Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for your net-next tree, they are: 1) Consolidate GRE protocol tracker using new GRE protocol definitions, patches from Gao Feng. 2) Properly parse continuation lines in SIP helper, update allowed characters in Call-ID header and allow tabs in SIP headers as specified by RFC3261, from Marco Angaroni. 3) Remove useless code in FTP conntrack helper, also from Gao Feng. 4) Add number generation expression for nf_tables, with random and incremental generators. This also includes specific offset to add to the result, patches from Laura Garcia Liebana. Liping Zhang follows with a fix to avoid a race in this new expression. 5) Fix new quota expression inversion logic, added in the previous pull request. 6) Missing validation of queue configuration in nft_queue, patch from Liping Zhang. 7) Remove unused ctl_table_path, as part of the deprecation of the ip_conntrack sysctl interface coming in the previous batch. Again from Liping Zhang. 8) Add offset attribute to nft_hash expression, so we can generate any output from a specific base offset. Moreover, check for possible overflow, patches from Laura Garcia. 9) Allow to invert dynamic set insertion from packet path, to check for overflows in case the set is full. 10) Revisit nft_set_pktinfo*() logic from nf_tables to ensure proper initialization of layer 4 protocol. Consolidate pktinfo structure initialization for bridge and netdev families. 11) Do not inconditionally drop IPv6 packets that we cannot parse transport protocol for ip6 and inet families, let the user decide on this via ruleset policy. 12) Get rid of gotos in __nf_ct_try_assign_helper(). 13) Check for return value in register_netdevice_notifier() and nft_register_chain_type(), patches from Gao Feng. 14) Get rid of CONFIG_IP6_NF_IPTABLES dependency in nf_queue infrastructure that is common to nf_tables, from Liping Zhang. 15) Disable 'found' and 'searched' stats that are updates from the packet hotpath, not very useful these days. 16) Validate maximum value of u32 netlink attributes in nf_tables, this introduces nft_parse_u32_check(). From Laura Garcia. 17) Add missing code to integrate nft_queue with maps, patch from Liping Zhang. This also includes missing support ranges in nft_queue bridge family. 18) Fix check in nft_payload_fast_eval() that ensure that we don't go over the skbuff data boundary, from Liping Zhang. 19) Check if transport protocol is set from nf_tables tracing and payload expression. Again from Liping Zhang. 20) Use net_get_random_once() whenever possible, from Gao Feng. 21) Replace hardcoded value by sizeof() in xt_helper, from Gao Feng. 22) Remove superfluous check for found element in nft_lookup. 23) Simplify TCPMSS logic to check for minimum MTU, from Gao Feng. 24) Replace double linked list by single linked list in Netfilter core hook infrastructure, patchset from Aaron Conole. This includes several patches to prepare this update. 25) Fix wrong sequence adjustment of TCP RST with no ACK, from Gao Feng. 26) Relax check for direction attribute in nft_ct for layer 3 and 4 protocol fields, from Liping Zhang. 27) Add new revision for hashlimit to support higher pps of upto 1 million, from Vishwanath Pai. 28) Evict stale entries in nf_conntrack when reading entries from /proc/net/nf_conntrack, from Florian Westphal. 29) Fix transparent match for IPv6 request sockets, from Krisztian Kovacs. 30) Add new range expression for nf_tables. 31) Add missing code to support for flags in nft_log. Expose NF_LOG_* flags via uapi and use it from the generic logging infrastructure, instead of using xt specific definitions, from Liping Zhang. ==================== Signed-off-by:

NFTA_LOG_FLAGS attribute is already supported, but the related NF_LOG_XXX flags are not exposed to the userspace. So we cannot explicitly enable log flags to log uid, tcp sequence, ip options and so on, i.e. such rule "nft add rule filter output log uid" is not supported yet. So move NF_LOG_XXX macro definitions to the uapi/../nf_log.h. In order to keep consistent with other modules, change NF_LOG_MASK to refer to all supported log flags. On the other hand, add a new NF_LOG_DEFAULT_MASK to refer to the original default log flags. Finally, if user specify the unsupported log flags or NFTA_LOG_GROUP and NFTA_LOG_FLAGS are set at the same time, report EINVAL to the userspace. Signed-off-by:

The introduction of TCP_NEW_SYN_RECV state, and the addition of request sockets to the ehash table seems to have broken the --transparent option of the socket match for IPv6 (around commit a9407000). Now that the socket lookup finds the TCP_NEW_SYN_RECV socket instead of the listener, the --transparent option tries to match on the no_srccheck flag of the request socket. Unfortunately, that flag was only set for IPv4 sockets in tcp_v4_init_req() by copying the transparent flag of the listener socket. This effectively causes '-m socket --transparent' not match on the ACK packet sent by the client in a TCP handshake. Based on the suggestion from Eric Dumazet, this change moves the code initializing no_srccheck to tcp_conn_request(), rendering the above scenario working again.

Fabian reports a possible conntrack memory leak (could not reproduce so far), however, one minor issue can be easily resolved: > cat /proc/net/nf_conntrack | wc -l = 5 > 4 minutes required to clean up the table. We should not report those timed-out entries to the user in first place. And instead of just skipping those timed-out entries while iterating over the table we can also zap them (we already do this during ctnetlink walks, but I forgot about the /proc interface).

Create a new revision for the hashlimit iptables extension module. Rev 2 will support higher pps of upto 1 million, Version 1 supports only 10k. To support this we have to increase the size of the variables avg and burst in hashlimit_cfg to 64-bit. Create two new structs hashlimit_cfg2 and xt_hashlimit_mtinfo2 and also create newer versions of all the functions for match, checkentry and destroy. Some of the functions like hashlimit_mt, hashlimit_mt_check etc are very similar in both rev1 and rev2 with only minor changes, so I have split those functions and moved all the common code to a *_common function.

Currently, if the user want to match ct l3proto, we must specify the direction, for example: # nft add rule filter input ct original l3proto ipv4 ^^^^^^^^ Otherwise, error message will be reported: # nft add rule filter input ct l3proto ipv4 nft add rule filter input ct l3proto ipv4 <cmdline>:1:1-38: Error: Could not process rule: Invalid argument add rule filter input ct l3proto ipv4 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Actually, there's no need to require NFTA_CT_DIRECTION attr, because ct l3proto and protocol are unrelated to direction. And for compatibility, even if the user specify the NFTA_CT_DIRECTION attr, do not report error, just skip it. Signed-off-by:

It is valid that the TCP RST packet which does not set ack flag, and bytes of ack number are zero. But current seqadj codes would adjust the "0" ack to invalid ack number. Actually seqadj need to check the ack flag before adjust it for these RST packets. The following is my test case client is 10.26.98.245, and add one iptable rule: iptables -I INPUT -p tcp --sport 12345 -m connbytes --connbytes 2: --connbytes-dir reply --connbytes-mode packets -j REJECT --reject-with tcp-reset This iptables rule could generate on TCP RST without ack flag. server:10.172.135.55 Enable the synproxy with seqadjust by the following iptables rules iptables -t raw -A PREROUTING -i eth0 -p tcp -d 10.172.135.55 --dport 12345 -m tcp --syn -j CT --notrack iptables -A INPUT -i eth0 -p tcp -d 10.172.135.55 --dport 12345 -m conntrack --ctstate INVALID,UNTRACKED -j SYNPROXY --sack-perm --timestamp --wscale 7 --mss 1460 iptables -A OUTPUT -o eth0 -p tcp -s 10.172.135.55 --sport 12345 -m conntrack --ctstate INVALID,UNTRACKED -m tcp --tcp-flags SYN,RST,ACK SYN,ACK -j ACCEPT The following is my test result. 1. packet trace on client root@routers:/tmp# tcpdump -i eth0 tcp port 12345 -n tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes IP 10.26.98.245.45154 > 10.172.135.55.12345: Flags [S], seq 3695959829, win 29200, options [mss 1460,sackOK,TS val 452367884 ecr 0,nop,wscale 7], length 0 IP 10.172.135.55.12345 > 10.26.98.245.45154: Flags [S.], seq 546723266, ack 3695959830, win 0, options [mss 1460,sackOK,TS val 15643479 ecr 452367884, nop,wscale 7], length 0 IP 10.26.98.245.45154 > 10.172.135.55.12345: Flags [.], ack 1, win 229, options [nop,nop,TS val 452367885 ecr 15643479], length 0 IP 10.172.135.55.12345 > 10.26.98.245.45154: Flags [.], ack 1, win 226, options [nop,nop,TS val 15643479 ecr 452367885], length 0 IP 10.26.98.245.45154 > 10.172.135.55.12345: Flags [R], seq 3695959830, win 0, length 0 2. seqadj log on server [62873.867319] Adjusting sequence number from 602341895->546723267, ack from 3695959830->3695959830 [62873.867644] Adjusting sequence number from 602341895->546723267, ack from 3695959830->3695959830 [62873.869040] Adjusting sequence number from 3695959830->3695959830, ack from 0->55618628 To summarize, it is clear that the seqadj codes adjust the 0 ack when receive one TCP RST packet without ack.

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2016-09-24 This series contains updates to i40e and i40evf only. Harshitha removes the ability to set or advertise X722 to 100 Mbps, since it is not supported, so we should not be able to advertise or set the NIC to 100 Mbps. Alan fixes an issue where deleting a MAC filter did not really delete the filter in question. The reason being that the wrong cmd_flag is passed to the firmware. Preethi adds the encapsulation checksum offload negotiation flag, so that we can control it. Jake cleans up the ATR auto_disable_flags use, since some locations disable ATR accidentally using the "full" disable by disabling the flag in the standard flags field. This permanently forces ATR off instead of temporarily disabling it. Then updated checks to include when there are TCP/IP4 sideband rules in effect, where ATR should be disabled. Lastly, adds support to the i40evf driver for setting interrupt moderation values per queue, like in i40e. Henry cleans up unreachable code, since i40e_shutdown_adminq() is always true. Mitch enables support for adaptive interrupt throttling, since all the code for it is already in the interrupt handler. The fixes a rare case where we might get a VSI with no queues and we try to configure RSS, which would result in a divide by zero. Alex fixes an issue where transmit cleanup flow was incorrectly assuming it could check for the flow director bits after it had unmapped the buffer. Then adds a txring_txq() to allow us to convert a i40e_ring/ i40evf_ring to a netdev_tx_queue structure, like ixgbe and fm10k. This avoids having to make a multi-line function call for all the areas that need access to it. Re-factors the Flow Director filter configuration out into a separate function, like we did for the standard xmit path. Cleans up the debugfs hook for Flow Director since it was meant for debug only. ==================== Signed-off-by:

Merge tag 'rxrpc-rewrite-20160924' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs David Howells says: ==================== rxrpc: Implement slow-start and other bits This set of patches implements the RxRPC slow-start feature for AF_RXRPC to improve performance and handling of occasional packet loss. This is more or less the same as TCP slow start [RFC 5681]. Firstly, there are some ACK generation improvements: (1) Send ACKs regularly to apprise the peer of our state so that they can do congestion management of their own. (2) Send an ACK when we fill in a hole in the buffer so that the peer can find out that we did this thus forestalling retransmission. (3) Note the final DATA packet's serial number in the final ACK for correlation purposes. and a couple of bug fixes: (4) Reinitialise the ACK state and clear the ACK and resend timers upon entering the client reply reception phase to kill off any pending probe ACKs. (5) Delay the resend timer to allow for nsec->jiffies conversion errors. and then there's the slow-start pieces: (6) Summarise an ACK. (7) Schedule a PING or IDLE ACK if the reply to a client call is overdue to try and find out what happened to it. (8) Implement the slow start feature. ==================== Signed-off-by:

In commit a75e8005 ("i40e: queue-specific settings for interrupt moderation") the i40e driver gained support for setting interrupt moderation values per queue. This patch adds support for this feature to the i40evf driver as well. In addition, a few changes are made to the i40e implementation to add function header documentation comments, as well. This behaves in a similar fashion to the implementation in i40e. Thus, requesting the moderation value when no queue is provided will report queue 0 value, while setting the value without a queue will set all queues at once.

