Keys are helpful to ensure the strict ordering of messages, however currently the
code uses a random request id for every log, hence using the request-id
as a Kafka key is not serve any purpose;
This commit removes the usage of the key, to also fix the audit issue from
internal subsystem that does not have a request ID.
Send() is synchronous and can affect the latency of S3 requests when the
logger buffer is full.
Avoid checking if the HTTP target is online or not and increase the
workers anyway since the buffer is already full.
Also, avoid logs flooding when the audit target is down.
This change adds a `Secret` property to `HelpKV` to identify secrets
like passwords and auth tokens that should not be revealed by the server
in its configuration fetching APIs. Configuration reporting APIs now do
not return secrets.
A lot of warning messages are printed in CI/CD failures generated by go
test. Avoid that by requiring at least Error level for logging when
doing go test.
fixes#15334
- re-use net/url parsed value for http.Request{}
- remove gosimple, structcheck and unusued due to https://github.com/golangci/golangci-lint/issues/2649
- unwrapErrs upto leafErr to ensure that we store exactly the correct errors
Rename Trigger -> Event to be a more appropriate
name for the audit event.
Bonus: fixes a bug in AddMRFWorker() it did not
cancel the waitgroup, leading to waitgroup leaks.
it is not safe to pass around sync.Map
through pointers, as it may be concurrently
updated by different callers.
this PR simplifies by avoiding sync.Map
altogether, we do not need sync.Map
to keep object->erasureMap association.
This PR fixes a crash when concurrently
using this value when audit logs are
configured.

It would seem like the PR #11623 had chewed more
than it wanted to, non-fips build shouldn't really
be forced to use slower crypto/sha256 even for
presumed "non-performance" codepaths. In MinIO
there are really no "non-performance" codepaths.
This assumption seems to have had an adverse
effect in certain areas of CPU usage.
This PR ensures that we stick to sha256-simd
on all non-FIPS builds, our most common build
to ensure we get the best out of the CPU at
any given point in time.
When configuring a new target, such as an audit target, the server waits
until all audit events are sent to the audit target before doing the
swap from the old to the new audit target. Therefore current S3 operations
can suffer from this since the audit swap lock will be held.
This behavior is unnecessary as the new audit target can enter in a
functional mode immediately and the old audit will just cancel itself
at its own pace.
This PR simplifies few things by splitting
the locks between audit, logger targets to
avoid potential contention between them.
any failures inside audit/logger HTTP
targets must only log to console instead
of other targets to avoid cyclical dependency.
avoids unneeded atomic variables instead
uses RWLock to differentiate a more common
read phase v/s lock phase.
Fix `panic: "POST /minio/peer/v21/signalservice?signal=2": sync: WaitGroup is reused before previous Wait has returned`
Log entries already on the channel would cause `logEntry` to increment the
waitgroup when sending messages, after Cancel has been called.
Instead of tracking every single message, just check the send goroutine. Faster
and safe, since it will not decrement until the channel is closed.
Regression from #14289
PR introduced in #13819 was incorrect and was not
handling the situation where a buffer is full can
cause incessant amount of logs that would keep the
logger webhook overrun by the requests.
To avoid this only log failures to console logger
instead of all targets as it can cause self reference,
leading to an infinite loop.
When setting a config of a particular sub-system, validate the existing
config and notification targets of only that sub-system, so that
existing errors related to one sub-system (e.g. notification target
offline) do not result in errors for other sub-systems.
time.Format() is not necessary prematurely for JSON
marshalling, since JSON marshalling indeed defaults
to RFC3339Nano.
This also ensures the 'time' is remembered until its
logged and it is the same time when the 'caller'
invoked 'log' functions.
Also log all the missed events and logs instead of silently
swallowing the events.
Bonus: Extend the logger webhook to support mTLS
similar to audit webhook target.
- remove some duplicated code
- reported a bug, separately fixed in #13664
- using strings.ReplaceAll() when needed
- using filepath.ToSlash() use when needed
- remove all non-Go style comments from the codebase

Logger targets were not race protected against concurrent updates from for example `HTTPConsoleLoggerSys`.
Restrict direct access to targets and make slices immutable so a returned slice can be processed safely without locks.
auditLog should be attempted right before the
return of the function and not multiple times
per function, this ensures that we only trigger
it once per function call.
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`
