interconnect: qcom: icc-rpmh: Ensure floor BW is enforced for all nodes

2021-08-12T11:32:25+00:00

commit ce5a595744126be4f1327e29e3c5ae9aac6b38d5 upstream. We currently only enforce BW floors for a subset of nodes in a path. All BCMs that need updating are queued in the pre_aggregate/aggregate phase. The first set() commits all queued BCMs and subsequent set() calls short-circuit without committing anything. Since the floor BW isn't set in sum_avg/max_peak until set(), then some BCMs are committed before their associated nodes reflect the floor. Set the floor as each node is being aggregated. This ensures that all all relevant floors are set before the BCMs are committed.

interconnect: Always call pre_aggregate before aggregate

2021-08-12T11:32:25+00:00

commit 73606ba9242f8e32023699b500b7922b4cf2993c upstream. The pre_aggregate callback isn't called in all cases before calling aggregate. Add the missing calls so providers can rely on consistent framework behavior.

interconnect: Zero initial BW after sync-state

2021-08-12T11:32:25+00:00

commit 456a9dace42ecfcec7ce6e17c18d1985d628dcd0 upstream. The initial BW values may be used by providers to enforce floors. Zero these values after sync-state so that providers know when to stop enforcing them.

commit 85b1ebfea2b0d8797266bcc6f04b6cc87e38290a upstream. The expression sizeof(**ptr) for the void **ptr is just 1 rather than the size of a pointer. Fix this by using sizeof(*ptr).

Pull CFI on arm64 support from Kees Cook: "This builds on last cycle's LTO work, and allows the arm64 kernels to be built with Clang's Control Flow Integrity feature. This feature has happily lived in Android kernels for almost 3 years[1], so I'm excited to have it ready for upstream. The wide diffstat is mainly due to the treewide fixing of mismatched list_sort prototypes. Other things in core kernel are to address various CFI corner cases. The largest code portion is the CFI runtime implementation itself (which will be shared by all architectures implementing support for CFI). The arm64 pieces are Acked by arm64 maintainers rather than coming through the arm64 tree since carrying this tree over there was going to be awkward. CFI support for x86 is still under development, but is pretty close. There are a handful of corner cases on x86 that need some improvements to Clang and objtool, but otherwise works well.

treewide: Change list_sort to use const pointers

2021-04-08T23:04:22+00:00

list_sort() internally casts the comparison function passed to it to a different type with constant struct list_head pointers, and uses this pointer to call the functions, which trips indirect call Control-Flow Integrity (CFI) checking. Instead of removing the consts, this change defines the list_cmp_func_t type and changes the comparison function types of all list_sort() callers to use const pointers, thus avoiding type mismatches.