The Tx cleanup flow was incorrectly assuming it could check for the flow director bits after it had unmapped the buffer. However in this case it results in us trying to free a raw_buf as though it is an sk_buff. To fix this I am moving up the flag test for the FD_SB bit so that when find a non-NULL skb or raw_buf value we then check the flag and use the appropriate call to free the buffer.

This patch increases minimum number of allocated VSIs, so as to resolve failure adding VSI for VF when 64-VFs assigned to a PF. The driver supports up to 128 VFs per device, users can decide to enable up to 64-VFs on a single PF, especially 2 X 40 devices. In that scenario, with VMDq co-existence, there would be starvation of VSIs - with this patch, supported features would have enough VSIs for configuration now.

In i40e_fdir_check_and_reenable(), the driver performs some checks to determine whether it is safe to re-enable FD Sideband and FD ATR support. The current check will only determine if there is available space in the flow director table. However, this ignores the fact that ATR should be disabled when there are TCP/IPv4 sideband rules in effect. Add the missing check, and update the info message printed when I40E_DEBUG_FD is enabled.

Some locations that disable ATR accidentally used the "full" disable by disabling the flag in the standard flags field. This incorrectly forces ATR off permanently instead of temporarily disabling it. In addition, some code locations accidentally set the ATR flag enabled when they only meant to clear the auto_disable_flags. This results in ignoring the user's ethtool private flag settings. Additionally, when disabling ATR via ethtool, we did not perform a flush of the FD table. This results in the previously assigned ATR rules still functioning which was not expected. Cleanup all these areas so that automatic disable uses only the auto_disable_flag. Fix the flush code so that we can trigger a flush even when we've disabled ATR and SB support, as otherwise the flush doesn't work. Fix ethtool setting to actually request a flush. Fix NETIF_F_NTUPLE flag to only clear the auto_disable setting and not enable the full feature. Change-ID: Ib2486111f8031bd16943e9308757b276305c03b5 Signed-off-by:

Add ENCAP_CSUM offload negotiation flag. Currently VF assumes checksum offload for encapsulated packets is supported by default. Going forward, this feature needs to be negotiated with PF before advertising to the stack. Hence, we need a flag to control it. This is in regards to prepping up for VF base mode functionality support. Change-ID: Iaab1f25cc0abda5f2fbe3309092640f0e77d163e Signed-off-by:

There exists a bug in which deleting a mac filter does not actually occur. The driver reports that the filter has been deleted with no error. The problem occurs because the wrong cmd_flag is passed to the firmware when deleting the filter. The firmware reports an error back to the driver but it is expressly ignored. This fixes the bug by using the correct flag when deleting a filter. Without this patch, deleted filters remain in firmware and function as if they had not been deleted.

This patch fixes the problem where driver shows 100 Mbps as a supported speed, and allows it to be configured for advertising on X722 devices. This patch fixes the problem by not setting the 100 Mbps SGMII flag for X722 devices. Without this patch, the user incorrectly thinks that 100 Mbps is supported and hence might try to advertise it on X722 devices when it is actually not a supported speed.

A future patch will modify the hook drop and outfn functions. This will cause the line lengths to take up too much space. This is simply a readability change. Signed-off-by:

Implement RxRPC slow-start, which is similar to RFC 5681 for TCP. A tracepoint is added to log the state of the congestion management algorithm and the decisions it makes. Notes: (1) Since we send fixed-size DATA packets (apart from the final packet in each phase), counters and calculations are in terms of packets rather than bytes. (2) The ACK packet carries the equivalent of TCP SACK. (3) The FLIGHT_SIZE calculation in RFC 5681 doesn't seem particularly suited to SACK of a small number of packets. It seems that, almost inevitably, by the time three 'duplicate' ACKs have been seen, we have narrowed the loss down to one or two missing packets, and the FLIGHT_SIZE calculation ends up as 2. (4) In rxrpc_resend(), if there was no data that apparently needed retransmission, we transmit a PING ACK to ask the peer to tell us what its Rx window state is. Signed-off-by:
