2025-05-29mailbox: qcom-apcs-ipc: Assign OF node to clock controller child deviceStephan Gerhold
Currently, the child device for the clock controller inside the APCS block is created without any OF node assigned, so the drivers need to rely on the parent device for obtaining any resources. Add support for defining the clock controller inside a "clock-controller" subnode to break up circular dependencies between the mailbox and required parent clocks of the clock controller. For backwards compatibility, if the subnode is not defined, reuse the OF node from the parent device.

2025-05-29dt-bindings: mailbox: qcom,apcs: Add separate node for clock-controllerStephan Gerhold
APCS "global" is sort of a "miscellaneous" hardware block that combines multiple registers inside the application processor subsystem. Two distinct use cases are currently stuffed together in a single device tree node: - Mailbox: to communicate with other remoteprocs in the system. - Clock: for controlling the CPU frequency. These two use cases have unavoidable circular dependencies: the mailbox is needed as early as possible during boot to start controlling shared resources like clocks and power domains, while the clock controller needs one of these shared clocks as its parent. Currently, there is no way to distinguish these two use cases for generic mechanisms like fw_devlink. This is currently blocking conversion of the deprecated custom "qcom,ipc" properties to the standard "mboxes", see e.g. commit d92e9ea2f0f9 ("arm64: dts: qcom: msm8939: revert use of APCS mbox for RPM"): 1. remoteproc &rpm needs mboxes = <&apcs1_mbox 8>; 2. The clock controller inside &apcs1_mbox needs clocks = <&rpmcc RPM_SMD_XO_CLK_SRC>. 3. &rpmcc is a child of remoteproc &rpm The mailbox itself does not need any clocks and should probe early to unblock the rest of the boot process. The "clocks" are only needed for the separate clock controller. In Linux, these are already two separate drivers that can probe independently. Break up the circular dependency chain in the device tree by separating the clock controller into a separate child node. Deprecate the old approach of specifying the clock properties as part of the root node, but keep them for backwards compatibility.

2025-05-29acpi-cpufreq: Fix nominal_freq units to KHz in get_max_boost_ratio()Gautham R. Shenoy
commit 083466754596 ("cpufreq: ACPI: Fix max-frequency computation") modified get_max_boost_ratio() to return the nominal_freq advertised in the _CPC object. This was for the purposes of computing the maximum frequency. The frequencies advertised in _CPC objects are in MHz. However, cpufreq expects the frequency to be in KHz. Since the nominal_freq returned by get_max_boost_ratio() was not in KHz but instead in MHz,the cpuinfo_max_frequency that was computed using this nominal_freq was incorrect and an invalid value which resulted in cpufreq reporting the P0 frequency as the cpuinfo_max_freq. Fix this by converting the nominal_freq to KHz before returning the same from get_max_boost_ratio().

2025-05-29ring-buffer: Simplify functions with __free(kfree) to free allocationsSteven Rostedt
The function rb_allocate_pages() allocates cpu_buffer and on error needs to free it. It has a single return. Use __free(kfree) and return directly on errors and have the return use return_ptr(cpu_buffer). The function alloc_buffer() allocates buffer and on error needs to free it. It has a single return. Use __free(kfree) and return directly on errors and have the return use return_ptr(buffer). The function __rb_map_vma() allocates a temporary array "pages". Have it use __free() and not worry about freeing it when returning.

2025-05-29ring-buffer: Simplify ring_buffer_read_page() with guard()Steven Rostedt
The function ring_buffer_read_page() had two gotos. One was simply returning "ret" and the other was unlocking the reader_lock. There's no reason to use goto to simply return the "ret" variable. Instead just return the value. The jump to the unlocking of the reader_lock can be replaced by guard(raw_spinlock_irqsave)(&cpu_buffer->reader_lock). With these two changes the "ret" variable is no longer used and can be removed. The return value on non-error is what was read and is stored in the "read" variable.

The function ring_buffer_swap_cpu() has a bunch of jumps to the label out that simply returns "ret". There's no reason to jump to a label that simply returns a value. Just return directly from there.

