cxgb4/iw_cxgb4: Doorbell Drop Avoidance Bug Fixes
The current logic suffers from a slow response time to disable user DB
usage, and also fails to avoid DB FIFO drops under heavy load. This commit
fixes these deficiencies and makes the avoidance logic more optimal.
This is done by more efficiently notifying the ULDs of potential DB
problems, and implements a smoother flow control algorithm in iw_cxgb4,
which is the ULD that puts the most load on the DB fifo.
Design:
cxgb4:
Direct ULD callback from the DB FULL/DROP interrupt handler. This allows
the ULD to stop doing user DB writes as quickly as possible.
While user DB usage is disabled, the LLD will accumulate DB write events
for its queues. Then once DB usage is reenabled, a single DB write is
done for each queue with its accumulated write count. This reduces the
load put on the DB fifo when reenabling.
iw_cxgb4:
Instead of marking each qp to indicate DB writes are disabled, we create
a device-global status page that each user process maps. This allows
iw_cxgb4 to only set this single bit to disable all DB writes for all
user QPs vs traversing the idr of all the active QPs. If the libcxgb4
doesn't support this, then we fall back to the old approach of marking
each QP. Thus we allow the new driver to work with an older libcxgb4.
When the LLD upcalls iw_cxgb4 indicating DB FULL, we disable all DB writes
via the status page and transition the DB state to STOPPED. As user
processes see that DB writes are disabled, they call into iw_cxgb4
to submit their DB write events. Since the DB state is in STOPPED,
the QP trying to write gets enqueued on a new DB "flow control" list.
As subsequent DB writes are submitted for this flow controlled QP, the
amount of writes are accumulated for each QP on the flow control list.
So all the user QPs that are actively ringing the DB get put on this
list and the number of writes they request are accumulated.
When the LLD upcalls iw_cxgb4 indicating DB EMPTY, which is in a workq
context, we change the DB state to FLOW_CONTROL, and begin resuming all
the QPs that are on the flow control list. This logic runs on until
the flow control list is empty or we exit FLOW_CONTROL mode (due to
a DB DROP upcall, for example). QPs are removed from this list, and
their accumulated DB write counts written to the DB FIFO. Sets of QPs,
called chunks in the code, are removed at one time. The chunk size is 64.
So 64 QPs are resumed at a time, and before the next chunk is resumed, the
logic waits (blocks) for the DB FIFO to drain. This prevents resuming to
quickly and overflowing the FIFO. Once the flow control list is empty,
the db state transitions back to NORMAL and user QPs are again allowed
to write directly to the user DB register.
The algorithm is designed such that if the DB write load is high enough,
then all the DB writes get submitted by the kernel using this flow
controlled approach to avoid DB drops. As the load lightens though, we
resume to normal DB writes directly by user applications.

"Three of these are regression fixes, for two recent regressions and
one introduced during the 3.13 cycle, and the fourth one is a working
version of the fix that had to be reverted last time.
Specifics:
- A recent ACPI resources handling fix overlooked the fact that it
had to update the ACPI PNP subsystem's resources parsing too and
caused confusing warning messages to be printed during system
intialization on some systems (with arguably buggy ACPI tables).
Fix from Zhang Rui.
- Moving the early ACPI initialization before timekeeping_init()
earlier in this cycle broke fast TSC calibration on at least one
system, so it needs to be done later, but still before
efi_enter_virtual_mode() to allow the EFI initialization to refer
to ACPI.
- A change related to code duplication reduction in the cpufreq core
inadvertently caused cpufreq intialization to fail for some CPUs
handled by intel_pstate by adding checks that may fail for that
driver, but aren't even necessary when it is used. The issue is
addressed by preventing those checks from run in the configurations
in which they aren't needed.
- If the Hardware Reduced ACPI flag is set in the ACPI tables, system
suspend, hibernation and ACPI power off will only work when special
sleep control and sleep status registeres are provided (their
addresses in the ACPI tables are not zero). If those registers are
not available, the features in question have no chances to work, so
they shouldn't even be regarded as supported. That helps with
power off in particular, because alternative power off methods may
be used then and they may actually work"

