In theory, nothing prevents the compiler from write-tearing PTEs, or
split PTE writes. These partially-modified PTEs can be fetched by other
cores and cause mayhem. I have not really encountered such case in
real-life, but it does seem possible.
For example, the compiler may try to do something creative for
kvm_set_pte_rmapp() and perform multiple writes to the PTE.

KVM/ARM Fixes for v4.7-rc2
Fixes for the vgic, 2 of the patches address a bug introduced in v4.6
while the rest are for the new vgic.
|
|
When changing the active bit from an MMIO trap, we decide to
explode if the intid is that of a private interrupt.
This flawed logic comes from the fact that we were assuming that
kvm_vcpu_kick() as called by kvm_arm_halt_vcpu() would not return before
the called vcpu responded, but this is not the case, so we need to
perform this wait even for private interrupts.
Dropping the BUG_ON seems like the right thing to do.

The Kconfig options I added to work around broken compilation ended
up screwing up things more, as I used the wrong symbol to control
compilation of the file, resulting in IPv6 fou support to never be built
into the kernel.
Changing CONFIG_NET_FOU_IPV6_TUNNELS to CONFIG_IPV6_FOU fixes that
problem, I had renamed the symbol in one location but not the other,
and as the file is never being used by other kernel code, this did not
lead to a build failure that I would have caught.
After that fix, another issue with the same patch becomes obvious, as we
'select INET6_TUNNEL', which is related to IPV6_TUNNEL, but not the same,
and this can still cause the original build failure when IPV6_TUNNEL is
not built-in but IPV6_FOU is. The fix is equally trivial, we just need
to select the right symbol.
I have successfully build 350 randconfig kernels with this patch
and verified that the driver is now being built.

Now we cannot distinguish that one sk is a udp or sctp style when
we use ss to dump sctp_info. it's necessary to dump it as well.
For sctp_diag, ss support is not officially available, thus there
are no official users of this yet, so we can add this field in the
middle of sctp_info without breaking user API.
v1->v2:
- move 'sctpi_s_type' field to the end of struct sctp_info, so
that it won't cause incompatibility with applications already
built.
- add __reserved3 in sctp_info to make sure sctp_info is 8-byte
alignment.

The MAC address of the physical interface is only copied to the VLAN
when it is first created, resulting in an inconsistency after MAC
address changes of only newly created VLANs having an up-to-date MAC.
The VLANs should continue inheriting the MAC address of the physical
interface until the VLAN MAC address is explicitly set to any value.
This allows IPv6 EUI64 addresses for the VLAN to reflect any changes
to the MAC of the physical interface and thus for DAD to behave as
expected.

This bug was there when the driver was first added in back in year 2000.
It causes a Smatch warning:
drivers/atm/firestream.c:849 process_incoming()
error: buffer overflow 'res_strings' 60 <= 63
There are supposed to be 64 entries in this array and the missing
strings are clearly in the 30 40 range. I added them as reserved 37 to
reserved 40. It's possible that strings are really supposed to be added
in the middle instead of at the end, but this approach is safe, in that
it fixes the bug and doesn't break anything that wasn't already broken.

- Flush GPIO direction setting before locking a GPIO as an IRQ: some
electronics or other poking around in the registers behind our back
may have happened, so flush the direction status before trying to
lock the line for use by IRQs.
- Bail out silently when asked to perform operations on NULL GPIO
descriptors. That is what all the get_*_optional() is about: we
get optional GPIO handles, if they are not there, we get NULL.
- Handle compatible ioctl() correctly: we need to convert the ioctl()

The GICv3 backend of the vgic is quite barrier heavy, in order
to ensure synchronization of the system registers and the
memory mapped view for a potential GICv2 guest.
But when the guest is using a GICv3 model, there is absolutely
no need to execute all these heavy barriers, and it is actually
beneficial to avoid them altogether.
This patch makes the synchonization conditional, and ensures
that we do not change the EL1 SRE settings if we do not need to.

Both our GIC emulations are "strict", in the sense that we either
emulate a GICv2 or a GICv3, and not a GICv3 with GICv2 legacy
support.
But when running on a GICv3 host, we still allow the guest to
tinker with the ICC_SRE_EL1 register during its time slice:
it can switch SRE off, observe that it is off, and yet on the
next world switch, find the SRE bit to be set again. Not very
nice.
An obvious solution is to always trap accesses to ICC_SRE_EL1
(by clearing ICC_SRE_EL2.Enable), and to let the handler return
the programmed value on a read, or ignore the write.
That way, the guest can always observe that our GICv3 is SRE==1
only.

2) resample the line level and propagate it to the pending state
But these two actions shouldn't be linked, and we should *always*
