Given that the entry_*.S changes for this functionality are somewhat
tricky, make sure the paths are tested every boot, instead of on the
rare occasion when we trip an INT3 while rewriting text.

Currently pt_regs on x86_32 has an oddity in that kernel regs
(!user_mode(regs)) are short two entries (esp/ss). This means that any
code trying to use them (typically: regs->sp) needs to jump through
some unfortunate hoops.

Change the entry code to fix this up and create a full pt_regs frame.

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.

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

(https://github.com/xairy/kernel-exploits/tree/master/CVE-2017-7308)

The goals of this change:

 - Pin specific bits (SMEP, SMAP, and UMIP) when writing CR4.

 - Avoid setting the bits too early (they must become pinned only after
   CPU feature detection and selection has finished).

 - Pinning mask needs to be read-only during normal runtime.

 - Pinning needs to be checked after write to validate the cr4 state

Using __ro_after_init on the mask is done so it can't be first disabled
with a malicious write.

Since these bits are global state (once established by the boot CPU and
kernel boot parameters), they are safe to write to secondary CPUs before
those CPUs have finished feature detection. As such, the bits are set at
the first cr4 write, so that cr4 write bugs can be detected (instead of
silently papered over). This uses a few bytes less storage of a location we
don't have: read-only per-CPU data.

A check is performed after the register write because an attack could just
skip directly to the register write. Such a direct jump is possible because
of how this function may be built by the compiler (especially due to the
removal of frame pointers) where it doesn't add a stack frame (function
exit may only be a retq without pops) which is sufficient for trivial
exploitation like in the timer overwrites mentioned above).

The asm argument constraints gain the "+" modifier to convince the compiler
that it shouldn't make ordering assumptions about the arguments or memory,
and treat them as changed.

x86/vdso: Prevent segfaults due to hoisted vclock reads

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.

state before setting new state", 2019-05-02) broke evmcs_test because the

covers kvm_state->hdr.vmx.vmxon_pa == -1ull, that is quite ugly.

Instead, this patch moves checks earlier in the function and
conditionalizes them on kvm_state->hdr.vmx.vmxon_pa, so that

KVM: PPC: Book3S HV: Invalidate ERAT when flushing guest TLB entries

When a guest vcpu moves from one physical thread to another it is
necessary for the host to perform a tlb flush on the previous core if
another vcpu from the same guest is going to run there. This is because the
guest may use the local form of the tlb invalidation instruction meaning
stale tlb entries would persist where it previously ran. This is handled
on guest entry in kvmppc_check_need_tlb_flush() which calls
flush_guest_tlb() to perform the tlb flush.

Previously the generic radix__local_flush_tlb_lpid_guest() function was
used, however the functionality was reimplemented in flush_guest_tlb()
to avoid the trace_tlbie() call as the flushing may be done in real
mode. The reimplementation in flush_guest_tlb() was missing an erat
invalidation after flushing the tlb.

This lead to observable memory corruption in the guest due to the
caching of stale translations. Fix this by adding the erat invalidation.

inet: clear num_timeout reqsk_alloc()

KMSAN caught uninit-value in tcp_create_openreq_child() [1]
This is caused by a recent change, combined by the fact
that TCP cleared num_timeout, num_retrans and sk fields only
when a request socket was about to be queued.

Under syncookie mode, a temporary request socket is used,
and req->num_timeout could contain garbage.

Lets clear these three fields sooner, there is really no
point trying to defer this and risk other bugs.

PCI/P2PDMA: Ignore root complex whitelist when an IOMMU is present

Presently, there is no path to DMA map P2PDMA memory, so if a TLP targeting
this memory hits the root complex and an IOMMU is present, the IOMMU will
reject the transaction, even if the RC would support P2PDMA.

So until the kernel knows to map these DMA addresses in the IOMMU, we
should not enable the whitelist when an IOMMU is present.
