2019-09-10fuse: rearrange and resize fuse_args fieldsMiklos Szeredi1-2/+2
This makes the structure better packed. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2019-09-10fuse: flatten 'struct fuse_args'Miklos Szeredi1-38/+38
...to make future expansion simpler. The hiearachical structure is a historical thing that does not serve any practical purpose. The generated code is excatly the same before and after the patch. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2018-05-31fuse: Ensure posix acls are translated outside of init_user_nsEric W. Biederman1-0/+43
Ensure the translation happens by failing to read or write posix acls when the filesystem has not indicated it supports posix acls. This ensures that modern cached posix acl support is available and used when dealing with posix acls. This is important because only that path has the code to convernt the uids and gids in posix acls into the user namespace of a fuse filesystem. Signed-off-by: "Eric W.

2016-10-03fuse: limit xattr returned sizeMiklos Szeredi1-2/+2
Don't let userspace filesystem give bogus values for the size of xattr and xattr list. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2016-10-01fuse: Add posix ACL supportSeth Forshee1-5/+13
Add a new INIT flag, FUSE_POSIX_ACL, for negotiating ACL support with userspace. When it is set in the INIT response, ACL support will be enabled. ACL support also implies "default_permissions". When ACL support is enabled, the kernel will cache and have responsibility for enforcing ACLs. ACL xattrs will be passed to userspace, which is responsible for updating the ACLs in the filesystem, keeping the file mode in sync, and inheritance of default ACLs when new filesystem nodes are created.

2016-10-01fuse: Use generic xattr opsSeth Forshee1-0/+203
In preparation for posix acl support, rework fuse to use xattr handlers and the generic setxattr/getxattr/listxattr callbacks. Split the xattr code out into it's own file, and promote symbols to module-global scope as needed. Functionally these changes have no impact, as fuse still uses a single handler for all xattrs which uses the old callbacks.
