2020-09-18fuse: Allow fuse_fill_super_common() for submountsMax Reitz
Submounts have their own superblock, which needs to be initialized. However, they do not have a fuse_fs_context associated with them, and the root node's attributes should be taken from the mountpoint's node. Extend fuse_fill_super_common() to work for submounts by making the @ctx parameter optional, and by adding a @submount_finode parameter. (There is a plain "unsigned" in an existing code block that is being indented by this commit. Extend it to "unsigned int" so checkpatch does not complain.)

2020-09-18fuse: split fuse_mount off of fuse_connMax Reitz
We want to allow submounts for the same fuse_conn, but with different superblocks so that each of the submounts has its own device ID. To do so, we need to split all mount-specific information off of fuse_conn into a new fuse_mount structure, so that multiple mounts can share a single fuse_conn. We need to take care only to perform connection-level actions once (i.e. when the fuse_conn and thus the first fuse_mount are established, or when the last fuse_mount and thus the fuse_conn are destroyed). For example, fuse_sb_destroy() must invoke fuse_send_destroy() until the last superblock is released. To do so, we keep track of which fuse_mount is the root mount and perform all fuse_conn-level actions only when this fuse_mount is involved.

2020-09-18fuse: store fuse_conn in fuse_reqMax Reitz
Every fuse_req belongs to a fuse_conn. Right now, we always know which fuse_conn that is based on the respective device, but we want to allow multiple (sub)mounts per single connection, and then the corresponding filesystem is not going to be so trivial to obtain. Storing a pointer to the associated fuse_conn in every fuse_req will allow us to trivially find any request's superblock (and thus filesystem) even then.

2020-09-16nfs: Fix security label length not being resetJeffrey Mitchell
nfs_readdir_page_filler() iterates over entries in a directory, reusing the same security label buffer, but does not reset the buffer's length. This causes decode_attr_security_label() to return -ERANGE if an entry's security label is longer than the previous one's. This error, in nfs4_decode_dirent(), only gets passed up as -EAGAIN, which causes another failed attempt to copy into the buffer. The second error is ignored and the remaining entries do not show up in ls, specifically the getdents64() syscall. Reproduce by creating multiple files in NFS and giving one of the later files a longer security label. ls will not see that file nor any that are added afterwards, though they will exist on the backend. In nfs_readdir_page_filler(), reset security label buffer length before every reuse Signed-off-by: Jeffrey Mitchell <jeffrey.mitchell@starlab.io> Fixes: b4487b935452 ("nfs: Fix getxattr kernel panic and memory overflow") Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
2020-09-16reiserfs: only call unlock_new_inode() if I_NEWEric Biggers
unlock_new_inode() is only meant to be called after a new inode has already been inserted into the hash table. But reiserfs_new_inode() can call it even before it has inserted the inode, triggering the WARNING in unlock_new_inode(). Fix this by only calling unlock_new_inode() if the inode has the I_NEW flag set, indicating that it's in the table.

2020-09-15xfs: deprecate the V4 formatDarrick J. Wong
The V4 filesystem format contains known weaknesses in the on-disk format that make metadata verification diffiult. In addition, the format does not support dates past 2038 and will not be upgraded to do so. We should start the process of retiring the old format to close off attack surfaces and to encourage users to migrate onto V5. Therefore, make XFS V4 support a configurable option. For the first period it will be default Y in case some distributors want to withdraw support early; for the second period it will be default N so that anyone who wishes to continue support can do so; and after that, support will be removed from the kernel. Dates for these events have been added to the upstream kernel. Signed-off-by: Darrick J.

2020-09-15xfs: make sure the rt allocator doesn't run off the endDarrick J. Wong
There's an overflow bug in the realtime allocator. If the rt volume is large enough to handle a single allocation request that is larger than the maximum bmap extent length and the rt bitmap ends exactly on a bitmap block boundary, it's possible that the near allocator will try to check the freeness of a range that extends past the end of the bitmap. This fails with a corruption error and shuts down the fs. Therefore, constrain maxlen so that the range scan cannot run off the end of the rt bitmap. Signed-off-by: Darrick J.
