Apparently the e100.txt document contained a "License" section left
over from days of old, which does not need to be in the kernel
documentation. So clean it up..

git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211
Johannes Berg says:
====================
A small set of fixes for 4.4:
* fix scanning in mac80211 to not actively scan radar
channels (from Antonio)
* fix uninitialized variable in remain-on-channel that
could lead to treating frame TX as remain-on-channel
and not sending the frame at all
* remove NL80211_FEATURE_FULL_AP_CLIENT_STATE again, it
was broken and needs more work, we'll enable it later
* fix call_rcu() induced use-after-reset/free in mesh
(that was suddenly causing issues in certain tests)
* always request block-ack window size 64 as we found
some APs will otherwise crash (really ...)
* fix P2P-Device teardown sequence to avoid restarting
with uninitialized data

Enabling SR-IOV and then bringing the interface up was resulting in the PF
MAC addresses getting into a bad state. Specifically the MAC address was
enabled for both VF 0 and the PF. This resulted in some odd behaviors such
as VF 0 receiving a copy of the PFs traffic, which in turn enables the
ability for VF 0 to spoof the PF.
A workaround for this issue appears to be to bring up the interface first
and then enable SR-IOV as this way the reset is then triggered in the
existing code.
In order to correct this I have added a change to ixgbe_setup_tc where if
the interface is down we still will at least call ixgbe_reset so that the
MAC addresses for the device are reset to the correct pools.
Steps to reproduce issue:
modprobe ixgbe
echo 7 > /sys/bus/pci/devices/0000\:01\:00.1/sriov_numvfs
ifconfig enp1s0f1 up
ethregs -s 1:00.1 | grep MPSAR | grep -v 00000000
Result:
MPSAR[0] 00000081
MPSAR[254] 00000001
Expected Result, behavior after patch:
MPSAR[0] 00000080
MPSAR[254] 00000080

It is possible to address another chip on same MDIO bus. The case is
correctly handled for media advertising. It is taken into account
only if mii_data->phy_id == phydev->addr. However, this condition

Call bnxt_cfg_rx_mode() in bnxt_init_chip() to setup uc_list and
mc_list mac address filters. Before the patch, uc_list is not
setup again after chip reset (such as ethtool ring size change)
and macvlans don't work any more after that.
Modify bnxt_cfg_rx_mode() to return error codes appropriately so
that the init chip sequence can detect any failures.

For PF, the bp->pf.mac_addr always holds the permanent MAC
addr assigned by the HW. For VF, the bp->vf.mac_addr always
holds the administrator assigned VF MAC addr. The random
generated VF MAC addr should never get stored to bp->vf.mac_addr.
This way, when the VF wants to change the MAC address, we can tell
if the adminstrator has already set it and disallow the VF from
changing it.

The existing ndo_set_mac_address only copies the new MAC addr
and didn't set the new MAC addr to the HW. The correct way is
to delete the existing default MAC filter from HW and add
the new one. Because of RFS filters are also dependent on the
default mac filter l2 context, the driver must go thru
close_nic() to delete the default MAC and RFS filters, then
open_nic() to set the default MAC address to HW.

If the driver is used on an ARM platform with SPARSE_IRQ defined,
semantics of NR_IRQS is different (minimal value of virtual irqs) and
by default it is set to 16, see arch/arm/include/asm/irq.h.
This value may be less than the actual number of virtual irqs, which
may break the driver initialization. The check removal allows to use
the driver on such a platform, and, if irq controller driver works
correctly, the check is not needed on legacy platforms.

mq/mqprio have their own ways to report qlen/drops by folding stats on
all their queues, with appropriate locking.
A second problem is that qdisc_tree_decrease_qlen() calls qdisc_lookup()
without proper locking : concurrent qdisc updates could corrupt the list
that qdisc_match_from_root() parses to find a qdisc given its handle.
Fix first problem adding a TCQ_F_NOPARENT qdisc flag that
qdisc_tree_decrease_qlen() can use to abort its tree traversal,
as soon as it meets a mq/mqprio qdisc children.
Second problem can be fixed by RCU protection.
Qdisc are already freed after RCU grace period, so qdisc_list_add() and
qdisc_list_del() simply have to use appropriate rcu list variants.
A future patch will add a per struct netdev_queue list anchor, so that
qdisc_tree_decrease_qlen() can have more efficient lookups.

Each openvswitch tunnel vport (vxlan,gre,geneve) holds a reference
to the underlying tunnel device, but never released it when such
device is deleted.
Deleting the underlying device via the ip tool cause the kernel to

This commit ensure that on device unregistration dp_detach_port_notify()

'struct timeval tv' and 'struct timeval now' is used to calculate the
elapsed time. 'LIRC_SFH506_DELAY' is a delay t_phl in usecs.
32-bit systems using 'struct timeval' will break in the year 2038,
so we have to replace that code with more appropriate types.
This patch changes the lirc_parallel.c file of media: lirc driver
to use ktime_t.
ktime_get() is better than using do_gettimeofday(),
because it uses the monotonic clock. ktime_sub is used
to subtract two ktime variables. ktime_to_us() is used to
convert ktime to microsecond.
New ktime_t variable timeout, is added in lirc_off(),to improve
clarity. Introduced a new ktime_t variable in lirc_lirc_irq_handler()
function, to avoid the use of signal variable for storing
seconds in the first part of this function as later it uses
a time unit that is defined by the global "timer" variable.
This makes it more clear.
ktime_set() is used to set a value in seconds to a value in
nanosecond so that ktime_compare() can be used appropriately.
ktime_compare() is used to compare two ktime values.
ktime_add_ns() is used to increment a ktime value by 1 sec.
One comment is also shifted a line up, as it was creating a 80
character warning.

This patch changes the media: lirc driver to use ktime_t.

to subtract two ktime variables. The check to test time
going backwards is also removed. Intialization to static
variable is also removed. ktime_to_us() is used to convert
ktime_t to microsecond value. deltv is changed to delkt, a
ktime_t type varibale from long to assign the ktime_sub value
directly. ktime_compare is used to compare delkt with 15
seconds, which is changed to a nanosecond value by using
ktime_set().

The problem is that select and depend don't interact because Kconfig doesn't
have a SAT solver, so depend picks up dependencies and select does onward
selects, but select doesn't pick up dependencies. To fix this, we need to add
the correct dependencies to the MPT2SAS option like this.

Calling synchronize_irq() right before free_irq() is quite useless. On one
hand the IRQ can easily fire again before free_irq() is entered, on the
other hand free_irq() itself calls synchronize_irq() internally (in a race
condition free way), before any state associated with the IRQ is freed.

When a multicast group is joined on a socket, a struct ip_mc_socklist
is appended to the sockets mc_list containing information about the
joined group.
If the interface is hot unplugged, this entry becomes stale. Prior to
commit 52ad353a5344f ("igmp: fix the problem when mc leave group") it
was possible to remove the stale entry by performing a
IP_DROP_MEMBERSHIP, passing either the old ifindex or ip address on
the interface. However, this fix enforces that the interface must
still exist. Thus with time, the number of stale entries grows, until
sysctl_igmp_max_memberships is reached and then it is not possible to
join and more groups.
The previous patch fixes an issue where a IP_DROP_MEMBERSHIP is
performed without specifying the interface, either by ifindex or ip
address. However here we do supply one of these. So loosen the
restriction on device existence to only apply when the interface has
not been specified. This then restores the ability to clean up the
stale entries.

While testing the np->opt RCU conversion, I found that UDP/IPv6 was
using a mixture of xchg() and sk_dst_lock to protect concurrent changes
to sk->sk_dst_cache, leading to possible corruptions and crashes.
ip6_sk_dst_lookup_flow() uses sk_dst_check() anyway, so the simplest
way to fix the mess is to remove sk_dst_lock completely, as we did for
IPv4.
__ip6_dst_store() and ip6_dst_store() share same implementation.
sk_setup_caps() being called with socket lock being held or not,
we have to use sk_dst_set() instead of __sk_dst_set()
Note that I had to move the "np->dst_cookie = rt6_get_cookie(rt);"
in ip6_dst_store() before the sk_setup_caps(sk, dst) call.
This is because ip6_dst_store() can be called from process context,
without any lock held.
As soon as the dst is installed in sk->sk_dst_cache, dst can be freed
from another cpu doing a concurrent ip6_dst_store()
Doing the dst dereference before doing the install is needed to make
sure no use after free would trigger.

Because accounting resources for the root cgroup sometimes incurs
measureable overhead for workloads which don't care about cgroup and
often ends up calculating a number which is available elsewhere in a
slightly different form, cgroup is not in the business of providing
system-wide statistics. The pids controller which was introduced
recently was exposing "pids.current" at the root. This patch disable
accounting for root cgroup and removes the file from the root
directory.
While this is a userland visible behavior change, pids has been
available only in one version and was badly broken there, so I don't
think this will be noticeable. If it turns out to be a problem, we
can reinstate it for v1 hierarchies.

enabling
Consider the following v2 hierarchy.
P0 (+memory) --- P1 (-memory) --- A
\- B
P0 has memory enabled in its subtree_control while P1 doesn't. If
both A and B contain processes, they would belong to the memory css of
P1. Now if memory is enabled on P1's subtree_control, memory csses
should be created on both A and B and A's processes should be moved to
the former and B's processes the latter. IOW, enabling controllers
can cause atomic migrations into different csses.
The core cgroup migration logic has been updated accordingly but the
controller migration methods haven't and still assume that all tasks
migrate to a single target css; furthermore, the methods were fed the
css in which subtree_control was updated which is the parent of the
target csses. pids controller depends on the migration methods to
move charges and this made the controller attribute charges to the
wrong csses often triggering the following warning by driving a
counter negative.

This patch fixes the bug by removing @css parameter from the three
migration methods, ->can_attach, ->cancel_attach() and ->attach() and
updating cgroup_taskset iteration helpers also return the destination
css in addition to the task being migrated. All controllers are
updated accordingly.
* Controllers which don't care whether there are one or multiple
target csses can be converted trivially. cpu, io, freezer, perf,
netclassid and netprio fall in this category.
* cpuset's current implementation assumes that there's single source
and destination and thus doesn't support v2 hierarchy already. The
only change made by this patchset is how that single destination css
is obtained.
* memory migration path already doesn't do anything on v2. How the
single destination css is obtained is updated and the prep stage of
mem_cgroup_can_attach() is reordered to accomodate the change.
* pids is the only controller which was affected by this bug. It now
correctly handles multi-destination migrations and no longer causes
counter underflow from incorrect accounting.

freezer_attach()
If one or more tasks get moved into a frozen css, the frozen state is
cleared up from the destination css so that it can be reasserted once
the migrated tasks are frozen. freezer_attach() implements this in
two separate steps - clearing CGROUP_FROZEN on the target css while
processing each task and propagating the clearing upwards after the
task loop is done if necessary.
This patch merges the two steps. Propagation now takes place inside
the task loop. This simplifies the code and prepares it for the fix

It works only for HVR-4400/HVR-5500.
For WinTV-HVR-930C-HD it fails with bad/no reception
for unknown reasons.

The current si2165_set_frontend() function actually works only for DVB-T.
Split it into two functions, preparing the code to support DVB-C.

si2165_set_if_freq_shift() needs to call get_if_frequency() in order to do
the right shift. Add such logic inside the function, simplifying the logic
for the callers.

Datasheet says they must be rewritten after reset.
But it only makes sense to write them when trying to tune afterwards.

It is common the need of writing a table of values. Add a function to provide a
helper to address such case. This will allow further code cleanups.

Add the new match_reduced_fps argument to v4l2_match_dv_timings().
Depending on the situation you may or may not desire to match the
reduced_fps flag. Typically only HDMI transmitters will need to
check for this flag.

Contrary to what the datasheet says, the pre divider doesn't seem to be
incremented by one in the PLL2, but just uses the value from the register,
with 0 being a bypass.
This fixes the audio playing too fast.
Since we now have the same pre-divider flags, and the only difference with
the A10 is the post-divider offset, also remove the structure to just pass
the offset as an argument.

for_each_available_child_of_node performs an of_node_get on each iteration,
so a return from the middle of the loop requires an of_node_put.
A simplified version of the semantic patch that finds this problem is as
follows (http://coccinelle.lip6.fr):
// <smpl>

expression root,e;
