netfilter: nf_conntrack: prepare namespace support for l3 protocol trackers
This patch prepares the namespace support for layer 3 protocol trackers.
Basically, this modifies the following interfaces:
* nf_ct_l3proto_[un]register_sysctl.
* nf_conntrack_l3proto_[un]register.
We add a new nf_ct_l3proto_net is used to get the pernet data of l3proto.
This adds rhe new struct nf_ip_net that is used to store the sysctl header
and l3proto_ipv4,l4proto_tcp(6),l4proto_udp(6),l4proto_icmp(v6) because the
protos such tcp and tcp6 use the same data,so making nf_ip_net as a field
of netns_ct is the easiest way to manager it.
This patch also adds init_net to struct nf_conntrack_l3proto to initial
the layer 3 protocol pernet data.

dm thin: provide userspace access to pool metadata
This patch implements two new messages that can be sent to the thin
pool target allowing it to take a snapshot of the _metadata_. This,
read-only snapshot can be accessed by userland, concurrently with the
live target.
Only one metadata snapshot can be held at a time. The pool's status
line will give the block location for the current msnap.
Since version 0.1.5 of the userland thin provisioning tools, the
thin_dump program displays the msnap as follows:
thin_dump -m <msnap root> <metadata dev>
Available here: https://github.com/jthornber/thin-provisioning-tools
Now that userland can access the metadata we can do various things
that have traditionally been kernel side tasks:
i) Incremental backups.
By using metadata snapshots we can work out what blocks have
changed over time. Combined with data snapshots we can ensure
the data doesn't change while we back it up.
A short proof of concept script can be found here:
https://github.com/jthornber/thinp-test-suite/blob/master/incremental_backup_example.rb
ii) Migration of thin devices from one pool to another.
iii) Merging snapshots back into an external origin.
iv) Asyncronous replication.

dm mpath: allow ioctls to trigger pg init
After the failure of a group of paths, any alternative paths that
need initialising do not become available until further I/O is sent to
the device. Until this has happened, ioctls return -EAGAIN.
With this patch, new paths are made available in response to an ioctl
too. The processing of the ioctl gets delayed until this has happened.
Instead of returning an error, we submit a work item to kmultipathd
(that will potentially activate the new path) and retry in ten
milliseconds.
Note that the patch doesn't retry an ioctl if the ioctl itself fails due
to a path failure. Such retries should be handled intelligently by the
code that generated the ioctl in the first place, noting that some SCSI
commands should not be retried because they are not idempotent (XOR write
commands). For commands that could be retried, there is a danger that
if the device rejected the SCSI command, the path could be errorneously
marked as failed, and the request would be retried on another path which
might fail too. It can be determined if the failure happens on the
device or on the SCSI controller, but there is no guarantee that all
SCSI drivers set these flags correctly.

This series has not been part of linux-next and is based on top of the

x86, x32, ptrace: Remove PTRACE_ARCH_PRCTL for x32
When I added x32 ptrace to 3.4 kernel, I also include PTRACE_ARCH_PRCTL
support for x32 GDB For ARCH_GET_FS/GS, it takes a pointer to int64. But
at user level, ARCH_GET_FS/GS takes a pointer to int32. So I have to add
x32 ptrace to glibc to handle it with a temporary int64 passed to kernel and
copy it back to GDB as int32. Roland suggested that PTRACE_ARCH_PRCTL
is obsolete and x32 GDB should use fs_base and gs_base fields of
user_regs_struct instead.
Accordingly, remove PTRACE_ARCH_PRCTL completely from the x32 code to
avoid possible memory overrun when pointer to int32 is passed to
kernel.

cipso: handle CIPSO options correctly when NetLabel is disabled
When NetLabel is not enabled, e.g. CONFIG_NETLABEL=n, and the system
receives a CIPSO tagged packet it is dropped (cipso_v4_validate()
returns non-zero). In most cases this is the correct and desired
behavior, however, in the case where we are simply forwarding the
traffic, e.g. acting as a network bridge, this becomes a problem.
This patch fixes the forwarding problem by providing the basic CIPSO
validation code directly in ip_options_compile() without the need for
the NetLabel or CIPSO code. The new validation code can not perform
any of the CIPSO option label/value verification that
cipso_v4_validate() does, but it can verify the basic CIPSO option
format.
The behavior when NetLabel is enabled is unchanged.

x86: get rid of calling do_notify_resume() when returning to kernel mode
If we end up calling do_notify_resume() with !user_mode(refs), it
does nothing (do_signal() explicitly bails out and we can't get there
with TIF_NOTIFY_RESUME in such situations). Then we jump to
resume_userspace_sig, which rechecks the same thing and bails out
to resume_kernel, thus breaking the loop.
It's easier and cheaper to check *before* calling do_notify_resume()
and bail out to resume_kernel immediately. And kill the check in
do_signal()...
Note that on amd64 we can't get there with !user_mode() at all - asm

nfs: don't open in ->d_revalidate
NFSv4 can't do reliable opens in d_revalidate, since it cannot know whether a
mount needs to be followed or not. It does check d_mountpoint() on the dentry,
which can result in a weird error if the VFS found that the mount does not in
fact need to be followed, e.g.:
# mount --bind /mnt/nfs /mnt/nfs-clone
# echo something > /mnt/nfs/tmp/bar
# echo x > /tmp/file
# mount --bind /tmp/file /mnt/nfs-clone/tmp/bar
# cat /mnt/nfs/tmp/bar
cat: /mnt/nfs/tmp/bar: Not a directory
Which should, by any sane filesystem, result in "something" being printed.
So instead do the open in f_op->open() and in the unlikely case that the cached
dentry turned out to be invalid, drop the dentry and return EOPENSTALE to let
the VFS retry.

has always done, updates the time and marks the inode dirty, and then
filesystems can choose to do something different.

"This includes a fairly large change from Josef around data writeback
completion. Before, the writeback wasn't completed until the metadata
insertions for the extent were done, and this made for fairly large
latency spikes on the last page of each ordered extent.
We already had a separate mechanism for tracking pending metadata
insertions, so Josef just needed to tweak things a little to end
writeback earlier on the page. Overall it makes us much friendly to
memory reclaim and lowers latencies quite a lot for synchronous IO.
Jan Schmidt has finished some background work required to track btree
blocks as they go through changes in ownership. It's the missing
piece he needed for both btrfs send/receive and subvolume quotas.
Neither of those are ready yet, but the new tracking code is included
here. Most of the time, the new code is off. It is only used by
scrub and other backref walkers.
Stefan Behrens has added io failure tracking. This includes counters
for which drives are causing the most trouble so the admin (or an
automated tool) can choose to kick them out. We're tracking IO
errors, crc errors, and generation checks we do on each metadata
block.
