Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client

2016-06-04T18:37:53+00:00

Pull Ceph fixes from Sage Weil:
 "We have a few follow-up fixes for the libceph refactor from Ilya, and
  then some cephfs + fscache fixes from Zheng.

  The first two FS-Cache patches are acked by David Howells and deemed
  trivial enough to go through our tree.  The rest fix some issues with
  the ceph fscache handling (disable cache for inodes opened for write,
  and simplify the revalidation logic accordingly, dropping the
  now-unnecessary work queue)"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client:
  ceph: use i_version to check validity of fscache
  ceph: improve fscache revalidation
  ceph: disable fscache when inode is opened for write
  ceph: avoid unnecessary fscache invalidation/revlidation
  ceph: call __fscache_uncache_page() if readpages fails
  FS-Cache: make check_consistency callback return int
  FS-Cache: wake write waiter after invalidating writes
  libceph: use %s instead of %pE in dout()s
  libceph: put request only if it's done in handle_reply()
  libceph: change ceph_osdmap_flag() to take osdc

fou: fix IPv6 Kconfig options

2016-05-31T21:07:49+00:00

The Kconfig options I added to work around broken compilation ended
up screwing up things more, as I used the wrong symbol to control
compilation of the file, resulting in IPv6 fou support to never be built
into the kernel.

Changing CONFIG_NET_FOU_IPV6_TUNNELS to CONFIG_IPV6_FOU fixes that
problem, I had renamed the symbol in one location but not the other,
and as the file is never being used by other kernel code, this did not
lead to a build failure that I would have caught.

After that fix, another issue with the same patch becomes obvious, as we
'select INET6_TUNNEL', which is related to IPV6_TUNNEL, but not the same,
and this can still cause the original build failure when IPV6_TUNNEL is
not built-in but IPV6_FOU is. The fix is equally trivial, we just need
to select the right symbol.

I have successfully build 350 randconfig kernels with this patch
and verified that the driver is now being built.

openvswitch: update checksum in {push,pop}_mpls

2016-05-31T20:51:42+00:00

In the case of CHECKSUM_COMPLETE the skb checksum should be updated in
{push,pop}_mpls() as they the type in the ethernet header.

As suggested by Pravin Shelar.

sctp: sctp_diag should dump sctp socket type

2016-05-31T18:59:06+00:00

Now we cannot distinguish that one sk is a udp or sctp style when
we use ss to dump sctp_info. it's necessary to dump it as well.

For sctp_diag, ss support is not officially available, thus there
are no official users of this yet, so we can add this field in the
middle of sctp_info without breaking user API.

v1->v2:
  - move 'sctpi_s_type' field to the end of struct sctp_info, so
    that it won't cause incompatibility with applications already
    built.
  - add __reserved3 in sctp_info to make sure sctp_info is 8-byte
    alignment.

vlan: Propagate MAC address to VLANs

2016-05-31T18:56:48+00:00

The MAC address of the physical interface is only copied to the VLAN
when it is first created, resulting in an inconsistency after MAC
address changes of only newly created VLANs having an up-to-date MAC.

The VLANs should continue inheriting the MAC address of the physical
interface until the VLAN MAC address is explicitly set to any value.
This allows IPv6 EUI64 addresses for the VLAN to reflect any changes
to the MAC of the physical interface and thus for DAD to behave as
expected.

2016-05-31T18:44:08+00:00

If CONFIG_DEBUG_OBJECTS_TIMERS=y, hrtimer_init_on_stack() requires
a matching call to destroy_hrtimer_on_stack() to clean up timer
debug objects.

libceph: use %s instead of %pE in dout()s

2016-05-30T21:00:23+00:00

Commit d30291b985d1 ("libceph: variable-sized ceph_object_id") changed
dout()s in what is now encode_request() and ceph_object_locator_to_pg()
to use %pE, mostly to document that, although all rbd and cephfs object
names are NULL-terminated strings, ceph_object_id will handle any RADOS
object name, including the one containing NULs, just fine.

However, it turns out that vbin_printf() can't handle anything but ints
and %s - all %p suffixes are ignored.  The buffer %p** points to isn't
recorded, resulting in trash in the messages if the buffer had been
reused by the time bstr_printf() got to it.

libceph: put request only if it's done in handle_reply()

2016-05-30T21:00:23+00:00

handle_reply() may be called twice on the same request: on ack and then
on commit.  This occurs on btrfs-formatted OSDs or if cephfs sync write
path is triggered - CEPH_OSD_FLAG_ACK | CEPH_OSD_FLAG_ONDISK.

handle_reply() handles this with the help of done_request().

libceph: change ceph_osdmap_flag() to take osdc

2016-05-30T21:00:22+00:00

For the benefit of every single caller, take osdc instead of map.
Also, now that osdc->osdmap can't ever be NULL, drop the check.
