2021-12-29ARM: 9160/1: NOMMU: Reload __secondary_data after PROCINFO_INITFUNCVladimir Murzin
[ Upstream commit 7202216a6f34d571a22274e729f841256bf8b1ef ] __secondary_data used to reside in r7 around call to PROCINFO_INITFUNC. After commit 95731b8ee63e ("ARM: 9059/1: cache-v7: get rid of mini-stack") r7 is used as a scratch register, so we have to reload __secondary_data before we setup the stack pointer.

commit 737e65c7956795b3553781fb7bc82fce1c39503f upstream. According to the i.MX6ULL Reference Manual, pad CSI_DATA07 may have the ESAI_TX0 functionality, not ESAI_T0. Also, NXP's i.MX Config Tools 10.0 generates dtsi with the MX6ULL_PAD_CSI_DATA07__ESAI_TX0 naming, so fix it accordingly. There are no devicetree users in mainline that use the old name, so just remove the old entry.

2021-11-25kmap_local: don't assume kmap PTEs are linear arrays in memoryArd Biesheuvel
commit 825c43f50e3aa811a291ffcb40e02fbf6d91ba86 upstream. The kmap_local conversion broke the ARM architecture, because the new code assumes that all PTEs used for creating kmaps form a linear array in memory, and uses array indexing to look up the kmap PTE belonging to a certain kmap index. On ARM, this cannot work, not only because the PTE pages may be non-adjacent in memory, but also because ARM/!LPAE interleaves hardware entries and extended entries (carrying software-only bits) in a way that is not compatible with array indexing. Fortunately, this only seems to affect configurations with more than 8 CPUs, due to the way the per-CPU kmap slots are organized in memory. Work around this by permitting an architecture to set a Kconfig symbol that signifies that the kmap PTEs do not form a lineary array in memory, and so the only way to locate the appropriate one is to walk the page tables.

2021-11-18ARM: 9156/1: drop cc-option fallbacks for architecture selectionArnd Bergmann
commit 418ace9992a7647c446ed3186df40cf165b67298 upstream. Naresh and Antonio ran into a build failure with latest Debian armhf compilers, with lots of output like tmp/ccY3nOAs.s:2215: Error: selected processor does not support `cpsid i' in ARM mode As it turns out, $(cc-option) fails early here when the FPU is not selected before CPU architecture is selected, as the compiler option check runs before enabling -msoft-float, which causes a problem when testing a target architecture level without an FPU: cc1: error: '-mfloat-abi=hard': selected architecture lacks an FPU Passing e.g. -march=armv6k+fp in place of -march=armv6k would avoid this issue, but the fallback logic is already broken because all supported compilers (gcc-5 and higher) are much more recent than these options, and building with -march=armv5t as a fallback no longer works. The best way forward that I see is to just remove all the checks, which also has the nice side-effect of slightly improving the startup time for 'make'. The -mtune=marvell-f option was apparently never supported by any mainline compiler, and the custom Codesourcery gcc build that did support is now too old to build kernels, so just use -mtune=xscale unconditionally for those. This should be safe to apply on all stable kernels, and will be required in order to keep building them with gcc-11 and higher.

[ Upstream commit 2012579b31293d0a8cf2024e9dab66810bf1a15e ] The SPI NOR is a bit further away from the SoC on DHCOR than on DHCOM, which causes additional signal delay. At 108 MHz, this delay triggers a sporadic issue where the first bit of RX data is not received by the QSPI controller. There are two options of addressing this problem, either by using the DLYB block to compensate the extra delay, or by reducing the QSPI bus clock frequency.

[ Upstream commit b3ea5d56f212ad81328c82454829a736197ebccc ] Currently the stacktrace on clang compiled arm kernel uses the 'lr' register to find the first frame address from pt_regs. However, that is wrong after calling another function, because the 'lr' register is used by 'bl' instruction and never be recovered. As same as gcc arm kernel, directly use the frame pointer (r11) of the pt_regs to find the first frame address. Note that this fixes kretprobe stacktrace issue only with CONFIG_UNWINDER_FRAME_POINTER=y. For the CONFIG_UNWINDER_ARM, we need another fix.

2021-10-19ARM: 9132/1: Fix __get_user_check failure with ARM KASAN imagesLexi Shao
ARM: kasan: Fix __get_user_check failure with kasan In macro __get_user_check defined in arch/arm/include/asm/uaccess.h, error code is store in register int __e(r0). When kasan is enabled, assigning value to kernel address might trigger kasan check, which unexpectedly overwrites r0 and causes undefined behavior on arm kasan images. One example is failure in do_futex and results in process soft lockup. Log: watchdog: BUG: soft lockup - CPU#0 stuck for 62946ms! [rs:main Q:Reg:1151] ... (__asan_store4) from (futex_wait_setup+0xf8/0x2b4) (futex_wait_setup) from (futex_wait+0x138/0x394) (futex_wait) from (do_futex+0x164/0xe40) (do_futex) from (sys_futex_time32+0x178/0x230) (sys_futex_time32) from (ret_fast_syscall+0x0/0x50) The soft lockup happens in function futex_wait_setup. The reason is function get_futex_value_locked always return EINVAL, thus pc jump back to retry label and causes looping. This line in function get_futex_value_locked ret = __get_user(*dest, from); is expanded to *dest = (typeof(*(p))) __r2; , in macro __get_user_check. Writing to pointer dest triggers kasan check and overwrites the return value of __get_user_x function. The assembly code of get_futex_value_locked in kernel/futex.c: ... c01f6dc8: eb0b020e bl c04b7608 <__get_user_4> // "x = (typeof(*(p))) __r2;" triggers kasan check and r0 is overwritten c01f6dCc: e1a00007 mov r0, r7 c01f6dd0: e1a05002 mov r5, r2 c01f6dd4: eb04f1e6 bl c0333574 <__asan_store4> c01f6dd8: e5875000 str r5, [r7] // save ret value of __get_user(*dest, from), which is dest address now c01f6ddc: e1a05000 mov r5, r0 ... // checking return value of __get_user failed c01f6e00: e3550000 cmp r5, #0 ... c01f6e0c: 01a00005 moveq r0, r5 // assign return value to EINVAL c01f6e10: 13e0000d mvnne r0, #13 Return value is the destination address of get_user thus certainly non-zero, so get_futex_value_locked always return EINVAL. Fix it by using a tmp vairable to store the error code before the assignment. This fix has no effects to non-kasan images thanks to compiler optimization. It only affects cases that overwrite r0 due to kasan check.

The noisy DSA driver (embedded switches) changes, and adjustment to IPv6 IOAM behavior add to diffstat's bottom line but are not scary.
