git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull time namespace updates from Christian Brauner: "When time namespaces were introduced we missed to virtualize the 'btime' field in /proc/stat. This confuses tasks which are in another time namespace with a virtualized boottime which is common in some container workloads. This contains Michael's series to fix 'btime' which Thomas asked me to take through my tree. To fix 'btime' virtualization we simply subtract the offset of the time namespace's boottime from btime before printing the stats. Note that since start_boottime of processes are seconds since boottime and the boottime stamp is now shifted according to the time namespace's offset, the offset of the time namespace also needs to be applied before the process stats are given to userspace. This avoids that processes shown by tools such as 'ps' appear as time travelers in the corresponding time namespace. Selftests are included to verify that btime virtualization in /proc/stat works as expected" * tag 'time-namespace-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: namespace: make timens_on_fork() return nothing selftests/timens: added selftest for /proc/stat btime fs/proc: apply the time namespace offset to /proc/stat btime timens: additional helper functions for boottime offset handling

2020-12-14libceph, ceph: get and handle cluster maps with addrvecsIlya Dryomov2-11/+12
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.

In preparation for msgr2, update handle_reply() and verify_authorizer_reply() auth ops to propagate session key and connection secret. Since nautilus, if secure mode is negotiated, connection secret is shared either in CEPHX_GET_AUTH_SESSION_KEY reply (for mons) or in a final authorizer reply (for osds and mdses).

2020-12-14ceph: implement updated ceph_mds_request_head structureJeff Layton1-13/+62
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.

2020-12-14ceph: 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.

2020-12-14Revert "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.

2020-12-14ceph: 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.

2020-12-14ceph: 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.
