Hi, Krzysztof Oledzki discovered a serious bug in the 2.4.x versions of ipset: when flushing a nethash/ipportnethash type of set, it can lead to a kernel crash due to a wrong type declaration in the flush functions. Also, for a successful compilation with kernel versions above 2.6.26.6, an include file was missing from ip_set_iptree.c and ip_set_iptreemap.c. Please upgrade to ipset 2.4.2. You can download the source of ipset from the webpage or svn: http://ipset.netfilter.org/ svn co https://svn.netfilter.org/netfilter/trunk/ipset Best regards, Jozsef - E-mail : kadlec@xxxxxxxxxxxxxxxxx, kadlec@xxxxxxxxxxxx PGP key : http://www.kfki.hu/~kadlec/pgp_public_key.txt Address : KFKI Research Institute for Particle and Nuclear Physics H-1525 Budapest 114, POB. 49, Hungary -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
