2021-11-01dm: add add_disk() error handlingLuis Chamberlain
We never checked for errors on add_disk() as this function returned void. Now that this is fixed, use the shiny new error handling. There are two calls to dm_setup_md_queue() which can fail then, one on dm_early_create() and we can easily see that the error path there calls dm_destroy in the error path. The other use case is on the ioctl table_load case. If that fails userspace needs to call the DM_DEV_REMOVE_CMD to cleanup the state - similar to any other failure.

This patch is closely related to commit 6016df8fe874 ("selftests/bpf: Fix broken riscv build").

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.

2021-11-01bpf: Disallow unprivileged bpf by defaultPawan Gupta
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. An admin can enable this at runtime, if necessary, as described in 08389d888287 ("bpf: Add kconfig knob for disabling unpriv bpf by default").

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v5.16 This is an unusually large set of updates, mostly a large crop of unusually big drivers coupled with extensive overhauls of existing code. There's a SH change here for the DAI format terminology, the change is straightforward and the SH maintainers don't seem very active. - A new version of the audio graph card which supports a wider range of systems. - Move of the Cirrus DSP framework into drivers/firmware to allow for future use by non-audio DSPs. - Several conversions to YAML DT bindings. - Continuing cleanups to the SOF and Intel code. - A very big overhaul of the cs42l42 driver, correcting many problems. - Support for AMD Vangogh and Yelow Cap, Cirrus CS35L41, Maxim MAX98520 and MAX98360A, Mediatek MT8195, Nuvoton NAU8821, nVidia Tegra210, NXP i.MX8ULP, Qualcomm AudioReach, Realtek ALC5682I-VS, RT5682S, and RT9120 and Rockchip RV1126 and RK3568

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. I'd like to thank all my reviewers who've offered review/ack tags: Christoph Hellwig, David Howells, Jan Kara, Jeff Layton, Johannes Weiner, Kirill A. Shutemov, Michal Hocko, Mike Rapoport, Vlastimil Babka, William Kucharski, Yu Zhao and Zi Yan.

There are a lot of warnings due to unused protocol constants, but I believe it's good to leave them in the sources for documentation purposes for further development.

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.

This introduces tracepoint for smc fallback to TCP, so that we can track which connection and why it fallbacks, and map the clcsocks' pointer with /proc/net/tcp to find more details about TCP connections. Compared with kprobe or other dynamic tracing, tracepoints are stable and easy to use.

2021-11-01Merge branch 'amt-driver'David S. Miller
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. Senders are located behind Relay endpoint. ___________ _________ _______ ________ | | | | | | | | | Listeners <-----> Gateway <-----> Relay <-----> Source | |___________| |_________| |_______| |________| IGMP/MLD---------(encap)-----------> <-------------(decap)--------(encap)------Multicast Data Usage of AMT interface 1.
