2016-03-25ceph: use lookup request to revalidate dentryYan, Zheng2-0/+35
If dentry has no lease, ceph_d_revalidate() previously return 0. This causes VFS to invalidate the dentry and create a new dentry for later lookup. Invalidating a dentry also detach any underneath mount points. So mount point inside cephfs can disapear mystically (even the mount point is not modified by other hosts). The fix is using lookup request to revalidate dentry without lease. This can partly solve the mount points disapear issue (as long as the mount point is not modified by other hosts) Signed-off-by: Yan, Zheng <[email protected]>

2016-03-25ceph: fix security xattr deadlockYan, Zheng8-11/+125
When security is enabled, security module can call filesystem's getxattr/setxattr callbacks during d_instantiate(). For cephfs, d_instantiate() is usually called by MDS' dispatch thread, while handling MDS reply. If the MDS reply does not include xattrs and corresponding caps, getxattr/setxattr need to send a new request to MDS and waits for the reply. This makes MDS' dispatch sleep, nobody handles later MDS replies. The fix is make sure lookup/atomic_open reply include xattrs and corresponding caps. So getxattr can be handled by cached xattrs. This requires some modification to both MDS and request message. (Client tells MDS what caps it wants; MDS encodes proper caps in the reply) Smack security module may call setxattr during d_instantiate(). Unlike getxattr, we can't force MDS to issue CEPH_CAP_XATTR_EXCL to us. So just make setxattr return error when called by MDS' dispatch thread. Signed-off-by: Yan, Zheng <[email protected]>

2016-03-25ceph: fix race during filling readdir cacheYan, Zheng1-2/+7

2016-03-25libceph: use sizeof_footer() moreIlya Dryomov1-16/+3

2016-03-25ceph: kill ceph_empty_snapcIlya Dryomov4-34/+6
ceph_empty_snapc->num_snaps == 0 at all times. Passing such a snapc to ceph_osdc_alloc_request() (possibly through ceph_osdc_new_request()) is equivalent to passing NULL, as ceph_osdc_alloc_request() uses it only for sizing the request message. Further, in all four cases the subsequent ceph_osdc_build_request() is passed NULL for snapc, meaning that 0 is encoded for seq and num_snaps and making ceph_empty_snapc entirely useless. The two cases where it actually mattered were removed in commits 860560904962 ("ceph: avoid sending unnessesary FLUSHSNAP message") and 23078637e054 ("ceph: fix queuing inode to mdsdir's snaprealm").

2016-03-25ceph: scattered page writebackYan, Zheng1-109/+196
This patch makes ceph_writepages_start() try using single OSD request to write all dirty pages within a strip unit. When a nonconsecutive dirty page is found, ceph_writepages_start() tries starting a new write operation to existing OSD request. If it succeeds, it uses the new operation to writeback the dirty page. Signed-off-by: Yan, Zheng <[email protected]>
2016-03-25libceph: add helper that duplicates last extent operationYan, Zheng2-0/+24
This helper duplicates last extent operation in OSD request, then adjusts the new extent operation's offset and length. The helper is for scatterd page writeback, which adds nonconsecutive dirty pages to single OSD request. Signed-off-by: Yan, Zheng <[email protected]> Signed-off-by: Ilya Dryomov <[email protected]>
2016-03-25libceph: enable large, variable-sized OSD requestsIlya Dryomov3-19/+32
Turn r_ops into a flexible array member to enable large, consisting of up to 16 ops, OSD requests. The use case is scattered writeback in cephfs and, as far as the kernel client is concerned, 16 is just a made up number. r_ops had size 3 for copyup+hint+write, but copyup is really a special case - it can only happen once. ceph_osd_request_cache is therefore stuffed with num_ops=2 requests, anything bigger than that is allocated with kmalloc(). req_mempool is backed by ceph_osd_request_cache, which means either num_ops=1 or num_ops=2 for use_mempool=true - all existing users (ceph_writepages_start(), ceph_osdc_writepages()) are fine with that.

