2017-12-31ARM: dts: at91: Remove leading 0x and 0s from bindings notationMathieu Malaterre9-9/+9
Improve the DTS files by removing all the leading "0x" and zeros to fix the following dtc warnings: Warning (unit_address_format): Node /XXX unit name should not have leading "0x" and Warning (unit_address_format): Node /XXX unit name should not have leading 0s Converted using the following command: find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -i -e "s/@\([0-9a-fA-FxX\.;:#]+\)\s*{/@\L\1 {/g" -e "s/@0x\(.*\) {/@\1 {/g" -e "s/@0+\(.*\) {/@\1 {/g" {} +^C For simplicity, two sed expressions were used to solve each warnings separately. To make the regex expression more robust a few other issues were resolved, namely setting unit-address to lower case, and adding a whitespace before the the opening curly brace: https://elinux.org/Device_Tree_Linux#Linux_conventions This will solve as a side effect warning: Warning (simple_bus_reg): Node /XXX@<UPPER> simple-bus unit address format error, expected "<lower>" This is a follow up to commit 4c9847b7375a ("dt-bindings: Remove leading 0x from bindings notation") Reported-by: David Daney <ddaney@caviumnetworks.com> Suggested-by: Rob Herring <robh@kernel.org> Signed-off-by: Mathieu Malaterre <malat@debian.org> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>

2017-11-26ARM: BUG if jumping to usermode address in kernel modeRussell King2-0/+24
Detect if we are returning to usermode via the normal kernel exit paths but the saved PSR value indicates that we are in kernel mode. This could occur due to corrupted stack state, which has been observed with "ftracetest". This ensures that we catch the problem case before we get to user code.

2017-11-22treewide: setup_timer() -> timer_setup()Kees Cook2-4/+4
This converts all remaining cases of the old setup_timer() API into using timer_setup(), where the callback argument is the structure already holding the struct timer_list. These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations. Casting from unsigned long: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr); and forced object casts: void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr); become: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0); Direct function assignments: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback; have a temporary cast added, along with converting the args: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback; And finally, callbacks without a data assignment: void my_callback(unsigned long data) { ... } ... setup_timer(&ptr->my_timer, my_callback, 0); have their argument renamed to verify they're unused during conversion: void my_callback(struct timer_list *unused) { ... } ... timer_setup(&ptr->my_timer, my_callback, 0); The conversion is done with the following Coccinelle script: spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup.cocci @fix_address_of@ expression e;

2017-11-22treewide: init_timer() -> setup_timer()Kees Cook1-2/+1
This mechanically converts all remaining cases of ancient open-coded timer setup with the old setup_timer() API, which is the first step in timer conversions. This has no behavioral changes, since it ultimately just changes the order of assignment to fields of struct timer_list when finding variations of: init_timer(&t); f.function = timer_callback; t.data = timer_callback_arg; to be converted into: setup_timer(&t, timer_callback, timer_callback_arg); The conversion is done with the following Coccinelle script, which is an improved version of scripts/cocci/api/setup_timer.cocci, in the following ways: - assignments-before-init_timer() cases - limit the .data case removal to the specific struct timer_list instance - handling calls by dereference (timer->field vs timer.field) spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/setup_timer.cocci @fix_address_of@ expression e; @@ init_timer( -&(e) +&e , ...) // Match the common cases first to avoid Coccinelle parsing loops with // "... when" clauses. @match_immediate_function_data_after_init_timer@ expression e, func, da; @@ -init_timer +setup_timer ( \(&e\|e\) +, func, da ); ( -\(e.function\|e->function\) = func; -\(e.data\|e->data\) = da; | -\(e.data\|e->data\) = da; -\(e.function\|e->function\) = func; ) @match_immediate_function_data_before_init_timer@ expression e, func, da; @@ ( -\(e.function\|e->function\) = func; -\(e.data\|e->data\) = da; | -\(e.data\|e->data\) = da; -\(e.function\|e->function\) = func; ) -init_timer +setup_timer ( \(&e\|e\) +, func, da ); @match_function_and_data_after_init_timer@ expression e, e2, e3, e4, e5, func, da; @@ -init_timer +setup_timer ( \(&e\|e\) +, func, da ); ... when != func = e2 when != da = e3 ( -e.function = func; ... when != da = e4 -e.data = da; | -e->function = func; ... when != da = e4 -e->data = da; | -e.data = da; ... when != func = e5 -e.function = func; | -e->data = da; ... when != func = e5 -e->function = func; ) @match_function_and_data_before_init_timer@ expression e, e2, e3, e4, e5, func, da; @@ ( -e.function = func; ... when != da = e4 -e.data = da; | -e->function = func; ... when != da = e4 -e->data = da; | -e.data = da; ... when != func = e5 -e.function = func; | -e->data = da; ... when != func = e5 -e->function = func; ) ... when != func = e2 when != da = e3 -init_timer +setup_timer ( \(&e\|e\) +, func, da ); @r1 exists@ expression t; identifier f; position p; @@ f(...) { ... when any init_timer@p(\(&t\|t\)) ... when any } @r2 exists@ expression r1.t; identifier g != r1.f; expression e8; @@ g(...) { ... when any \(t.data\|t->data\) = e8 ... when any } // It is dangerous to use setup_timer if data field is initialized // in another function. @script:python depends on r2@ p << r1.p; @@ cocci.include_match(False) @r3@ expression r1.t, func, e7; position r1.p; @@ ( -init_timer@p(&t); +setup_timer(&t, func, 0UL); ... when != func = e7 -t.function = func; | -t.function = func; ... when != func = e7 -init_timer@p(&t); +setup_timer(&t, func, 0UL); | -init_timer@p(t); +setup_timer(t, func, 0UL); ... when != func = e7 -t->function = func; | -t->function = func; ... when != func = e7 -init_timer@p(t); +setup_timer(t, func, 0UL); ) Signed-off-by: Kees Cook <keescook@chromium.org>

