2023-11-24Merge tag 'vfs-6.7-rc3.fixes' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull vfs fixes from Christian Brauner: - Avoid calling back into LSMs from vfs_getattr_nosec() calls. IMA used to query inode properties accessing raw inode fields without dedicated helpers. That was finally fixed a few releases ago by forcing IMA to use vfs_getattr_nosec() helpers. The goal of the vfs_getattr_nosec() helper is to query for attributes without calling into the LSM layer which would be quite problematic because incredibly IMA is called from __fput()... __fput() -> ima_file_free() What it does is to call back into the filesystem to update the file's IMA xattr. Querying the inode without using vfs_getattr_nosec() meant that IMA didn't handle stacking filesystems such as overlayfs correctly. So the switch to vfs_getattr_nosec() is quite correct. But the switch to vfs_getattr_nosec() revealed another bug when used on stacking filesystems: __fput() -> ima_file_free() -> vfs_getattr_nosec() -> i_op->getattr::ovl_getattr() -> vfs_getattr() -> i_op->getattr::$WHATEVER_UNDERLYING_FS_getattr() -> security_inode_getattr() # calls back into LSMs Now, if that __fput() happens from task_work_run() of an exiting task current->fs and various other pointer could already be NULL. So anything in the LSM layer relying on that not being NULL would be quite surprised. Fix that by passing the information that this is a security request through to the stacking filesystem by adding a new internal ATT_GETATTR_NOSEC flag. Now the callchain becomes: __fput() -> ima_file_free() -> vfs_getattr_nosec() -> i_op->getattr::ovl_getattr() -> if (AT_GETATTR_NOSEC) vfs_getattr_nosec() else vfs_getattr() -> i_op->getattr::$WHATEVER_UNDERLYING_FS_getattr() - Fix a bug introduced with the iov_iter rework from last cycle. This broke /proc/kcore by copying too much and without the correct offset. - Add a missing NULL check when allocating the root inode in autofs_fill_super(). - Fix stable writes for multi-device filesystems (xfs, btrfs etc) and the block device pseudo filesystem. Stable writes used to be a superblock flag only, making it a per filesystem property. Add an additional AS_STABLE_WRITES mapping flag to allow for fine-grained control. - Ensure that offset_iterate_dir() returns 0 after reaching the end of a directory so it adheres to getdents() convention. * tag 'vfs-6.7-rc3.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: libfs: getdents() should return 0 after reaching EOD xfs: respect the stable writes flag on the RT device xfs: clean up FS_XFLAG_REALTIME handling in xfs_ioctl_setattr_xflags block: update the stable_writes flag in bdev_add filemap: add a per-mapping stable writes flag autofs: add: new_inode check in autofs_fill_super() iov_iter: fix copy_page_to_iter_nofault() fs: Pass AT_GETATTR_NOSEC flag to getattr interface function

AFS doesn't really do locking on R/O volumes as fileservers don't maintain state with each other and thus a lock on a R/O volume file on one fileserver will not be be visible to someone looking at the same file on another fileserver.

2023-11-24drm: Introduce DRM_CLIENT_CAP_CURSOR_PLANE_HOTSPOTZack Rusin
Virtualized drivers place additional restrictions on the cursor plane which breaks the contract of universal planes. To allow atomic modesettings with virtualized drivers the clients need to advertise that they're capable of dealing with those extra restrictions. To do that introduce DRM_CLIENT_CAP_CURSOR_PLANE_HOTSPOT which lets DRM know that the client is aware of and capable of dealing with the extra restrictions on the virtual cursor plane. Setting this option to true makes DRM expose the cursor plane on virtualized drivers. The userspace is expected to set the hotspots and handle mouse events on that plane.

2023-11-24drm: Disable the cursor plane on atomic contexts with virtualized driversZack Rusin
Cursor planes on virtualized drivers have special meaning and require that the clients handle them in specific ways, e.g. the cursor plane should react to the mouse movement the way a mouse cursor would be expected to and the client is required to set hotspot properties on it in order for the mouse events to be routed correctly. This breaks the contract as specified by the "universal planes". Fix it by disabling the cursor planes on virtualized drivers while adding a foundation on top of which it's possible to special case mouse cursor planes for clients that want it. Disabling the cursor planes makes some kms compositors which were broken, e.g. Weston, fallback to software cursor which works fine or at least better than currently while having no effect on others, e.g. gnome-shell or kwin, which put virtualized drivers on a deny-list when running in atomic context to make them fallback to legacy kms and avoid this issue.

