2020-01-22tty: baudrate: Synchronise baud_table[] and baud_bits[]Andy Shevchenko

2020-01-22serial: imx: fix a race condition in receive pathUwe Kleine-König
The main irq handler function starts by first masking disabled interrupts in the status register values to ensure to only handle enabled interrupts. This is important as when the RX path in the hardware is disabled reading the RX fifo results in an external abort. This checking must be done under the port lock, otherwise the following can happen: CPU1 | CPU2 | irq triggers as there are chars | in the RX fifo | | grab port lock imx_uart_int finds RRDY enabled | and calls imx_uart_rxint which | has to wait for port lock | | disable RX (e.g. because we're | using RS485 with !RX_DURING_TX) | | release port lock read from RX fifo with RX | disabled => exception | So take the port lock only once in imx_uart_int() instead of in the functions called from there.

2020-01-22serial: 8250_bcm2835aux: Use generic remapping codeLukas Wunner
On probe the bcm2835aux UART driver misreports the register base address as 0x0: ttyS0 at MMIO 0x0 (irq = 53, base_baud = 50000000) is a 16550 That's because the driver remaps the registers itself.

The bcm2835aux UART driver stores a struct uart_8250_port in its private data even though it's only passed once to serial8250_register_8250_port() (which copies all relevant data) and becomes obsolete afterwards. Allocate the struct on the stack instead for simplicity and to conserve memory. The driver also initializes a spinlock in the struct which is never used. Drop that as well.

2020-01-22serial: 8250_bcm2835aux: Fix line mismatch on driver unbindLukas Wunner
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.

2020-01-22staging: axis-fifo: replace spinlock with mutexQuentin Deslandes
Following the device's documentation guidance, reading a packet from the device or writing a packet to it must be atomic. Previously, only reading device's vacancy (before writing on it) or occupancy (before reading from it) was locked. Hence, effectively reading the packet or writing the packet wasn't locked at all. However, reading a packet (and writing one, to a lesser extent) requires to read 3 different registers in a specific order, without missing one or else we should reset the device. This patch fixes the device's locking mechanism on the FIFO character device. As the device was using copy_from_user() and copy_to_user(), we need to replace spinlocks with mutexes.

2020-01-22staging: most: net: fix buffer overflowAndrey Shvetsov
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`.

2020-01-22crypto: arm/chacha - fix build failured when kernel mode NEON is disabledArd Biesheuvel
When the ARM accelerated ChaCha driver is built as part of a configuration that has kernel mode NEON disabled, we expect the compiler to propagate the build time constant expression IS_ENABLED(CONFIG_KERNEL_MODE_NEON) in a way that eliminates all the cross-object references to the actual NEON routines, which allows the chacha-neon-core.o object to be omitted from the build entirely. Unfortunately, this fails to work as expected in some cases, and we may end up with a build error such as chacha-glue.c:(.text+0xc0): undefined reference to `chacha_4block_xor_neon' caused by the fact that chacha_doneon() has not been eliminated from the object code, even though it will never be called in practice. Let's fix this by adding some IS_ENABLED(CONFIG_KERNEL_MODE_NEON) tests that are not strictly needed from a logical point of view, but should help the compiler infer that the NEON code paths are unreachable in those cases.

2020-01-22crypto: chacha20poly1305 - add back missing test vectors and test chunkingJason A. Donenfeld
When this was originally ported, the 12-byte nonce vectors were left out to keep things simple. I agree that we don't need nor want a library interface for 12-byte nonces. But these test vectors were specially crafted to look at issues in the underlying primitives and related interactions. Therefore, we actually want to keep around all of the test vectors, and simply have a helper function to test them with. Secondly, the sglist-based chunking code in the library interface is rather complicated, so this adds a developer-only test for ensuring that all the book keeping is correct, across a wide array of possibilities.

We were using the irq field of the drvdata struct in an overloaded fahsion - saving the IRQ number during init and then storing the pending itnerrupt sources during interrupt in the same field. This worked because these usage are mutually exclusive but are confusing. So simplify the code and change the init use case to use a simple local variable.
