.golangci.yml

linters-settings:
  custom:
    example:
      path: ./example.so

linters:
  enable-all: true

Custom linters work for enable-all.

Hello,

for security reasons, I think it's a bad idea to do that.

[yuqengo]

Hello, Thanks for review!

What security reasons do you have?

[ldez]

I thought about the subject and I think there is a bug because the activation of plugins should be done by default. https://github.com/golangci/golangci-lint/blob/011252127f53cf6a0f2b28dc97fed55508575b09/pkg/lint/lintersdb/manager.go#L983

The current implementation inside golangci-lint has some design problems.

I think I will fix design problems and the behavior of the plugin in another PR.
