Subject: [PATCH opensm] osm_state_mgr.c: Improve error flow with wrong LIDs
Date: Thu, 26 Jun 2014 07:47:46 -0400 [thread overview]
Message-ID: <53AC0862.604@dev.mellanox.co.il> (raw)
From: Vladimir Koushnir <vladimirk-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>
In case of errors, setting NULL in the entry of port_lid_tbl
should be done only for LIDs assigned by lid manager in
order to avoid unnecessary expansion of port_lid_tbl and
further incorrect max_lid calculation that is based
on port_lid_tbl vector size.
