Commit f949a12fd697 ("net: dsa: bcm_sf2: fix buffer overflow doing set_rxnfc") tried to fix the some user controlled buffer overflows in bcm_sf2_cfp_rule_set() and bcm_sf2_cfp_rule_del() but the fix was using CFP_NUM_RULES, which while it is correct not to overflow the bitmaps, is not representative of what the device actually supports. Correct that by using bcm_sf2_cfp_rule_size() instead. The latter subtracts the number of rules by 1, so change the checks from greater than or equal to greater than accordingly.

Packet trap groups are used to aggregate logically related packet traps. Currently, these groups allow user space to batch operations such as setting the trap action of all member traps. In order to prevent the CPU from being overwhelmed by too many trapped packets, it is desirable to bind a packet trap policer to these groups. For example, to limit all the packets that encountered an exception during routing to 10Kpps. Allow device drivers to bind default packet trap policers to packet trap groups when the latter are registered with devlink. The next patch will enable user space to change this default binding.

But that inline helper function was removed in mainline by commit 2c64605b590e ("net: Fix CONFIG_NET_CLS_ACT=n and CONFIG_NFT_FWD_NETDEV={y, m} build"). Fix it by using skb_reset_redirect() instead. Also move it out of the This code path only ends up triggering if REUSE_SKBUFFS_WITHOUT_FREE is enabled, which in turn only happens if you don't have CONFIG_NETFILTER configured.

Specifics: - Clean up and rework the PM QoS API to simplify the code and reduce the size of it (Rafael Wysocki). - Fix a suspend-to-idle wakeup regression on Dell XPS13 9370 and similar platforms where the USB plug/unplug events are handled by the EC (Rafael Wysocki). - CLean up the intel_idle and PSCI cpuidle drivers (Rafael Wysocki, Ulf Hansson). - Extend the haltpoll cpuidle driver so that it can be forced to run on some systems where it refused to load (Maciej Szmigiero). - Convert several cpufreq documents to the .rst format and move the legacy driver documentation into one common file (Mauro Carvalho Chehab, Rafael Wysocki). - Update several cpufreq drivers: * Extend and fix the imx-cpufreq-dt driver (Anson Huang). * Improve the -EPROBE_DEFER handling and fix unwanted CPU overclocking on i.MX6ULL in imx6q-cpufreq (Anson Huang, Christoph Niedermaier). * Add support for Krait based SoCs to the qcom driver (Ansuel Smith). * Add support for OPP_PLUS to ti-cpufreq (Lokesh Vutla). * Add platform specific intermediate callbacks support to cpufreq-dt and update the imx6q driver (Peng Fan). * Simplify and consolidate some pieces of the intel_pstate driver and update its documentation (Rafael Wysocki, Alex Hung). - Fix several devfreq issues: * Remove unneeded extern keyword from a devfreq header file and use the DEVFREQ_GOV_UPDATE_INTERNAL event name instead of DEVFREQ_GOV_INTERNAL (Chanwoo Choi). * Fix the handling of dev_pm_qos_remove_request() result (Leonard Crestez). * Use constant name for userspace governor (Pierre Kuo). * Get rid of doc warnings and fix a typo (Christophe JAILLET). - Use built-in RCU list checking in some places in the PM core to avoid false-positive RCU usage warnings (Madhuparna Bhowmik). - Add explicit READ_ONCE()/WRITE_ONCE() annotations to low-level PM QoS routines (Qian Cai). - Fix removal of wakeup sources to avoid NULL pointer dereferences in a corner case (Neeraj Upadhyay). - Clean up the handling of hibernate compat ioctls and fix the related documentation (Eric Biggers). - Update the idle_inject power capping driver to use variable-length arrays instead of zero-length arrays (Gustavo Silva). - Fix list format in a PM QoS document (Randy Dunlap). - Make the cpufreq stats module use scnprintf() to avoid potential buffer overflows (Takashi Iwai). - Add pm_runtime_get_if_active() to PM-runtime API (Sakari Ailus). - Allow no domain-idle-states DT property in generic PM domains (Ulf Hansson). - Fix a broken y-axis scale in the intel_pstate_tracer utility (Doug Smythies)" * tag 'pm-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (78 commits) cpufreq: intel_pstate: Simplify intel_pstate_cpu_init() tools/power/x86/intel_pstate_tracer: fix a broken y-axis scale ACPI: PM: s2idle: Refine active GPEs check ACPICA: Allow acpi_any_gpe_status_set() to skip one GPE PM: sleep: wakeup: Skip wakeup_source_sysfs_remove() if device is not there PM / devfreq: Get rid of some doc warnings PM / devfreq: Fix handling dev_pm_qos_remove_request result PM / devfreq: Fix a typo in a comment PM / devfreq: Change to DEVFREQ_GOV_UPDATE_INTERVAL event name PM / devfreq: Remove unneeded extern keyword PM / devfreq: Use constant name of userspace governor ACPI: PM: s2idle: Fix comment in acpi_s2idle_prepare_late() cpufreq: qcom: Add support for krait based socs cpufreq: imx6q-cpufreq: Improve the logic of -EPROBE_DEFER handling cpufreq: Use scnprintf() for avoiding potential buffer overflow cpuidle: psci: Split psci_dt_cpu_init_idle() PM / Domains: Allow no domain-idle-states DT property in genpd when parsing PM / hibernate: Remove unnecessary compat ioctl overrides PM: hibernate: fix docs for ioctls that return loff_t via pointer Documentation: intel_pstate: update links for references ...

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/misc Pull spi and regulator updates from Mark Brown: "At one point in the release cycle I managed to fat finger things and apply some SPI fixes onto a regulator branch and merge that into the SPI tree, then pull in a change shared with the MTD tree moving the Mediatek quadspi driver over to become the Mediatek spi-nor driver in the SPI tree. This has made a mess which I only just noticed while preparing this and I can't see a sensible way to unpick things due to other subsequent merge commits especially the pull from MTD so it looks like the most sensible thing to do is give up and combine the two pull requests. Fortunately both subsystems were fairly quiet this cycle, the highlights are: regulator: - Support for Monoloithic Power Systems MP5416, MP8867 and MPS8869 and Qualcomm PMI8994 and SMB208. SPI: - Lots of enhancements for spi-fsl-dspi, including XSPI mode support, from Vladimir Oltean. - Support for amlogic Meson G12A, IBM FSI, Mediatek spi-nor (moved from MTD), NXP i.MX8Mx, Rockchip PX30, RK3308 and RK3328, and Qualcomm Atheros AR934x/QCA95xx" * tag 'regulator-spi-v5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/misc: (118 commits) spi: efm32: Convert to use GPIO descriptors regulator: qcom_smd: Add pmi8994 regulator support regulator: da9063: Fix get_mode() functions to read sleep field spi: spi-fsl-lpspi: Replace zero-length array with flexible-array member spi: spi-s3c24xx: Replace zero-length array with flexible-array member spi: stm32: Fix comments compilation warnings spi: atmel-quadspi: Add verbose debug facilities to monitor register accesses spi: spi-fsl-dspi: Add support for LS1028A spi: spi-fsl-dspi: Move invariant configs out of dspi_transfer_one_message spi: spi-fsl-dspi: Fix interrupt-less DMA mode taking an XSPI code path spi: spi-fsl-dspi: Avoid NULL pointer in dspi_slave_abort for non-DMA mode spi: spi-fsl-dspi: Replace interruptible wait queue with a simple completion spi: spi-fsl-dspi: Protect against races on dspi->words_in_flight spi: spi-fsl-dspi: Avoid reading more data than written in EOQ mode spi: spi-fsl-dspi: Fix bits-per-word acceleration in DMA mode spi: spi-fsl-dspi: Fix little endian access to PUSHR CMD and TXDATA spi: spi-fsl-dspi: Don't access reserved fields in SPI_MCR regulator: driver.h: fix regulator_map_* function names regulator: da9063: fix suspend spi: mxs: Drop GPIO includes ...
