* printk/console: Enhance the check for consoles using init memoryPetr Mladek2017-07-271-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | printk_late_init() is responsible for disabling boot consoles that use init memory. It checks the address of struct console for this. But this is not enough. For example, there are several early consoles that have write() method in the init section and struct console in the normal section. They are not disabled and could cause fancy and hard to debug system states. It is even more complicated by the macros EARLYCON_DECLARE() and OF_EARLYCON_DECLARE() where various struct members are set at runtime by the provided setup() function. I have tried to reproduce this problem and forced the classic uart early console to stay using keep_bootcon parameter. In particular I used earlycon=uart,io,0x3f8 keep_bootcon console=ttyS0,115200. The system did not boot: [ 1.570496] PM: Image not found (code -22) [ 1.570496] PM: Image not found (code -22) [ 1.571886] PM: Hibernation image not present or could not be loaded. [ 1.571886] PM: Hibernation image not present or could not be loaded. [ 1.576407] Freeing unused kernel memory: 2528K [ 1.577244] kernel tried to execute NX-protected page - exploit attempt? (uid: 0) The double lines are caused by having both early uart console and ttyS0 console enabled at the same time. The early console stopped working when the init memory was freed. Fortunately, the invalid call was caught by the NX-protexted page check and did not cause any silent fancy problems. This patch adds a check for many other addresses stored in struct console. It omits setup() and match() that are used only when the console is registered. Therefore they have already been used at this point and there is no reason to use them again.

* printk/console: Always disable boot consoles that use init memory before it ↵Matt Redfearn2017-07-271-11/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | is freed Commit 4c30c6f566c0 ("kernel/printk: do not turn off bootconsole in printk_late_init() if keep_bootcon") added a check on keep_bootcon to ensure that boot consoles were kept around until the real console is registered. This can lead to problems if the boot console data and code are in the init section, since it can be freed before the boot console is unregistered. Commit 81cc26f2bd11 ("printk: only unregister boot consoles when necessary") fixed this a better way. It allowed to keep boot consoles that did not use init data. Unfortunately it did not remove the check of keep_bootcon. This can lead to crashes and weird panics when the bootconsole is accessed after free, especially if page poisoning is in use and the code / data have been overwritten with a poison value. To prevent this, always free the boot console if it is within the init section. In addition, print a warning about that the console is removed prematurely. Finally there is a new comment how to avoid the warning. It replaced an explanation that duplicated a more comprehensive function description few lines above.

The buffer is per-CPU and therefore the size is rather limited. It works quite well for NMI backtraces. But there are longer logs that might get printed in NMI context, for example, lockdep warnings, ftrace_dump_on_oops. The temporary buffer is used to avoid deadlocks caused by logbuf_lock. Also it is needed to avoid races with the other temporary buffer that is used when PRINTK_SAFE_CONTEXT is entered. But the main buffer can be used in NMI if the lock is available and we did not interrupt PRINTK_SAFE_CONTEXT. The lock is checked using raw_spin_is_locked(). It might cause false negatives when the lock is taken on another CPU and this CPU is in the safe context from other reasons. Note that the safe context is used also to get console semaphore or when calling console drivers. For this reason, we do the check in printk_nmi_enter(). It makes the handling consistent for the entire NMI handler and avoids reshuffling of the messages. The patch also defines special printk context that allows to use printk_deferred() in NMI. Note that we could not flush the messages to the consoles because console drivers might use many other internal locks. The newly created vprintk_deferred() disables the preemption only around the irq work handling. It is needed there to keep the consistency between the two per-CPU variables. But there is no reason to disable preemption around vprintk_emit(). Finally, the patch puts back explicit serialization of the NMI backtraces from different CPUs. It was removed by the commit a9edc88093287183ac934b ("x86/nmi: Perform a safe NMI stack trace on all CPUs"). It was not needed because the flushing of the temporary per-CPU buffers was serialized.

For the first time I can remember, this is actually larger than the corresponding branch for 32-bit platforms overall, though that has more individual changes. A significant portion this time is due to added machine support: - Initial support for the Realtek RTD1295 SoC, along with the Zidoo X9S set-top-box - Initial support for Actions Semi S900 and the Bubblegum-96 single-board-cёmputer. - Rockchips support for the rk3399-Firefly single-board-computer gets added, this one stands out for being relatively fast, affordable and well₋supported, compared to many boards that only fall into one or two of the above categories. - Mediatek gains support for the mt6797 mobile-phone SoC platform and corresponding evaluation board. - Amlogic board support gets added for the NanoPi K2 and S905x LibreTech CC single-board computers and the R-Box Pro set-top-box - Allwinner board support gets added for the OrangePi Win, Orangepi Zero Plus 2, NanoPi NEO2 and Orange Pi Prime single board computers and the SoPine system-on-module. - Renesas board support for Salvator-XS and H3ULCB automotive development systems. - Socionext Uniphier board support for LD11-global and LD20-global, whatever those may be. - Broadcom adds support for the new Stingray communication processor in its iProc family, along with two reference boards. Other updates include: - For the hisicon platform, support for Hi3660-Hikey960 gets extended significantly. - Lots of smaller updates for Renesas, Amlogic, Rockchip, UniPhier, Broadcom, Allwinner, Hisilicon, Qualcomm, Marvell, and NXP" * tag 'armsoc-dt64' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (243 commits) ARM64: dts: marvell: armada37xx: Fix timer interrupt specifiers Revert "arm64: dts: marvell: add dma-mask in crypto nodes for 7k/8k" arm64: dts: mediatek: don't include missing file ARM64: dts: meson-gxl: Add Libre Technology CC support dt-bindings: arm: amlogic: Add Libre Technology CC board dt-bindings: add Libre Technology vendor prefix arm64: dts: marvell: enable GICP and ICU on Armada 7K/8K arm64: dts: zte: Use - instead of @ for DT OPP entries arm64: dts: marvell: add gpio support for Armada 7K/8K arm64: dts: marvell: add pinctrl support for Armada 7K/8K arm64: dts: marvell: use new binding for the system controller on cp110 arm64: dts: marvell: remove *-clock-output-names on cp110 arm64: dts: marvell: use new bindings for xor clocks on ap806 arm64: dts: marvell: mcbin: enable the mdio node arm64: dts: Add Actions Semi S900 and Bubblegum-96 dt-bindings: Add vendor prefix for uCRobotics arm64: dts: marvell: add xmdio nodes for 7k/8k arm64: dts: marvell: add a comment on the cp110 slave node status arm64: dts: marvell: remove cpm crypto nodes from dts files arm64: dts: marvell: cp110: enable the crypto engine at the SoC level ...

The patch to remove the parsing of the property is getting merged through the crypto tree. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
