git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull locking updates from Thomas Gleixner: - Move futex code into kernel/futex/ and split up the kitchen sink into seperate files to make integration of sys_futex_waitv() simpler. - Add a new sys_futex_waitv() syscall which allows to wait on multiple futexes. The main use case is emulating Windows' WaitForMultipleObjects which allows Wine to improve the performance of Windows Games. Also native Linux games can benefit from this interface as this is a common wait pattern for this kind of applications. - Add context to ww_mutex_trylock() to provide a path for i915 to rework their eviction code step by step without making lockdep upset until the final steps of rework are completed. It's also useful for regulator and TTM to avoid dropping locks in the non contended path. - Lockdep and might_sleep() cleanups and improvements - A few improvements for the RT substitutions. - The usual small improvements and cleanups. * tag 'locking-core-2021-10-31' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (44 commits) locking: Remove spin_lock_flags() etc locking/rwsem: Fix comments about reader optimistic lock stealing conditions locking: Remove rcu_read_{,un}lock() for preempt_{dis,en}able() locking/rwsem: Disable preemption for spinning region docs: futex: Fix kernel-doc references futex: Fix PREEMPT_RT build futex2: Documentation: Document sys_futex_waitv() uAPI selftests: futex: Test sys_futex_waitv() wouldblock selftests: futex: Test sys_futex_waitv() timeout selftests: futex: Add sys_futex_waitv() test futex,arm: Wire up sys_futex_waitv() futex,x86: Wire up sys_futex_waitv() futex: Implement sys_futex_waitv() futex: Simplify double_lock_hb() futex: Split out wait/wake futex: Split out requeue futex: Rename mark_wake_futex() futex: Rename: match_futex() futex: Rename: hb_waiter_{inc,dec,pending}() futex: Split out PI futex ...

2021-11-01btrfs: fix lzo_decompress_bio() kmap leakageLinus Torvalds1-1/+2
Commit ccaa66c8dd27 reinstated the kmap/kunmap that had been dropped in commit 8c945d32e604 ("btrfs: compression: drop kmap/kunmap from lzo"). However, it seems to have done so incorrectly due to the change not reverting cleanly, and lzo_decompress_bio() ended up not having a matching "kunmap()" to the "kmap()" that was put back. Also, any assert that the page pointer is not NULL should be before the kmap() of said pointer, since otherwise you'd just oops in the kmap() before the assert would even trigger. I noticed this when trying to verify my btrfs merge, and things not adding up. I'm doing this fixup before re-doing my merge, because this commit needs to also be backported to 5.15 (after verification from the btrfs people).

2021-11-01firewire: Remove function callback castsOscar Carter2-10/+33
In 1394 OHCI specification, Isochronous Receive DMA context has several modes. One of mode is 'BufferFill' and Linux FireWire stack uses it to receive isochronous packets for multiple isochronous channel as FW_ISO_CONTEXT_RECEIVE_MULTICHANNEL. The mode is not used by in-kernel driver, while it's available for userspace. The character device driver in firewire-core includes cast of function callback for the mode since the type of callback function is different from the other modes. The case is inconvenient to effort of Control Flow Integrity builds due to -Wcast-function-type warning. This commit removes the cast. A static helper function is newly added to initialize isochronous context for the mode. The helper function arranges isochronous context to assign specific callback function after call of existent kernel API. It's noticeable that the number of isochronous channel, speed, and the size of header are not required for the mode. The helper function is used for the mode by character device driver instead of direct call of existent kernel API. The same goal can be achieved (in the ioctl_create_iso_context function) without this helper function as follows: - Call the fw_iso_context_create function passing NULL to the callback parameter. - Then setting the context->callback.sc or context->callback.mc variables based on the a->type value. However using the helper function created in this patch makes code more clear and declarative. This way avoid the call to a function with one purpose to achieved another one.

2021-11-01Merge tag 'erofs-for-5.16-rc1' of ↵Linus Torvalds25-320/+1281
git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs Pull erofs updates from Gao Xiang: "There are some new features available for this cycle. Firstly, EROFS LZMA algorithm support, specifically called MicroLZMA, is available as an option for embedded devices, LiveCDs and/or as the secondary auxiliary compression algorithm besides the primary algorithm in one file. In order to better support the LZMA fixed-sized output compression, especially for 4KiB pcluster size (which has lowest memory pressure thus useful for memory-sensitive scenarios), Lasse introduced a new LZMA header/container format called MicroLZMA to minimize the original LZMA1 header (for example, we don't need to waste 4-byte dictionary size and another 8-byte uncompressed size, which can be calculated by fs directly, for each pcluster) and enable EROFS fixed-sized output compression. Note that MicroLZMA can also be later used by other things in addition to EROFS too where wasting minimal amount of space for headers is important and it can be only compiled by enabling XZ_DEC_MICROLZMA. MicroLZMA has been supported by the latest upstream XZ embedded [1] & XZ utils [2], apply the latest related XZ embedded upstream patches by the XZ author Lasse here. Secondly, multiple device is also supported in this cycle, which is designed for multi-layer container images. By working together with inter-layer data deduplication and compression, we can achieve the next high-performance container image solution. Our team will announce the new Nydus container image service [3] implementation with new RAFS v6 (EROFS-compatible) format in Open Source Summit 2021 China [4] soon. Besides, the secondary compression head support and readmore decompression strategy are also included in this cycle. There are also some minor bugfixes and cleanups, as always. Summary: - support multiple devices for multi-layer container images; - support the secondary compression head; - support readmore decompression strategy; - support new LZMA algorithm (specifically called MicroLZMA); - some bugfixes & cleanups" * tag 'erofs-for-5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs: erofs: don't trigger WARN() when decompression fails erofs: get rid of ->lru usage erofs: lzma compression support erofs: rename some generic methods in decompressor lib/xz, lib/decompress_unxz.c: Fix spelling in comments lib/xz: Add MicroLZMA decoder lib/xz: Move s->lzma.len = 0 initialization to lzma_reset() lib/xz: Validate the value before assigning it to an enum variable lib/xz: Avoid overlapping memcpy() with invalid input with in-place decompression erofs: introduce readmore decompression strategy erofs: introduce the secondary compression head erofs: get compression algorithms directly on mapping erofs: add multiple device support erofs: decouple basic mount options from fs_context erofs: remove the fast path of per-CPU buffer decompression

