2021-09-17btrfs: replace BUG_ON() in btrfs_csum_one_bio() with proper error handlingQu Wenruo
There is a BUG_ON() in btrfs_csum_one_bio() to catch code logic error. It has indeed caught several bugs during subpage development. But the BUG_ON() itself will bring down the whole system which is an overkill. Replace it with a WARN() and exit gracefully, so that it won't crash the whole system while we can still catch the code logic error.

Pull io_uring iov_iter retry fixes from Jens Axboe: "This adds a helper to save/restore iov_iter state, and modifies io_uring to use it. After that is done, we can now kill the iter->truncated addition that we added for this release. The io_uring change is being overly cautious with the save/restore/advance, but better safe than sorry and we can always improve that and reduce the overhead if it proves to be of concern. The only case to be worried about in this regard is huge IO, where iteration can take a while to iterate segments. I spent some time writing test cases, and expanded the coverage quite a bit from the last posting of this. liburing carries this regression test case now: https://git.kernel.dk/cgit/liburing/tree/test/file-verify.c which exercises all of this. It now also supports provided buffers, and explicitly tests for end-of-file/device truncation as well. On top of that, Pavel sanitized the IOPOLL retry path to follow the exact same pattern as normal IO" * tag 'iov_iter.3-5.15-2021-09-17' of git://git.kernel.dk/linux-block: io_uring: move iopoll reissue into regular IO path Revert "iov_iter: track truncated size" io_uring: use iov_iter state save/restore helpers iov_iter: add helper to save iov_iter state

2021-09-17mm: Fully initialize invalidate_lock, amend lock class laterSebastian Andrzej Siewior
The function __init_rwsem() is not part of the official API, it just a helper function used by init_rwsem(). Changing the lock's class and name should be done by using lockdep_set_class_and_name() after the has been fully initialized. The overhead of the additional class struct and setting it twice is negligible and it works across all locks. Fully initialize the lock with init_rwsem() and then set the custom class and name for the lock.

2021-09-17pinctrl: qcom: spmi-gpio: correct parent irqspec translationDavid Collins
pmic_gpio_child_to_parent_hwirq() and gpiochip_populate_parent_fwspec_fourcell() translate a pinctrl- spmi-gpio irqspec to an SPMI controller irqspec. When they do this, they use a fixed SPMI slave ID of 0 and a fixed GPIO peripheral offset of 0xC0 (corresponding to SPMI address 0xC000). This translation results in an incorrect irqspec for secondary PMICs that don't have a slave ID of 0 as well as for PMIC chips which have GPIO peripherals located at a base address other than 0xC000. Correct this issue by passing the slave ID of the pinctrl-spmi- gpio device's parent in the SPMI controller irqspec and by calculating the peripheral ID base from the device tree 'reg' property of the pinctrl-spmi-gpio device.

2021-09-16hwmon: (mlxreg-fan) Return non-zero value when fan current state is enforced ↵Vadim Pasternak
from sysfs Fan speed minimum can be enforced from sysfs. For example, setting current fan speed to 20 is used to enforce fan speed to be at 100% speed, 19 - to be not below 90% speed, etcetera. This feature provides ability to limit fan speed according to some system wise considerations, like absence of some replaceable units or high system ambient temperature. Request for changing fan minimum speed is configuration request and can be set only through 'sysfs' write procedure. In this situation value of argument 'state' is above nominal fan speed maximum. Return non-zero code in this case to avoid thermal_cooling_device_stats_update() call, because in this case statistics update violates thermal statistics table range. The issues is observed in case kernel is configured with option CONFIG_THERMAL_STATISTICS. Here is the trace from KASAN: [ 159.506659] BUG: KASAN: slab-out-of-bounds in thermal_cooling_device_stats_update+0x7d/0xb0 [ 159.516016] Read of size 4 at addr ffff888116163840 by task hw-management.s/7444 [ 159.545625] Call Trace: [ 159.548366] dump_stack+0x92/0xc1 [ 159.552084] ? thermal_cooling_device_stats_update+0x7d/0xb0 [ 159.635869] thermal_zone_device_update+0x345/0x780 [ 159.688711] thermal_zone_device_set_mode+0x7d/0xc0 [ 159.694174] mlxsw_thermal_modules_init+0x48f/0x590 [mlxsw_core] [ 159.700972] ? mlxsw_thermal_set_cur_state+0x5a0/0x5a0 [mlxsw_core] [ 159.731827] mlxsw_thermal_init+0x763/0x880 [mlxsw_core] [ 160.070233] RIP: 0033:0x7fd995909970 [ 160.074239] Code: 73 01 c3 48 8b 0d 28 d5 2b 00 f7 d8 64 89 01 48 83 c8 ff c3 66 0f 1f 44 00 00 83 3d 99 2d 2c 00 00 75 10 b8 01 00 00 00 0f 05 <48> 3d 01 f0 ff ..

2021-09-16net: 6pack: Fix tx timeout and slot timeGuenter Roeck
tx timeout and slot time are currently specified in units of HZ. On Alpha, HZ is defined as 1024. When building alpha:allmodconfig, this results in the following error message. drivers/net/hamradio/6pack.c: In function 'sixpack_open': drivers/net/hamradio/6pack.c:71:41: error: unsigned conversion from 'int' to 'unsigned char' changes value from '256' to '0' In the 6PACK protocol, tx timeout is specified in units of 10 ms and transmitted over the wire: https://www.linux-ax25.org/wiki/6PACK Defining a value dependent on HZ doesn't really make sense, and presumably comes from the (very historical) situation where HZ was originally 100. Note that the SIXP_SLOTTIME use explicitly is about 10ms granularity: mod_timer(&sp->tx_t, jiffies + ((when + 1) * HZ) / 100); and the SIXP_TXDELAY walue is sent as a byte over the wire.

2021-09-163com 3c515: make it compile on 64-bit architecturesLinus Torvalds
This driver isn't enabled most places because of the ISA config dependency, but alpha still has it. And I think the 'Jensen' actually did have an ISA slot. However, it doesn't build cleanly, because the "Vortex bus master" code just casts the skb->data pointer to 'int': outl((int) (skb->data), ioaddr + Wn7_MasterAddr); which is all kinds of broken. Even on a good old traditional PC/AT it would be broken because the high bits will be random kernel address bits, but presumably the hardware ignores those bits. I mean, it's ISA. We're talking 16MB dma limits. The "good old days". Make the build happy with this kind of craziness by using the proper isa_virt_to_bus() handling that the full bus master code uses anyway (the Vortex bus mastering is a limited special case). Who knows, this might even work. Reported-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2021-09-16arm64/sve: Use correct size when reinitialising SVE stateMark Brown
When we need a buffer for SVE register state we call sve_alloc() to make sure that one is there. In order to avoid repeated allocations and frees we keep the buffer around unless we change vector length and just memset() it to ensure a clean register state. The function that deals with this takes the task to operate on as an argument, however in the case where we do a memset() we initialise using the SVE state size for the current task rather than the task passed as an argument. This is only an issue in the case where we are setting the register state for a task via ptrace and the task being configured has a different vector length to the task tracing it. In the case where the buffer is larger in the traced process we will leak old state from the traced process to itself, in the case where the buffer is smaller in the traced process we will overflow the buffer and corrupt memory.
