2019-11-04can: rx-offload: can_rx_offload_offload_one(): use ERR_PTR() to propagate ↵Marc Kleine-Budde
error value in case of errors Before this patch can_rx_offload_offload_one() returns a pointer to a skb containing the read CAN frame or a NULL pointer. However the meaning of the NULL pointer is ambiguous, it can either mean the requested mailbox is empty or there was an error. This patch fixes this situation by returning: - pointer to skb on success - NULL pointer if mailbox is empty - ERR_PTR() in case of an error All users of can_rx_offload_offload_one() have been adopted, no functional change intended.

queue overflow or OOM If the rx-offload skb_queue is full or the skb allocation fails (due to OOM), the mailbox contents is discarded. This patch adds the incrementing of the rx_fifo_errors statistics counter. Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
2019-11-04can: rx-offload: can_rx_offload_offload_one(): do not increase the skb_queue ↵Marc Kleine-Budde
beyond skb_queue_len_max The skb_queue is a linked list, holding the skb to be processed in the next NAPI call. Without this patch, the queue length in can_rx_offload_offload_one() is limited to skb_queue_len_max + 1. As the skb_queue is a linked list, no array or other resources are accessed out-of-bound, however this behaviour is counterintuitive. This patch limits the rx-offload skb_queue length to skb_queue_len_max.

2019-11-04can: rx-offload: can_rx_offload_queue_tail(): fix error handling, avoid skb ↵Marc Kleine-Budde
mem leak If the rx-offload skb_queue is full can_rx_offload_queue_tail() will not queue the skb and return with an error. This patch frees the skb in case of a full queue, which brings can_rx_offload_queue_tail() in line with the can_rx_offload_queue_sorted() function, which has been adjusted in the previous patch. The return value is adjusted to -ENOBUFS to better reflect the actual problem. The device stats handling is left to the caller.

2019-11-04can: rx-offload: can_rx_offload_queue_sorted(): fix error handling, avoid ↵Marc Kleine-Budde
skb mem leak If the rx-offload skb_queue is full can_rx_offload_queue_sorted() will not queue the skb and return with an error. None of the callers of this function, issue a kfree_skb() to free the not queued skb. This results in a memory leak. This patch fixes the problem by freeing the skb in case of a full queue. The return value is adjusted to -ENOBUFS to better reflect the actual problem. The device stats handling is left to the callers, as this function might be used in both the rx and tx path.

2019-11-04can: c_can: c_can_poll(): only read status register after status IRQKurt Van Dijck
When the status register is read without the status IRQ pending, the chip may not raise the interrupt line for an upcoming status interrupt and the driver may miss a status interrupt. It is critical that the BUSOFF status interrupt is forwarded to the higher layers, since no more interrupts will follow without intervention.

2019-11-04can: peak_usb: fix a potential out-of-sync while decoding packetsStephane Grosjean
When decoding a buffer received from PCAN-USB, the first timestamp read in a packet is a 16-bit coded time base, and the next ones are an 8-bit offset to this base, regardless of the type of packet read. This patch corrects a potential loss of synchronization by using a timestamp index read from the buffer, rather than an index of received data packets, to determine on the sizeof the timestamp to be read from the packet being decoded.

2019-11-04clk: ti: clkctrl: Fix failed to enable error with double udelay timeoutTony Lindgren
Commit 3d8598fb9c5a ("clk: ti: clkctrl: use fallback udelay approach if timekeeping is suspended") added handling for cases when timekeeping is suspended. But looks like we can still get occasional "failed to enable" errors on the PM runtime resume path with udelay() returning faster than expected. With ti-sysc interconnect target module driver this leads into device failure with PM runtime failing with "failed to enable" clkctrl error. Let's fix the issue with a delay of two times the desired delay as in often done for udelay() to account for the inaccuracy.

2019-11-02HID: i2c-hid: Send power-on command after resetHans de Goede
Before commit 67b18dfb8cfc ("HID: i2c-hid: Remove runtime power management"), any i2c-hid touchscreens would typically be runtime-suspended between the driver loading and Xorg or a Wayland compositor opening it, causing it to be resumed again. This means that before this change, we would call i2c_hid_set_power(OFF), i2c_hid_set_power(ON) before the graphical session would start listening to the touchscreen. It turns out that at least some SIS touchscreens, such as the one found on the Asus T100HA, need a power-on command after reset, otherwise they will not send any events.

2019-11-01r8169: fix wrong PHY ID issue with RTL8168dpHeiner Kallweit
As reported in [0] at least one RTL8168dp version has problems establishing a link. This chip version has an integrated RTL8211b PHY, however the chip seems to report a wrong PHY ID, resulting in a wrong PHY driver (for Generic Realtek PHY) being loaded. Work around this issue by adding a hook to r8168dp_2_mdio_read() for returning the correct PHY ID.

2019-11-01net: dsa: bcm_sf2: Fix IMP setup for port different than 8Florian Fainelli
Since it became possible for the DSA core to use a CPU port different than 8, our bcm_sf2_imp_setup() function was broken because it assumes that registers are applicable to port 8. In particular, the port's MAC is going to stay disabled, so make sure we clear the RX_DIS and TX_DIS bits if we are not configured for port 8.

2019-11-01inet: stop leaking jiffies on the wireEric Dumazet
Historically linux tried to stick to RFC 791, 1122, 2003 for IPv4 ID field generation. RFC 6864 made clear that no matter how hard we try, we can not ensure unicity of IP ID within maximum lifetime for all datagrams with a given source address/destination address/protocol tuple. Linux uses a per socket inet generator (inet_id), initialized at connection startup with a XOR of 'jiffies' and other fields that appear clear on the wire. Thiemo Nagel pointed that this strategy is a privacy concern as this provides 16 bits of entropy to fingerprint devices. Let's switch to a random starting point, this is just as good as far as RFC 6864 is concerned and does not leak anything critical.
