| * kbuild: use assignment instead of define ... endef for filechk_* rulesMasahiro Yamada2019-01-062-14/+5
| | | | | | | | | | | | | | | | | | | | | | | | You do not have to use define ... endef for filechk_* rules. For simple cases, the use of assignment looks cleaner, IMHO. I updated the usage for scripts/Kbuild.include in case somebody misunderstands the 'define ... endif' is the requirement.

| * kbuild: change filechk to surround the given command with { }Masahiro Yamada2019-01-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | filechk_* rules often consist of multiple 'echo' lines. They must be surrounded with { } or ( ) to work correctly. Otherwise, only the string from the last 'echo' would be written into the target. Let's take care of that in the 'filechk' in scripts/Kbuild.include to clean up filechk_* rules.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, CONFIG_JUMP_LABEL just means "I _want_ to use jump label". The jump label is controlled by HAVE_JUMP_LABEL, which is defined like this: #if defined(CC_HAVE_ASM_GOTO) && defined(CONFIG_JUMP_LABEL) # define HAVE_JUMP_LABEL #endif We can improve this by testing 'asm goto' support in Kconfig, then make JUMP_LABEL depend on CC_HAS_ASM_GOTO. Ugly #ifdef HAVE_JUMP_LABEL will go away, and CONFIG_JUMP_LABEL will match to the real kernel capability.

* | Fix 'acccess_ok()' on alpha and SHLinus Torvalds2019-01-062-5/+10

It turns out that the bug wasn't actually in that commit itself (which would have been surprising: it was mostly a no-op), but in how the addition of access_ok() to the strncpy_from_user() and strnlen_user() functions now triggered the case where those functions would test the access of the very last byte of the user address space. The string functions actually did that user range test before too, but they did it manually by just comparing against user_addr_max(). But with user_access_begin() doing the check (using "access_ok()"), it now exposed problems in the architecture implementations of that function. For example, on alpha, the access_ok() helper macro looked like this: #define __access_ok(addr, size) \ ((get_fs().seg & (addr | size | (addr+size))) == 0) and what it basically tests is of any of the high bits get set (the USER_DS masking value is 0xfffffc0000000000). And that's completely wrong for the "addr+size" check. Because it's off-by-one for the case where we check to the very end of the user address space, which is exactly what the strn*_user() functions do. Why? Because "addr+size" will be exactly the size of the address space, so trying to access the last byte of the user address space will fail the __access_ok() check, even though it shouldn't. As a result, the user string accessor functions failed consistently - because they literally don't know how long the string is going to be, and the max access is going to be that last byte of the user address space. Side note: that alpha macro is buggy for another reason too - it re-uses the arguments twice. And SH has another version of almost the exact same bug: #define __addr_ok(addr) \ ((unsigned long __force)(addr) < current_thread_info()->addr_limit.seg) so far so good: yes, a user address must be below the limit. But then: #define __access_ok(addr, size) \ (__addr_ok((addr) + (size))) is wrong with the exact same off-by-one case: the case when "addr+size" is exactly _equal_ to the limit is actually perfectly fine (think "one byte access at the last address of the user address space") The SH version is actually seriously buggy in another way: it doesn't actually check for overflow, even though it did copy the _comment_ that talks about overflow. So it turns out that both SH and alpha actually have completely buggy implementations of access_ok(), but they happened to work in practice (although the SH overflow one is a serious serious security bug, not that anybody likely cares about SH security). This fixes the problems by using a similar macro on both alpha and SH. It isn't trying to be clever, the end address is based on this logic: unsigned long __ao_end = __ao_a + __ao_b - !!__ao_b; which basically says "add start and length, and then subtract one unless the length was zero". We can't subtract one for a zero length, or we'd just hit an underflow instead. For a lot of access_ok() users the length is a constant, so this isn't actually as expensive as it initially looks.

The main issue here is that mainline U-Boot configures EBase to a value near the end of system memory. And with CONFIG_CPU_MIPSR2_IRQ_VI disabled, trap_init() will not allocate a new area to place the exception handler. The original value will be used and the handler will be copied to this location, which might already be used by some userspace application. The MT7688 supports VI - its config3 register is 0x00002420, so VInt (Bit 5) is set. But without setting CONFIG_CPU_MIPSR2_IRQ_VI this bit will not be evaluated to result in "cpu_has_vi" being set. This patch now selects CONFIG_CPU_MIPSR2_IRQ_VI on MT7620/8 which results trap_init() to allocate some memory for the exception handler. Please note that this issue was not seen with the Mediatek U-Boot version, as it does not touch EBase (stays at default of 0x8000.0000). This is strictly also not correct as the kernel (_text) resides here.

This includes some acked platform-specific drivers (serial, etc). This also include DTs for two boards with this SoC, OrangePi 2G and OrangePi i86. - i.MX8 is another new platform (NXP, 4x Cortex-A53 + Cortex-M4, 4K video playback offload). This is the first i.MX 64-bit SoC. - Some minor updates to Samsung boards (adding a few peripherals in DTs). - Small rework for SMP bootup on STi platforms. - A couple of TEE driver fixes. - A couple of new config options (bcm2835 thermal, Uniphier MDMAC) enabled in defconfigs" * tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (27 commits) ARM: multi_v7_defconfig: enable CONFIG_UNIPHIER_MDMAC arm64: defconfig: Re-enable bcm2835-thermal driver MAINTAINERS: Add entry for RDA Micro SoC architecture tty: serial: Add RDA8810PL UART driver ARM: dts: rda8810pl: Add interrupt support for UART dt-bindings: serial: Document RDA Micro UART ARM: dts: rda8810pl: Add timer support ARM: dts: Add devicetree for OrangePi i96 board ARM: dts: Add devicetree for OrangePi 2G IoT board ARM: dts: Add devicetree for RDA8810PL SoC ARM: Prepare RDA8810PL SoC dt-bindings: arm: Document RDA8810PL and reference boards dt-bindings: Add RDA Micro vendor prefix ARM: sti: remove pen_release and boot_lock arm64: dts: exynos: Add Bluetooth chip to TM2(e) boards arm64: dts: imx8mq-evk: enable watchdog arm64: dts: imx8mq: add watchdog devices MAINTAINERS: add i.MX8 DT path to i.MX architecture arm64: add support for i.MX8M EVK board arm64: add basic DTS for i.MX8MQ ...

Unfortunately this was accidentally dropped by commit eb1e6716cc9c ("arm64: defconfig: sync with savedefconfig"). So enable the driver again.
