of: return NUMA_NO_NODE from fallback of_node_to_nid()

2015-08-03T16:29:58Z

commit c8fff7bc5bba6bd59cad40441c189c4efe7190f6 upstream. Node 0 might be offline as well as any other numa node, in this case kernel cannot handle memory allocation and crashes.

of: Fix overflow bug in string property parsing functions

2014-11-14T17:00:13Z

commit a87fa1d81a9fb5e9adca9820e16008c40ad09f33 upstream. The string property read helpers will run off the end of the buffer if it is handed a malformed string property. Rework the parsers to make sure that doesn't happen. At the same time add new test cases to make sure the functions behave themselves. The original implementations of of_property_read_string_index() and of_property_count_strings() both open-coded the same block of parsing code, each with it's own subtly different bugs. The fix here merges functions into a single helper and makes the original functions static inline wrappers around the helper. One non-bugfix aspect of this patch is the addition of a new wrapper, of_property_read_string_array(). The new wrapper is needed by the device_properties feature that Rafael is working on and planning to merge for v3.19. The implementation is identical both with and without the new static inline wrapper, so it just got left in to reduce the churn on the header file. Signed-off-by: Grant Likely Cc: Rafael J.

of: restructure for_each macros to fix compile warnings

2014-02-05T15:51:54Z

Commit 00b2c76a6a "include/linux/of.h: make for_each_child_of_node() reference its args when CONFIG_OF=n" fixed warnings for unused variables, but introduced variable "used uninitialized" warnings. Simply initializing the variables would result in "set but not used" warnings with W=1. Fix both types of warnings by making all the for_each macros unconditional and rely on the dummy static inline functions to initialize and reference any variables.

of: Add empty for_each_available_child_of_node() macro definition

2013-11-03T19:39:58Z

Add this empty macro definition so users can be compiled without excluding this macro call with preprocessor directives when CONFIG_OF is disabled. Signed-off-by: Sylwester Nawrocki Signed-off-by: Kyungmin Park Signed-off-by: Rob Herring

of: Move definition of of_find_next_cache_node into common code.

Since the definition of_find_next_cache_node is architecture independent, the existing definition in powerpc can be moved to driver/of/base.c Cc: Benjamin Herrenschmidt Cc: Grant Likely Cc: Rob Herring Signed-off-by: Sudeep KarkadaNagesha Signed-off-by: Benjamin Herrenschmidt

of: introduce of_get_available_child_count

Some drivers keep counting available child by themselves. So introduce a new simple API like of_get_child_count() but for available childs. Cc: Josh Wu Signed-off-by: Bryan Wu Acked-by: Rob Herring