2021-11-01selftests, bpf: Fix broken riscv buildBjörn Töpel1-1/+1
This patch is closely related to commit 6016df8fe874 ("selftests/bpf: Fix broken riscv build"). When clang includes the system include directories, but targeting BPF program, __BITS_PER_LONG defaults to 32, unless explicitly set. Work around this problem, by explicitly setting __BITS_PER_LONG to __riscv_xlen.

Clang knows that, but verifier isn't able to infer this relationship. Yonghong Song narrowed down this "regression" in code generation to a recent Clang optimization change ([0]), which for BPF target generates code pattern that BPF verifier can't handle and loses track of register boundaries. This patch works around the issue by adding an BPF assembly-based helper that helps to prove to the verifier that upper bound of the register is a given constant by controlling the exact share of generated BPF instruction sequence. This fixes the immediate issue for strobemeta selftest.

Disabling unprivileged BPF would help prevent unprivileged users from creating certain conditions required for potential speculative execution side-channel attacks on unmitigated affected hardware. A deep dive on such attacks and current mitigations is available here [0]. Sync with what many distros are currently applying already, and disable unprivileged BPF by default.

Pull memory folios from Matthew Wilcox: "Add memory folios, a new type to represent either order-0 pages or the head page of a compound page. This should be enough infrastructure to support filesystems converting from pages to folios. The point of all this churn is to allow filesystems and the page cache to manage memory in larger chunks than PAGE_SIZE. The original plan was to use compound pages like THP does, but I ran into problems with some functions expecting only a head page while others expect the precise page containing a particular byte. The folio type allows a function to declare that it's expecting only a head page. Almost incidentally, this allows us to remove various calls to VM_BUG_ON(PageTail(page)) and compound_head(). This converts just parts of the core MM and the page cache. For 5.17, we intend to convert various filesystems (XFS and AFS are ready; other filesystems may make it) and also convert more of the MM and page cache to folios. For 5.18, multi-page folios should be ready. The multi-page folios offer some improvement to some workloads. The 80% win is real, but appears to be an artificial benchmark (postgres startup, which isn't a serious workload). Real workloads (eg building the kernel, running postgres in a steady state, etc) seem to benefit between 0-10%. I haven't heard of any performance losses as a result of this series. Nobody has done any serious performance tuning; I imagine that tweaking the readahead algorithm could provide some more interesting wins. There are also other places where we could choose to create large folios and currently do not, such as writes that are larger than PAGE_SIZE.

Tony Lu says: ==================== Tracepoints for SMC This patch set introduces tracepoints for SMC, including the tracepoints basic code. The tracepoitns would help us to track SMC's behaviors by automatic tools, or other BPF tools, and zero overhead if not enabled. Compared with kprobe and other dymatic tools, the tracepoints are considered as stable API, and less overhead for tracing with easy-to-use API. ==================== Signed-off-by: David S.

SMC-R link down event is important to help us find links' issues, we should track this event, especially in the single nic mode, which means upper layer connection would be shut down. Then find out the direct link-down reason in time, not only increased the counter, also the location of the code who triggered this event.

Taehee Yoo says: ==================== amt: add initial driver for Automatic Multicast Tunneling (AMT) This is an implementation of AMT(Automatic Multicast Tunneling), RFC 7450. https://datatracker.ietf.org/doc/html/rfc7450 This implementation supports IGMPv2, IGMPv3, MLDv1, MLDv2, and IPv4 underlay. Summary of RFC 7450 The purpose of this protocol is to provide multicast tunneling. The main use-case of this protocol is to provide delivery multicast traffic from a multicast-enabled network to sites that lack multicast connectivity to the source network. There are two roles in AMT protocol, Gateway, and Relay. The main purpose of Gateway mode is to forward multicast listening information(IGMP, MLD) to the source. The main purpose of Relay mode is to forward multicast data to listeners. These multicast traffics(IGMP, MLD, multicast data packets) are tunneled. Listeners are located behind Gateway endpoint. But gateway itself can be a listener too.
