[ Upstream commit 77df710b ] The Saitek X52 family of joysticks has a pair of axes that were originally (by the Windows driver) used as mouse pointer controls. The corresponding usage page is the Game Controls page, which is not recognized by the generic HID driver, and therefore, both axes get mapped to ABS_MISC. The quirk makes the second axis get mapped to ABS_MISC+1, and therefore made available separately. One Saitek X52 device is already fixed. This patch fixes the other two known devices with VID/PID 06a3:0255 and 06a3:0762. Signed-off-by:

[ Upstream commit 5110f402 ] In the timeout handler we may need to complete a request because the request that timed out may be an I/O that is a part of a serial sequence of controller teardown or initialization. In order to complete the request, we need to fence any other context that may compete with us and complete the request that is timing out. In this case, we could have a potential double completion in case a hard-irq or a different competing context triggered error recovery and is running inflight request cancellation concurrently with the timeout handler. Protect using a ctrl teardown_lock to serialize contexts that may complete a cancelled request due to error recovery or a reset. Reviewed-by:

[ Upstream commit 89d29997 ] eznps driver is supposed to be platform independent however it ends up including stuff from inside arch/arc headers leading to rand config build errors. The quick hack to fix this (proper fix is too much chrun for non active user-base) is to add following to nps platform agnostic header. - copy AUX_IENABLE from arch/arc header - move CTOP_AUX_IACK from arch/arc/plat-eznps/*/** Reported-by:

[ Upstream commit 91244d10 ] Set the skb's network_header before it is passed to the underlying Ethernet device for transmission. This patch fixes the following issue: When we use this driver with AF_PACKET sockets, there would be error messages of: protocol 0805 is buggy, dev (Ethernet interface name) printed in the system "dmesg" log. This is because skbs passed down to the Ethernet device for transmission don't have their network_header properly set, and the dev_queue_xmit_nit function in net/core/dev.c complains about this. Reason of setting the network_header to this place (at the end of the Ethernet header, and at the beginning of the Ethernet payload): Because when this driver receives an skb from the Ethernet device, the network_header is also set at this place.

[ Upstream commit cc5453a5 ] If an sctp connection gets re-used, heartbeats are flagged as invalid because their vtag doesn't match. Handle this in a similar way as TCP conntrack when it suspects that the endpoints and conntrack are out-of-sync. When a HEARTBEAT request fails its vtag validation, flag this in the conntrack state and accept the packet. When a HEARTBEAT_ACK is received with an invalid vtag in the reverse direction after we allowed such a HEARTBEAT through, assume we are out-of-sync and re-set the vtag info. v2: remove left-over snippet from an older incarnation that moved new_state/old_state assignments, thats not needed so keep that as-is.

[ Upstream commit 9d5dcefb ] As the comments in this patch say, if we tune and find all phases are valid it's _almost_ as bad as no phases being found valid. Probably all phases are not really reliable but we didn't detect where the unreliable place is. That means we'll essentially be guessing and hoping we get a good phase. This is not just a problem in theory. It was causing real problems on a real board. On that board, most often phase 10 is found as the only invalid phase, though sometimes 10 and 11 are invalid and sometimes just 11. Some percentage of the time, however, all phases are found to be valid. When this happens, the current logic will decide to use phase 11. Since phase 11 is sometimes found to be invalid, this is a bad choice. Sure enough, when phase 11 is picked we often get mmc errors later in boot. I have seen cases where all phases were found to be valid 3 times in a row, so increase the retry count to 10 just to be extra sure.

[ Upstream commit 53de092f ] It was discovered that sdparm will fail when attempting to disable write cache on a SATA disk connected via libsas. In the ATA command set the write cache state is controlled through the SET FEATURES operation. This is roughly corresponds to MODE SELECT in SCSI and the latter command is what is used in the SCSI-ATA translation layer. A subtle difference is that a MODE SELECT carries data whereas SET FEATURES is defined as a non-data command in ATA. Set the DMA data direction to DMA_NONE if the requested ATA command is identified as non-data.

However, the same is not done for fresh napi instances in netif_napi_add(), even though we expect NAPI instances to be added as disabled. This causes crashes during driver reconfiguration (enabling XDP, changing the channel count) - if there is any printk() after netif_napi_add() but before napi_enable().

[ Upstream commit 2a63866c ] syzbot is reporting hung task at nbd_ioctl() [1], for there are two problems regarding TIPC's connectionless socket's shutdown() operation. ---------- #include <fcntl.h> #include <sys/socket.h> #include <sys/ioctl.h> #include <linux/nbd.h> #include <unistd.h> int main(int argc, char *argv[]) { const int fd = open("/dev/nbd0", 3); alarm(5); ioctl(fd, NBD_SET_SOCK, socket(PF_TIPC, SOCK_DGRAM, 0)); ioctl(fd, NBD_DO_IT, 0); /* To be interrupted by SIGALRM. */ return 0; } ---------- One problem is that wait_for_completion() from flush_workqueue() from nbd_start_device_ioctl() from nbd_ioctl() cannot be completed when nbd_start_device_ioctl() received a signal at wait_event_interruptible(), for tipc_shutdown() from kernel_sock_shutdown(SHUT_RDWR) from nbd_mark_nsock_dead() from sock_shutdown() from nbd_start_device_ioctl() is failing to wake up a WQ thread sleeping at wait_woken() from tipc_wait_for_rcvmsg() from sock_recvmsg() from sock_xmit() from nbd_read_stat() from recv_work() scheduled by nbd_start_device() from nbd_start_device_ioctl(). Fix this problem by always invoking sk->sk_state_change() (like inet_shutdown() does) when tipc_shutdown() is called. The other problem is that tipc_wait_for_rcvmsg() cannot return when tipc_shutdown() is called, for tipc_shutdown() sets sk->sk_shutdown to SEND_SHUTDOWN (despite "how" is SHUT_RDWR) while tipc_wait_for_rcvmsg() needs sk->sk_shutdown set to RCV_SHUTDOWN or SHUTDOWN_MASK. Fix this problem by setting sk->sk_shutdown to SHUTDOWN_MASK (like inet_shutdown() does) when the socket is connectionless.

[ Upstream commit d3b990b7 ] This patch fixes two main problems seen when removing NetLabel mappings: memory leaks and potentially extra audit noise. The memory leaks are caused by not properly free'ing the mapping's address selector struct when free'ing the entire entry as well as not properly cleaning up a temporary mapping entry when adding new address selectors to an existing entry. This patch fixes both these problems such that kmemleak reports no NetLabel associated leaks after running the SELinux test suite. The potentially extra audit noise was caused by the auditing code in netlbl_domhsh_remove_entry() being called regardless of the entry's validity. If another thread had already marked the entry as invalid, but not removed/free'd it from the list of mappings, then it was possible that an additional mapping removal audit record would be generated. This patch fixes this by returning early from the removal function when the entry was previously marked invalid. This change also had the side benefit of improving the code by decreasing the indentation level of large chunk of code by one (accounting for most of the diffstat).

Tascam FE-8 is known to support communication by asynchronous transaction only. The support can be implemented in userspace application and snd-firewire-ctl-services project has the support. However, ALSA firewire-tascam driver is bound to the model. This commit changes device entries so that the model is excluded. In a commit 53b3ffee ("ALSA: firewire-tascam: change device probing processing"), I addressed to the concern that version field in configuration differs depending on installed firmware. However, as long as I checked, the version number is fixed. It's safe to return version number back to modalias.
