2022-03-28Reinstate some of "swiotlb: rework "fix info leak with DMA_FROM_DEVICE""Linus Torvalds
Halil Pasic points out [1] that the full revert of that commit (revert in bddac7c1e02b), and that a partial revert that only reverts the problematic case, but still keeps some of the cleanups is probably better.  And that partial revert [2] had already been verified by Oleksandr Natalenko to also fix the issue, I had just missed that in the long discussion. So let's reinstate the cleanups from commit aa6f8dcbab47 ("swiotlb: rework "fix info leak with DMA_FROM_DEVICE""), and effectively only revert the part that caused problems.

2022-03-26Revert "swiotlb: rework "fix info leak with DMA_FROM_DEVICE""Linus Torvalds
This reverts commit aa6f8dcbab473f3a3c7454b74caa46d36cdc5d13. It turns out this breaks at least the ath9k wireless driver, and possibly others. What the ath9k driver does on packet receive is to set up the DMA transfer with: int ath_rx_init(..) .. bf->bf_buf_addr = dma_map_single(sc->dev, skb->data, common->rx_bufsize, DMA_FROM_DEVICE); and then the receive logic (through ath_rx_tasklet()) will fetch incoming packets static bool ath_edma_get_buffers(..) .. dma_sync_single_for_cpu(sc->dev, bf->bf_buf_addr, common->rx_bufsize, DMA_FROM_DEVICE); ret = ath9k_hw_process_rxdesc_edma(ah, rs, skb->data); if (ret == -EINPROGRESS) { /*let device gain the buffer again*/ dma_sync_single_for_device(sc->dev, bf->bf_buf_addr, common->rx_bufsize, DMA_FROM_DEVICE); return false; } and it's worth noting how that first DMA sync: dma_sync_single_for_cpu(..DMA_FROM_DEVICE); is there to make sure the CPU can read the DMA buffer (possibly by copying it from the bounce buffer area, or by doing some cache flush). The iommu correctly turns that into a "copy from bounce bufer" so that the driver can look at the state of the packets. In the meantime, the device may continue to write to the DMA buffer, but we at least have a snapshot of the state due to that first DMA sync. But that _second_ DMA sync: dma_sync_single_for_device(..DMA_FROM_DEVICE); is telling the DMA mapping that the CPU wasn't interested in the area because the packet wasn't there. In the case of a DMA bounce buffer, that is a no-op. Note how it's not a sync for the CPU (the "for_device()" part), and it's not a sync for data written by the CPU (the "DMA_FROM_DEVICE" part). Or rather, it _should_ be a no-op. That's what commit aa6f8dcbab47 broke: it made the code bounce the buffer unconditionally, and changed the DMA_FROM_DEVICE to just unconditionally and illogically be DMA_TO_DEVICE. [ Side note: purely within the confines of the swiotlb driver it wasn't entirely illogical: The reason it did that odd DMA_FROM_DEVICE -> DMA_TO_DEVICE conversion thing is because inside the swiotlb driver, it uses just a swiotlb_bounce() helper that doesn't care about the whole distinction of who the sync is for - only which direction to bounce. So it took the "sync for device" to mean that the CPU must have been the one writing, and thought it meant DMA_TO_DEVICE. ] Also note how the commentary in that commit was wrong, probably due to that whole confusion, claiming that the commit makes the swiotlb code "bounce unconditionally (that is, also when dir == DMA_TO_DEVICE) in order do avoid synchronising back stale data from the swiotlb buffer" which is nonsensical for two reasons: - that "also when dir == DMA_TO_DEVICE" is nonsensical, as that was exactly when it always did - and should do - the bounce. - since this is a sync for the device (not for the CPU), we're clearly fundamentally not coping back stale data from the bounce buffers at all, because we'd be copying *to* the bounce buffers. So that commit was just very confused. It confused the direction of the synchronization (to the device, not the cpu) with the direction of the DMA (from the device).

2022-03-24kasan: documentation updatesAndrey Konovalov
Update KASAN documentation: - Bump Clang version requirement for HW_TAGS as ARM64_MTE depends on AS_HAS_LSE_ATOMICS as of commit 2decad92f4731 ("arm64: mte: Ensure TIF_MTE_ASYNC_FAULT is set atomically"), which requires Clang 12. - Add description of the new kasan.vmalloc command line flag. - Mention that SW_TAGS and HW_TAGS modes now support vmalloc tagging. - Explicitly say that the "Shadow memory" section is only applicable to software KASAN modes. - Mention that shadow-based KASAN_VMALLOC is supported on arm64.

2022-03-24tools/vm/page_owner_sort.c: support for user-defined culling rulesJiajian Ye
When viewing page owner information, we may want to cull blocks of information with our own rules. So it is important to enhance culling function to provide the support for customizing culling rules. Therefore, following adjustments are made: 1. Add --cull option to support the culling of blocks of information with user-defined culling rules. ./page_owner_sort <input> <output> --cull=<rules> ./page_owner_sort <input> <output> --cull <rules> <rules> is a single argument in the form of a comma-separated list to specify individual culling rules, by the sequence of keys k1,k2, .... Mixed use of abbreviated and complete-form of keys is allowed. For reference, please see the document(Documentation/vm/page_owner.rst). Now, assuming two blocks in the input file are as follows: Page allocated via order 0, mask xxxx, pid 1, tgid 1 (task_name_demo) PFN xxxx prep_new_page+0xd0/0xf8 get_page_from_freelist+0x4a0/0x1290 __alloc_pages+0x168/0x340 alloc_pages+0xb0/0x158 Page allocated via order 0, mask xxxx, pid 32, tgid 32 (task_name_demo) PFN xxxx prep_new_page+0xd0/0xf8 get_page_from_freelist+0x4a0/0x1290 __alloc_pages+0x168/0x340 alloc_pages+0xb0/0x158 If we want to cull the blocks by stacktrace and task command name, we can use this command: ./page_owner_sort <input> <output> --cull=stacktrace,name The output would be like: 2 times, 2 pages, task_comm_name: task_name_demo prep_new_page+0xd0/0xf8 get_page_from_freelist+0x4a0/0x1290 __alloc_pages+0x168/0x340 alloc_pages+0xb0/0x158 As we can see, these two blocks are culled successfully, for they share the same pid and task command name. However, if we want to cull the blocks by pid, stacktrace and task command name, we can this command: ./page_owner_sort <input> <output> --cull=stacktrace,name,pid The output would be like: 1 times, 1 pages, PID 1, task_comm_name: task_name_demo prep_new_page+0xd0/0xf8 get_page_from_freelist+0x4a0/0x1290 __alloc_pages+0x168/0x340 alloc_pages+0xb0/0x158 1 times, 1 pages, PID 32, task_comm_name: task_name_demo prep_new_page+0xd0/0xf8 get_page_from_freelist+0x4a0/0x1290 __alloc_pages+0x168/0x340 alloc_pages+0xb0/0x158 As we can see, these two blocks are failed to cull, for their PIDs are different. 2. Add explanations of --cull options to the document.

command name When viewing page owner information, we may also need to select the blocks by PID, TGID or task command name, which helps to get more accurate page allocation information as needed. Therefore, following adjustments are made: 1. Add three new options, including --pid, --tgid and --name, to support the selection of information blocks by a specific pid, tgid and task command name. In addtion, multiple options are allowed to be used at the same time. ./page_owner_sort [input] [output] --pid <PID> ./page_owner_sort [input] [output] --tgid <TGID> ./page_owner_sort [input] [output] --name <TASK_COMMAND_NAME> Assuming a scenario when a multi-threaded program, ./demo (PID = 5280), is running, and ./demo creates a child process (PID = 5281). $ps PID TTY TIME CMD 5215 pts/0 00:00:00 bash 5280 pts/0 00:00:00 ./demo 5281 pts/0 00:00:00 ./demo 5282 pts/0 00:00:00 ps It would be better to filter out the records with tgid=5280 and the task name "demo" when debugging the parent process, and the specific usage is ./page_owner_sort [input] [output] --tgid 5280 --name demo 2.

