* scripts/spelling.txt: add "an user" pattern and fix typo instancesMasahiro Yamada2017-02-271-2/+2
| | | | | | | | | | | | | | | | | Fix typos and add the following to the scripts/spelling.txt: an user||a user an userspace||a userspace I also added "userspace" to the list since it is a common word in Linux. I found some instances for "an userfaultfd", but I did not add it to the list. I felt it is endless to find words that start with "user" such as "userland" etc., so must draw a line somewhere.

Patchset from Florian Westphal. 2) Don't leak pointer to internal structures when exporting x_tables ruleset back to userspace, from Willem DeBruijn. This includes new helper functions to copy data to userspace such as xt_data_to_user() as well as conversions of our ip_tables, ip6_tables and arp_tables clients to use it. Not surprinsingly, ebtables requires an ad-hoc update. There is also a new field in x_tables extensions to indicate the amount of bytes that we copy to userspace. 3) Add nf_log_all_netns sysctl: This new knob allows you to enable logging via nf_log infrastructure for all existing netnamespaces. Given the effort to provide pernet syslog has been discontinued, let's provide a way to restore logging using netfilter kernel logging facilities in trusted environments. Patch from Michal Kubecek. 4) Validate SCTP checksum from conntrack helper, from Davide Caratti. 5) Merge UDPlite conntrack and NAT helpers into UDP, this was mostly a copy&paste from the original helper, from Florian Westphal. 6) Reset netfilter state when duplicating packets, also from Florian. 7) Remove unnecessary check for broadcast in IPv6 in pkttype match and nft_meta, from Liping Zhang. 8) Add missing code to deal with loopback packets from nft_meta when used by the netdev family, also from Liping. 9) Several cleanups on nf_tables, one to remove unnecessary check from the netlink control plane path to add table, set and stateful objects and code consolidation when unregister chain hooks, from Gao Feng. 10) Fix harmless reference counter underflow in IPVS that, however, results in problems with the introduction of the new refcount_t type, from David Windsor. 11) Enable LIBCRC32C from nf_ct_sctp instead of nf_nat_sctp, from Davide Caratti. 12) Missing documentation on nf_tables uapi header, from Liping Zhang. 13) Use rb_entry() helper in xt_connlimit, from Geliang Tang. ==================== Signed-off-by: David S.

| * | netfilter: allow logging from non-init namespacesMichal Kubeček2017-02-021-0/+10
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 69b34fb996b2 ("netfilter: xt_LOG: add net namespace support for xt_LOG") disabled logging packets using the LOG target from non-init namespaces. The motivation was to prevent containers from flooding kernel log of the host. The plan was to keep it that way until syslog namespace implementation allows containers to log in a safe way. However, the work on syslog namespace seems to have hit a dead end somewhere in 2013 and there are users who want to use xt_LOG in all network namespaces. This patch allows to do so by setting /proc/sys/net/netfilter/nf_log_all_netns to a nonzero value. This sysctl is only accessible from init_net so that one cannot switch the behaviour from inside a container.

* | net: Avoid receiving packets with an l3mdev on unbound UDP socketsRobert Shearman2017-01-302-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Packets arriving in a VRF currently are delivered to UDP sockets that aren't bound to any interface. TCP defaults to not delivering packets arriving in a VRF to unbound sockets. IP route lookup and socket transmit both assume that unbound means using the default table and UDP applications that haven't been changed to be aware of VRFs may not function correctly in this case since they may not be able to handle overlapping IP address ranges, or be able to send packets back to the original sender if required. So add a sysctl, udp_l3mdev_accept, to control this behaviour with it being analgous to the existing tcp_l3mdev_accept, namely to allow a process to have a VRF-global listen socket. Have this default to off as this is the behaviour that users will expect, given that there is no explicit mechanism to set unmodified VRF-unaware application into a default VRF.

* | Introduce a sysctl that modifies the value of PROT_SOCK.Krister Johansen2017-01-241-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add net.ipv4.ip_unprivileged_port_start, which is a per namespace sysctl that denotes the first unprivileged inet port in the namespace. To disable all privileged ports set this to zero. It also checks for overlap with the local port range. The privileged and local range may not overlap. The use case for this change is to allow containerized processes to bind to priviliged ports, but prevent them from ever being allowed to modify their container's network configuration. The latter is accomplished by ensuring that the network namespace is not a child of the user namespace. This modification was needed to allow the container manager to disable a namespace's priviliged port restrictions without exposing control of the network namespace to processes in the user namespace.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Thin stream DUPACK is to start fast recovery on only one DUPACK provided the connection is a thin stream (i.e., low inflight). But this older feature is now subsumed with RACK. If a connection receives only a single DUPACK, RACK would arm a reordering timer and soon starts fast recovery instead of timeout if no further ACKs are received. The socket option (THIN_DUPACK) is kept as a nop for compatibility. Note that this patch does not change another thin-stream feature which enables linear RTO. Although it might be good to generalize that in the future (i.e., linear RTO for the first say 3 retries).

More specifically when RACK receives DUPACKs, it'll arm a reordering timer to start fast recovery after a quarter of (min)RTT, hence it covers the early retransmit except RACK does not limit itself to specific inflight or dupack numbers.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Although TPACKET_V3 Rx has some benefits over TPACKET_V2 Rx, *_v3 does not currently have TX_RING support. As a result an application that wants the best perf for Tx and Rx (e.g. to handle request/response transacations) ends up needing 2 sockets, one with *_v2 for Tx and another with *_v3 for Rx. This patch enables TPACKET_V2 compatible Tx features in TPACKET_V3 so that an application can use a single descriptor to get the benefits of _v3 RX_RING and _v2 TX_RING. An application may do a block-send by first filling up multiple frames in the Tx ring and then triggering a transmit. This patch only support fixed size Tx frames for TPACKET_V3, and requires that tp_next_offset must be zero. Signed-off-by: Sowmini Varadhan <sowmini.varadhan@oracle.com> Signed-off-by: David S.

This series provides a nf_tables native alternative to the extended accounting infrastructure for nf_tables. Two initial stateful objects are supported: counters and quotas. Objects are identified by a user-defined name, you can fetch and reset them anytime. You can also use a maps to allow fast lookups using any arbitrary key combination. More info at: http://marc.info/?l=netfilter-devel&m=148029128323837&w=2 2) On-demand registration of nf_conntrack and defrag hooks per netns. Register nf_conntrack hooks if we have a stateful ruleset, ie. state-based filtering or NAT. The new nf_conntrack_default_on sysctl enables this from newly created netnamespaces. Default behaviour is not modified. Patches from Florian Westphal. 3) Allocate 4k chunks and then use these for x_tables counter allocation requests, this improves ruleset load time and also datapath ruleset evaluation, patches from Florian Westphal. 4) Add support for ebpf to the existing x_tables bpf extension. From Willem de Bruijn. 5) Update layer 4 checksum if any of the pseudoheader fields is updated. This provides a limited form of 1:1 stateless NAT that make sense in specific scenario, eg. load balancing. 6) Add support to flush sets in nf_tables. This series comes with a new set->ops->deactivate_one() indirection given that we have to walk over the list of set elements, then deactivate them one by one. The existing set->ops->deactivate() performs an element lookup that we don't need. 7) Two patches to avoid cloning packets, thus speed up packet forwarding via nft_fwd from ingress. From Florian Westphal. 8) Two IPVS patches via Simon Horman: Decrement ttl in all modes to prevent infinite loops, patch from Dwip Banerjee. And one minor refactoring from Gao feng. 9) Revisit recent log support for nf_tables netdev families: One patch to ensure that we correctly handle non-ethernet packets. Another patch to add missing logger definition for netdev. Patches from Liping Zhang. 10) Three patches for nft_fib, one to address insufficient register initialization and another to solve incorrect (although harmless) byteswap operation. Moreover update xt_rpfilter and nft_fib to match lbcast packets with zeronet as source, eg. DHCP Discover packets (0.0.0.0 -> 255.255.255.255). Also from Liping Zhang. 11) Built-in DCCP, SCTP and UDPlite conntrack and NAT support, from Davide Caratti. While DCCP is rather hopeless lately, and UDPlite has been broken in many-cast mode for some little time, let's give them a chance by placing them at the same level as other existing protocols. Thus, users don't explicitly have to modprobe support for this and NAT rules work for them. Some people point to the lack of support in SOHO Linux-based routers that make deployment of new protocols harder. I guess other middleboxes outthere on the Internet are also to blame. Anyway, let's see if this has any impact in the midrun. 12) Skip software SCTP software checksum calculation if the NIC comes with SCTP checksum offload support. From Davide Caratti. 13) Initial core factoring to prepare conversion to hook array. Three patches from Aaron Conole. 14) Gao Feng made a wrong conversion to switch in the xt_multiport extension in a patch coming in the previous batch. Fix it in this batch. 15) Get vmalloc call in sync with kmalloc flags to avoid a warning and likely OOM killer intervention from x_tables. From Marcelo Ricardo Leitner. 16) Update Arturo Borrero's email address in all source code headers. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

This means that when net namespace goes down (or the tracker protocol module is unloaded) we *might* have to unregister the hooks. We can either add another per-netns variable that tells if the hooks got registered by default, or, alternatively, just call the protocol _put() function and have the callee deal with a possible 'extra' put() operation that doesn't pair with a get() one. This uses the latter approach, i.e. a put() without a get has no effect. Conntrack is still enabled automatically regardless of the new sysctl setting if the new net namespace requires connection tracking, e.g. when NAT rules are created.

IPv6 duplicate address detection can fail if there is some temporary loopback of Ethernet frames. RFC7527 solves this by including a random nonce in the NS messages used for DAD, and if an NS is received with the same nonce it is assumed to be a looped back DAD probe and is ignored. RFC7527 is enabled by default. Can be disabled by setting both of conf/{all,interface}/enhanced_dad to zero.

It also overlapped with Jiri's change to guard the rhashtable_remove_fast() call with a check against tc_skip_sw(). 5) In mlx4, a revert bug fix in 'net' overlapped with some unrelated changes in 'net-next'. 6) In geneve, a stale header pointer after pskb_expand_head() bug fix in 'net' overlapped with a large reorganization of the same code in 'net-next'. Since the 'net-next' code no longer had the bug in question, there was nothing to do other than to simply take the 'net-next' hunks. Signed-off-by: David S. Miller <davem@davemloft.net>

Currently we can instrument how long a particular application unit of data was queued in TCP by tracking SOF_TIMESTAMPING_TX_SOFTWARE and SOF_TIMESTAMPING_TX_SCHED. Having these sender chronograph stats exported simultaneously along with these timestamps allow further breaking down the various sender limitation. For example, a video server can tell if a particular chunk of video on a connection takes a long time to deliver because TCP was experiencing small receive window. It is not possible to tell before this patch without packet traces. To prepare these stats, the user needs to set SOF_TIMESTAMPING_OPT_STATS and SOF_TIMESTAMPING_OPT_TSONLY flags while requesting other SOF_TIMESTAMPING TX timestamps. When the timestamps are available in the error queue, the stats are returned in a separate control message of type SCM_TIMESTAMPING_OPT_STATS, in a list of TLVs (struct nlattr) of types: TCP_NLA_BUSY_TIME, TCP_NLA_RWND_LIMITED, TCP_NLA_SNDBUF_LIMITED. Unit is microsecond.