2016-03-25libceph: behave in mon_fault() if cur_mon < 0Ilya Dryomov1-14/+9
This can happen if __close_session() in ceph_monc_stop() races with a connection reset. We need to ignore such faults, otherwise it's likely we would take !hunting, call __schedule_delayed() and end up with delayed_work() executing on invalid memory, among other things. The (two!) con->private tests are useless, as nothing ever clears con->private. Nuke them. Signed-off-by: Ilya Dryomov <[email protected]>
2016-03-25libceph: reschedule tick in mon_fault()Ilya Dryomov1-4/+4
Doing __schedule_delayed() in the hunting branch is pointless, as the tick will have already been scheduled by then. What we need to do instead is *reschedule* it in the !hunting branch, after reopen_session() changes hunt_mult, which affects the delay. This helps with spacing out connection attempts and avoiding things like two back-to-back attempts followed by a longer period of waiting around. Signed-off-by: Ilya Dryomov <[email protected]>
2016-03-25libceph: introduce and switch to reopen_session()Ilya Dryomov1-17/+16
hunting is now set in __open_session() and cleared in finish_hunting(), instead of all around. The "session lost" message is printed not only on connection resets, but also on keepalive timeouts. Signed-off-by: Ilya Dryomov <[email protected]>
2016-03-25libceph: monc hunt rate is 3s with backoff up to 30sIlya Dryomov3-9/+22
Unless we are in the process of setting up a client (i.e. connecting to the monitor cluster for the first time), apply a backoff: every time we want to reopen a session, increase our timeout by a multiple (currently 2); when we complete the connection, reduce that multipler by 50%.

2016-03-25libceph: monc ping rate is 10sIlya Dryomov3-9/+5
Split ping interval and ping timeout: ping interval is 10s; keepalive timeout is 30s. Make monc_ping_timeout a constant while at it - it's not actually exported as a mount option (and the rest of tick-related settings won't be either), so it's got no place in ceph_options. Signed-off-by: Ilya Dryomov <[email protected]>
2016-03-25libceph: pick a different monitor when reconnectingIlya Dryomov1-28/+57
Don't try to reconnect to the same monitor when we fail to establish a session within a timeout or it's lost. For that, pick_new_mon() needs to see the old value of cur_mon, so don't clear it in __close_session() - all calls to __close_session() but one are followed by __open_session() anyway. __open_session() is only called when a new session needs to be established, so the "already open?" branch, which is now in the way, is simply dropped. Signed-off-by: Ilya Dryomov <[email protected]>
2016-03-25libceph: revamp subs code, switch to SUBSCRIBE2 protocolIlya Dryomov8-95/+174
It is currently hard-coded in the mon_client that mdsmap and monmap subs are continuous, while osdmap sub is always "onetime". To better handle full clusters/pools in the osd_client, we need to be able to issue continuous osdmap subs. Revamp subs code to allow us to specify for each sub whether it should be continuous or not. Although not strictly required for the above, switch to SUBSCRIBE2 protocol while at it, eliminating the ambiguity between a request for "every map since X" and a request for "just the latest" when we don't have a map yet (i.e. have epoch 0). SUBSCRIBE2 feature bit is now required - it's been supported since pre-argonaut (2010). Move "got mdsmap" call to the end of ceph_mdsc_handle_map() - calling in before we validate the epoch and successfully install the new map can mess up mon_client sub state.

2016-03-25libceph: decouple hunting and subs managementIlya Dryomov1-9/+22

2016-03-25libceph: move debugfs initialization into __ceph_open_session()Ilya Dryomov2-51/+4
Our debugfs dir name is a concatenation of cluster fsid and client unique ID ("global_id"). It used to be the case that we learned global_id first, nowadays we always learn fsid first - the monmap is sent before any auth replies are. ceph_debugfs_client_init() call in ceph_monc_handle_map() is therefore never executed and can be removed. Its counterpart in handle_auth_reply() doesn't really belong there either: having to do monc->client and unlocking early to work around lockdep is a testament to that. Move it into __ceph_open_session(), where it can be called unconditionally. Signed-off-by: Ilya Dryomov <[email protected]>
2016-03-25Revert "ppdev: use new parport device model"Linus Torvalds1-20/+5
This reverts commit e7223f18603374d235d8bb0398532323e5f318b9. It causes problems when a ppdev tries to register before the parport driver has been registered with the device model. That will trigger the BUG_ON(!drv->bus->p); at drivers/base/driver.c:153.
