The LTR is the handshake between the device and the root
complex about the latency allowed when the bus exits power
save. This configuration was missing and this led to high
latency in the link power up. The end user could experience
high latency in the network because of this.

Many AP devices do not have the proper regulatory domain programmed in
EEPROM. Instead they expect the software to set the appropriate region.
For these devices, the country code defaults to US, and the driver uses
the US CTL tables as well.
On devices bought in Europe this can lead to tx power being set too high
on the band edges, even if the cfg80211 regdomain is set correctly.
Fix this issue by taking into account the DFS region, but only when the
EEPROM regdomain is set to default.

Signed-off-by: David S. Miller <davem@davemloft.net>
Currently the amd-xgbe driver increments the packets processed counter
each time a descriptor is processed. Since a packet can be represented
by more than one descriptor incrementing the counter in this way is not
appropriate. Also, since multiple descriptors cause the budget check
to be short circuited, sometimes the returned value from the poll
function would be larger than the budget value resulting in a WARN_ONCE
being triggered.
Update the polling logic to properly account for the number of packets
processed and exit when the budget value is reached.

Since that feature is in the upper 32 bits of a 64 bit variable the

The commit "net: Save TX flow hash in sock and set in skbuf on xmit"
introduced the inet_set_txhash() and ip6_set_txhash() routines to calculate
and record flow hash(sk_txhash) in the socket structure. sk_txhash is used
to set skb->hash which is used to spread flows across multiple TXQs.
But, the above routines are invoked before the source port of the connection
is created. Because of this all outgoing connections that just differ in the
source port get hashed into the same TXQ.
This patch fixes this problem for IPv4/6 by invoking the the above routines
after the source port is available for the socket.

When a port that was used to listen for inbound connections gets closed
and reused for outgoing connections (like rsh ends up doing for stderr
flow), current we may reject the SYN/ACK packet for the new connection
because tcp_conntracks states forbirds a port to become a client while
there is still a TIME_WAIT entry in there for it.
As TCP may expire the TIME_WAIT socket in 60s and conntrack's timeout
for it is 120s, there is a ~60s window that the application can end up
opening a port that conntrack will end up blocking.
This patch fixes this by simply allowing such state transition: if we
see a SYN, in TIME_WAIT state, on REPLY direction, move it to sSS. Note
that the rest of the code already handles this situation, more
specificly in tcp_packet(), first switch clause.

net: minor gso encapsulation fixes
The following series fixes a minor bug in the gso segmentation handlers
when encapsulation offload is used.
Theoretically this could cause kernel panic when the stack tries
to software-segment such a GRE offload packet, but it looks like there
is only one affected call site (tbf scheduler) and it handles NULL
return value.
I've included a followup patch to add IS_ERR_OR_NULL checks where needed.
While looking into this, I also found that size computation of the individual
segments is incorrect if skb->encapsulation is set.
Please see individual patches for delta vs. v1.

if ->encapsulation is set we have to use inner_tcp_hdrlen and add the

skb_gso_segment has three possible return values:
1. a pointer to the first segmented skb
2. an errno value (IS_ERR())
3. NULL. This can happen when GSO is used for header verification.
However, several callers currently test IS_ERR instead of IS_ERR_OR_NULL
and would oops when NULL is returned.
Note that these call sites should never actually see such a NULL return
value; all callers mask out the GSO bits in the feature argument.
However, there have been issues with some protocol handlers erronously not
respecting the specified feature mask in some cases.
It is preferable to get 'have to turn off hw offloading, else slow' reports
rather than 'kernel crashes'.
Signed-off-by: Florian Westphal <fw@strlen.de>
Signed-off-by: David S. Miller <davem@davemloft.net>
skb_gso_segment() has a 'features' argument representing offload features
available to the output path.
A few handlers, e.g. GRE, instead re-fetch the features of skb->dev and use
those instead of the provided ones when handing encapsulation/tunnels.
Depending on dev->hw_enc_features of the output device skb_gso_segment() can
then return NULL even when the caller has disabled all GSO feature bits,
as segmentation of inner header thinks device will take care of segmentation.
This e.g. affects the tbf scheduler, which will silently drop GRE-encap GSO skbs
that did not fit the remaining token quota as the segmentation does not work
when device supports corresponding hw offload capabilities.