wireless folks under no uncertain terms that they must severely scale

Anyways:
1) vmxnet3's netpoll doesn't perform the equivalent of an ISR, which
is the correct implementation, like it should. Instead it does
something like a NAPI poll operation. This leads to crashes.
From Neil Horman and Arnd Bergmann.
2) Segmentation of SKBs requires proper socket orphaning of the
fragments, otherwise we might access stale state released by the
release callbacks.
This is a 5 patch fix, but the initial patches are giving
variables and such significantly clearer names such that the
actual fix itself at the end looks trivial.
From Michael S. Tsirkin.
3) TCP control block release can deadlock if invoked from a timer on
an already "owned" socket. Fix from Eric Dumazet.
4) In the bridge multicast code, we must validate that the
destination address of general queries is the link local all-nodes
multicast address. From Linus Lüssing.
5) The x86 BPF JIT support for negative offsets puts the parameter
for the helper function call in the wrong register. Fix from
Alexei Starovoitov.
6) The descriptor type used for RTL_GIGA_MAC_VER_17 chips in the
r8169 driver is incorrect. Fix from Hayes Wang.
7) The xen-netback driver tests skb_shinfo(skb)->gso_type bits to see
if a packet is a GSO frame, but that's not the correct test. It
should use skb_is_gso(skb) instead. Fix from Wei Liu.
8) Negative msg->msg_namelen values should generate an error, from
Matthew Leach.
9) at86rf230 can deadlock because it takes the same lock from it's
ISR and it's hard_start_xmit method, without disabling interrupts
in the latter. Fix from Alexander Aring.
10) The FEC driver's restart doesn't perform operations in the correct
order, so promiscuous settings can get lost. Fix from Stefan
Wahren.
11) Fix SKB leak in SCTP cookie handling, from Daniel Borkmann.
12) Reference count and memory leak fixes in TIPC from Ying Xue and
Erik Hugne.
13) Forced eviction in inet_frag_evictor() must strictly make sure all
frags are deleted, otherwise module unload (f.e. 6lowpan) can
crash. Fix from Florian Westphal.
14) Remove assumptions in AF_UNIX's use of csum_partial() (which it
uses as a hash function), which breaks on PowerPC. From Anton
Blanchard.
The main gist of the issue is that csum_partial() is defined only
as a value that, once folded (f.e. via csum_fold()) produces a
correct 16-bit checksum. It is legitimate, therefore, for
csum_partial() to produce two different 32-bit values over the
same data if their respective alignments are different.
15) Fix endiannes bug in MAC address handling of ibmveth driver, also
from Anton Blanchard.
16) Error checks for ipv6 exthdrs offload registration are reversed,
from Anton Nayshtut.
17) Externally triggered ipv6 addrconf routes should count against the
garbage collection threshold. Fix from Sabrina Dubroca.
18) The PCI shutdown handler added to the bnx2 driver can wedge the
chip if it was not brought up earlier already, which in particular
causes the firmware to shut down the PHY. Fix from Michael Chan.
19) Adjust the sanity WARN_ON_ONCE() in qdisc_list_add() because as
currently coded it can and does trigger in legitimate situations.
From Eric Dumazet.
20) BNA driver fails to build on ARM because of a too large udelay()
call, fix from Ben Hutchings.
21) Fair-Queue qdisc holds locks during GFP_KERNEL allocations, fix

regression in source MAC address setting of outgoing headers in
some circumstances. Fix from Peter Boström"

ACPI / sleep: Add extra checks for HW Reduced ACPI mode sleep states
If the HW Reduced ACPI mode bit is set in the FADT, ACPICA uses
the optional sleep control and sleep status registers for making
the system enter sleep states (including S5), so it is not possible
to use system sleep states or power it off using ACPI if the HW
Reduced ACPI mode bit is set and those registers are not available.
For this reason, add a new function, acpi_sleep_state_supported(),
checking if the HW Reduced ACPI mode bit is set and whether or not
system sleep states are usable in that case in addition to checking
the return value of acpi_get_sleep_type_data() and make the ACPI
sleep setup routines use that function to check the availability of
system sleep states.
Among other things, this prevents the kernel from attempting to
use ACPI for powering off HW Reduced ACPI systems without the sleep
control and sleep status registers, because ACPI power off doesn't
have a chance to work on them. That allows alternative power off
mechanisms that may actually work to be used on those systems. The
affected machines include Dell Venue 8 Pro, Asus T100TA, Haswell
Desktop SDP and Ivy Bridge EP Demo depot.

