git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull CPU hotplug fixes from Thomas Gleixner: "Two SMT/hotplug related fixes: - Prevent crash when HOTPLUG_CPU is disabled and the CPU bringup aborts. This is triggered with the 'nosmt' command line option, but can happen by any abort condition. As the real unplug code is not compiled in, prevent the fail by keeping the CPU in zombie state. - Enforce HOTPLUG_CPU for SMP on x86 to avoid the above situation completely. With 'nosmt' being a popular option it's required to unplug the half brought up sibling CPUs (due to the MCE wreckage) completely" * 'smp-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/smp: Enforce CONFIG_HOTPLUG_CPU when SMP=y cpu/hotplug: Prevent crash when CPU bringup fails on CONFIG_HOTPLUG_CPU=n

2019-03-30leds: trigger: netdev: use memcpy in device_name_storeRasmus Villemoes1-1/+2
If userspace doesn't end the input with a newline (which can easily happen if the write happens from a C program that does write(fd, iface, strlen(iface))), we may end up including garbage from a previous, longer value in the device_name. For example # cat device_name # printf 'eth12' > device_name # cat device_name eth12 # printf 'eth3' > device_name # cat device_name eth32 I highly doubt anybody is relying on this behaviour, so switch to simply copying the bytes (we've already checked that size is < IFNAMSIZ) and unconditionally zero-terminate it; of course, we also still have to strip a trailing newline.

2019-03-29LSM: Revive CONFIG_DEFAULT_SECURITY_* for "make oldconfig"Kees Cook1-0/+38
Commit 70b62c25665f636c ("LoadPin: Initialize as ordered LSM") removed CONFIG_DEFAULT_SECURITY_{SELINUX,SMACK,TOMOYO,APPARMOR,DAC} from security/Kconfig and changed CONFIG_LSM to provide a fixed ordering as a default value. That commit expected that existing users (upgrading from Linux 5.0 and earlier) will edit CONFIG_LSM value in accordance with their CONFIG_DEFAULT_SECURITY_* choice in their old kernel configs. But since users might forget to edit CONFIG_LSM value, this patch revives the choice (only for providing the default value for CONFIG_LSM) in order to make sure that CONFIG_LSM reflects CONFIG_DEFAULT_SECURITY_* from their old kernel configs. Note that since TOMOYO can be fully stacked against the other legacy major LSMs, when it is selected, it explicitly disables the other LSMs to avoid them also initializing since TOMOYO does not expect this currently.

Only after insert_header success, it will be set to 'dir', otherwise 'header->parent' is set to NULL and drop_sysctl_table is called. However in err handling path of get_subdir, drop_sysctl_table also be called on 'new->header' regardless its value of parent pointer. Then put_links is called, which triggers NULL-ptr deref when access member of header->parent. In fact we have multiple error paths which call drop_sysctl_table() there, upon failure on insert_links() we also call drop_sysctl_table().And even in the successful case on __register_sysctl_table() we still always call drop_sysctl_table().This patch fix it.