2025-05-29tracing: Reset last-boot buffers when reading out all cpu buffersMasami Hiramatsu (Google)
Reset the last-boot ring buffers when read() reads out all cpu buffers through trace_pipe/trace_pipe_raw. This prevents ftrace to unwind ring buffer read pointer next boot. Note that this resets only when all per-cpu buffers are empty, and read via read(2) syscall. For example, if you read only one of the per-cpu trace_pipe, it does not reset it. Also, reading buffer by splice(2) syscall does not reset because some data in the reader (the last) page.

2025-05-29ring-buffer: Allow reserve_mem persistent ring buffers to be mmappedSteven Rostedt
When the persistent ring buffer is created from the memory returned by reserve_mem there is nothing prohibiting it to be memory mapped to user space. The memory is the same as the pages allocated by alloc_page(). The way the memory is managed by the ring buffer code is slightly different though and needs to be addressed. The persistent memory uses the page->id for its own purpose where as the user mmap buffer currently uses that for the subbuf array mapped to user space. If the buffer is a persistent buffer, use the page index into that buffer as the identifier instead of the page->id. That is, the page->id for a persistent buffer, represents the order of the buffer is in the link list. ->id == 0 means it is the reader page. When a reader page is swapped, the new reader page's ->id gets zero, and the old reader page gets the ->id of the page that it swapped with. The user space mapping has the ->id is the index of where it was mapped in user space and does not change while it is mapped. Since the persistent buffer is fixed in its location, the index of where a page is in the memory range can be used as the "id" to put in the meta page array, and it can be mapped in the same order to user space as it is in the persistent memory. A new rb_page_id() helper function is used to get and set the id depending on if the page is a normal memory allocated buffer or a physical memory mapped buffer.

