Some changes to the TCP fastopen code to make it more robust
against future changes in the choice of key/cookie size, etc.
- Instead of keeping the SipHash key in an untyped u8[] buffer
and casting it to the right type upon use, use the correct
type directly. This ensures that the key will appear at the
correct alignment if we ever change the way these data
structures are allocated. (Currently, they are only allocated
via kmalloc so they always appear at the correct alignment)
- Use DIV_ROUND_UP when sizing the u64[] array to hold the
cookie, so it is always of sufficient size, even if
TCP_FASTOPEN_COOKIE_MAX is no longer a multiple of 8.
- Drop the 'len' parameter from the tcp_fastopen_reset_cipher()
function, which is no longer used.
- Add endian swabbing when setting the keys and calculating the hash,
to ensure that cookie values are the same for a given key and
source/destination address pair regardless of the endianness of
the server.
Note that none of these are functional changes wrt the current
state of the code, with the exception of the swabbing, which only
affects big endian systems.

When transmitting certain PTP frames, e.g. SYNC and DELAY_REQ, the
PTP daemon, e.g. ptp4l, is polling the driver for the frame transmit
hardware timestamp. The polling will most likely timeout if the tx
coalesce is enabled due to the Interrupt-on-Completion (IC) bit is
not set in tx descriptor for those frames.
This patch will ignore the tx coalesce parameter and set the IC bit
when transmitting PTP frames which need to report out the frame
transmit hardware timestamp to user space.

When ADDSUB bit is set, the system time seconds field is calculated as
the complement of the seconds part of the update value.
For example, if 3.000000001 seconds need to be subtracted from the
system time, this field is calculated as
2^32 - 3 = 4294967296 - 3 = 0x100000000 - 3 = 0xFFFFFFFD
Previously, the 0x100000000 is mistakenly written as 100000000.
This is further simplified from
sec = (0x100000000ULL - sec);
to
sec = -sec;

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.

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.

PCI: let pci_disable_link_state propagate errors
Drivers like r8169 rely on pci_disable_link_state() having disabled
certain ASPM link states. If OS can't control ASPM then
pci_disable_link_state() turns into a no-op w/o informing the caller.
The driver therefore may falsely assume the respective ASPM link
states are disabled. Let pci_disable_link_state() propagate errors
to the caller, enabling the caller to react accordingly.
I'd propose to let this series go through the netdev tree if the PCI
core extension is acked by the PCI people.

Certain chip version / board combinations have massive problems if
ASPM is active. If BIOS enables ASPM and doesn't let OS control it,
then we may have a problem with the current code. Therefore check the
return code of pci_disable_link_state() and don't enable ASPM in the
network chip if OS can't control ASPM.

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

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
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.

Pull still more SPDX updates from Greg KH:
"Another round of SPDX updates for 5.2-rc6
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

ip netns exec ns1 ip a a dev eth0 10.0.0.7/24

ip netns exec ns2 ip a a dev vlan 10.0.0.8/24

brctl addif br0 veth2
bridge vlan add dev veth1 vid 200 pvid untagged
bridge vlan add dev veth2 vid 200
A two fragment packet sent from ns2 contains the vlan tag 200. In the
bridge conntrack, this packet will defrag to one skb with fraglist.
When the packet is forwarded to ns1 through veth1, the first skb vlan
tag will be cleared by the "untagged" flags. But the vlan tag in the
second skb is still tagged, so the second fragment ends up with tag 200
to ns1. So if the first fragment packet doesn't contain the vlan tag,
all of the remain should not contain vlan tag.

When CONFIG_IPV6 is disabled, the bridge netfilter code
produces a link error:
ERROR: "br_ip6_fragment" [net/bridge/netfilter/nf_conntrack_bridge.ko] undefined!
ERROR: "nf_ct_frag6_gather" [net/bridge/netfilter/nf_conntrack_bridge.ko] undefined!
The problem is that it assumes that whenever IPV6 is not a loadable
module, we can call the functions direction. This is clearly
not true when IPV6 is disabled.
There are two other functions defined like this in linux/netfilter_ipv6.h,
so change them all the same way.

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.

The setting of i_blocks, which is calculated from i_size, has got
accidentally misordered relative to the setting of i_size when initially
setting up an inode. Further, i_blocks isn't updated by afs_apply_status()
when the size is updated.
To fix this, break the i_size/i_blocks setting out into a helper function
and call it from both places.
