      net/scm: Fix typo in SCM_RIGHTS compat refactoring · 16b89f69
      Kees Cook authored
      When refactoring the SCM_RIGHTS code, I accidentally mis-merged my
      native/compat diffs, which entirely broke using SCM_RIGHTS in compat
      mode. Use the correct helper.

      Pull powerpc updates from Michael Ellerman:
      
       - Add support for (optionally) using queued spinlocks & rwlocks.
      
       - Support for a new faster system call ABI using the scv instruction on
         Power9 or later.
      
       - Drop support for the PROT_SAO mmap/mprotect flag as it will be
         unsupported on Power10 and future processors, leaving us with no way
         to implement the functionality it requests. This risks breaking
         userspace, though we believe it is unused in practice.
      
       - A bug fix for, and then the removal of, our custom stack expansion
         checking. We now allow stack expansion up to the rlimit, like other
         architectures.
      
       - Remove the remnants of our (previously disabled) topology update
         code, which tried to react to NUMA layout changes on virtualised
         systems, but was prone to crashes and other problems.
      
       - Add PMU support for Power10 CPUs.
      
       - A change to our signal trampoline so that we don't unbalance the link
         stack (branch return predictor) in the signal delivery path.
      
       - Lots of other cleanups, refactorings, smaller features and so on as
         usual.

      x86/mm/64: Do not dereference non-present PGD entries · 995909a4
      Joerg Roedel authored
      The code for preallocate_vmalloc_pages() was written under the
      assumption that the p4d_offset() and pud_offset() functions will perform
      present checks before dereferencing the parent entries.
      
      This assumption is wrong an leads to a bug in the code which causes the
      physical address found in the PGD be used as a page-table page, even if
      the PGD is not present.
      
      So the code flow currently is:
      
      	pgd = pgd_offset_k(addr);
      	p4d = p4d_offset(pgd, addr);
      	if (p4d_none(*p4d))
      		p4d = p4d_alloc(&init_mm, pgd, addr);
      
      This lacks a check for pgd_none() at least, the correct flow would be:
      
      	pgd = pgd_offset_k(addr);
      	if (pgd_none(*pgd))
      		p4d = p4d_alloc(&init_mm, pgd, addr);
      	else
      		p4d = p4d_offset(pgd, addr);
      
      But this is the same flow that the p4d_alloc() and the pud_alloc()
      functions use internally, so there is no need to duplicate them.
      
      Remove the p?d_none() checks from the function and just call into
      p4d_alloc() and pud_alloc() to correctly pre-allocate the PGD entries.

      arm64: kaslr: Use standard early random function · 9bceb80b
      Guenter Roeck authored
      Commit 58552408 ("random: random.h should include archrandom.h, not
      the other way around") tries to fix a problem with recursive inclusion
      of linux/random.h and arch/archrandom.h for arm64.  Unfortunately, this
      results in the following compile error if ARCH_RANDOM is disabled.
      
        arch/arm64/kernel/kaslr.c: In function 'kaslr_early_init':
        arch/arm64/kernel/kaslr.c:128:6: error: implicit declaration of function '__early_cpu_has_rndr'; did you mean '__early_pfn_to_nid'? [-Werror=implicit-function-declaration]
          if (__early_cpu_has_rndr()) {
              ^~~~~~~~~~~~~~~~~~~~
              __early_pfn_to_nid
        arch/arm64/kernel/kaslr.c:131:7: error: implicit declaration of function '__arm64_rndr' [-Werror=implicit-function-declaration]
           if (__arm64_rndr(&raw))
               ^~~~~~~~~~~~
      
      The problem is that arch/archrandom.h is only included from
      linux/random.h if ARCH_RANDOM is enabled.  If not, __arm64_rndr() and
      __early_cpu_has_rndr() are undeclared, causing the problem.
      
      Use arch_get_random_seed_long_early() instead of arm64 specific
      functions to solve the problem.

      thermal: don't make THERMAL_NETLINK 'default y' · 0f5d0a4c
      Linus Torvalds authored
      We just don't do that.  "default y" is for things that are needed for
      compatibility (when an old feature is made unconditional), or for things
      that are basically part of the infrastructure of a platform.
      
