sparc64: Use arch_validate_flags() to validate ADI flag

2021-03-17T16:06:24+00:00

[ Upstream commit 147d8622f2a26ef34beacc60e1ed8b66c2fa457f ] When userspace calls mprotect() to enable ADI on an address range, do_mprotect_pkey() calls arch_validate_prot() to validate new protection flags. arch_validate_prot() for sparc looks at the first VMA associated with address range to verify if ADI can indeed be enabled on this address range. This has two issues - (1) Address range might cover multiple VMAs while arch_validate_prot() looks at only the first VMA, (2) arch_validate_prot() peeks at VMA without holding mmap lock which can result in race condition. arch_validate_flags() from commit c462ac288f2c ("mm: Introduce arch_validate_flags()") allows for VMA flags to be validated for all VMAs that cover the address range given by user while holding mmap lock. This patch updates sparc code to move the VMA check from arch_validate_prot() to arch_validate_flags() to fix above two issues.

local64.h: make mandatory

2021-01-12T19:18:16+00:00

[ Upstream commit 87dbc209ea04645fd2351981f09eff5d23f8e2e9 ] Make mandatory in include/asm-generic/Kbuild and remove all arch/*/include/asm/local64.h arch-specific files since they only #include . This fixes build errors on arch/c6x/ and arch/nios2/ for block/blk-iocost.c. Build-tested on 21 of 25 arch-es. (tools problems on the others) Yes, we could even rename to and change all #includes to use instead.

treewide: Convert macro and uses of section(foo) to section("foo")

2020-10-25T21:51:49+00:00

Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms. Conversion done using the script at: https://lore.kernel.org/lkml/75393e5ddc272dc7403de74d645e6c6e0f4e70eb.camel@perches.com/2-convert_section.pl Signed-off-by: Joe Perches Reviewed-by: Nick Desaulniers Reviewed-by: Miguel Ojeda Signed-off-by: Linus Torvalds
