2025-07-23xen/netfront: Fix TX response spurious interruptsAnthoine Bourgeois
We found at Vates that there are lot of spurious interrupts when benchmarking the xen-net PV driver frontend. This issue appeared with a patch that addresses security issue XSA-391 (b27d47950e48 "xen/netfront: harden netfront against event channel storms"). On an iperf benchmark, spurious interrupts can represent up to 50% of the interrupts. Spurious interrupts are interrupts that are rised for nothing, there is no work to do. This appends because the function that handles the interrupts ("xennet_tx_buf_gc") is also called at the end of the request path to garbage collect the responses received during the transmission load. The request path is doing the work that the interrupt handler should have done otherwise. This is particurary true when there is more than one vcpu and get worse linearly with the number of vcpu/queue. Moreover, this problem is amplifyed by the penalty imposed by a spurious interrupt. When an interrupt is found spurious the interrupt chip will delay the EOI to slowdown the backend. This delay will allow more responses to be handled by the request path and then there will be more chance the next interrupt will not find any work to do, creating a new spurious interrupt. This causes performance issue. The solution here is to remove the calls from the request path and let the interrupt handler do the processing of the responses. This approch removes most of the spurious interrupts (<0.05%) and also has the benefit of freeing up cycles in the request path, allowing it to process more work, which improves performance compared to masking the spurious interrupt one way or another. This optimization changes a part of the code that is present since the net frontend driver was upstreamed. There is no similar pattern in the other xen PV drivers. Since the first commit of xen-netfront is a blob that doesn't explain all the design choices I can only guess why this specific mecanism was here. This could have been introduce to compensate a slow backend at the time (maybe the backend was fixed or optimize later) or a small queue. In 18 years, both frontend and backend gain lot of features and optimizations that could have obsolete the feature of reaping completions from the TX path.

This version doesn't provide the sta id, so we need to look it up - assuming that no other sta exists, since one of the conditions of entering OMI is not having P2P/TDLS. But when we leave OMI, because of the P2P/TDLS activation, the P2P/TDLS sta can already exist while we receive the notification from the FW. This causes an error log which is incorrect.

2025-07-23wifi: iwlwifi: mld: avoid outdated reorder buffer head_snAvraham Stern
If no frames are received on a queue for a while, the reorder buffer head_sn may be an old one. When the next frame that is received on that queue and buffered is a subframe of an AMSDU but not the last subframe, it will not update the buffer's head_sn. When the frame release notification arrives, it will not release the buffered frame because it will look like the notification's NSSN is lower than the buffer's head_sn (because of a wraparound).

2025-07-23uevent: mv uevent_helper into kobject_uevent.cJoel Granados
Move both uevent_helper table into lib/kobject_uevent.c. Place the registration early in the initcall order with postcore_initcall. This is part of a greater effort to move ctl tables into their respective subsystems which will reduce the merge conflicts in kernel/sysctl.c. Signed-off-by: Joel Granados <joel.granados@kernel.org>
2025-07-23sysctl: Removed unused variableJoel Granados
Remove unaligned_dump_stack from sysctl.h; it is no longer used or defined. Signed-off-by: Joel Granados <joel.granados@kernel.org>
2025-07-23sysctl: Nixify sysctl.shJoel Granados
Use "#!/usr/bin/env bash" instead of "#!/bin/bash". Needed for testing in nix environments as they only provide /usr/bin/env at the standard location. Signed-off-by: Joel Granados <joel.granados@kernel.org>
2025-07-23slab: Update MAINTAINERS entryMatthew Wilcox (Oracle)
Add the two Documentation files to the maintainers entry. Simplify the match for header files now that there is only slab.h. Move Vlastimil to the top of the list of maintainers since he's the one doing the pull requests. Change David & Christoph's roles to Reviewer. Expand the pattern for files in mm/ so that somebody searching for 'slub' will find it.

2025-07-23sysctl: Remove (very) old file changelogJoel Granados
These comments are older than 2003 and therefore do not bare any relevance on the current state of the sysctl.c file. Remove them as they confuse more than clarify.

2025-07-23sysctl: move cad_pid into kernel/pid.cJoel Granados
Move cad_pid as well as supporting function proc_do_cad_pid into kernel/pic.c. Replaced call to __do_proc_dointvec with proc_dointvec inside proc_do_cad_pid which requires the copy of the ctl_table to handle the temp value.
