This patch:
- Combines the shellcheck and lint stages. Free CircleCI plans allow a maximum
of 4 concurrent jobs, and from the timing, the "lint" and "shellcheck" stages
combined would still take less time than the other stages, so combining them
keeps the same overall duration, but saving one machine "slot".
- Splits some steps, so that their output can be found more easily in the CI
results. For example, separating building of Docker images from running them.
- Adds a "Docker info" step, because information about the environment can be
useful when debugging.
- Adds the "Docker info" and "Docker version" steps to all stages, so that it's
possible to get that information without having to find the stage in which
it's printed.

The configuration abused "Exclude" to exclude file-paths by filtering
on the output, however, the `Skip` option was designed for that, whereas
`Exclude` is for matching warnings.
An explicit "Skip" was added for "vendor", because even though the vendor
directory should already be ignored by the linter, in some situations,
it still seemed to warn on issues, so let's explicitly ignore it.

[security] Go 1.13.2 and Go 1.12.11 are released
Hi gophers,
We have just released Go 1.13.2 and Go 1.12.11 to address a recently reported
security issue. We recommend that all affected users update to one of these
releases (if you're not sure which, choose Go 1.13.2).
Invalid DSA public keys can cause a panic in dsa.Verify. In particular, using
crypto/x509.Verify on a crafted X.509 certificate chain can lead to a panic,
even if the certificates don't chain to a trusted root. The chain can be
delivered via a crypto/tls connection to a client, or to a server that accepts
and verifies client certificates. net/http clients can be made to crash by an
HTTPS server, while net/http servers that accept client certificates will
recover the panic and are unaffected.
Moreover, an application might crash invoking
crypto/x509.(*CertificateRequest).CheckSignature on an X.509 certificate
request, parsing a golang.org/x/crypto/openpgp Entity, or during a
golang.org/x/crypto/otr conversation. Finally, a golang.org/x/crypto/ssh client
can panic due to a malformed host key, while a server could panic if either
PublicKeyCallback accepts a malformed public key, or if IsUserAuthority accepts
a certificate with a malformed public key.
The issue is CVE-2019-17596 and Go issue golang.org/issue/34960.
Thanks to Daniel Mandragona for discovering and reporting this issue. We'd also
like to thank regilero for a previous disclosure of CVE-2019-16276.

In c2626a82 homedir logic got extremely simplified to only
checking HOME environment variable on UNIX systems.
Although this should work well enough in traditional environments,
this could break minimal containerized environments.
This patch reverts to using github.com/docker/docker/pkg/homedir
that was recently updated to have less dependencies.

Hi gophers,
We have just released Go 1.13.1 and Go 1.12.10 to address a recently reported security issue. We recommend that all affected users update to one of these releases (if you're not sure which, choose Go 1.13.1).
net/http (through net/textproto) used to accept and normalize invalid HTTP/1.1 headers with a space before the colon, in violation of RFC 7230. If a Go server is used behind an uncommon reverse proxy that accepts and forwards but doesn't normalize such invalid headers, the reverse proxy and the server can interpret the headers differently. This can lead to filter bypasses or request smuggling, the latter if requests from separate clients are multiplexed onto the same upstream connection by the proxy. Such invalid headers are now rejected by Go servers, and passed without normalization to Go client applications.
The issue is CVE-2019-16276 and Go issue golang.org/issue/34540.
Thanks to Andrew Stucki, Adam Scarr (99designs.com), and Jan Masarik (masarik.sh) for discovering and reporting this issue.
Downloads are available at https://golang.org/dl for all supported platforms.
Alla prossima,
Filippo on behalf of the Go team
```
From the patch: 6e6f4aaf70
```
net/textproto: don't normalize headers with spaces before the colon
RFC 7230 is clear about headers with a space before the colon, like
X-Answer : 42
being invalid, but we've been accepting and normalizing them for compatibility
purposes since CL 5690059 in 2012.
On the client side, this is harmless and indeed most browsers behave the same
to this day. On the server side, this becomes a security issue when the
behavior doesn't match that of a reverse proxy sitting in front of the server.
For example, if a WAF accepts them without normalizing them, it might be
possible to bypass its filters, because the Go server would interpret the
header differently. Worse, if the reverse proxy coalesces requests onto a
single HTTP/1.1 connection to a Go server, the understanding of the request
boundaries can get out of sync between them, allowing an attacker to tack an
arbitrary method and path onto a request by other clients, including
authentication headers unknown to the attacker.
This was recently presented at multiple security conferences:
https://portswigger.net/blog/http-desync-attacks-request-smuggling-reborn
net/http servers already reject header keys with invalid characters.
Simply stop normalizing extra spaces in net/textproto, let it return them
unchanged like it does for other invalid headers, and let net/http enforce
RFC 7230, which is HTTP specific. This loses us normalization on the client
side, but there's no right answer on the client side anyway, and hiding the
issue sounds worse than letting the application decide.
