+Subject: powerpc/ptrace: Simplify vr_get/set() to avoid GCC warning
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+GCC 8 warns about the logic in vr_get/set(), which with -Werror breaks
+the build:
+
+ In function ‘user_regset_copyin’,
+ inlined from ‘vr_set’ at arch/powerpc/kernel/ptrace.c:628:9:
+ include/linux/regset.h:295:4: error: ‘memcpy’ offset [-527, -529] is
+ out of the bounds [0, 16] of object ‘vrsave’ with type ‘union
+ ’ [-Werror=array-bounds]
+ arch/powerpc/kernel/ptrace.c: In function ‘vr_set’:
+ arch/powerpc/kernel/ptrace.c:623:5: note: ‘vrsave’ declared here
+ } vrsave;
+
+This has been identified as a regression in GCC, see GCC bug 88273.
+
+However we can avoid the warning and also simplify the logic and make
+it more robust.
+
+Currently we pass -1 as end_pos to user_regset_copyout(). This says
+"copy up to the end of the regset".
+
+The definition of the regset is:
+ [REGSET_VMX] = {
+ .core_note_type = NT_PPC_VMX, .n = 34,
+ .size = sizeof(vector128), .align = sizeof(vector128),
+ .active = vr_active, .get = vr_get, .set = vr_set
+ },
+
+The end is calculated as (n * size), ie. 34 * sizeof(vector128).
+
+In vr_get/set() we pass start_pos as 33 * sizeof(vector128), meaning
+we can copy up to sizeof(vector128) into/out-of vrsave.
+
+The on-stack vrsave is defined as:
+ union {
+ elf_vrreg_t reg;
+ u32 word;
+ } vrsave;
+
+And elf_vrreg_t is:
+ typedef __vector128 elf_vrreg_t;
+
+So there is no bug, but we rely on all those sizes lining up,
+otherwise we would have a kernel stack exposure/overwrite on our
+hands.
+
+Rather than relying on that we can pass an explict end_pos based on
+the sizeof(vrsave). The result should be exactly the same but it's
+more obviously not over-reading/writing the stack and it avoids the
+compiler warning.

-WARNING
-This patch works with gcc versions 8.1+ and with kernel version 4.13+ and
should
-NOT be applied when compiling on older versions of gcc due to key name changes
-of the march flags introduced with the version 4.9 release of gcc.[1]
-
-Use the older version of this patch hosted on the same github for older
-versions of gcc.
-
-FEATURES
-This patch adds additional CPU options to the Linux kernel accessible under:
- Processor type and features --->
- Processor family --->
-
-The expanded microarchitectures include:
-* AMD Improved K8-family
-* AMD K10-family
-* AMD Family 10h (Barcelona)
-* AMD Family 14h (Bobcat)
-* AMD Family 16h (Jaguar)
-* AMD Family 15h (Bulldozer)
-* AMD Family 15h (Piledriver)
-* AMD Family 15h (Steamroller)
-* AMD Family 15h (Excavator)
-* AMD Family 17h (Zen)
-* Intel Silvermont low-power processors
-* Intel 1st Gen Core i3/i5/i7 (Nehalem)
-* Intel 1.5 Gen Core i3/i5/i7 (Westmere)
-* Intel 2nd Gen Core i3/i5/i7 (Sandybridge)
-* Intel 3rd Gen Core i3/i5/i7 (Ivybridge)
-* Intel 4th Gen Core i3/i5/i7 (Haswell)
-* Intel 5th Gen Core i3/i5/i7 (Broadwell)
-* Intel 6th Gen Core i3/i5/i7 (Skylake)
-* Intel 6th Gen Core i7/i9 (Skylake X)
-* Intel 8th Gen Core i3/i5/i7 (Cannon Lake)
-* Intel 8th Gen Core i7/i9 (Ice Lake)
-
-It also offers to compile passing the 'native' option which, "selects the CPU
-to generate code for at compilation time by determining the processor type of
-the compiling machine. Using -march=native enables all instruction subsets
-supported by the local machine and will produce code optimized for the local
-machine under the constraints of the selected instruction set."[3]
-
-MINOR NOTES
-This patch also changes 'atom' to 'bonnell' in accordance with the gcc v4.9
-changes. Note that upstream is using the deprecated 'match=atom' flags when I
-believe it should use the newer 'march=bonnell' flag for atom processors.[2]
-
-It is not recommended to compile on Atom-CPUs with the 'native' option.[4] The
-recommendation is to use the 'atom' option instead.
-
-BENEFITS
-Small but real speed increases are measurable using a make endpoint comparing
-a generic kernel to one built with one of the respective microarchs.
-
-See the following experimental evidence supporting this statement:
-https://github.com/graysky2/kernel_gcc_patch
-
-REQUIREMENTS
-linux version >=3.15
-gcc version >=8.1
-
-ACKNOWLEDGMENTS
-This patch builds on the seminal work by Jeroen.[5]

