Subject: [PATCH 2/2] arm64/module: set trampoline section flags regardless of
|
||||
CONFIG_DYNAMIC_FTRACE
|
||||
|
||||
In the arm64 module linker script, the section .text.ftrace_trampoline
|
||||
is specified unconditionally regardless of whether CONFIG_DYNAMIC_FTRACE
|
||||
is enabled (this is simply due to the limitation that module linker
|
||||
scripts are not preprocessed like the vmlinux one).
|
||||
|
||||
Normally, for .plt and .text.ftrace_trampoline, the section flags
|
||||
present in the module binary wouldn't matter since module_frob_arch_sections()
|
||||
would assign them manually anyway. However, the arm64 module loader only
|
||||
sets the section flags for .text.ftrace_trampoline when CONFIG_DYNAMIC_FTRACE=y.
|
||||
That's only become problematic recently due to a recent change in
|
||||
binutils-2.35, where the .text.ftrace_trampoline section (along with the
|
||||
.plt section) is now marked writable and executable (WAX).
|
||||
|
||||
We no longer allow writable and executable sections to be loaded due to
|
||||
commit 5c3a7db0c7ec ("module: Harden STRICT_MODULE_RWX"), so this is
|
||||
causing all modules linked with binutils-2.35 to be rejected under arm64.
|
||||
Drop the IS_ENABLED(CONFIG_DYNAMIC_FTRACE) check in module_frob_arch_sections()
|
||||
so that the section flags for .text.ftrace_trampoline get properly set to
|
||||
SHF_EXECINSTR|SHF_ALLOC, without SHF_WRITE.
