Ian Kent 43ca440cdf fs: port ->setattr() to pass mnt_idmap ... JIRA: https://issues.redhat.com/browse/RHEL-33888 Status: Linus Conflicts: CentOS Stream commit 3c29fadfb1 ("afs: split afs_pagecache_valid() out of afs_validate()") is present, manually adjust hunk #1 of fs/afs/internal.h. For consistency drop btrfs hunks because it isn't supported in CentOS Stream and other backports also drop such hunks. CentOS Stream commit 48fa94aacd ("ceph: fscrypt_auth handling for ceph") alters the definition of _ceph_setattr(), adjust manually. CentOS Stream commit 34b2a2b5a3 {"ceph: add some fscrypt guardrails") introduces a call to fscrypt_prepare_setattr() which causes fuzz when applying. The cifs source has been moved in CentOS Stream so manually apply rejected hunks to fs/smb/client/cifsfs.h and fs/smb/client/inode.c. Upstream commit 5a646fb3a3e2d ("coda: avoid doing bad things on inode type changes during revalidation") is not present which causes fuzz in fs/coda/coda_linux.h. Dropped hunks for ntfs3 because the source is not present in the CentOS Stream source tree. CentOS Stream commit 98ba731fc7 ("ovl: Move xattr support to new xattrs.c file") is presnt so manually apply hunk. CentOS Stream commit 892da692fa ("shmem: support idmapped mounts for tmpfs") is present so it's ok to pass idmap to setattr_prepare() and setattr_copy(). Update to add incremental changes needed due to CentOS Stream commit 469e1d13f6 ("shmem: quota support"). Allow for CentOS Stream commit 6c3396a0d8 ("kernfs: Introduce separate rwsem to protect inode attributes") which is already present. CentOS Stream commit f5219db0c0 ("KVM: fix Add KVM_CREATE_GUEST_MEMFD ioctl() for guest-specific backing memory") updated the upstream commit a7800aa80ea4d ("KVM: Add KVM_CREATE_GUEST_MEMFD ioctl() for guest-specific backing memory") to account for missing idmapping commits. Now we have updated one of the two places these changes were made make one of the needed adjustments to match the original upstream patch. commit c1632a0f11209338fc300c66252bcc4686e609e8 Author: Christian Brauner <brauner@kernel.org> Date: Fri Jan 13 12:49:11 2023 +0100 fs: port ->setattr() to pass mnt_idmap Convert to struct mnt_idmap. Last cycle we merged the necessary infrastructure in 256c8aed2b42 ("fs: introduce dedicated idmap type for mounts"). This is just the conversion to struct mnt_idmap. Currently we still pass around the plain namespace that was attached to a mount. This is in general pretty convenient but it makes it easy to conflate namespaces that are relevant on the filesystem with namespaces that are relevent on the mount level. Especially for non-vfs developers without detailed knowledge in this area this can be a potential source for bugs. Once the conversion to struct mnt_idmap is done all helpers down to the really low-level helpers will take a struct mnt_idmap argument instead of two namespace arguments. This way it becomes impossible to conflate the two eliminating the possibility of any bugs. All of the vfs and all filesystems only operate on struct mnt_idmap.