2025-05-29ring-buffer: Do not trigger WARN_ON() due to a commit_overrunSteven Rostedt
When reading a memory mapped buffer the reader page is just swapped out with the last page written in the write buffer. If the reader page is the same as the commit buffer (the buffer that is currently being written to) it was assumed that it should never have missed events. If it does, it triggers a WARN_ON_ONCE(). But there just happens to be one scenario where this can legitimately happen. That is on a commit_overrun. A commit overrun is when an interrupt preempts an event being written to the buffer and then the interrupt adds so many new events that it fills and wraps the buffer back to the commit. Any new events would then be dropped and be reported as "missed_events". In this case, the next page to read is the commit buffer and after the swap of the reader page, the reader page will be the commit buffer, but this time there will be missed events and this triggers the following warning: ------------[ cut here ]------------ WARNING: CPU: 2 PID: 1127 at kernel/trace/ring_buffer.c:7357 ring_buffer_map_get_reader+0x49a/0x780 Modules linked in: kvm_intel kvm irqbypass CPU: 2 UID: 0 PID: 1127 Comm: trace-cmd Not tainted 6.15.0-rc7-test-00004-g478bc2824b45-dirty #564 PREEMPT Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.3-debian-1.16.3-2 04/01/2014 RIP: 0010:ring_buffer_map_get_reader+0x49a/0x780 Code: 00 00 00 48 89 fe 48 c1 ee 03 80 3c 2e 00 0f 85 ec 01 00 00 4d 3b a6 a8 00 00 00 0f 85 8a fd ff ff 48 85 c0 0f 84 55 fe ff ff <0f> 0b e9 4e fe ff ff be 08 00 00 00 4c 89 54 24 58 48 89 54 24 50 RSP: 0018:ffff888121787dc0 EFLAGS: 00010002 RAX: 00000000000006a2 RBX: ffff888100062800 RCX: ffffffff8190cb49 RDX: ffff888126934c00 RSI: 1ffff11020200a15 RDI: ffff8881010050a8 RBP: dffffc0000000000 R08: 0000000000000000 R09: ffffed1024d26982 R10: ffff888126934c17 R11: ffff8881010050a8 R12: ffff888126934c00 R13: ffff8881010050b8 R14: ffff888101005000 R15: ffff888126930008 FS: 00007f95c8cd7540(0000) GS:ffff8882b576e000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f95c8de4dc0 CR3: 0000000128452002 CR4: 0000000000172ef0 Call Trace: <TASK> ? __pfx_ring_buffer_map_get_reader+0x10/0x10 tracing_buffers_ioctl+0x283/0x370 __x64_sys_ioctl+0x134/0x190 do_syscall_64+0x79/0x1c0 entry_SYSCALL_64_after_hwframe+0x76/0x7e RIP: 0033:0x7f95c8de48db Code: 00 48 89 44 24 18 31 c0 48 8d 44 24 60 c7 04 24 10 00 00 00 48 89 44 24 08 48 8d 44 24 20 48 89 44 24 10 b8 10 00 00 00 0f 05 <89> c2 3d 00 f0 ff ff 77 1c 48 8b 44 24 18 64 48 2b 04 25 28 00 00 RSP: 002b:00007ffe037ba110 EFLAGS: 00000246 ORIG_RAX: 0000000000000010 RAX: ffffffffffffffda RBX: 00007ffe037bb2b0 RCX: 00007f95c8de48db RDX: 0000000000000000 RSI: 0000000000005220 RDI: 0000000000000006 RBP: 00007ffe037ba180 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000000000 R11: 0000000000000246 R12: 0000000000000000 R13: 00007ffe037bb6f8 R14: 00007f95c9065000 R15: 00005575c7492c90 </TASK> irq event stamp: 5080 hardirqs last enabled at (5079): [<ffffffff83e0adb0>] _raw_spin_unlock_irqrestore+0x50/0x70 hardirqs last disabled at (5080): [<ffffffff83e0aa83>] _raw_spin_lock_irqsave+0x63/0x70 softirqs last enabled at (4182): [<ffffffff81516122>] handle_softirqs+0x552/0x710 softirqs last disabled at (4159): [<ffffffff815163f7>] __irq_exit_rcu+0x107/0x210 ---[ end trace 0000000000000000 ]--- The above was triggered by running on a kernel with both lockdep and KASAN as well as kmemleak enabled and executing the following command: # perf record -o perf-test.dat -a -- trace-cmd record --nosplice -e all -p function hackbench 50 With perf interjecting a lot of interrupts and trace-cmd enabling all events as well as function tracing, with lockdep, KASAN and kmemleak enabled, it could cause an interrupt preempting an event being written to add enough events to wrap the buffer. trace-cmd was modified to have --nosplice use mmap instead of reading the buffer. The way to differentiate this case from the normal case of there only being one page written to where the swap of the reader page received that one page (which is the commit page), check if the tail page is on the reader page. The difference between the commit page and the tail page is that the tail page is where new writes go to, and the commit page holds the first write that hasn't been committed yet. In the case of an interrupt preempting the write of an event and filling the buffer, it would move the tail page but not the commit page. Have the warning only trigger if the tail page is also on the reader page, and also print out the number of events dropped by a commit overrun as that can not yet be safely added to the page so that the reader can see there were events dropped.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Paolo Abeni: "Core: - Implement the Device Memory TCP transmit path, allowing zero-copy data transmission on top of TCP from e.g. GPU memory to the wire. - Move all the IPv6 routing tables management outside the RTNL scope, under its own lock and RCU. The route control path is now 3x times faster. - Convert queue related netlink ops to instance lock, reducing again the scope of the RTNL lock. This improves the control plane scalability. - Refactor the software crc32c implementation, removing unneeded abstraction layers and improving significantly the related micro-benchmarks. - Optimize the GRO engine for UDP-tunneled traffic, for a 10% performance improvement in related stream tests. - Cover more per-CPU storage with local nested BH locking; this is a prep work to remove the current per-CPU lock in local_bh_disable() on PREMPT_RT. - Introduce and use nlmsg_payload helper, combining buffer bounds verification with accessing payload carried by netlink messages. Netfilter: - Rewrite the procfs conntrack table implementation, improving considerably the dump performance. A lot of user-space tools still use this interface. - Implement support for wildcard netdevice in netdev basechain and flowtables. - Integrate conntrack information into nft trace infrastructure. - Export set count and backend name to userspace, for better introspection. BPF: - BPF qdisc support: BPF-qdisc can be implemented with BPF struct_ops programs and can be controlled in similar way to traditional qdiscs using the "tc qdisc" command. - Refactor the UDP socket iterator, addressing long standing issues WRT duplicate hits or missed sockets. Protocols: - Improve TCP receive buffer auto-tuning and increase the default upper bound for the receive buffer; overall this improves the single flow maximum thoughput on 200Gbs link by over 60%. - Add AFS GSSAPI security class to AF_RXRPC; it provides transport security for connections to the AFS fileserver and VL server. - Improve TCP multipath routing, so that the sources address always matches the nexthop device. - Introduce SO_PASSRIGHTS for AF_UNIX, to allow disabling SCM_RIGHTS, and thus preventing DoS caused by passing around problematic FDs. - Retire DCCP socket. DCCP only receives updates for bugs, and major distros disable it by default. Its removal allows for better organisation of TCP fields to reduce the number of cache lines hit in the fast path. - Extend TCP drop-reason support to cover PAWS checks. Driver API: - Reorganize PTP ioctl flag support to require an explicit opt-in for the drivers, avoiding the problem of drivers not rejecting new unsupported flags. - Converted several device drivers to timestamping APIs. - Introduce per-PHY ethtool dump helpers, improving the support for dump operations targeting PHYs. Tests and tooling: - Add support for classic netlink in user space C codegen, so that ynl-c can now read, create and modify links, routes addresses and qdisc layer configuration. - Add ynl sub-types for binary attributes, allowing ynl-c to output known struct instead of raw binary data, clarifying the classic netlink output. - Extend MPTCP selftests to improve the code-coverage. - Add tests for XDP tail adjustment in AF_XDP.

