-Subject: ARM: 9170/1: fix panic when kasan and kprobe are enabled
-
-From: sparkhuang <huangshaobo6@huawei.com>
-
-commit 8b59b0a53c840921b625378f137e88adfa87647e upstream.
-
-arm32 uses software to simulate the instruction replaced
-by kprobe. some instructions may be simulated by constructing
-assembly functions. therefore, before executing instruction
-simulation, it is necessary to construct assembly function
-execution environment in C language through binding registers.
-after kasan is enabled, the register binding relationship will
-be destroyed, resulting in instruction simulation errors and
-causing kernel panic.
-
-the kprobe emulate instruction function is distributed in three
-files: actions-common.c actions-arm.c actions-thumb.c, so disable
-KASAN when compiling these files.
-
-for example, use kprobe insert on cap_capable+20 after kasan
-enabled, the cap_capable assembly code is as follows:
-<cap_capable>:

-e2859014       add     r9, r5, #20
-......
-The emulate_ldr assembly code after enabling kasan is as follows:

-Subject: ARM: 9170/1: fix panic when kasan and kprobe are enabled
-
-From: sparkhuang <huangshaobo6@huawei.com>
-
-commit 8b59b0a53c840921b625378f137e88adfa87647e upstream.
-
-arm32 uses software to simulate the instruction replaced
-by kprobe. some instructions may be simulated by constructing
-assembly functions. therefore, before executing instruction
-simulation, it is necessary to construct assembly function
-execution environment in C language through binding registers.
-after kasan is enabled, the register binding relationship will
-be destroyed, resulting in instruction simulation errors and
-causing kernel panic.
-
-the kprobe emulate instruction function is distributed in three
-files: actions-common.c actions-arm.c actions-thumb.c, so disable
-KASAN when compiling these files.
-
-for example, use kprobe insert on cap_capable+20 after kasan
-enabled, the cap_capable assembly code is as follows:
-<cap_capable>:
-e92d47f0       push    {r4, r5, r6, r7, r8, r9, sl, lr}
-e1a05000       mov     r5, r0

-e2859014       add     r9, r5, #20
-......
-The emulate_ldr assembly code after enabling kasan is as follows:
-c06f1384 <emulate_ldr>:

-Subject: ARM: 9170/1: fix panic when kasan and kprobe are enabled
-
-From: sparkhuang <huangshaobo6@huawei.com>
-
-commit 8b59b0a53c840921b625378f137e88adfa87647e upstream.
-
-arm32 uses software to simulate the instruction replaced
-by kprobe. some instructions may be simulated by constructing
-assembly functions. therefore, before executing instruction
-simulation, it is necessary to construct assembly function
-execution environment in C language through binding registers.
-after kasan is enabled, the register binding relationship will
-be destroyed, resulting in instruction simulation errors and
-causing kernel panic.
-
-the kprobe emulate instruction function is distributed in three
-files: actions-common.c actions-arm.c actions-thumb.c, so disable
-KASAN when compiling these files.
-
-for example, use kprobe insert on cap_capable+20 after kasan
-enabled, the cap_capable assembly code is as follows:
-<cap_capable>:
-e92d47f0       push    {r4, r5, r6, r7, r8, r9, sl, lr}
-e1a05000       mov     r5, r0
-e280006c       add     r0, r0, #108    ; 0x6c
-e1a04001       mov     r4, r1
-e1a06002       mov     r6, r2
-e59fa090       ldr     sl, [pc, #144]  ;
-ebfc7bf8       bl      c03aa4b4 <__asan_load4>
-e595706c       ldr     r7, [r5, #108]  ; 0x6c
-e2859014       add     r9, r5, #20
-......
-The emulate_ldr assembly code after enabling kasan is as follows:
-c06f1384 <emulate_ldr>:
-e92d47f0       push    {r4, r5, r6, r7, r8, r9, sl, lr}
