Displaying mode and controls to additional participants (#46450)

* Displaying mode and controls to additional participants * Moving SessionControlsInfoBroadcast over to kube/proxy * Transitioning to consistent proxy-emitted mode+controls * Moving message broadcast so new participant wont see it * Possible unit test fix (cant seem to test locally) * Fixed unit test * Adding a line break before messaging the participant * Linter errors * Emitting audit event and controls message for additional parties, i.e. not the session initiator * Revert "Emitting audit event and controls message for additional parties, i.e. not the session initiator" This reverts commit b66ad27. * Add User Tasks resource - protos (#46059) * Add User Integration Tasks resource - protos * add account id * move state to task instead of instance * rename from user integration task to user task * add instance id * Add notice to web UI that users arent equal to MAU (#46686) This adds a dismissible notice to the Users page for usage based billing users that notifies them that the user count here isn't an accurate reflection of MAU * Clarify TLS requirements in the Jira guide (#46484) Closes #45654 - Indicate that certificates for the Jira web server cannot be self signed. - Remove references to Caddy and a `Certificate` resource, which were left over from an attempted change to this guide that was not fully completed. * Remove TXT record validation of custom DNS zones in VNet (#46709) * Remove TXT record validation from custom DNS zones * Remove mentions of TXT records from docs * Outline in the RFD why domain verification was dropped * Update rfd/0163-vnet.md Co-authored-by: Nic Klaassen <nic@goteleport.com> --------- Co-authored-by: Nic Klaassen <nic@goteleport.com> * docs: mention the --days flag when executing an audit log query (#45764) * Update access-monitoring.mdx Include the default date range in the CLI example. This range is otherwise unclear and is hidden in the tctl audit help menu. * Update access-monitoring.mdx * Update docs/pages/admin-guides/access-controls/access-monitoring.mdx Co-authored-by: Zac Bergquist <zac.bergquist@goteleport.com> --------- Co-authored-by: Zac Bergquist <zac.bergquist@goteleport.com> * Remove access-graph path resolution, proxy `/enterprise` requests (#46541) * Remove `access-graph` path from tsconfig * Proxy /enterprise requested in dev * update e ref (#46726) * fix: tolerate mismatched key PEM headers (#46725) * fix: tolerate mismatched key PEM headers Issue #43381 introduced a regression where we now fail to parse PKCS8 encoded RSA private keys within an "RSA PRIVATE KEY" PEM block in some cases. This format is somewhat non-standard, usually PKCS8 data should be in a "PRIVATE KEY" PEM block. However, certain versions of OpenSSL and possibly even Teleport in specific cases have generated private keys in this format. This commit updates ParsePrivateKey and ParsePublicKey to be more tolerant of PKCS8, PKCS1, or PKIX key data no matter which PEM header is used. Fixes #46710 changelog: fixed regression in private key parser to handle mismatched PEM headers * fix typo in comment Co-authored-by: Edoardo Spadolini <edoardo.spadolini@goteleport.com> --------- Co-authored-by: Edoardo Spadolini <edoardo.spadolini@goteleport.com> * Use dynamic base path for favicon images (#46719) * Add Datadog Incident Management plugin support (#46271) * Implement datadog plugin * Add unit tests * Add fallback recipient config * Rename to Datadog Incident Management * Update tests * Datadog Incident Management * Update tctl resource plugin command * Typos * Lint * Exclude api changes for now * Set channel size * Address feedback - Add PluginShutdownTimeout const - Support api endpoint configuration - Add additional godocs/comments * Comment about datadog client package * Document Datadog API types * Only post resolution message when the AR is resolved * Fix lint * Unused function --------- Co-authored-by: hugoShaka <hugo.hervieux@goteleport.com> * Add AutoUpdate Client/Cache implementation (#46661) * Add AutoUpdate Client/Cache implementation * CR changes * Add permission for proxy to access resources * Rename all occurrences auto update to camelcase * Remove auto