2024-03-11Merge tag 'vfs-6.9.misc' of ↵Linus Torvalds3-11/+9
git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull misc vfs updates from Christian Brauner: "Misc features, cleanups, and fixes for vfs and individual filesystems. Features: - Support idmapped mounts for hugetlbfs. - Add RWF_NOAPPEND flag for pwritev2(). This allows us to fix a bug where the passed offset is ignored if the file is O_APPEND. The new flag allows a caller to enforce that the offset is honored to conform to posix even if the file was opened in append mode. - Move i_mmap_rwsem in struct address_space to avoid false sharing between i_mmap and i_mmap_rwsem. - Convert efs, qnx4, and coda to use the new mount api. - Add a generic is_dot_dotdot() helper that's used by various filesystems and the VFS code instead of open-coding it multiple times. - Recently we've added stable offsets which allows stable ordering when iterating directories exported through NFS on e.g., tmpfs filesystems. Originally an xarray was used for the offset map but that caused slab fragmentation issues over time. This switches the offset map to the maple tree which has a dense mode that handles this scenario a lot better. Includes tests. - Finally merge the case-insensitive improvement series Gabriel has been working on for a long time. This cleanly propagates case insensitive operations through ->s_d_op which in turn allows us to remove the quite ugly generic_set_encrypted_ci_d_ops() operations. It also improves performance by trying a case-sensitive comparison first and then fallback to case-insensitive lookup if that fails. This also fixes a bug where overlayfs would be able to be mounted over a case insensitive directory which would lead to all sort of odd behaviors. Cleanups: - Make file_dentry() a simple accessor now that ->d_real() is simplified because of the backing file work we did the last two cycles. - Use the dedicated file_mnt_idmap helper in ntfs3. - Use smp_load_acquire/store_release() in the i_size_read/write helpers and thus remove the hack to handle i_size reads in the filemap code. - The SLAB_MEM_SPREAD is a nop now. Remove it from various places in fs/ - It's no longer necessary to perform a second built-in initramfs unpack call because we retain the contents of the previous extraction. Remove it. - Now that we have removed various allocators kfree_rcu() always works with kmem caches and kmalloc(). So simplify various places that only use an rcu callback in order to handle the kmem cache case. - Convert the pipe code to use a lockdep comparison function instead of open-coding the nesting making lockdep validation easier. - Move code into fs-writeback.c that was located in a header but can be made static as it's only used in that one file. - Rewrite the alignment checking iterators for iovec and bvec to be easier to read, and also significantly more compact in terms of generated code. This saves 270 bytes of text on x86-64 (with clang-18) and 224 bytes on arm64 (with gcc-13). In profiles it also saves a bit of time for the same workload. - Switch various places to use KMEM_CACHE instead of kmem_cache_create(). - Use inode_set_ctime_to_ts() in inode_set_ctime_current() - Use kzalloc() in name_to_handle_at() to avoid kernel infoleak. - Various smaller cleanups for eventfds. Fixes: - Fix various comments and typos, and unneeded initializations. - Fix stack allocation hack for clang in the select code. - Improve dump_mapping() debug code on a best-effort basis. - Fix build errors in various selftests. - Avoid wrap-around instrumentation in various places. - Don't allow user namespaces without an idmapping to be used for idmapped mounts. - Fix sysv sb_read() call. - Fix fallback implementation of the get_name() export operation" * tag 'vfs-6.9.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (70 commits) hugetlbfs: support idmapped mounts qnx4: convert qnx4 to use the new mount api fs: use inode_set_ctime_to_ts to set inode ctime to current time libfs: Drop generic_set_encrypted_ci_d_ops ubifs: Configure dentry operations at dentry-creation time f2fs: Configure dentry operations at dentry-creation time ext4: Configure dentry operations at dentry-creation time libfs: Add helper to choose dentry operations at mount-time libfs: Merge encrypted_ci_dentry_ops and ci_dentry_ops fscrypt: Drop d_revalidate once the key is added fscrypt: Drop d_revalidate for valid dentries during lookup fscrypt: Factor out a helper to configure the lookup dentry ovl: Always reject mounting over case-insensitive directories libfs: Attempt exact-match comparison first during casefolded lookup efs: remove SLAB_MEM_SPREAD flag usage jfs: remove SLAB_MEM_SPREAD flag usage minix: remove SLAB_MEM_SPREAD flag usage openpromfs: remove SLAB_MEM_SPREAD flag usage proc: remove SLAB_MEM_SPREAD flag usage qnx6: remove SLAB_MEM_SPREAD flag usage ...

