[ Upstream commit 40502074 ] The 258a:6a88 keyboard-dock shipped with the Prowise PT301 tablet is likely another ITE based design. The controller die is directly bonded to the PCB with a blob of black glue on top so there are no markings and the 258a vendor-id used is unknown anywhere. But the keyboard has the exact same hotkeys mapped to Fn+F1 - F10 as the other ITE8595 keyboard I have *and* it has the same quirky behavior wrt the rfkill hotkey. Either way as said this keyboard has the same quirk for its rfkill / airplane mode hotkey as the ITE 8595 chip, it only sends a single release event when pressed and released, it never sends a press event. This commit adds the 258a:6a88 USB id to the hid-ite id-table, fixing the rfkill key not working on this keyboard. Signed-off-by:

[ Upstream commit 5564597d ] Commit 6975a783 ("powerpc/boot: Allow building the zImage wrapper as a relocatable ET_DYN", 2011-04-12) changed the procedure descriptor at the start of crt0.S to have a hard-coded start address of 0x500000 rather than a reference to _zimage_start, presumably because having a reference to a symbol introduced a relocation which is awkward to handle in a position-independent executable. Unfortunately, what is at 0x500000 in the COFF image is not the first instruction, but the procedure descriptor itself, that is, a word containing 0x500000, which is not a valid instruction. Hence, booting a COFF zImage results in a "DEFAULT CATCH!, code=FFF00700" message from Open Firmware. This fixes the problem by (a) putting the procedure descriptor in the data section and (b) adding a branch to _zimage_start as the first instruction in the program.

commit 66a4059b upstream. MIPS' asm/mmzone.h includes the machine/platform mmzone.h unconditionally, but since commit bb53fdf3 ("MIPS: c-r4k: Add r4k_blast_scache_node for Loongson-3") is included by asm/rk4cache.h for all r4k-style configs regardless of CONFIG_NEED_MULTIPLE_NODES. This is problematic when CONFIG_NEED_MULTIPLE_NODES=n because both the loongson3 & ip27 mmzone.h headers unconditionally define the NODE_DATA preprocessor macro which is aready defined by linux/mmzone.h, resulting in the following build error: In file included from ./arch/mips/include/asm/mmzone.h:10, from ./arch/mips/include/asm/r4kcache.h:23, from arch/mips/mm/c-r4k.c:33: ./arch/mips/include/asm/mach-loongson64/mmzone.h:48: error: "NODE_DATA" redefined [-Werror] #define NODE_DATA(n) (&__node_data[(n)]->pglist) In file included from ./include/linux/topology.h:32, from ./include/linux/irq.h:19, from ./include/asm-generic/hardirq.h:13, from ./arch/mips/include/asm/hardirq.h:16, from ./include/linux/hardirq.h:9, from arch/mips/mm/c-r4k.c:11: ./include/linux/mmzone.h:907: note: this is the location of the previous definition #define NODE_DATA(nid) (&contig_page_data) Resolve this by only including the machine mmzone.h when CONFIG_NEED_MULTIPLE_NODES=y, which also removes the need for the empty mach-generic version of the header which we delete.

commit 169113ec upstream. The ARM Linux kernel handles the EABI syscall numbers as follows: 0 - NR_SYSCALLS-1 : Invoke syscall via syscall table NR_SYSCALLS - 0xeffff : -ENOSYS (to be allocated in future) 0xf0000 - 0xf07ff : Private syscall or -ENOSYS if not allocated > 0xf07ff : SIGILL Our compat code gets this wrong and ends up sending SIGILL in response to all syscalls greater than NR_SYSCALLS which have a value greater than 0x7ff in the bottom 16 bits. Fix this by defining the end of the ARM private syscall region and checking the syscall number against that directly. Update the comment while we're at it.

