We don't set SB_I_VERSION on ceph since we need to manage it ourselves, so we must increment it whenever we update the file times. Signed-off-by:

Under ceph, clients can be independently updating iversion themselves, while working under comprehensive sets of caps on an inode. In that situation we always want to prefer the largest value of a change attribute. Add a new function that will update a raw value with a larger one, but otherwise leave it alone. Signed-off-by:

...ditto for the decode function. We only use these functions to fix up banner addresses now, so let's name them more appropriately. Signed-off-by:

Going forward, we'll have different address types so let's use the addr2 TYPE_LEGACY for internal tracking rather than TYPE_NONE. Also, make ceph_pr_addr print the address type value as well. Signed-off-by:

Given the new format, we have to decode the addresses twice. Once to skip past the new_up_client field, and a second time to collect the addresses. Signed-off-by:

Add a function for decoding an entity_addr_t. Once CEPH_FEATURE_MSG_ADDR2 is enabled, the server daemons will start encoding entity_addr_t differently. Add a new helper function that can handle either format. Signed-off-by:

handle_cap_export() may add placeholder caps to session that is in opening state. These caps' session pointer become wild after session get unregistered. The fix is not to unregister session in opening state during mds failovers, just let client to reconnect later when mds is recovered. Link: https://tracker.ceph.com/issues/40190Signed-off-by:

When creating new file/directory, use security_dentry_init_security() to prepare selinux context for the new inode, then send openc/mkdir request to MDS, together with selinux xattr. security_dentry_init_security() only supports single security module and only selinux has dentry_init_security hook. So only selinux is supported for now. We can add support for other security modules once kernel has a generic version of dentry_init_security() Signed-off-by:

Also rename ceph_release_acls_info() to ceph_release_acl_sec_ctx(). And move their definitions to different files. This is preparation for security label support. Signed-off-by:

d_name_cmp() and update_dentry_lease() lock and unlock dentry->d_lock respectively. Dentry may get renamed between them. The fix is moving the dentry name compare into update_dentry_lease(). This patch introduce two version of update_dentry_lease(). One version is for the case that parent inode is locked. It does not need to check parent/target inode and dentry name. Another version is for the case that parent inode is not locked. It checks parent/target inode and dentry name after locking dentry->d_lock. Signed-off-by:

This barrier only applies to the read-modify-write operations; in particular, it does not apply to the atomic64_set() primitive. Replace the barrier with an smp_mb(). Fixes: fdd4e158 ("ceph: rework dcache readdir") Reported-by:

The vxattr value incorrectly places a "09" prefix to the nanoseconds field, instead of providing it as a zero-pad width specifier after '%'. Fixes: 3489b42a ("ceph: fix three bugs, two in ceph_vxattrcb_file_layout()") Link: https://tracker.ceph.com/issues/39943Signed-off-by:

ceph_listxattr() now calculates the length of vxattrs dynamically, so these helpers, which incorrectly ignore vxattr.exists_cb(), can be removed. Signed-off-by:
-
David Disseldorp authored
ceph_listxattr() incorrectly returns a length based on the static ceph_vxattrs_name_size() value, which only takes into account whether vxattrs are hidden, ignoring vxattr.exists_cb(). When filling the xattr buffer ceph_listxattr() checks VXATTR_FLAG_HIDDEN and vxattr.exists_cb(). If both are false, we return an incorrect (oversize) length. Fix this behaviour by always calculating the vxattrs length at runtime, taking both vxattr.hidden and vxattr.exists_cb() into account. This bug is only exposed with the new "ceph.snap.btime" vxattr, as all other vxattrs with a non-null exists_cb also carry VXATTR_FLAG_HIDDEN. Signed-off-by:

The problem is that if ceph_mdsc_build_path() fails then we set "path" to NULL and the "pathlen" variable is uninitialized. Then we call ceph_mdsc_free_path(path, pathlen) to clean up. Since "path" is NULL, the function is a no-op but Smatch and UBSan still complain that "pathlen" is uninitialized. This patch doesn't change run time, it just silence the warnings. Signed-off-by:
