The AMBA bus should also use of_device_make_bus_id() when populating device out of device tree data. This patch makes the function non-static, and adds a suitable prototype in of_device.h Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

This patch fixes some instances where interrupt specifiers are dereferenced directly instead of doing a be32_to_cpu() conversion first. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

The flat tree code wasn't fixing the endianness on phandle values when unflattening the tree, and the code in drivers/of wasn't always doing a be32_to_cpu before trying to dereference the phandle values. This patch fixes them. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

With the current string comparison, a device tree compatible of "foo-bar" would match as compatible with a driver looking for "foo". This patch fixes the function to use the of_compat_cmp() macro so that it does the right thing on all platforms (If sparc ever uses this code, it will still want the strncasecmp() behaviour).

This list used was by only two platforms with all other platforms defining an own list of valid bus id's to pass to of_platform_bus_probe. This patch: i) copies the default list to the two platforms that depended on it (powerpc) ii) remove the usage of of_default_bus_ids in of_platform_bus_probe iii) removes the definition of the list from all architectures that defined it Passing a NULL 'matches' parameter to of_platform_bus_probe is still valid; the function returns no error in that case as the NULL value is equivalent to an empty list. Signed-off-by: Jonas Bonn <jonas@southpole.se> [grant.likely@secretlab.ca: added __initdata annotations, warn on and return error on missing match table, and fix whitespace errors] Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

There is an unlikely chance of this situation is occurring, but it is easy to protect against. If a matching entry cannot be found in the of_match_table, then don't bind the driver. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

It is mostly unused now. Sparc has a few defines left in it, but they can be moved to other headers.

Both of_bus_type and of_platform_bus_type are just #define aliases for the platform bus. This patch removes all references to them and switches to the of_register_platform_driver()/of_unregister_platform_driver() API for registering. Subsequent patches will convert each user of of_register_platform_driver() into plain platform_drivers without the of_platform_driver shim. At which point the of_register_platform_driver()/of_unregister_platform_driver() functions can be removed. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S. Miller <davem@davemloft.net>

of_platform_bus was being used in the same manner as the platform_bus. The only difference being that of_platform_bus devices are generated from data in the device tree, and platform_bus devices are usually statically allocated in platform code. Having them separate causes the problem of device drivers having to be registered twice if it was possible for the same device to appear on either bus. This patch removes of_platform_bus_type and registers all of_platform bus devices and drivers on the platform bus instead. A previous patch made the of_device structure an alias for the platform_device structure, and a shim is used to adapt of_platform_drivers to the platform bus. After all of of_platform_bus drivers are converted to be normal platform drivers, the shim code can be removed. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

Fix the security problem in the CIFS filesystem DNS lookup code in which a malicious redirect could be installed by a random user by simply adding a result record into one of their keyrings with add_key() and then invoking a CIFS CFS lookup [CVE-2010-2524]. This is done by creating an internal keyring specifically for the caching of DNS lookups. To enforce the use of this keyring, the module init routine creates a set of override credentials with the keyring installed as the thread keyring and instructs request_key() to only install lookup result keys in that keyring. The override is then applied around the call to request_key(). This has some additional benefits when a kernel service uses this module to request a key: (1) The result keys are owned by root, not the user that caused the lookup. (2) The result keys don't pop up in the user's keyrings. (3) The result keys don't come out of the quota of the user that caused the lookup. The keyring can be viewed as root by doing cat /proc/keys: 2a0ca6c3 I----- 1 perm 1f030000 0 0 keyring .dns_resolver: 1/4 It can then be listed with 'keyctl list' by root. # keyctl list 0x2a0ca6c3 1 key in keyring: 726766307: --alswrv 0 0 dns_resolver: foo.bar.com Signed-off-by: David Howells <dhowells@redhat.com> Reviewed-and-Tested-by: Jeff Layton <jlayton@redhat.com> Acked-by: Steve French <smfrench@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

In the CONFIG_AUDITSYSCALL fast-path for x86 64-bit system calls, we can pass a bad return value and/or error indication for the system call to audit_syscall_exit(). This happens when TIF_NEED_RESCHED was set as the system call returned, so we went out to schedule() and came back to the exit-audit fast-path. The fix is to reload the user return value register from the pt_regs before using it for audit_syscall_exit(). Both the 32-bit kernel's fast path and the 64-bit kernel's 32-bit system call fast paths work slightly differently, so that they always leave the fast path entirely to reschedule and don't return there, so they don't have the analogous bugs.

Immediately following an exit from the kdb shell the kgdb_connected variable should be set to zero, unless there are breakpoints planted. If the kgdb_connected variable is not zeroed out with kdb, it is impossible to turn off kdb. This patch is merely a work around for now, the real fix will check for the breakpoints.

In the process of merging kdb to the mainline, the kdb lsmod command stopped printing the base load address of kernel modules. This is needed for using kdb in conjunction with external tools such as gdb. Simply restore the functionality by adding a kdb_printf for the base load address of the kernel modules.

The gdbserial protocol handler should return an empty packet instead of an error string when ever it responds to a command it does not implement. The problem cases come from a debugger client sending qTBuffer, qTStatus, qSearch, qSupported. The incorrect response from the gdbstub leads the debugger clients to not function correctly. Recent versions of gdb will not detach correctly as a result of this behavior. Signed-off-by: Jason Wessel <jason.wessel@windriver.com> Signed-off-by: Dongdong Deng <dongdong.deng@windriver.com>