commit 3cd508a8 upstream. When we insert the sync sequence number into the CMD_SYNC.MSIData field, we do so in CPU-native byte order, before writing out the whole command as explicitly little-endian dwords. Thus on big-endian systems, the SMMU will receive and write back a byteswapped version of sync_nr, which would be perfect if it were targeting a similarly-little-endian ITS, but since it's actually writing back to memory being polled by the CPUs, they're going to end up seeing the wrong thing. Since the SMMU doesn't care what the MSIData actually contains, the minimal-overhead solution is to simply add an extra byteswap initially, such that it then writes back the big-endian format directly.

commit c23b2e6f upstream. When using the nospec API, it should be taken into account that: "...if the CPU speculates past the bounds check then * array_index_nospec() will clamp the index within the range of [0, * size)." The above is part of the header for macro array_index_nospec() in linux/nospec.h Now, in this particular case, if intid evaluates to exactly VGIC_MAX_SPI or to exaclty VGIC_MAX_PRIVATE, the array_index_nospec() macro ends up returning VGIC_MAX_SPI - 1 or VGIC_MAX_PRIVATE - 1 respectively, instead of VGIC_MAX_SPI or VGIC_MAX_PRIVATE, which, based on the original logic: /* SGIs and PPIs */ if (intid <= VGIC_MAX_PRIVATE) return &vcpu->arch.vgic_cpu.private_irqs[intid]; /* SPIs */ if (intid <= VGIC_MAX_SPI) return &kvm->arch.vgic.spis[intid - VGIC_NR_PRIVATE_IRQS]; are valid values for intid. Fix this by calling array_index_nospec() macro with VGIC_MAX_PRIVATE + 1 and VGIC_MAX_SPI + 1 as arguments for its parameter size.

commit 2e2f6c3c upstream. To change the active state of an MMIO, halt is requested for all vcpus of the affected guest before modifying the IRQ state. This is done by calling cond_resched_lock() in vgic_mmio_change_active(). However interrupts are disabled at this point and we cannot reschedule a vcpu. We actually don't need any of this, as kvm_arm_halt_guest ensures that all the other vcpus are out of the guest. Let's just drop that useless code. Signed-off-by:

commit 8ac686d7 upstream. The assigned parent clocks should be normally specified in the consumer device's DT node, this ensures respective driver always sees correct clock settings when required. This patch fixes regression in audio subsystem on Odroid XU3/XU4 boards that appeared after commits: commit 647d04f8 ("ASoC: samsung: i2s: Ensure the RCLK rate is properly determined") commit 995e73e5 ("ASoC: samsung: i2s: Fix rclk_srcrate handling") commit 48279c53 ("ASoC: samsung: i2s: Prevent external abort on exynos5433 I2S1 access") Without this patch the driver gets wrong clock as the I2S function clock (op_clk) in probe() and effectively the clock which is finally assigned from DT is not being enabled/disabled in the runtime resume/suspend ops. Without the above listed commits the EXYNOS_I2S_BUS clock was always set as parent of CLK_I2S_RCLK_SRC regardless of DT settings so there was no issue with not enabled EXYNOS_SCLK_I2S.

commit 107352a2 upstream. We currently only halt the guest when a vCPU messes with the active state of an SPI.

commit df655b75 upstream.

commit 9a596f5b upstream. While resolving a bug with locks on samba shares found a strange behavior. When a file locked by one node and we trying to lock it from another node it fail with errno 5 (EIO) but in that case errno must be set to (EACCES | EAGAIN). This isn't happening when we try to lock file second time on same node. In this case it returns EACCES as expected. Also this issue not reproduces when we use SMB1 protocol (vers=1.0 in mount options). Further investigation showed that the mapping from status_to_posix_error is different for SMB1 and SMB2+ implementations. For SMB1 mapping is [NT_STATUS_LOCK_NOT_GRANTED to ERRlock] (See fs/cifs/netmisc.c line 66) but for SMB2+ mapping is [STATUS_LOCK_NOT_GRANTED to -EIO] (see fs/cifs/smb2maperror.c line 383) Quick changes in SMB2+ mapping from EIO to EACCES has fixed issue.

commit ff4dd232 upstream. ASIDs have always been stored as unsigned longs, ie. 32 bits on MIPS32 kernels. This is problematic because it is feasible for the ASID version to overflow & wrap around to zero. We currently attempt to handle this overflow by simply setting the ASID version to 1, using asid_first_version(), but we make no attempt to account for the fact that there may be mm_structs with stale ASIDs that have versions which we now reuse due to the overflow & wrap around. Encountering this requires that: 1) A struct mm_struct X is active on CPU A using ASID (V,n). 2) That mm is not used on CPU A for the length of time that it takes for CPU A's asid_cache to overflow & wrap around to the same version V that the mm had in step 1. During this time tasks using the mm could either be sleeping or only scheduled on other CPUs. 3) Some other mm Y becomes active on CPU A and is allocated the same ASID (V,n). 4) mm X now becomes active on CPU A again, and now incorrectly has the same ASID as mm Y. Where struct mm_struct ASIDs are represented above in the format (version, EntryHi.ASID), and on a typical MIPS32 system version will be 24 bits wide & EntryHi.ASID will be 8 bits wide. The length of time required in step 2 is highly dependent upon the CPU & workload, but for a hypothetical 2GHz CPU running a workload which generates a new ASID every 10000 cycles this period is around 248 days. Due to this long period of time & the fact that tasks need to be scheduled in just the right (or wrong, depending upon your inclination) way, this is obviously a difficult bug to encounter but it's entirely possible as evidenced by reports. In order to fix this, simply extend ASIDs to 64 bits even on MIPS32 builds. This will extend the period of time required for the hypothetical system above to encounter the problem from 28 days to around 3 trillion years, which feels safely outside of the realms of possibility. The cost of this is slightly more generated code in some commonly executed paths, but this is pretty minimal: | Code Size Gain | Percentage -----------------------|----------------|------------- decstation_defconfig | +270 | +0.00% 32r2el_defconfig | +652 | +0.01% 32r6el_defconfig | +1000 | +0.01% I have been unable to measure any change in performance of the LMbench lat_ctx or lat_proc tests resulting from the 64b ASIDs on either 32r2el_defconfig+interAptiv or 32r6el_defconfig+I6500 systems.

commit adcc81f1 upstream. Mapping the delay slot emulation page as both writeable & executable presents a security risk, in that if an exploit can write to & jump into the page then it can be used as an easy way to execute arbitrary code. Prevent this by mapping the page read-only for userland, and using access_process_vm() with the FOLL_FORCE flag to write to it from mips_dsemul(). This will likely be less efficient due to copy_to_user_page() performing cache maintenance on a whole page, rather than a single line as in the previous use of flush_cache_sigtramp(). However this delay slot emulation code ought not to be running in any performance critical paths anyway so this isn't really a problem, and we can probably do better in copy_to_user_page() anyway in future. A major advantage of this approach is that the fix is small & simple to backport to stable kernels. Reported-by:

commit f024cf08 upstream. In the case that a bprintk event has a dereferenced pointer that is stored as a string, and there's more values to process (more args), the arg was not updated to point to the next arg after processing the dereferenced pointer, and it screwed up what was to be displayed.

commit e5f71a27 upstream. text[s] is a signed char, so using that as index into the font8x16 array can result in negative indices. Cast it to u8 to be safe. Signed-off-by:

commit 62dcb4f4 upstream. vb2_core_create_bufs did not check if the memory model for newly added buffers is the same as for already existing buffers. It should return an error if they aren't the same. Signed-off-by:

commit cea8c007 upstream. imx274_read_reg() takes a u8 pointer ("reg") and casts it to pass it to regmap_read(), which takes an unsigned int pointer. This results in a corrupted stack and random crashes. Fixes: 0985dd30 ("media: imx274: V4l2 driver for Sony imx274 CMOS sensor") Cc: stable@vger.kernel.org # for 4.15 and up Signed-off-by:
