won't resolve until the server is replaced). reset_connection() calls there are rather confusing because reset_connection() resets a session together an individual instance of the protocol. This is cleaned up in the next patch. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
2020-12-15libceph: lower exponential backoff delayIlya Dryomov2-5/+11

2020-12-15ceph: implement updated ceph_mds_request_head structureJeff Layton2-14/+93
When we added the btime feature in mainline ceph, we had to extend struct ceph_mds_request_args so that it could be set. Implement the same in the kernel client. Rename ceph_mds_request_head with a _old extension, and a union ceph_mds_request_args_ext to allow for the extended size of the new header format. Add the appropriate code to handle both formats in struct create_request_message and key the behavior on whether the peer supports CEPH_FEATURE_FS_BTIME. The gid_list field in the payload is now populated from the saved credential. For now, we don't add any support for setting the btime via setattr, but this does enable us to add that in the future.

2020-12-15ceph: when filling trace, call ceph_get_inode outside of mutexesJeff Layton2-9/+21
Geng Jichao reported a rather complex deadlock involving several moving parts: 1) readahead is issued against an inode and some of its pages are locked while the read is in flight 2) the same inode is evicted from the cache, and this task gets stuck waiting for the page lock because of the above readahead 3) another task is processing a reply trace, and looks up the inode being evicted while holding the s_mutex. That ends up waiting for the eviction to complete 4) a write reply for an unrelated inode is then processed in the ceph_con_workfn job. It calls ceph_check_caps after putting wrbuffer caps, and that gets stuck waiting on the s_mutex held by 3. The reply to "1" is stuck behind the write reply in "4", so we deadlock at that point. This patch changes the trace processing to call ceph_get_inode outside of the s_mutex and snap_rwsem, which should break the cycle above.

2020-12-15Revert "ceph: allow rename operation under different quota realms"Luis Henriques3-64/+6
This reverts commit dffdcd71458e699e839f0bf47c3d42d64210b939. When doing a rename across quota realms, there's a corner case that isn't handled correctly. Here's a testcase: mkdir files limit truncate files/file -s 10G setfattr limit -n ceph.quota.max_bytes -v 1000000 mv files limit/ The above will succeed because ftruncate(2) won't immediately notify the MDSs with the new file size, and thus the quota realms stats won't be updated. Since the possible fixes for this issue would have a huge performance impact, the solution for now is to simply revert to returning -EXDEV when doing a cross quota realms rename.

2020-12-15ceph: fix race in concurrent __ceph_remove_cap invocationsLuis Henriques1-2/+9
A NULL pointer dereference may occur in __ceph_remove_cap with some of the callbacks used in ceph_iterate_session_caps, namely trim_caps_cb and remove_session_caps_cb. Those callers hold the session->s_mutex, so they are prevented from concurrent execution, but ceph_evict_inode does not. Since the callers of this function hold the i_ceph_lock, the fix is simply a matter of returning immediately if caps->ci is NULL.

2020-12-15ceph: queue MDS requests to REJECTED sessions when CLEANRECOVER is setJeff Layton1-4/+14
Ilya noticed that the first access to a blacklisted mount would often get back -EACCES, but then subsequent calls would be OK. The problem is in __do_request. If the session is marked as REJECTED, a hard error is returned instead of waiting for a new session to come into being. When the session is REJECTED and the mount was done with recover_session=clean, queue the request to the waiting_for_map queue, which will be awoken after tearing down the old session. We can only do this for sync requests though, so check for async ones first and just let the callers redrive a sync request.
