9d1552a54e fix IAM role retrieval from IMDSv2 
AWS IMDSv2 support was added in #1462, but the implementation did not
cover the addional IMDS access that occurs with the iam_role=auto
configuration.  This change implements IMDSv2 support for the IMDS
call to determine the instance's role name.

Set CURLOPT_UNRESTRICTED_AUTH when authenticating (#1681) 
This is necessary for authentication to work with AWS when it responds with 307 to the check bucket request when mounting. This happens to newly created buckets according to https://aws.amazon.com/premiumsupport/knowledge-center/s3-http-307-response/.

Prior to this, curl would follow the redirect, but would not include the `Authorization` header which would end up with `404`.

d96a08d4ad fixup! Implement AWS IMDSv2 support 2020-11-07 14:48:52 +09:00
Noah Meyerhans
f2f930300a Implement AWS IMDSv2 support 
AWS IMDSv2 is a session oriented method for retrieving instance metadata,
including IAM credentials, in Amazon EC2.  It is enabled by default in
non-enforcing mode in AWS (meaning it retains backwards compatibility with
existing IMDSv1 clients), but can be switched to enforcing mode, in which
clients are required to return API tokens with requests.

With this change, we implement support for IMDSv2 and enable it by default when
IAM roles are our source for authentication credentials.  In the event that
s3fs is running in cloud environment offering an IMDSv1-compatible API, we
support graceful fallback to that mode.  It can also be selected explicitly via
the imdsv1only mount option.

More details on IMDSv2 are available at
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instancedata-data-retrieval.html
and
https://aws.amazon.com/blogs/security/defense-in-depth-open-firewalls-reverse-proxies-ssrf-vulnerabilities-ec2-instance-metadata-service/
