This fixes the daemon's failure to start when setting --ipv6=true for
the first time without deleting `docker0` bridge from a prior use with
only IPv4 addressing.
The addition of the IPv6 bridge address is factored out into a separate
initialization routine which is called even if the bridge exists but no
IPv6 addresses are found.

Under certain cases, such as when putting a manifest or check for the existence
of a layer, the status code checks in session_v2.go were too narrow for their
purpose. In the case of putting a manifest, the handler only cares that an
error is not returned. Whether it is a 304 or 202 does not matter, as long as
the server reports success. Having the client only accept specific http codes
inhibits future protocol evolution.

The build job will sometimes trigger a pull job when the base image
does not exist. Now that engine jobs properly close their output by default
the pull job would also close the build job's stdout in a cascading close
upon completion of the pull.
This patch corrects this by wrapping the `pull` job's stdout with a
nopCloseWriter which will not close the stdout of the `build` job.

Addresses #5811
This cleans up an error in the logic which removes localhost resolvers
from the host resolv.conf at container creation start time. Specifically
when the determination is made if any nameservers are left after
removing localhost resolvers, it was using a string match on the word
"nameserver", which could have been anywhere (including commented out)
leading to incorrect situations where no nameservers were left but the
default ones were not added.
This also adds some complexity to the regular expressions for finding
nameservers in general, as well as matching on localhost resolvers due
to the recent addition of IPv6 support. Because of IPv6 support now
available in the Docker daemon, the resolvconf code is now aware of
IPv6 enable/disable state and uses that for both filter/cleaning of
nameservers as well as adding default Google DNS (IPv4 only vs. IPv4
and IPv6 if IPv6 enabled). For all these changes, tests have been
added/strengthened to test these additional capabilities.

We want to be able to use container without the PID namespace. We basically
want containers that can manage the host os, which I call Super Privileged
Containers. We eventually would like to get to the point where the only
namespace we use is the MNT namespace to bring the Apps userspace with it.
By eliminating the PID namespace we can get better communication between the
host and the clients and potentially tools like strace and gdb become easier
to use. We also see tools like libvirtd running within a container telling
systemd to place a VM in a particular cgroup, we need to have communications of the PID.
I don't see us needing to share PID namespaces between containers, since this
is really what docker exec does.
So currently I see us just needing docker run --pid=host

Usage statement should only be printed when the user asks for it.
Errors should print error message and then suggest the docker COMMAND --help
command to see usage information.
The current behaviour causes the user to have to search for the error message
and sometimes scrolls right off the screen. For example a error on a

Finally erros should always exit with a non 0 exit code, if the user

There has been a lot of discussion (issues 4242 and 5262) about making
`FROM scratch` either a special case or making `FROM` optional, implying
starting from an empty file system.
This patch makes the build command `FROM scratch` special cased from now on
and if used does not pull/set the the initial layer of the build to the ancient
image ID (511136ea..) but instead marks the build as having no base image. The
next command in the dockerfile will create an image with a parent image ID of "".
This means every image ever can now use one fewer layer!
This also makes the image name `scratch` a reserved name by the TagStore. You
will not be able to tag an image with this name from now on. If any users
currently have an image tagged as `scratch`, they will still be able to use that
image, but will not be able to tag a new image with that name.

Fixes#6647: Other upstart jobs that depend on docker by specifying
"start on started docker" would often start before the docker daemon was
ready, so they'd fail with "Cannot connect to the Docker daemon" or
"dial unix /var/run/docker.sock: no such file or directory".
This is because "docker -d" doesn't daemonize, it runs in the
foreground, so upstart can't know when the daemon is ready to receive
incoming connections. (Traditionally, a daemon will create all necessary
sockets and then fork to signal that it's ready; according to @tianon
this "isn't possible in Go"[1]. See also [2].)
Presumably this isn't a problem with systemd init with its socket
activation. The SysV init scripts may or may not suffer from this
problem but I have no motivation to fix them.
This commit adds a "post-start" stanza to the upstart configuration
that waits for the socket to be available. Upstart won't emit the
"started" event until the "post-start" script completes.[3]
Note that the system administrator might have specified a different path
for the socket, or a tcp socket instead, by customising
/etc/default/docker. In that case we don't try to figure out what the
new socket is, but at least we don't wait in vain for
/var/run/docker.sock to appear.
If the main script (`docker -d`) fails to start, the `initctl status
$UPSTART_JOB | grep -q "stop/"` line ensures that we don't loop forever.
I stole this idea from Steve Langasek.[4]
If for some reason we *still* end up in an infinite loop --I guess
`docker -d` must have hung-- then at least we'll be able to see the
"Waiting for /var/run/docker.sock" debug output in
/var/log/upstart/docker.log.
I considered using inotifywait instead of sleep, but it isn't worth
the complexity & the extra dependency.

