From f8f3d4de2d04e1a5b4293b67faee8ebabc64e9fa Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Tue, 7 Feb 2012 16:54:50 -0800 Subject: userns: Convert bsd process accounting to use kuid and kgid where appropriate BSD process accounting conveniently passes the file the accounting records will be written into to do_acct_process. The file credentials captured the user namespace of the opener of the file. Use the file credentials to format the uid and the gid of the current process into the user namespace of the user that started the bsd process accounting.
