2023-03-09tracing: Check field value in hist_field_name()Steven Rostedt (Google)
The function hist_field_name() cannot handle being passed a NULL field parameter. It should never be NULL, but due to a previous bug, NULL was passed to the function and the kernel crashed due to a NULL dereference. Mark Rutland reported this to me on IRC. The bug was fixed, but to prevent future bugs from crashing the kernel, check the field and add a WARN_ON() if it is NULL.

Some storage, such as AIX VDASD (virtual storage) and IBM 2076 (front end), fail as a result of commit c92a6b5d6335 ("scsi: core: Query VPD size before getting full page"). That commit changed getting SCSI VPD pages so that we now read just enough of the page to get the actual page size, then read the whole page in a second read. The problem is that the above mentioned hardware returns zero for the page size, because of a firmware error. In such cases, until the firmware is fixed, this new blacklist flag says to revert to the original method of reading the VPD pages, i.e. try to read a whole buffer's worth on the first try.

2023-03-09Merge patch series "riscv: asid: switch to alternative way to fix stale TLB ↵Palmer Dabbelt
entries" Sergey Matyukevich <geomatsi@gmail.com> says: Some time ago two different patches have been posted to fix stale TLB entries that caused applications crashes. The patch [0] suggested 'aggregating' mm_cpumask, i.e. current cpu is not cleared for the switched-out task in switch_mm function. For additional explanations see the commit message by Guo Ren. The same approach is used by arc architecture, so another good comment is for switch_mm in arch/arc/include/asm/mmu_context.h. The patch [1] attempted to reduce the number of TLB flushes by deferring (and possibly avoiding) them for CPUs not running the task. Patch [1] has been merged. However we already have two bug reports from different vendors. So apparently something is missing in the approach suggested in [1]. In both cases the patch [0] fixed the issue. This patch series reverts [1] and replaces it by [0].

2023-03-09riscv: asid: Fixup stale TLB entry cause application crashGuo Ren
After use_asid_allocator is enabled, the userspace application will crash by stale TLB entries. Because only using cpumask_clear_cpu without local_flush_tlb_all couldn't guarantee CPU's TLB entries were fresh. Then set_mm_asid would cause the user space application to get a stale value by stale TLB entry, but set_mm_noasid is okay. Here is the symptom of the bug: unhandled signal 11 code 0x1 (coredump) 0x0000003fd6d22524 <+4>: auipc s0,0x70 0x0000003fd6d22528 <+8>: ld s0,-148(s0) # 0x3fd6d92490 => 0x0000003fd6d2252c <+12>: ld a5,0(s0) (gdb) i r s0 s0 0x8082ed1cc3198b21 0x8082ed1cc3198b21 (gdb) x /2x 0x3fd6d92490 0x3fd6d92490: 0xd80ac8a8 0x0000003f The core dump file shows that register s0 is wrong, but the value in memory is correct. Because 'ld s0, -148(s0)' used a stale mapping entry in TLB and got a wrong result from an incorrect physical address. When the task ran on CPU0, which loaded/speculative-loaded the value of address(0x3fd6d92490), then the first version of the mapping entry was PTWed into CPU0's TLB. When the task switched from CPU0 to CPU1 (No local_tlb_flush_all here by asid), it happened to write a value on the address (0x3fd6d92490). It caused do_page_fault -> wp_page_copy -> ptep_clear_flush -> ptep_get_and_clear & flush_tlb_page. The flush_tlb_page used mm_cpumask(mm) to determine which CPUs need TLB flush, but CPU0 had cleared the CPU0's mm_cpumask in the previous switch_mm. So we only flushed the CPU1 TLB and set the second version mapping of the PTE. When the task switched from CPU1 to CPU0 again, CPU0 still used a stale TLB mapping entry which contained a wrong target physical address. It raised a bug when the task happened to read that value. CPU0 CPU1 - switch 'task' in - read addr (Fill stale mapping entry into TLB) - switch 'task' out (no tlb_flush) - switch 'task' in (no tlb_flush) - write addr cause pagefault do_page_fault() (change to new addr mapping) wp_page_copy() ptep_clear_flush() ptep_get_and_clear() & flush_tlb_page() write new value into addr - switch 'task' out (no tlb_flush) - switch 'task' in (no tlb_flush) - read addr again (Use stale mapping entry in TLB) get wrong value from old phyical addr, BUG! The solution is to keep all CPUs' footmarks of cpumask(mm) in switch_mm, which could guarantee to invalidate all stale TLB entries during TLB flush.

We're currently using stop_machine() to update ftrace & kprobes, which means that the thread that takes text_mutex during may not be the same as the thread that eventually patches the code. This isn't actually a race because the lock is still held (preventing any other concurrent accesses) and there is only one thread running during stop_machine(), but it does trigger a lockdep failure. This patch just elides the lockdep check during stop_machine.

2023-03-09i2c: dev: Fix bus callback return valuesGeert Uytterhoeven
The i2cdev_{at,de}tach_adapter() callbacks are used for two purposes: 1. As notifier callbacks, when (un)registering I2C adapters created or destroyed after i2c_dev_init(), 2. As bus iterator callbacks, for registering already existing adapters from i2c_dev_init(), and for cleanup. Unfortunately both use cases expect different return values: the former expects NOTIFY_* return codes, while the latter expects zero or error codes, and aborts in case of error. Hence in case 2, as soon as i2cdev_{at,de}tach_adapter() returns (non-zero) NOTIFY_OK, the bus iterator aborts. This causes (a) only the first already existing adapter to be registered, leading to missing /dev/i2c-* entries, and (b) a failure to unregister all but the first I2C adapter during cleanup. Fix this by introducing separate callbacks for the bus iterator, wrapping the notifier functions, and always returning succes. Any errors inside these callback functions are unlikely to happen, and are fatal anyway.

2023-03-09arm64: dts: qcom: sc8280xp-x13s: fix va dmic dai links and routingSrinivas Kandagatla
VA dmics 0, 1, 2 micbias on X13s are connected to WCD MICBIAS1, WCD MICBIAS1 and WCD MICBIAS3 respectively. Reflect this in dt to get dmics working. Also fix dmics to go via VA Macro instead of TX macro to fix device switching.