2017-11-21ARM: 8722/1: mm: make STRICT_KERNEL_RWX effective for LPAEPhilip Derrin1-2/+2
Currently, for ARM kernels with CONFIG_ARM_LPAE and CONFIG_STRICT_KERNEL_RWX enabled, the 2MiB pages mapping the kernel code and rodata are writable. They are marked read-only in a software bit (L_PMD_SECT_RDONLY) but the hardware read-only bit is not set (PMD_SECT_AP2). For user mappings, the logic that propagates the software bit to the hardware bit is in set_pmd_at(); but for the kernel, section_update() writes the PMDs directly, skipping this logic. The fix is to set PMD_SECT_AP2 for read-only sections in section_update(), at the same time as L_PMD_SECT_RDONLY.

2017-11-21ARM: 8721/1: mm: dump: check hardware RO bit for LPAEPhilip Derrin1-2/+2
When CONFIG_ARM_LPAE is set, the PMD dump relies on the software read-only bit to determine whether a page is writable. This concealed a bug which left the kernel text section writable (AP2=0) while marked read-only in the software bit. In a kernel with the AP2 bug, the dump looks like this: ---[ Kernel Mapping ]--- 0xc0000000-0xc0200000 2M RW NX SHD 0xc0200000-0xc0600000 4M ro x SHD 0xc0600000-0xc0800000 2M ro NX SHD 0xc0800000-0xc4800000 64M RW NX SHD The fix is to check that the software and hardware bits are both set before displaying "ro". The dump then shows the true perms: ---[ Kernel Mapping ]--- 0xc0000000-0xc0200000 2M RW NX SHD 0xc0200000-0xc0600000 4M RW x SHD 0xc0600000-0xc0800000 2M RW NX SHD 0xc0800000-0xc4800000 64M RW NX SHD Fixes: ded947798469 ("ARM: 8109/1: mm: Modify pte_write and pmd_write logic for LPAE") Signed-off-by: Philip Derrin <philip@cog.systems> Tested-by: Neil Dick <neil@cog.systems> Reviewed-by: Kees Cook <keescook@chromium.org> Cc: stable@vger.kernel.org Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2017-11-21ARM: make decompressor debug output user selectableRussell King1-2/+2
Make the decompressor debug output user selectable, otherwise merely enabling DEBUG_LL causes the decompressor to become board specific, thereby preventing a multi-platform kernel from booting. Enabling DEBUG_LL doesn't cause the kernel itself to become platform specific unless EARLY_PRINTK is enabled, or one of the debugging routines is added in a path that results in it being called.
