From 63c47c286d062d93e0501d60797274c84a587e97 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Mon, 26 Sep 2005 13:01:03 -0700 Subject: [IB] uverbs: Close some exploitable races Al Viro pointed out that the current IB userspace verbs interface allows userspace to cause mischief by closing file descriptors before we're ready, or issuing the same command twice at the same time. This patch closes those races, and fixes other obvious problems such as a module reference leak. Some other interface bogosities will require an ABI change to fix properly, so I'm deferring those fixes until 2.6.15.
