2013-12-27ipvs: correct usage/allocation of seqadj ext in ipvsJesper Dangaard Brouer1-0/+6
The IPVS FTP helper ip_vs_ftp could trigger an OOPS in nf_ct_seqadj_set, after commit 41d73ec053d2 (netfilter: nf_conntrack: make sequence number adjustments usuable without NAT). This is because, the seqadj ext is now allocated dynamically, and the IPVS code didn't handle this situation. Fix this in the IPVS nfct code by invoking the alloc function nfct_seqadj_ext_add().

2013-12-27netfilter: WARN about wrong usage of sequence number adjustmentsJesper Dangaard Brouer1-0/+5
Since commit 41d73ec053d2 (netfilter: nf_conntrack: make sequence number adjustments usuable without NAT), the sequence number extension is dynamically allocated. Instead of dying, give a WARN splash, in case of wrong usage of the seqadj code, e.g. when forgetting to allocate via nfct_seqadj_ext_add(). Wrong usage have been seen in the IPVS code path.

2013-12-27ipvs: Remove unused variable ret from sync_thread_master()Geert Uytterhoeven1-1/+4
net/netfilter/ipvs/ip_vs_sync.c: In function 'sync_thread_master': net/netfilter/ipvs/ip_vs_sync.c:1640:8: warning: unused variable 'ret' [-Wunused-variable] Commit 35a2af94c7ce7130ca292c68b1d27fcfdb648f6b ("sched/wait: Make the __wait_event*() interface more friendly") changed how the interruption state is returned. However, sync_thread_master() ignores this state, now causing a compile warning. According to Julian Anastasov <ja@ssi.bg>, this behavior is OK: "Yes, your patch looks ok to me. In the past we used ssleep() but IPVS users were confused why IPVS threads increase the load average. So, we switched to _interruptible calls and later the socket polling was added." Document this, as requested by Peter Zijlstra, to avoid precious developers disappearing in this pitfall in the future.

2013-12-26sch_tbf: add TBF_BURST/TBF_PBURST attributeYang Yingliang1-5/+24
When we set burst to 1514 with low rate in userspace, the kernel get a value of burst that less than 1514, which doesn't work. Because it may make some loss when transform burst to buffer in userspace. This makes burst lose some bytes, when the kernel transform the buffer back to burst. This patch adds two new attributes to support sending burst/mtu to kernel directly to avoid the loss.

We report different pmtu values back on the first write and on further writes on an corked socket. Also don't include the dst.header_len (respectively exthdrlen) as this should already be dealt with by the interface mtu of the outgoing (virtual) interface and policy of that interface should dictate if fragmentation should happen. Instead reduce the pmtu data by IP options as we do for IPv6. Make the same changes for ip_append_data, where we did not care about options or dst.header_len at all.

In commit 93b36cf3425b9b ("ipv6: support IPV6_PMTU_INTERFACE on sockets") I made a horrible mistake to add ip6_sk_accept_pmtu to the generic sctp_icmp_frag_needed path. This results in build warnings if IPv6 is disabled which were luckily caught by Fengguang's kbuild bot. But it also leads to a kernel panic IPv4 frag-needed packet is received.

2013-12-21tcp: autocork should not hold first packet in write queueEric Dumazet1-4/+10
Willem noticed a TCP_RR regression caused by TCP autocorking on a Mellanox test bed. MLX4_EN_TX_COAL_TIME is 16 us, which can be right above RTT between hosts. We can receive a ACK for a packet still in NIC TX ring buffer or in a softnet completion queue. Fix this by always pushing the skb if it is at the head of write queue. Also, as TX completion is lockless, it's safer to perform sk_wmem_alloc test after setting TSQ_THROTTLED. erd:~# MIB="MIN_LATENCY,MEAN_LATENCY,MAX_LATENCY,P99_LATENCY,STDDEV_LATENCY" erd:~# ./netperf -H remote -t TCP_RR -- -o $MIB | tail -n 1 (repeat 3 times) Before patch : 18,1049.87,41004,39631,6295.47 17,239.52,40804,48,2912.79 18,348.40,40877,54,3573.39 After patch : 18,22.84,4606,38,16.39 17,21.56,2871,36,13.51 17,22.46,2705,37,11.83 Reported-by: Willem de Bruijn <willemb@google.com> Signed-off-by: Eric Dumazet <edumazet@google.com> Fixes: f54b311142a9 ("tcp: auto corking") Signed-off-by: David S.

2013-12-20netfilter: nft_exthdr: call ipv6_find_hdr() with explicitly initialized offsetDaniel Borkmann1-1/+1
In nft's nft_exthdr_eval() routine we process IPv6 extension header through invoking ipv6_find_hdr(), but we call it with an uninitialized offset variable that contains some stack value. In ipv6_find_hdr() we then test if the value of offset != 0 and call skb_header_pointer() on that offset in order to map struct ipv6hdr into it. Fix it up by initializing offset to 0 as it was probably intended to be.

2013-12-20netfilter: ctnetlink: honor CTA_MARK_MASK when setting ctmarkFlorian Westphal1-2/+10
Useful to only set a particular range of the conntrack mark while leaving exisiting parts of the value alone, e.g. when setting conntrack marks via NFQUEUE. Follows same scheme as MARK/CONNMARK targets, i.e. the mask defines those bits that should be altered. No mask is equal to '~0', ie. the old value is replaced by new one.

2013-12-20netfilter: avoid get_random_bytes callsFlorian Westphal6-13/+5
All these users need an initial seed value for jhash, prandom is perfectly fine. This avoids draining the entropy pool where its not strictly required. nfnetlink_log did not use the random value at all.