When we use the engine/env object we can run into a situation where
a string is passed in as the value but later on when we json serialize
the name/value pairs, because the string is made up of just numbers
it appears as an integer and not a string - meaning no quotes. This
can cause parsing issues for clients.
I tried to find all spots where we call env.Set() and the type of the
name being set might end up having a value that could look like an int
(like author). In those cases I switched it to use env.SetJson() instead
because that will wrap it in quotes.
One interesting thing to note about the testcase that I modified is that
the escaped quotes should have been there all along and we were incorrectly
letting it thru. If you look at the metadata stored for that resource you
can see the quotes were escaped and we lost them during the serialization
steps because of the env.Set() stuff. The use of env is probably not the
best way to do all of this.

- Create device metadata file

If docker crashes anywhere in between without closing transaction, then

Currently devicemapper backend does not keep track of used device Ids in
the pool. It tries a device Id and if that device Id exists in pool, it
tries with a different Id and keeps on doing this in a loop till it succeeds.
This worked fine so far but now we are moving to transaction based
device creation and deletion. We will keep deviceId information in
transaction which will be rolled back if docker crashed before transaction
was complete.
If we store a deviceId in transaction and later figure out it already
existed in pool and docker crashed, then we will rollback and remove
that existing device Id from pool (which we should not have).
That means, we should know free device Id in pool in advance before
we put that device Id in transaction.
Hence this patch creates a bitmap (one bit each for a deviceId), and
sets the bit if device Id is used otherwise resets it. This patch
is just preparing the ground right now. Actual usage will follow
in later patches.

Very soon we will have the notion of an open transaction and keep its

When a new transaction is opened, we allocate a new transaction Id,

I thought that OpenTransactionId better represents the semantics of
transaction Id associated with an open transaction instead of NewtransactionId.
This patch just does the renaming. No functionality change.

Currently new transaction Id is created using allocateTransactionId()
function. This function takes NewTransactionId and bumps up by one
to create NewTransactionId.
I think ideally we should be bumping up devices.TransactionId by 1
to come up with NewTransactionId. Because idea is that devices.TransactionId
contains the current pool transaction Id and to come up with a new
transaction Id bump it up by one.
Current code is not wrong as we are keeping NewTransactionId and
TransactionId in sync. But it will be more direct if we look at
devices.TransactionId to come up with NewTransactionId. That way
we don't have to even initialize NewTransactionId during startup
as first time somebody wants to do a transaction, it will be
allocated fresh.
So simplify the code a bit. No functionality change.

Currently updatePoolTransactionId() checks if NewTransactionId and

new transaction Id otherwise it does not make any sense.

Currently devicemapper CreateDevice and CreateSnapDevice keep on retrying

With new transaction mechanism we need to store device id in transaction

So change the logic in such a way that caller decides the devices Id to
use. If that device Id is not available, caller bumps up the device Id
and retries.
That way caller can update transaciton too when it tries a new Id. Transaction

Signed-off-by: Vivek Goyal <vgoyal@redhat.com>
Current code is associating a transaction id with each device and if pool
transaction id is greater that value, then current code assumes that device
is there in pool.
Transaction id of pool is a mechanism so that during device creation and
removal one can define a transaction and during startup figure out if
transaction was complete or not. I think we are using transaction id
throughout the code little inappropriately.
For example, if a device is being deleted, it is possible that we deleted
the device from pool but before we could delete metafile docker crashed.
When docker comes back it will think that device is in the pool (due to
device transaction id being less than pool transaction id) but device
is not in the pool.
Similary, it could happen that some data in the pool is corrupted and
during pool repair some devices are lost (without docker knowing about
it). In that case tool pool transaction id will be higher than device
transaction id and there are no guaratees that device is actually in
the pool.
So move away from this model where we think that a device is in pool if pool
transaction id is greater than device transaction Id. Per device
transaction Id just says that after device creation this should be pool's
transaction Id and nothing more.
Transaction id is per pool property (as opposed to per device property) and
will be used internally to figure out if last transaction was complete or
not and recover from failure during docker startup.
If for some reason metafile is present but device is not in pool, then
device activation will fail later.

