* kexec: split kexec_load syscall from kexec core codeDave Young2015-09-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two kexec load syscalls, kexec_load another and kexec_file_load. kexec_file_load has been splited as kernel/kexec_file.c. In this patch I split kexec_load syscall code to kernel/kexec.c. And add a new kconfig option KEXEC_CORE, so we can disable kexec_load and use kexec_file_load only, or vice verse. The original requirement is from Ted Ts'o, he want kexec kernel signature being checked with CONFIG_KEXEC_VERIFY_SIG enabled. But kexec-tools use kexec_load syscall can bypass the checking. Vivek Goyal proposed to create a common kconfig option so user can compile in only one syscall for loading kexec kernel. KEXEC/KEXEC_FILE selects KEXEC_CORE so that old config files still work. Because there's general code need CONFIG_KEXEC_CORE, so I updated all the architecture Kconfig with a new option KEXEC_CORE, and let KEXEC selects KEXEC_CORE in arch Kconfig. Also updated general kernel code with to kexec_load syscall. [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: Dave Young <dyoung@redhat.com> Cc: Eric W.

This results in a moderate reduction of duplicated lines, and will prevent further duplication as the PSCI client code is updated for PSCI 1.0 and beyond. The two legacy platform users of the PSCI invocation code are updated to account for interface changes. In both cases the power state parameter (which is constant) is now generated using macros, so that the pack/unpack logic can be killed in preparation for PSCI 1.0 power state changes.

| | |_|/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Provide a software-based implementation of the priviledged no access support found in ARMv8.1. Userspace pages are mapped using a different domain number from the kernel and IO mappings. If we switch the user domain to "no access" when we enter the kernel, we can prevent the kernel from touching userspace. However, the kernel needs to be able to access userspace via the various user accessor functions. With the wrapping in the previous patch, we can temporarily enable access when the kernel needs user access, and re-disable it afterwards. This allows us to trap non-intended accesses to userspace, eg, caused by an inadvertent dereference of the LIST_POISON* values, which, with appropriate user mappings setup, can be made to succeed. This in turn can allow use-after-free bugs to be further exploited than would otherwise be possible. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

A temporary, early pte is created which is migrated to a permanent mapping in paging_init. This is also needed since the attributes may change as the memory types are initialized. The 3MiB range of fixmap spans two pte tables, but currently only one pte is created for early fixmap support. Re-add FIX_KMAP_BEGIN to the index calculation in highmem.c since the index for kmap does not start at zero anymore.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since v3.18, attempts to deliver IRQ0 are rejected, breaking orion5x. Fix this by increasing all interrupts by one, as did 5d6bed2a9c8b for dove. Also, force MULTI_IRQ_HANDLER for all orion platforms (including dove) as the specific handler is needed to shift back IRQ numbers by one. [gregory.clement@free-electrons.com]: moved the select MULTI_IRQ_HANDLER from PLAT_ORION_LEGACY to ARCH_ORION5X as it broke the build for dove.

Instead of using the -mlong-calls option (which affects all compiler emitted bl instructions, but not the ones in assembler), this patch allocates some additional space at module load time, and populates it with PLT like veneers when encountering relocations that are out of range. This should work with all relocations against symbols exported by the kernel, including those resulting from GCC generated implicit function calls for ftrace etc. The module memory size increases by about 5% on average, regardless of whether any PLT entries were actually needed. However, due to the page based rounding that occurs when allocating module memory, the average memory footprint increase is negligible.
