renovate[bot]	0695424f7d	fix(deps): update module google.golang.org/grpc [security] (main) (#11031 ) [![Mend Renovate](https://app.renovatebot.com/images/banner.svg)](https://renovatebot.com) This PR contains the following updates: \| Package \| Type \| Update \| Change \| \|---\|---\|---\|---\| \| [google.golang.org/grpc](https://togithub.com/grpc/grpc-go) \| require \| minor \| `v1.53.0` -> `v1.56.3` \| \| [google.golang.org/grpc](https://togithub.com/grpc/grpc-go) \| require \| patch \| `v1.58.2` -> `v1.58.3` \| ### GitHub Vulnerability Alerts #### [GHSA-m425-mq94-257g](https://togithub.com/grpc/grpc-go/security/advisories/GHSA-m425-mq94-257g) ### Impact In affected releases of gRPC-Go, it is possible for an attacker to send HTTP/2 requests, cancel them, and send subsequent requests, which is valid by the HTTP/2 protocol, but would cause the gRPC-Go server to launch more concurrent method handlers than the configured maximum stream limit. ### Patches This vulnerability was addressed by #6703 and has been included in patch releases: 1.56.3, 1.57.1, 1.58.3. It is also included in the latest release, 1.59.0. Along with applying the patch, users should also ensure they are using the `grpc.MaxConcurrentStreams` server option to apply a limit to the server's resources used for any single connection. ### Workarounds None. ### References #6703 --- ### Release Notes <details> <summary>grpc/grpc-go (google.golang.org/grpc)</summary> ### [`v1.56.3`](https://togithub.com/grpc/grpc-go/releases/tag/v1.56.3): Release 1.56.3 [Compare Source](https://togithub.com/grpc/grpc-go/compare/v1.56.2...v1.56.3) ### Security - server: prohibit more than MaxConcurrentStreams handlers from running at once (CVE-2023-44487) In addition to this change, applications should ensure they do not leave running tasks behind related to the RPC before returning from method handlers, or should enforce appropriate limits on any such work. ### [`v1.56.2`](https://togithub.com/grpc/grpc-go/releases/tag/v1.56.2): Release 1.56.2 [Compare Source](https://togithub.com/grpc/grpc-go/compare/v1.56.1...v1.56.2) - status: To fix a panic, `status.FromError` now returns an error with `codes.Unknown` when the error implements the `GRPCStatus()` method, and calling `GRPCStatus()` returns `nil`.

Salva Corts	52a3f16039	Flag categorize labels on streams response (#10419 ) We recently introduced support for ingesting and querying structured metadata in Loki. This adds a new dimension to Loki's labels since now we arguably have three categories of labels: _stream_, _structured metadata_, and _parsed_ labels. Depending on the origin of the labels, they should be used in LogQL expressions differently to achieve optimal performance. _stream_ labels should be added to stream matchers, _structured metadata_ labels should be used in a filter expression before any parsing expression, and _parsed_ labels should be placed after the parser expression extracting them. The Grafana UI has a hard time dealing with this same problem. Before https://github.com/grafana/grafana/pull/73955, the filtering functionality in Grafana was broken since it was not able to distinguish between _stream_ and _structured metadata_ labels. Also, as soon as a parser expression was added to the query, filters added by Grafana would be appended to the end of the query regardless of the label category. The PR above implements a workaround for this problem but needs a better API on Loki's end to mitigate all corner cases. Loki currently returns the following JSON for log queries: ```json ... { "stream": { "cluster": "us-central", "container": "query-frontend", "namespace": "loki", "level": "info", "traceID": "68810cf0c94bfcca" }, "values": [ [ "1693996529000222496", "1693996529000222496 aaaaaaaaa.....\n" ], ... }, { "stream": { "cluster": "us-central", "container": "query-frontend", "namespace": "loki", "level": "debug", "traceID": "a7116cj54c4bjz8s" }, "values": [ [ "1693996529000222497", "1693996529000222497 bbbbbbbbb.....\n" ], ... }, ... ``` As can be seen, there is no way we can distinguish the category of each label. This PR introduces a new flag `X-Loki-Response-Encoding-Flags: categorize-labels` that makes Loki return categorized labels as follows: ```json ... { "stream": { "cluster": "us-central", "container": "query-frontend", "namespace": "loki", }, "values": [ [ "1693996529000222496", "1693996529000222496 aaaaaaaaa.....\n", { "structuredMetadata": { "traceID": "68810cf0c94bfcca" }, "parsed": { "level": "info" } } ], [ "1693996529000222497", "1693996529000222497 bbbbbbbbb.....\n", { "structuredMetadata": { "traceID": "a7116cj54c4bjz8s" }, "parsed": { "level": "debug" } } ], ... }, ... ``` Note that this PR only supports log queries, not metric queries. From a UX perspective, being able to categorize labels in metric queries doesn't have any benefit yet. Having said that, supporting this for metric queries would require some minor refactoring on top of what has been implemented here. If we decide to do that, I think we should do it on a separate PR to avoid making this PR even larger. I also decided to leave out support for Tail queries to avoid making this PR even larger. Once this one gets merged, we can work to support tailing. --- Note to reviewers This PR is huge since we need to forward categorized all over the codebase (from parsing logs all the way to marshaling), fortunately, many of the changes come from updating tests and refactoring iterators. Tested out in a dev cell with query `'{stream="stdout"} \| label_format new="text"`. - Without the new flag: ``` $ http http://127.0.0.1:3100/loki/api/v1/query_range\?direction\=BACKWARD\&end\=1693996529322486000\&limit\=30\&query\=%7Bstream%3D%22stdout%22%7D+%7C+label_format+new%3D%22text%22\&start\=1693992929322486000 X-Scope-Orgid:REDACTED { "data": { "result": [ { "stream": { "new": "text", "pod": "loki-canary-986bd6f4b-xqmb7", "stream": "stdout" }, "values": [ [ "1693996529000222496", "1693996529000222496 pppppppppppp...\n" ], [ "1693996528499160852", "1693996528499160852 pppppppppppp...\n" ], ... ``` - With the new flag ``` $ http http://127.0.0.1:3100/loki/api/v1/query_range\?direction\=BACKWARD\&end\=1693996529322486000\&limit\=30\&query\=%7Bstream%3D%22stdout%22%7D+%7C+label_format+new%3D%22text%22\&start\=1693992929322486000 X-Scope-Orgid:REDACTED X-Loki-Response-Encoding-Flags:categorize-labels { "data": { "encodingFlags": [ "categorize-labels" ], "result": [ { "stream": { "pod": "loki-canary-986bd6f4b-xqmb7", "stream": "stdout" }, "values": [ [ "1693996529000222496", "1693996529000222496 pppppppppppp...\n", { "parsed": { "new": "text" } } ], [ "1693996528499160852", "1693996528499160852 pppppppppppp...\n", { "parsed": { "new": "text" } } ], ... ```	2 years ago

While the total number of requests is bounded by the http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create a new request while the existing one is still executing. With the fix applied, HTTP/2 servers now bound the number of simultaneously executing handler goroutines to the stream concurrency limit (MaxConcurrentStreams). New requests arriving when at the limit (which can only happen after the client has reset an existing, in-flight request) will be queued until a handler exits. If the request queue grows too large, the server will terminate the connection. This issue is also fixed in golang.org/x/net/http2 for users manually configuring HTTP/2. The default stream concurrency limit is 250 streams (requests) per HTTP/2 connection. This value may be adjusted using the golang.org/x/net/http2 package; see the Server.MaxConcurrentStreams setting and the ConfigureServer function. #### [CVE-2023-44487](https://togithub.com/apple/swift-nio-http2/security/advisories/GHSA-qppj-fm5r-hxr3) swift-nio-http2 is vulnerable to a denial-of-service vulnerability in which a malicious client can create and then reset a large number of HTTP/2 streams in a short period of time. This causes swift-nio-http2 to commit to a large amount of expensive work which it then throws away, including creating entirely new `Channel`s to serve the traffic. This can easily overwhelm an `EventLoop` and prevent it from making forward progress. swift-nio-http2 1.28 contains a remediation for this issue that applies reset counter using a sliding window. This constrains the number of stream resets that may occur in a given window of time. Clients violating this limit will have their connections torn down. This allows clients to continue to cancel streams for legitimate reasons, while constraining malicious actors. --- ### Configuration 📅 Schedule: Branch creation - "" (UTC), Automerge - At any time (no schedule defined). 🚦 Automerge: Disabled by config.

Arve Knudsen	489ca25bab	Upgrade to Prometheus@4b9c19fe5510 (#10843 ) What this PR does / why we need it: Upgrade to Prometheus@4b9c19fe5510. Since also golang.org/x/exp gets upgraded, calls to e.g. `slices.SortFunc` need updating (due to changed comparison function signature). I'm not aware of any functional changes from Prometheus (or otherwise), but please review carefully. Special notes for your reviewer: The Mimir team needs for Loki to be compatible with the latest Prometheus, so we can vendor mimir-prometheus@main into GEM. Checklist - [x] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (required) - [na] Documentation added - [x] Tests updated - [na] `CHANGELOG.md` updated - [ ] If the change is worth mentioning in the release notes, add `add-to-release-notes` label - [na] Changes that require user attention or interaction to upgrade are documented in `docs/sources/setup/upgrade/_index.md` - [na] For Helm chart changes bump the Helm chart version in `production/helm/loki/Chart.yaml` and update `production/helm/loki/CHANGELOG.md` and `production/helm/loki/README.md`.

Charles Korn	bde65667f7	Upgrade dskit to use packages migrated from weaveworks/common (#10164 ) What this PR does / why we need it: This PR upgrades dskit and replaces use of packages from weaveworks/common with their migrated equivalents in dskit. See https://github.com/grafana/dskit/pull/342 for more details. Note that Loki still uses some packages from weaveworks/common that I haven't migrated (`aws` and `test`) - I'll migrate these separately. If this PR needs to be rebuilt, I used `rewrite.sh` ([source](https://gist.github.com/charleskorn/48efe62a09d6d70f3de30327003df5c5#file-rewrite-sh)) to generate most of these changes.

Salva Corts	15af77ba83	Remove Prometheus dependency for push pkg (#9937 ) What this PR does / why we need it: In https://github.com/grafana/loki/pull/9694, we modified the `push` pkg to import Prometheus as a dependency to use the `labels.Labels` type for the entries' non-indexed labels. Having Prometheus as a dependency is problematic since any project importing the `push` pkg will need to import Prometheus as a result. In fact, this is one of the reasons why the `push` pkg was extracted from Loki in the first place (https://github.com/grafana/loki/pull/8259). This PR removes the dependency of Prometheus from the `push` pkg by copying some bits of the implementation for Prometheus' `labels.Labels`. We copy: - The Labels struct definition - The JSON Marshaling and Unmarshaling methods for the labels. We need this so labels are encoded as maps instead of an array of objects. --- Notes for reviewers: - To implement the JSON Marshaling and Unmarshaling methods the `push` pkg now depends on `golang.org/x/exp`. I think it should be fine for projects importing the `push` pkg to also depend on `golang.org/x/exp`, right?	3 years ago
Salva Corts	aae13c376d	Add metadata to push payload (#9694 ) What this PR does / why we need it: We are adding support for attaching labels to each log line. This is one of the series of the PRs broken up to make it easier to review changes. This PR updates the push payload to send labels with each log entry optionally. The log labels are supposed to be in the same format as the stream labels. Just to put it out, here is how it would look for proto and json push payload with same data: proto(`endpoint`: `(/loki/api/v1/push\|/api/prom/push)`, `Content-Type`: `application/x-protobuf`)(payload built using [push.Stream](`4cd1246b88/pkg/push/types.go (L12)`)): ``` push.Stream{ Entries: []logproto.Entry{ { Timestamp: time.Unix(0, 1688515200000000000), Line: "log line", Labels: `{foo="bar"}`, }, }, Labels: `{app="test"}`, } ``` v1(`endpoint`: `/loki/api/v1/push`, `Content-Type`: `application/json`): ```json { "streams": [{ "stream": { "app": "test" }, "values": [ ["1688515200000000000", "log line", { "foo": "bar" }] ] }] } ``` legacy-json(`/api/prom/push`, `Content-Type`: `application/json`): ```json { "streams": [{ "labels": "{app=\"test\"}", "entries": [{ "ts": "2023-07-05T00:00:00.000000000Z", "line": "log line", "labels": "{foo=\"bar\"}" }] }] } ``` Which issue(s) this PR fixes: Special notes for your reviewer: We may need to add more thoughtful tests.
