BugLink: https://bugs.launchpad.net/bugs/1818813 [ Upstream commit 4f68ef64 ] The function cw1200_bss_info_changed() and cw1200_hw_scan() can be concurrently executed. The two functions both access a possible shared variable "frame.skb". This shared variable is freed by dev_kfree_skb() in cw1200_upload_beacon(), which is called by cw1200_bss_info_changed(). The free operation is protected by a mutex lock "priv->conf_mutex" in cw1200_bss_info_changed(). In cw1200_hw_scan(), this shared variable is accessed without the protection of the mutex lock "priv->conf_mutex". Thus, concurrency use-after-free bugs may occur. To fix these bugs, the original calls to mutex_lock(&priv->conf_mutex) and mutex_unlock(&priv->conf_mutex) are moved to the places, which can protect the accesses to the shared variable.

Avoid the misleading error and silently bail out from the function in case the received event is a command status. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1818813 [ Upstream commit 0d640732 ] When we emulate an MMIO instruction, we advance the CPU state within decode_hsr(), before emulating the instruction effects. Having this logic in decode_hsr() is opaque, and advancing the state before emulation is problematic. It gets in the way of applying consistent single-step logic, and it prevents us from being able to fail an MMIO instruction with a synchronous exception. Clean this up by only advancing the CPU state *after* the effects of the instruction are emulated. Cc: Peter Maydell <peter.maydell@linaro.org> Reviewed-by:

BugLink: https://bugs.launchpad.net/bugs/1818813 [ Upstream commit 4f5c85fe ] It was observed that when using seqentional mode contrary to the documentation, the SS bit (which is supposed to only be set if automatic/sequence command completed normally), is sometimes set together with NA (NAK in address phase) causing transfer to falsely be considered successful. My assumption is that this does not happen during manual mode since the controller is stopping its work the moment it sets NA/ND bit in status register. This is not the case in Automatic/Sequentional mode where it is still working to send STOP condition and the actual status we get depends on the time when the ISR is run. This patch changes the order of checking status bits in ISR - error conditions are checked first and only if none of them occurred, the transfer may be considered successful. This is required to introduce using of sequentional mode in next patch. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1818813 [ Upstream commit a868e853 ] After removing an entry from a queue (e.g. reading an event in arm_smmu_evtq_thread()) it is necessary to advance the MMIO consumer pointer to free the queue slot back to the SMMU. A memory barrier is required here so that all reads targetting the queue entry have completed before the consumer pointer is updated. The implementation of queue_inc_cons() relies on a writel() to complete the previous reads, but this is incorrect because writel() is only guaranteed to complete prior writes. This patch replaces the call to writel() with an mb(); writel_relaxed() sequence, which gives us the read->write ordering which we require. Cc: Robin Murphy <robin.murphy@arm.com> Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1818813 [ Upstream commit 84fb6c7f ] It was noticed that unbinding and rebinding the KSZ8851 ethernet resulted in the driver reporting "failed to read device ID" at probe. Probing the reset line with a 'scope while repeatedly attempting to bind the driver in a shell loop revealed that the KSZ8851 RSTN pin is constantly held at zero, meaning the device is held in reset, and does not respond on the SPI bus. Experimentation with the startup delay on the regulator set to 50ms shows that the reset is positively released after 20ms. Schematics for this board are not available, and the traces are buried in the inner layers of the board which makes tracing where the RSTN pin extremely difficult. We can only guess that the RSTN pin is wired to a reset generator chip driven off the ethernet supply, which fits the observed behaviour. Include this delay in the regulator startup delay - effectively treating the reset as a "supply stable" indicator. This can not be modelled as a delay in the KSZ8851 driver since the reset generation is board specific - if the RSTN pin had been wired to a GPIO, reset could be released earlier via the already provided support in the KSZ8851 driver. This also got confirmed by Peter Ujfalusi <peter.ujfalusi@ti.com> based on Blaze schematics that should be very close to SDP4430: TPS22902YFPR is used as the regulator switch (gpio48 controlled): Convert arm boot_lock to raw The VOUT is routed to TPS3808G01DBV. (SCH Note: Threshold set at 90%. Vsense: 0.405V). According to the TPS3808 data sheet the RESET delay time when Ct is open (this is the case in the schema): MIN/TYP/MAX: 12/20/28 ms. Signed-off-by:

In fact, the IRQ 58 on MMP2 seems to be a signal processor: arch/arm/mach-mmp/irqs.h:#define IRQ_MMP2_MSP 58 I'm taking a somewhat educated guess that is probably a copy & paste error from PXA168 or PXA910 and that the real controller in fact hides at address 0xd4031000 and uses an interrupt line multiplexed via IRQ 17. I'm also copying some properties from TWSI1 that were missing or incorrect. Tested on a OLPC XO 1.75 machine, where the RTC is on TWSI2. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1818813 [ Upstream commit 6e803e2e ] The core ftrace code requires that when it is handed the PC of an instrumented function, this PC is the address of the instrumented instruction. This is necessary so that the core ftrace code can identify the specific instrumentation site. Since the instrumented function will be a BL, the address of the instrumented function is LR - 4 at entry to the ftrace code. This fixup is applied in the mcount_get_pc and mcount_get_pc0 helpers, which acquire the PC of the instrumented function. The mcount_get_lr helper is used to acquire the LR of the instrumented function, whose value does not require this adjustment, and cannot be adjusted to anything meaningful. No adjustment of this value is made on other architectures, including arm. However, arm64 adjusts this value by 4. This patch brings arm64 in line with other architectures and removes the adjustment of the LR value. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1818813 [ Upstream commit 336650c7 ] The ad7780 driver previously did not read the correct device output, as it read an outdated value set at initialization. It now updates its voltage on read. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1818813 [ Upstream commit b3a3eafe ] Previously, ad2s90_probe ignored the return code from spi_setup, not handling its possible failure. This patch makes ad2s90_probe check if the code is an error code and, if so, do the following: - Call dev_err with an appropriate error message. - Return the spi_setup's error code. Note: The 'return ret' statement could be out of the 'if' block, but this whole block will be moved up in the function in the patch: 'staging:iio:ad2s90: Move device registration to the end of probe'.

BugLink: https://bugs.launchpad.net/bugs/1818813 [ Upstream commit 5b3f5c40 ] The previous commit, "of: overlay: add missing of_node_get() in __of_attach_node_sysfs" added a missing of_node_get() to __of_attach_node_sysfs(). This results in a refcount imbalance for nodes attached with dlpar_attach_node(). The calling sequence from dlpar_attach_node() to __of_attach_node_sysfs() is: dlpar_attach_node() of_attach_node() __of_attach_node_sysfs() For more detailed description of the node refcount, see commit 68baf692 ("powerpc/pseries: Fix of_node_put() underflow during DLPAR remove").

BugLink: https://bugs.launchpad.net/bugs/1818813 [ Upstream commit 53bb565f ] In the expression "word1 << 16", word1 starts as u16, but is promoted to a signed int, then sign-extended to resource_size_t, which is probably not what was intended. Cast to resource_size_t to avoid the sign extension. This fixes an identical issue as fixed by commit 0b2d7076 ("x86/PCI: Fix Broadcom CNB20LE unintended sign extension") back in 2014. Detected by CoverityScan, CID#138749, 138750 ("Unintended sign extension") Fixes: 3f6ea84a ("PCI: read memory ranges out of Broadcom CNB20LE host bridge") Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1818813 [ Upstream commit 216f0efd ] Before this patch, recovery would cause all callbacks to be delayed, put on a queue, and afterward they were all queued to the callback work queue. This patch does the same thing, but occasionally takes a break after 25 of them so it won't swamp the CPU at the expense of other RT processes like corosync. Signed-off-by:
