       "A last minute fix for a regression introduced in the v6.5 merge
        window.
      
        The conversion of the software based interrupt resend mechanism to
        hlist missed to add a check whether the descriptor is already enqueued
        and dropped the interrupt descriptor lookup for nested interrupts.
      
        The missing check whether the descriptor is already queued causes
        hlist corruption and can be observed in the wild. The dropped parent
        descriptor lookup has not yet caused problems, but it would result in
        stale interrupt line in the worst case.
      
        Add the missing enqueued check and bring the descriptor lookup back to
        cure this"

      genirq: Fix software resend lockup and nested resend · 9f5deb55
      Johan Hovold authored
      The switch to using hlist for managing software resend of interrupts
      broke resend in at least two ways:
      
      First, unconditionally adding interrupt descriptors to the resend list can
      corrupt the list when the descriptor in question has already been
      added. This causes the resend tasklet to loop indefinitely with interrupts
      disabled as was recently reported with the Lenovo ThinkPad X13s after
      threaded NAPI was disabled in the ath11k WiFi driver.
      
      This bug is easily fixed by restoring the old semantics of irq_sw_resend()
      so that it can be called also for descriptors that have already been marked
      for resend.
      
      Second, the offending commit also broke software resend of nested
      interrupts by simply discarding the code that made sure that such
      interrupts are retriggered using the parent interrupt.
      
      Add back the corresponding code that adds the parent descriptor to the
      resend list.
      
      Fixes: bc06a9e0 ("genirq: Use hlist for managing resend handlers")

      LoongArch: Ensure FP/SIMD registers in the core dump file is up to date · 656f9aec
      Huacai Chen authored
      This is a port of commit 379eb01c ("riscv: Ensure the value
      of FP registers in the core dump file is up to date").
      
      The values of FP/SIMD registers in the core dump file come from the
      thread.fpu. However, kernel saves the FP/SIMD registers only before
      scheduling out the process. If no process switch happens during the
      exception handling, kernel will not have a chance to save the latest
      values of FP/SIMD registers. So it may cause their values in the core
      dump file incorrect. To solve this problem, force fpr_get()/simd_get()
      to save the FP/SIMD registers into the thread.fpu if the target task
      equals the current task.

      lib/clz_ctz.c: Fix __clzdi2() and __ctzdi2() for 32-bit kernels · 382d4cd1
      Helge Deller authored
      The gcc compiler translates on some architectures the 64-bit
      __builtin_clzll() function to a call to the libgcc function __clzdi2(),
      which should take a 64-bit parameter on 32- and 64-bit platforms.
      
      But in the current kernel code, the built-in __clzdi2() function is
      defined to operate (wrongly) on 32-bit parameters if BITS_PER_LONG ==
      32, thus the return values on 32-bit kernels are in the range from
      [0..31] instead of the expected [0..63] range.
      
      This patch fixes the in-kernel functions __clzdi2() and __ctzdi2() to
      take a 64-bit parameter on 32-bit kernels as well, thus it makes the
      functions identical for 32- and 64-bit kernels.
      
      This bug went unnoticed since kernel 3.11 for over 10 years, and here
      are some possible reasons for that:
      
       a) Some architectures have assembly instructions to count the bits and
          which are used instead of calling __clzdi2(), e.g. on x86 the bsr
          instruction and on ppc cntlz is used. On such architectures the
          wrong __clzdi2() implementation isn't used and as such the bug has
          no effect and won't be noticed.
      
       b) Some architectures link to libgcc.a, and the in-kernel weak
          functions get replaced by the correct 64-bit variants from libgcc.a.
      
       c) __builtin_clzll() and __clzdi2() doesn't seem to be used in many
          places in the kernel, and most likely only in uncritical functions,
          e.g. when printing hex values via seq_put_hex_ll(). The wrong return
          value will still print the correct number, but just in a wrong
          formatting (e.g. with too many leading zeroes).
      
       d) 32-bit kernels aren't used that much any longer, so they are less
          tested.
      
      A trivial testcase to verify if the currently running 32-bit kernel is
      affected by the bug is to look at the output of /proc/self/maps:
      
      Here the kernel uses a correct implementation of __clzdi2():
      
        root@debian:~# cat /proc/self/maps
        00010000-00019000 r-xp 00000000 08:05 787324     /usr/bin/cat
        00019000-0001a000 rwxp 00009000 08:05 787324     /usr/bin/cat
        0001a000-0003b000 rwxp 00000000 00:00 0          [heap]

        ...
      
      and this kernel uses the broken implementation of __clzdi2():
      
        root@debian:~# cat /proc/self/maps
        0000000010000-0000000019000 r-xp 00000000 000000008:000000005 787324  /usr/bin/cat

       "This is obviously not ideal, particularly for something this late in
        the cycle.
      
        Unfortunately we found some uABI issues in the vector support while
        reviewing the GDB port, which has triggered a revert -- probably a
        good sign we should have reviewed GDB before merging this, I guess I
        just dropped the ball because I was so worried about the context
        extension and libc suff I forgot. Hence the late revert.
      
