Stephane reported that perf report and annotate failed to process data
using lots of (> 500) shared libraries. It was because of the limit on
number of open files (ulimit -n).
Currently when perf loads a DSO, it'll look for normal and dynamic
symbol tables. And if it fails to find out both tables, it'll iterate
all of possible symtab types. But many of them are useless since they
have no additional information and the problem is that it's not closing
those files even though they're not used. Fix it.

The TUI of perf report and top support annotation, but stdio and GTK
don't. So it should be checked before calling hist_entry__inc_addr_
samples() to avoid wasting resources that will never be used.
perf annotate need it regardless of UI and sort keys, so the check
of whether to allocate resources should be on the tools that have
annotate as an option in the TUI, 'report' and 'top', not on the
function called by all of them.
It caused perf annotate on ppc64 to produce zero output, since the
buckets were not being allocated.

The DT bindings document a renesas,indices property, while the code, the
DT example and the DT sources all use renesas,clock-indices. Fix the
documentation.
The shmobile mstp DT bindings have been merged in v3.14-rc1 with a bug
in the DT ABI, a fix during the -rc series is appropriate.

The qspi clock divisor is incorrectly set to twice the value it should
have, possibly because it has been computed based on PLL1 as the clock
parent instead of PLL1 / 2 (the datasheets specifies the qspi nominal
frequencies, not the divisor values). Fix it.
This bug introduced in v3.14-rc1 breaks various devices on the Lager and
Kolesh shmobile boards and should thus be considered as a regression for
which a fix during the -rc series is appropriate.

The MLME code in mac80211 must track whether or not the AP changed
bandwidth, but if there's no change while tracking it shouldn't do
anything, otherwise regulatory updates can make it impossible to
connect to certain APs if the regulatory database doesn't match the
information from the AP. See the precise scenario described in the
code.
This still leaves some possible problems with CSA or if the AP
actually changed bandwidth, but those cases are less common and
won't completely prevent using it.

We had a bug discovered recently where an upper layer function
(cifs_iovec_write) could pass down a smb_rqst with an invalid amount of
data in it. The length of the SMB frame would be correct, but the rqst
struct would cause smb_send_rqst to send nearly 4GB of data.
This should never be the case. Add some sanity checking to the beginning
of smb_send_rqst that ensures that the amount of data we're going to
send agrees with the length in the RFC1002 header. If it doesn't, WARN()
and return -EIO to the upper layers.

This patch fixes a bug in sbc_dif_copy_prot() where the updated addr
offset did not take into account the case where the associated
scatterlist had not been incremented.
This addresses the case where incoming protection scatterlists may
contain a length smaller than PAGE_SIZE across multiple entires,
when the target protection scatterlists are always being explicitly
filled up to PAGE_SIZE before adding another entry.

1) In current implementation, ecclayout->oobfree->offset is calculated with
respect to ecclayout->eccpos[0] which is incorrect because ECC bytes may not
be stored contiguously in OOB.
So, this patch calculates ecclayout->oobfree->offset with respect to last
ECC byte-position 'eccpos[ecclayout->eccbytes-1]'.
2) ECC layout of some ecc-schemes expects reserved-markers at specific eccpos[]
which should not be over-written by any file-system metadata.
So this patch aligns oobfree->offset taking into account of such markers.

fix issues which will prevent correct operation in some use cases and
only affect that particular driver so are reasonably safe.

Pull xfs fixes from Dave Chinner:
"This is the first pull request I've had to do for you, so I'm still
sorting things out. The reason I'm sending this and not Ben should be
obvious from the first commit below - SGI has stepped down from the
XFS maintainership role. As such, I'd like to take another
opportunity to thank them for their many years of effort maintaining
XFS and supporting the XFS community that they developed from the
ground up.
So I haven't had time to work things like signed tags into my
workflows yet, so this is just a repo branch I'm asking you to pull
from. And yes, I named the branch -rc4 because I wanted the fixes in
rc4, not because the branch was for merging into -rc3. Probably not
right, either.
Anyway, I should have everything sorted out by the time the next merge
window comes around. If there's anything that you don't like in the
pull req, feel free to flame me unmercifully.
The changes are fixes for recent regressions and important thinkos in
verification code:
- a log vector buffer alignment issue on ia32
- timestamps on truncate got mangled
- primary superblock CRC validation fixes and error message
sanitisation"
* 'xfs-fixes-for-3.14-rc4' of git://oss.sgi.com/xfs/xfs:

Currently we generate a new fragmentation id on UFO segmentation. It
is pretty hairy to identify the correct net namespace and dst there.
Especially tunnels use IFF_XMIT_DST_RELEASE and thus have no skb_dst
available at all.
This causes unreliable or very predictable ipv6 fragmentation id
generation while segmentation.
Luckily we already have pregenerated the ip6_frag_id in
ip6_ufo_append_data and can use it here.

