Since its inception, ceph has presented the fsid as an opaque value
without any sort of endianness conversion. This means that the value
presented is different on architectures of different endianness.
While the value that should be stuffed into f_fsid is poorly-defined,
I think it would be best to strive for consistency here between
architectures, and clients (we need to present this properly to the
userland client as well).
Change ceph_statfs to convert the opaque words to host-endian before
doing the xor. On an upgrade, a big-endian box may see a different fsid
than it did before, but little-endian arches should see no change with
this patch.

->open_count/-EBUSY check is bogus and wrong: when an open device is
set read-only, blkdev_write_iter() refuses further writes with -EPERM.
This is standard behaviour and all other block devices allow this.
set_disk_ro() call is also problematic: we affect the entire device
when called on a single partition.
All rbd_ioctl_set_ro() needs to do is refuse ro -> rw transition for
mapped snapshots. Everything else can be handled by generic code.

When session get evicted, all file locks associated with the session
get released remotely by mds. File locks tracked by kernel become
stale. In this situation, set an error flag on inode. The flag makes

Another option to handle this situation is cleanup file locks tracked

====================
net: improve the process of redirect and toobig for ipv6 tunnels
Now let's say there are 3 kinds of icmp packets to process for tunnels,
toobig(needfrag), redirect, others, their process should be:
- toobig(needfrag)
update the lower dst's pmtu by route cache, also update sk dst's pmtu
if possible, or it will be fine if sk dst pmtu will get updated on tx
path.
- redirect
update the lower dst's gw by route cache and return, no need to send
this redirect packet to user sk.
- others
send the packet to user's sk, or it will also be fine to use err_count
to count it and report fail link on tx path.
All ipv4 tunnels basically follow this while some of ipv6 tunnels are
doing in different ways, like ip6gre and ip6_tunnels update tnl dev's
mtu instead of updating lower dst pmtu, no redirect process on their
err_handlers, which doesn't make any sense and even causes performance
problems.
This patchset is to improve the process of redirect and toobig for ip6gre
ip4ip6, ip6ip6 tunnels, as in ipv4 tunnels.

Note that redirect icmp packet is already processed in ip6_tnl_err,
the old redirect codes in ip4ip6_err actually never worked even
before this patch. Besides, there's no need to send redirect to
user's sk, it's for lower dst, so just remove it in this patch.

Now ip6gre processes toobig icmp packet by setting gre dev's mtu in
ip6gre_err, which would cause few things not good:
- It couldn't set mtu with dev_set_mtu due to it's not in user context,
which causes route cache and idev->cnf.mtu6 not to be updated.
- It has to update sk dst pmtu in tx path according to gredev->mtu for
ip6gre, while it updates pmtu again according to lower dst pmtu in
ip6_tnl_xmit.
- To change dev->mtu by toobig icmp packet is not a good idea, it should
only work on pmtu.
This patch is to process toobig by updating the lower dst's pmtu, as later
sk dst pmtu will be updated in ip6_tnl_xmit, the same way as in ip4gre.
Note that gre dev's mtu will not be updated any more, it doesn't make any
sense to change dev's mtu after receiving a toobig packet.

Openvswitch meter action
This patch series is the first attempt to add openvswitch
meter support. We have previously experimented with adding
metering support in nftables. However 1) It was not clear
how to expose a named nftables object cleanly, and 2)
the logic that implements metering is quite small, < 100 lines
of code.
With those two observations, it seems cleaner to add meter
support in the openvswitch module directly.

net: dsa: b53: Support prepended Broadcom tags
This patch series adds support for prepended 4-bytes Broadcom tags that we

a SoC like BCM58xx (NorthStar Plus) which supports a Flow Accelerator (WIP).
In that case, we need to support a slightly different tagging format.
The first patch does a bit of re-factoring and passes a port index to

that type of information (mt7530, b53) to support tagging or not.

The way people generally use netlink_dump is that they fill in the skb
as much as possible, breaking when nla_put returns an error. Then, they
get called again and start filling out the next skb, and again, and so
forth. The mechanism at work here is the ability for the iterative
dumping function to detect when the skb is filled up and not fill it
past the brim, waiting for a fresh skb for the rest of the data.
However, if the attributes are small and nicely packed, it is possible
that a dump callback function successfully fills in attributes until the
skb is of size 4080 (libmnl's default page-sized receive buffer size).
The dump function completes, satisfied, and then, if it happens to be
that this is actually the last skb, and no further ones are to be sent,
then netlink_dump will add on the NLMSG_DONE part:
nlh = nlmsg_put_answer(skb, cb, NLMSG_DONE, sizeof(len), NLM_F_MULTI);
It is very important that netlink_dump does this, of course. However, in
this example, that call to nlmsg_put_answer will fail, because the
previous filling by the dump function did not leave it enough room. And
how could it possibly have done so? All of the nla_put variety of
functions simply check to see if the skb has enough tailroom,
independent of the context it is in.
In order to keep the important assumptions of all netlink dump users, it
is therefore important to give them an skb that has this end part of the
tail already reserved, so that the call to nlmsg_put_answer does not
fail. Otherwise, library authors are forced to find some bizarre sized
receive buffer that has a large modulo relative to the common sizes of
messages received, which is ugly and buggy.
This patch thus saves the NLMSG_DONE for an additional message, for the
case that things are dangerously close to the brim. This requires
keeping track of the errno from ->dump() across calls.

netem: add nsec scheduling and slot feature
This patch series converts netem away from the old "ticks" interface and

Slotting is a crude approximation of the behaviors of shared media such
as cable, wifi, and LTE, which gather up a bunch of packets within a
varying delay window and deliver them, relative to that, nearly all at
once.
It works within the existing loss, duplication, jitter and delay
parameters of netem. Some amount of inherent latency must be specified,
regardless.
The new "slot" parameter specifies a minimum and maximum delay between
transmission attempts.
The "bytes" and "packets" parameters can be used to limit the amount of
information transferred per slot.
Examples of use:
tc qdisc add dev eth0 root netem delay 200us \
slot 800us 10ms bytes 64k packets 42
A more correct example, using stacked netem instances and a packet limit
to emulate a tail drop wifi queue with slots and variable packet
delivery, with a 200Mbit isochronous underlying rate, and 20ms path
delay:
tc qdisc add dev eth0 root handle 1: netem delay 20ms rate 200mbit \
limit 10000
tc qdisc add dev eth0 parent 1:1 handle 10:1 netem delay 200us \

netem userspace has long relied on a horrible /proc/net/psched hack
to translate the current notion of "ticks" to nanoseconds.
Expressing latency and jitter instead, in well defined nanoseconds,
increases the dynamic range of emulated delays and jitter in netem.
It will also ease a transition where reducing a tick to nsec
equivalence would constrain the max delay in prior versions of
netem to only 4.3 seconds.

from June 2004.
To expose the required load address information, Jonathan added the
sections subdirectory for every module in /sys/modules, and made them
S_IRUGO - readable by everybody.
It was a more innocent time, plus those S_IRxxx macro names are a lot
more confusing than the octal numbers are, so maybe it wasn't even
intentional. But here we are, thirteen years later, and I'll just change
it to S_IRUSR instead.
Let's see if anybody even notices.
