* posix/ctime: Fix gfid heal on first lookupKotresh HR2018-05-241-1/+2
| | | | | | | | | | | | | | | | | | | | | With ctime feature enabled, the gfid is not healing on first lookup. The fresh file logic depends on ctime and it was fetching from backend instead of xattr with ctime feature enabled. Fixed the same. Also fixed a possible hang with inode lock Backport of: > Patch: https://review.gluster.org/20052 > BUG: 1580532 > Change-Id: I020875c0462b284d6fa0e68304a422fa3d6a3e73 > Signed-off-by: Kotresh HR <khiremat@redhat.com> fixes: bz#1582080 Change-Id: I020875c0462b284d6fa0e68304a422fa3d6a3e73 Signed-off-by: Kotresh HR <khiremat@redhat.com>

| | | | | | | | | | | | This patch uses the ctime posix APIs to get consistent time across replica.

* posix: APIs in posix to get and set time attributesKotresh HR2018-05-061-1/+3
| | | | | | | | | | | | | This is part of the effort to provide consistent time across distribute and replica set for time attributes (ctime, atime, mtime) of the object. This patch contains the APIs to set and get the attributes from on disk and in inode context.

This results in failure of mkdir. Since striped volumes are always created with dht, some tests associated with stripe also fail.

* storage/posix: send proper iatt attributes for the root inodeRaghavendra Bhat2016-03-261-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * changes in posix to send proper iatt attributes for the root directory when ancestry is built. Before posix was filling only the gfid and the inode type in the iatt structure keeping rest of the fields zeros. This was cached by posix-acl and used to send EACCES when some fops came on that object if the uid of the caller is same as the uid of the object on the disk. * getting and setting inode_ctx in function 'posix_acl_ctx_get' is not atomic and can lead to memory leak when there are multiple looups for an inode at same time. This patch fix this problem * Linking an inode in posix_build_ancestry, can cause a race in posix_acl. When parent inode is linked in posix_build_ancestry, and before it reaches posix_acl_readdirp_cbkc, reate/lookup can come on a leaf-inode, as parent-inode-ctx not yet updated in posix_acl_readdirp_cbk, create/lookup can fail with EACCESS.

* access-control : validating context of access control translatorJiffin Tony Thottan2015-07-021-0/+8
| | | | | | | | | | | | | | | | | | | | | | By introduction of new acl conversion from http://review.gluster.org/#/c/9627/, an acl can be set using GF_POSIX_ACL_*_KEY xattrs without notifying the access-control translator. So evenif an acl is set correctly at the backend, it might not work properly because access-control holds wrong acl information in its context about that file. Note : This is a simple workaround. The actual solution consists of three steps: 1.) Use new acl api's for acl conversion. 2.) Move the acl conversion part from access-control translator 3.) Introduces standard acl structures and libaries in access-translator for caching, enforcing purposes.