update client wrapper * Drop AutoUpdateServiceClient helper Rename comments for consistency * User Tasks: services and clients implementation (#46131) This PR adds the implementation for the User Tasks: - services (backend+cache) - clients (API + tctl) - light validation to set up the path for later PRs * expanding testplan for host user creation (#46729) * Fix operator docs reference generator bug (#46732) In the reference page for one Kubernetes operator resource, some Markdown links are malformed. The issue is that some fields of custom resource definitions used by the operator consist of arrays of anonymous objects with fields that are also objects. When creating docs based on these fields, the operator resource docs generator creates a malformed link reference. This change modifies the generator to replace any spaces with hyphens before outputting link references, causing the resulting internal links to work correctly. This change also does some light refactoring to remove an unnecessary `switch` statement. * [auto] Update AMI IDs for 16.4.0 (#46746) Co-authored-by: GitHub <noreply@github.com> * Remove deprecated HTTP RemoteCluster endpoints (#46756) * Remove deprecated HTTP RemoteCluster endpoints * Remove redundant test * Add `tbot` helm chart to `version.mk` (#46763) * Remove LockConfiguration.LockName (#46772) Cleans up the deprecated config option now that gravitational/teleport.e#5034 has been merged. * adding a reference to to the host user guide (#46765) * Replace more Logrus usage with Slog (#46757) * Remove logrus from lib/auth/machineid * Switch authclient.Config.Log and TunnelAuthDialerConfig.Log to Slog * Add *slog.Logger to auth.Server * Remove logrus usage in `lib/auth/access.go` * Replace logrus with slog in lib/auth/accountrecovery.go * Replace logrus with slog in `lib/auth/apiserver.go` * Add missing logger to auth.Server * Fix test * Update AWS roles ARNs displayed on `tsh app login` for AWS console apps (#44983) * feat(tsh): list aws console logins from server * chore(services): remove unified resources change This is being covered on another PR. * test(tsh): solve TestAzure flakiness by waiting using app servers are ready * fix(tsh): apps with logins were fallingback into using aws arns * refactor(client): use GetEnrichedResources * chore(client): rename function * refactor(tsh): directly resource lisiting for apps and reuse cluster client * chore(client): reset client changes * refactor(tsh): reuse cluster client for fetching allowed logins * chore(tsh): remove unused function param * refactor(tsh): update getApp retry with login * refactor(tsh): use a single function to grab profile and cluste client * refactor(tsh): perform retry with login at caller site * fix(tsh): close auth client * test(tsh): fix test failing due to login misconfiguration * test(tsh): fix lint errors * test(tsh): remove unused imports * bulk audit event export api (#46399) * Reverting back to using the emitSessionJoin boolean * Nits and removing a debug log --------- Co-authored-by: Marco Dinis <marco.dinis@goteleport.com> Co-authored-by: Michael <michael.myers@goteleport.com> Co-authored-by: Paul Gottschling <paul.gottschling@goteleport.com> Co-authored-by: Rafał Cieślak <rafal.cieslak@goteleport.com> Co-authored-by: Nic Klaassen <nic@goteleport.com> Co-authored-by: Dan Johns <117299936+djohns7@users.noreply.github.com> Co-authored-by: Zac Bergquist <zac.bergquist@goteleport.com> Co-authored-by: Ryan Clark <ryan.clark@goteleport.com> Co-authored-by: Edoardo Spadolini <edoardo.spadolini@goteleport.com> Co-authored-by: Bernard Kim <bernard@goteleport.com> Co-authored-by: hugoShaka <hugo.hervieux@goteleport.com> Co-authored-by: Vadym Popov <vadym.popov@goteleport.com> Co-authored-by: Erik Tate <erik.tate@goteleport.com> Co-authored-by: teleport-post-release-automation[bot] <128860004+teleport-post-release-automation[bot]@users.noreply.github.com> Co-authored-by: GitHub <noreply@github.com> Co-authored-by: Noah Stride <noah.stride@goteleport.com> Co-authored-by: rosstimothy <39066650+rosstimothy@users.noreply.github.com> Co-authored-by: Gabriel Corado <gabriel.oliveira@goteleport.com> Co-authored-by: Forrest <30576607+fspmarshall@users.noreply.github.com>