This is more foundational infrastructure in preparation for dynamic memory region provisioning support. Recall that CXL memory regions, as the new "Theory of Operation" section of Documentation/driver-api/cxl/memory-devices.rst describes, bring storage volume striping semantics to memory.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "The sprinkling of SPI drivers is because we added a new one and Mark sent us a SPI driver interface conversion pull request. Core ---- - Introduce XDP multi-buffer support, allowing the use of XDP with jumbo frame MTUs and combination with Rx coalescing offloads (LRO). - Speed up netns dismantling (5x) and lower the memory cost a little. Remove unnecessary per-netns sockets. Scope some lists to a netns. Cut down RCU syncing. Use batch methods. Allow netdev registration to complete out of order. - Support distinguishing timestamp types (ingress vs egress) and maintaining them across packet scrubbing points (e.g. redirect). - Continue the work of annotating packet drop reasons throughout the stack. - Switch netdev error counters from an atomic to dynamically allocated per-CPU counters. - Rework a few preempt_disable(), local_irq_save() and busy waiting sections problematic on PREEMPT_RT. - Extend the ref_tracker to allow catching use-after-free bugs. BPF --- - Introduce "packing allocator" for BPF JIT images. JITed code is marked read only, and used to be allocated at page granularity. Custom allocator allows for more efficient memory use, lower iTLB pressure and prevents identity mapping huge pages from getting split. - Make use of BTF type annotations (e.g. __user, __percpu) to enforce the correct probe read access method, add appropriate helpers. - Convert the BPF preload to use light skeleton and drop the user-mode-driver dependency. - Allow XDP BPF_PROG_RUN test infra to send real packets, enabling its use as a packet generator. - Allow local storage memory to be allocated with GFP_KERNEL if called from a hook allowed to sleep. - Introduce fprobe (multi kprobe) to speed up mass attachment (arch bits to come later). - Add unstable conntrack lookup helpers for BPF by using the BPF kfunc infra. - Allow cgroup BPF progs to return custom errors to user space. - Add support for AF_UNIX iterator batching. - Allow iterator programs to use sleepable helpers. - Support JIT of add, and, or, xor and xchg atomic ops on arm64. - Add BTFGen support to bpftool which allows to use CO-RE in kernels without BTF info. - Large number of libbpf API improvements, cleanups and deprecations. Protocols --------- - Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev. - Adjust TSO packet sizes based on min_rtt, allowing very low latency links (data centers) to always send full-sized TSO super-frames. - Make IPv6 flow label changes (AKA hash rethink) more configurable, via sysctl and setsockopt. Distinguish between server and client behavior. - VxLAN support to "collect metadata" devices to terminate only configured VNIs. This is similar to VLAN filtering in the bridge. - Support inserting IPv6 IOAM information to a fraction of frames. - Add protocol attribute to IP addresses to allow identifying where given address comes from (kernel-generated, DHCP etc.) - Support setting socket and IPv6 options via cmsg on ping6 sockets. - Reject mis-use of ECN bits in IP headers as part of DSCP/TOS.

2022-03-23panic: move panic_print before kmsg dumpersGuilherme G. Piccoli
The panic_print setting allows users to collect more information in a panic event, like memory stats, tasks, CPUs backtraces, etc. This is an interesting debug mechanism, but currently the print event happens *after* kmsg_dump(), meaning that pstore, for example, cannot collect a dmesg with the panic_print extra information. This patch changes that in 2 steps: (a) The panic_print setting allows to replay the existing kernel log buffer to the console (bit 5), besides the extra information dump. This functionality makes sense only at the end of the panic() function. So, we hereby allow to distinguish the two situations by a new boolean parameter in the function panic_print_sys_info(). (b) With the above change, we can safely call panic_print_sys_info() before kmsg_dump(), allowing to dump the extra information when using pstore or other kmsg dumpers. The additional messages from panic_print could overwrite the oldest messages when the buffer is full. The only reasonable solution is to use a large enough log buffer, hence we added an advice into the kernel parameters documentation about that.

2022-03-23panic: add option to dump all CPUs backtraces in panic_printGuilherme G. Piccoli
Currently the "panic_print" parameter/sysctl allows some interesting debug information to be printed during a panic event. This is useful for example in cases the user cannot kdump due to resource limits, or if the user collects panic logs in a serial output (or pstore) and prefers a fast reboot instead of a kdump. Happens that currently there's no way to see all CPUs backtraces in a panic using "panic_print" on architectures that support that. We do have "oops_all_cpu_backtrace" sysctl, but although partially overlapping in the functionality, they are orthogonal in nature: "panic_print" is a panic tuning (and we have panics without oopses, like direct calls to panic() or maybe other paths that don't go through oops_enter() function), and the original purpose of "oops_all_cpu_backtrace" is to provide more information on oopses for cases in which the users desire to continue running the kernel even after an oops, i.e., used in non-panic scenarios. So, we hereby introduce an additional bit for "panic_print" to allow dumping the CPUs backtraces during a panic event.

2022-03-23docs: sysctl/kernel: add missing bit to panic_printGuilherme G. Piccoli
Patch series "Some improvements on panic_print". This is a mix of a documentation fix with some additions to the "panic_print" syscall / parameter. The goal here is being able to collect all CPUs backtraces during a panic event and also to enable "panic_print" in a kdump event - details of the reasoning and design choices in the patches. This patch (of 3): Commit de6da1e8bcf0 ("panic: add an option to replay all the printk message in buffer") added a new bit to the sysctl/kernel parameter "panic_print", but the documentation was added only in kernel-parameters.txt, not in the sysctl guide. Fix it here by adding bit 5 to sysctl admin-guide documentation.
