2010-05-17ceph: wait for mds OPEN reply to indicate reconnect successSage Weil
We used to infer reconnect success by watching the MDS state, essentially assuming that hearing nothing meant things were ok. That wasn't particularly reliable. Instead, the MDS replies with an explicit OPEN message to indicate success. Strictly speaking, this is a protocol change, but it is a backwards compatible one that does not break new clients + old servers or old clients + new servers. At least not yet. Drop unused @all argument from kick_requests while we're at it. Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17ceph: only send cap releases when mds is OPEN|HUNGSage Weil
On OPENING we shouldn't have any caps (or releases). On CLOSING, we should wait until we succeed (and throw it all out), or don't (and are OPEN again). On RECONNECTING we can wait until we are OPEN. Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17ceph: dicard cap releases on mds restartSage Weil
If the MDS restarts, the expire caps state is no longer shared, and can be thrown out. Caps state will be rebuilt on the MDS during the reconnect process that follows. Zero out any release messages and adjust the release counter accordingly. Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17ceph: make mon client statfs handling more genericYehuda Sadeh
This is being done so that we could reuse the statfs infrastructure with other requests that return values. Signed-off-by: Yehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17ceph: drop src address(es) from message header [new protocol feature]Sage Weil
The CEPH_FEATURE_NOSRCADDR protocol feature avoids putting the full source address in each message header (twice). This patch switches the client to the new scheme, and _requires_ this feature on the server. The server will support both the old and new schemes. That means an old client will work with a new server, but a new client will not work with an old server. Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17ceph: cleanup: remove unused assignementDan Carpenter
We don't ever use "dirty" so we can remove it. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Sage Weil <sage@newdream.net>

Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17ceph: name bdi ceph-%d instead of major:minorSage Weil
The bdi_setup_and_register() helper doesn't help us since we bdi_init() in create_client() and bdi_register() only when sget() succeeds. Signed-off-by: Sage Weil <sage@newdream.net>

Ensure all options are included in /proc/mounts. Some cleanup. Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17ceph: set dn offset when splicedSage Weil
We want to assign an offset when the dentry goes from null to linked, which is always done by splice_dentry(). Notably, we should NOT assign an offset when a dentry is first created and is still null. BUG if we try to splice a non-null dentry (we shouldn't). Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17ceph: don't clobber i_max_offset on already complete dirSage Weil
This can screw up offsets assigned to new dentries and break dcache readdir results. Signed-off-by: Sage Weil <sage@newdream.net>

Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17ceph: set next_offset on readdir finishSage Weil
Set next_offset to 2 (always 2!), not 0, on readdir finish. Signed-off-by: Sage Weil <sage@newdream.net>

2010-05-17ceph: fix xattr dangling pointer / double freeSage Weil
If we use the xattr_blob, clear the pointer so we don't release the memory at the bottom of the fuction. Reported-by: Henry C Chang <henry_c_chang@tcloudcomputing.com> Signed-off-by: Sage Weil <sage@newdream.net>

2010-05-17ceph: d_obtain_alias() returns ERR_PTR()Dan Carpenter

2010-05-17ceph: wake up mount thread when getting osdmapYehuda Sadeh

2010-05-17ceph: simplify ceph_msg_newSage Weil
We only need to pass in front_len. Callers can attach any other payload pieces (middle, data) as they see fit. Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17ceph: make ceph_msg_new return NULL on failure; clean up, fix callersSage Weil
Returning ERR_PTR(-ENOMEM) is useless extra work. Return NULL on failure instead, and fix up the callers (about half of which were wrong anyway). Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17ceph: rewrite msgpool using mempool_tSage Weil
Since we don't need to maintain large pools of messages, we can just use the standard mempool_t. We maintain a msgpool 'wrapper' because we need the mempool_t* in the alloc function, and mempool gives us only pool_data. Signed-off-by: Sage Weil <sage@newdream.net>
2010-05-17ceph: use ceph_sb_to_client instead of ceph_clientCheng Renquan
ceph_sb_to_client and ceph_client are really identical, we need to dump one; while function ceph_client is confusing with "struct ceph_client", ceph_sb_to_client's definition is more clear; so we'd better switch all call to ceph_sb_to_client. -static inline struct ceph_client *ceph_client(struct super_block *sb) -{ - return sb->s_fs_info; -} Signed-off-by: Cheng Renquan <crquan@gmail.com> Signed-off-by: Sage Weil <sage@newdream.net>

2010-05-17ceph: fix theoretically possible double-put on connectionSage Weil
This would only trigger if we bailed out before resetting r_con_filling_msg because the server reply was corrupt (oversized). Signed-off-by: Sage Weil <sage@newdream.net>

2010-05-17ceph: use __page_cache_alloc and add_to_page_cache_lruYehuda Sadeh
Following Nick Piggin patches in btrfs, pagecache pages should be allocated with __page_cache_alloc, so they obey pagecache memory policies. Also, using add_to_page_cache_lru instead of using a private pagevec where applicable. Signed-off-by: Yehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>

2010-05-17cifs: fix noserverino handling when unix extensions are enabledJeff Layton
The uniqueid field sent by the server when unix extensions are enabled is currently used sometimes when it shouldn't be. The readdir codepath is correct, but most others are not. Fix it. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>
2010-05-17cifs: don't update uniqueid in cifs_fattr_to_inodeJeff Layton
We use this value to find an inode within the hash bucket, so we can't change this without re-hashing the inode. For now, treat this value as immutable. Eventually, we should probably use an inode number change on a path based operation to indicate that the lookup cache is invalid, but that's a bit more code to deal with.

2010-05-17cifs: always revalidate hardlinked inodes when using noserverinoJeff Layton
The old cifs_revalidate logic always revalidated hardlinked inodes. This hack allowed CIFS to pass some connectathon tests when server inode numbers aren't used (basic test7, in particular). Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>
