This commit adds support for the ufi-001C and uf896 WiFi/LTE dongle made by Tong Heng Wei Chuang based on MSM8916. uf896 is another variant for the usb stick. The board design differs by using different gpios for the keys and leds. Note: The original firmware does not support 64-bit OS. It is necessary to flash 64-bit TZ firmware to boot arm64.

Commit 3bc753c06dd0 ("kbuild: treat char as always unsigned") broke kprobes. Setting a probe-point on 1 byte conditional jump can cause the kernel to crash when the (signed) relative jump offset gets treated as unsigned. Fix by replacing the unsigned 'immediate.bytes' (plus a cast) with the signed 'immediate.value' when assigning to the relative jump offset.

Patch 4 makes sure subflows are correctly cleaned after the end of a connection.

2023-02-08selftests: mptcp: stop tests earlierMatthieu Baerts
These 'endpoint' tests from 'mptcp_join.sh' selftest start a transfer in the background and check the status during this transfer. Once the expected events have been recorded, there is no reason to wait for the data transfer to finish. It can be stopped earlier to reduce the execution time by more than half. For these tests, the exchanged data were not verified. Errors, if any, were ignored but that's fine, plenty of other tests are looking at that. It is then OK to mute stderr now that we are sure errors will be printed (and still ignored) because the transfer is stopped before the end.

2023-02-08mptcp: be careful on subflow status propagation on errorsPaolo Abeni
Currently the subflow error report callback unconditionally propagates the fallback subflow status to the owning msk. If the msk is already orphaned, the above prevents the code from correctly tracking the msk moving to the TCP_CLOSE state and doing the appropriate cleanup. All the above causes increasing memory usage over time and sporadic self-tests failures. There is a great deal of infrastructure trying to propagate correctly the fallback subflow status to the owning mptcp socket, e.g. via mptcp_subflow_eof() and subflow_sched_work_if_closed(): in the error propagation path we need only to cope with unorphaned sockets.

2023-02-08mptcp: fix locking for in-kernel listener creationPaolo Abeni
For consistency, in mptcp_pm_nl_create_listen_socket(), we need to call the __mptcp_nmpc_socket() under the msk socket lock. Note that as a side effect, mptcp_subflow_create_socket() needs a 'nested' lockdep annotation, as it will acquire the subflow (kernel) socket lock under the in-kernel listener msk socket lock. The current lack of locking is almost harmless, because the relevant socket is not exposed to the user space, but in future we will add more complexity to the mentioned helper, let's play safe.

2023-02-08mptcp: do not wait for bare sockets' timeoutPaolo Abeni
If the peer closes all the existing subflows for a given mptcp socket and later the application closes it, the current implementation let it survive until the timewait timeout expires. While the above is allowed by the protocol specification it consumes resources for almost no reason and additionally causes sporadic self-tests failures. Let's move the mptcp socket to the TCP_CLOSE state when there are no alive subflows at close time, so that the allocated resources will be freed immediately.