The following patch fixes a bug which causes the ax88179_178a driver to be
incapable of being added to a bond.
When I brought up the issue with the bonding maintainers, they indicated
that the real problem was with the NIC driver which must return zero for
success (of setting the MAC address). I see that several other NIC drivers
follow that pattern by either simply always returing zero, or by passing
through a negative (error) result while rewriting any positive return code
to zero. With that same philisophy applied to the ax88179_178a driver, it
allows it to work correctly with the bonding driver.
I believe this is suitable for queuing in -stable, as it's a small, simple,
and obvious fix that corrects a defect with no other known workaround.
This patch is against vanilla 3.17(.0).

Here are a collection of small fixes after 3.18 merge. The urgent
one is the fix for kernel panics with linked PCM substream triggered
by the recent nonatomic PCM ops support. Other two fixes (emu10k1 and
bebob) are stable fixes, and one easy PCI ID addition for a new Intel
HD-audio controller.

Pull more perf updates from Ingo Molnar:
"A second (and last) round of late coming fixes and changes, almost all
of them in perf tooling:
User visible tooling changes:
- Add period data column and make it default in 'perf script' (Jiri
Olsa)
- Add a visual cue for toggle zeroing of samples in 'perf top'
(Taeung Song)
- Improve callchains when using libunwind (Namhyung Kim)
Tooling fixes and infrastructure changes:
- Fix for double free in 'perf stat' when using some specific invalid
command line combo (Yasser Shalabi)
- Fix off-by-one bugs in map->end handling (Stephane Eranian)
- Fix off-by-one bug in maps__find(), also related to map->end
handling (Namhyung Kim)
- Make struct symbol->end be the first addr after the symbol range,
to make it match the convention used for struct map->end. (Arnaldo
Carvalho de Melo)
- Fix perf_evlist__add_pollfd() error handling in 'perf kvm stat
live' (Jiri Olsa)
- Fix python test build by moving callchain_param to an object linked
into the python binding (Jiri Olsa)
- Document sysfs events/ interfaces (Cody P Schafer)
- Fix typos in perf/Documentation (Masanari Iida)
- Add missing 'struct option' forward declaration (Arnaldo Carvalho
de Melo)
- Add option to copy events when queuing for sorting across cpu
buffers and enable it for 'perf kvm stat live', to avoid having
events left in the queue pointing to the ring buffer be rewritten
in high volume sessions. (Alexander Yarygin, improving work done
by David Ahern):
- Do not include a struct hists per perf_evsel, untangling the
histogram code from perf_evsel, to pave the way for exporting a
minimalistic tools/lib/api/perf/ library usable by tools/perf and
initially by the rasd daemon being developed by Borislav Petkov,
Robert Richter and Jean Pihet. (Arnaldo Carvalho de Melo)
- Make perf_evlist__open(evlist, NULL, NULL), i.e. without cpu and
thread maps mean syswide monitoring, reducing the boilerplate for
tools that only want system wide mode. (Arnaldo Carvalho de Melo)
- Move exit stuff from perf_evsel__delete to perf_evsel__exit, delete
should be just a front end for exit + free (Arnaldo Carvalho de
Melo)
- Add support to new style format of kernel PMU event. (Kan Liang)
and other misc fixes"

Pull sparc fixes from David Miller:
"Here we have two bug fixes:
1) The current thread's fault_code is not setup properly upon entry to

2) Don't use a zero length array at the end of thread_info on sparc64,
otherwise end_of_stack() isn't right"

"A quick batch of bug fixes:
1) Fix build with IPV6 disabled, from Eric Dumazet.
2) Several more cases of caching SKB data pointers across calls to
pskb_may_pull(), thus referencing potentially free'd memory. From
Li RongQing.
3) DSA phy code tests operation presence improperly, instead of going:
