Previously in squashfs_readpage() when copying data into the page
cache, it used the length of the datablock read from the filesystem
(after decompression). However, if the filesystem has been corrupted
this data block may be short, which will leave pages unfilled.
The fix for this is to compute the expected number of bytes to copy
from the inode size, and use this to detect if the block is short.

The squashfs fragment reading code doesn't actually verify that the
fragment is inside the fragment table. The end result _is_ verified to
be inside the image when actually reading the fragment data, but before
that is done, we may end up taking a page fault because the fragment
table itself might not even exist.
Another report from Anatoly and his endless squashfs image fuzzing.

There were two report of boot failure cased by trampoline placed into
a reserved memory region. It can happen on machines that don't report
EBDA correctly.
Fix the problem by re-validating the found address against the E820 table.
If the address is in a reserved area, find the next usable region below the
initial address.

The patch to fix the case where a lock request was interrupted ended up
changing default handling of errors such as NFS4ERR_DENIED and caused the
client to immediately resend the lock request. Let's do a partial revert
of that request so that the default is now to exit, but change the way
we handle resends to take into account the fact that the user may have
interrupted the request.

Commit 2c4541e24c55 ("mm: use vma_init() to initialize VMAs on stack and
data segments") tried to initialize various left-over ad-hoc vma's
"properly", but actually made things worse for the temporary vma's used
for TLB flushing.
vma_init() doesn't actually initialize all of the vma, just a few
fields, so doing something like
- struct vm_area_struct vma = { .vm_mm = tlb->mm, };
+ struct vm_area_struct vma;
+
+ vma_init(&vma, tlb->mm);
was actually very bad: instead of having a nicely initialized vma with
every field but "vm_mm" zeroed, you'd have an entirely uninitialized vma
with only a couple of fields initialized. And they weren't even fields
that the code in question mostly cared about.
The flush_tlb_range() function takes a "struct vma" rather than a
"struct mm_struct", because a few architectures actually care about what
kind of range it is - being able to only do an ITLB flush if it's a
range that doesn't have data accesses enabled, for example. And all the
normal users already have the vma for doing the range invalidation.
But a few people want to call flush_tlb_range() with a range they just
made up, so they also end up using a made-up vma. x86 just has a
special "flush_tlb_mm_range()" function for this, but other
architectures (arm and ia64) do the "use fake vma" thing instead, and
thus got caught up in the vma_init() changes.
At the same time, the TLB flushing code really doesn't care about most
other fields in the vma, so vma_init() is just unnecessary and
pointless.
This fixes things by having an explicit "this is just an initializer for
the TLB flush" initializer macro, which is used by the arm/arm64/ia64
people who mis-use this interface with just a dummy vma.

Delete the old VM_BUG_ON_VMA() from zap_pmd_range(), which asserted
that mmap_sem must be held when splitting an "anonymous" vma there.
Whether that's still strictly true nowadays is not entirely clear,
but the danger of sometimes crashing on the BUG is now fairly clear.
Even with the new stricter rules for anonymous vma marking, the
condition it checks for can possible trigger. Commit 44960f2a7b63
("staging: ashmem: Fix SIGBUS crash when traversing mmaped ashmem
pages") is good, and originally I thought it was safe from that
VM_BUG_ON_VMA(), because the /dev/ashmem fd exposed to the user is
disconnected from the vm_file in the vma, and madvise(,,MADV_REMOVE)
insists on VM_SHARED.
But after I read John's earlier mail, drawing attention to the
vfs_fallocate() in there: I may be wrong, and I don't know if Android
has THP in the config anyway, but it looks to me like an
unmap_mapping_range() from ashmem's vfs_fallocate() could hit precisely
the VM_BUG_ON_VMA(), once it's vma_is_anonymous().

