WCN3990 is integrated 802.11ac chipset with SNOC
bus interface. Add snoc layer driver registration
and associated ops.
WCN3990 support is not yet complete as cold-boot
handshake is done using qmi(Qualcomm-MSM-Interface)
and qmi client support will be added once qmi framework
is available.

CE layer is shared between pci and snoc target and results
in duplicate object inclusion if both modules are compiled
together statically and undefined KBUILD_MODNAME if
compiled as module.
Fix this by building ce layer in ath10k core module by
adding ce object inclusion with ATH10K_CE boolean CONFIG.

GFP_ATOMIC should only be used when the allocation is done from atomic
context. Introduce a new flag to wcn36xx_dxe_fill_skb() and use GFP_KERNEL
when pre-allocating buffers during init.
This doesn't fix an issue that was observed in the wild, but it reduces
the chance of failed allocations under memory pressure.

The firmware code cannot cope with requests to remove BSS indices that have
not previously been added. This primarily happens when the device is
suspended and then resumed. ieee80211_reconfig() then calls into
wcn36xx_bss_info_changed() with an empty bssid and BSS_CHANGED_BSSID set,
which subsequently leads to a firmware crash:
[ 43.647928] qcom-wcnss-pil a204000.wcnss: fatal error received: halMsg.c:4964:halMsg_DelBss: Invalid BSSIndex 0
[ 43.647959] remoteproc remoteproc0: crash detected in a204000.wcnss: type fatal error
To fix this, set bss_index to WCN36XX_HAL_BSS_INVALID_IDX for all bss
that have not been configured in the firmware, and don't call into the
firmware with invalid indices.

When wcn36xx_dxe_tx_frame() fails to transmit the TX frame, the driver
will call into ieee80211_free_txskb() for the skb in flight, so it'll no
longer be valid. Hence, we shouldn't keep a reference to it in ctl->skb.
Also, if the skb has IEEE80211_TX_CTL_REQ_TX_STATUS set, a pointer to
it will currently remain in wcn->tx_ack_skb, which will potentially lead
to a crash if accessed later.
Fix this by checking the return value of wcn36xx_dxe_tx_frame(), and
nullify wcn->tx_ack_skb again in case of errors. Move the assignment
of ctl->skb in wcn36xx_dxe_tx_frame() so it only happens when the
transmission is successful.

In preparation to enabling -Wvla, remove accidental use of stack VLA.
This avoids an accidental stack VLA (since the compiler thinks
the value of FFT_NUM_SAMPLES can change, even when marked
"const"). This just replaces it with a #define.

The way that 'strncat' is used here raised a warning in gcc-8:
drivers/net/wireless/ath/ath10k/wmi.c: In function 'ath10k_wmi_tpc_stats_final_disp_tables':
drivers/net/wireless/ath/ath10k/wmi.c:4649:4: error: 'strncat' output truncated before terminating nul copying as many bytes from a string as its length [-Werror=stringop-truncation]
Effectively, this is simply a strcat() but the use of strncat() suggests
some form of overflow check. Regardless of whether this might actually
overflow, using strlcat() instead of strncat() avoids the warning and
makes the code more robust.

Currently <linux/slab.h> #includes <linux/kmemleak.h> for no obvious
reason. It looks like it's only a convenience, so remove kmemleak.h
from slab.h and add <linux/kmemleak.h> to any users of kmemleak_* that
don't already #include it. Also remove <linux/kmemleak.h> from source
files that do not use it.
This is tested on i386 allmodconfig and x86_64 allmodconfig. It would
be good to run it through the 0day bot for other $ARCHes. I have
neither the horsepower nor the storage space for the other $ARCHes.
Update: This patch has been extensively build-tested by both the 0day
bot & kisskb/ozlabs build farms. Both of them reported 2 build failures
for which patches are included here (in v2).
[ slab.h is the second most used header file after module.h; kernel.h is
right there with slab.h. There could be some minor error in the
counting due to some #includes having comments after them and I didn't
combine all of those. ]

Pul removal of obsolete architecture ports from Arnd Bergmann:
"This removes the entire architecture code for blackfin, cris, frv,
m32r, metag, mn10300, score, and tile, including the associated device
drivers.
I have been working with the (former) maintainers for each one to
ensure that my interpretation was right and the code is definitely
unused in mainline kernels. Many had fond memories of working on the
respective ports to start with and getting them included in upstream,
but also saw no point in keeping the port alive without any users.
In the end, it seems that while the eight architectures are extremely
different, they all suffered the same fate: There was one company in
charge of an SoC line, a CPU microarchitecture and a software
ecosystem, which was more costly than licensing newer off-the-shelf
CPU cores from a third party (typically ARM, MIPS, or RISC-V). It
seems that all the SoC product lines are still around, but have not
used the custom CPU architectures for several years at this point. In
contrast, CPU instruction sets that remain popular and have actively
maintained kernel ports tend to all be used across multiple licensees.
[ See the new nds32 port merged in the previous commit for the next
generation of "one company in charge of an SoC line, a CPU
microarchitecture and a software ecosystem" - Linus ]
The removal came out of a discussion that is now documented at
https://lwn.net/Articles/748074/. Unlike the original plans, I'm not
marking any ports as deprecated but remove them all at once after I
made sure that they are all unused. Some architectures (notably tile,
mn10300, and blackfin) are still being shipped in products with old
kernels, but those products will never be updated to newer kernel
releases.
After this series, we still have a few architectures without mainline
gcc support:
- unicore32 and hexagon both have very outdated gcc releases, but the
maintainers promised to work on providing something newer. At least
in case of hexagon, this will only be llvm, not gcc.
- openrisc, risc-v and nds32 are still in the process of finishing
their support or getting it added to mainline gcc in the first
place. They all have patched gcc-7.3 ports that work to some
degree, but complete upstream support won't happen before gcc-8.1.
Csky posted their first kernel patch set last week, their situation
will be similar
[ Palmer Dabbelt points out that RISC-V support is in mainline gcc
since gcc-7, although gcc-7.3.0 is the recommended minimum - Linus ]"

Daniel Borkmann says:
====================
pull-request: bpf-next 2018-03-31
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add raw BPF tracepoint API in order to have a BPF program type that
can access kernel internal arguments of the tracepoints in their
raw form similar to kprobes based BPF programs. This infrastructure
also adds a new BPF_RAW_TRACEPOINT_OPEN command to BPF syscall which
returns an anon-inode backed fd for the tracepoint object that allows
for automatic detach of the BPF program resp. unregistering of the
tracepoint probe on fd release, from Alexei.
2) Add new BPF cgroup hooks at bind() and connect() entry in order to
allow BPF programs to reject, inspect or modify user space passed
struct sockaddr, and as well a hook at post bind time once the port
has been allocated. They are used in FB's container management engine
for implementing policy, replacing fragile LD_PRELOAD wrapper
intercepting bind() and connect() calls that only works in limited
scenarios like glibc based apps but not for other runtimes in
containerized applications, from Andrey.
3) BPF_F_INGRESS flag support has been added to sockmap programs for
their redirect helper call bringing it in line with cls_bpf based
programs. Support is added for both variants of sockmap programs,
meaning for tx ULP hooks as well as recv skb hooks, from John.
4) Various improvements on BPF side for the nfp driver, besides others
this work adds BPF map update and delete helper call support from
the datapath, JITing of 32 and 64 bit XADD instructions as well as
offload support of bpf_get_prandom_u32() call. Initial implementation
of nfp packet cache has been tackled that optimizes memory access
(see merge commit for further details), from Jakub and Jiong.
5) Removal of struct bpf_verifier_env argument from the print_bpf_insn()
API has been done in order to prepare to use print_bpf_insn() soon
out of perf tool directly. This makes the print_bpf_insn() API more
generic and pushes the env into private data. bpftool is adjusted
as well with the print_bpf_insn() argument removal, from Jiri.
6) Couple of cleanups and prep work for the upcoming BTF (BPF Type
Format). The latter will reuse the current BPF verifier log as
well, thus bpf_verifier_log() is further generalized, from Martin.
7) For bpf_getsockopt() and bpf_setsockopt() helpers, IPv4 IP_TOS read
and write support has been added in similar fashion to existing
IPv6 IPV6_TCLASS socket option we already have, from Nikita.
8) Fixes in recent sockmap scatterlist API usage, which did not use
sg_init_table() for initialization thus triggering a BUG_ON() in
scatterlist API when CONFIG_DEBUG_SG was enabled. This adds and
uses a small helper sg_init_marker() to properly handle the affected
cases, from Prashant.
9) Let the BPF core follow IDR code convention and therefore use the
idr_preload() and idr_preload_end() helpers, which would also help
idr_alloc_cyclic() under GFP_ATOMIC to better succeed under memory
pressure, from Shaohua.
10) Last but not least, a spelling fix in an error message for the
BPF cookie UID helper under BPF sample code, from Colin.

first bullet here:
* EAPoL-over-nl80211 from Denis - this will let us fix
some long-standing issues with bridging, races with
encryption and more
* DFS offload support from the qtnfmac folks
* regulatory database changes for the new ETSI adaptivity
requirements
* various other fixes and small enhancements
====================

Currently vdev stats displayed in fw_stats are applicable
only for TLV based firmware and fix it for 10.4 firmware
as of now. The vdev stats in 10.4 firmware is split into two
parts (vdev_stats, vdev_stats_extended). The actual stats
are captured only in extended vdev stats. In order to enable
vdev stats, appropriate feature bit will be set on extended
resource config. As FTM related counters are available only on
newer 10.4 based firmware, these counters will be displayed
only on valid data.

