2023-04-13net: enetc: workaround for unresponsive pMAC after receiving express trafficVladimir Oltean
I have observed an issue where the RX direction of the LS1028A ENETC pMAC seems unresponsive. The minimal procedure to reproduce the issue is: 1. Connect ENETC port 0 with a loopback RJ45 cable to one of the Felix switch ports (0). 2. Bring the ports up (MAC Merge layer is not enabled on either end). 3. Send a large quantity of unidirectional (express) traffic from Felix to ENETC. I tried altering frame size and frame count, and it doesn't appear to be specific to either of them, but rather, to the quantity of octets received. Lowering the frame count, the minimum quantity of packets to reproduce relatively consistently seems to be around 37000 frames at 1514 octets (w/o FCS) each. 4. Using ethtool --set-mm, enable the pMAC in the Felix and in the ENETC ports, in both RX and TX directions, and with verification on both ends. 5. Wait for verification to complete on both sides. 6. Configure a traffic class as preemptible on both ends. 7. Send some packets again. The issue is at step 5, where the verification process of ENETC ends (meaning that Felix responds with an SMD-R and ENETC sees the response), but the verification process of Felix never ends (it remains VERIFYING). If step 3 is skipped or if ENETC receives less traffic than approximately that threshold, the test runs all the way through (verification succeeds on both ends, preemptible traffic passes fine). If, between step 4 and 5, the step below is also introduced: 4.1. Disable and re-enable PM0_COMMAND_CONFIG bit RX_EN then again, the sequence of steps runs all the way through, and verification succeeds, even if there was the previous RX traffic injected into ENETC. Traffic sent *by* the ENETC port prior to enabling the MAC Merge layer does not seem to influence the verification result, only received traffic does. The LS1028A manual does not mention any relationship between PM0_COMMAND_CONFIG and MMCSR, and the hardware people don't seem to know for now either. The bit that is toggled to work around the issue is also toggled by enetc_mac_enable(), called from phylink's mac_link_down() and mac_link_up() methods - which is how the workaround was found: verification would work after a link down/up.

2023-04-13sctp: fix a potential overflow in sctp_ifwdtsn_skipXin Long
Currently, when traversing ifwdtsn skips with _sctp_walk_ifwdtsn, it only checks the pos against the end of the chunk. However, the data left for the last pos may be < sizeof(struct sctp_ifwdtsn_skip), and dereference it as struct sctp_ifwdtsn_skip may cause coverflow. This patch fixes it by checking the pos against "the end of the chunk - sizeof(struct sctp_ifwdtsn_skip)" in sctp_ifwdtsn_skip, similar to sctp_fwdtsn_skip.

2023-04-12rtnetlink: Restore RTM_NEW/DELLINK notification behaviorMartin Willi
The commits referenced below allows userspace to use the NLM_F_ECHO flag for RTM_NEW/DELLINK operations to receive unicast notifications for the affected link. Prior to these changes, applications may have relied on multicast notifications to learn the same information without specifying the NLM_F_ECHO flag. For such applications, the mentioned commits changed the behavior for requests not using NLM_F_ECHO. Multicast notifications are still received, but now use the portid of the requester and the sequence number of the request instead of zero values used previously. For the application, this message may be unexpected and likely handled as a response to the NLM_F_ACKed request, especially if it uses the same socket to handle requests and notifications. To fix existing applications relying on the old notification behavior, set the portid and sequence number in the notification only if the request included the NLM_F_ECHO flag. This restores the old behavior for applications not using it, but allows unicasted notifications for others.

2023-04-12smc: Fix use-after-free in tcp_write_timer_handler().Kuniyuki Iwashima
With Eric's ref tracker, syzbot finally found a repro for use-after-free in tcp_write_timer_handler() by kernel TCP sockets. [0] If SMC creates a kernel socket in __smc_create(), the kernel socket is supposed to be freed in smc_clcsock_release() by calling sock_release() when we close() the parent SMC socket. However, at the end of smc_clcsock_release(), the kernel socket's sk_state might not be TCP_CLOSE. This means that we have not called inet_csk_destroy_sock() in __tcp_close() and have not stopped the TCP timers. The kernel socket's TCP timers can be fired later, so we need to hold a refcnt for net as we do for MPTCP subflows in mptcp_subflow_create_socket().

2023-04-11treewide: Fix probing of devices in DT overlaysGeert Uytterhoeven
When loading a DT overlay that creates a device, the device is not probed, unless the DT overlay is unloaded and reloaded again. After the recent refactoring to improve fw_devlink, it no longer depends on the "compatible" property to identify which device tree nodes will become struct devices. fw_devlink now picks up dangling consumers (consumers pointing to descendent device tree nodes of a device that aren't converted to child devices) when a device is successfully bound to a driver. See __fw_devlink_pickup_dangling_consumers(). However, during DT overlay, a device's device tree node can have sub-nodes added/removed without unbinding/rebinding the driver. This difference in behavior between the normal device instantiation and probing flow vs. the DT overlay flow has a bunch of implications that are pointed out elsewhere[1]. One of them is that the fw_devlink logic to pick up dangling consumers is never exercised. This patch solves the fw_devlink issue by marking all DT nodes added by DT overlays with FWNODE_FLAG_NOT_DEVICE (fwnode that won't become device), and by clearing the flag when a struct device is actually created for the DT node. This way, fw_devlink knows not to have consumers waiting on these newly added DT nodes, and to propagate the dependency to an ancestor DT node that has the corresponding struct device. Based on a patch by Saravana Kannan, which covered only platform and spi devices.

2023-04-11fbmem: Reject FB_ACTIVATE_KD_TEXT from userspaceDaniel Vetter
This is an oversight from dc5bdb68b5b3 ("drm/fb-helper: Fix vt restore") - I failed to realize that nasty userspace could set this. It's not pretty to mix up kernel-internal and userspace uapi flags like this, but since the entire fb_var_screeninfo structure is uapi we'd need to either add a new parameter to the ->fb_set_par callback and fb_set_par() function, which has a _lot_ of users. Or some other fairly ugly side-channel int fb_info. Neither is a pretty prospect. Instead just correct the issue at hand by filtering out this kernel-internal flag in the ioctl handling code.

Testing is of course being upgraded, and the upgraded tests detect this situation very quickly.

There is a potential race condition in hidp_session_thread that may lead to use-after-free. For instance, the timer is active while hidp_del_timer is called in hidp_session_thread(). After hidp_session_put, then 'session' will be freed, causing kernel panic when hidp_idle_timeout is running. The solution is to use del_timer_sync instead of del_timer.