      And it can possibly be used for questions that don't enable code on
      their own, but are used to enable or disable a whole slew of other
      questions.
      
      A new feature that people aren't using is never 'default y', unless it
      cures cancer or ends world hunger.

       "The most notable changes are:

         - iomap embraced the use of returning ENOTBLK from a direct write to
           trigger falling back to a buffered write since ext4 already did
           this and btrfs wants it for their port.
      
         - iomap falls back to buffered writes if we're doing a direct write
           and the page cache invalidation after the flush fails; this was
           necessary to handle a corner case in the btrfs port.

      Linus Torvalds authored
      This reverts commit 8bb9bf24.
      
      It seems the vmalloc page tables aren't always preallocated in all
      situations, because Jason Donenfeld reports an oops with this commit:
      
        BUG: unable to handle page fault for address: ffffe8ffffd00608
        #PF: supervisor read access in kernel mode
        #PF: error_code(0x0000) - not-present page

         ret_from_fork+0x1f/0x30
        CR2: ffffe8ffffd00608
      
      and that page fault address is right in that vmalloc space, and we
      clearly don't have a PGD/P4D entry for it.
      
      Looking at the "Code:" line, the actual fault seems to come from the
      'pwq->wq' dereference at the top of the process_one_work() function:
      
              struct pool_workqueue *pwq = get_work_pwq(work);
              struct worker_pool *pool = worker->pool;
              bool cpu_intensive = pwq->wq->flags & WQ_CPU_INTENSIVE;
      
      so 'struct pool_workqueue *pwq' is the allocation that hasn't been
      synchronized across CPUs.
      
      Just revert for now, while Joerg figures out the cause.

       "This adds the sched_set_fifo*() encapsulation APIs to remove static
        priority level knowledge from non-scheduler code.
      
        The three APIs for non-scheduler code to set SCHED_FIFO are:
      
         - sched_set_fifo()
         - sched_set_fifo_low()
         - sched_set_normal()
      
        These are two FIFO priority levels: default (high), and a 'low'
        priority level, plus sched_set_normal() to set the policy back to
        non-SCHED_FIFO.
      
        Since the changes affect a lot of non-scheduler code, we kept this in
        a separate tree"

      fs: dlm: implement tcp graceful shutdown · 055923bf
      Alexander Aring authored
      During my code inspection I saw there is no implementation of a graceful
      shutdown for tcp. This patch will introduce a graceful shutdown for tcp
      connections. The shutdown is implemented synchronized as
      dlm_lowcomms_stop() is called to end all dlm communication. After shutdown
      is done, a lot of flush and closing functionality will be called. However
      I don't see a problem with that.
      
      The waitqueue for synchronize the shutdown has a timeout of 10 seconds, if
      timeout a force close will be exectued.

      fs: dlm: change handling of reconnects · ba3ab3ca
      Alexander Aring authored
      This patch changes the handling of reconnects. At first we only close
      the connection related to the communication failure. If we get a new
      connection for an already existing connection we close the existing
      connection and take the new one.
      
      This patch improves significantly the stability of tcp connections while
      running "tcpkill -9 -i $IFACE port 21064" while generating a lot of dlm
      messages e.g. on a gfs2 mount with many files. My test setup shows that a
      deadlock is "more" unlikely. Before this patch I wasn't able to get
      not a deadlock after 5 seconds. After this patch my observation is
      that it's more likely to survive after 5 seconds and more, but still a
      deadlock occurs after certain time. My guess is that there are still
      "segments" inside the tcp writequeue or retransmit queue which get dropped
      when receiving a tcp reset [1]. Hard to reproduce because the right message
      need to be inside these queues, which might even be in the 5 first seconds
      with this patch.

      received. The connection will probably reconnect anyway so. To not
      close the connection will reduce the number of possible failtures.
      As we don't have a different strategy to react on such scenario
      just keep going the connection and ignore the message.
