Different gateway implementations due to different backend
API errors, might return different unsupported errors at
our handler layer. Current code posed a problem for us because
this information was lost and we would convert it to InternalError
in this situation all S3 clients end up retrying the request.
To avoid this unexpected situation implement a way to support
this cleanly such that the underlying information is not lost
which is returned by gateway.
This commit fixes an AWS S3 incompatibility issue.
The AccessKeyID may contain one or more `/` which caused
the server to interpret parts of the AccessKeyID as
other `X-Amz-Credential` parameters (like date, region, ...)
This commit fixes this by allowing 5 or more
`X-Amz-Credential` parameter strings and only interpreting
the last 5.
Fixes#6443
This is a generic minimum value. The current reason is to support
Azure blob storage accounts name whose length is less than 5. 3 is the
minimum length for Azure.
This change replaces the non-constant time comparison of
request signatures with a constant time implementation. This
prevents a timing attack which can be used to learn a valid
signature for a request without knowing the secret key.
Fixes#5334
This is a consolidation effort, avoiding usage
of naked strings in codebase. Whenever possible
use constants which can be repurposed elsewhere.
This also fixes `goconst ./...` reported issues.
