[ Upstream commit 20eee6e5 ] The `connected` value for wired devices was not properly initialized, it must be set to `true` upon creation, because wired devices do not generate connection events. When a raw client (the Steam Client) uses the device, the input device is destroyed. Then, when the raw client finishes, it must be recreated. But since the `connected` variable was false this never happended. Signed-off-by:

[ Upstream commit f11421ba ] Atomic operations that span cache lines are super-expensive on x86 (not just to the current processor, but also to other processes as all memory operations are blocked until the operation completes). Upcoming x86 processors have a switch to cause such operations to generate a #AC trap. It is expected that some real time systems will enable this mode in BIOS. In preparation for this, it is necessary to fix code that may execute atomic instructions with operands that cross cachelines because the #AC trap will crash the kernel. Since "pwol_mask" is local and never exposed to concurrency, there is no need to set bits in pwol_mask using atomic operations. Directly operate on the byte which contains the bit instead of using __set_bit() to avoid any big endian concern due to type cast to unsigned long in __set_bit(). Suggested-by:

[ Upstream commit 19b61392 ] dw_spi_irq() and dw_spi_transfer_one concurrent calls. I find a panic in dw_writer(): txw = *(u8 *)(dws->tx), when dw->tx==null, dw->len==4, and dw->tx_end==1. When tpm driver's message overtime dw_spi_irq() and dw_spi_transfer_one may concurrent visit dw_spi, so I think dw_spi structure lack of protection. Otherwise dw_spi_transfer_one set dw rx/tx buffer and then open irq, store dw rx/tx instructions and other cores handle irq load dw rx/tx instructions may out of order. [ 1025.321302] Call trace: ...

[ Upstream commit 63078b6b ] The micro-USB connector on Motorola Mapphone devices can be muxed between the SoC and the mdm6600 modem. But even when used for the SoC, configuring the PHY with ID pin grounded will wake up the modem from idle state. Looks like the issue is probably caused by line glitches. We can prevent the glitches by using a previously unknown mode of the GPIO mux to prevent the USB lines from being connected to the moden while configuring the USB PHY, and enable the USB lines after configuring the PHY. Note that this only prevents waking up mdm6600 as regular USB A-host mode, and does not help when connected to a lapdock. The lapdock specific issue still needs to be debugged separately.

[ Upstream commit 2e24cd75 ] The current implementations of ops->bind_class() are merely searching for classid and updating class in the struct tcf_result, without invoking either of cl_ops->bind_tcf() or cl_ops->unbind_tcf(). This breaks the design of them as qdisc's like cbq use them to count filters too. This is why syzbot triggered the warning in cbq_destroy_class(). In order to fix this, we have to call cl_ops->bind_tcf() and cl_ops->unbind_tcf() like the filter binding path. This patch does so by refactoring out two helper functions __tcf_bind_filter() and __tcf_unbind_filter(), which are lockless and accept a Qdisc pointer, then teaching each implementation to call them correctly. Note, we merely pass the Qdisc pointer as an opaque pointer to each filter, they only need to pass it down to the helper functions without understanding it at all.

commit bd56cea0 upstream. The chelsio crypto driver is casting 'struct crypto_aead' directly to 'struct crypto_tfm', which is incorrect because the crypto_tfm isn't the first field of 'struct crypto_aead'. Consequently, the calls to crypto_tfm_set_flags() are modifying some other field in the struct. Also, the driver is setting CRYPTO_TFM_RES_BAD_KEY_LEN in ->setauthsize(), not just in ->setkey(). This is incorrect since this flag is for bad key lengths, not for bad authentication tag lengths. Fix these bugs by removing the broken crypto_tfm_set_flags() calls from ->setauthsize() and by fixing them in ->setkey().

commit dc76697d upstream. Unbinding the bcm2835aux UART driver raises the following error if the maximum number of 8250 UARTs is set to 1 (via the 8250.nr_uarts module parameter or CONFIG_SERIAL_8250_RUNTIME_UARTS): (NULL device *): Removing wrong port: a6f80333 != fa20408b That's because bcm2835aux_serial_probe() retrieves UART line number 1 from the devicetree and stores it in data->uart.port.line, while serial8250_register_8250_port() instead uses UART line number 0, which is stored in data->line. On driver unbind, bcm2835aux_serial_remove() uses data->uart.port.line, which contains the wrong number. Fix it. The issue does not occur if the maximum number of 8250 UARTs is >= 2.

commit d579c43c upstream. It appears that the drivers does not go into power save correctly the NULL data packets are not being transmitted because it not enabled in mac80211. The driver needs to capture ieee80211_is_nullfunc headers and copy the duration_id to it's own duration data header. Cc: stable <stable@vger.kernel.org> Signed-off-by:

commit d971fdd3 upstream. It appears that the driver still transmits in CTS protect mode even though it is not enabled in mac80211. That is both packet types PK_TYPE_11GA and PK_TYPE_11GB both use CTS protect. The only difference between them GA does not use B rates. Find if only B rate in GB or GA in protect mode otherwise transmit packets as PK_TYPE_11A. Cc: stable <stable@vger.kernel.org> Signed-off-by:

commit 4cc41cbc upstream. Currently when the call to prism2sta_ifst fails a netdev_err error is reported, error return variable result is set to -1 but the function always returns 0 for success.

commit 4d1356ac upstream. If the length of the socket buffer is 0xFFFFFFFF (max size for an unsigned int), then payload_len becomes 0xFFFFFFF1 after subtracting 14 (ETH_HLEN). Then, mdp_len is set to payload_len + 16 (MDP_HDR_LEN) which overflows and results in a value of 2. These values for payload_len and mdp_len will pass current buffer size checks. This patch checks if derived from skb->len sum may overflow. The check is based on the following idea: For any `unsigned V1, V2` and derived `unsigned SUM = V1 + V2`, `V1 + V2` overflows iif `SUM < V1`. Reported-by:

commit 38c0d5bd upstream. Commit f4a4cbb2 ("USB: ir-usb: reimplement using generic framework") switched to using the generic write implementation which may combine multiple write requests into larger transfers. This can break the IrLAP protocol where end-of-frame is determined using the USB short packet mechanism, for example, if multiple frames are sent in rapid succession.

commit 17a0184c upstream. Commit e0d795e4 ("usb: irda: cleanup on ir-usb module") added a USB IrDA header with common defines, but mistakingly switched to using the class-descriptor baud-rate bitmask values for the outbound header. This broke link-speed handling for rates above 9600 baud, but a device would also be able to operate at the default 9600 baud until a link-speed request was issued (e.g. using the TCGETS ioctl).
