libceph: add support for HASHPSPOOL pool flag

2013-02-26T23:03:06Z

The legacy behavior adds the pgid seed and pool together as the input for CRUSH. That is problematic because each pool's PGs end up mapping to the same OSDs: 1.5 == 2.4 == 3.3 == ... Instead, if the HASHPSPOOL flag is set, we has the ps and pool together and feed that into CRUSH. This ensures that two adjacent pools will map to an independent pseudorandom set of OSDs. Advertise our support for this via a protocol feature flag. Signed-off-by: Sage Weil Reviewed-by: Alex Elder

libceph: update osd request/reply encoding

2013-02-26T23:02:50Z

Use the new version of the encoding for osd requests and replies. In the process, update the way we are tracking request ops and reply lengths and results in the struct ceph_osd_request. Update the rbd and fs/ceph users appropriately. The main changes are: - we keep pointers into the request memory for fields we need to update each time the request is sent out over the wire - we keep information about the result in an array in the request struct where the users can easily get at it.

libceph: calculate placement based on the internal data types

2013-02-26T23:02:37Z

Instead of using the old ceph_object_layout struct, update our internal ceph_calc_object_layout method to use the ceph_pg type. This allows us to pass the full 32-bit precision of the pgid.seed to the callers. It also allows some callers to avoid reaching into the request structures for the struct ceph_object_layout fields.

ceph: update support for PGID64, PGPOOL3, OSDENC protocol features

2013-02-26T23:02:25Z

Support (and require) the PGID64, PGPOOL3, and OSDENC protocol features. These have been present in ceph.git since v0.42, Feb 2012. Require these features to simplify support; nobody is running older userspace. Note that the new request and reply encoding is still not in place, so the new code is not yet functional.

ceph: update "ceph_features.h"

2013-02-26T23:02:11Z

This updates "include/linux/ceph/ceph_features.h" so all the feature bits defined in the user space code are defined here. The features supported by this implementation will still differ so that's not updated here. Signed-off-by: Alex Elder Reviewed-by: Sage Weil

libceph: decode into cpu-native ceph_pg type

2013-02-26T23:01:57Z

Always decode data into our cpu-native ceph_pg type that has the correct field widths. Limit any remaining uses of ceph_pg_v1 to dealing with the legacy protocol. Signed-off-by: Sage Weil Reviewed-by: Alex Elder

libceph: rename ceph_pg -> ceph_pg_v1

2013-02-26T23:01:41Z

Rename the old version this type to distinguish it from the new version. Signed-off-by: Sage Weil Reviewed-by: Alex Elder

libceph: drop return value from page vector copy routines

2013-02-20T01:14:05Z

The return values provided for ceph_copy_to_page_vector() and ceph_copy_from_page_vector() serve no purpose, so get rid of them. Signed-off-by: Alex Elder Reviewed-by: Josh Durgin

libceph: use void pointers in page vector functions

2013-02-20T01:14:04Z

The functions used for working with ceph page vectors are defined with char pointers, but they're really intended to operate on untyped data. Change the types of these function parameters to (void *) to reflect this. (Note that the functions now assume void pointer arithmetic works like arithmetic on char pointers.)

libceph: update ceph_fs.h

2013-02-18T18:20:30Z

Update most of "include/linux/ceph/ceph_fs.h" to match its user space counterpart in "src/include/ceph_fs.h" in the ceph tree. Everything that has changed is either: - added definitions (therefore no real effect on existing code) - deleting unused symbols - added or revised comments There were some differences between the struct definitions for ceph_mon_subscribe_item and the open field of ceph_mds_request_args; those differences remain.
