commit 65870fa7 upstream. Until interface is up [and assuming ringparams weren't explicitly configured] when queried for the size of its rings bnx2x would claim they're the maximal size by default. That is incorrect as by default the maximal number of buffers would be equally divided between the various rx rings. This prevents the user from actually setting the number of elements on each rx ring to be of maximal size prior to transitioning the interface into up state. To fix this, make a rough estimation about the number of buffers. It wouldn't always be accurate, but it would be much better than current estimation and would allow users to increase number of buffers during early initialization of the interface. Reported-by:

commit f209fa03 upstream. During a PCI error recovery, like the ones provoked by EEH in the ppc64 platform, all IO to the device must be blocked while the recovery is completed. Current 8250_pci implementation only suspends the port instead of detaching it, which doesn't prevent incoming accesses like TIOCMGET and TIOCMSET calls from reaching the device. Those end up racing with the EEH recovery, crashing it. Similar races were also observed when opening the device and when shutting it down during recovery. This patch implements a more robust IO blockage for the 8250_pci recovery by unregistering the port at the beginning of the procedure and re-adding it afterwards. Since the port is detached from the uart layer, we can be sure that no request will make through to the device during recovery. This is similar to the solution used by the JSM serial driver. I thank Peter Hurley <peter@hurleysoftware.com> for valuable input on this one over one year ago. Signed-off-by:

commit f3951a37 upstream. In sg_common_write(), we free the block request and return -ENODEV if the device is detached in the middle of the SG_IO ioctl(). Unfortunately, sg_finish_rem_req() also tries to free srp->rq, so we end up freeing rq->cmd in the already free rq object, and then free the object itself out from under the current user. This ends up corrupting random memory via the list_head on the rq object. The most common crash trace I saw is this: ------------[ cut here ]------------ kernel BUG at block/blk-core.c:1420! Call Trace: [<ffffffff81281eab>] blk_put_request+0x5b/0x80 [<ffffffffa0069e5b>] sg_finish_rem_req+0x6b/0x120 [sg] [<ffffffffa006bcb9>] sg_common_write.isra.14+0x459/0x5a0 [sg] [<ffffffff8125b328>] ? selinux_file_alloc_security+0x48/0x70 [<ffffffffa006bf95>] sg_new_write.isra.17+0x195/0x2d0 [sg] [<ffffffffa006cef4>] sg_ioctl+0x644/0xdb0 [sg] [<ffffffff81170f80>] do_vfs_ioctl+0x90/0x520 [<ffffffff81258967>] ? file_has_perm+0x97/0xb0 [<ffffffff811714a1>] SyS_ioctl+0x91/0xb0 [<ffffffff81602afb>] tracesys+0xdd/0xe2 RIP [<ffffffff81281e04>] __blk_put_request+0x154/0x1a0 The solution is straightforward: just set srp->rq to NULL in the failure branch so that sg_finish_rem_req() doesn't attempt to re-free it. Additionally, since sg_rq_end_io() will never be called on the object when this happens, we need to free memory backing ->cmd if it isn't embedded in the object itself. KASAN was extremely helpful in finding the root cause of this bug. Signed-off-by:

commit d667f785 upstream. We received two reports of BUG_ON in bnad_txcmpl_process() where hw_consumer_index appeared to be ahead of producer_index. Out of order write/read of these variables could explain these reports. bnad_start_xmit(), as a producer of tx descriptors, has a few memory barriers sprinkled around writes to producer_index and the device's doorbell but they're not paired with anything in bnad_txcmpl_process(), a consumer. Since we are synchronizing with a device, we must use mandatory barriers, not smp_*. Also, I didn't see the purpose of the last smp_mb() in bnad_start_xmit(). Signed-off-by:

commit 05692d70 upstream. The VFIO_DEVICE_SET_IRQS ioctl did not sufficiently sanitize user-supplied integers, potentially allowing memory corruption. This patch adds appropriate integer overflow checks, checks the range bounds for VFIO_IRQ_SET_DATA_NONE, and also verifies that only single element in the VFIO_IRQ_SET_DATA_TYPE_MASK bitmask is set. VFIO_IRQ_SET_ACTION_TYPE_MASK is already correctly checked later in vfio_pci_set_irqs_ioctl(). Furthermore, a kzalloc is changed to a kcalloc because the use of a kzalloc with an integer multiplication allowed an integer overflow condition to be reached without this patch. kcalloc checks for overflow and should prevent a similar occurrence.

commit 43849785 upstream. Read access to the SPI flash are broken on da850-evm, i.e. the data read is not what is actually programmed on the flash. According to the datasheet for the M25P64 part present on the da850-evm, if the SPI frequency is higher than 20MHz then the READ command is not usable anymore and only the FAST_READ command can be used to read data. This commit specifies in the DTS that we should use FAST_READ command instead of the READ command. Tested-by:

commit ddc37832 upstream. On APQ8060, the kernel crashes in arch_hw_breakpoint_init, taking an undefined instruction trap within write_wb_reg. This is because Scorpion CPUs erroneously appear to set DBGPRSR.SPD when WFI is issued, even if the core is not powered down. When DBGPRSR.SPD is set, breakpoint and watchpoint registers are treated as undefined. It's possible to trigger similar crashes later on from userspace, by requesting the kernel to install a breakpoint or watchpoint, as we can go idle at any point between the reset of the debug registers and their later use. This has always been the case. Given that this has always been broken, no-one has complained until now, and there is no clear workaround, disable hardware breakpoints and watchpoints on Scorpion to avoid these issues.

commit 89e9f7bc upstream.

Work around this by ignoring _CRS on this system. The downside is that we may not assign resources correctly to hot-added PCI devices (if they are possible on this system).

commit 5d7400c4 upstream. Always stating PIN_CONFIG_BIAS_DISABLE is supported gives untrue output when examining /sys/kernel/debug/pinctrl/e6060000.pfc/pinconf-pins if the operation get_bias() is implemented but the pin is not handled by the get_bias() implementation. In that case the output will state that "input bias disabled" indicating that this pin has bias control support. Make support for PIN_CONFIG_BIAS_DISABLE depend on that the pin either supports SH_PFC_PIN_CFG_PULL_UP or SH_PFC_PIN_CFG_PULL_DOWN. This also solves the issue where SoC specific implementations print error messages if their particular implementation of {set,get}_bias() is called with a pin it does not know about. Signed-off-by:

commit 802c0388 upstream. The sysrq input handler should be attached to the input device which has a left alt key. On 32-bit kernels, some input devices which has a left alt key cannot attach sysrq handler. Because the keybit bitmap in struct input_device_id for sysrq is not correctly initialized. KEY_LEFTALT is 56 which is greater than BITS_PER_LONG on 32-bit kernels. I found this problem when using a matrix keypad device which defines a KEY_LEFTALT (56) but doesn't have a KEY_O (24 == 56%32). Cc: Jiri Slaby <jslaby@suse.com> Signed-off-by:

commit 259b77ef upstream. The TCA8418 might be used using different interrupt triggers on various boards. This is not working so far because the current code forces a falling edge trigger. The device tree already provides a trigger type, so let's use whatever it sets up, and since we can be loaded without DT, keep the old behaviour for the non-DT case. Signed-off-by:

commit 45536d37 upstream. Postpone axis initialization to the first open instead of doing it in joydev_connect. This is to make sure the generated startup events are representative of the current joystick state rather than what it was when joydev_connect() was called, potentially much earlier. Once the first user is connected to joydev node we'll be updating joydev->abs[] values and subsequent clients will be getting correct initial states as well. This solves issues with joystick driven menus that start scrolling up each time they are started, until the user moves the joystick to generate events. In emulator menu setups where the menu program is restarted every time the game exits, the repeated need to move the joystick to stop the unintended scrolling gets old rather quickly...