Problem statement: 1) both paths (primary path1 and alternate
path2) are up after the association has been established i.e.,
HB packets are normally exchanged, 2) path2 gets inactive after
path_max_retrans * max_rto timed out (i.e. path2 is down completely),
3) now, if a transmission times out on the only surviving/active
path1 (any ~1sec network service impact could cause this like
a channel bonding failover), then the retransmitted packets are
sent over the inactive path2; this happens with partial failover
and without it.
Besides not being optimal in the above scenario, a small failure
or timeout in the only existing path has the potential to cause
long delays in the retransmission (depending on RTO_MAX) until
the still active path is reselected. Further, when the T3-timeout
occurs, we have active_patch == retrans_path, and even though the
timeout occurred on the initial transmission of data, not a
retransmit, we end up updating retransmit path.
RFC4960, section 6.4. "Multi-Homed SCTP Endpoints" states under
6.4.1. "Failover from an Inactive Destination Address" the
following:
Some of the transport addresses of a multi-homed SCTP endpoint
may become inactive due to either the occurrence of certain
error conditions (see Section 8.2) or adjustments from the
SCTP user.
When there is outbound data to send and the primary path
becomes inactive (e.g., due to failures), or where the SCTP
user explicitly requests to send data to an inactive
destination transport address, before reporting an error to
its ULP, the SCTP endpoint should try to send the data to an
alternate __active__ destination transport address if one
exists.
When retransmitting data that timed out, if the endpoint is
multihomed, it should consider each source-destination address
pair in its retransmission selection policy. When retransmitting
timed-out data, the endpoint should attempt to pick the most
divergent source-destination pair from the original
source-destination pair to which the packet was transmitted.
Note: Rules for picking the most divergent source-destination
pair are an implementation decision and are not specified
within this document.
So, we should first reconsider to take the current active
retransmission transport if we cannot find an alternative
active one. If all of that fails, we can still round robin
through unkown, partial failover, and inactive ones in the
hope to find something still suitable.
Commit 4141ddc02a92 ("sctp: retran_path update bug fix") broke
that behaviour by selecting the next inactive transport when
no other active transport was found besides the current assoc's
peer.retran_path. Before commit 4141ddc02a92, we would have
traversed through the list until we reach our peer.retran_path
again, and in case that is still in state SCTP_ACTIVE, we would
take it and return. Only if that is not the case either, we
take the next inactive transport.
Besides all that, another issue is that transports in state
SCTP_UNKNOWN could be preferred over transports in state
SCTP_ACTIVE in case a SCTP_ACTIVE transport appears after
SCTP_UNKNOWN in the transport list yielding a weaker transport
state to be used in retransmission.
This patch mostly reverts 4141ddc02a92, but also rewrites
this function to introduce more clarity and strictness into
the code. A strict priority of transport states is enforced
in this patch, hence selection is active > unkown > partial
failover > inactive.

This patch fixes bug introduced by:
commit 1d4c8c29841b9991cdf3c7cc4ba7f96a94f104ca
"neigh: restore old behaviour of default parms values"
The thing is that in neigh_sysctl_register, extra1 and extra2 which were
previously set for NEIGH_VAR_GC_* are overwritten. That leads to
nonsense int limits for gc_* variables. So fix this by not touching
extra* fields for gc_* variables.

This patch fixes two bugs in fastopen :
1) The tcp_sendmsg(..., @size) argument was ignored.
Code was relying on user not fooling the kernel with iovec mismatches
2) When MTU is about 64KB, tcp_send_syn_data() attempts order-5
allocations, which are likely to fail when memory gets fragmented.

Ying Xue says:
====================
tipc: clean up components initialization code
In this series, we will fix a regression issue involved by commit
6e967adf7(tipc: relocate common functions from media to bearer)
But before the issue is fixed, we firstly adjust the process of
components initialization so as to remove all enabled flags from
necessary tipc components. Otherwise, without the change, we also
have to add an extra enabled flag into bearer layer indicating
whether bearer setup is finshed or not.

Accidentally a side effect is involved by commit 6e967adf7(tipc:
relocate common functions from media to bearer). Now tipc stack
handler of receiving packets from netdevices as well as netdevice
notification handler are registered when bearer is enabled rather
than tipc module initialization stage, but the two handlers are
both unregistered in tipc module exit phase. If tipc module is
inserted and then immediately removed, the following warning
message will appear:
"dev_remove_pack: ffffffffa0380940 not found"
This is because in module insertion stage tipc stack packet handler
is not registered at all, but in module exit phase dev_remove_pack()
needs to remove it. Of course, dev_remove_pack() cannot find tipc
protocol handler from the kernel protocol handler list so that the
warning message is printed out.
But if registering the two handlers is adjusted from enabling bearer
phase into inserting module stage, the warning message will be
eliminated. Due to this change, tipc_core_start_net() and
tipc_core_stop_net() can be deleted as well.

When tipc module is inserted, many tipc components are initialized
one by one. During the initialization period, if one of them is
failed, tipc_core_stop() will be called to stop all components
whatever corresponding components are created or not. To avoid to
release uncreated ones, relevant components have to add necessary
enabled flags indicating whether they are created or not.
But in the initialization stage, if one component is unsuccessfully
created, we will just destroy successfully created components before
the failed component instead of all components. All enabled flags
defined in components, in turn, become redundant. Additionally it's
also unnecessary to identify whether table.types is NULL in
tipc_nametbl_stop() because name stable has been definitely created
successfully when tipc_nametbl_stop() is called.
