      arm64: vdso: Substitute gettimeofday() with C implementation · 28b1a824
      Vincenzo Frascino authored
      To take advantage of the commonly defined vdso interface for gettimeofday()
      the architectural code requires an adaptation.
      
      Re-implement the gettimeofday VDSO in C in order to use lib/vdso.
      
      With the new implementation arm64 gains support for CLOCK_BOOTTIME
      and CLOCK_TAI.
      
      [ tglx: Reformatted the function line breaks ]

      timekeeping: Provide a generic update_vsyscall() implementation · 44f57d78
      Vincenzo Frascino authored
      The new generic VDSO library allows to unify the update_vsyscall[_tz]()
      implementations.
      
      Provide a generic implementation based on the x86 code and the bindings
      which need to be implemented in architecture specific code.

      lib/vdso: Provide generic VDSO implementation · 00b26474
      Vincenzo Frascino authored
      In the last few years the kernel gained quite some architecture specific
      vdso implementations which contain very similar code.
      
      Introduce a generic VDSO implementation of gettimeofday() which will be
      shareable between architectures once they are converted over.
      
      The implementation is based on the current x86 VDSO code.

       "This is a frustratingly large batch at rc5. Some of these were sent
        earlier but were missed by me due to being distracted by other things,
        and some took a while to track down due to needing manual bisection on
        old hardware. But still we clearly need to improve our testing of KVM,
        and of 32-bit, so that we catch these earlier.
      
        Summary: seven fixes, all for bugs introduced this cycle.
      
         - The commit to add KASAN support broke booting on 32-bit SMP
           machines, due to a refactoring that moved some setup out of the
           secondary CPU path.
      
         - A fix for another 32-bit SMP bug introduced by the fast syscall
           entry implementation for 32-bit BOOKE. And a build fix for the same
           commit.
      
         - Our change to allow the DAWR to be force enabled on Power9
           introduced a bug in KVM, where we clobber r3 leading to a host
           crash.
      
         - The same commit also exposed a previously unreachable bug in the
           nested KVM handling of DAWR, which could lead to an oops in a
           nested host.
      
         - One of the DMA reworks broke the b43legacy WiFi driver on some
           people's powermacs, fix it by enabling a 30-bit ZONE_DMA on 32-bit.
      
         - A fix for TLB flushing in KVM introduced a new bug, as it neglected
           to also flush the ERAT, this could lead to memory corruption in the
           guest.

      Bluetooth: Fix regression with minimum encryption key size alignment · 693cd8ce
      Marcel Holtmann authored
      When trying to align the minimum encryption key size requirement for
      Bluetooth connections, it turns out doing this in a central location in
      the HCI connection handling code is not possible.
      
      Original Bluetooth version up to 2.0 used a security model where the
      L2CAP service would enforce authentication and encryption.  Starting
      with Bluetooth 2.1 and Secure Simple Pairing that model has changed into
      that the connection initiator is responsible for providing an encrypted
      ACL link before any L2CAP communication can happen.
      
      Now connecting Bluetooth 2.1 or later devices with Bluetooth 2.0 and
      before devices are causing a regression.  The encryption key size check
      needs to be moved out of the HCI connection handling into the L2CAP
      channel setup.
      
      To achieve this, the current check inside hci_conn_security() has been
      moved into l2cap_check_enc_key_size() helper function and then called
      from four decisions point inside L2CAP to cover all combinations of
      Secure Simple Pairing enabled devices and device using legacy pairing
      and legacy service security model.
      
      Fixes: d5bb334a ("Bluetooth: Align minimum encryption key size for LE and BR/EDR connections")

      tcp: refine memory limit test in tcp_fragment() · b6653b36
      Eric Dumazet authored
      tcp_fragment() might be called for skbs in the write queue.
      
      Memory limits might have been exceeded because tcp_sendmsg() only
      checks limits at full skb (64KB) boundaries.
      
      Therefore, we need to make sure tcp_fragment() wont punish applications
      that might have setup very low SO_SNDBUF values.

        us and people taking trips, I expect the next weeks leading up to the

        This has two simple, no brainer fixes for the EFA driver.
      
        Then it has ten not quite so simple fixes for the hfi1 driver. The
        problem with them is that they aren't simply one liner typo fixes.
        They're still fixes, but they're more complex issues like livelock
        under heavy load where the answer was to change work queue usage and
        spinlock usage to resolve the problem, or issues with orphaned
        requests during certain types of failures like link down which
        required some more complex work to fix too. They all look like
        legitimate fixes to me, they just aren't small like I wish they were.

      x86/vdso: Prevent segfaults due to hoisted vclock reads · ff17bbe0
      Andy Lutomirski authored
      GCC 5.5.0 sometimes cleverly hoists reads of the pvclock and/or hvclock
      pages before the vclock mode checks.  This creates a path through
      vclock_gettime() in which no vclock is enabled at all (due to disabled
      TSC on old CPUs, for example) but the pvclock or hvclock page
      nevertheless read.  This will segfault on bare metal.
      
      This fixes commit 459e3a21 ("gcc-9: properly declare the
      {pv,hv}clock_page storage") in the sense that, before that commit, GCC
      didn't seem to generate the offending code.  There was nothing wrong
      with that commit per se, and -stable maintainers should backport this to
      all supported kernels regardless of whether the offending commit was
      present, since the same crash could just as easily be triggered by the
      phase of the moon.
      
      On GCC 9.1.1, this doesn't seem to affect the generated code at all, so
      I'm not too concerned about performance regressions from this fix.

      Jon Hunter reports:
        "I have been noticing intermittent failures with a system suspend test on
         some of our machines that have a NFS mounted root file-system. Bisecting
         this issue points to your commit 43123581 ("SUNRPC: Declare RPC

         appear to resolve the problem.
      
         The cause of the suspend failure appears to be a long delay observed
         sometimes when resuming from suspend, and this is causing our test to
         timeout."

      NFS4: Only set creation opendata if O_CREAT · 90910519
      Benjamin Coddington authored
      We can end up in nfs4_opendata_alloc during task exit, in which case
      current->fs has already been cleaned up.  This leads to a crash in
      current_umask().
      
      Fix this by only setting creation opendata if we are actually doing an open
      with O_CREAT.  We can drop the check for NULL nfs4_open_createattrs, since
      O_CREAT will never be set for the recovery path.

        Another 5000+ files are fixed up, so our overall totals are:

      ARM: 8867/1: vdso: pass --be8 to linker if necessary · c5d0e49e
      Jason A. Donenfeld authored
      The commit fe00e50b ("ARM: 8858/1: vdso: use $(LD) instead of $(CC)
      to link VDSO") removed the passing of CFLAGS, since ld doesn't take
      those directly. However, prior, big-endian ARM was relying on gcc to
      translate its -mbe8 option into ld's --be8 option. Lacking this, ld
      generated be32 code, making the VDSO generate SIGILL when called by
      userspace.
      
      This commit passes --be8 if CONFIG_CPU_ENDIAN_BE8 is enabled.

       "This is mainly a couple of email address updates to MAINTAINERS, but
        we've also fixed a UAPI build issue with musl libc and an accidental

        weak symbol.
      
        There are a couple of outstanding issues that have been reported, but
        it doesn't look like they're new and we're still a long way off from
        fully debugging them.

         - Fix use of #include in UAPI headers for compatability with musl libc
