* cs5535-mfgpt: Add another reset methodRichard Weinberger2013-04-011-4/+37
| | | | | | | | | | | | | | | | | The CS5535/CS5536 MFGPT has no support to reset the device. The current method uses an undocumented bit but does not work on all devices. At least on my ALIX board it completely freezes the board. This new method tries to soft reset all timers by unconfiguring them. But this does not clear the RO setup register and therefore it has to be ignored while probing. Resetting the timers is not only needed on broken BIOSes also when kexec is used. Otherwise the new kernel will find preconfigured timers and odd things will happen. Signed-off-by: Richard Weinberger <richard@nod.at> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes failure during initialization on Lynx Point LP devices. ME driver needs to release the device from the reset only after the FW has completed its flow and indicated it by delivering an interrupt to the host. This is the correct behavior for all the ME devices yet the the previous versions are less susceptive to the implementation that ignored FW reset completion indication.

* fs: Limit sys_mount to only request filesystem modules.Eric W. Biederman2013-03-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modify the request_module to prefix the file system type with "fs-" and add aliases to all of the filesystems that can be built as modules to match. A common practice is to build all of the kernel code and leave code that is not commonly needed as modules, with the result that many users are exposed to any bug anywhere in the kernel. Looking for filesystems with a fs- prefix limits the pool of possible modules that can be loaded by mount to just filesystems trivially making things safer with no real cost. Using aliases means user space can control the policy of which filesystem modules are auto-loaded by editing /etc/modprobe.d/*.conf with blacklist and alias directives. Allowing simple, safe, well understood work-arounds to known problematic software. This also addresses a rare but unfortunate problem where the filesystem name is not the same as it's module name and module auto-loading would not work. While writing this patch I saw a handful of such cases. The most significant being autofs that lives in the module autofs4. This is relevant to user namespaces because we can reach the request module in get_fs_type() without having any special permissions, and people get uncomfortable when a user specified string (in this case the filesystem type) goes all of the way to request_module. After having looked at this issue I don't think there is any particular reason to perform any filtering or permission checks beyond making it clear in the module request that we want a filesystem module. The common pattern in the kernel is to call request_module() without regards to the users permissions. In general all a filesystem module does once loaded is call register_filesystem() and go to sleep. Which means there is not much attack surface exposed by loading a filesytem module unless the filesystem is mounted. In a user namespace filesystems are not mounted unless .fs_flags = FS_USERNS_MOUNT, which most filesystems do not set today.

For PPC64 ABI, actually there is a function descriptors structure. A function descriptor is a three doubleword data structure that contains the following values: * The first doubleword contains the address of the entry point of the function. * The second doubleword contains the TOC base address for the function. * The third doubleword contains the environment pointer for languages such as Pascal and PL/1. So we should call a wapperred dereference_function_descriptor() to get the address of the entry point of the function. Note this is also safe for other architecture after refer to "include/asm-generic/sections.h" since: dereference_function_descriptor(p) always is (p) if without arched definition.

I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually.
