commit 4a8588a1 upstream. If the serial port gets closed while a RX transfer is in progress, the timer might fire after the serial port shutdown finished.

commit 37480a05 upstream. Commit 26df6d13 ("tty: Add EXTPROC support for LINEMODE") allows a process which has opened a pty master to send _any_ signal to the process group of the pty slave. Although potentially exploitable by a malicious program running a setuid program on a pty slave, it's unknown if this exploit currently exists. Limit to signals actually used.

commit cd8f4384 upstream. The base address of the scheduler in the device's memory (SRAM) comes from two different sources. The periphery register and the alive notification from the firmware. We have a check in iwl_pcie_tx_start that ensures that they are the same. When we resume from WoWLAN, the firmware may have crashed for whatever reason. In that case, the whole device may be reset which means that the periphery register will hold a meaningless value. When we come to compare trans_pcie->scd_base_addr (which really holds the value we had when we loaded the WoWLAN firmware upon suspend) and the current value of the register, we don't see a match unsurprisingly. Trick the check to avoid a loud yet harmless WARN. Note that when the WoWLAN has crashed, we will see that in iwl_trans_pcie_d3_resume which will let the op_mode know. Once the op_mode is informed that the WowLAN firmware has crashed, it can't do much besides resetting the whole device. Reviewed-by:

commit 5523d11c upstream. We don't really need to use different mac colors when adding mac contexts, because they're not used anywhere. In fact, the firmware doesn't accept 255 as a valid color, so we get into a SYSASSERT 0x3401 when we reach that. Remove the color increment to use always zero and avoid reaching 255. Signed-off-by:

commit c9919790 upstream. The usb_hcd_unlink_urb() routine in hcd.c contains two possible use-after-free errors. The dev_dbg() statement at the end of the routine dereferences urb and urb->dev even though both structures may have been deallocated. This patch fixes the problem by storing urb->dev in a local variable (avoiding the dereference of urb) and moving the dev_dbg() up before the usb_put_dev() call. Signed-off-by:

commit 074f9dd5 upstream. Currently the USB stack assumes that all host controller drivers are capable of receiving wakeup requests from downstream devices. However, this isn't true for the isp1760-hcd driver, which means that it isn't safe to do a runtime suspend of any device attached to a root-hub port if the device requires wakeup. This patch adds a "cant_recv_wakeups" flag to the usb_hcd structure and sets the flag in isp1760-hcd. The core is modified to prevent a direct child of the root hub from being put into runtime suspend with wakeup enabled if the flag is set. Signed-off-by:

Fix that by finishing the wait immediately if we've found that the list has something on it. Also, we don't expect this kthread to accept signals, so we should be using a TASK_UNINTERRUPTIBLE sleep instead. That however, opens us up hung task warnings from the watchdog, so have the schedule_timeout wake up every 60s if there's no callback activity. Reported-by:

commit e461894d upstream. StrongARM core uses RCSR SMR bit to tell to bootloader that it was reset by entering the sleep mode. After we have resumed, there is little point in having that bit enabled. Moreover, if this bit is set before reboot, the bootloader can become confused. Thus clear the SMR bit on resume just before clearing the scratchpad (resume address) register. Signed-off-by:

commit a39128bc upstream. According to erratum 'ERR-7878951' Armada 38x SDHCI controller has different capabilities than the ones shown in its registers: - it doesn't support the voltage switching: it can work either with 3.3V or 1.8V supply - it doesn't support the SDR104 mode - SDR50 mode doesn't need tuning The SDHCI_QUIRK_MISSING_CAPS quirk is used for updating the capabilities accordingly.

commit d4b803c5 upstream. According to erratum 'FE-2946959' both SDR50 and DDR50 modes require specific clock adjustments in SDIO3 Configuration register. However, this register was not part of the device tree binding. Even if the binding can (and will) be extended we still need handling the case where this register was not available. In this case we use the SDHCI_QUIRK_MISSING_CAPS quirk remove them from the capabilities.