The commit "cfg80211: make RATE_INFO_BW_20 the default" changed
the index of RATE_INFO_BW_20, but the updates to ath10k missed
the special bandwidth calculation case in
ath10k_update_per_peer_tx_stats().
This will fix below warning,

This patch fixes regression caused by 0c317a02ca98
("cfg80211: support virtual interfaces with different beacon intervals"),
with this change cfg80211 expects the driver to advertize
'beacon_int_min_gcd' to support different beacon intervals in multivap
scenario. This support is added for, QCA988X/QCA99X0/QCA9984/QCA4019.
Verifed AP + mesh bring up on QCA9984 with beacon interval 100msec and
1000msec respectively.

TDLS is 3-way handshake host need send authorize cmd to firmware to unblock

In case wcn36xx_smd_rsp_process() is called more than once before
hal_ind_work was dispatched, the messages will end up in hal_ind_queue,
but wcn36xx_ind_smd_work() will only look at the first message in that
list.
Fix this by dequeing the messages from the list in a loop, and only stop
when it's empty.
This issue was found during a review of the driver. In my tests, that
race never actually occured.

wcn36xx_start_tx function retrieves the buffer descriptor from the
channel control queue to start filling tx buffer information. However,
nothing prevents this same buffer to be concurrently accessed in a
concurent tx call, leading to potential buffer coruption and firmware
crash (observed during iperf test). The channel control queue should
only be accessed and updated with the channel lock.
Fix this issue by using a local buffer descriptor which will be copied
in the thread-safe wcn36xx_dxe_tx_frame.
Note that buffer descriptor size is few bytes so the introduced copy
overhead is insignificant. Moreover, this allows to keep the locked
section minimal.

FW has Smart Logging feature enabled by default for detecting failures
and processing FATAL_CONDITION_EVENTID (36925 - 0x903D) back to host.
Since ath10k doesn't implement the Smart Logging and FATAL CONDITION
EVENT processing yet, suppressing the unknown event ID warning by moving
this under ATH10K_DBG_WMI.
Simulated the same issue by having associated STA powered off when
ping flood was running from AP backbone. This triggerd STA KICKOUT
in AP followed by FATAL CONDITION event 36925.
Issue was reproduced and verified in below DUT

it to be able to handle the get_temperature command and process the event.
You can read the temperature by using the hwmon interface,
cat /sys/class/ieee80211/phy*/device/hwmon/hwmon2/temp1_input
Verified with the following hardware and software combination,
QCA6174, only firmware-4.bin doesn't support this, otherwise all support.

This reverts commit 55884c045d31a29cf69db8332d1064a1b61dd159.
When Ath10k is in AP mode and an unassociated STA sends a VHT action frame
(Operating Mode Notification for the NSS change) periodically to AP this causes
ath10k to call ath10k_station_assoc() which sends WMI_PEER_ASSOC_CMDID during
NSS update. Over the time (with a certain client it can happen within 15 mins
when there are over 500 of these VHT action frames) continuous calls of
WMI_PEER_ASSOC_CMDID cause firmware to assert due to resource exhaust.
To my knowledge setting WMI_PEER_NSS peer param itself enough to handle NSS
updates and no need to call ath10k_station_assoc(). So revert the original
commit from 2014 as it's unclear why the change was really needed.
Now the firmware assert doesn't happen anymore.
Issue observed in QCA9984 platform with firmware version:10.4-3.5.3-00053.
This Change tested in QCA9984 with firmware version: 10.4-3.5.3-00053 and
QCA988x platform with firmware version: 10.2.4-1.0-00036.

some userspace programs (e.g. hostapd) need to set the regulatory domain
before selecting the operating channel. Synchronize DFS detector regardless of
the value of ah->curchan, to avoid situations where wireless scan can't be done
on some 5GHz sub-bands, because dfs_region is constantly UNSET.

fix iwlwifi_dev_ucode_error tracepoint to pass pointer to a table
instead of all 17 arguments by value.
dvm/main.c and mvm/utils.c have 'struct iwl_error_event_table'
defined with very similar yet subtly different fields and offsets.
tracepoint is still common and using definition of 'struct iwl_error_event_table'
from dvm/commands.h while copying fields.
Long term this tracepoint probably should be split into two.
