2021-12-12usb: core: config: fix validation of wMaxPacketValue entriesPavel Hofman1-1/+1
The checks performed by commit aed9d65ac327 ("USB: validate wMaxPacketValue entries in endpoint descriptors") require that initial value of the maxp variable contains both maximum packet size bits (10..0) and multiple-transactions bits (12..11). However, the existing code assings only the maximum packet size bits. This patch assigns all bits of wMaxPacketSize to the variable.

2021-12-11perf intel-pt: Fix state setting when receiving overflow (OVF) packetAdrian Hunter1-4/+28
An overflow (OVF packet) is treated as an error because it represents a loss of trace data, but there is no loss of synchronization, so the packet state should be INTEL_PT_STATE_IN_SYNC not INTEL_PT_STATE_ERR_RESYNC. To support that, some additional variables must be reset, and the FUP packet that may follow OVF is treated as an FUP event.

When syncing, it may be that branch packet generation is not enabled at that point, in which case there will not immediately be a control-flow packet, so some packets before a control flow packet turns up, get ignored.

2021-12-11perf tools: Prevent out-of-bounds access to registersGerman Gomez2-1/+7
The size of the cache of register values is arch-dependant (PERF_REGS_MAX). This has the potential of causing an out-of-bounds access in the function "perf_reg_value" if the local architecture contains less registers than the one the perf.data file was recorded on. Since the maximum number of registers is bound by the bitmask "u64 cache_mask", and the size of the cache when running under x86 systems is 64 already, fix the size to 64 and add a range-check to the function "perf_reg_value" to prevent out-of-bounds access.

2021-12-11mm: bdi: initialize bdi_min_ratio when bdi is unregisteredManjong Lee1-0/+7
Initialize min_ratio if it is set during bdi unregistration. This can prevent problems that may occur a when bdi is removed without resetting min_ratio. For example. 1) insert external sdcard 2) set external sdcard's min_ratio 70 3) remove external sdcard without setting min_ratio 0 4) insert external sdcard 5) set external sdcard's min_ratio 70 << error occur(can't set) Because when an sdcard is removed, the present bdi_min_ratio value will remain. Currently, the only way to reset bdi_min_ratio is to reboot.

2021-12-11mm/slub: fix endianness bug for alloc/free_traces attributesGerald Schaefer1-6/+9
On big-endian s390, the alloc/free_traces attributes produce endless output, because of always 0 idx in slab_debugfs_show(). idx is de-referenced from *v, which points to a loff_t value, with unsigned int idx = *(unsigned int *)v; This will only give the upper 32 bits on big-endian, which remain 0. Instead of only fixing this de-reference, during discussion it seemed more appropriate to change the seq_ops so that they use an explicit iterator in private loc_track struct. This patch adds idx to loc_track, which will also fix the endianness bug.

Currently, the single test program, debugfs.sh, contains all test cases for DAMON. When one of the cases fails, finding which case is failed from the test log is not so easy, and all remaining tests will be skipped. To improve the situation, this commit splits the single program into small test programs having their own names.
