"plugin exited before we could connect" while mount

* plugin exited before we could connect

Vault 0.9.1

I've tried:

• https://github.com/sethvargo/vault-secrets-gen/releases/download/v0.0.1/vault-secrets-gen_0.0.1_linux_amd64.tgz
• https://github.com/sethvargo/vault-secrets-gen/releases/download/v0.0.1/vault-secrets-gen_0.0.1_linux_amd64.zip

on Linux 70f3206690e2 4.6.0-0.bpo.1-amd64 #1 SMP Debian 4.6.1-1~bpo8+1 (2016-06-14) x86_64 Linux.

In logs I see only:

2018/03/07 11:25:23.956931 [ERROR] sys: mount failed: path=gen/ error=plugin exited before we could connect

top-level api_address is set (as suggested in #2).

Hey @mlowicki

I'm unable to reproduce this on my end, but I don't have access to that version of Debian. Can you please try using Vault 0.9.4 (or later) and the latest version of the plugin (v0.0.2)?

I think, we had the same problem. If Vault is using mlock, then the plugin needs the capability, too:
setcap cap_ipc_lock=+ep <path_to_plugin>/vault-secrets-gen solved it for us.

Closing due to lack of response.
