linux-stable.git/fs/ceph, branch v6.10

Merge tag 'ceph-for-6.10-rc1' of https://github.com/ceph/ceph-client

2024-05-25T21:23:58+00:00

Pull ceph updates from Ilya Dryomov:
 "A series from Xiubo that adds support for additional access checks
  based on MDS auth caps which were recently made available to clients.

  This is needed to prevent scenarios where the MDS quietly discards
  updates that a UID-restricted client previously (wrongfully) acked to
  the user.

  Other than that, just a documentation fixup"

ceph: add CEPHFS_FEATURE_MDS_AUTH_CAPS_CHECK feature bit

Since we have support checking the mds auth cap in kclient, just
set the feature bit.

Before doing the op locally we need to check the cephx access.

ceph: add ceph_mds_check_access() helper

2024-05-23T08:35:46+00:00

This will help check the mds auth access in client side. Always
insert the server path in front of the target path when matching
the paths.

netfs: Switch to using unsigned long long rather than loff_t

2024-05-01T17:07:35+00:00

Switch to using unsigned long long rather than loff_t in netfslib to avoid
problems with the sign flipping in the maths when we're dealing with the
byte at position 0x7fffffffffffffff.

mm: Remove the PG_fscache alias for PG_private_2

2024-04-29T14:01:42+00:00

Remove the PG_fscache alias for PG_private_2 and use the latter directly.
Use of this flag for marking pages undergoing writing to the cache should
be considered deprecated and the folios should be marked dirty instead and
the write done in ->writepages().

Note that PG_private_2 itself should be considered deprecated and up for
future removal by the MM folks too.
