2023-10-10arm: Remove now superfluous sentinel elem from ctl_table arraysJoel Granados1-2/+2
This commit comes at the tail end of a greater effort to remove the empty elements at the end of the ctl_table arrays (sentinels) which will reduce the overall build time size of the kernel and run time memory bloat by ~64 bytes per sentinel (further information Link : https://lore.kernel.org/all/ZO5Yx5JFogGi%2FcBo@bombadil.infradead.org/) Removed the sentinel as well as the explicit size from ctl_isa_vars. The size is redundant as the initialization sets it. Changed insn_emulation->sysctl from a 2 element array of struct ctl_table to a simple struct. This has no consequence for the sysctl registration as it is forwarded as a pointer. Removed sentinel from sve_defatul_vl_table, sme_default_vl_table, tagged_addr_sysctl_table and armv8_pmu_sysctl_table. This removal is safe because register_sysctl_sz and register_sysctl use the array size in addition to checking for the sentinel.

2023-10-06arch: Reserve map_shadow_stack() syscall number for all architecturesSohil Mehta1-0/+1
commit c35559f94ebc ("x86/shstk: Introduce map_shadow_stack syscall") recently added support for map_shadow_stack() but it is limited to x86 only for now. There is a possibility that other architectures (namely, arm64 and RISC-V), that are implementing equivalent support for shadow stacks, might need to add support for it. Independent of that, reserving arch-specific syscall numbers in the syscall tables of all architectures is good practice and would help avoid future conflicts. map_shadow_stack() is marked as a conditional syscall in sys_ni.c. Adding it to the syscall tables of other architectures is harmless and would return ENOSYS when exercised. Note, map_shadow_stack() was assigned #453 during the merge process since #452 was taken by fchmodat2(). For Powerpc, map it to sys_ni_syscall() as is the norm for Powerpc syscall tables. For Alpha, map_shadow_stack() takes up #563 as Alpha still diverges from the common syscall numbering system in the other architectures.

2023-10-05ARM: 9324/1: fix get_user() broken with veneerMasahiro Yamada1-12/+2
The 32-bit ARM kernel stops working if the kernel grows to the point where veneers for __get_user_* are created. AAPCS32 [1] states, "Register r12 (IP) may be used by a linker as a scratch register between a routine and any subroutine it calls. It can also be used within a routine to hold intermediate values between subroutine calls." However, bl instructions buried within the inline asm are unpredictable for compilers; hence, "ip" must be added to the clobber list. This becomes critical when veneers for __get_user_* are created because veneers use the ip register since commit 02e541db0540 ("ARM: 8323/1: force linker to use PIC veneers").

2023-10-05ARM: 9322/1: Explicitly include correct DT includesRob Herring2-2/+1
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-10-05ARM: 9321/1: memset: cast the constant byte to unsigned charKursad Oney1-0/+1
memset() description in ISO/IEC 9899:1999 (and elsewhere) says: The memset function copies the value of c (converted to an unsigned char) into each of the first n characters of the object pointed to by s. The kernel's arm32 memset does not cast c to unsigned char. This results in the following code to produce erroneous output: char a[128]; memset(a, -128, sizeof(a)); This is because gcc will generally emit the following code before it calls memset() : mov r0, r7 mvn r1, #127 ; 0x7f bl 00000000 <memset> r1 ends up with 0xffffff80 before being used by memset() and the 'a' array will have -128 once in every four bytes while the other bytes will be set incorrectly to -1 like this (printing the first 8 bytes) : test_module: -128 -1 -1 -1 test_module: -1 -1 -1 -128 The change here is to 'and' r1 with 255 before it is used.

2023-10-05ARM: 9320/1: fix stack depot IRQ stack filterVincent Whitchurch1-4/+0
Place IRQ handlers such as gic_handle_irq() in the irqentry section even if FUNCTION_GRAPH_TRACER is not enabled. Without this, the stack depot's filter_irq_stacks() does not correctly filter out IRQ stacks in those configurations, which hampers deduplication and eventually leads to "Stack depot reached limit capacity" splats with KASAN. A similar fix was done for arm64 in commit f6794950f0e5ba37e3bbed ("arm64: set __exception_irq_entry with __irq_entry as a default").
