2018-04-27i2c: dev: prevent ZERO_SIZE_PTR deref in i2cdev_ioctl_rdwr()Alexander Popov
i2cdev_ioctl_rdwr() allocates i2c_msg.buf using memdup_user(), which returns ZERO_SIZE_PTR if i2c_msg.len is zero. Currently i2cdev_ioctl_rdwr() always dereferences the buf pointer in case of I2C_M_RD | I2C_M_RECV_LEN transfer. That causes a kernel oops in case of zero len. Let's check the len against zero before dereferencing buf pointer. This issue was triggered by syzkaller.

2018-04-27cpufreq: powernv: Fix hardlockup due to synchronous smp_call in timer interruptShilpasri G Bhat
gpstate_timer_handler() uses synchronous smp_call to set the pstate on the requested core.

We can ensure that the timer always runs on one of the policy-cpus. If the timer gets migrated to a cpu outside the policy then re-queue it back on the policy->cpus. This way we can get rid of the smp-call which was being used to set the pstate on the policy->cpus.

2018-04-26mtd: rawnand: marvell: fix the chip-select DT parsing logicMiquel Raynal
The block responsible of parsing the DT for the number of chip-select lines uses an 'if/else if/else if' block. The content of the second and third 'else if' conditions are: 1/ the actual condition to enter the sub-block and 2/ the operation to do in this sub-block. [...] else if (condition1_to_enter && action1() == failed) raise_error(); else if (condition2_to_enter && action2() == failed) raise_error(); [...] In case of failure, the sub-block is entered and an error raised. Otherwise, in case of success, the code would continue erroneously in the next 'else if' statement because it did not failed (and did not enter the first 'else if' sub-block). The first 'else if' refers to legacy bindings while the second 'else if' refers to new bindings. The second 'else if', which is entered erroneously, checks for the 'reg' property, which, for old bindings, does not mean anything because it would not be the number of CS available, but the regular register map of almost any DT node. This being said, the content of the 'reg' property being the register map offset and length, it has '2' values, so the number of CS in this situation is assumed to be '2'. When running nand_scan_ident() with 2 CS, the core will check for an array of chips. It will first issue a RESET and then a READ_ID. Of course this will trigger two timeouts because there is no chip in front of the second CS: [ 1.367460] marvell-nfc f2720000.nand: Timeout on CMDD (NDSR: 0x00000080) [ 1.474292] marvell-nfc f2720000.nand: Timeout on CMDD (NDSR: 0x00000280) Indeed, this is harmless and the core will then assume there is only one valid CS. Fix the logic in the whole block by entering each sub-block just on the 'is legacy' condition, doing the action inside the sub-block. This way, when the action succeeds, the whole block is left. Furthermore, for both the old bindings and the new bindings the same logic was applied to retrieve the number of CS lines: using of_get_property() to get a size in bytes, converted in the actual number of lines by dividing it per sizeof(u32) (4 bytes). This is fine for the 'reg' property which is a list of the CS IDs but not for the 'num-cs' property which is directly the value of the number of CS. Anyway, no existing DT uses another value than 'num-cs = <1>' and no other value has ever been supported by the old driver (pxa3xx_nand.c). Remove this condition and apply a number of 1 CS anyway, as already described in the bindings. Finally, the 'reg' property of a 'nand' node (with the new bindings) gives the IDs of each CS line in use. marvell_nand.c driver first look at the number of CS lines that are present in this property. Better use of_property_count_elems_of_size() than dividing by 4 the size of the number of bytes returned by of_get_property().

2018-04-26HISI LPC: Add Kconfig MFD_CORE dependencyJohn Garry
For ACPI support of the HiSilicon LPC driver we depend on MFD_CORE config. Currently the HiSi LPC Kconfig entry does not define this dependency, so add it. The reason for depending on MFD_CORE in the driver is that we model the LPC host as an MFD, in that a platform device will be created for each device on the bus. We do this as we need to modify the resources of these derived platform devices, something which we should not do to the original devices created in the ACPI scan.

2018-04-26Revert: Unify CLOCK_MONOTONIC and CLOCK_BOOTTIMEThomas Gleixner
Revert commits 92af4dcb4e1c ("tracing: Unify the "boot" and "mono" tracing clocks") 127bfa5f4342 ("hrtimer: Unify MONOTONIC and BOOTTIME clock behavior") 7250a4047aa6 ("posix-timers: Unify MONOTONIC and BOOTTIME clock behavior") d6c7270e913d ("timekeeping: Remove boot time specific code") f2d6fdbfd238 ("Input: Evdev - unify MONOTONIC and BOOTTIME clock behavior") d6ed449afdb3 ("timekeeping: Make the MONOTONIC clock behave like the BOOTTIME clock") 72199320d49d ("timekeeping: Add the new CLOCK_MONOTONIC_ACTIVE clock") As stated in the pull request for the unification of CLOCK_MONOTONIC and CLOCK_BOOTTIME, it was clear that we might have to revert the change. As reported by several folks systemd and other applications rely on the documented behaviour of CLOCK_MONOTONIC on Linux and break with the above changes. After resume daemons time out and other timeout related issues are observed. Rafael compiled this list: * systemd kills daemons on resume, after >WatchdogSec seconds of suspending (Genki Sky). [Verified that that's because systemd uses CLOCK_MONOTONIC and expects it to not include the suspend time.] * systemd-journald misbehaves after resume: systemd-journald[7266]: File /var/log/journal/016627c3c4784cd4812d4b7e96a34226/system.journal corrupted or uncleanly shut down, renaming and replacing. (Mike Galbraith). * NetworkManager reports "networking disabled" and networking is broken after resume 50% of the time (Pavel). [May be because of systemd.] * MATE desktop dims the display and starts the screensaver right after system resume (Pavel). * Full system hang during resume (me). [May be due to systemd or NM or both.] That happens on debian and open suse systems. It's sad, that these problems were neither catched in -next nor by those folks who expressed interest in this change. Reported-by: Rafael J.

2018-04-26ARM: amba: Fix race condition with driver_overrideGeert Uytterhoeven
The driver_override implementation is susceptible to a race condition when different threads are reading vs storing a different driver override. Add locking to avoid this race condition. Cfr. commits 6265539776a0810b ("driver core: platform: fix race condition with driver_override") and 9561475db680f714 ("PCI: Fix race condition with driver_override").

2018-04-26ARM: amba: Make driver_override output consistent with other busesGeert Uytterhoeven
For AMBA devices with unconfigured driver override, the "driver_override" sysfs virtual file is empty, while it contains "(null)" for platform and PCI devices. Make AMBA consistent with other buses by dropping the test for a NULL pointer. Note that contrary to popular belief, sprintf() handles NULL pointers fine; they are printed as "(null)".
