fs/namespace: correctly handle errors returned by grab_requested_mnt_ns

2025-11-24T09:37:37+00:00

[ Upstream commit 78f0e33cd6c939a555aa80dbed2fec6b333a7660 ]

grab_requested_mnt_ns was changed to return error codes on failure, but
its callers were not updated to check for error pointers, still checking
only for a NULL return value.

This commit updates the callers to use IS_ERR() or IS_ERR_OR_NULL() and
PTR_ERR() to correctly check for and propagate errors.

This also makes sure that the logic actually works and mount namespace
file descriptors can be used to refere to mounts.

Christian Brauner  says:

Rework the patch to be more ergonomic and in line with our overall error
handling patterns.

virtio_net: fix alignment for virtio_net_hdr_v1_hash

2025-11-13T20:37:47+00:00

commit c3838262b824c71c145cd3668722e99a69bc9cd9 upstream.

Changing alignment of header would mean it's no longer safe to cast a
2 byte aligned pointer between formats. Use two 16 bit fields to make
it 2 byte aligned as previously.

This fixes the performance regression since
commit ("virtio_net: enable gso over UDP tunnel support.") as it uses
virtio_net_hdr_v1_hash_tunnel which embeds
virtio_net_hdr_v1_hash. Pktgen in guest + XDP_DROP on TAP + vhost_net
shows the TX PPS is recovered from 2.4Mpps to 4.45Mpps.

drm: define NVIDIA DRM format modifiers for GB20x

2025-11-13T20:37:47+00:00

commit 1cf52a0d4ba079fb354fa1339f5fb34142228dae upstream.

The layout of bits within the individual tiles
(referred to as sectors in the
DRM_FORMAT_MOD_NVIDIA_BLOCK_LINEAR_2D() macro)
changed for 8 and 16-bit surfaces starting in
Blackwell 2 GPUs (With the exception of GB10).
To denote the difference, extend the sector field
in the parametric format modifier definition used
to generate modifier values for NVIDIA hardware.

Without this change, it would be impossible to
differentiate the two layouts based on modifiers,
and as a result software could attempt to share
surfaces directly between pre-GB20x and GB20x
cards, resulting in corruption when the surface
was accessed on one of the GPUs after being
populated with content by the other.

Of note: This change causes the
DRM_FORMAT_MOD_NVIDIA_BLOCK_LINEAR_2D() macro to
evaluate its "s" parameter twice, with the side
effects that entails. I surveyed all usage of the
modifier in the kernel and Mesa code, and that
does not appear to be problematic in any current
usage, but I thought it was worth calling out.

HID: hidraw: tighten ioctl command parsing

[ Upstream commit 75d5546f60b36900051d75ee623fceccbeb6750c ]

The handling for variable-length ioctl commands in hidraw_ioctl() is
rather complex and the check for the data direction is incomplete.

Simplify this code by factoring out the various ioctls grouped by dir
and size, and using a switch() statement with the size masked out, to
ensure the rest of the command is correctly matched.

ptp: document behavior of PTP_STRICT_FLAGS

2025-09-22T18:36:30+00:00

Commit 6138e687c7b6 ("ptp: Introduce strict checking of external time stamp
options.") added the PTP_STRICT_FLAGS to the set of flags supported for the
external timestamp request ioctl.

It is only supported by PTP_EXTTS_REQUEST2, as it was introduced the
introduction of the new ioctls. Further, the kernel has always set this
flag for PTP_EXTTS_REQUEST2 regardless of whether or not the user requested
the behavior.

This effectively means that the flag is not useful for userspace. If the
user issues a PTP_EXTTS_REQUEST ioctl, the flag is ignored due to not being
supported on the old ioctl. If the user issues a PTP_EXTTS_REQUEST2 ioctl,
the flag will be set by the kernel regardless of whether the user set the
flag in their structure.

Add a comment documenting this behavior in the uAPI header file.
