If a transaction that contains a file descriptor fails on a later object, the new file descriptor needs to be closed. If this is a binder file descriptor we would deadlock in flush. If there were no other references to the file at this point release would also be called. Signed-off-by: NArve Hjønnevåg <arve@android.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

This prevents breaking fget_light if a single threaded application allows incoming file descriptors (in replies or on nodes). Should also prevent inserting a file in the wrong files_struct if the receving process execs in the middle of a transaction (between task_get_unused_fd_flags and task_fd_install).

Commit 46e0bb9c ("sched: Print sched_group::__cpu_power in sched_domain_debug") produces a messy dmesg output while attempting to print the sched_group::__cpu_power for each group in the sched_domain hierarchy.

Tetsuo Handa reports seeing the WARN_ON(current->mm == NULL) in security_vm_enough_memory(), when do_execve() is touching the target mm's stack, to set up its args and environment. Yes, a UMH_NO_WAIT or UMH_WAIT_PROC call_usermodehelper() spawns an mm-less kernel thread to do the exec. And in any case, that vm_enough_memory check when growing stack ought to be done on the target mm, not on the execer's mm (though apart from the warning, it only makes a slight tweak to OVERCOMMIT_NEVER behaviour).

This reverts commit f520360d. Tetsuo Handa, running a kernel with CONFIG_DEBUG_PAGEALLOC=y and CONFIG_UEVENT_HELPER_PATH=/sbin/hotplug, has been hitting RCU detected CPU stalls: it's been spinning in the loop where do_execve() counts up the args (but why wasn't fixup_exception working? dunno). The recent change, switching kobject_uevent_env() from UMH_WAIT_EXEC to UMH_NO_WAIT, is broken: the exec uses args on the local stack here, and an env which is kfreed as soon as call_usermodehelper() returns. It very much needs to wait for the exec to be done. An alternative would be to keep the UMH_NO_WAIT, and complicate the code to allocate and free these resources correctly? but no, as GregKH pointed out when making the commit, CONFIG_UEVENT_HELPER_PATH="" is a much better optimization - though some distros are still saying /sbin/hotplug in their .config, yet with no such binary in their initrd or their root.

This patch correctly sets BAU memory mapped registers to point to the sending activation descriptor table and target payload table. The "Broadcast Assist Unit" is used for TLB shootdown in UV. The memory mapped registers that point to sending and receiving memory structures contain node numbers. In one case the __pa() function did not provide the node id of memory on blade zero in configurations where that id is nonzero. In another case, it was assumed that memory was allocated on the local node. That assumption is not true in a configuration in which the node has no memory. Tested on the UV hardware simulator.
