Merge branch 'master' into ide-file-finder

.gitlab/issue_templates/Security Developer Workflow.md

+<!--
+# Read me first!
+
+Create this issue under https://dev.gitlab.org/gitlab/gitlabhq
+
+Set the title to: `[Security] Description of the original issue`
+-->
+
+### Prior to the security release
+
+- [ ] Read the [security process for developers] if you are not familiar with it.
+- [ ] Link to the original issue adding it to the [links section](#links)
+- [ ] Run `scripts/security-harness` in the CE, EE, and/or Omnibus to prevent pushing to any remote besides `dev.gitlab.org`
+- [ ] Create an MR targetting `org` `master`, prefixing your branch with `security-`
+- [ ] Label your MR with the ~security label, prefix the title with `WIP: [master]`   
+- [ ] Add a link to the MR to the [links section](#links)
+- [ ] Add a link to an EE MR if required
+- [ ] Make sure the MR remains in-progress and gets approved after the review cycle, **but never merged**.
+- [ ] Assign the MR to a RM once is reviewed and ready to be merged. Check the [RM list] to see who to ping.
+
+#### Backports
+
+- [ ] Once the MR is ready to be merged, create MRs targetting the last 3 releases
+    - [ ] At this point, it might be easy to squash the commits from the MR into one
+    - You can use the script `bin/secpick` instead of the following steps, to help you cherry-picking. See the [seckpick documentation]
+    - [ ] Create the branch `security-X-Y` from `X-Y-stable` if it doesn't exist (and make sure it's up to date with stable)
+    - [ ] Create each MR targetting the security branch `security-X-Y`
+    - [ ] Add the ~security label and prefix with the version `WIP: [X.Y]` the title of the MR
+- [ ] Make sure all MRs have a link in the [links section](#links) and are assigned to a Release Manager.
+

+
+#### Documentation and final details
+
+- [ ] Check the topic on #security to see when the next release is going ot happen and add a link to the [links section](#links)
+- [ ] Find out the versions affected (the Git history of the files affected may help you with this) and add them to the [details section](#details)
+- [ ] Fill in any upgrade notes that users may need to take into account in the [details section](#details)
+- [ ] Add Yes/No and further details if needed to the migration and settings columns in the [details section](#details)
+- [ ] Add the nickname of the external user who found the issue (and/or HackerOne profile) to the Thanks row in the [details section](#details)