commit 14460dba upstream. Current code checks "clk_delay_cycles > 0" to know whether the optional "mrvl,clk_delay_cycles" is set or not. But of_property_read_u32() doesn't touch clk_delay_cycles if the property is not set. And type of clk_delay_cycles is u32, so we may always set pdata->clk_delay_cycles as a random value. This patch fix this problem by check the return value of of_property_read_u32() to know whether the optional clk-delay-cycles is set or not. Signed-off-by:

commit 42b8ce6f upstream. `do_cmd_ioctl()` in "comedi_fops.c" handles the `COMEDI_CMD` ioctl. This returns `-EAGAIN` if it has copied a modified `struct comedi_cmd` back to user-space. (This occurs when the low-level Comedi driver's `do_cmdtest()` handler returns non-zero to indicate a problem with the contents of the `struct comedi_cmd`, or when the `struct comedi_cmd` has the `CMDF_BOGUS` flag set.) `compat_cmd()` in "comedi_compat32.c" handles the 32-bit compatible version of the `COMEDI_CMD` ioctl. Currently, it never copies a 32-bit compatible version of `struct comedi_cmd` back to user-space, which is at odds with the way the regular `COMEDI_CMD` ioctl is handled. To fix it, change `compat_cmd()` to copy a 32-bit compatible version of the `struct comedi_cmd` back to user-space when the main ioctl handler returns `-EAGAIN`. Signed-off-by:

commit 3bb10f60 upstream. This patch is to fix a race condition that may cause an unhandled irq, which results in big sdhci interrupt numbers and endless "mmc1: got irq while runtime suspended" msgs before v3.15. Consider following scenario: CPU0 CPU1 sdhci_pxav3_runtime_suspend() spin_lock_irqsave(&host->lock, flags); sdhci_irq() spining on the &host->lock host->runtime_suspended = true; spin_unlock_irqrestore(&host->lock, flags); get the &host->lock runtime_suspended is true now return IRQ_NONE; Fix this race by using the core sdhci.c supplied sdhci_runtime_suspend_host() in runtime suspend hook which will disable card interrupts. We also use the sdhci_runtime_resume_host() in the runtime resume hook accordingly. Signed-off-by:

commit 4690555e upstream. Since kernel 3.14 the backlight control has been broken on various Samsung Atom based netbooks. This has been bisected and this problem happens since commit b35684b8 ("drm/i915: do full backlight setup at enable time") This has been reported and discussed in detail here: http://lists.freedesktop.org/archives/intel-gfx/2014-July/049395.html Unfortunately no-one has been able to fix this. This only affects Samsung Atom netbooks, and the Linux kernel and the BIOS of those laptops have never worked well together. All affected laptops already have a quirk to avoid using the standard acpi-video interface and instead use the samsung specific SABI interface which samsung-laptop uses. It seems that recent fixes to the i915 driver have also broken backlight control through the SABI interface. The intel_backlight driver OTOH works fine, and also allows for finer grained backlight control. So add a new use_native_backlight quirk, and replace the broken_acpi_video quirk with this quirk for affected models. This new quirk disables acpi-video as before and also stops samsung-laptop from registering the SABI based samsung_laptop backlight interface, leaving only the working intel_backlight interface. This commit enables this new quirk for 3 models which are known to be affected, chances are that it needs to be used on other models too.

commit 3443a3bc upstream. When the superblock is modified in a transaction, the commonly modified fields are not actually copied to the superblock buffer to avoid the buffer lock becoming a serialisation point. However, there are some other operations that modify the superblock fields within the transaction that don't directly log to the superblock but rely on the changes to be applied during the transaction commit (to minimise the buffer lock hold time). When we do this, we fail to mark the buffer log item as being a superblock buffer and that can lead to the buffer not being marked with the corect type in the log and hence causing recovery issues. Fix it by setting the type correctly, similar to xfs_mod_sb()... Tested-by:

commit 0d612fb5 upstream. Jan Kara reported that log recovery was finding buffers with invalid types in them. This should not happen, and indicates a bug in the logging of buffers. To catch this, add asserts to the buffer formatting code to ensure that the buffer type is in range when the transaction is committed. We don't set a type on buffers being marked stale - they are not going to get replayed, the format item exists only for recovery to be able to prevent replay of the buffer, so the type does not matter. Hence that needs special casing here. Reported-by:

commit 6d1cff2a upstream. We hit use after free on dereferncing pointer to task_smack struct in smk_of_task() called from smack_task_to_inode(). task_security() macro uses task_cred_xxx() to get pointer to the task_smack. task_cred_xxx() could be used only for non-pointer members of task's credentials. It cannot be used for pointer members since what they point to may disapper after dropping RCU read lock. Mainly task_security() used this way: smk_of_task(task_security(p)) Intead of this introduce function smk_of_task_struct() which takes task_struct as argument and returns pointer to smk_known struct and do this under RCU read lock. Bogus task_security() macro is not used anymore, so remove it.

