2021-10-17can: m_can: fix iomap_read_fifo() and iomap_write_fifo()Aswath Govindraju1-2/+12
The read and writes from the fifo are from a buffer, with various fields and data at predefined offsets. So, they should not be done to the same address(or port) in case of val_count greater than 1. Therefore, fix this by using iowrite32()/ioread32() instead of ioread32_rep()/iowrite32_rep(). Also, the write into FIFO must be performed with an offset from the message ram base address. Therefore, fix the base address to mram_base.

2021-10-17block, bfq: reset last_bfqq_created on group changePaolo Valente1-0/+6
Since commit 430a67f9d616 ("block, bfq: merge bursts of newly-created queues"), BFQ maintains a per-group pointer to the last bfq_queue created. If such a queue, say bfqq, happens to move to a different group, then bfqq is no more a valid last bfq_queue created for its previous group. That pointer must then be cleared. Not resetting such a pointer may also cause UAF, if bfqq happens to also be freed after being moved to a different group. This commit performs this missing reset. As such it fixes commit 430a67f9d616 ("block, bfq: merge bursts of newly-created queues"). Such a missing reset is most likely the cause of the crash reported in [1]. With some analysis, we found that this crash was due to the above UAF. And such UAF did go away with this commit applied [1]. Anyway, before this commit, that crash happened to be triggered in conjunction with commit 2d52c58b9c9b ("block, bfq: honor already-setup queue merges"). The latter was then reverted by commit ebc69e897e17 ("Revert "block, bfq: honor already-setup queue merges""). Yet commit 2d52c58b9c9b ("block, bfq: honor already-setup queue merges") contains no error related with the above UAF, and can then be restored.

2021-10-17can: isotp: isotp_sendmsg(): fix TX buffer concurrent access in isotp_sendmsg()Ziyang Xuan1-15/+31
When isotp_sendmsg() concurrent, tx.state of all TX processes can be ISOTP_IDLE. The conditions so->tx.state != ISOTP_IDLE and wq_has_sleeper(&so->wait) can not protect TX buffer from being accessed by multiple TX processes. We can use cmpxchg() to try to modify tx.state to ISOTP_SENDING firstly. If the modification of the previous process succeed, the later process must wait tx.state to ISOTP_IDLE firstly. Thus, we can ensure TX buffer is accessed by only one process at the same time. And we should also restore the original tx.state at the subsequent error processes.

2021-10-16net: bridge: mcast: use multicast_membership_interval for IGMPv3Nikolay Aleksandrov1-3/+1
When I added IGMPv3 support I decided to follow the RFC for computing the GMI dynamically: " 8.4. Group Membership Interval The Group Membership Interval is the amount of time that must pass before a multicast router decides there are no more members of a group or a particular source on a network. This value MUST be ((the Robustness Variable) times (the Query Interval)) plus (one Query Response Interval)." But that actually is inconsistent with how the bridge used to compute it for IGMPv2, where it was user-configurable that has a correct default value but it is up to user-space to maintain it. This would make it consistent with the other timer values which are also maintained correct by the user instead of being dynamically computed. It also changes back to the previous user-expected GMI behaviour for IGMPv3 queries which were supported before IGMPv3 was added. Note that to properly compute it dynamically we would need to add support for "Robustness Variable" which is currently missing.

Since the following fix for the PHY driver this is not the case anymore: commit 7b005a1742be ("net: phy: mscc: configure both RX and TX internal delays for RGMII") In order to enable the delay we need to set the connection type to "rgmii-rxid".

The MCP2515 can be used with an SPI clock of up to 10 MHz. Set the limit accordingly to prevent any performance issues caused by the really low clock speed of 100 kHz. This removes the arbitrarily low limit on the SPI frequency, that was caused by a typo in the original dts. Without this change, receiving CAN messages on the board beyond a certain bitrate will cause overrun errors (see 'ip -det -stat link show can0'). With this fix, receiving messages on the bus works without any overrun errors for bitrates up to 1 MBit.

A new warning in clang points out a few places in this driver where a bitwise OR is being used with boolean types: drivers/input/touchscreen.c:81:17: warning: use of bitwise '|' with boolean operands [-Wbitwise-instead-of-logical] data_present = touchscreen_get_prop_u32(dev, "touchscreen-min-x", ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This use of a bitwise OR is intentional, as bitwise operations do not short circuit, which allows all the calls to touchscreen_get_prop_u32() to happen so that the last parameter is initialized while coalescing the results of the calls to make a decision after they are all evaluated. To make this clearer to the compiler, use the '|=' operator to assign the result of each touchscreen_get_prop_u32() call to data_present, which keeps the meaning of the code the same but makes it obvious that every one of these calls is expected to happen.

2021-10-15Input: snvs_pwrkey - add clk handlingUwe Kleine-König1-0/+29
On i.MX7S and i.MX8M* (but not i.MX6*) the pwrkey device has an associated clock. Accessing the registers requires that this clock is enabled. Binding the driver on at least i.MX7S and i.MX8MP while not having the clock enabled results in a complete hang of the machine. (This usually only happens if snvs_pwrkey is built as a module and the rtc-snvs driver isn't already bound because at bootup the required clk is on and only gets disabled when the clk framework disables unused clks late during boot.) This completes the fix in commit 135be16d3505 ("ARM: dts: imx7s: add snvs clock to pwrkey").
