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.

The periphery can't be accessed before we set the
INIT_DONE bit which initializes the device.
A previous patch added a reconfiguration of the MSI-X
tables upon resume, but at that point in the flow,
INIT_DONE wasn't set. Since the reconfiguration of the
MSI-X tables require periphery access, it failed.
The difference between WoWLAN and without WoWLAN is that
in WoWLAN, iwl_trans_pcie_d3_suspend clears the INIT_DONE
without clearing the STATUS_DEVICE_ENABLED bit in the
software status. Because of that, the resume code thinks
that the device is enabled, but the INIT_DONE bit has been
cleared.
To fix this, don't reconfigure the MSI-X tables in case
WoWLAN is enabled. It will be done in
iwl_trans_pcie_d3_resume anyway.

the same arch of using used and free lists, but different

Use the new structures, hw dependent, to manage the lists.
bd, the free list, uses the iwl_rx_transfer_desc,
in which the vid is stored in the structs' rbid
field, and the page address in the addr field.
used_bd, the used list, uses the iwl_rx_completion_desc
struct, in which the vid is stored in the structs' rbid
field.
rb_stts, the hw "write" pointer of rx is stored in a

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

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().

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
David Howells says:
====================
rxrpc: Development
Here are some patches that add some more tracepoints to AF_RXRPC and fix
some issues therein. The most significant points are:
(1) Display the call timeout information in /proc/net/rxrpc/calls.
(2) Save the call's debug_id in the rxrpc_channel struct so that it can be
used in traces after the rxrpc_call struct has been destroyed.
(3) Increase the size of the kAFS Rx window from 32 to 63 to be about the
same as the Auristor server.
(4) Propose the terminal ACK for a client call after it has received all
its data to be transmitted after a short interval so that it will get
transmitted if not first superseded by a new call on the same channel.
(5) Flush ACKs during the data reception if we detect that we've run out
of data.[*]
(6) Trace successful packet transmission and softirq to process context
socket notification.
[*] Note that on a uncontended gigabit network, rxrpc runs in to trouble
with ACK packets getting batched together (up to ~32 at a time)
somewhere between the IP transmit queue on the client and the ethernet
receive queue on the server.
I can see the kernel afs filesystem client and Auristor userspace
server stalling occasionally on a 512MB single read. Sticking
tracepoints in the network driver at either end seems to show that,
although the ACK transmissions made by the client are reasonably spaced
timewise, the received ACKs come in batches from the network card on
the server.
I'm not sure what, if anything, can be done about this.
