IPoIB: Fix crash in path_rec_completion()
Fix a crash in path_rec_completion() during an SM up/down loop. If more than one path record request is issued, the first completion releases path->done, allowing ipoib_flush_paths() to free the path, and thus corrupting it for the second completion. Commit ee1e2c82 ("IPoIB: Refresh paths instead of flushing them on SM change events") added the field path->valid and changed the test "if (!path)" to "if (!path || !path->valid)". This change made it possible for a path with an outstanding query to pass the test and issue another query on the same path. Having two queries on the same path leads to a crash. This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1325>. Signed-off-by: Yossi Etigin <yosefe@voltaire.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
