When connecting with the daemon using a UNIX socket, the HTTP hostname was set, based
on the socket location, which was generating some noise in the test-logs.
Given that the actual hostname is not important (the URL just has to be well-formed),
the hostname/address can be cleaned up to reduce the noise.
This patch strips the path from the `addr`, and keeps `<random-id>.sock` as address.

11:59:47 health_test.go:57: assertion failed: error is not nil: Error response from daemon: Invalid signal: SIGUSR1
``
That test was added recently in https://github.com/moby/moby/pull/39454, but
rewritten in a commit in the same PR:
f8aef6a92f
In that rewrite, there were some changes:
- originally it was skipped on Windows, but the rewritten test doesn't have that skip:
```go
testRequires(c, DaemonIsLinux) // busybox doesn't work on Windows
```
- the original test used `SIGINT`, but the new one uses `SIGUSR1`
Analysis:
- The Error bubbles up from: 8e610b2b55/pkg/signal/signal.go (L29-L44)
- Interestingly; `ContainerKill` should validate if a signal is valid for the given platform, but somehow we don't hit that part; f1b5612f20/daemon/kill.go (L40-L48)
- Windows only looks to support 2 signals currently 8e610b2b55/pkg/signal/signal_windows.go (L17-L26)
- Upstream Golang looks to define `SIGINT` as well; 77f9b2728e/src/runtime/defs_windows.go (L44)
- This looks like the current list of Signals upstream in Go; 3b58ed4ad3/windows/types_windows.go (L52-L67)

go1.12.8 (released 2019/08/13) includes security fixes to the net/http and net/url packages.
See the Go 1.12.8 milestone on our issue tracker for details:
https://github.com/golang/go/issues?q=milestone%3AGo1.12.8
- net/http: Denial of Service vulnerabilities in the HTTP/2 implementation
net/http and golang.org/x/net/http2 servers that accept direct connections from untrusted
clients could be remotely made to allocate an unlimited amount of memory, until the program
crashes. Servers will now close connections if the send queue accumulates too many control
messages.
The issues are CVE-2019-9512 and CVE-2019-9514, and Go issue golang.org/issue/33606.
Thanks to Jonathan Looney from Netflix for discovering and reporting these issues.
This is also fixed in version v0.0.0-20190813141303-74dc4d7220e7 of golang.org/x/net/http2.
net/url: parsing validation issue
- url.Parse would accept URLs with malformed hosts, such that the Host field could have arbitrary
suffixes that would appear in neither Hostname() nor Port(), allowing authorization bypasses
in certain applications. Note that URLs with invalid, not numeric ports will now return an error
from url.Parse.
The issue is CVE-2019-14809 and Go issue golang.org/issue/29098.

From the first glance, `docker logs --tail 0` does not make sense,
as it is supposed to produce no output, but `tail -n 0` from GNU
coreutils is working like that, plus there is even a test case
(`TestLogsTail` in integration-cli/docker_cli_logs_test.go).
Now, something like `docker logs --follow --tail 0` makes total
sense, so let's make it work.

If we take a long time to process log messages, and during that time
journal file rotation occurs, the journald client library will keep
those rotated files open until sd_journal_process() is called.
By periodically calling sd_journal_process() during the processing
loop we shrink the window of time a client instance has open file
descriptors for rotated (deleted) journal files.
This code is modelled after that of journalctl [1]; the above explanation
as well as the value of 1024 is taken from there.

TL;DR: simplify the code, fix --follow hanging indefinitely
Do the following to simplify the followJournal() code:
1. Use Go-native select instead of C-native polling.
2. Use Watch{Producer,Consumer}Gone(), eliminating the need
to have journald.closed variable, and an extra goroutine.
3. Use sd_journal_wait(). In the words of its own man page:
> A synchronous alternative for using sd_journal_get_fd(),
> sd_journal_get_events(), sd_journal_get_timeout() and
> sd_journal_process() is sd_journal_wait().
Unfortunately, the logic is still not as simple as it
could be; the reason being, once the container has exited,
journald might still be writing some logs from its internal
buffers onto journal file(s), and there is no way to
figure out whether it's done so we are guaranteed to
read all of it back. This bug can be reproduced with
something like
> $ ID=$(docker run -d busybox seq 1 150000); docker logs --follow $ID
> ...
> 128123
> $
(The last expected output line should be `150000`).
To avoid exiting from followJournal() early, add the
following logic: once the container is gone, keep trying
to drain the journal until there's no new data for at
least `waitTimeout` time period.

1. The journald client library initializes inotify watch(es)
during the first call to sd_journal_get_fd(), and it make sense
to open it earlier in order to not lose any journal file rotation
events.
2. It only makes sense to call this if we're going to use it
later on -- so add a check for config.Follow.
3. Remove the redundant call to sd_journal_get_fd().
NOTE that any subsequent calls to sd_journal_get_fd() return
the same file descriptor, so there's no real need to save it
for later use in wait_for_data_cancelable().

In case Tail=N parameter is requested, we need to show N lines.
It does not make sense to walk backwards one by one if we can

This fixes a regression introduced in 6d87f19142,
causing `COPY --from` to fail if the target directory does not exist:
```
FROM mcr.microsoft.com/windows/servercore:ltsc2019 as s1
RUN echo "Hello World" > /hello
FROM mcr.microsoft.com/windows/servercore:ltsc2019
COPY --from=s1 /hello /hello/another/world
```
Would produce an error:
```
Step 4/4 : COPY --from=s1 /hello /hello/another/world
failed to copy files: mkdir \\?: The filename, directory name, or volume label syntax is incorrect.
```
The cause for this was that Go's `os.MkdirAll()` does not support/detect volume GUID paths
(`\\?\Volume{dae8d3ac-b9a1-11e9-88eb-e8554b2ba1db}\hello\another}`), and as a result
attempted to create the volume as a directory (`\\?`), causing it to fail.
This patch replaces `os.MkdirAll()` with our own `system.MkdirAll()` function, which
is capable of detecting GUID volumes.

This check was used to make sure we don't bump Go versions independently
(Linux/Windows). The Dockerfile switched to using a build-arg to allow
overriding the Go version, which rendered this check non-functional.
It also fails if Linux versions use a specific variant of the image;

Commit 77b8465d7e added a secret update
endpoint to allow updating labels on existing secrets. However, when
implementing the endpoint, the DebugRequestMiddleware was not updated
to scrub the Data field (as is being done when creating a secret).
When updating a secret (to set labels), the Data field should be either
`nil` (not set), or contain the same value as the existing secret. In
situations where the Data field is set, and the `dockerd` daemon is
running with debugging enabled / log-level debug, the base64-encoded
value of the secret is printed to the daemon logs.
The docker cli does not have a `docker secret update` command, but
when using `docker stack deploy`, the docker cli sends the secret
data both when _creating_ a stack, and when _updating_ a stack, thus
leaking the secret data if the daemon runs with debug enabled:
1. Start the daemon in debug-mode
dockerd --debug
2. Initialize swarm
docker swarm init
3. Create a file containing a secret
echo secret > my_secret.txt
4. Create a docker-compose file using that secret
cat > docker-compose.yml <<'EOF'
version: "3.3"
services:
web:
image: nginx:alpine
secrets:
- my_secret
secrets:
my_secret:
file: ./my_secret.txt
EOF
5. Deploy the stack
docker stack deploy -c docker-compose.yml test
6. Verify that the secret is scrubbed in the daemon logs

7. Re-deploy the stack to trigger an "update"
docker stack deploy -c docker-compose.yml test
8. Notice that this time, the Data field is not scrubbed, and the base64-encoded secret is logged

This patch modifies `maskSecretKeys` to unconditionally scrub `Data` fields.
Currently, only the `secrets` and `configs` endpoints use a field with this
name, and no other POST API endpoints use a data field, so scrubbing this
field unconditionally will only scrub requests for those endpoints.
If a new endpoint is added in future where this field should not be scrubbed,
we can re-introduce more fine-grained (path-specific) handling.
This patch introduces some change in behavior:
- In addition to secrets, requests to create or update _configs_ will
now have their `Data` field scrubbed. Generally, the actual data should
not be interesting for debugging, so likely will not be problematic.
In addition, scrubbing this data for configs may actually be desirable,
because (even though they are not explicitely designed for this purpose)
configs may contain sensitive data (credentials inside a configuration
file, e.g.).
- Requests that send key/value pairs as a "map" and that contain a
key named "data", will see the value of that field scrubbed. This
means that (e.g.) setting a `label` named `data` on a config, will
scrub/mask the value of that label.
- Note that this is already the case for any label named `jointoken`,
`password`, `secret`, `signingcakey`, or `unlockkey`.

This reverts commit 98fc09128b in order to
keep registry v2 schema1 handling and libtrust-key-based engine ID.
Because registry v2 schema1 was not officially deprecated and
registries are still relying on it, this patch puts its logic back.
However, registry v1 relics are not added back since v1 logic has been
removed a while ago.
This also fixes an engine upgrade issue in a swarm cluster. It was relying
on the Engine ID to be the same upon upgrade, but the mentioned commit
modified the logic to use UUID and from a different file.
Since the libtrust key is always needed to support v2 schema1 pushes,
that the old engine ID is based on the libtrust key, and that the engine ID
needs to be conserved across upgrades, adding a UUID-based engine ID logic
seems to add more complexity than it solves the problems.
Hence reverting the engine ID changes as well.

Before 7a7357da, archive.TarResourceRebase was being used to copy files
and folders from the container. That function splits the source path
into a dirname + basename pair to support copying a file:
if you wanted to tar `dir/file` it would tar from `dir` the file `file`
(as part of the IncludedFiles option).
However, that path splitting logic was kept for folders as well, which
resulted in weird inputs to archive.TarWithOptions:
if you wanted to tar `dir1/dir2` it would tar from `dir1` the directory
`dir2` (as part of IncludedFiles option).
Although it was weird, it worked fine until we started chrooting into
the container rootfs when doing a `docker cp` with container source set
to `/` (cf 3029e765).
The fix is to only do the path splitting logic if the source is a file.
Unfortunately, 7a7357da added support for LCOW by duplicating some of
this subtle logic. Ideally we would need to do more refactoring of the
archive codebase to properly encapsulate these behaviors behind well-
documented APIs.
This fix does not do that. Instead, it fixes the issue inline.

Moby currently sorts uid and gid ranges in id maps. This causes subuid
and subgid files to be interpreted wrongly.
The subuid file
```
> cat /etc/subuid
jonas:100000:1000
jonas:1000:1
```
configures that the container uids 0-999 are mapped to the host uids
100000-100999 and uid 1000 in the container is mapped to uid 1000 on the
host. The expected uid_map is:
```
> docker run ubuntu cat /proc/self/uid_map
0 100000 1000
1000 1000 1
```
Moby currently sorts the ranges by the first id in the range. Therefore
with the subuid file above the uid 0 in the container is mapped to uid
100000 on host and the uids 1-1000 in container are mapped to the uids
1-1000 on the host. The resulting uid_map is:
```
> docker run ubuntu cat /proc/self/uid_map
0 1000 1
1 100000 1000
```
The ordering was implemented to work around a limitation in Linux 3.8.
This is fixed since Linux 3.9 as stated on the user namespaces manpage
[1]:
> In the initial implementation (Linux 3.8), this requirement was
> satisfied by a simplistic implementation that imposed the further
> requirement that the values in both field 1 and field 2 of successive
> lines must be in ascending numerical order, which prevented some
> otherwise valid maps from being created. Linux 3.9 and later fix this
> limitation, allowing any valid set of nonoverlapping maps.
This fix changes the interpretation of subuid and subgid files which do
not have the ids of in the numerical order for each individual user.
This breaks users that rely on the current behaviour.
The desired mapping above - map low user ids in the container to high
user ids on the host and some higher user ids in the container to lower
user on host - can unfortunately not archived with the current
behaviour.

Running a bundled aufs benchmark sometimes results in this warning:
> WARN[0001] Couldn't run auplink before unmount /tmp/aufs-tests/aufs/mnt/XXXXX error="exit status 22" storage-driver=aufs
If we take a look at what aulink utility produces on stderr, we'll see:
> auplink:proc_mnt.c:96: /tmp/aufs-tests/aufs/mnt/XXXXX: Invalid argument
and auplink exits with exit code of 22 (EINVAL).
Looking into auplink source code, what happens is it tries to find a
record in /proc/self/mounts corresponding to the mount point (by using
setmntent()/getmntent_r() glibc functions), and it fails.
Some manual testing, as well as runtime testing with lots of printf
added on mount/unmount, as well as calls to check the superblock fs
magic on mount point (as in graphdriver.Mounted(graphdriver.FsMagicAufs, target)
confirmed that this record is in fact there, but sometimes auplink
can't find it. I was also able to reproduce the same error (inability
to find a mount in /proc/self/mounts that should definitely be there)
using a small C program, mocking what `auplink` does:
```c
#include <stdio.h>
#include <err.h>
#include <mntent.h>
#include <string.h>
#include <stdlib.h>
int main(int argc, char **argv)
{
FILE *fp;
struct mntent m, *p;
char a[4096];
char buf[4096 + 1024];
int found =0, lines = 0;
if (argc != 2) {
fprintf(stderr, "Usage: %s <mountpoint>\n", argv[0]);
exit(1);
}
fp = setmntent("/proc/self/mounts", "r");
if (!fp) {
err(1, "setmntent");
}
setvbuf(fp, a, _IOLBF, sizeof(a));
while ((p = getmntent_r(fp, &m, buf, sizeof(buf)))) {
lines++;
if (!strcmp(p->mnt_dir, argv[1])) {
found++;
}
}
printf("found %d entries for %s (%d lines seen)\n", found, argv[1], lines);
return !found;
}
```
I have also wrote a few other C proggies -- one that reads
/proc/self/mounts directly, one that reads /proc/self/mountinfo instead.
They are also prone to the same occasional error.
It is not perfectly clear why this happens, but so far my best theory
is when a lot of mounts/unmounts happen in parallel with reading
contents of /proc/self/mounts, sometimes the kernel fails to provide
continuity (i.e. it skips some part of file or mixes it up in some
other way). In other words, this is a kernel bug (which is probably
hard to fix unless some other interface to get a mount entry is added).
Now, there is no real fix, and a workaround I was able to come up
with is to retry when we got EINVAL. It usually works on the second
attempt, although I've once seen it took two attempts to go through.

Do not use filepath.Walk() as there's no requirement to recursively
go into every directory under mnt -- a (non-recursive) list of
directories in mnt is sufficient.
With filepath.Walk(), in case some container will fail to unmount,
it'll go through the whole container filesystem which is both
excessive and useless.
This is similar to commit f1a4592297 ("devmapper.shutdown:
optimize")
While at it, raise the priority of "unmount error" message from debug
to a warning. Note we don't have to explicitly add `m` as unmount error (from
pkg/mount) will have it.

In case there are a big number of layers, so that mount data won't fit
into a single memory page (4096 bytes on most platforms, which is good
enough for about 40 layers, depending on how long graphdriver root path
is), we supply additional layers with O_REMOUNT, as described in aufs
documentation.
Problem is, the current implementation does that one layer at a time
(i.e. there is one mount syscall per each additional layer).
Optimize the code to supply as many layers as we can fit in one page
(basically reusing the same code as for the original mount).
Note, per aufs docs, "[a]t remount-time, the options are interpreted
in the given order, e.g. left to right" so we should be good.
Tested on an image with ~100 layers.

As pointed out by Tonis, there's a race between ReleaseRWLayer()
and GetRWLayer():
```
----- goroutine 1 ----- ----- goroutine 2 -----
ReleaseRWLayer()
m := ls.mounts[l.Name()]
...
m.deleteReference(l)
m.hasReferences()
... GetRWLayer()
... mount := ls.mounts[id]
ls.driver.Remove(m.mountID)
ls.store.RemoveMount(m.name) return mount.getReference()
delete(ls.mounts, m.Name())
----------------------- -----------------------
```
When something like this happens, GetRWLayer will return
an RWLayer without a storage. Oops.
There might be more races like this, and it seems the best
solution is to lock by layer id/name by using pkg/locker.
With this in place, name collision could not happen, so remove
the part of previous commit that protected against it in
CreateRWLayer (temporary nil assigmment and associated rollback).
So, now we have
* layerStore.mountL sync.Mutex to protect layerStore.mount map[]
(against concurrent access);
* mountedLayer's embedded `sync.Mutex` to protect its references map[];

This test is dependent on the search results returned by Docker Hub, which
can change at any moment, and causes this test to be unpredictable.
Removing this test instead of trying to catch up with Docker Hub any time
the results change, because it's effectively testing Docker Hub, and not
the daemon.
Unit tests are already in place to test the core functionality of the daemon,
so it should be safe to remove this test.

Sometimes this test fails (allegedly due to problems with Docker Hub),
but it fails later than it should, for example:
> 01:20:34.845 assertion failed: expression is false: strings.Count(outSearchCmdStars, "[OK]") <= strings.Count(outSearchCmd, "[OK]"): The quantity of images with stars should be less than that of all images: <...>
This, with non-empty list of images following, means that the initial
`docker search busybox` command returned not enough results. So, add
a check that `docker search busybox` returns something.
While at it,
* raise the number of stars to 10;
* simplify check for number of lines (no need to count [OK]'s);

As of Go 1.12, the `testing` package panics if a goroutine logs to a
`testing.T` after the relevant test has completed. This was not
documented as a change at all; see the commit
95d06ab6c982f58b127b14a52c3325acf0bd3926 in the Go repository for the
relevant change.
At any point in the integration tests, tests could panic with the
message "Log in goroutine after TEST_FUNCTION has completed". This was
exacerbated by less direct logging I/O, e.g. running `make test` with
its output piped instead of attached to a TTY.
The most common cause of panics was that there was a race condition
between an exit logging goroutine and the `StopWithError` method:
`StopWithError` could return, causing the calling test method to return,
causing the `testing.T` to be marked as finished, before the goroutine
could log that the test daemon had exited. The fix is simple: capture
the result of `cmd.Wait()`, _then_ log, _then_ send the captured
result over the `Wait` channel. This ensures that the message is
logged before `StopWithError` can return, blocking the test method
so that the target `testing.T` is not marked as finished.

The `--rootless` flag had a couple of issues:
* #38702: euid=0, $USER="root" but no access to cgroup ("rootful" Docker in rootless Docker)
* #39009: euid=0 but $USER="docker" (rootful boot2docker)
To fix#38702, XDG dirs are ignored as in rootful Docker, unless the
dockerd is directly running under RootlessKit namespaces.
RootlessKit detection is implemented by checking whether `$ROOTLESSKIT_STATE_DIR` is set.
To fix#39009, the non-robust `$USER` check is now completely removed.
The entire logic can be illustrated as follows:
```
withRootlessKit := getenv("ROOTLESSKIT_STATE_DIR")
rootlessMode := withRootlessKit || cliFlag("--rootless")
honorXDG := withRootlessKit
useRootlessKitDockerProxy := withRootlessKit
removeCgroupSpec := rootlessMode
adjustOOMScoreAdj := rootlessMode
