UidGidResolver

The UidGidResolver resolves user ids and group ids to their corresponding names.

This is done by reading /etc/passwd and /etc/group on the host. Therefore any UID inside a container might not properly match the username inside the container. Since the path is hardcoded usernames provided through ldap, nss-systemd, systemd units with DynamicUser=yes, ... will not be resolved correctly.

Usage

Classic gadgets

1. Implement the UidResolverInterface for the event struct to resolve a UID. The UID which is returned by GetUid() will be resolved to the corresponding username and is passed into SetUserName(...)

   type UidResolverInterface interface {
     GetUid() uint32
     SetUserName(string)
   }
2. Implement the GidResolverInterface for the event struct to a resolve GID. The GID which is returned by GetGid() will be resolved to the corresponding groupname and is passed into SetGroupName(...)

   type GidResolverInterface interface {
     GetGid() uint32
     SetGroupName(string)
   }
