[ Upstream commit ae15a41a64 ]
Originally in patch e6d20c55a4 ("openrisc: entry: Fix delay slot
detection") I fixed delay slot detection, but only for QEMU. We missed
that hardware delay slot detection using delay slot exception flag (DSX)
was still broken. This was because QEMU set the DSX flag in both
pre-exception supervision register (ESR) and supervision register (SR)
register, but on real hardware the DSX flag is only set on the SR
register during exceptions.
Fix this by carrying the DSX flag into the SR register during exception.
We also update the DSX flag read locations to read the value from the SR
register not the pt_regs SR register which represents ESR. The ESR
should never have the DSX flag set.
In the process I updated/removed a few comments to match the current
state. Including removing a comment saying that the DSX detection logic
was inefficient and needed to be rewritten.
I have tested this on QEMU with a patch ensuring it matches the hardware
specification.

[ Upstream commit 484c016d93 ]
Driver performs the internal reload when it receives tx-timeout event from
the OS. Internal reload might fail in some scenarios e.g., fatal HW issues.
In such cases OS still see the link, which would result in undesirable
functionalities such as re-generation of tx-timeouts.
The patch addresses this issue by indicating the link-down to OS when
tx-timeout is detected, and keeping the link in down state till the
internal reload is successful.
Please consider applying it to 'net' branch.

Commit 9757235f45, "nl80211: correct checks for
NL80211_MESHCONF_HT_OPMODE value") relaxed the range for the HT
operation field in meshconf, while also adding checks requiring
the non-greenfield and non-ht-sta bits to be set in certain
circumstances. The latter bit is actually reserved for mesh BSSes
according to Table 9-168 in 802.11-2016, so in fact it should not
be set.
wpa_supplicant sets these bits because the mesh and AP code share
the same implementation, but authsae does not. As a result, some
meshconf updates from authsae which set only the NONHT_MIXED
protection bits were being rejected.
In order to avoid breaking userspace by changing the rules again,
simply accept the values with or without the bits set, and mask
off the reserved bit to match the spec.
While in here, update the 802.11-2012 reference to 802.11-2016.

During assemble, the spare marked for replacement is not checked.
conf->fullsync cannot be updated to be 1. As a result, recovery will
treat it as a clean array. All recovering sectors are skipped. Original
device is replaced with the not-recovered spare.
mdadm -C /dev/md0 -l10 -n4 -pn2 /dev/loop[0123]
mdadm /dev/md0 -a /dev/loop4
mdadm /dev/md0 --replace /dev/loop0
mdadm -S /dev/md0 # stop array during recovery
mdadm -A /dev/md0 /dev/loop[01234]
After reassemble, you can see recovery go on, but it completes
immediately. In fact, recovery is not actually processed.
To solve this problem, we just add the missing logics for replacment
spares. (In raid1.c or raid5.c, they have already been checked.)

[ Upstream commit 9191fc2a43 ]
In the case of Station connects to AP with narrower bandwidth at beginning.
And later the AP changes the bandwidth to winder bandwidth, the AP will
beacon with wider bandwidth IE, eg VHT20->VHT40->VHT80 or VHT40->VHT80.
Since the supported BANDWIDTH will be limited by the PHYMODE, so while
Station receives the bandwidth change request, it will also need to
reconfigure the PHYMODE setting to firmware instead of just configuring
the BANDWIDTH info, otherwise it'll trigger a firmware crash with
non-support bandwidth.
The issue was observed in WLAN.RM.4.4.1-00051-QCARMSWP-1, QCA6174 with
below scenario:
AP xxx changed bandwidth, new config is 5200 MHz, width 2 (5190/0 MHz)
disconnect from AP xxx for new auth to yyy
RX ReassocResp from xxx (capab=0x1111 status=0 aid=102)

Make sure we are eswitch manager when coming to issue these callbacks
and err otherwise.
Also fix the definition of ESW_ALLOWED to rely on eswitch_manager
capability and on the vport_group_manger.
Operations on the VF nic vport context, such as setting a mac or reading
the vport counters are allowed to the PF in this scheme.
The modify nic vport guid code was modified to omit checking the
nic_vport_node_guid_modify eswitch capability.
The reason for doing so is that modifying node guid requires vport group
manager capability, and there's no need to check further capabilities.

The function addPassesToEmitFile signature changed in llvm 7.0 and such
a change caused the failure. This patch fixed the issue with using
proper function signatures under different compiler versions.

For some cases, the callchain provided by the kernel may be empty. So,
the callchain ip filtering code will cause a crash if we do not check
whether the struct ip_callchain pointer is NULL before accessing any
members.
This can be observed on a powerpc64le system running Fedora 27 as shown
below.

On s390 this test case fails because the socket identifiction numbers
assigned to the CPU are higher than the CPU identification numbers.
F/ix this by adding the platform architecture into the perf data header
flag information. This helps identifiing the test platform and handles
s390 specifics in process_cpu_topology().

[ Upstream commit b2d00d7c61 ]
The line numers for if-entries in the menu tree are off by one or more
lines which is confusing when debugging for correctness of unrelated changes.
According to the git log, commit a02f0570ae (kconfig: improve
error handling in the parser) was the last one that changed that part
of the parser and replaced
"if_entry: T_IF expr T_EOL"
by
"if_entry: T_IF expr nl"
but the commit message does not state why this has been done.
When reverting that part of the commit, only the line numers are
corrected (checked with cdebug = DEBUG_PARSE in zconf.y), otherwise
the menu tree remains unchanged (checked with zconfdump() enabled in
conf.c).
An example for the corrected line numbers:

It happens only when INT_MAX is passed there, as we're incrementing it
unconditionally. So the fix is trivial, check the value with
INT_MAX. Although the bug itself is fairly harmless, it's better to
fix it so that fuzzers won't hit this again later.

When a (broken) node wrongly sends multicast TT entries with a ROAM
flag then this causes any receiving node to drop all entries for the
same multicast MAC address announced by other nodes, leading to
packet loss.
Fix this DoS vector by only storing TT sync flags. For multicast TT
non-sync'ing flag bits like ROAM are unused so far anyway.

A reference for the best gateway is taken when the list of gateways in the

then transferred as flag BATADV_ATTR_FLAG_BEST.
After the comparison of the current entry is done,
batadv_v_gw_dump_entry() has to decrease the reference counter again.
Otherwise the reference will be held and thus prevents a proper shutdown of