2024-03-06dpll: move all dpll<>netdev helpers to dpll codeJakub Kicinski1-1/+1
Older versions of GCC really want to know the full definition of the type involved in rcu_assign_pointer(). struct dpll_pin is defined in a local header, net/core can't reach it. Move all the netdev <> dpll code into dpll, where the type is known. Otherwise we'd need multiple function calls to jump between the compilation units. This is the same problem the commit under fixes was trying to address, but with rcu_assign_pointer() not rcu_dereference(). Some of the exports are not needed, networking core can't be a module, we only need exports for the helpers used by drivers.

2024-02-21docs: Instruct LaTeX to cope with deeper nestingJonathan Corbet1-0/+6
The addition of the XFS online fsck documentation starting with commit a8f6c2e54ddc ("xfs: document the motivation for online fsck design") added a deeper level of nesting than LaTeX is prepared to deal with. That caused a pdfdocs build failure with the helpful "Too deeply nested" error message buried deeply in Documentation/output/filesystems.log. Increase the "maxlistdepth" parameter to instruct LaTeX that it needs to deal with the deeper nesting whether it wants to or not.

2024-02-20x86/bugs: Use ALTERNATIVE() instead of mds_user_clear static keyPawan Gupta1-11/+27
The VERW mitigation at exit-to-user is enabled via a static branch mds_user_clear. This static branch is never toggled after boot, and can be safely replaced with an ALTERNATIVE() which is convenient to use in asm. Switch to ALTERNATIVE() to use the VERW mitigation late in exit-to-user path. Also remove the now redundant VERW in exc_nmi() and arch_exit_to_user_mode().

In control->start(cb) the dpll_lock is taken. Then nlk->cb_mutex is released and taken again in netlink_dump(), while dpll_lock still being held. That leads to ABBA deadlock when another CPU races with the same operation. Fix this by moving dpll_lock taking into dumpit() callback which ensures correct lock taking order.

2024-02-08docs: kernel_feat.py: fix build error for missing filesVegard Nossum1-1/+1
If the directory passed to the '.. kernel-feat::' directive does not exist or the get_feat.pl script does not find any files to extract features from, Sphinx will report the following error: Sphinx parallel build error: UnboundLocalError: local variable 'fname' referenced before assignment make[2]: *** [Documentation/Makefile:102: htmldocs] Error 2 This is due to how I changed the script in c48a7c44a1d0 ("docs: kernel_feat.py: fix potential command injection"). Before that, the filename passed along to self.nestedParse() in this case was weirdly just the whole get_feat.pl invocation. We can fix it by doing what kernel_abi.py does -- just pass self.arguments[0] as 'fname'.

2024-02-06fs: remove the inode argument to ->d_real() methodAmir Goldstein2-10/+8
The only remaining user of ->d_real() method is d_real_inode(), which passed NULL inode argument to get the real data dentry. There are no longer any users that call ->d_real() with a non-NULL inode argument for getting a detry from a specific underlying layer. Remove the inode argument of the method and replace it with an integer 'type' argument, to allow callers to request the real metadata dentry instead of the real data dentry. All the current users of d_real_inode() (e.g. uprobe) continue to get the real data inode. Caller that need to get the real metadata inode (e.g. IMA/EVM) can use d_inode(d_real(dentry, D_REAL_METADATA)).

2024-02-05net: marvell,prestera: Fix example PCI bus addressingRob Herring1-2/+2
The example for PCI devices has some addressing errors. 'reg' is written as if the parent bus is PCI, but the default bus for examples is 1 address and size cell. 'ranges' is defining config space with a size of 0. Generally, config space should not be defined in 'ranges', only PCI memory and I/O spaces. Fix these issues by updating the values with made-up, but valid values. This was uncovered with recent dtschema changes.
