2024-05-08ipvs: allow some sysctls in non-init user namespacesAlexander Mikhalitsyn
Let's make all IPVS sysctls writtable even when network namespace is owned by non-initial user namespace. Let's make a few sysctls to be read-only for non-privileged users: - sync_qlen_max - sync_sock_size - run_estimation - est_cpulist - est_nice I'm trying to be conservative with this to prevent introducing any security issues in there. Maybe, we can allow more sysctls to be writable, but let's do this on-demand and when we see real use-case. This patch is motivated by user request in the LXC project [1]. Having this can help with running some Kubernetes [2] or Docker Swarm [3] workloads inside the system containers.

2024-05-08net: stmmac: dwmac-ipq806x: account for rgmii-txid/rxid/id phy-modeChristian Marangi
Currently the ipq806x dwmac driver is almost always used attached to the CPU port of a switch and phy-mode was always set to "rgmii" or "sgmii". Some device came up with a special configuration where the PHY is directly attached to the GMAC port and in those case phy-mode needs to be set to "rgmii-id" to make the PHY correctly work and receive packets. Since the driver supports only "rgmii" and "sgmii" mode, when "rgmii-id" (or variants) mode is set, the mode is rejected and probe fails. Add support also for these phy-modes to correctly setup PHYs that requires delay applied to tx/rx.

2024-05-08net: bridge: switchdev: Improve error message for port_obj_add/del functionsOleksij Rempel
Enhance the error reporting mechanism in the switchdev framework to provide more informative and user-friendly error messages. Following feedback from users struggling to understand the implications of error messages like "failed (err=-28) to add object (id=2)", this update aims to clarify what operation failed and how this might impact the system or network. With this change, error messages now include a description of the failed operation, the specific object involved, and a brief explanation of the potential impact on the system. This approach helps administrators and developers better understand the context and severity of errors, facilitating quicker and more effective troubleshooting. Example of the improved logging: [ 70.516446] ksz-switch spi0.0 uplink: Failed to add Port Multicast Database entry (object id=2) with error: -ENOSPC (-28). [ 70.516446] Failure in updating the port's Multicast Database could lead to multicast forwarding issues. [ 70.516446] Current HW/SW setup lacks sufficient resources. This comprehensive update includes handling for a range of switchdev object IDs, ensuring that most operations within the switchdev framework benefit from clearer error reporting.

2024-05-08appletalk: Improve handling of broadcast packetsVincent Duvert
When a broadcast AppleTalk packet is received, prefer queuing it on the socket whose address matches the address of the interface that received the packet (and is listening on the correct port). Userspace applications that handle such packets will usually send a response on the same socket that received the packet; this fix allows the response to be sent on the correct interface. If a socket matching the interface's address is not found, an arbitrary socket listening on the correct port will be used, if any. This matches the implementation's previous behavior. Fixes atalkd's responses to network information requests when multiple network interfaces are configured to use AppleTalk.

2024-05-08net/ipv4: add tracepoint for icmp_sendPeilin He
Introduce a tracepoint for icmp_send, which can help users to get more detail information conveniently when icmp abnormal events happen. 1. Giving an usecase example: ============================= When an application experiences packet loss due to an unreachable UDP destination port, the kernel will send an exception message through the icmp_send function. By adding a trace point for icmp_send, developers or system administrators can obtain detailed information about the UDP packet loss, including the type, code, source address, destination address, source port, and destination port. This facilitates the trouble-shooting of UDP packet loss issues especially for those network-service applications. 2. Operation Instructions: ========================== Switch to the tracing directory. cd /sys/kernel/tracing Filter for destination port unreachable. echo "type==3 && code==3" > events/icmp/icmp_send/filter Enable trace event. echo 1 > events/icmp/icmp_send/enable 3. Result View: ================ udp_client_erro-11370 [002] ...s.12 124.728002: icmp_send: icmp_send: type=3, code=3.

