* netfilter: connlimit: improve packet-to-closed-connection logicFlorian Westphal2014-03-12
| | | | | | | | | | | Instead of freeing the entry from our list and then adding it back again in the 'packet to closing connection' case just keep the matching entry around. Also drop the found_ct != NULL test as nf_ct_tuplehash_to_ctrack is just container_of().

* netfilter: nft_nat: fix family validationPatrick McHardy2014-03-08
| | | | | | | | | | | | | | | | | The family in the NAT expression is basically completely useless since we have it available during runtime anyway. Nevertheless it is used to decide the NAT family, so at least validate it properly. As we don't support cross-family NAT, it needs to match the family of the table the expression exists in. Unfortunately we can't remove it completely since we need to dump it for userspace (*sigh*), so at least reduce the memory waste. Additionally clean up the module init function by removing useless temporary variables. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* netfilter: nft_hash: bug fixes and resizingPatrick McHardy2014-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hash set type is very broken and was never meant to be merged in this state. Missing RCU synchronization on element removal, leaking chain refcounts when used as a verdict map, races during lookups, a fixed table size are probably just some of the problems. Luckily it is currently never chosen by the kernel when the rbtree type is also available. Rewrite it to be usable. The new implementation supports automatic hash table resizing using RCU, based on Paul McKenney's and Josh Triplett's algorithm "Optimized Resizing For RCU-Protected Hash Tables" described in [1]. Resizing doesn't require a second list head in the elements, it works by chosing a hash function that remaps elements to a predictable set of buckets, only resizing by integral factors and - during expansion: linking new buckets to the old bucket that contains elements for any of the new buckets, thereby creating imprecise chains, then incrementally seperating the elements until the new buckets only contain elements that hash directly to them. - during shrinking: linking the hash chains of all old buckets that hash to the same new bucket to form a single chain. Expansion requires at most the number of elements in the longest hash chain grace periods, shrinking requires a single grace period. Due to the requirement of having hash chains/elements linked to multiple buckets during resizing, homemade single linked lists are used instead of the existing list helpers, that don't support this in a clean fashion. As a side effect, the amount of memory required per element is reduced by one pointer. Expansion is triggered when the load factors exceeds 75%, shrinking when the load factor goes below 30%. Both operations are allowed to fail and will be retried on the next insertion or removal if their respective conditions still hold.

* netfilter: conntrack: remove central spinlock nf_conntrack_lockJesper Dangaard Brouer2014-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nf_conntrack_lock is a monolithic lock and suffers from huge contention on current generation servers (8 or more core/threads). Perf locking congestion is clear on base kernel: - 72.56% ksoftirqd/6 [kernel.kallsyms] [k] _raw_spin_lock_bh - _raw_spin_lock_bh + 25.33% init_conntrack + 24.86% nf_ct_delete_from_lists + 24.62% __nf_conntrack_confirm + 24.38% destroy_conntrack + 0.70% tcp_packet + 2.21% ksoftirqd/6 [kernel.kallsyms] [k] fib_table_lookup + 1.15% ksoftirqd/6 [kernel.kallsyms] [k] __slab_free + 0.77% ksoftirqd/6 [kernel.kallsyms] [k] inet_getpeer + 0.70% ksoftirqd/6 [nf_conntrack] [k] nf_ct_delete + 0.55% ksoftirqd/6 [ip_tables] [k] ipt_do_table This patch change conntrack locking and provides a huge performance improvement. SYN-flood attack tested on a 24-core E5-2695v2(ES) with 10Gbit/s ixgbe (with tool trafgen): Base kernel: 810.405 new conntrack/sec After patch: 2.233.876 new conntrack/sec Notice other floods attack (SYN+ACK or ACK) can easily be deflected using: # iptables -A INPUT -m state --state INVALID -j DROP # sysctl -w net/netfilter/nf_conntrack_tcp_loose=0 Use an array of hashed spinlocks to protect insertions/deletions of conntracks into the hash table. 1024 spinlocks seem to give good results, at minimal cost (4KB memory). Due to lockdep max depth, 1024 becomes 8 if CONFIG_LOCKDEP=y The hash resize is a bit tricky, because we need to take all locks in the array. A seqcount_t is used to synchronize the hash table users with the resizing process.

* netfilter: avoid race with exp->master ctJesper Dangaard Brouer2014-03-07
| | | | | | | | | | | | | | | | | | | | Preparation for disconnecting the nf_conntrack_lock from the expectations code. Once the nf_conntrack_lock is lifted, a race condition is exposed. The expectations master conntrack exp->master, can race with delete operations, as the refcnt increment happens too late in init_conntrack(). Race is against other CPUs invoking ->destroy() (destroy_conntrack()), or nf_ct_delete() (via timeout or early_drop()). Avoid this race in nf_ct_find_expectation() by using atomic_inc_not_zero(), and checking if nf_ct_is_dying() (path via nf_ct_delete()).

* | netfilter: ipset: add forceadd kernel support for hash set typesJosh Hunt2014-03-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds a new property for hash set types, where if a set is created with the 'forceadd' option and the set becomes full the next addition to the set may succeed and evict a random entry from the set. To keep overhead low eviction is done very simply. It checks to see which bucket the new entry would be added. If the bucket's pos value is non-zero (meaning there's at least one entry in the bucket) it replaces the first entry in the bucket. If pos is zero, then it continues down the normal add process. This property is useful if you have a set for 'ban' lists where it may not matter if you release some entries from the set early.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 2dfb973c0dcc6d2211 (add markmask for hash:ip,mark data type) inserted IPSET_ATTR_MARKMASK in-between other enum values, i.e. changing values of all further attributes. This causes 'ipset list' segfault on existing kernels since ipset no longer finds IPSET_ATTR_MEMSIZE (it has a different value on kernel side).

* | netfilter: ipset: Follow manual page behavior for SET target on list:setSergey Popovich2014-03-06
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ipset(8) for list:set says: The match will try to find a matching entry in the sets and the target will try to add an entry to the first set to which it can be added. However real behavior is bit differ from described. Consider example: # ipset create test-1-v4 hash:ip family inet # ipset create test-1-v6 hash:ip family inet6 # ipset create test-1 list:set # ipset add test-1 test-1-v4 # ipset add test-1 test-1-v6 # iptables -A INPUT -p tcp --destination-port 25 -j SET --add-set test-1 src # ip6tables -A INPUT -p tcp --destination-port 25 -j SET --add-set test-1 src And then when iptables/ip6tables rule matches packet IPSET target tries to add src from packet to the list:set test-1 where first entry is test-1-v4 and the second one is test-1-v6. For IPv4, as it first entry in test-1 src added to test-1-v4 correctly, but for IPv6 src not added! Placing test-1-v6 to the first element of list:set makes behavior correct for IPv6, but brokes for IPv4. This is due to result, returned from ip_set_add() and ip_set_del() from net/netfilter/ipset/ip_set_core.c when set in list:set equires more parameters than given or address families do not match (which is this case). It seems wrong returning 0 from ip_set_add() and ip_set_del() in this case, as 0 should be returned only when an element successfuly added/deleted to/from the set, contrary to ip_set_test() which returns 0 when no entry exists and >0 when entry found in set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CP semaphore queue on CIK has a bug that triggers if uncompleted waits use the same address while a signal is still pending. Work around this by using different addresses for each sync.
