2016-04-08parisc: Unbreak handling exceptions from kernel modulesHelge Deller4-0/+9
Handling exceptions from modules never worked on parisc. It was just masked by the fact that exceptions from modules don't happen during normal use. When a module triggers an exception in get_user() we need to load the main kernel dp value before accessing the exception_data structure, and afterwards restore the original dp value of the module on exit.

2016-04-08parisc: Fix kernel crash with reversed copy_from_user()Helge Deller1-0/+3
The kernel module testcase (lib/test_user_copy.c) exhibited a kernel crash on parisc if the parameters for copy_from_user were reversed ("illegal reversed copy_to_user" testcase). Fix this potential crash by checking the fault handler if the faulting address is in the exception table.

2016-04-08parisc: Avoid function pointers for kernel exception routinesHelge Deller1-5/+5
We want to avoid the kernel module loader to create function pointers for the kernel fixup routines of get_user() and put_user(). Changing the external reference from function type to int type fixes this. This unbreaks exception handling for get_user() and put_user() when called from a kernel module.

This patch now adds support to the kernel module loader to handle such R_PARISC_PCREL32 relocations for 32- and 64-bit modules. Signed-off-by: Helge Deller <deller@gmx.de>

Leave debugfs and superblock code as is for now.

2016-04-08mpls: find_outdev: check for err ptr in addition to NULL checkRoopa Prabhu1-0/+3
find_outdev calls inet{,6}_fib_lookup_dev() or dev_get_by_index() to find the output device. In case of an error, inet{,6}_fib_lookup_dev() returns error pointer and dev_get_by_index() returns NULL. But the function only checks for NULL and thus can end up calling dev_put on an ERR_PTR. This patch adds an additional check for err ptr after the NULL check.

In order to guarantee that readers don't race with trace enabling, both should happen under the same mutex. Having two mutexes seems like an overkill, considering that because of the above, they'll have to be acquired together, around trace enabling and char device opening. This patch makes both buffer accesses and readers serialize on msc::buf_mutex and makes sure that 'enabled' flag accesses are also serialized on it.
