To fix this issue, Dave Anglin developed a set of patches which use the proberi assembler instruction to additionally check read access permissions at runtime. Randy Dunlap contributed two patches to fix a minor typo and to explain why a 32-bit compiler is needed although a 64-bit kernel is built. ---------------------------------------------------------------- John David Anglin (8): parisc: Update comments in make_insert_tlb parisc: Check region is readable by user in raw_copy_from_user() parisc: Rename pte_needs_flush() to pte_needs_cache_flush() in cache.c parisc: Define and use set_pte_at() parisc: Try to fixup kernel exception in bad_area_nosemaphore path of do_page_fault() parisc: Drop WARN_ON_ONCE() from flush_cache_vmap parisc: Revise gateway LWS calls to probe user read access parisc: Revise __get_user() to probe user read access Randy Dunlap (2): parisc: Makefile: fix a typo in palo.conf parisc: Makefile: explain that 64BIT requires both 32-bit and 64-bit compilers arch/parisc/Makefile | 6 ++++-- arch/parisc/include/asm/pgtable.h | 7 ++++--- arch/parisc/include/asm/special_insns.h | 28 ++++++++++++++++++++++++++++ arch/parisc/include/asm/uaccess.h | 21 ++++++++++++++++++--- arch/parisc/kernel/cache.c | 6 +++--- arch/parisc/kernel/entry.S | 17 ++++++++++++----- arch/parisc/kernel/syscall.S | 30 +++++++++++++++++++++--------- arch/parisc/lib/memcpy.c | 19 ++++++++++++++++++- arch/parisc/mm/fault.c | 4 ++++ 9 files changed, 112 insertions(+), 26 deletions(-)