commit c6ce1943 upstream. Hi, If you can manage to submit an async write as the first async I/O from the context of a process with realtime scheduling priority, then a cfq_queue is allocated, but filed into the wrong async_cfqq bucket. It ends up in the best effort array, but actually has realtime I/O scheduling priority set in cfqq->ioprio. The reason is that cfq_get_queue assumes the default scheduling class and priority when there is no information present (i.e. when the async cfqq is created): static struct cfq_queue * cfq_get_queue(struct cfq_data *cfqd, bool is_sync, struct cfq_io_cq *cic, struct bio *bio, gfp_t gfp_mask) { const int ioprio_class = IOPRIO_PRIO_CLASS(cic->ioprio); const int ioprio = IOPRIO_PRIO_DATA(cic->ioprio); cic->ioprio starts out as 0, which is "invalid". So, class of 0 (IOPRIO_CLASS_NONE) is passed to cfq_async_queue_prio like so: async_cfqq = cfq_async_queue_prio(cfqd, ioprio_class, ioprio); static struct cfq_queue ** cfq_async_queue_prio(struct cfq_data *cfqd, int ioprio_class, int ioprio) { switch (ioprio_class) { case IOPRIO_CLASS_RT: return &cfqd->async_cfqq[0][ioprio]; case IOPRIO_CLASS_NONE: ioprio = IOPRIO_NORM; /* fall through */ case IOPRIO_CLASS_BE: return &cfqd->async_cfqq[1][ioprio]; case IOPRIO_CLASS_IDLE: return &cfqd->async_idle_cfqq; default: BUG(); } } Here, instead of returning a class mapped from the process' scheduling priority, we get back the bucket associated with IOPRIO_CLASS_BE. Now, there is no queue allocated there yet, so we create it: cfqq = cfq_find_alloc_queue(cfqd, is_sync, cic, bio, gfp_mask); That function ends up doing this: cfq_init_cfqq(cfqd, cfqq, current->pid, is_sync); cfq_init_prio_data(cfqq, cic); cfq_init_cfqq marks the priority as having changed. Then, cfq_init_prio data does this: ioprio_class = IOPRIO_PRIO_CLASS(cic->ioprio); switch (ioprio_class) { default: printk(KERN_ERR "cfq: bad prio %x\n", ioprio_class); case IOPRIO_CLASS_NONE: /* * no prio set, inherit CPU scheduling settings */ cfqq->ioprio = task_nice_ioprio(tsk); cfqq->ioprio_class = task_nice_ioclass(tsk); break; So we basically have two code paths that treat IOPRIO_CLASS_NONE differently, which results in an RT async cfqq filed into a best effort bucket. Attached is a patch which fixes the problem. I'm not sure how to make it cleaner. Suggestions would be welcome. Signed-off-by:

commit 1c7e36bf upstream. With commit '7dedd346: ARM: OMAP2+: hwmod: Fix a crash in _setup_reset() with DEBUG_LL' we moved from parsing cmdline to identify uart used for earlycon to using the requsite hwmod CONFIG_DEBUG_OMAPxUARTy FLAGS. On DRA7 UART3 hwmod doesn't have this flag enabled, and atleast on BeagleBoard-X15, where we use UART3 for console, boot fails with DEBUG_LL enabled. Enable DEBUG_OMAP4UART3_FLAGS for UART3 hwmod. For using DEBUG_LL, enable CONFIG_DEBUG_OMAP4UART3 in menuconfig. Fixes: 90020c7b ("ARM: OMAP: DRA7: hwmod: Create initial DRA7XX SoC data") Reviewed-by:

commit 478913fd upstream. The driver mismatched 'num_supplicants' with 'num_supplies' of power_supply structure. It provided list of supplicants (power_supply.supplied_to) but did not set the number of supplicants. Instead it set the num_supplies which is used when iterating over number of supplies (power_supply.supplied_from). As a result the list of supplicants was ignored by core because its size was 0.

commit faeed51b upstream. enable_irq_wakeup returns 0 in case it correctly enabled the IRQ to generate the wakeup event (and thus resume should call disable_irq_wake). Currently gpio-charger driver has this logic inverted. Correct that thus correcting enable/disable_irq_wake() calls balance. Signed-off-by:
