Hi, Recently built a v5.9-rc2 kernel, it boots fine, but unable to load any kernel module. After some debugging, it shows that it's due to RWX check failure: load_module: start module_enforce_rwx_sections: index=22 sh_flags=0x7 shf_wx=0x5 layout_and_allocate: module enforce rwx sections load_module: failed to alloc layout and allocate load_module: end Futhermore, it's unable to disable the RWX check through "make menuconfig", since the ARCH_OPTIONAL_KERNEL_RWX is no for arm64. The offending section 22 looks like this: (the kernel reports 38 sectors, while we only have 37, thus near-by sections are also shown here). 20 .data 00000aa0 0000000000000000 0000000000000000 00086d08 2**3 CONTENTS, ALLOC, LOAD, RELOC, DATA 21 __bug_table 000000cc 0000000000000000 0000000000000000 000877a8 2**2 CONTENTS, ALLOC, LOAD, RELOC, DATA 22 __dyndbg 0000b9b8 0000000000000000 0000000000000000 00087878 2**3 CONTENTS, ALLOC, LOAD, RELOC, DATA 23 .data.unlikely 00000012 0000000000000000 0000000000000000 00093230 2**0 CONTENTS, ALLOC, LOAD, DATA I'm using GCC 10.2.0, could this be the cause? Thanks, Qu