        There's some risk here as we're still exposing the vector context for
        signal handlers, but changing that would have meant reverting all of
        the vector support. The issues we've found so far have been fixed
        already and they weren't absolute showstoppers, so we're essentially
        just playing it safe by holding ptrace support for another release (or
        until we get through a proper userspace code review).

      LoongArch: Put the body of play_dead() into arch_cpu_idle_dead() · c337c849
      Tiezhu Yang authored
      The initial aim is to silence the following objtool warning:
      
      arch/loongarch/kernel/process.o: warning: objtool: arch_cpu_idle_dead() falls through to next function start_thread()
      
      According to tools/objtool/Documentation/objtool.txt, this is because
      the last instruction of arch_cpu_idle_dead() is a call to a noreturn
      function play_dead(). In order to silence the warning, one simple way
      is to add the noreturn function play_dead() to objtool's hard-coded
      global_noreturns array, that is to say, just put "NORETURN(play_dead)"
      into tools/objtool/noreturns.h, it works well.
      
      But I noticed that play_dead() is only defined once and only called by
      arch_cpu_idle_dead(), so put the body of play_dead() into the caller
      arch_cpu_idle_dead(), then remove the noreturn function play_dead() is
      an alternative way which can reduce the overhead of the function call
      at the same time.

      After the call to oops_exit(), it should not panic or execute
      the crash kernel if the oops is to be suppressed.

      LoongArch: Do not kill the task in die() if notify_die() returns NOTIFY_STOP · 6933c11f
      Tiezhu Yang authored
      If notify_die() returns NOTIFY_STOP, honor the return value from the
      handler chain invocation in die() and return without killing the task
      as, through a debugger, the fault may have been fixed. It makes sense
      even if ignoring the event will make the system unstable: by allowing
      access through a debugger it has been compromised already anyway. It
      makes our port consistent with x86, arm64, riscv and csky.
      
      Commit 20c0d2d4 ("[PATCH] i386: pass proper trap numbers to die
      chain handlers") may be the earliest of similar changes.

      LoongArch: Replace -ffreestanding with finer-grained -fno-builtin's · 3f301dc2
      WANG Xuerui authored
      As explained by Nick in the original issue: the kernel usually does a
      good job of providing library helpers that have similar semantics as
      their ordinary userspace libc equivalents, but -ffreestanding disables
      such libcall optimization and other related features in the compiler,
      which can lead to unexpected things such as CONFIG_FORTIFY_SOURCE not
      working (!).
      
      However, due to the desire for better control over unaligned accesses
      with respect to CONFIG_ARCH_STRICT_ALIGN, and also for avoiding the
      GCC bug https://gcc.gnu.org/PR109465, we do want to still disable
      optimizations for the memory libcalls (memcpy, memmove and memset for
      now). Use finer-grained -fno-builtin-* toggles to achieve this without
      losing source fortification and other libcall optimizations.

      Xi Ruoyao authored
      In drivers/Kconfig, drivers/firmware/Kconfig is sourced for all ports so
      there is no need to source it in the port-specific Kconfig file.  And
      sourcing it here also caused the "Firmware Drivers" menu appeared two
      times: one in the "Device Drivers" menu, another in the toplevel menu.
      This is really puzzling so remove it.

      Pull tracing fixes from Steven Rostedt:
      
       - Fix ring buffer being permanently disabled due to missed
         record_disabled()
      
         Changing the trace cpu mask will disable the ring buffers for the
         CPUs no longer in the mask. But it fails to update the snapshot
         buffer. If a snapshot takes place, the accounting for the ring buffer
         being disabled is corrupted and this can lead to the ring buffer
         being permanently disabled.
      
       - Add test case for snapshot and cpu mask working together
      
       - Fix memleak by the function graph tracer not getting closed properly.
      
         The iterator is used to read the ring buffer. When it opens, it calls
         the open function of a tracer, and when it is closed, it calls the
         close iteration. While a trace is being read, it is still possible to
         change the tracer.
      
         If this happens between the function graph tracer and the wakeup
         tracer (which uses function graph tracing), the tracers are not
         closed properly during when the iterator sees the switch, and the
         wakeup function did not initialize its private pointer to NULL, which
         is used to know if the function graph tracer was the last tracer. It
         could be fooled in thinking it is, but then on exit it does not call
         the close function of the function graph tracer to clean up its data.
      
       - Fix synthetic events on big endian machines, by introducing a union
         that does the conversions properly.
      
       - Fix synthetic events from printing out the number of elements in the
         stacktrace when it shouldn't.
      
       - Fix synthetic events stacktrace to not print a bogus value at the
         end.
      
       - Introduce a pipe_cpumask that prevents the trace_pipe files from
         being opened by more than one task (file descriptor).
      
         There was a race found where if splice is called, the iter->ent could
         become stale and events could be missed. There's no point reading a
         producer/consumer file by more than one task as they will corrupt
         each other anyway. Add a cpumask that keeps track of the per_cpu
         trace_pipe files as well as the global trace_pipe file that prevents
         more than one open of a trace_pipe file that represents the same ring
         buffer. This prevents the race from happening.
      
       - Fix ftrace samples for arm64 to work with older compilers.

      to avoid double free of 'tgt' and move put_device(&tgt->dev) after the
      removed kfree(tgt) to avoid a use-after-free.