I noticed that 3 of the tarsum test cases had expected a tarsum with
a sha256 hash of
e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855
As I've been working with sha256 quite a bit lately, it struck me that
this is the initial digest value for sha256, which means that no data
was processed. However, these tests *do* process data. It turns out that
there was a bug in the test handling code which did not wait for tarsum
to end completely. This patch corrects these test cases.
I'm unaware of anywhere else in the code base where this would be an issue,
though we definitily need to look out in the future to ensure we are
completing tarsum reads (waiting for EOF).

We can safely move this field from the Config to the HostConfig

Ideally lvm2 would be used to create/manage the thin-pool volume that is
then handed to docker to exclusively create/manage the thin and thin

outside of docker makes for the most feature-rich method of having
docker utilize device mapper thin provisioning as the backing storage
for docker's containers. lvm2-based thin-pool management feature
highlights include: automatic or interactive thin-pool resize support,
dynamically change thin-pool features, automatic thinp metadata checking
when lvm2 activates the thin-pool, etc.
Docker will not activate/deactivate the specified thin-pool device but
it will exclusively manage/create thin and thin snapshot volumes in it.
Docker will not take ownership of the specified thin-pool device unless
it has 0 data blocks used and a transaction id of 0. This should help
guard against using a thin-pool that is already in use.

The way thin-pool right now is designed, user space is supposed to keep
track of what device ids have already been used. If user space tries to
create a new thin/snap device and device id has already been used, thin
pool retuns -EEXIST.
Upon receiving -EEXIST, current docker implementation simply tries the
NextDeviceId++ and keeps on doing this till it finds a free device id.
This approach has two issues.
- It is little suboptimal.
- If device id already exists, current kenrel implementation spits out
a messsage on console.
[17991.140135] device-mapper: thin: Creation of new snapshot 33 of device 3 failed.
Here kenrel is trying to tell user that device id 33 has already been used.
And this shows up for every device id docker tries till it reaches a point
where device ids are not used. So if there are thousands of container and
one is trying to create a new container after fresh docker start, expect
thousands of such warnings to flood console.
This patch saves the NextDeviceId in a file in
/var/lib/docker/devmapper/metadata/deviceset-metadata and reads it back
when docker starts. This way we don't retry lots of device ids which
have already been used.
There might be some device ids which are free but we will get back to them
once device numbers wrap around (24bit limit on device ids).
This patch should cut down on number of kernel warnings.
Notice that I am creating a deviceset metadata file which is a global file
for this pool. So down the line if we need to save more data we should be
able to do that.

Currently we save device metadata and have a helper function saveMetadata()
which converts data in json format as well as saves it to file. For
converting data in json format, one needs to know what is being saved.
Break this function down in two functions. One function only has file
write capability and takes in argument about byte array of json data.
Now this function does not have to know what data is being saved. It
only knows about a stream of json data is being saved to a file.
This allows me to reuse this function to save a different type of
metadata. In this case I am planning to save NextDeviceId so that
docker can use this device Id upon next restart. Otherwise docker
starts from 0 which is suboptimal.

This re-applies commit b39d02b with additional iptables rules to solve the issue with containers routing back into themselves.
The previous issue with this attempt was that the DNAT rule would send traffic back into the container it came from. When this happens you have 2 issues.
1) reverse path filtering. The container is going to see the traffic coming in from the outside and it's going to have a source address of itself. So reverse path filtering will kick in and drop the packet.
2) direct return mismatch. Assuming you turned reverse path filtering off, when the packet comes back in, it's goign to have a source address of itself, thus when the reply traffic is sent, it's going to have a source address of itself. But the original packet was sent to the host IP address, so the traffic will be dropped because it's coming from an address which the original traffic was not sent to (and likely with an incorrect port as well).
The solution to this is to masquerade the traffic when it gets routed back into the origin container. However for this to work you need to enable hairpin mode on the bridge port, otherwise the kernel will just drop the traffic.
The hairpin mode set is part of libcontainer, while the MASQ change is part of docker.

While working on the fix for #8330 I noticed a few things:
1 - the split() call for the .dockerignore process will generate a blank
"exclude". While this isn't causing an issue right now, I got worried
that in the future some code later on might interpret "" as something bad,
like "everything" or ".". So I added a check for an empty "exclude"
and skipped it
2 - if someone puts "foo" in their .dockerignore then we'll skip "foo".
However, if they put "./foo" then we won't due to the painfully
simplistic logic of go's filepath.Match algorithm. To help things
a little (and to treat ./Dockerfile just like Dockerfile) I added
code to filepath.Clean() each entry in .dockerignore. It should
result in the same semantic path but ensure that no matter how the
user expresses the path, we'll match it.

