virtio-pci: make reset operation safer
virtio pci device reset actually just does an I/O
write, which in PCI is really posted, that is it
can complete on CPU before the device has received it.
Further, interrupts might have been pending on
another CPU, so device callback might get invoked after reset.
This conflicts with how drivers use reset, which is typically:
reset
unregister
a callback running after reset completed can race with
unregister, potentially leading to use after free bugs.
Fix by flushing out the write, and flushing pending interrupts.
This assumes that device is never reset from
its vq/config callbacks, or in parallel with being
added/removed, document this assumption.

Tyler Hicks [Wed, 23 Nov 2011 17:31:24 +0000 (11:31 -0600)]
eCryptfs: Extend array bounds for all filename chars
From mhalcrow's original commit message:
Characters with ASCII values greater than the size of
filename_rev_map[] are valid filename characters.
ecryptfs_decode_from_filename() will access kernel memory beyond
that array, and ecryptfs_parse_tag_70_packet() will then decrypt
those characters. The attacker, using the FNEK of the crafted file,
can then re-encrypt the characters to reveal the kernel memory past
the end of the filename_rev_map[] array. I expect low security
impact since this array is statically allocated in the text area,
and the amount of memory past the array that is accessible is
limited by the largest possible ASCII filename character.
This patch solves the issue reported by mhalcrow but with an
implementation suggested by Linus to simply extend the length of
filename_rev_map[] to 256. Characters greater than 0x7A are mapped to
0x00, which is how invalid characters less than 0x7A were previously
being handled.

As requested by Ben Herrenschmidt:
"This breaks some powerpc platforms at least. The practice of having
a node provide an explicit "interrupt-parent" property pointing to
itself is an old trick that we've used in the past to allow a
device-node to have interrupts routed to different controllers.
In that case, the node also contains an interrupt-map, so the node is
its own parent, the interrupt resolution hits the map, which then can
route each individual interrupt to a different parent."
Grant says:
"Ah, nuts, yes that is broken then. Yes, please revert the commit and
Rob & I will come up with a better solution.
Rob, I think it can be done by explicitly checking for np ==

SUNRPC: Ensure we return EAGAIN in xs_nospace if congestion is cleared
By returning '0' instead of 'EAGAIN' when the tests in xs_nospace() fail
to find evidence of socket congestion, we are making the RPC engine believe
that the message was incorrectly sent and so it disconnects the socket
instead of just retrying.
The bug appears to have been introduced by commit
5e3771ce2d6a69e10fcc870cdf226d121d868491 (SUNRPC: Ensure that xs_nospace
return values are propagated).

percpu: fix chunk range calculation
Percpu allocator recorded the cpus which map to the first and last
units in pcpu_first/last_unit_cpu respectively and used them to
determine the address range of a chunk - e.g. it assumed that the
first unit has the lowest address in a chunk while the last unit has
the highest address.
This simply isn't true. Groups in a chunk can have arbitrary positive
or negative offsets from the previous one and there is no guarantee
that the first unit occupies the lowest offset while the last one the
highest.
Fix it by actually comparing unit offsets to determine cpus occupying
the lowest and highest offsets. Also, rename pcu_first/last_unit_cpu
to pcpu_low/high_unit_cpu to avoid confusion.
The chunk address range is used to flush cache on vmalloc area
map/unmap and decide whether a given address is in the first chunk by
per_cpu_ptr_to_phys() and the bug was discovered by invalid
per_cpu_ptr_to_phys() translation for crash_note.

Btrfs: remove free-space-cache.c WARN during log replay
The log replay code only partially loads block groups, since
the block group caching code is able to detect and deal with
extents the logging code has pinned down.
While the logging code is pinning down block groups, there is
a bogus WARN_ON we're hitting if the code wasn't able to find
an extent in the cache. This commit removes the warning because
it can happen any time there isn't a valid free space cache
for that block group.

Commit
99d1717d (ARM: Add init_consistent_dma_size()) introduces dynamic

calculated based on the number of PMD entries rather than PGD, hence the
PMD_SHIFT.

ARM: 7162/1: errata: tidy up Kconfig options for PL310 errata workarounds
The Kconfig options for the PL310 errata workarounds do not use a
consistent naming scheme for either the config option or the bool
description.
This patch tidies up the options by ensuring that the bool descriptions
are prefixed with "PL310 errata:" and the config options are prefixed
with PL310_ERRATA_, making it much clearer in menuconfig as to what the
workarounds are for.

ARM: 7161/1: errata: no automatic store buffer drain
This patch implements a workaround for PL310 erratum 769419. On
revisions of the PL310 prior to r3p2, the Store Buffer does not
automatically drain. This can cause normal, non-cacheable writes to be
retained when the memory system is idle, leading to suboptimal I/O
performance for drivers using coherent DMA.
This patch adds an optional wmb() call to the cpu_idle loop. On systems
with an outer cache, this causes an explicit flush of the store buffer.

VFS: Log the fact that we've given ELOOP rather than creating a loop
To prevent an NFS server from being used to create a directory loop in an NFS
superblock on the client, the following patch was committed:
commit
1836750115f20b774e55c032a3893e8c5bdf41ed
Author: Al Viro <viro@zeniv.linux.org.uk>
Date: Tue Jul 12 21:42:24 2011 -0400
Subject: fix loop checks in d_materialise_unique()
This causes ELOOP to be reported to anyone trying to access the dentry that
would otherwise cause the kernel to complete the loop.
However, no indication is given to the caller as to why an operation that ought
to work doesn't. The fault is with the kernel, which doesn't want to try and
solve the problem as it gets horrendously messy if there's another mountpoint
somewhere in the trees being spliced that can't be moved[*].
[*] The real problem is that we don't handle the excision of a subtree that
gets moved _out_ of what we can see. This can happen on the server where a
directory is merely moved between two other dirs on the same filesystem, but
where destination dir is not accessible by the client.
So, given the choice to return ELOOP rather than trying to reconfigure the
dentry tree, we should give the caller some indication of why they aren't being
allowed to make what should be a legitimate request and log a message.
