2020-07-21dt-bindings: interrupt-controller: Convert mti,gic to DT schemaSerge Semin
Modern device tree bindings are supposed to be created as YAML-files in accordance with DT schema. This commit replaces MIPS GIC legacy bare text binding with YAML file. As before the binding file states that the corresponding dts node is supposed to be compatible with MIPS Global Interrupt Controller indicated by the "mti,gic" compatible string and to provide a mandatory interrupt-controller and '#interrupt-cells' properties. There might be optional registers memory range, "mti,reserved-cpu-vectors" and "mti,reserved-ipi-vectors" properties specified. MIPS GIC also includes a free-running global timer, per-CPU count/compare timers, and a watchdog. Since currently the GIC Timer is only supported the DT schema expects an IRQ and clock-phandler charged timer sub-node with "mti,mips-gic-timer" compatible string.

2020-07-16MIPS: Prevent READ_IMPLIES_EXEC propagationTiezhu Yang
In the MIPS architecture, we should clear the security-relevant flag READ_IMPLIES_EXEC in the function SET_PERSONALITY2() of the file arch/mips/include/asm/elf.h. Otherwise, with this flag set, PROT_READ implies PROT_EXEC for mmap to make memory executable that is not safe, because this condition allows an attacker to simply jump to and execute bytes that are considered to be just data [1]. In mm/mmap.c: unsigned long do_mmap(struct file *file, unsigned long addr, unsigned long len, unsigned long prot, unsigned long flags, vm_flags_t vm_flags, unsigned long pgoff, unsigned long *populate, struct list_head *uf) { [...] if ((prot & PROT_READ) && (current->personality & READ_IMPLIES_EXEC)) if (!(file && path_noexec(&file->f_path))) prot |= PROT_EXEC; [...] } By the way, x86 and ARM64 have done the similar thing. After commit 250c22777fe1 ("x86_64: move kernel"), in the file arch/x86/kernel/process_64.c: void set_personality_64bit(void) { [...] current->personality &= ~READ_IMPLIES_EXEC; } After commit 48f99c8ec0b2 ("arm64: Preventing READ_IMPLIES_EXEC propagation"), in the file arch/arm64/include/asm/elf.h: #define SET_PERSONALITY(ex) \ ({ \ clear_thread_flag(TIF_32BIT); \ current->personality &= ~READ_IMPLIES_EXEC; \ }) [1] https://insights.sei.cmu.edu/cert/2014/02/feeling-insecure-blame-your-parent.html Reported-by: Juxin Gao <gaojuxin@loongson.cn> Co-developed-by: Juxin Gao <gaojuxin@loongson.cn> Signed-off-by: Juxin Gao <gaojuxin@loongson.cn> Signed-off-by: Tiezhu Yang <yangtiezhu@loongson.cn> Reviewed-by: Kees Cook <keescook@chromium.org> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>

2020-06-25MIPS: io: fix sparse flood on asm/io.hAlexander Lobakin
MIPS MMIO macros for byteswapping from/to hardware endianness are a bit tricky because they use cpu_to_le{16,32,64}() in both directions. This generates a lot of questions from sparse as __le{16,32,64} types are 'restricted' and direct cast is forbidden in order to prevent messing up the byteorder. As MMIO ops are used in almost every single driver, this leads to console flooding and complicates bug hunting. We could fix it in a more proper way, i.e. separate from device / to device byteswap macros and expand __BUILD_MEMORY_*(), but this seems redundant and will produce code duplication. Instead, just expand the existing *ioswab*() macros with forced typecasting to stop floods.

2020-06-22MIPS: Loongson-2EF: disable fix-loongson3-llsc in compilerLichao Liu
Firstly, Loongson-2EF support ll/sc instructions, but doesn't need fix-loongson3-llsc compile option. Secondly, fix-loongson3-llsc will cause kernel startup fail at futex_init, because compiler will add 'sync' before 'll', which will affect __ex_table. futex_init will pass NULL uaddr parameter to futex_atomic_cmpxchg_inatomic. futex_atomic_cmpxchg_inatomic will access uaddr directly, which will cause page fault exception, the exception should be handled by __ex_table's nextinsn if the exception insn exsit in __ex_table. Because __ex_table is affected by compiler, the exception can not be handled, and futex_atomic_cmpxchg_inatomic will crash. Error code as below: __ex_table.insn = 1b, which is 'sync' compiled with fix-loongson3-llsc, but the actual exception instrction is ll. So, do_page_fault will not find the correct inst in __ex_table, and can not handle this exception.

2020-06-14Revert "btrfs: switch to iomap_dio_rw() for dio"David Sterba
This reverts commit a43a67a2d715540c1368b9501a22b0373b5874c0. This patch reverts the main part of switching direct io implementation to iomap infrastructure. There's a problem in invalidate page that couldn't be solved as regression in this development cycle. The problem occurs when buffered and direct io are mixed, and the ranges overlap. Although this is not recommended, filesystems implement measures or fallbacks to make it somehow work. In this case, fallback to buffered IO would be an option for btrfs (this already happens when direct io is done on compressed data), but the change would be needed in the iomap code, bringing new semantics to other filesystems. Another problem arises when again the buffered and direct ios are mixed, invalidation fails, then -EIO is set on the mapping and fsync will fail, though there's no real error. There have been discussions how to fix that, but revert seems to be the least intrusive option.

2020-06-13net: ethernet: ti: ale: fix allmulti for nu type aleGrygorii Strashko
On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow unregistered mcast packets to pass. This happens, because ALE VLAN entries on these SoCs do not contain port masks for reg/unreg mcast packets, but instead store indexes of ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for reg/unreg mcast packets. This path was missed by commit 9d1f6447274f ("net: ethernet: ti: ale: fix seeing unreg mcast packets with promisc and allmulti disabled"). Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti().

I'm not convinced the script makes useful automaed help lines anyway, but since we're trying to deprecate the use of "---help---" in Kconfig files, let's fix the doc example code too.
