2024-01-08bnxt_en: Fix RCU locking for ntuple filters in bnxt_rx_flow_steer()Michael Chan1-1/+1
Similar to the previous patch, RCU locking was released too early in bnxt_rx_flow_steer(). Fix it to unlock after reading fltr->base.sw_id to guarantee that fltr won't be freed while we are still reading it.

2024-01-08bnxt_en: Fix RCU locking for ntuple filters in bnxt_srxclsrldel()Michael Chan1-10/+11
After looking up an ntuple filter from a RCU hash list, the rcu_read_unlock() call should be made after reading the structure, or after determining that the filter cannot age out (by aRFS). The existing code was calling rcu_read_unlock() too early in bnxt_srxclsrldel(). As suggested by Simon Horman, change the code to handle the error case of fltr_base not found in the if condition. The code looks cleaner this way. Fixes: 8d7ba028aa9a ("bnxt_en: Add support for ntuple filter deletion by ethtool.")

Pull vfs rw updates from Christian Brauner: "This contains updates from Amir for read-write backing file helpers for stacking filesystems such as overlayfs: - Fanotify is currently in the process of introducing pre content events. Roughly, a new permission event will be added indicating that it is safe to write to the file being accessed. These events are used by hierarchical storage managers to e.g., fill the content of files on first access. During that work we noticed that our current permission checking is inconsistent in rw_verify_area() and remap_verify_area(). Especially in the splice code permission checking is done multiple times. For example, one time for the whole range and then again for partial ranges inside the iterator. In addition, we mostly do permission checking before we call file_start_write() except for a few places where we call it after. For pre-content events we need such permission checking to be done before file_start_write(). So this is a nice reason to clean this all up. After this series, all permission checking is done before file_start_write(). As part of this cleanup we also massaged the splice code a bit. We got rid of a few helpers because we are alredy drowning in special read-write helpers. We also cleaned up the return types for splice helpers. - Introduce generic read-write helpers for backing files.

git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull vfs super updates from Christian Brauner: "This contains the super work for this cycle including the long-awaited series by Jan to make it possible to prevent writing to mounted block devices: - Writing to mounted devices is dangerous and can lead to filesystem corruption as well as crashes. Furthermore syzbot comes with more and more involved examples how to corrupt block device under a mounted filesystem leading to kernel crashes and reports we can do nothing about. Add tracking of writers to each block device and a kernel cmdline argument which controls whether other writeable opens to block devices open with BLK_OPEN_RESTRICT_WRITES flag are allowed. Note that this effectively only prevents modification of the particular block device's page cache by other writers. The actual device content can still be modified by other means - e.g. by issuing direct scsi commands, by doing writes through devices lower in the storage stack (e.g. in case loop devices, DM, or MD are involved) etc. But blocking direct modifications of the block device page cache is enough to give filesystems a chance to perform data validation when loading data from the underlying storage and thus prevent kernel crashes. Syzbot can use this cmdline argument option to avoid uninteresting crashes. Also users whose userspace setup does not need writing to mounted block devices can set this option for hardening. We expect that this will be interesting to quite a few workloads. Btrfs is currently opted out of this because they still haven't merged patches we require for this to work from three kernel releases ago. - Reimplement block device freezing and thawing as holder operations on the block device. This allows us to extend block device freezing to all devices associated with a superblock and not just the main device. It also allows us to remove get_active_super() and thus another function that scans the global list of superblocks. Freezing via additional block devices only works if the filesystem chooses to use @fs_holder_ops for these additional devices as well. That currently only includes ext4 and xfs. Earlier releases switched get_tree_bdev() and mount_bdev() to use @fs_holder_ops. The remaining nilfs2 open-coded version of mount_bdev() has been converted to rely on @fs_holder_ops as well. So block device freezing for the main block device will continue to work as before. There should be no regressions in functionality. The only special case is btrfs where block device freezing for the main block device never worked because sb->s_bdev isn't set. Block device freezing for btrfs can be fixed once they can switch to @fs_holder_ops but that can happen whenever they're ready" * tag 'vfs-6.8.super' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (27 commits) block: Fix a memory leak in bdev_open_by_dev() super: don't bother with WARN_ON_ONCE() super: massage wait event mechanism ext4: Block writes to journal device xfs: Block writes to log device fs: Block writes to mounted block devices btrfs: Do not restrict writes to btrfs devices block: Add config option to not allow writing to mounted devices block: Remove blkdev_get_by_*() functions bcachefs: Convert to bdev_open_by_path() fs: handle freezing from multiple devices fs: remove dead check nilfs2: simplify device handling fs: streamline thaw_super_locked ext4: simplify device handling xfs: simplify device handling fs: simplify setup_bdev_super() calls blkdev: comment fs_holder_ops porting: document block device freeze and thaw changes fs: remove unused helper ...

2024-01-08PCI: xilinx-xdma: Fix error code in xilinx_pl_dma_pcie_init_irq_domain()Harshit Mogalapalli1-1/+1
Currently, if the function irq_domain_add_linear() fails to allocate a new IRQ domain and returns NULL, we would then still return a success from the xilinx_pl_dma_pcie_init_irq_domain() function regardless, as the PTR_ERR(NULL) would return a value of zero. This is not a desirable outcome. Thus, fix the incorrect error code and return the -ENOMEM error code if the irq_domain_add_linear() fails to allocate a new IRQ domain.

2024-01-08hwmon: (gigabyte_waterforce) Mark status report as received under a spinlockAleksa Savic1-0/+2
Through hidraw, userspace can cause a status report to be sent from the device. The parsing in waterforce_raw_event() may happen in parallel to a waterforce_get_status() call (which resets the completion for tracking the report) if it's running on a different CPU where bottom half interrupts are not disabled. Add a spinlock around the complete_all() call in waterforce_raw_event() to prevent race issues.
