      treewide: Convert del_timer*() to timer_shutdown*() · 292a089d
      Steven Rostedt (Google) authored
      Due to several bugs caused by timers being re-armed after they are
      shutdown and just before they are freed, a new state of timers was added
      called "shutdown".  After a timer is set to this state, then it can no
      longer be re-armed.
      
      The following script was run to find all the trivial locations where
      del_timer() or del_timer_sync() is called in the same function that the
      object holding the timer is freed.  It also ignores any locations where
      the timer->function is modified between the del_timer*() and the free(),
      as that is not considered a "trivial" case.
      
      This was created by using a coccinelle script and the following
      commands:
      
          $ cat timer.cocci
          @@
          expression ptr, slab;
          identifier timer, rfield;
          @@
          (
          -       del_timer(&ptr->timer);
          +       timer_shutdown(&ptr->timer);
          |
          -       del_timer_sync(&ptr->timer);
          +       timer_shutdown_sync(&ptr->timer);
          )
            ... when strict
                when != ptr->timer
          (
                  kfree_rcu(ptr, rfield);
          |
                  kmem_cache_free(slab, ptr);
          |
                  kfree(ptr);
          )
      
          $ spatch timer.cocci . > /tmp/t.patch
          $ patch -p1 < /tmp/t.patch

      pstore: Properly assign mem_type property · beca3e31
      Luca Stefani authored
      If mem-type is specified in the device tree
      it would end up overriding the record_size
      field instead of populating mem_type.
      
      As record_size is currently parsed after the
      improper assignment with default size 0 it
      continued to work as expected regardless of the
      value found in the device tree.
      
      Simply changing the target field of the struct
      is enough to get mem-type working as expected.

      pstore: Make sure CONFIG_PSTORE_PMSG selects CONFIG_RT_MUTEXES · 2f4fec59
      John Stultz authored
      In commit 76d62f24 ("pstore: Switch pmsg_lock to an rt_mutex
      to avoid priority inversion") I changed a lock to an rt_mutex.
      
      However, its possible that CONFIG_RT_MUTEXES is not enabled,
      which then results in a build failure, as the 0day bot detected:
        https://lore.kernel.org/linux-mm/202212211244.TwzWZD3H-lkp@intel.com/
      
      Thus this patch changes CONFIG_PSTORE_PMSG to select
      CONFIG_RT_MUTEXES, which ensures the build will not fail.

      cfi: Fix CFI failure with KASAN · cf801640
      Sami Tolvanen authored
      When CFI_CLANG and KASAN are both enabled, LLVM doesn't generate a
      CFI type hash for asan.module_ctor functions in translation units
      where CFI is disabled, which leads to a CFI failure during boot when
      do_ctors calls the affected constructors:
      
        CFI failure at do_basic_setup+0x64/0x90 (target:
        asan.module_ctor+0x0/0x28; expected type: 0xa540670c)
      
      Specifically, this happens because CFI is disabled for
      kernel/cfi.c. There's no reason to keep CFI disabled here anymore, so
      fix the failure by not filtering out CC_FLAGS_CFI for the file.
      
      Note that https://reviews.llvm.org/rG3b14862f0a96 fixed the issue
      where LLVM didn't emit CFI type hashes for any sanitizer constructors,
      but now type hashes are emitted correctly for TUs that use CFI.
