git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq updates from Thomas Gleixner: "Core: - Exclude managed interrupts in the calculation of interrupts which are targeted to a CPU which is about to be offlined to ensure that there are enough free vectors on the still online CPUs to migrate them over. Managed interrupts do not need to be accounted because they are either shut down on offline or migrated to an already reserved and guaranteed slot on a still online CPU in the interrupts affinity mask. Including managed interrupts is overaccounting and can result in needlessly aborting hibernation on large server machines. - The usual set of small improvements Drivers: - Make the generic interrupt chip implementation handle interrupt domains correctly and initialize the name pointers correctly - Add interrupt affinity setting support to the Renesas RZG2L chip driver. - Prevent registering syscore operations multiple times in the SiFive PLIC chip driver. - Update device tree handling in the NXP Layerscape MSI chip driver" * tag 'irq-core-2023-10-29-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: irqchip/sifive-plic: Fix syscore registration for multi-socket systems irqchip/ls-scfg-msi: Use device_get_match_data() genirq/generic_chip: Make irq_remove_generic_chip() irqdomain aware genirq/matrix: Exclude managed interrupts in irq_matrix_allocated() PCI/MSI: Provide stubs for IMS functions irqchip/renesas-rzg2l: Enhance driver to support interrupt affinity setting genirq/generic-chip: Fix the irq_chip name for /proc/interrupts irqdomain: Annotate struct irq_domain with __counted_by

2023-10-31iommufd: Organize the mock domain alloc functions closer to Joerg's treeJason Gunthorpe1-19/+16
Patches in Joerg's iommu tree to convert the mock driver to use domain_alloc_paging() that clash badly with the way the selftest changes for nesting were structured. Massage the selftest so that it looks closer the code after the domain_alloc_paging() conversion to ease the merge. Change __mock_domain_alloc_paging() into mock_domain_alloc_paging() in the same way as the iommu tree. The merge resolution then trivially takes both and deletes mock_domain_alloc().

Pull misc vfs updates from Christian Brauner: "This contains the usual miscellaneous features, cleanups, and fixes for vfs and individual fses. Features: - Rename and export helpers that get write access to a mount. They are used in overlayfs to get write access to the upper mount. - Print the pretty name of the root device on boot failure. This helps in scenarios where we would usually only print "unknown-block(1,2)". - Add an internal SB_I_NOUMASK flag. This is another part in the endless POSIX ACL saga in a way. When POSIX ACLs are enabled via SB_POSIXACL the vfs cannot strip the umask because if the relevant inode has POSIX ACLs set it might take the umask from there. But if the inode doesn't have any POSIX ACLs set then we apply the umask in the filesytem itself. So we end up with: (1) no SB_POSIXACL -> strip umask in vfs (2) SB_POSIXACL -> strip umask in filesystem The umask semantics associated with SB_POSIXACL allowed filesystems that don't even support POSIX ACLs at all to raise SB_POSIXACL purely to avoid umask stripping. That specifically means NFS v4 and Overlayfs. NFS v4 does it because it delegates this to the server and Overlayfs because it needs to delegate umask stripping to the upper filesystem, i.e., the filesystem used as the writable layer. This went so far that SB_POSIXACL is raised eve on kernels that don't even have POSIX ACL support at all. Stop this blatant abuse and add SB_I_NOUMASK which is an internal superblock flag that filesystems can raise to opt out of umask handling. That should really only be the two mentioned above. It's not that we want any filesystems to do this. Ideally we have all umask handling always in the vfs. - Make overlayfs use SB_I_NOUMASK too. - Now that we have SB_I_NOUMASK, stop checking for SB_POSIXACL in IS_POSIXACL() if the kernel doesn't have support for it. This is a very old patch but it's only possible to do this now with the wider cleanup that was done. - Follow-up work on fake path handling from last cycle. Citing mostly from Amir: When overlayfs was first merged, overlayfs files of regular files and directories, the ones that are installed in file table, had a "fake" path, namely, f_path is the overlayfs path and f_inode is the "real" inode on the underlying filesystem. In v6.5, we took another small step by introducing of the backing_file container and the file_real_path() helper. This change allowed vfs and filesystem code to get the "real" path of an overlayfs backing file. With this change, we were able to make fsnotify work correctly and report events on the "real" filesystem objects that were accessed via overlayfs. This method works fine, but it still leaves the vfs vulnerable to new code that is not aware of files with fake path. A recent example is commit db1d1e8b9867 ("IMA: use vfs_getattr_nosec to get the i_version"). This commit uses direct referencing to f_path in IMA code that otherwise uses file_inode() and file_dentry() to reference the filesystem objects that it is measuring. This contains work to switch things around: instead of having filesystem code opt-in to get the "real" path, have generic code opt-in for the "fake" path in the few places that it is needed. Is it far more likely that new filesystems code that does not use the file_dentry() and file_real_path() helpers will end up causing crashes or averting LSM/audit rules if we keep the "fake" path exposed by default. This change already makes file_dentry() moot, but for now we did not change this helper just added a WARN_ON() in ovl_d_real() to catch if we have made any wrong assumptions. After the dust settles on this change, we can make file_dentry() a plain accessor and we can drop the inode argument to ->d_real(). - Switch struct file to SLAB_TYPESAFE_BY_RCU. This looks like a small change but it really isn't and I would like to see everyone on their tippie toes for any possible bugs from this work. Essentially we've been doing most of what SLAB_TYPESAFE_BY_RCU for files since a very long time because of the nasty interactions between the SCM_RIGHTS file descriptor garbage collection. So extending it makes a lot of sense but it is a subtle change. There are almost no places that fiddle with file rcu semantics directly and the ones that did mess around with struct file internal under rcu have been made to stop doing that because it really was always dodgy.

gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs Pull vfs superblock updates from Christian Brauner: "This contains the work to make block device opening functions return a struct bdev_handle instead of just a struct block_device. The same struct bdev_handle is then also passed to block device closing functions. This allows us to propagate context from opening to closing a block device without having to modify all users everytime. Sidenote, in the future we might even want to try and have block device opening functions return a struct file directly but that's a series on top of this. These are further preparatory changes to be able to count writable opens and blocking writes to mounted block devices. That's a separate piece of work for next cycle and for that we absolutely need the changes to btrfs that have been quietly dropped somehow. Originally the series contained a patch that removed the old blkdev_*() helpers. But since this would've caused needles churn in -next for bcachefs we ended up delaying it. The second piece of work addresses one of the major annoyances about the work last cycle, namely that we required dropping s_umount whenever we used the superblock and fs_holder_ops for a block device. The reason for that requirement had been that in some codepaths s_umount could've been taken under disk->open_mutex (that's always been the case, at least theoretically). For example, on surprise block device removal or media change. And opening and closing block devices required grabbing disk->open_mutex as well. So we did the work and went through the block layer and fixed all those places so that s_umount is never taken under disk->open_mutex. This means no more brittle games where we yield and reacquire s_umount during block device opening and closing and no more requirements where block devices need to be closed. Filesystems don't need to care about this. There's a bunch of other follow-up work such as moving block device freezing and thawing to holder operations which makes it work for all block devices and not just the main block device just as we did for surprise removal. But that is for next cycle.

However in introducing iommufd_test_dirty() it forgot to validate page_size being 0 leading to two possible divide-by-zero problems: one at the beginning when calculating @max and while calculating the IOVA in the XArray PFN tracking list. While at it, validate the length to require non-zero value as well, as we can't be allocating a 0-sized bitmap.
