include/{topology,cpuset}: Move dl_rebuild_rd_accounting to cpuset.h

2025-04-10T12:44:48+00:00

commit 34929a070b7fd06c386080c926b61ee844e6ad34 upstream.

dl_rebuild_rd_accounting() is defined in cpuset.c, so it makes more
sense to move related declarations to cpuset.h.

Implement the move.

uprobes/x86: Harden uretprobe syscall trampoline check

2025-04-10T12:44:44+00:00

commit fa6192adc32f4fdfe5b74edd5b210e12afd6ecc0 upstream.

Jann reported a possible issue when trampoline_check_ip returns
address near the bottom of the address space that is allowed to
call into the syscall if uretprobes are not set up:

Though the mmap minimum address restrictions will typically prevent
creating mappings there, let's make sure uretprobe syscall checks
for that.

xsk: Add launch time hardware offload support to XDP Tx metadata

2025-04-10T12:44:39+00:00

[ Upstream commit ca4419f15abd19ba8be1e109661b60f9f5b6c9f0 ]

Extend the XDP Tx metadata framework so that user can requests launch time
hardware offload, where the Ethernet device will schedule the packet for
transmission at a pre-determined time called launch time. The value of
launch time is communicated from user space to Ethernet driver via
launch_time field of struct xsk_tx_metadata.

NFSv4: Avoid unnecessary scans of filesystems for delayed delegations

[ Upstream commit e767b59e29b8327d25edde65efc743f479f30d0a ]

The amount of looping through the list of delegations is occasionally
leading to soft lockups. If the state manager was asked to manage the
delayed return of delegations, then only scan those filesystems
containing delegations that were marked as being delayed.