one by myself to add NAPI support back to mac80211, which can help
improve TCP behaviour through GRO."
For the Bluetooth bits, Gustavo says:
"This is our first pull request for 3.15, the main feature here is the addition of
the privacy feature for low energy devices. Other than that we have a bunch of small
improvements, fixes, and clean ups all over the tree."
And...
"Another pull request to 3.15. Here we have the second part of the LE private
feature, the LE auto-connect feature and improvements to the power off
procedures. The rest are small improvements, clean up, and fixes."
For the iwlwifi bits, Emmanuel says:
"I have here a whole bunch of various things. Trivial cleanups,
debugfs handlers and new stuff for the new generation of devices
along with new capabilities for monitor mode. We also have support
for power save for dual interface mode, but that is not supported by
the firmware currently available."
And for the Atheros bits, Kalle says:
"For ath10k Alexander did some cleanup to PCI error cases and switched
ath10k to use pci_enable_msi_range(). Michal implemented AP CSA support
and sta_rc_update() operation. I enabled firmware "STA quick kickout"
functionality for faster detection of disappeared clients.
Also there are lots of small fixes to everywhere from various people."
I pulled the wireless tree to avoid some merge conflicts, and I
reverted the staging patch that I had mistakenly merged previously.
Along with that, mwifiex, brcmfmac, wil6210, ath9k, and a few other
drivers get their usual round of updates. Also notable is the addition
of yet another driver in the rtlwifi family.
...
I have amended this commit request to correct the build problems in
staging, including a warning added to one of the staging drivers by
the wireless-next tree. I also included a fix from Larry Finger to
address an issue found in rtl8723be by Dan Carpenter and smatch.

net: sctp: remove NULL check in sctp_assoc_update_retran_path
This is basically just to let Coverity et al shut up. Remove an
unneeded NULL check in sctp_assoc_update_retran_path().
It is safe to remove it, because in sctp_assoc_update_retran_path()
we iterate over the list of transports, our own transport which is
asoc->peer.retran_path included. In the iteration, we skip the
list head element and transports in state SCTP_UNCONFIRMED.
Such transports came from peer addresses received in INIT/INIT-ACK
address parameters. They are not yet confirmed by a heartbeat and
not available for data transfers.
We know however that in the list of transports, even if it contains
such elements, it at least contains our asoc->peer.retran_path as
well, so even if next to that element, we only encounter
SCTP_UNCONFIRMED transports, we are always going to fall back to
asoc->peer.retran_path through sctp_trans_elect_best(), as that is
for sure not SCTP_UNCONFIRMED as per
fbdf501c9374 ("sctp: Do no
select unconfirmed transports for retransmissions").
Whenever we call sctp_trans_elect_best() it will give us a non-NULL
element back, and therefore when we break out of the loop, we are
guaranteed to have a non-NULL transport pointer, and can remove
the NULL check.

cpufreq: Skip current frequency initialization for ->setpolicy drivers
After commit
da60ce9f2fac (cpufreq: call cpufreq_driver->get() after
calling ->init()) __cpufreq_add_dev() sometimes fails for CPUs handled
by intel_pstate, because that driver may return 0 from its ->get()
callback if it has not run long enough to collect enough samples on the
given CPU. That didn't happen before commit
da60ce9f2fac which added
policy->cur initialization to __cpufreq_add_dev() to help reduce code
duplication in other cpufreq drivers.
However, the code added by commit
da60ce9f2fac need not be executed
for cpufreq drivers having the ->setpolicy callback defined, because
the subsequent invocation of cpufreq_set_policy() will use that
callback to initialize the policy anyway and it doesn't need
policy->cur to be initialized upfront. The analogous code in
cpufreq_update_policy() is also unnecessary for cpufreq drivers
having ->setpolicy set and may be skipped for them as well.
Since intel_pstate provides ->setpolicy, skipping the upfront
policy->cur initialization for cpufreq drivers with that callback
set will cover intel_pstate and the problem it's been having after
commit
da60ce9f2fac will be addressed.