Anatoly continues to find issues with fuzzed squashfs images.
This time, corrupt, missing, or undersized data for the page filling
wasn't checked for, because the squashfs_{copy,read}_cache() functions
did the squashfs_copy_data() call without checking the resulting data
size.
Which could result in the page cache pages being incompletely filled in,
and no error indication to the user space reading garbage data.
So make a helper function for the "fill in pages" case, because the
exact same incomplete sequence existed in two places.
[ I should have made a squashfs branch for these things, but I didn't
intend to start doing them in the first place.
My historical connection through cramfs is why I got into looking at
these issues at all, and every time I (continue to) think it's a
one-off.
Because _this_ time is always the last time. Right? - Linus ]

This was bisected back to commit bfd40eaff5ab ("mm: fix
vma_is_anonymous() false-positives").
create_mspace_with_base() in the trace above, utilizes ashmem, and with
ashmem, for shared mappings we use shmem_zero_setup(), which sets the
vma->vm_ops to &shmem_vm_ops. But for private ashmem mappings nothing
sets the vma->vm_ops.
Looking at the problematic patch, it seems to add a requirement that one
call vma_set_anonymous() on a vma, otherwise the dummy_vm_ops will be
used. Using the dummy_vm_ops seem to triggger SIGBUS when traversing
unmapped pages.
Thus, this patch adds a call to vma_set_anonymous() for ashmem private
mappings and seems to avoid the reported problem.

Commit bfd40eaff5ab ("mm: fix vma_is_anonymous() false-positives") made
newly allocated vma's have a dummy vm_ops field so that they wouldn't be
mistaken for anonymous mappings, and if you wanted an anonymous vma you
had to explicitly say so by calling "vma_set_anonymous()" on it.
However, it missed the two special vmas that ia64 processes have: the
register backing store and the NaT page. So they wouldn't actually act
like anonymous ranges, and page faults on them caused a SIGBUS rather
than the creation of a new anon page in them.
That obviously will make any ia64 binary very unhappy indeed, and the
boot fails early.

With the optimizations for TLB invalidation from commit 0cef77c7798a
("powerpc/64s/radix: flush remote CPUs out of single-threaded
mm_cpumask"), the scope of a TLBI (global vs. local) can now be
influenced by the value of the 'copros' counter of the memory context.
When calling mm_context_remove_copro(), the 'copros' counter is
decremented first before flushing. It may have the unintended side
effect of sending local TLBIs when we explicitly need global
invalidations in this case. Thus breaking any nMMU user in a bad and
unpredictable way.
Fix it by flushing first, before updating the 'copros' counter, so
that invalidations will be global.

In commit ab123fe071c9 ("enic: handle mtu change for vf properly")
ASSERT_RTNL() is added to _enic_change_mtu() to prevent it from being
called without rtnl held. enic_probe() calls enic_change_mtu()
without rtnl held. At this point netdev is not registered yet.
Remove call to enic_change_mtu and assign the mtu to netdev->mtu.

ip_frag_queue() might call pskb_pull() on one skb that
is already in the fragment queue.
We need to take care of possible truesize change, or we
might have an imbalance of the netns frags memory usage.
IPv6 is immune to this bug, because RFC5722, Section 4,
amended by Errata ID 3089 states :
When reassembling an IPv6 datagram, if
one or more its constituent fragments is determined to be an
overlapping fragment, the entire datagram (and any constituent
fragments) MUST be silently discarded.

We currently check current frags memory usage only when
a new frag queue is created. This allows attackers to first
consume the memory budget (default : 4 MB) creating thousands
of frag queues, then sending tiny skbs to exceed high_thresh
limit by 2 to 3 order of magnitude.
Note that before commit 648700f76b03 ("inet: frags: use rhashtables
for reassembly units"), work queue could be starved under DOS,
getting no cpu cycles.
After commit 648700f76b03, only the per frag queue timer can eventually
remove an incomplete frag queue and its skbs.

