bpf: Add selftests to cover packet access corner cases

2021-12-14T13:49:06Z

commit b560b21f71eb4ef9dfc7c8ec1d0e4d7f9aa54b51 upstream. This commit adds BPF verifier selftests that cover all corner cases by packet boundary checks. Specifically, 8-byte packet reads are tested at the beginning of data and at the beginning of data_meta, using all kinds of boundary checks (all comparison operators: <, >, <=, >=; both permutations of operands: data + length compared to end, end compared to data + length). For each case there are three tests: 1. Length is just enough for an 8-byte read. Length is either 7 or 8, depending on the comparison. 2. Length is increased by 1 - should still pass the verifier. These cases are useful, because they failed before commit 2fa7d94afc1a ("bpf: Fix the off-by-two error in range markings"). 3. Length is decreased by 1 - should be rejected by the verifier. Some existing tests are just renamed to avoid duplication.

misc: fastrpc: fix improper packet size calculation

2021-12-14T13:49:06Z

commit 3a1bf591e9a410f220b7405a142a47407394a1d5 upstream. The buffer list is sorted and this is not being considered while calculating packet size. This would lead to improper copy length calculation for non-dmaheap buffers which would eventually cause sending improper buffers to DSP.

irqchip/irq-gic-v3-its.c: Force synchronisation when issuing INVALL

2021-12-14T13:49:06Z

commit b383a42ca523ce54bcbd63f7c8f3cf974abc9b9a upstream. INVALL CMD specifies that the ITS must ensure any caching associated with the interrupt collection defined by ICID is consistent with the LPI configuration tables held in memory for all Redistributors. SYNC is required to ensure that INVALL is executed. Currently, LPI configuration data may be inconsistent with that in the memory within a short period of time after the INVALL command is executed.

irqchip/armada-370-xp: Fix support for Multi-MSI interrupts

2021-12-14T13:49:06Z

commit d0a553502efd545c1ce3fd08fc4d423f8e4ac3d6 upstream. irq-armada-370-xp driver already sets MSI_FLAG_MULTI_PCI_MSI flag into msi_domain_info structure. But allocated interrupt numbers for Multi-MSI needs to be properly aligned otherwise devices send MSI interrupt with wrong number. Fix this issue by using function bitmap_find_free_region() instead of bitmap_find_next_zero_area() to allocate aligned interrupt numbers.

iio: ad7768-1: Call iio_trigger_notify_done() on error

2021-12-14T13:49:06Z

commit 6661146427cbbce6d1fe3dbb11ff1c487f55799a upstream. IIO trigger handlers must call iio_trigger_notify_done() when done. This must be done even when an error occurred. Otherwise the trigger will be seen as busy indefinitely and the trigger handler will never be called again. The ad7768-1 driver neglects to call iio_trigger_notify_done() when there is an error reading the converter data. Fix this by making sure that iio_trigger_notify_done() is included in the error exit path.

iio: adc: axp20x_adc: fix charging current reporting on AXP22x

2021-12-14T13:49:05Z

commit 92beafb76a31bdc02649eb44e93a8e4f4cfcdbe8 upstream. Both the charging and discharging currents on AXP22x are stored as 12-bit integers, in accordance with the datasheet. It's also confirmed by vendor BSP (axp20x_adc.c:axp22_icharge_to_mA). The scale factor of 0.5 is never mentioned in datasheet, nor in the vendor source code. I think it was here to compensate for erroneous addition bit in register width. Tested on custom A40i+AXP221s board with external ammeter as a reference.
