Subject: [patch 17/26] Fix module refcount leak in __set_personality()
Date: Tue, 4 Apr 2006 17:00:53 -0700 [thread overview]
Message-ID: <20060405000053.GR27049@kroah.com> (raw)
In-Reply-To: <20060404235927.GA27049@kroah.com>
[-- Attachment #1: fix-module-refcount-leak-in.patch --]
[-- Type: text/plain, Size: 873 bytes --]
From: Sergey Vlasov <vsu@altlinux.ru>
If the change of personality does not lead to change of exec domain,
__set_personality() returned without releasing the module reference
acquired by lookup_exec_domain().
This patch was already included in Linus' tree.
