From 0304ff8a2d5f57defb011c7f261b4c1b3eff96d1 Mon Sep 17 00:00:00 2001 From: Paolo Galtieri Date: Tue, 17 Apr 2007 12:52:36 -0700 Subject: [PATCH] [SCTP]: Unmap v4mapped addresses during SCTP_BINDX_REM_ADDR operation. During the sctp_bindx() call to add additional addresses to the endpoint, any v4mapped addresses are converted and stored as regular v4 addresses. However, when trying to remove these addresses, the v4mapped addresses are not converted and the operation fails. This patch unmaps the addresses on during the remove operation as well.
