2016-05-26libceph: variable-sized ceph_object_idIlya Dryomov1-25/+37
Currently ceph_object_id can hold object names of up to 100 (CEPH_MAX_OID_NAME_LEN) characters. This is enough for all use cases, expect one - long rbd image names: - a format 1 header is named "<imgname>.rbd" - an object that points to a format 2 header is named "rbd_id.<imgname>" We operate on these potentially long-named objects during rbd map, and, for format 1 images, during header refresh. (A format 2 header name is a small system-generated string.) Lift this 100 character limit by making ceph_object_id be able to point to an externally-allocated string. Apart from being able to work with almost arbitrarily-long named objects, this allows us to reduce the size of ceph_object_id from >100 bytes to 64 bytes.

2016-05-26libceph: move message allocation out of ceph_osdc_alloc_request()Ilya Dryomov1-0/+1
The size of ->r_request and ->r_reply messages depends on the size of the object name (ceph_object_id), while the size of ceph_osd_request is fixed. Move message allocation into a separate function that would have to be called after ceph_object_id and ceph_object_locator (which is also going to become variable in size with RADOS namespaces) have been filled in: req = ceph_osdc_alloc_request(...); <fill in req->r_base_oid> <fill in req->r_base_oloc> ceph_osdc_alloc_messages(req); Signed-off-by: Ilya Dryomov <[email protected]>

(4) old OSD session (w/ "none" authorizer) is put ceph_auth_destroy_authorizer(ac, osd->o_auth.authorizer) osd->o_auth.authorizer in the "none" case is just a bare pointer into ac, which contains a single static copy for all services. By the time we get to (4), "none" ac, freed in (2), is long gone. On top of that, a new vtable installed in (3) points us at ceph_x_destroy_authorizer(), so we end up trying to destroy a "none" authorizer with a "cephx" destructor operating on invalid memory! To fix this, decouple authorizer destruction from ac and do away with a single static "none" authorizer by making a copy for each OSD or MDS session. Authorizers themselves are independent of ac and so there is no reason for destroy_authorizer() to be an ac op. Make it an op on the authorizer itself by turning ceph_authorizer into a real struct.

2016-04-04mm, fs: get rid of PAGE_CACHE_* and page_cache_{get,release} macrosKirill A. Shutemov1-2/+2
PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time ago with promise that one day it will be possible to implement page cache with bigger chunks than PAGE_SIZE. This promise never materialized. And unlikely will. We have many places where PAGE_CACHE_SIZE assumed to be equal to PAGE_SIZE. And it's constant source of confusion on whether PAGE_CACHE_* or PAGE_* constant should be used in a particular case, especially on the border between fs and mm. Global switching to PAGE_CACHE_SIZE != PAGE_SIZE would cause to much breakage to be doable. Let's stop pretending that pages in page cache are special. They are not. The changes are pretty straight-forward: - <foo> << (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>; - <foo> >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>; - PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} -> PAGE_{SIZE,SHIFT,MASK,ALIGN}; - page_cache_get() -> get_page(); - page_cache_release() -> put_page(); This patch contains automated changes generated with coccinelle using script below. For some reason, coccinelle doesn't patch header files. I've called spatch for them manually. The only adjustment after coccinelle is revert of changes to PAGE_CAHCE_ALIGN definition: we are going to drop it later. There are few places in the code where coccinelle didn't reach. I'll fix them manually in a separate patch. Comments and documentation also will be addressed with the separate patch. virtual patch @@ expression E; @@ - E << (PAGE_CACHE_SHIFT - PAGE_SHIFT) + E @@ expression E; @@ - E >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) + E @@ @@ - PAGE_CACHE_SHIFT + PAGE_SHIFT @@ @@ - PAGE_CACHE_SIZE + PAGE_SIZE @@ @@ - PAGE_CACHE_MASK + PAGE_MASK @@ expression E; @@ - PAGE_CACHE_ALIGN(E) + PAGE_ALIGN(E) @@ expression E; @@ - page_cache_get(E) + get_page(E) @@ expression E; @@ - page_cache_release(E) + put_page(E) Signed-off-by: Kirill A.

2016-03-25ceph: fix security xattr deadlockYan, Zheng1-1/+2
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]>

2016-03-25libceph: enable large, variable-sized OSD requestsIlya Dryomov1-2/+4
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.

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: revamp subs code, switch to SUBSCRIBE2 protocolIlya Dryomov3-10/+24
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.

2016-01-21libceph: fix ceph_msg_revoke()Ilya Dryomov1-1/+1
There are a number of problems with revoking a "was sending" message: (1) We never make any attempt to revoke data - only kvecs contibute to con->out_skip. However, once the header (envelope) is written to the socket, our peer learns data_len and sets itself to expect at least data_len bytes to follow front or front+middle. If ceph_msg_revoke() is called while the messenger is sending message's data portion, anything we send after that call is counted by the OSD towards the now revoked message's data portion. The effects vary, the most common one is the eventual hang - higher layers get stuck waiting for the reply to the message that was sent out after ceph_msg_revoke() returned and treated by the OSD as a bunch of data bytes. This is what Matt ran into. (2) Flat out zeroing con->out_kvec_bytes worth of bytes to handle kvecs is wrong. If ceph_msg_revoke() is called before the tag is sent out or while the messenger is sending the header, we will get a connection reset, either due to a bad tag (0 is not a valid tag) or a bad header CRC, which kind of defeats the purpose of revoke. Currently the kernel client refuses to work with header CRCs disabled, but that will likely change in the future, making this even worse. (3) con->out_skip is not reset on connection reset, leading to one or more spurious connection resets if we happen to get a real one between con->out_skip is set in ceph_msg_revoke() and before it's cleared in write_partial_skip(). Fixing (1) and (3) is trivial. The idea behind fixing (2) is to never zero the tag or the header, i.e. send out tag+header regardless of when ceph_msg_revoke() is called. That way the header is always correct, no unnecessary resets are induced and revoke stands ready for disabled CRCs. Since ceph_msg_revoke() rips out con->out_msg, introduce a new "message out temp" and copy the header into it before sending.

Support for message signing was merged into 3.19, along with nocephx_require_signatures option. But, all that option does is allow the kernel client to talk to clusters that don't support MSG_AUTH feature bit. That's pretty useless, given that it's been supported since bobtail. Meanwhile, if one disables message signing on the server side with "cephx sign messages = false", it becomes impossible to use the kernel client since it expects messages to be signed if MSG_AUTH was negotiated.

2015-06-25libceph: store timeouts in jiffies, verify user inputIlya Dryomov1-6/+11
There are currently three libceph-level timeouts that the user can specify on mount: mount_timeout, osd_idle_ttl and osdkeepalive. All of these are in seconds and no checking is done on user input: negative values are accepted, we multiply them all by HZ which may or may not overflow, arbitrarily large jiffies then get added together, etc. There is also a bug in the way mount_timeout=0 is handled. It's supposed to mean "infinite timeout", but that's not how wait.h APIs treat it and so __ceph_open_session() for example will busy loop without much chance of being interrupted if none of ceph-mons are there. Fix all this by verifying user input, storing timeouts capped by msecs_to_jiffies() in jiffies and using the new ceph_timeout_jiffies() helper for all user-specified waits to handle infinite timeouts correctly.
