Convert pr_info to net_info_ratelimited to limit the total number of synflood warnings. Commit 946cedcc ("tcp: Change possible SYN flooding messages") rate limits synflood warnings to one per listener. Workloads that open many listener sockets can still see a high rate of log messages. Syzkaller is one frequent example. Signed-off-by:

Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for you net tree: 1) Remove duplicated include at the end of UDP conntrack, from Yue Haibing. 2) Restore conntrack dependency on xt_cluster, from Martin Willi. 3) Fix splat with GSO skbs from the checksum target, from Florian Westphal. 4) Rework ct timeout support, the template strategy to attach custom timeouts is not correct since it will not work in conjunction with conntrack zones and we have a possible free after use when removing the rule due to missing refcounting. To fix these problems, do not use conntrack template at all and set custom timeout on the already valid conntrack object. This fix comes with a preparation patch to simplify timeout adjustment by initializating the first position of the timeout array for all of the existing trackers. Patchset from Florian Westphal. 5) Fix missing dependency on from IPv4 chain NAT type, from Florian. 6) Release chain reference counter from the flush path, from Taehee Yoo. 7) After flushing an iptables ruleset, conntrack hooks are unregistered and entries are left stale to be cleaned up by the timeout garbage collector. No TCP tracking is done on established flows by this time. If ruleset is reloaded, then hooks are registered again and TCP tracking is restored, which considers packets to be invalid. Clear window tracking to exercise TCP flow pickup from the middle given that history is lost for us. Again from Florian. 8) Fix crash from netlink interface with CONFIG_NF_CONNTRACK_TIMEOUT=y and CONFIG_NF_CT_NETLINK_TIMEOUT=n. 9) Broken CT target due to returning incorrect type from ctnl_timeout_find_get(). 10) Solve conntrack clash on NF_REPEAT verdicts too, from Michal Vaner. 11) Missing conversion of hashlimit sysctl interface to new API, from Cong Wang. ==================== Signed-off-by:

Doug Smythies says: Sometimes it is desirable to temporarily disable, or clear, the iptables rule set on a computer being controlled via a secure shell session (SSH). While unwise on an internet facing computer, I also do it often on non-internet accessible computers while testing. Recently, this has become problematic, with the SSH session being dropped upon re-load of the rule set. The problem is that when all rules are deleted, conntrack hooks get unregistered. In case the rules are re-added later, its possible that tcp window has moved far enough so that all packets are considered invalid (out of window) until entry expires (which can take forever, default established timeout is 5 days). Fix this by clearing maxwin of existing tcp connections on register. v2: don't touch entries on hook removal. v3: remove obsolete expiry check. Reported-by:

Quectel EP06 (and EM06/EG06) supports dynamic configuration of USB interfaces, without the device changing VID/PID or configuration number. When the configuration is updated and interfaces are added/removed, the interface numbers change. This means that the current code for matching EP06 does not work. This patch removes the current EP06 interface number match, and replaces it with a match on class, subclass and protocol. Unfortunately, matching on those three alone is not enough, as the diag interface exports the same values as QMI. The other serial interfaces + adb export different values and do not match. The diag interface only has two endpoints, while the QMI interface has three. I have therefore added a check for number of interfaces, and we ignore the interface if the number of endpoints equals two. Signed-off-by:

tls_sw_sendmsg() allocates plaintext and encrypted SG entries using function sk_alloc_sg(). In case the number of SG entries hit MAX_SKB_FRAGS, sk_alloc_sg() returns -ENOSPC and sets the variable for current SG index to '0'. This leads to calling of function tls_push_record() with 'sg_encrypted_num_elem = 0' and later causes kernel crash. To fix this, set the number of SG elements to the number of elements in plaintext/encrypted SG arrays in case sk_alloc_sg() returns -ENOSPC. Fixes: 3c4d7559 ("tls: kernel TLS support") Signed-off-by:

Netanel Belgazal authored
When ena_destroy_device() is called from ena_suspend(), the device is still reachable from the driver. Therefore, the driver can send a command to the device to free all resources. However, in all other cases of calling ena_destroy_device(), the device is potentially in an error state and unreachable from the driver. In these cases the driver must not send commands to the device. The current implementation does not request resource freeing from the device even when possible. We add the graceful parameter to ena_destroy_device() to enable resource freeing when possible, and use it in ena_suspend(). Signed-off-by:

The buffer length field in the ena rx descriptor is 16 bit, and the current driver passes a full page in each ena rx descriptor. When PAGE_SIZE equals 64kB or more, the buffer length field becomes zero. To solve this issue, limit the ena Rx descriptor to use 16kB even when allocating 64kB kernel pages. This change would not impact ena device functionality, as 16kB is still larger than maximum MTU. Signed-off-by:

According to the documentation in msg_zerocopy.rst, the SO_ZEROCOPY flag was introduced because send(2) ignores unknown message flags and any legacy application which was accidentally passing the equivalent of MSG_ZEROCOPY earlier should not see any new behaviour. Before commit f214f915 ("tcp: enable MSG_ZEROCOPY"), a send(2) call which passed the equivalent of MSG_ZEROCOPY without setting SO_ZEROCOPY would succeed. However, after that commit, it fails with -ENOBUFS. So it appears that the SO_ZEROCOPY flag fails to fulfill its intended purpose. Fix it. Fixes: f214f915 ("tcp: enable MSG_ZEROCOPY") Signed-off-by:

Commit 822fb18a ("xen-netfront: wait xenbus state change when load module manually") added a new wait queue to wait on for a state change when the module is loaded manually. Unfortunately there is no wakeup anywhere to stop that waiting. Instead of introducing a new wait queue rename the existing module_unload_q to module_wq and use it for both purposes (loading and unloading). As any state change of the backend might be intended to stop waiting do the wake_up_all() in any case when netback_changed() is called.

Commit 3559d81e ("r8169: simplify rtl_hw_start_8169") changed order of two register writes: 1) Caused RxConfig to be written before TX / RX is enabled, 2) Caused TxConfig to be written before TX / RX is enabled. At least on XIDs 10000000 ("RTL8169sb/8110sb") and 18000000 ("RTL8169sc/8110sc") such writes are ignored by the chip, leaving values in these registers intact. Change 1) was reverted by commit 05212ba8 ("r8169: set RxConfig after tx/rx is enabled for RTL8169sb/8110sb devices"), however change 2) wasn't. In practice, this caused TxConfig's "InterFrameGap time" and "Max DMA Burst Size per Tx DMA Burst" bits to be zero dramatically reducing TX performance (in my tests it dropped from around 500Mbps to around 50Mbps). This patch fixes the issue by moving TxConfig register write a bit later in the code so it happens after TX / RX is already enabled.

__tipc_nl_compat_dumpit() uses a netlink_callback on stack, so the only way to align it with other ->dumpit() call path is calling tipc_dump_start() and tipc_dump_done() directly inside it. Otherwise ->dumpit() would always get NULL from cb->args[]. But tipc_dump_start() uses sock_net(cb->skb->sk) to retrieve net pointer, the cb->skb here doesn't set skb->sk, the net pointer is saved in msg->net instead, so introduce a helper function __tipc_dump_start() to pass in msg->net. Ying pointed out cb->args[0...3] are already used by other callbacks on this call path, so we can't use cb->args[0] any more, use cb->args[4] instead.

When sending an skb, afiucv_hs_send() bails out on various error conditions. But currently the caller has no way of telling whether the skb was freed or not - resulting in potentially either a) leaked skbs from iucv_send_ctrl(), or b) double-free's from iucv_sock_sendmsg(). As dev_queue_xmit() will always consume the skb (even on error), be consistent and also free the skb from all other error paths. This way callers no longer need to care about managing the skb.

Before we unlock the sock in tipc_release(), we have to detach sk->sk_socket from sk, otherwise a parallel tipc_sk_fill_sock_diag() could stil read it after we free this socket.

This is a false positive report due to incorrect nested lock annotations as we lock multiple fgs with the same subclass. Instead of locking all fgs only lock the one being used as was done before. Fixes: bd71b08e ("net/mlx5: Support multiple updates of steering rules in parallel") Signed-off-by:

Currently, mlx5_attach_interface does not check for error after calling intf->attach or intf->add. When these two calls fails, the client is not initialized and will cause issues such as kernel panic on invalid address in the teardown path (mlx5_detach_interface) Fixes: 737a234b ("net/mlx5: Introduce attach/detach to interface API") Signed-off-by:

The PCI BDF is not unique. PCI domain must also be considered when searching for the next physical device during lag setup.
