Matthew Garrett 547b524636 PCI: Use ROM images from firmware only if no other ROM source available
Mantas Mikulėnas reported that his graphics hardware failed to
initialise after commit f9a37be0f0 ("x86: Use PCI setup data").

The aim of this commit was to ensure that ROM images were available on
some Apple systems that don't expose the GPU ROM via any other source.
In this case, UEFI appears to have provided a broken ROM image that we
were using even though there was a perfectly valid ROM available via
other sources.  The simplest way to handle this seems to be to just
re-order pci_map_rom() and leave any firmare-supplied ROM to last.

Andy Honig a2c118bfab KVM: Fix bounds checking in ioapic indirect register reads (CVE-2013-1798)
If the guest specifies a IOAPIC_REG_SELECT with an invalid value and follows
that with a read of the IOAPIC_REG_WINDOW KVM does not properly validate
that request.  ioapic_read_indirect contains an
ASSERT(redir_index < IOAPIC_NUM_PINS), but the ASSERT has no effect in
non-debug builds.  In recent kernels this allows a guest to cause a kernel
oops by reading invalid memory.  In older kernels (pre-3.3) this allows a
guest to read from large ranges of host memory.

Tested: tested against apic unit tests.

Andy Honig 0b79459b48 KVM: x86: Convert MSR_KVM_SYSTEM_TIME to use gfn_to_hva_cache functions (CVE-2013-1797)
There is a potential use after free issue with the handling of
MSR_KVM_SYSTEM_TIME.  If the guest specifies a GPA in a movable or removable
memory such as frame buffers then KVM might continue to write to that
address even after it's removed via KVM_SET_USER_MEMORY_REGION.  KVM pins
the page in memory so it's unlikely to cause an issue, but if the user
space component re-purposes the memory previously used for the guest, then
the guest will be able to corrupt that memory.

Andy Honig c300aa64dd KVM: x86: fix for buffer overflow in handling of MSR_KVM_SYSTEM_TIME (CVE-2013-1796)
If the guest sets the GPA of the time_page so that the request to update the
time straddles a page then KVM will write onto an incorrect page.  The
write is done byusing kmap atomic to get a pointer to the page for the time
structure and then performing a memcpy to that page starting at an offset
that the guest controls.  Well behaved guests always provide a 32-byte aligned
address, however a malicious guest could use this to corrupt host kernel
memory.

Hannes Frederic Sowa 5a3da1fe95 inet: limit length of fragment queue hash table bucket lists
This patch introduces a constant limit of the fragment queue hash
table bucket list lengths. Currently the limit 128 is choosen somewhat
arbitrary and just ensures that we can fill up the fragment cache with
empty packets up to the default ip_frag_high_thresh limits. It should
just protect from list iteration eating considerable amounts of cpu.

If we reach the maximum length in one hash bucket a warning is printed.
This is implemented on the caller side of inet_frag_find to distinguish
between the different users of inet_fragment.c.

I dropped the out of memory warning in the ipv4 fragment lookup path,
because we already get a warning by the slab allocator.

This patch (as1637) cleans up the way ehci-hcd handles end-of-resume
port signalling.  When the PORT_RESUME bit in the port's status and
control register is cleared, we shouldn't be setting the PORT_SUSPEND
bit at the same time.  Not doing this doesn't seem to have hurt so
far, but we might as well do the right thing.

Also, the patch replaces an estimated value for what the port status
should be following a resume with the actual register value.

Expiration of the IAA watchdog is an unusual event and can lead to
problems; we need to know about it if it happens during debugging.  It
should not be necessary to set a "verbose" compilation option.

No behavioral changes other than the debug message.  Lots of apparent

Alan Stern 6d5df89762 USB: EHCI: decrease schedule-status poll timeout
This patch (as1657) decreases the timeout used by ehci-hcd for polling
the async and periodic schedule statuses.  The timeout is currently
set to 20 ms, which is much too high.  Controllers should always
update the schedule status within one or two ms of being told to do
so; if they don't then something is wrong.

Furthermore, bug reports have shown that sometimes controllers
(particularly those made by VIA) don't update the status bit at all,
even when the schedule does change state.  When this happens, polling
for 20 ms would cause an unnecessarily long delay.

The delay is reduced to somewhere between 2 and 4 ms, depending on the
slop allowed by the kernel's high-res timers.

Marcelo Tosatti c09664bb44 KVM: x86: fix deadlock in clock-in-progress request handling
There is a deadlock in pvclock handling:

cpu0:                                               cpu1:
kvm_gen_update_masterclock()
                                              kvm_guest_time_update()
 spin_lock(pvclock_gtod_sync_lock)
                                               local_irq_save(flags)

spin_lock(pvclock_gtod_sync_lock)

 kvm_make_mclock_inprogress_request(kvm)
  make_all_cpus_request()
   smp_call_function_many()

Now if smp_call_function_many() called by cpu0 tries to call function on
cpu1 there will be a deadlock.

Fix by moving pvclock_gtod_sync_lock protected section outside irq
disabled section.

Kevin Hilman f445f11eb2 KVM: allow host header to be included even for !CONFIG_KVM
The new context tracking subsystem unconditionally includes kvm_host.h
headers for the guest enter/exit macros.  This causes a compile
failure when KVM is not enabled.

Fix by adding an IS_ENABLED(CONFIG_KVM) check to kvm_host so it can
be included/compiled even when KVM is not enabled.

Mark M. Hoffman stopped working on the Linux kernel several years

even sure if his e-mail address still works.

I can take over 3 drivers he was responsible for, the 4th one will
fall down to the subsystem maintainer.

Also give Mark credit for all the good work he did.

Dave Chinner e001873853 xfs: ensure we capture IO errors correctly
Failed buffer readahead can leave the buffer in the cache marked
with an error. Most callers that then issue a subsequent read on the
buffer do not zero the b_error field out, and so we may incorectly
detect an error during IO completion due to the stale error value
left on the buffer.

Avoid this problem by zeroing the error before IO submission. This
ensures that the only IO errors that are detected those captured
from are those captured from bio submission or completion.

Eric Dumazet 0d4f060861 tcp: dont handle MTU reduction on LISTEN socket
When an ICMP ICMP_FRAG_NEEDED (or ICMPV6_PKT_TOOBIG) message finds a
LISTEN socket, and this socket is currently owned by the user, we
set TCP_MTU_REDUCED_DEFERRED flag in listener tsq_flags.

This is bad because if we clone the parent before it had a chance to
clear the flag, the child inherits the tsq_flags value, and next
tcp_release_cb() on the child will decrement sk_refcnt.

Result is that we might free a live TCP socket, as reported by
Dormando.

IPv4: Attempt to release TCP socket in state 1

Fix this issue by testing sk_state against TCP_LISTEN early, so that we
set TCP_MTU_REDUCED_DEFERRED on appropriate sockets (not a LISTEN one)

This bug was introduced in commit 563d34d057
(tcp: dont drop MTU reduction indications)

Dmitry Torokhov f8264340e6 USB: xhci - fix bit definitions for IMAN register
According to XHCI specification (5.5.2.1) the IP is bit 0 and IE is bit 1
of IMAN register. Previously their definitions were reversed.

Even though there are no ill effects being observed from the swapped
definitions (because IMAN_IP is RW1C and in legacy PCI case we come in
with it already set to 1 so it was clearing itself even though we were
setting IMAN_IE instead of IMAN_IP), we should still correct the values.

This patch should be backported to kernels as old as 2.6.36, that
contain the commit 4e833c0b87 "xhci: don't
re-enable IE constantly".