+WARNING
+This patch works with gcc versions 8.1+ and with kernel version 4.13+ and
should
+NOT be applied when compiling on older versions of gcc due to key name changes
+of the march flags introduced with the version 4.9 release of gcc.[1]
+
+Use the older version of this patch hosted on the same github for older
+versions of gcc.
+
+FEATURES
+This patch adds additional CPU options to the Linux kernel accessible under:
+ Processor type and features --->
+ Processor family --->
+
+The expanded microarchitectures include:
+* AMD Improved K8-family
+* AMD K10-family
+* AMD Family 10h (Barcelona)
+* AMD Family 14h (Bobcat)
+* AMD Family 16h (Jaguar)
+* AMD Family 15h (Bulldozer)
+* AMD Family 15h (Piledriver)
+* AMD Family 15h (Steamroller)
+* AMD Family 15h (Excavator)
+* AMD Family 17h (Zen)
+* Intel Silvermont low-power processors
+* Intel 1st Gen Core i3/i5/i7 (Nehalem)
+* Intel 1.5 Gen Core i3/i5/i7 (Westmere)
+* Intel 2nd Gen Core i3/i5/i7 (Sandybridge)
+* Intel 3rd Gen Core i3/i5/i7 (Ivybridge)
+* Intel 4th Gen Core i3/i5/i7 (Haswell)
+* Intel 5th Gen Core i3/i5/i7 (Broadwell)
+* Intel 6th Gen Core i3/i5/i7 (Skylake)
+* Intel 6th Gen Core i7/i9 (Skylake X)
+* Intel 8th Gen Core i3/i5/i7 (Cannon Lake)
+* Intel 8th Gen Core i7/i9 (Ice Lake)
+
+It also offers to compile passing the 'native' option which, "selects the CPU
+to generate code for at compilation time by determining the processor type of
+the compiling machine. Using -march=native enables all instruction subsets
+supported by the local machine and will produce code optimized for the local
+machine under the constraints of the selected instruction set."[3]
+
+MINOR NOTES
+This patch also changes 'atom' to 'bonnell' in accordance with the gcc v4.9
+changes. Note that upstream is using the deprecated 'match=atom' flags when I
+believe it should use the newer 'march=bonnell' flag for atom processors.[2]
+
+It is not recommended to compile on Atom-CPUs with the 'native' option.[4] The
+recommendation is to use the 'atom' option instead.
+
+BENEFITS
+Small but real speed increases are measurable using a make endpoint comparing
+a generic kernel to one built with one of the respective microarchs.
+
+See the following experimental evidence supporting this statement:
+https://github.com/graysky2/kernel_gcc_patch
+
+REQUIREMENTS
+linux version >=3.15
+gcc version >=8.1
+
+ACKNOWLEDGMENTS
+This patch builds on the seminal work by Jeroen.[5]

+From: Anthony G. Basile
+
+This patch adds support for a restricted user-controlled namespace on
+tmpfs filesystem used to house PaX flags. The namespace must be of the
+form user.pax.* and its value cannot exceed a size of 8 bytes.
+
+This is needed even on all Gentoo systems so that XATTR_PAX flags
+are preserved for users who might build packages using portage on
+a tmpfs system with a non-hardened kernel and then switch to a
+hardened kernel with XATTR_PAX enabled.
+
+The namespace is added to any user with Extended Attribute support
+enabled for tmpfs. Users who do not enable xattrs will not have
+the XATTR_PAX flags preserved.
