Four years ago we introduced a new sysctl knob to disable automatic helper assignment in 72110dfaa907 ("netfilter: nf_ct_helper: disable automatic helper assignment"). This knob kept this behaviour enabled by default to remain conservative. This measure was introduced to provide a secure way to configure iptables and connection tracking helpers through explicit rules. Give the time we have waited for this, let's turn off this by default now, worse case users still have a chance to recover the former behaviour by explicitly enabling this back through sysctl.

This patch fixes dynamic element updates for adjacent intervals in the rb-tree representation. Since elements are sorted in the rb-tree, in case of adjacent nodes with the same key, the assumption is that an interval end node must be placed before an interval opening. In tree lookup operations, the idea is to search for the closer element that is smaller than the one we're searching for. Given that we'll have two possible matchings, we have to take the opening interval in case of adjacent nodes. Range merges are not trivial with the current representation, specifically we have to check if node extensions are equal and make sure we keep the existing internal states around. Signed-off-by:

We only allow rehash in init namespace, so we only use init_ns.generation. And even if we would allow it, it makes no sense as the conntrack locks are global; any ongoing rehash prevents insert/ delete. So make this private to nf_conntrack_core instead. Signed-off-by:

Linux TCP stack painfully segments all TSO/GSO packets before retransmits. This was fine back in the days when TSO/GSO were emerging, with their bugs, but we believe the dark age is over. Keeping big packets in write queues, but also in stack traversal has a lot of benefits. - Less memory overhead, because write queues have less skbs - Less cpu overhead at ACK processing. - Better SACK processing, as lot of studies mentioned how awful linux was at this ;) - Less cpu overhead to send the rtx packets (IP stack traversal, netfilter traversal, drivers...) - Better latencies in presence of losses. - Smaller spikes in fq like packet schedulers, as retransmits are not constrained by TCP Small Queues. 1 % packet losses are common today, and at 100Gbit speeds, this translates to ~80,000 losses per second. Losses are often correlated, and we see many retransmit events leading to 1-MSS train of packets, at the time hosts are already under stress. Signed-off-by:

Commit 42b18f60 ("tipc: refactor function tipc_link_timeout()"), introduced a bug which prevents sending of probe messages during link synchronization phase. This leads to hanging links, if the bearer is disabled/enabled after links are up. In this commit, we send the probe messages correctly.

When a tcp skb is sliced into two smaller skbs (e.g. in tcp_fragment() and tso_fragment()), it does not carry the txstamp_ack bit to the newly created skb if it is needed. The end result is a timestamping event (SCM_TSTAMP_ACK) will be missing from the sk->sk_error_queue. This patch carries this bit to the new skb2 in tcp_fragment_tstamp().

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for your net-next tree, mostly from Florian Westphal to sort out the lack of sufficient validation in x_tables and connlabel preparation patches to add nf_tables support. They are: 1) Ensure we don't go over the ruleset blob boundaries in mark_source_chains(). 2) Validate that target jumps land on an existing xt_entry. This extra sanitization comes with a performance penalty when loading the ruleset. 3) Introduce xt_check_entry_offsets() and use it from {arp,ip,ip6}tables. 4) Get rid of the smallish check_entry() functions in {arp,ip,ip6}tables. 5) Make sure the minimal possible target size in x_tables. 6) Similar to #3, add xt_compat_check_entry_offsets() for compat code. 7) Check that standard target size is valid. 8) More sanitization to ensure that the target_offset field is correct. 9) Add xt_check_entry_match() to validate that matches are well-formed. 10-12) Three patch to reduce the number of parameters in translate_compat_table() for {arp,ip,ip6}tables by using a container structure. 13) No need to return value from xt_compat_match_from_user(), so make it void. 14) Consolidate translate_table() so it can be used by compat code too. 15) Remove obsolete check for compat code, so we keep consistent with what was already removed in the native layout code (back in 2007). 16) Get rid of target jump validation from mark_source_chains(), obsoleted by #2. 17) Introduce xt_copy_counters_from_user() to consolidate counter copying, and use it from {arp,ip,ip6}tables. 18,22) Get rid of unnecessary explicit inlining in ctnetlink for dump functions. 19) Move nf_connlabel_match() to xt_connlabel. 20) Skip event notification if connlabel did not change. 21) Update of nf_connlabels_get() to make the upcoming nft connlabel support easier. 23) Remove spinlock to read protocol state field in conntrack. ==================== Signed-off-by:

With commit 8bc2a407 ("rtc: ds1307: add support for the DT property 'wakeup-source'") we lost the ability for rtc irq functionality for devices that are actually hooked on a real IRQ line and have capability to wakeup as well. This is not an expected behavior. So, instead of just not requesting IRQ, skip the IRQ requirement only if interrupts are not defined for the device.

Currently all drivers depend and autoload the vxlan module because how vxlan_get_rx_port is linked into them. Remove this dependency: By using a new event type in the netdevice notifier call chain we proxy the request from the drivers to flush and resetup the vxlan ports not directly via function call but by the already existing netdevice notifier call chain. I added a separate new event type, NETDEV_OFFLOAD_PUSH_VXLAN, to do so. We don't need to save those ids, as the event type field is an unsigned long and using specialized event types for this purpose seemed to be a more elegant way. This also comes in beneficial if in future we want to add offloading knobs for vxlan. Cc: Jesse Gross <jesse@kernel.org> Signed-off-by:

When using masked actions the ipv6_proto field of an action to set IPv6 fields may be zero rather than the prevailing protocol which will result in skipping checksum recalculation. This patch resolves the problem by relying on the protocol in the flow key rather than that in the set field action. Fixes: 83d2b9ba ("net: openvswitch: Support masked set actions.")