2023-02-08net: ethernet: mtk_eth_soc: fix DSA TX tag hwaccel for switch port 0Vladimir Oltean
Arınç reports that on his MT7621AT Unielec U7621-06 board and MT7623NI Bananapi BPI-R2, packets received by the CPU over mt7530 switch port 0 (of which this driver acts as the DSA master) are not processed correctly by software. More precisely, they arrive without a DSA tag (in packet or in the hwaccel area - skb_metadata_dst()), so DSA cannot demux them towards the switch's interface for port 0. Traffic from other ports receives a skb_metadata_dst() with the correct port and is demuxed properly. Looking at mtk_poll_rx(), it becomes apparent that this driver uses the skb vlan hwaccel area: union { u32 vlan_all; struct { __be16 vlan_proto; __u16 vlan_tci; }; }; as a temporary storage for the VLAN hwaccel tag, or the DSA hwaccel tag. If this is a DSA master it's a DSA hwaccel tag, and finally clears up the skb VLAN hwaccel header. I'm guessing that the problem is the (mis)use of API. skb_vlan_tag_present() looks like this: #define skb_vlan_tag_present(__skb) (!!(__skb)->vlan_all) So if both vlan_proto and vlan_tci are zeroes, skb_vlan_tag_present() returns precisely false. I don't know for sure what is the format of the DSA hwaccel tag, but I surely know that lowermost 3 bits of vlan_proto are 0 when receiving from port 0: unsigned int port = vlan_proto & GENMASK(2, 0); If the RX descriptor has no other bits set to non-zero values in RX_DMA_VTAG, then the call to __vlan_hwaccel_put_tag() will not, in fact, make the subsequent skb_vlan_tag_present() return true, because it's implemented like this: static inline void __vlan_hwaccel_put_tag(struct sk_buff *skb, __be16 vlan_proto, u16 vlan_tci) { skb->vlan_proto = vlan_proto; skb->vlan_tci = vlan_tci; } What we need to do to fix this problem (assuming this is the problem) is to stop using skb->vlan_all as temporary storage for driver affairs, and just create some local variables that serve the same purpose, but hopefully better. Instead of calling skb_vlan_tag_present(), let's look at a boolean has_hwaccel_tag which we set to true when the RX DMA descriptors have something. Disambiguate based on netdev_uses_dsa() whether this is a VLAN or DSA hwaccel tag, and only call __vlan_hwaccel_put_tag() if we're certain it's a VLAN tag. Arınç confirms that the treatment works, so this validates the assumption.

Now that the key associated with the "test_dummy_operation" mount option is added on-demand when it's needed, rather than immediately when the filesystem is mounted, fscrypt_destroy_keyring() no longer needs to be called from __put_super() to avoid a memory leak on mount failure.

2023-02-07fscrypt: add the test dummy encryption key on-demandEric Biggers
When the key for an inode is not found but the inode is using the test_dummy_encryption policy, automatically add the test_dummy_encryption key to the filesystem keyring. This eliminates the need for all the individual filesystems to do this at mount time, which is a bit tricky to clean up from on failure. Note: this covers the call to fscrypt_find_master_key() from inode key setup, but not from the fscrypt ioctls. So, this isn't *exactly* the same as the key being present from the very beginning. I think we can tolerate that, though, since the inode key setup caller is the only one that actually matters in the context of test_dummy_encryption.

2023-02-07igc: Add ndo_tx_timeout supportSasha Neftin
On some platforms, 100/1000/2500 speeds seem to have sometimes problems reporting false positive tx unit hang during stressful UDP traffic. Likely other Intel drivers introduce responses to a tx hang. Update the 'tx hang' comparator with the comparison of the head and tail of ring pointers and restore the tx_timeout_factor to the previous value (one). This can be test by using netperf or iperf3 applications. Example: iperf3 -s -p 5001 iperf3 -c 192.168.0.2 --udp -p 5001 --time 600 -b 0 netserver -p 16604 netperf -H 192.168.0.2 -l 600 -p 16604 -t UDP_STREAM -- -m 64000 Fixes: b27b8dc77b5e ("igc: Increase timeout value for Speed 100/1000/2500") Signed-off-by: Sasha Neftin <sasha.neftin@intel.com> Tested-by: Naama Meir <naamax.meir@linux.intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com> Link: https://lore.kernel.org/r/20230206235818.662384-1-anthony.l.nguyen@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-02-07net: mana: Fix accessing freed irq affinity_hintHaiyang Zhang
After calling irq_set_affinity_and_hint(), the cpumask pointer is saved in desc->affinity_hint, and will be used later when reading /proc/irq/<num>/affinity_hint. So the cpumask variable needs to be persistent. Otherwise, we are accessing freed memory when reading the affinity_hint file. Also, need to clear affinity_hint before free_irq(), otherwise there is a one-time warning and stack trace during module unloading: [ 243.948687] WARNING: CPU: 10 PID: 1589 at kernel/irq/manage.c:1913 free_irq+0x318/0x360 ...
