2021-07-21cacheinfo: clear cache_leaves(cpu) in free_cache_attributes()Xiongfeng Wang1-0/+1
On ARM64, when PPTT(Processor Properties Topology Table) is not implemented in ACPI boot, we will goto 'free_ci' with the following print: Unable to detect cache hierarchy for CPU 0 But some other codes may still use 'num_leaves' to iterate through the 'info_list', such as get_cpu_cacheinfo_id(). If 'info_list' is NULL , it would crash. So clear 'num_leaves' in free_cache_attributes().

2021-07-21firmware: fix theoretical UAF race with firmware cache and resumeZhen Lei1-12/+8
This race was discovered when I carefully analyzed the code to locate another firmware-related UAF issue. It can be triggered only when the firmware load operation is executed during suspend. This possibility is almost impossible because there are few firmware load and suspend actions in the actual environment. CPU0 CPU1 __device_uncache_fw_images(): assign_fw(): fw_cache_piggyback_on_request() <----- P0 spin_lock(&fwc->name_lock); ... list_del(&fce->list); spin_unlock(&fwc->name_lock); uncache_firmware(fce->name); <----- P1 kref_get(&fw_priv->ref); If CPU1 is interrupted at position P0, the new 'fce' has been added to the list fwc->fw_names by the fw_cache_piggyback_on_request(). In this case, CPU0 executes __device_uncache_fw_images() and will be able to see it when it traverses list fwc->fw_names. Before CPU1 executes kref_get() at P1, if CPU0 further executes uncache_firmware(), the count of fw_priv->ref may decrease to 0, causing fw_priv to be released in advance. Move kref_get() to the lock protection range of fwc->name_lock to fix it.

2021-07-21bus: Make remove callback return voidUwe Kleine-König86-243/+93
The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

This can be found in build log for first clean build which shows WARNING: EXPORT symbol "XXXX" [drivers/XXX/XXX.ko] version generation failed, symbol will not be versioned.

2021-07-18perf probe: Fix add event failure when running 32-bit perf in a 64-bit kernelYang Jihong6-42/+38
The "address" member of "struct probe_trace_point" uses long data type. If kernel is 64-bit and perf program is 32-bit, size of "address" variable is 32 bits.

2021-07-17Revert "mm/slub: use stackdepot to save stack trace in objects"Linus Torvalds2-50/+30
This reverts commit 788691464c29455346dc613a3b43c2fb9e5757a4. It's not clear why, but it causes unexplained problems in entirely unrelated xfs code. The most likely explanation is some slab corruption, possibly triggered due to CONFIG_SLUB_DEBUG_ON. See [1]. It ends up having a few other problems too, like build errors on arch/arc, and Geert reporting it using much more memory on m68k [3] (it probably does so elsewhere too, but it is probably just more noticeable on m68k). The architecture issues (both build and memory use) are likely just because this change effectively force-enabled STACKDEPOT (along with a very bad default value for the stackdepot hash size). But together with the xfs issue, this all smells like "this commit was not ready" to me.
