    With 5.2.0-rc5 I can easily trigger this with lockdep and iommu=pt:

    domain_context_mapping_one() is taking device_domain_lock first then
    iommu lock, while dmar_insert_one_dev_info() is doing the reverse.

    That should be introduced by commit:

    7560cc3ca7d9 ("iommu/vt-d: Fix lock inversion between iommu->lock and
    device_domain_lock", 2019-05-27)

    So far I still cannot figure out how the previous deadlock was
    triggered (I cannot find iommu lock taken before calling of
    iommu_flush_dev_iotlb()), however I'm pretty sure that that change
    should be incomplete at least because it does not fix all the places
    so we're still taking the locks in different orders, while reverting
    that commit is very clean to me so far that we should always take
    device_domain_lock first then the iommu lock.

    We can continue to try to find the real culprit mentioned in
    7560cc3ca7d9, but for now I think we should revert it to fix current
    breakage.

  • Pull powerpc fixes from Michael Ellerman:
    "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.

    Thanks to: Aaro Koskinen, Christoph Hellwig, Christophe Leroy, Larry
    Finger, Michael Neuling, Suraj Jitindar Singh"

  • 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: d5bb334a8e17 ("Bluetooth: Align minimum encryption key size for LE and BR/EDR connections")

  • 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.

  • Pull rdma fixes from Doug Ledford:
    "This is probably our last -rc pull request. We don't have anything
    else outstanding at the moment anyway, and with the summer months on
    us and people taking trips, I expect the next weeks leading up to the
    merge window to be pretty calm and sedate.

    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.

  • 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 459e3a21535a ("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.

  • We can end up in nfs4_opendata_alloc during task exit, in which case

    Fix this by only setting creation opendata if we are actually doing an open

    O_CREAT will never be set for the recovery path.

    Here is what I am guessing is going to be the last "big" SPDX update
    for 5.2. It contains all of the remaining GPLv2 and GPLv2+ updates
    that were "easy" to determine by pattern matching. The ones after this
    are going to be a bit more difficult and the people on the spdx list
    will be discussing them on a case-by-case basis now.

    Another 5000+ files are fixed up, so our overall totals are:
    Files checked: 64545
    Files with SPDX: 45529

    Compared to the 5.1 kernel which was:
    Files checked: 63848
    Files with SPDX: 22576

    This is a huge improvement.

    Also, we deleted another 20000 lines of boilerplate license crud,
    always nice to see in a diffstat"

  • A couple of fixes for vmwgfx. Two fixes for a DMA sg-list debug warning
    message. These are not cc'd stable since there is no evidence of actual

  • The commit fe00e50b2db8 ("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.
