The core code gets a few cleanups and Chaitanya has added support for TCP_NODELAY (which has been used on the server side for ages but we somehow missed on the kernel client). There is also an update to MAINTAINERS to fix up some email addresses and reflect that Ilya and Zheng are doing most of the maintenance for RBD and CephFS these days.

2015-02-19libceph: fix double __remove_osd() problemIlya Dryomov
It turns out it's possible to get __remove_osd() called twice on the same OSD. That doesn't sit well with rb_erase() - depending on the shape of the tree we can get a NULL dereference, a soft lockup or a random crash at some point in the future as we end up touching freed memory. One scenario that I was able to reproduce is as follows: <osd3 is idle, on the osd lru list> <con reset - osd3> con_fault_finish() osd_reset() <osdmap - osd3 down> ceph_osdc_handle_map() <takes map_sem> kick_requests() <takes request_mutex> reset_changed_osds() __reset_osd() __remove_osd() <releases request_mutex> <releases map_sem> <takes map_sem> <takes request_mutex> __kick_osd_requests() __reset_osd() __remove_osd() <-- !!! A case can be made that osd refcounting is imperfect and reworking it would be a proper resolution, but for now Sage and I decided to fix this by adding a safe guard around __remove_osd().

This converts the rbd driver to use the blk-mq infrastructure. Except for switching to a per-request work item this is almost mechanical.

2015-02-19ceph: return error for traceless reply raceYan, Zheng
When we receives traceless reply for request that created new inode, we re-send a lookup request to MDS get information of the newly created inode. (VFS expects FS' callback return an inode in create case) This breaks one request into two requests. Other client may modify or move to the new inode in the middle. When the race happens, ceph_handle_notrace_create() unconditionally links the dentry for 'create' operation to the inode returned by lookup. This may confuse VFS when the inode is a directory (VFS does not allow multiple linkages for directory inode). This patch makes ceph_handle_notrace_create() when it detect a race. This event should be rare and it happens only when we talk to old MDS. Recent MDS does not send traceless reply for request that creates new inode. Signed-off-by: Yan, Zheng <zyan@redhat.com>

2015-02-19rbd: do not treat standalone as flattenIlya Dryomov
If the clone is resized down to 0, it becomes standalone. If such resize is carried over while an image is mapped we would detect this and call rbd_dev_parent_put() which means "let go of all parent state, including the spec(s) of parent images(s)". This leads to a mismatch between "rbd info" and sysfs parent fields, so a fix is in order. # rbd create --image-format 2 --size 1 foo # rbd snap create foo@snap # rbd snap protect foo@snap # rbd clone foo@snap bar # DEV=$(rbd map bar) # rbd resize --allow-shrink --size 0 bar # rbd resize --size 1 bar # rbd info bar | grep parent parent: rbd/foo@snap Before: # cat /sys/bus/rbd/devices/0/parent (no parent image) After: # cat /sys/bus/rbd/devices/0/parent pool_id 0 pool_name rbd image_id 10056b8b4567 image_name foo snap_id 2 snap_name snap overlap 0 Signed-off-by: Ilya Dryomov <idryomov@redhat.com> Reviewed-by: Josh Durgin <jdurgin@redhat.com> Reviewed-by: Alex Elder <elder@linaro.org>

2015-02-19ceph: properly zero data pages for file holes.Yan, Zheng
A bug is found in striped_read() of fs/ceph/file.c. striped_read() calls ceph_zero_pape_vector_range(). The first argument, page_align + read + ret, passed to ceph_zero_pape_vector_range() is wrong. When a file has holes, this wrong parameter may cause memory corruption either in kernal space or user space. Kernel space memory may be corrupted in the case of non direct IO; user space memory may be corrupted in the case of direct IO. In the latter case, the application doing direct IO may crash due to memory corruption, as we have experienced. The correct value should be initial_align + read + ret, where intial_align = o_direct ? buf_align : io_align. Compared with page_align, the current page offest, initial_align is the initial page offest, which should be used to calculate the page and offset in ceph_zero_pape_vector_range().

Pull networking updates from David Miller: 1) Missing netlink attribute validation in nft_lookup, from Patrick McHardy. 2) Restrict ipv6 partial checksum handling to UDP, since that's the only case it works for. From Vlad Yasevich. 3) Clear out silly device table sentinal macros used by SSB and BCMA drivers. From Joe Perches. 4) Make sure the remote checksum code never creates a situation where the remote checksum is applied yet the tunneling metadata describing the remote checksum transformation is still present. Otherwise an external entity might see this and apply the checksum again. From Tom Herbert. 5) Use msecs_to_jiffies() where applicable, from Nicholas Mc Guire. 6) Don't explicitly initialize timer struct fields, use setup_timer() and mod_timer() instead. From Vaishali Thakkar. 7) Don't invoke tg3_halt() without the tp->lock held, from Jun'ichi Nomura. 8) Missing __percpu annotation in ipvlan driver, from Eric Dumazet. 9) Don't potentially perform skb_get() on shared skbs, also from Eric Dumazet. 10) Fix COW'ing of metrics for non-DST_HOST routes in ipv6, from Martin KaFai Lau. 11) Fix merge resolution error between the iov_iter changes in vhost and some bug fixes that occurred at the same time. From Jason Wang. 12) If rtnl_configure_link() fails we have to perform a call to ->dellink() before unregistering the device.