Oleksij Rempel says: ==================== add DCB and DSCP support for KSZ switches This patch series is aimed at improving support for DCB (Data Center Bridging) and DSCP (Differentiated Services Code Point) on KSZ switches. The main goal is to introduce global DSCP and PCP (Priority Code Point) mapping support, addressing the limitation of KSZ switches not having per-port DSCP priority mapping. This involves extending the DSA framework with new callbacks for managing trust settings for global DSCP and PCP maps. Additionally, we introduce IEEE 802.1q helpers for default configurations, benefiting other drivers too. Change logs are in separate patches.

2024-05-08erofs: add a reserved buffer pool for lz4 decompressionChunhai Guo
This adds a special global buffer pool (in the end) for reserved pages. Using a reserved pool for LZ4 decompression significantly reduces the time spent on extra temporary page allocation for the extreme cases in low memory scenarios. The table below shows the reduction in time spent on page allocation for LZ4 decompression when using a reserved pool. The results were obtained from multi-app launch benchmarks on ARM64 Android devices running the 5.15 kernel with an 8-core CPU and 8GB of memory. In the benchmark, we launched 16 frequently-used apps, and the camera app was the last one in each round. The data in the table is the average time of camera app for each round. After using the reserved pool, there was an average improvement of 150ms in the overall launch time of our camera app, which was obtained from the systrace log. +--------------+---------------+--------------+---------+ | | w/o page pool | w/ page pool | diff | +--------------+---------------+--------------+---------+ | Average (ms) | 3434 | 21 | -99.38% | +--------------+---------------+--------------+---------+ Based on the benchmark logs, 64 pages are sufficient for 95% of scenarios. This value can be adjusted with a module parameter `reserved_pages`. The default value is 0. This pool is currently only used for the LZ4 decompressor, but it can be applied to more decompressors if needed.

It will cost more time if compressed buffers are allocated on demand for low-latency algorithms (like lz4) so EROFS uses per-CPU buffers to keep compressed data if in-place decompression is unfulfilled. While it is kind of wasteful of memory for a device with hundreds of CPUs, and only a small number of CPUs concurrently decompress most of the time. This patch renames it as 'global buffer pool' and makes it configurable. This allows two or more CPUs to share a common buffer to reduce memory occupation.

2024-05-08xsk: use generic DMA sync shortcut instead of a custom oneAlexander Lobakin
XSk infra's been using its own DMA sync shortcut to try avoiding redundant function calls. Now that there is a generic one, remove the custom implementation and rely on the generic helpers. xsk_buff_dma_sync_for_cpu() doesn't need the second argument anymore, remove it.

2024-05-08page_pool: check for DMA sync shortcut earlierAlexander Lobakin
We can save a couple more function calls in the Page Pool code if we check for dma_need_sync() earlier, just when we test pp->p.dma_sync. Move both these checks into an inline wrapper and call the PP wrapper over the generic DMA sync function only when both are true. You can't cache the result of dma_need_sync() in &page_pool, as it may change anytime if an SWIOTLB buffer is allocated or mapped.

2024-05-08KVM: arm64: Use hVHE in pKVM by default on CPUs with VHE supportWill Deacon
The early command line parsing treats "kvm-arm.mode=protected" as an alias for "id_aa64mmfr1.vh=0", forcing the use of nVHE so that the host kernel runs at EL1 with the pKVM hypervisor at EL2. With the introduction of hVHE support in ad744e8cb346 ("arm64: Allow arm64_sw.hvhe on command line"), the hypervisor can run using the EL2+0 translation regime. This is interesting for unusual CPUs that have VH stuck to 1, but also because it opens the possibility of a hypervisor "userspace" in the distant future which could be used to isolate vCPU contexts in the hypervisor (see Marc's talk from KVM Forum 2022 [1]). Repaint the "kvm-arm.mode=protected" alias to map to "arm64_sw.hvhe=1", which will use hVHE on CPUs that support it and remain with nVHE otherwise.

2024-05-08KVM: arm64: Fix hvhe/nvhe early alias parsingWill Deacon
Booting a kernel with "arm64_sw.hvhe=1 kvm-arm.mode=nvhe" on the command-line results in KVM initialising using hVHE, whereas one might expect the latter option to override the former. Fix this by adding "arm64_sw.hvhe=0" to the alias expansion for "kvm-arm.mode=nvhe".
