Using 2.6.11-rc3 with Openswan, no IPSEC SA can be established. Kernel logs "kernel: ESP: md5 digestsize 16 != 0" and netlink returns an error.
The changes to XFRM in 2.6.11-rc3 have an error in xfrm_algo.c such that xfrm_aalg_get_byname() always returns digest_null (which would indeed have a zero length digest...) The problem is here: $ diff -Naur net/xfrm/xfrm_algo.c* --- net/xfrm/xfrm_algo.c 2005-02-04 18:05:53.000000000 -0500 +++ net/xfrm/xfrm_algo.c~ 2005-02-04 08:08:16.000000000 -0500 @@ -357,7 +357,7 @@ return NULL; for (i = 0; i < entries; i++) { - if (strcmp(name, list[i].name) != 0) + if (!strcmp(name, list[i].name)) continue; if (list[i].available) where the sense of (!strcmp()) is reversed. It's easier to read by explicitly comparing to zero, IMHO, as I did in this patch. -- Andy <[EMAIL PROTECTED]> - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
