libceph: make DEFINE_RB_* helpers more general

2017-07-07T15:25:17+00:00

Initially for ceph_pg_mapping, ceph_spg_mapping and ceph_hobject_id,
compared with ceph_pg_compare(), ceph_spg_compare() and hoid_compare()
respectively.

libceph: convert ceph_snap_context.nref from atomic_t to refcount_t

2017-05-04T07:19:18+00:00

refcount_t type and corresponding API should be
used instead of atomic_t when the variable is used as
a reference counter. This allows to avoid accidental
refcounter overflows that might lead to use-after-free
situations.

libceph, ceph: always advertise all supported features

2017-05-04T07:19:18+00:00

No reason to hide CephFS-specific features in the rbd case.  Recent
feature bits mix RADOS and CephFS-specific stuff together anyway.

libceph: osd_request_timeout option

2017-03-07T13:30:38+00:00

osd_request_timeout specifies how many seconds to wait for a response
from OSDs before returning -ETIMEDOUT from an OSD request.  0 (default)
means no limit.

osd_request_timeout is osdkeepalive-precise -- in-flight requests are
swept through every osdkeepalive seconds.  With ack vs commit behaviour
gone, abort_request() is really simple.

This is based on a patch from Artur Molchanov .

rbd: add 'client_addr' sysfs rbd device attribute

Export client addr/nonce, so userspace can check if a image is being
blacklisted.

libceph: rename ceph_client_id() -> ceph_client_gid()

It's gid / global_id in other places.

ceph: fix symbol versioning for ceph_monc_do_statfs

2016-07-28T13:32:53+00:00

The genksyms helper in the kernel cannot parse a type definition
like "typeof(((type *)0)->keyfld)" that is used in the DEFINE_RB_FUNCS
helper, causing the following EXPORT_SYMBOL() statement to be ignored
when computing the crcs, and triggering a warning about this:

WARNING: "ceph_monc_do_statfs" [fs/ceph/ceph.ko] has no CRC

To work around the problem, we can rewrite the type to reference
an undefined 'extern' symbol instead of a NULL pointer. This is
evidently ok for genksyms, and it no longer complains about the
line when calling it with 'genksyms -w'.

I've looked briefly into extending genksyms instead, but it seems
really hard to do. Jan Beulich introduced basic support for 'typeof'
a while ago in dc53324060f3 ("genksyms: fix typeof() handling"),
but that is not sufficient for the expression we have here.

libceph: introduce reference counted string

2016-07-28T00:55:37+00:00

The data structure is for storing namesapce string. It allows namespace
string to be shared between cephfs inodes with same layout. This data
structure can also be referenced by OSD request.
