DNS refresh() in-case of MinIO can safely re-use
the previous values on bare-metal setups, since
bare-metal arrangements do not change DNS in any
manner commonly.
This PR simplifies that, we only ever need DNS caching
on bare-metal setups.
- On containerized setups do not enable DNS
caching at all, as it may have adverse effects on
the overall effectiveness of k8s DNS systems.
k8s DNS systems are dynamic and expect applications
to avoid managing DNS caching themselves, instead
provide a cleaner container native caching
implementations that must be used.
- update IsDocker() detection, including podman runtime
- move to minio/dnscache fork for a simpler package
It is possible for anyone with admin access to relatively
to get any content of any random OS location by simply
providing the file with 'mc admin update alias/ /etc/passwd`.
Workaround is to disable 'admin:ServiceUpdate' action. Everyone
is advised to upgrade to this patch.
Thanks to @alevsk for finding this bug.
Currently, if one server in a distributed setup fails to upgrade
due to any reasons, it is not possible to upgrade again unless
nodes are restarted.
To fix this, split the upgrade process into two steps :
- download the new binary on all servers
- If successful, overwrite the old binary with the new one
It is wasteful to allow parallel upgrades of MinIO server. This also generates
weird error invoked by selfupdate module when it happens such as:
'rename /opt/bin/.minio.old /opt/bin/..minio.old.old'
startup speed-up, currently getFormatErasureInQuorum()
would spend up to 2-3secs when there are 3000+ drives
for example in a setup, simplify this implementation
to use drive counts.
This is to ensure that there are no projects
that try to import `minio/minio/pkg` into
their own repo. Any such common packages should
go to `https://github.com/minio/pkg`
This code is necessary for `mc admin update` command
to work with fips compiled binaries, with fips tags
the releaseInfo will automatically point to fips
specific binaries.
This commit replaces the usage of
github.com/minio/sha256-simd with crypto/sha256
of the standard library in all non-performance
critical paths.
This is necessary for FIPS 140-2 compliance which
requires that all crypto. primitives are implemented
by a FIPS-validated module.
Go can use the Google FIPS module. The boringcrypto
branch of the Go standard library uses the BoringSSL
FIPS module to implement crypto. primitives like AES
or SHA256.
We only keep github.com/minio/sha256-simd when computing
the content-SHA256 of an object. Therefore, this commit
relies on a build tag `fips`.
When MinIO is compiled without the `fips` flag it will
use github.com/minio/sha256-simd. When MinIO is compiled
with the fips flag (go build --tags "fips") then MinIO
uses crypto/sha256 to compute the content-SHA256.

etcd v3.5.0 will now have a properly imported versioned path
this fixes our pending migration to newer repo
Changes in IP underneath are dynamic in replica sets
with multiple tenants, so deploying in that fashion
will not work until we wait for atleast one participatory
server to be local.
This PR also ensures that multi-tenant zone expansion also
works in replica set k8s deployments.
Introduces a new ENV `KUBERNETES_REPLICA_SET` check to call
appropriate code paths.
In replica sets, hosts resolve to localhost
IP automatically until the deployment fully
comes up. To avoid this issue we need to
wait for such resolution.
This change is related to larger config migration PR
change, this is a first stage change to move our
configs to `cmd/config/` - divided into its subsystems
