This series contains a mix of header hygiene and a security fix for
rsc_table_for_each_entry().
Patch 1 adds rsc_table.h to the REMOTEPROC MAINTAINERS entry, which was
missing since the header was split out from remoteproc.h.
Patches 2-4 clean up remoteproc.h and rsc_table.h: a checkpatch style
fix for function pointer alignment and two SPDX-License-Identifier
conversions replacing the verbose BSD-3-Clause blurb.
Patch 5 fixes an out-of-bounds read in rsc_table_for_each_entry().
table->offset[i] is a u32 from firmware, but was stored as a signed int.
A crafted offset like 0xFFFFFFF0 interpreted as -16 placed hdr 16 bytes
before the table, and the subsequent avail check was silently bypassed
because the negative int promoted to a large size_t. The fix stores the
offset as u32 and validates it with unsigned comparisons before any
pointer arithmetic.
Changes in v3:
- Patches 3, 4: Per Bjorn's review, replace the BSD blurb
entirely rather than adding the SPDX tag alongside it; preserve the
copyright lines in a separate comment block.
- Patches 1, 2, 5: unchanged from v2.
- Link to v2: https://lore.kernel.org/lkml/20260724184132.1878077-1-mukesh.ojha@oss.qualcomm.com/
Changes in v2:
- Rebased it on next-20260723
- Integrated multiple singleton into this series.
