You can notice that this batch contains a couple of fixes that may go to 3.6-rc but I don't consider them critical to push them: * The ipset fix for the /0 cidr case, which is triggered with one inconsistent command line invocation of ipset. * The nfnetlink_queue maximum packet length supported since it requires the new NFQA_CAP_LEN attribute to provide a full workaround for the described problem. ==================== Signed-off-by: David S.

2012-09-24netfilter: nfnetlink_queue: add NFQA_CAP_LEN attributePablo Neira Ayuso
This patch adds the NFQA_CAP_LEN attribute that allows us to know what is the real packet size from user-space (even if we decided to retrieve just a few bytes from the packet instead of all of it). Security software that inspects packets should always check for this new attribute to make sure that it is inspecting the entire packet. This also helps to provide a workaround for the problem described in: http://marc.info/?l=netfilter-devel&m=134519473212536&w=2 Original idea from Florian Westphal.

2012-09-24netfilter: nfnetlink_queue: fix maximum packet length to userspacePablo Neira Ayuso
The packets that we send via NFQUEUE are encapsulated in the NFQA_PAYLOAD attribute. The length of the packet in userspace is obtained via attr->nla_len field. This field contains the size of the Netlink attribute header plus the packet length. If the maximum packet length is specified, ie. 65535 bytes, and packets in the range of (65531,65535] are sent to userspace, the attr->nla_len overflows and it reports bogus lengths to the application. To fix this, this patch limits the maximum packet length to 65531 bytes. If larger packet length is specified, the packet that we send to user-space is truncated to 65531 bytes. To support 65535 bytes packets, we have to revisit the idea of the 32-bits Netlink attribute length.

2012-09-24netfilter: nf_ct_ftp: add sequence tracking pickup facility for injected entriesPablo Neira Ayuso
This patch allows the FTP helper to pickup the sequence tracking from the first packet seen. This is useful to fix the breakage of the first FTP command after the failover while using conntrackd to synchronize states. The seq_aft_nl_num field in struct nf_ct_ftp_info has been shrinked to 16-bits (enough for what it does), so we can use the remaining 16-bits to store the flags while using the same size for the private FTP helper data.

2012-09-24netfilter: xt_time: add support to ignore day transitionFlorian Westphal
Currently, if you want to do something like: "match Monday, starting 23:00, for two hours" You need two rules, one for Mon 23:00 to 0:00 and one for Tue 0:00-1:00. The rule: --weekdays Mo --timestart 23:00 --timestop 01:00 looks correct, but it will first match on monday from midnight to 1 a.m. and then again for another hour from 23:00 onwards. This permits userspace to explicitly ignore the day transition and match for a single, continuous time period instead.

2012-09-22tcp: TCP Fast Open Server - record retransmits after 3WHSNeal Cardwell
When recording the number of SYNACK retransmits for servers using TCP Fast Open, fix the code to ensure that we copy over the retransmit count from the request_sock after we receive the ACK that completes the 3-way handshake. The story here is similar to that of SYNACK RTT measurements. Previously we were always doing this in tcp_v4_syn_recv_sock(). However, for TCP Fast Open connections tcp_v4_conn_req_fastopen() calls tcp_v4_syn_recv_sock() at the time we receive the SYN. So for TFO we must copy the final SYNACK retransmit count in tcp_rcv_state_process(). Note that copying over the SYNACK retransmit count will give us the correct count since, as is mentioned in a comment in tcp_retransmit_timer(), before we receive an ACK for our SYN-ACK a TFO passive connection does not retransmit anything else (e.g., data or FIN segments).

2012-09-22tcp: TCP Fast Open Server - call tcp_validate_incoming() for all packetsNeal Cardwell
A TCP Fast Open (TFO) passive connection must call both tcp_check_req() and tcp_validate_incoming() for all incoming ACKs that are attempting to complete the 3WHS. This is needed to parallel all the action that happens for a non-TFO connection, where for an ACK that is attempting to complete the 3WHS we call both tcp_check_req() and tcp_validate_incoming(). For example, upon receiving the ACK that completes the 3WHS, we need to call tcp_fast_parse_options() and update ts_recent based on the incoming timestamp value in the ACK. One symptom of the problem with the previous code was that for passive TFO connections using TCP timestamps, the outgoing TS ecr values ignored the incoming TS val value on the ACK that completed the 3WHS.

2012-09-22tcp: TCP Fast Open Server - note timestamps and retransmits for SYNACK RTTNeal Cardwell
Previously, when using TCP Fast Open a server would return from tcp_check_req() before updating snt_synack based on TCP timestamp echo replies and whether or not we've retransmitted the SYNACK. The result was that (a) for TFO connections using timestamps we used an incorrect baseline SYNACK send time (tcp_time_stamp of SYNACK send instead of rcv_tsecr), and (b) for TFO connections that do not have TCP timestamps but retransmit the SYNACK we took a SYNACK RTT sample when we should not take a sample. This fix merely moves the snt_synack update logic a bit earlier in the function, so that connections using TCP Fast Open will properly do these updates when the ACK for the SYNACK arrives. Moving this snt_synack update logic means that with TCP_DEFER_ACCEPT enabled we do a few instructions of wasted work on each bare ACK, but that seems OK.

2012-09-22tcp: TCP Fast Open Server - take SYNACK RTT after completing 3WHSNeal Cardwell
When taking SYNACK RTT samples for servers using TCP Fast Open, fix the code to ensure that we only call tcp_valid_rtt_meas() after we receive the ACK that completes the 3-way handshake. Previously we were always taking an RTT sample in tcp_v4_syn_recv_sock(). However, for TCP Fast Open connections tcp_v4_conn_req_fastopen() calls tcp_v4_syn_recv_sock() at the time we receive the SYN. So for TFO we must wait until tcp_rcv_state_process() to take the RTT sample. To fix this, we wait until after TFO calls tcp_v4_syn_recv_sock() before we set the snt_synack timestamp, since tcp_synack_rtt_meas() already ensures that we only take a SYNACK RTT sample if snt_synack is non-zero. To be careful, we only take a snt_synack timestamp when a SYNACK transmit or retransmit succeeds. Signed-off-by: Neal Cardwell <ncardwell@google.com> Signed-off-by: David S.

2012-09-22igb: Use dma_unmap_addr and dma_unmap_len definesAlexander Duyck
This change is meant to improve performance on systems that do not require the DMA unmap calls. On those systems we do not need to make use of the unmap address for Tx or the unmap length so we can drop both thereby reducing the size of the Tx buffer info structure. In addition I have changed the logic to check for unmap length instead of unmap address when checking to see if a buffer needs to be unmapped from DMA use. The reasons for this change is that on some platforms it is possible to receive a valid DMA address of 0 from an IOMMU.