In an effort to make layer content 'stable' between import
and export from two different graph drivers, we must resolve
an issue where AUFS produces metadata files in its layers
which other drivers explicitly ignore when importing.
The issue presents itself like this:
- Generate a layer using AUFS
- On commit of that container, the new stored layer contains
AUFS metadata files/dirs. The stored layer content has some
tarsum value: '1234567'
- `docker save` that image to a USB drive and `docker load`
into another docker engine instance which uses another
graph driver, say 'btrfs'
- On load, this graph driver explicitly ignores any AUFS metadata
that it encounters. The stored layer content now has some
different tarsum value: 'abcdefg'.
The only (apparent) useful aufs metadata to keep are the psuedo link
files located at `/.wh..wh.plink/`. Thes files hold information at the
RW layer about hard linked files between this layer and another layer.
The other graph drivers make sure to copy up these psuedo linked files
but I've tested out a few different situations and it seems that this
is unnecessary (In my test, AUFS already copies up the other hard linked
files to the RW layer).
This changeset adds explicit exclusion of the AUFS metadata files and
directories (NOTE: not the whiteout files!) on commit of a container
using the AUFS storage driver.
Also included is a change to the archive package. It now explicitly
ignores the root directory from being included in the resulting tar archive
for 2 reasons: 1) it's unnecessary. 2) It's another difference between
what other graph drivers produce when exporting a layer to a tar archive.

This backend uses the overlayfs union filesystem for containers
plus hard link file sharing for images.
Each container/image can have a "root" subdirectory which is a plain
filesystem hierarchy, or they can use overlayfs.
If they use overlayfs there is a "upper" directory and a "lower-id"
file, as well as "merged" and "work" directories. The "upper"
directory has the upper layer of the overlay, and "lower-id" contains
the id of the parent whose "root" directory shall be used as the lower
layer in the overlay. The overlay itself is mounted in the "merged"
directory, and the "work" dir is needed for overlayfs to work.
When a overlay layer is created there are two cases, either the
parent has a "root" dir, then we start out with a empty "upper"
directory overlaid on the parents root. This is typically the
case with the init layer of a container which is based on an image.
If there is no "root" in the parent, we inherit the lower-id from
the parent and start by making a copy if the parents "upper" dir.
This is typically the case for a container layer which copies
its parent -init upper layer.
Additionally we also have a custom implementation of ApplyLayer
which makes a recursive copy of the parent "root" layer using
hardlinks to share file data, and then applies the layer on top
of that. This means all chile images share file (but not directory)
data with the parent.

The vfs storage driver currently shells out to the `cp` binary on the host
system to perform an 'archive' copy of the base image to a new directory.
The archive option preserves the modified time of the files which are created
but there was an issue where it was unable to preserve the modified time of
copied symbolic links on some host systems with an outdated version of `cp`.
This change no longer relies on the host system implementation and instead
utilizes the `CopyWithTar` function found in `pkg/archive` which is used
to copy from source to destination directory using a Tar archive, which
should correctly preserve file attributes.

If we first request port 49153 (BeginPortRange) explicitly, and later some time request the next free port (of same ip/proto) by calling RequestPort() with port number 0, we will again get 49153 returned, even if it's currently in use. Because findPort() blindly retured BeginPortRange the first run, without checking if it has already been taken.

Do not run containers in the background in the integration tests if you
depend on the run completing. It is better especially if you just want
to ensure that the run has completed with a `true` to just run in
foreground and use a known name for the container to query it after it
has stopped.
The failures can be reproduced on most machines by giving your dind
container one core and a cpushare.

Fixes#1992
Right now when you `docker cp` a path which is in a volume, the cp
itself works, however you end up getting files that are in the
container's fs rather than the files in the volume (which is not in the
container's fs).
This makes it so when you `docker cp` a path that is in a volume it
follows the volume to the real path on the host.
archive.go has been modified so that when you do `docker cp mydata:/foo
.`, and /foo is the volume, the outputed folder is called "foo" instead
of the volume ID (because we are telling it to tar up
`/var/lib/docker/vfs/dir/<some id>` and not "foo", but the user would be
expecting "foo", not the ID

We do this to prevent leakage of information, we don't want people
to be able to probe for existing content.
According to RFC 2616, "This status code (404) is commonly used when the server does not
wish to reveal exactly why the request has been refused, or when no other response i
is applicable."
https://www.ietf.org/rfc/rfc2616.txt
10.4.4 403 Forbidden
The server understood the request, but is refusing to fulfill it.
Authorization will not help and the request SHOULD NOT be repeated.
If the request method was not HEAD and the server wishes to make
public why the request has not been fulfilled, it SHOULD describe the
reason for the refusal in the entity. If the server does not wish to
make this information available to the client, the status code 404
(Not Found) can be used instead.
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No
indication is given of whether the condition is temporary or
permanent. The 410 (Gone) status code SHOULD be used if the server
knows, through some internally configurable mechanism, that an old
resource is permanently unavailable and has no forwarding address.
This status code is commonly used when the server does not wish to
reveal exactly why the request has been refused, or when no other
response is applicable.
When docker is running through its certificates, it should continue
trying with a new certificate even if it gets back a 404 error code.

First off, sorry for the noise. This is a cleaner step of #8508
Found more of a root cause of the open file handles.
After more testing I found that the open file descriptors will still
occur for TCP:// connections to the daemon, causing client and/or daemon
to fail.
The issue was instantiating a new http.Transport on _ever_ client
request. So each instance held the prior connection alive, but was only
ever used once.
By moving it out to the initilization of DockerCli, we can now have
reuse of idled connections. Simplifies the garbage overhead of the
client too, though that's not usually a deal.

+ Dockerfile to use for a given `docker build` can be specified with the `-f` flag
* Dockerfile and .dockerignore files can be themselves excluded as part of the .dockerignore file, thus preventing modifications to these files invalidating ADD or COPY instructions cache
* ADD and COPY instructions accept relative paths
* Dockerfile `FROM scratch` instruction is now interpreted as a no-base specifier
* Improve performance when exposing a large number of ports
#### Hack
+ Allow client-side only integration tests for Windows
* Include docker-py integration tests against Docker daemon as part of our test suites
#### Packaging
+ Support for the new version of the registry HTTP API
* Speed up `docker push` for images with a majority of already existing layers
- Fixed contacting a private registry through a proxy
#### Remote API
+ A new endpoint will stream live container resource metrics and can be accessed with the `docker stats` command
+ Containers can be renamed using the new `rename` endpoint and the associated `docker rename` command
* Container `inspect` endpoint show the ID of `exec` commands running in this container
* Container `inspect` endpoint show the number of times Docker auto-restarted the container
* New types of event can be streamed by the `events` endpoint: ‘OOM’ (container died with out of memory), ‘exec_create’, and ‘exec_start'
- Fixed returned string fields which hold numeric characters incorrectly omitting surrounding double quotes
#### Runtime
+ Docker daemon has full IPv6 support
+ The `docker run` command can take the `--pid=host` flag to use the host PID namespace, which makes it possible for example to debug host processes using containerized debugging tools
+ The `docker run` command can take the `--read-only` flag to make the container’s root filesystem mounted as readonly, which can be used in combination with volumes to force a container’s processes to only write to locations that will be persisted
+ Container total memory usage can be limited for `docker run` using the `—memory-swap` flag
* Major stability improvements for devicemapper storage driver
* Better integration with host system: containers will reflect changes to the host's `/etc/resolv.conf` file when restarted
* Better integration with host system: per-container iptable rules are moved to the DOCKER chain
- Fixed container exiting on out of memory to return an invalid exit code
#### Other
* The HTTP_PROXY, HTTPS_PROXY, and NO_PROXY environment variables are properly taken into account by the client when connecting to the Docker daemon
## 1.4.1 (2014-12-15)
#### Runtime
- Fix issue with volumes-from and bind mounts not being honored after create
## 1.4.0 (2014-12-11)
#### Notable Features since 1.3.0
+ Set key=value labels to the daemon (displayed in `docker info`), applied with
new `-label` daemon flag
+ Add support for `ENV` in Dockerfile of the form:
`ENV name=value name2=value2...`
+ New Overlayfs Storage Driver
+ `docker info` now returns an `ID` and `Name` field
+ Filter events by event name, container, or image
+ `docker cp` now supports copying from container volumes
- Fixed `docker tag`, so it honors `--force` when overriding a tag for existing
image.
## 1.3.3 (2014-12-11)
#### Security
- Fix path traversal vulnerability in processing of absolute symbolic links (CVE-2014-9356)
