2023-02-27tcp: tcp_check_req() can be called from process contextEric Dumazet
This is a follow up of commit 0a375c822497 ("tcp: tcp_rtx_synack() can be called from process context"). Frederick Lawler reported another "__this_cpu_add() in preemptible" warning caused by the same reason. In my former patch I took care of tcp_rtx_synack() but forgot that tcp_check_req() also contained some SNMP updates. Note that some parts of tcp_check_req() always run in BH context, I added a comment to clarify this.

2023-02-26wifi: wext: warn about usage only onceJohannes Berg
Warn only once since the ratelimit parameters are still allowing too many messages to happen. This will no longer tell you all the different processes, but still gives a heads-up of sorts. Also modify the message to note that wext stops working for future Wi-Fi 7 hardware, this is already implemented in commit 4ca69027691a ("wifi: wireless: deny wireless extensions on MLO-capable devices") and is maybe of more relevance to users than the fact that we'd like to have wireless extensions deprecated. The issue with Wi-Fi 7 is that you can now have multiple connections to the same AP, so a whole bunch of things now become per link rather than per netdev, which can't really be handled in wireless extensions.

2023-02-26nfc: fix memory leak of se_io context in nfc_genl_se_ioFedor Pchelkin
The callback context for sending/receiving APDUs to/from the selected secure element is allocated inside nfc_genl_se_io and supposed to be eventually freed in se_io_cb callback function. However, there are several error paths where the bwi_timer is not charged to call se_io_cb later, and the cb_context is leaked. The patch proposes to free the cb_context explicitly on those error paths. At the moment we can't simply check 'dev->ops->se_io()' return value as it may be negative in both cases: when the timer was charged and was not.

Its single callsite is in an '#ifdef CONFIG_NET_CLS_ACT' block but a definition will always be present in the file. The version of tcf_exts_miss_cookie_base_destroy() that actually does something depends on CONFIG_NET_TC_SKB_EXT, so the stub function is used in both CONFIG_NET_CLS_ACT=n and CONFIG_NET_CLS_ACT=y + CONFIG_NET_TC_SKB_EXT=n configurations. Move the call to tcf_exts_miss_cookie_base_destroy() in tcf_exts_destroy() out of the '#ifdef CONFIG_NET_CLS_ACT', so that it always appears used to the compiler, while not changing any behavior with any of the various configuration combinations.

2023-02-249p/xen: fix connection sequenceJuergen Gross
Today the connection sequence of the Xen 9pfs frontend doesn't match the documented sequence. It can work reliably only for a PV 9pfs device having been added at boot time already, as the frontend is not waiting for the backend to have set its state to "XenbusStateInitWait" before reading the backend properties from Xenstore. Fix that by following the documented sequence [1] (the documentation has a bug, so the reference is for the patch fixing that).

2023-02-249p/xen: fix version parsingJuergen Gross
When connecting the Xen 9pfs frontend to the backend, the "versions" Xenstore entry written by the backend is parsed in a wrong way. The "versions" entry is defined to contain the versions supported by the backend separated by commas (e.g. "1,2"). Today only version "1" is defined. Unfortunately the frontend doesn't look for "1" being listed in the entry, but it is expecting the entry to have the value "1". This will result in failure as soon as the backend will support e.g. versions "1" and "2". Fix that by scanning the entry correctly.

dev_kfree_skb() is aliased to consume_skb(). When a driver is dropping a packet by calling dev_kfree_skb_any() we should propagate the drop reason instead of pretending the packet was consumed.

This provides a clean path for deprecating and removing insecure encryption types based on DES and SHA-1.

Split the code into multiple files, drop some of the unnecessarily granular locks and factor out common parts of netlink operation handling. - Add TX frame aggregation parameters (for USB drivers). - Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning messages with notifications for debug. - Allow offloading of UDP NEW connections via act_ct. - Add support for per action HW stats in TC. - Support hardware miss to TC action (continue processing in SW from a specific point in the action chain). - Warn if old Wireless Extension user space interface is used with modern cfg80211/mac80211 drivers. Do not support Wireless Extensions for Wi-Fi 7 devices at all. Everyone should switch to using nl80211 interface instead. - Improve the CAN bit timing configuration. Use extack to return error messages directly to user space, update the SJW handling, including the definition of a new default value that will benefit CAN-FD controllers, by increasing their oscillator tolerance.

2023-02-22netfilter: ctnetlink: make event listener tracking globalFlorian Westphal
pernet tracking doesn't work correctly because other netns might have set NETLINK_LISTEN_ALL_NSID on its event socket. In this case its expected that events originating in other net namespaces are also received. Making pernet-tracking work while also honoring NETLINK_LISTEN_ALL_NSID requires much more intrusive changes both in netlink and nfnetlink, f.e. adding a 'setsockopt' callback that lets nfnetlink know that the event socket entered (or left) ALL_NSID mode. Move to global tracking instead: if there is an event socket anywhere on the system, all net namespaces which have conntrack enabled and use autobind mode will allocate the ecache extension. netlink_has_listeners() returns false only if the given group has no subscribers in any net namespace, the 'net' argument passed to nfnetlink_has_listeners is only used to derive the protocol (nfnetlink), it has no other effect. For proper NETLINK_LISTEN_ALL_NSID-aware pernet tracking of event listeners a new netlink_has_net_listeners() is also needed.

2023-02-22netfilter: xt_length: use skb len to match in length_mt6Xin Long
For IPv6 Jumbo packets, the ipv6_hdr(skb)->payload_len is always 0, and its real payload_len ( > 65535) is saved in hbh exthdr. With 0 length for the jumbo packets, it may mismatch. To fix this, we can just use skb->len instead of parsing exthdrs, as the hbh exthdr parsing has been done before coming to length_mt6 in ip6_rcv_core() and br_validate_ipv6() and also the packet has been trimmed according to the correct IPv6 (ext)hdr length there, and skb len is trustable in length_mt6(). Note that this patch is especially needed after the IPv6 BIG TCP was supported in kernel, which is using IPv6 Jumbo packets. Besides, to match the packets greater than 65535 more properly, a v1 revision of xt_length may be needed to extend "min, max" to u32 in the future, and for now the IPv6 Jumbo packets can be matched by: # ip6tables -m length ! --length 0:65535 Fixes: 7c4e983c4f3c ("net: allow gso_max_size to exceed 65536") Fixes: 0fe79f28bfaf ("net: allow gro_max_size to exceed 65536") Signed-off-by: Xin Long <lucien.xin@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2023-02-22netfilter: conntrack: fix rmmod double-free raceFlorian Westphal
nf_conntrack_hash_check_insert() callers free the ct entry directly, via nf_conntrack_free. This isn't safe anymore because nf_conntrack_hash_check_insert() might place the entry into the conntrack table and then delteted the entry again because it found that a conntrack extension has been removed at the same time. In this case, the just-added entry is removed again and an error is returned to the caller. Problem is that another cpu might have picked up this entry and incremented its reference count. This results in a use-after-free/double-free, once by the other cpu and once by the caller of nf_conntrack_hash_check_insert(). Fix this by making nf_conntrack_hash_check_insert() not fail anymore after the insertion, just like before the 'Fixes' commit. This is safe because a racing nf_ct_iterate() has to wait for us to release the conntrack hash spinlocks. While at it, make the function return -EAGAIN in the rmmod (genid changed) case, this makes nfnetlink replay the command (suggested by Pablo Neira).

For drivers to support partial offload of a filter's action list, add support for action miss to specify an action instance to continue from in sw. CT action in particular can't be fully offloaded, as new connections need to be handled in software. This imposes other limitations on the actions that can be offloaded together with the CT action, such as packet modifications. Assign each action on a filter's action list a unique miss_cookie which drivers can then use to fill action_miss part of the tc skb extension. On getting back this miss_cookie, find the action instance with relevant cookie and continue classifying from there.