On arm32, size_t is defined to be unsigned int, while PAGE_SIZE is unsigned long. This hence triggers a compilation warning as min() asserts the type of two operands to be equal. Casting PAGE_SIZE to size_t solves this issue and works on other target architectures as well. Compilation warning details: kernel/trace/trace.c: In function 'tracing_splice_read_pipe': ./include/linux/minmax.h:20:28: warning: comparison of distinct pointer types lacks a cast (!!(sizeof((typeof(x) *)1 == (typeof(y) *)1))) ^ ./include/linux/minmax.h:26:4: note: in expansion of macro '__typecheck' (__typecheck(x, y) && __no_side_effects(x, y)) ^~~~~~~~~~~ ... kernel/trace/trace.c:6771:8: note: in expansion of macro 'min' min((size_t)trace_seq_used(&iter->seq), ^~~ Cc: stable@vger.kernel.org Link: https://lore.kernel.org/20250526013731.1198030-1-pantaixi@huaweicloud.com Fixes: f5178c41bb43 ("tracing: Fix oob write in trace_seq_to_buffer()") Reviewed-by: Jeongjun Park <aha310510@gmail.com> Signed-off-by: Pan Taixi <pantaixi@huaweicloud.com> Signed-off-by: Steven Rostedt (Google) <rostedt@goodmis.org>

Pull nfsd updates from Chuck Lever: "The marquee feature for this release is that the limit on the maximum rsize and wsize has been raised to 4MB. The default remains at 1MB, but risk-seeking administrators now have the ability to try larger I/O sizes with NFS clients that support them. Eventually the default setting will be increased when we have confidence that this change will not have negative impact. With v6.16, NFSD now has its own debugfs file system where we can add experimental features and make them available outside of our development community without impacting production deployments. The first experimental setting added is one that makes all NFS READ operations use vfs_iter_read() instead of the NFSD splice actor. The plan is to eventually retire the splice actor, as that will enable a number of new capabilities such as the use of struct bio_vec from the top to the bottom of the NFSD stack. Jeff Layton contributed a number of observability improvements. The use of dprintk() in a number of high-traffic code paths has been replaced with static trace points. This release sees the continuation of efforts to harden the NFSv4.2 COPY operation. Soon, the restriction on async COPY operations can be lifted.

Pull drm updates from Dave Airlie: "As part of building up nova-core/nova-drm pieces we've brought in some rust abstractions through this tree, aux bus being the main one, with devres changes also in the driver-core tree. Along with the drm core abstractions and enough nova-core/nova-drm to use them. This is still all stub work under construction, to build the nova driver upstream. The other big NVIDIA related one is nouveau adds support for Hopper/Blackwell GPUs, this required a new GSP firmware update to 570.144, and a bunch of rework in order to support multiple fw interfaces. There is also the introduction of an asahi uapi header file as a precursor to getting the real driver in later, but to unblock userspace mesa packages while the driver is trapped behind rust enablement. Otherwise it's the usual mixture of stuff all over, amdgpu, i915/xe, and msm being the main ones, and some changes to vsprintf. new drivers: - bring in the asahi uapi header standalone - nova-drm: stub driver rust dependencies (for nova-core): -
