Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains a larger than usual batch of Netfilter fixes for your net tree. This series contains a mixture of old bugs and recently introduced bugs, they are: 1) Fix a crash when using nft_dynset with nft_set_rbtree, which doesn't support the set element updates from the packet path. From Liping Zhang. 2) Fix leak when nft_expr_clone() fails, from Liping Zhang. 3) Fix a race when inserting new elements to the set hash from the packet path, also from Liping. 4) Handle segmented TCP SIP packets properly, basically avoid that the INVITE in the allow header create bogus expectations by performing stricter SIP message parsing, from Ulrich Weber. 5) nft_parse_u32_check() should return signed integer for errors, from John Linville. 6) Fix wrong allocation instead of connlabels, allocate 16 instead of 32 bytes, from Florian Westphal. 7) Fix compilation breakage when building the ip_vs_sync code with CONFIG_OPTIMIZE_INLINING on x86, from Arnd Bergmann. 8) Destroy the new set if the transaction object cannot be allocated, also from Liping Zhang. 9) Use device to route duplicated packets via nft_dup only when set by the user, otherwise packets may not follow the right route, again from Liping. 10) Fix wrong maximum genetlink attribute definition in IPVS, from WANG Cong. 11) Ignore untracked conntrack objects from xt_connmark, from Florian Westphal. 12) Allow to use conntrack helpers that are registered NFPROTO_UNSPEC via CT target, otherwise we cannot use the h.245 helper, from Florian. 13) Revisit garbage collection heuristic in the new workqueue-based timer approach for conntrack to evict objects earlier, again from Florian. 14) Fix crash in nf_tables when inserting an element into a verdict map, from Liping Zhang. ==================== Signed-off-by: David S.
