2022-12-16devlink: protect devlink dump by the instance lockJakub Kicinski
Take the instance lock around devlink_nl_fill() when dumping, doit takes it already. We are only dumping basic info so in the worst case we were risking data races around the reload statistics. Until the big devlink mutex was removed all relevant code was protected by it, so the missing instance lock was not exposed.

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux Pull perf tools updates from Arnaldo Carvalho de Melo: "Libraries: - Drop the old copy of libtraceevent in tools/lib/traceevent/ now that all major distros ship it from its external repository. This is now just another feature detection, emitting a warning when the libtraceevent-dev[el] package isn't installed, disabling the build of perf features and tools that strictly require parsing things from tracefs while keeping the core functionality present and working with a subset of the events, the most used ones like CPU cycles, hardware cache and also vendor events, etc. This was tested with lots of containers for Fedora, Debian, OpenSUSE, Alpine Linux, Ubuntu, with cross builds, etc. Build: - Update to C standard to gnu11, like was done for the kernel. - Install the tools/lib/ libraries locally instead of having headers searched directly from the source code directories, to help the cases where we can build either from in-kernel source libraries or from the same library shipped as a distro package, as is the case with libbpf and was the case with libtraceevent. perf stat: - Do not delay the workload with --delay, the delay is just for starting to count the events, to skip noise at workload startup. - When we have events for each cgroup, the metric should be printed for each cgroup separately. $ perf stat -a --for-each-cgroup system.slice,user.slice --metric-only sleep 1 Performance counter stats for 'system wide': GHz insn per cycle branch-misses of all branches system.slice 3.792 0.61 3.24% user.slice 3.661 2.32 0.37% - Fix printing field separator in CSV metrics output. - Fix --metric-only --json output. - Fix summary output in CSV with --metric-only. - Update event group check for support of uncore event. perf test: - Stop requiring a C toolchain in shell tests, instead add a workload option that has all the previously C snippets built as part of 'perf test -w' that then get used in the 'perf test' shell scripts. - Add event group test for events in multiple PMUs - The "kernel lock contention analysis" test should not print warnings in quiet mode. - Add attr tests for ARM64's new VG register. - Fix record test on KVM guests, as using precise flag with the br_inst_retired.near_call event causes the test fail on KVM guests, even when the guests have PMU forwarding enabled and the event itself is supported, so just remove the precise flag from the event. - Add mechanism for skipping attr tests on specific kernel versions where it is known that these checks will fail. - Skip watchpoint tests if no watchpoints available. - Add more Intel PT 'perf test' entries: hybrid CPUs, split the packet decoder into a suite of subtests. perf script: - Introduce task analyzer python script, where one first records some events: Recording can be done in two ways: $ perf script record tasks-analyzer -- sleep 10 $ perf record -e sched:sched_switch -a -- sleep 10 The script can parse any perf.data files, as long as it has sched:sched_switch events, other events will be ignored. The most simple report use case is to just call the script without arguments. Runtime is the time the task was running on the CPU, Time Out-In is the time between the process being scheduled *out* and scheduled back *in*. So the last time span between two executions: $ perf script report tasks-analyzer Switched-In Switched-Out CPU PID TID Comm Runtime Time Out-In 15576.658891407 15576.659156086 4 2412 2428 gdbus 265 1949 15576.659111320 15576.659455410 0 2412 2412 gnome-shell 344 2267 15576.659491326 15576.659506173 2 74 74 kworker/2:1 15 13145 15576.659506173 15576.659825748 2 2858 2858 gnome-terminal- 320 63263 15576.659871270 15576.659902872 6 20932 20932 kworker/u16:0 32 2314582 15576.659909951 15576.659945501 3 27264 27264 sh 36 -1 15576.659853285 15576.659971052 7 27265 27265 perf 118 5050741 [...] perf lock: - Allow concurrent record and report to support live monitoring of kernel lock contention without BPF: # perf lock record -a -o- sleep 1 | perf lock contention -i- contended total wait max wait avg wait type caller 2 10.27 us 6.17 us 5.13 us spinlock load_balance+0xc03 1 5.29 us 5.29 us 5.29 us rwlock:W ep_scan_ready_list+0x54 1 4.12 us 4.12 us 4.12 us spinlock smpboot_thread_fn+0x116 1 3.28 us 3.28 us 3.28 us mutex pipe_read+0x50 - Implement -t/--threads option when using BPF: $ sudo ./perf lock contention -abt -E 5 sleep 1 contended total wait max wait avg wait pid comm 1 740.66 ms 740.66 ms 740.66 ms 1950 nv_queue 3 305.50 ms 298.19 ms 101.83 ms 1884 nvidia-modeset/ 1 25.14 us 25.14 us 25.14 us 2725038 EventManager_De 12 23.09 us 9.30 us 1.92 us 0 swapper 1 20.18 us 20.18 us 20.18 us 2725033 EventManager_De - Add -l/--lock-addr to aggregate per-lock-instance contention: $ sudo ./perf lock contention -abl sleep 1 contended total wait max wait avg wait address symbol 1 36.28 us 36.28 us 36.28 us ffff92615d6448b8 9 10.91 us 1.84 us 1.21 us ffffffffbaed50c0 rcu_state 1 10.49 us 10.49 us 10.49 us ffff9262ac4f0c80 8 4.68 us 1.67 us 585 ns ffffffffbae07a40 jiffies_lock 3 3.03 us 1.45 us 1.01 us ffff9262277861e0 1 924 ns 924 ns 924 ns ffff926095ba9d20 1 436 ns 436 ns 436 ns ffff9260bfda4f60 perf record: - Add remaining branch filters: "no_cycles", "no_flags" & "hw_index", to be used with hardware such as Intel's LBR that allows things like stitching stacks of two samples to overcome the limits of the number of LBR registers. Symbol resolution: - Handle .debug files created with 'objcopy --only-keep-debug', where program headers are zeroed and thus can't be used for adjustments, use the info in the runtime_ss (runtime ELF) instead. perf trace: - Add BPF based augmenter for the 'perf_event_open's 'struct perf_event_attr' argument. - Add BPF based augmenter for the 'clock_gettime's 'struct timespec' argument. - In both cases the syscall tracepoint has just the pointer value, we need to hook a BPF program to collect the pointer contents, and then, in userspace, pretty print it in 'perf trace'. perf list: - Introduce JSON output of events. - Streamline how the expression specifying what events should be shown is handled, fixing several corner cases, such as the metric filter that is specified as a glob but was using strstr(). perf probe: - Fix to avoid crashing if DW_AT_decl_file is NULL, coping with clang generating DWARF5 like that. - Use dwarf_attr_integrate() as generic DWARF attr accessor as it supersedes dwarf_attr(), supporting abstact origin DIEs. perf inject: - Set PERF_RECORD_MISC_BUILD_ID_SIZE in the PERF_RECORD_HEADER_BUILD_ID so that perf.data readers can get the real build-id size and avoid trailing zeroes. perf data: - Add tracepoint fields when converting a perf.data file to JSON. arm64: - Fix mksyscalltbl, don't lose syscalls due to sort -nu. - Add Arm Neoverse V2 PMU events. riscv: - Add riscv sbi firmware std event files. - Add Sifive U74 vendor events (JSON) file. - Add some more events and metrics for Alderlake/Alderlake-N.

2022-12-16Fix mismerge due to devnode now taking a 'const *' deviceLinus Torvalds
This was a mismerge of a semantic conflict in my merge of the driver core updates, where commit ff62b8e6588f ("driver core: make struct class.devnode() take a const *") changed the devnode function pointer type. In the meantime, the drm tree I merged earlier had introduced a new use of that in commit 8bf4889762a8 ("drivers/accel: define kconfig and register a new major"). And of course this happens when I'm traveling with my laptop, and thus didn't do a full allmodconfig build between every pull and before pushing my work out. So I only noticed later as I was doing my full build.

2022-12-16of: fdt: Honor CONFIG_CMDLINE* even without /chosen nodeAlexander Sverdlin
I do not read a strict requirement on /chosen node in either ePAPR or in Documentation/devicetree. Help text for CONFIG_CMDLINE and CONFIG_CMDLINE_EXTEND doesn't make their behavior explicitly dependent on the presence of /chosen or the presense of /chosen/bootargs. However the early check for /chosen and bailing out in early_init_dt_scan_chosen() skips CONFIG_CMDLINE handling which is not really related to /chosen node or the particular method of passing cmdline from bootloader. This leads to counterintuitive combinations (assuming CONFIG_CMDLINE_EXTEND=y): a) bootargs="foo", CONFIG_CMDLINE="bar" => cmdline=="foo bar" b) /chosen missing, CONFIG_CMDLINE="bar" => cmdline=="" c) bootargs="", CONFIG_CMDLINE="bar" => cmdline==" bar" Move CONFIG_CMDLINE handling outside of early_init_dt_scan_chosen() so that cases b and c above result in the same cmdline.

For architectures such as s390 and powerpc that do not use irq domains for MSIs, dev->msi.domain is always NULL, so the per-device, per-bus MSI domain is also guaranteed to be NULL.

The assert fails because the PTE was unlocked in text_area_cpu_up_mm(), and never relocked. The PTE page shouldn't be freed, the patching_mm is only used for patching on this CPU, only that single PTE is ever mapped, and it's only unmapped at CPU offline. In fact assert_pte_locked() has a special case to ignore init_mm entirely, and the patching_mm is more-or-less like init_mm, so possibly the check could be skipped for patching_mm too. But for now be conservative, and use the proper PTE accessors at patching time, so that the PTE lock is held while the PTE is used. That also avoids the warning in assert_pte_locked(). With that it's no longer necessary to save the PTE in cpu_patching_context for the mm_patch_enabled() case.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core updates from Greg KH: "Here is the set of driver core and kernfs changes for 6.2-rc1. The "big" change in here is the addition of a new macro, container_of_const() that will preserve the "const-ness" of a pointer passed into it. The "problem" of the current container_of() macro is that if you pass in a "const *", out of it can comes a non-const pointer unless you specifically ask for it. For many usages, we want to preserve the "const" attribute by using the same call. For a specific example, this series changes the kobj_to_dev() macro to use it, allowing it to be used no matter what the const value is. This prevents every subsystem from having to declare 2 different individual macros (i.e. kobj_const_to_dev() and kobj_to_dev()) and having the compiler enforce the const value at build time, which having 2 macros would not do either. The driver for all of this have been discussions with the Rust kernel developers as to how to properly mark driver core, and kobject, objects as being "non-mutable". The changes to the kobject and driver core in this pull request are the result of that, as there are lots of paths where kobjects and device pointers are not modified at all, so marking them as "const" allows the compiler to enforce this. So, a nice side affect of the Rust development effort has been already to clean up the driver core code to be more obvious about object rules. All of this has been bike-shedded in quite a lot of detail on lkml with different names and implementations resulting in the tiny version we have in here, much better than my original proposal. Lots of subsystem maintainers have acked the changes as well.

That will come back for 6.3-rc1, it missed this merge window. - usual xhci updates and enhancements - usb-serial driver updates and support for new devices - other minor USB driver updates All of these have been in linux-next for a while with no reported problems" * tag 'usb-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (153 commits) usb: gadget: uvc: Rename bmInterfaceFlags -> bmInterlaceFlags usb: dwc2: power on/off phy for peripheral mode in dual-role mode usb: dwc2: disable lpm feature on Rockchip SoCs dt-bindings: usb: mtk-xhci: add support for mt7986 usb: dwc3: core: defer probe on ulpi_read_id timeout usb: ulpi: defer ulpi_register on ulpi_read_id timeout usb: misc: onboard_usb_hub: add Genesys Logic GL850G hub support dt-bindings: usb: Add binding for Genesys Logic GL850G hub controller dt-bindings: vendor-prefixes: add Genesys Logic usb: fotg210-udc: fix potential memory leak in fotg210_udc_probe() usb: typec: tipd: Set mode of operation for USB Type-C connector usb: gadget: udc: drop obsolete dependencies on COMPILE_TEST usb: musb: remove extra check in musb_gadget_vbus_draw usb: gadget: uvc: Prevent buffer overflow in setup handler usb: dwc3: qcom: Fix memory leak in dwc3_qcom_interconnect_init usb: typec: wusb3801: fix fwnode refcount leak in wusb3801_probe() usb: storage: Add check for kcalloc USB: sisusbvga: use module_usb_driver() USB: sisusbvga: rename sisusb.c to sisusbvga.c USB: sisusbvga: remove console support ...
2022-12-16arm64: dts: mt8183: Fix Mali GPU clockChen-Yu Tsai
The actual clock feeding into the Mali GPU on the MT8183 is from the clock gate in the MFGCFG block, not CLK_TOP_MFGPLL_CK from the TOPCKGEN block, which itself is simply a pass-through placeholder for the MFGPLL in the APMIXEDSYS block. Fix the hardware description with the correct clock reference.

2022-12-16arm64: dts: mediatek: mt8195-demo: fix the memory size of node secmonMacpaul Lin
The size of device tree node secmon (bl31_secmon_reserved) was incorrect. It should be increased to 2MiB (0x200000). The origin setting will cause some abnormal behavior due to trusted-firmware-a and related firmware didn't load correctly. The incorrect behavior may vary because of different software stacks. For example, it will cause build error in some Yocto project because it will check if there was enough memory to load trusted-firmware-a to the reserved memory. When mt8195-demo.dts sent to the upstream, at that time the size of BL31 was small. Because supported functions and modules in BL31 are basic sets when the board was under early development stage. Now BL31 includes more firmwares of coprocessors and maturer functions so the size has grown bigger in real applications. According to the value reported by customers, we think reserved 2MiB for BL31 might be enough for maybe the following 2 or 3 years.

2022-12-16openvswitch: Fix flow lookup to use unmasked keyEelco Chaudron
The commit mentioned below causes the ovs_flow_tbl_lookup() function to be called with the masked key. However, it's supposed to be called with the unmasked key. This due to the fact that the datapath supports installing wider flows, and OVS relies on this behavior. For example if ipv4(src=1.1.1.1/192.0.0.0, dst=1.1.1.2/192.0.0.0) exists, a wider flow (smaller mask) of ipv4(src=192.1.1.1/128.0.0.0,dst=192.1.1.2/ 128.0.0.0) is allowed to be added. However, if we try to add a wildcard rule, the installation fails: $ ovs-appctl dpctl/add-flow system@myDP "in_port(1),eth_type(0x0800), \ ipv4(src=1.1.1.1/192.0.0.0,dst=1.1.1.2/192.0.0.0,frag=no)" 2 $ ovs-appctl dpctl/add-flow system@myDP "in_port(1),eth_type(0x0800), \ ipv4(src=192.1.1.1/0.0.0.0,dst=49.1.1.2/0.0.0.0,frag=no)" 2 ovs-vswitchd: updating flow table (File exists) The reason is that the key used to determine if the flow is already present in the system uses the original key ANDed with the mask. This results in the IP address not being part of the (miniflow) key, i.e., being substituted with an all-zero value. When doing the actual lookup, this results in the key wrongfully matching the first flow, and therefore the flow does not get installed. This change reverses the commit below, but rather than having the key on the stack, it's allocated. Fixes: 190aa3e77880 ("openvswitch: Fix Frame-size larger than 1024 bytes warning.")
