2021-03-31netfilter: nf_log_ipv6: merge with nf_log_syslogFlorian Westphal
This removes the nf_log_ipv6 module, the functionality is now provided by nf_log_syslog. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2021-03-31netfilter: nf_log_arp: merge with nf_log_syslogFlorian Westphal
similar to previous change: nf_log_syslog now covers ARP logging as well, the old nf_log_arp module is removed. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2021-03-31netfilter: nf_log_ipv4: rename to nf_log_syslogFlorian Westphal
Netfilter has multiple log modules: nf_log_arp nf_log_bridge nf_log_ipv4 nf_log_ipv6 nf_log_netdev nfnetlink_log nf_log_common With the exception of nfnetlink_log (packet is sent to userspace for dissection/logging), all of them log to the kernel ringbuffer. This is the first part of a series to merge all modules except nfnetlink_log into a single module: nf_log_syslog. This allows to reduce code. After the series, only two log modules remain: nfnetlink_log and nf_log_syslog. The latter provides the same functionality as the old per-af log modules. This renames nf_log_ipv4 to nf_log_syslog.

2021-03-30net: let skb_orphan_partial wake-up waiters.Paolo Abeni
Currently the mentioned helper can end-up freeing the socket wmem without waking-up any processes waiting for more write memory. If the partially orphaned skb is attached to an UDP (or raw) socket, the lack of wake-up can hang the user-space. Even for TCP sockets not calling the sk destructor could have bad effects on TSQ. Address the issue using skb_orphan to release the sk wmem before setting the new sock_efree destructor. Additionally bundle the whole ownership update in a new helper, so that later other potential users could avoid duplicate code. v1 -> v2: - use skb_orphan() instead of sort of open coding it (Eric) - provide an helper for the ownership change (Eric) Fixes: f6ba8d33cfbb ("netem: fix skb_orphan_partial()") Suggested-by: Eric Dumazet <edumazet@google.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com> Reviewed-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2021-03-30icmp: add response to RFC 8335 PROBE messagesAndreas Roeseler
Modify the icmp_rcv function to check PROBE messages and call icmp_echo if a PROBE request is detected. Modify the existing icmp_echo function to respond ot both ping and PROBE requests. This was tested using a custom modification to the iputils package and wireshark. It supports IPV4 probing by name, ifindex, and probing by both IPV4 and IPV6 addresses. It currently does not support responding to probes off the proxy node (see RFC 8335 Section 2). The modification to the iputils package is still in development and can be found here: https://github.com/Juniper-Clinic-2020/iputils.git. It supports full sending functionality of PROBE requests, but currently does not parse the response messages, which is why Wireshark is required to verify the sent and recieved PROBE messages. The modification adds the ``-e'' flag to the command which allows the user to specify the interface identifier to query the probed host. An example usage would be <./ping -4 -e 1 [destination]> to send a PROBE request of ifindex 1 to the destination node.

2021-03-30net: sched: bump refcount for new action in ACT replace modeKumar Kartikeya Dwivedi
Currently, action creation using ACT API in replace mode is buggy. When invoking for non-existent action index 42, tc action replace action bpf obj foo.o sec <xyz> index 42 kernel creates the action, fills up the netlink response, and then just deletes the action after notifying userspace. tc action show action bpf doesn't list the action. This happens due to the following sequence when ovr = 1 (replace mode) is enabled: tcf_idr_check_alloc is used to atomically check and either obtain reference for existing action at index, or reserve the index slot using a dummy entry (ERR_PTR(-EBUSY)). This is necessary as pointers to these actions will be held after dropping the idrinfo lock, so bumping the reference count is necessary as we need to insert the actions, and notify userspace by dumping their attributes. Finally, we drop the reference we took using the tcf_action_put_many call in tcf_action_add. However, for the case where a new action is created due to free index, its refcount remains one. This when paired with the put_many call leads to the kernel setting up the action, notifying userspace of its creation, and then tearing it down. For existing actions, the refcount is still held so they remain unaffected. Fortunately due to rtnl_lock serialization requirement, such an action with refcount == 1 will not be concurrently deleted by anything else, at best CLS API can move its refcount up and down by binding to it after it has been published from tcf_idr_insert_many. Since refcount is atleast one until put_many call, CLS API cannot delete it. Also __tcf_action_put release path already ensures deterministic outcome (either new action will be created or existing action will be reused in case CLS API tries to bind to action concurrently) due to idr lock serialization. We fix this by making refcount of newly created actions as 2 in ACT API replace mode. A relaxed store will suffice as visibility is ensured only after the tcf_idr_insert_many call. Note that in case of creation or overwriting using CLS API only (i.e. bind = 1), overwriting existing action object is not allowed, and any such request is silently ignored (without error). The refcount bump that occurs in tcf_idr_check_alloc call there for existing action will pair with tcf_exts_destroy call made from the owner module for the same action. In case of action creation, there is no existing action, so no tcf_exts_destroy callback happens. This means no code changes for CLS API.

2021-03-30net/ncsi: Avoid channel_monitor hrtimer deadlockMilton Miller
Calling ncsi_stop_channel_monitor from channel_monitor is a guaranteed deadlock on SMP because stop calls del_timer_sync on the timer that invoked channel_monitor as its timer function. Recognise the inherent race of marking the monitor disabled before deleting the timer by just returning if enable was cleared. After a timeout (the default case -- reset to START when response received) just mark the monitor.enabled false. If the channel has an entry on the channel_queue list, or if the state is not ACTIVE or INACTIVE, then warn and mark the timer stopped and don't restart, as the locking is broken somehow.

2021-03-29bpf: tcp: Limit calling some tcp cc functions to CONFIG_DYNAMIC_FTRACEMartin KaFai Lau
pahole currently only generates the btf_id for external function and ftrace-able function. Some functions in the bpf_tcp_ca_kfunc_ids are static (e.g. cubictcp_init). Thus, unless CONFIG_DYNAMIC_FTRACE is set, btf_ids for those functions will not be generated and the compilation fails during resolve_btfids. This patch limits those functions to CONFIG_DYNAMIC_FTRACE. I will address the pahole generation in a followup and then remove the CONFIG_DYNAMIC_FTRACE limitation.

2021-03-29can: isotp: fix msg_namelen values depending on CAN_REQUIRED_SIZEOliver Hartkopp
Since commit f5223e9eee65 ("can: extend sockaddr_can to include j1939 members") the sockaddr_can has been extended in size and a new CAN_REQUIRED_SIZE macro has been introduced to calculate the protocol specific needed size. The ABI for the msg_name and msg_namelen has not been adapted to the new CAN_REQUIRED_SIZE macro for the other CAN protocols which leads to a problem when an existing binary reads the (increased) struct sockaddr_can in msg_name.

2021-03-29xfrm: Provide private skb extensions for segmented and hw offloaded ESP packetsSteffen Klassert
Commit 94579ac3f6d0 ("xfrm: Fix double ESP trailer insertion in IPsec crypto offload.") added a XFRM_XMIT flag to avoid duplicate ESP trailer insertion on HW offload. This flag is set on the secpath that is shared amongst segments. This lead to a situation where some segments are not transformed correctly when segmentation happens at layer 3. Fix this by using private skb extensions for segmented and hw offloaded ESP packets. Fixes: 94579ac3f6d0 ("xfrm: Fix double ESP trailer insertion in IPsec crypto offload.")

2021-03-28nexthop: Rename artifacts related to legacy multipath nexthop groupsPetr Machata
After resilient next-hop groups have been added recently, there are two types of multipath next-hop groups: the legacy "mpath", and the new "resilient". Calling the legacy next-hop group type "mpath" is unfortunate, because that describes the fact that a packet could be forwarded in one of several paths, which is also true for the resilient next-hop groups. Therefore, to make the naming clearer, rename various artifacts to reflect the assumptions made. Therefore as of this patch: - The flag for multipath groups is nh_grp_entry::is_multipath. This includes the legacy and resilient groups, as well as any future group types that behave as multipath groups. Functions that assume this have "mpath" in the name. - The flag for legacy multipath groups is nh_grp_entry::hash_threshold. Functions that assume this have "hthr" in the name. - The flag for resilient groups is nh_grp_entry::resilient. Functions that assume this have "res" in the name. Besides the above, struct nh_grp_entry::mpath was renamed to ::hthr as well. UAPI artifacts were obviously left intact.