After introduction of the cited commit, mlx5e_build_nic_params
receives the netdevice mtu in order to set the sw_mtu of mlx5e_params.
For enhanced IPoIB, the netdevice mtu is not set in this stage,
therefore, the initial sw_mtu equals zero. As a result, the hw_mtu
of the receive queue will be calculated incorrectly causing traffic
issues.
To fix this issue, query for port mtu before building the nic params.

When a PCI device is detected, pdev->is_added is set to 1 and proc and
sysfs entries are created.
When the device is removed, pdev->is_added is checked for one and then
device is detached with clearing of proc and sys entries and at end,
pdev->is_added is set to 0.
is_added and is_busmaster are bit fields in pci_dev structure sharing same
memory location.
A strange issue was observed with multiple removal and rescan of a PCIe
NVMe device using sysfs commands where is_added flag was observed as zero
instead of one while removing device and proc,sys entries are not cleared.
This causes issue in later device addition with warning message
"proc_dir_entry" already registered.
Debugging revealed a race condition between the PCI core setting the
is_added bit in pci_bus_add_device() and the NVMe driver reset work-queue
setting the is_busmaster bit in pci_set_master(). As these fields are not
handled atomically, that clears the is_added bit.
Move the is_added bit to a separate private flag variable and use atomic
functions to set and retrieve the device addition state. This avoids the
race because is_added no longer shares a memory location with is_busmaster.

Dynamic boosting of HWP performance on IO wake showed significant
improvement to IO workloads. This series was intended for Skylake Xeon
platforms only and feature was enabled by default based on CPU model
number.
But some Xeon platforms reused the Skylake desktop CPU model number. This
caused some undesirable side effects to some graphics workloads. Since
they are heavily IO bound, the increase in CPU performance decreased the
power available for GPU to do its computing and hence decrease in graphics
benchmark performance.
For example on a Skylake desktop, GpuTest benchmark showed average FPS
reduction from 529 to 506.
This change makes sure that HWP boost feature is only enabled for Skylake
server platforms by using ACPI FADT preferred PM Profile. If some desktop
users wants to get benefit of boost, they can still enable boost from
intel_pstate sysfs attribute "hwp_dynamic_boost".

This bug was introduced by:
commit 15a3e845b01c ("perf/x86/intel/uncore: Fix SBOX support for Broadwell CPUs")
The index of "QPI Port 2 filter" was hardcode to 2, but this conflicts with the
index of "PCU.3" which is "HSWEP_PCI_PCU_3", which equals to 2 as well.
To fix the conflict, the hardcoded index needs to be cleaned up:
- introduce a new enumerator "BDX_PCI_QPI_PORT2_FILTER" for "QPI Port 2
filter" on Broadwell,
- increase UNCORE_EXTRA_PCI_DEV_MAX by one,
- clean up the hardcoded index.

I hit the following problem when I tried to use bpftool
to dump a percpu array.
$ sudo ./bpftool map show
61: percpu_array name stub flags 0x0
key 4B value 4B max_entries 1 memlock 4096B
...
$ sudo ./bpftool map dump id 61
bpftool: malloc.c:2406: sysmalloc: Assertion
`(old_top == initial_top (av) && old_size == 0) || \
((unsigned long) (old_size) >= MINSIZE && \
prev_inuse (old_top) && \
((unsigned long) old_end & (pagesize - 1)) == 0)'
failed.
Aborted
Further debugging revealed that this is due to
miscommunication between bpftool and kernel.
For example, for the above percpu_array with value size of 4B.
The map info returned to user space has value size of 4B.
In bpftool, the values array for lookup is allocated like:
info->value_size * get_possible_cpus() = 4 * get_possible_cpus()
In kernel (kernel/bpf/syscall.c), the values array size is
rounded up to multiple of 8.
round_up(map->value_size, 8) * num_possible_cpus()
= 8 * num_possible_cpus()
So when kernel copies the values to user buffer, the kernel will
overwrite beyond user buffer boundary.
This patch fixed the issue by allocating and stepping through
percpu map value array properly in bpftool.