That would mean @size == 0, at which point size_to_bucket() returns -1 and the above happens. alloc_chain_hlocks() has 'size - req', for the first with the precondition 'size >= rq', which allows the 0.

2023-11-23arm64: add dependency between vmlinuz.efi and ImageMasahiro Yamada
A common issue in Makefile is a race in parallel building. You need to be careful to prevent multiple threads from writing to the same file simultaneously. Commit 3939f3345050 ("ARM: 8418/1: add boot image dependencies to not generate invalid images") addressed such a bad scenario. A similar symptom occurs with the following command: $ make -j$(nproc) ARCH=arm64 Image vmlinuz.efi [ snip ] SORTTAB vmlinux OBJCOPY arch/arm64/boot/Image OBJCOPY arch/arm64/boot/Image AS arch/arm64/boot/zboot-header.o PAD arch/arm64/boot/vmlinux.bin GZIP arch/arm64/boot/vmlinuz OBJCOPY arch/arm64/boot/vmlinuz.o LD arch/arm64/boot/vmlinuz.efi.elf OBJCOPY arch/arm64/boot/vmlinuz.efi The log "OBJCOPY arch/arm64/boot/Image" is displayed twice. It indicates that two threads simultaneously enter arch/arm64/boot/ and write to arch/arm64/boot/Image. It occasionally leads to a build failure: $ make -j$(nproc) ARCH=arm64 Image vmlinuz.efi [ snip ] SORTTAB vmlinux OBJCOPY arch/arm64/boot/Image PAD arch/arm64/boot/vmlinux.bin truncate: Invalid number: 'arch/arm64/boot/vmlinux.bin' make[2]: *** [drivers/firmware/efi/libstub/Makefile.zboot:13: arch/arm64/boot/vmlinux.bin] Error 1 make[2]: *** Deleting file 'arch/arm64/boot/vmlinux.bin' make[1]: *** [arch/arm64/Makefile:163: vmlinuz.efi] Error 2 make[1]: *** Waiting for unfinished jobs.... make: *** [Makefile:234: __sub-make] Error 2 vmlinuz.efi depends on Image, but such a dependency is not specified in arch/arm64/Makefile.

We don't support CRUD-inspired message types in YNL too well. One aspect that currently trips us up is the fact that single message ID can be used in multiple commands (as the response).

2023-11-23tls: fix NULL deref on tls_sw_splice_eof() with empty recordJann Horn
syzkaller discovered that if tls_sw_splice_eof() is executed as part of sendfile() when the plaintext/ciphertext sk_msg are empty, the send path gets confused because the empty ciphertext buffer does not have enough space for the encryption overhead. This causes tls_push_record() to go on the `split = true` path (which is only supposed to be used when interacting with an attached BPF program), and then get further confused and hit the tls_merge_open_record() path, which then assumes that there must be at least one populated buffer element, leading to a NULL deref. It is possible to have empty plaintext/ciphertext buffers if we previously bailed from tls_sw_sendmsg_locked() via the tls_trim_both_msgs() path. tls_sw_push_pending_record() already handles this case correctly; let's do the same check in tls_sw_splice_eof().

2023-11-23i40e: Fix adding unsupported cloud filtersIvan Vecera
If a VF tries to add unsupported cloud filter through virtchnl then i40e_add_del_cloud_filter(_big_buf) returns -ENOTSUPP but this error code is stored in 'ret' instead of 'aq_ret' that is used as error code sent back to VF. In this scenario where one of the mentioned functions fails the value of 'aq_ret' is zero so the VF will incorrectly receive a 'success'. Use 'aq_ret' to store return value and remove 'ret' local variable. Additionally fix the issue when filter allocation fails, in this case no notification is sent back to the VF.
