When finding the socket to report an error on, if the invoking packet
is using Segment Routing, the IPv6 destination address is that of an
intermediate router, not the end destination. Extract the ultimate
destination address from the segment address.
This change allows traceroute to function in the presence of Segment
Routing.

RFC8754 says:
ICMP error packets generated within the SR domain are sent to source
nodes within the SR domain. The invoking packet in the ICMP error
message may contain an SRH. Since the destination address of a packet
with an SRH changes as each segment is processed, it may not be the
destination used by the socket or application that generated the
invoking packet.
For the source of an invoking packet to process the ICMP error
message, the ultimate destination address of the IPv6 header may be
required. The following logic is used to determine the destination
address for use by protocol-error handlers.
* Walk all extension headers of the invoking IPv6 packet to the
routing extension header preceding the upper-layer header.
- If routing header is type 4 Segment Routing Header (SRH)
o The SID at Segment List[0] may be used as the destination
address of the invoking packet.
Mangle the skb so the network header points to the invoking packet
inside the ICMP packet. The seg6 helpers can then be used on the skb
to find any segment routing headers. If found, mark this fact in the
IPv6 control block of the skb, and store the offset into the packet of
the SRH. Then restore the skb back to its old state.

An ICMP error message can contain in its message body part of an IPv6
packet which invoked the error. Such a packet might contain a segment
router header. Export get_srh() so the ICMP code can make use of it.
Since his changes the scope of the function from local to global, add
the seg6_ prefix to keep the namespace clean. And move it into seg6.c
so it is always available, not just when IPV6_SEG6_LWTUNNEL is
enabled.

Add support for external timestamp and periodic signal output.
TJA1103 have one periodic signal and one external time stamp signal that
can be multiplexed on all 11 gpio pins.
The periodic signal can be only enabled or disabled. Have no start time
and if is enabled will be generated with a period of one second in sync
with the LTC seconds counter. The phase change is possible only with a
half of a second.
The external timestamp signal has no interrupt and no valid bit and
that's why the timestamps are handled by polling in .do_aux_work.

net/sched: Pass originating device to drivers offloading ct connection
Currently, drivers register to a ct zone that can be shared by multiple
devices. This can be inefficient for the driver to offload, as it
needs to handle all the cases where the tuple can come from,
instead of where it's most likely will arive from.
For example, consider the following tc rules:
tc filter add dev dev1 ... flower action ct commit zone 5 \
action mirred egress redirect dev dev2
tc filter add dev dev2 ... flower action ct zone 5 \
action goto chain chain 2
tc filter add dev dev2 ... flower ct_state +trk+est ... \
action mirred egress redirect dev dev1
Both dev2 and dev1 register to the zone 5 flow table (created
by act_ct). A tuple originating on dev1, going to dev2, will
be offloaded to both devices, and both will need to offload
both directions, resulting in 4 total rules. The traffic
will only hit originiating tuple on dev1, and reply tuple
on dev2.
By passing the originating device that created the connection
with the tuple, dev1 can choose to offload only the originating
tuple, and dev2 only the reply tuple. Resulting in a more
efficient offload.
The first patch adds an act_ct nf conntrack extension, to
temporarily store the originiating device from the skb before
offloading the connection once the connection is established.
Once sent to offload, it fills the tuple originating device.
The second patch get this information from tuples
which pass in openvswitch.
The third patch is Mellanox driver ct offload implementation using
this information to provide a hint to firmware of where this
offloaded tuple packets will arrive from (LOCAL or UPLINK port),
and thus increase insertion rate.
====================

Get originating device from tuple offload metadata match ingress_ifindex,
and set flow_source hint to either LOCAL for vf/sf reps, UPLINK for
uplink/wire/tunnel devices/bond, or ANY (as before this patch)
for all others.
This allows lower layer (software steering or firmware) to insert the tuple
rule only in one table (either rx or tx) instead of two (rx and tx).

Driver offloading ct tuples can use the information of which devices
received the packets that created the offloaded connections, to
more efficiently offload them only to the relevant device.
Add new act_ct nf conntrack extension, which is used to store the skb
devices before offloading the connection, and then fill in the tuple
iifindex so drivers can get the device via metadata dissector match.

There is no need to create kobject children of the pktcdvd device just
to display a subdirectory name. Instead, use a named attribute group
which removes the extra kobjects and also fixes the userspace race where
the device is created yet tools like libudev can not see the attributes
as they think the subdirectories are some other sort of device.

randomization
The config RANDOMIZE_SLAB does not exist, the authors probably intended to
refer to the config RANDOMIZE_BASE, which provides kernel address-space
randomization. They probably just confused SLAB with BASE (these two
four-letter words coincidentally share three common letters), as they also
point out the config SLAB_FREELIST_RANDOM as further randomization within
the same sentence.

all upper-case letters, as all Kconfig symbols are this way.
Properly capitalizing makes the script ./scripts/checkkconfigsymbols.py

So, use the right capitalization for the MAGIC_SYSRQ config in the kgdb

commit [1] causes missing bitmap updates when there isn't any WriteMostly

Detailed steps to reproduce by Norbert (which somehow didn't make to lore):
# setup md10 (raid1) with two drives (1 GByte sparse files)
dd if=/dev/zero of=disk1 bs=1024k seek=1024 count=0
dd if=/dev/zero of=disk2 bs=1024k seek=1024 count=0
losetup /dev/loop11 disk1
losetup /dev/loop12 disk2
mdadm --create /dev/md10 --level=1 --raid-devices=2 /dev/loop11 /dev/loop12
# add bitmap (aka write-intent log)
mdadm /dev/md10 --grow --bitmap=internal
echo check > /sys/block/md10/md/sync_action
root:# cat /sys/block/md10/md/mismatch_cnt
0
root:#
# remove member drive disk2 (loop12)
mdadm /dev/md10 -f loop12 ; mdadm /dev/md10 -r loop12
# modify degraded md device
dd if=/dev/urandom of=/dev/md10 bs=512 count=1
# no blocks recorded as out of sync on the remaining member disk1/loop11
root:# mdadm -X /dev/loop11 | grep Bitmap
Bitmap : 16 bits (chunks), 0 dirty (0.0%)
root:#
# re-add disk2, nothing synced because of empty bitmap
mdadm /dev/md10 --re-add /dev/loop12
# check integrity again
echo check > /sys/block/md10/md/sync_action
# disk1 and disk2 are no longer in sync, reads return differend data
root:# cat /sys/block/md10/md/mismatch_cnt
128
root:#
# clean up
mdadm -S /dev/md10
losetup -d /dev/loop11
losetup -d /dev/loop12
rm disk1 disk2
Fix this by moving the WriteMostly check to the if condition for

The function to retrieve battery info (from the device tree) assumes
we have a static info struct that gets populated by calling into
power_supply_get_battery_info().
This is awkward since I want to support tables of static battery
info by just assigning a pointer to all info based on e.g. a
compatible value in the device tree.
We also have a mixture of static and dynamically allocated
variables here.
Bite the bullet and let power_supply_get_battery_info() allocate
also the memory used for the very top level
struct power_supply_battery_info container. Pass pointers
around and lifecycle this with the psy device just like the
stuff we allocate inside it.
Change all current users over.
As part of the change, initializers need to be added to some
previously uninitialized fields in struct
power_supply_battery_info.

This is a leftover from when we used to independently swap the extent
root's commit root and the fs tree commit roots. At the time I simply
changed the helper to a list_add. There's actually no reason to not add
the extent root to the switch commit root at this point, we don't care
about the order we do the switching since it's all done under the
commit_root_sem.
If we re-mark the extent root dirty after adding it to the
switch_commits list we'll see that BTRFS_ROOT_DIRTY isn't set and then
list_move it back onto the dirty list, and then we'll redo the tree
update and everything will be ok.

If we're looking for leafs that point to a data extent we want to record
the extent items that point at our bytenr. At this point we have the
reference and we know for a fact that this leaf should have a reference
to our bytenr. However if there's some sort of corruption we may not
find any references to our leaf, and thus could end up with eie == NULL.
Replace this BUG_ON() with an ASSERT() and then return -EUCLEAN for the
mortals.

We search for an extent entry with .offset = -1, which shouldn't be a
thing, but corruption happens. Add an ASSERT() for the developers,
return -EUCLEAN for mortals.

We define __TRANS_DUMMY always, so this extra ifdef stuff is not needed.

This comment was much closer to the related code when it was originally
added, but has slowly migrated north far from its ancestral lands. Move
it back down with its people.

We pass in the path, but use btrfs_next_item() using the root we
searched with. Pass the root down to add_keyed_refs() instead of the
fs_info so we can continue to use the same root we searched with.
