Subject: Please help, I want kprobe.multi support on arm64, but regs is replaced by args
Date: Sun, 25 Jun 2023 16:27:44 +0800 [thread overview]
Message-ID: <0118f3b5-d13a-57f0-7a7f-41f59666d387@linux.dev> (raw)
Hi, Mark Rutland and other developers.
I am trying to implement the rethook of the arm64 platform, referring to
the code of other architectures, it can already run normally on the v6.1
branch, but after commit 26299b3f6ba2 ("ftrace: arm64: move from REGS to
ARGS"), regs is no longer supported, resulting in CONFIG_FPROBE is also
not supported (although RETHOOK is implemented). I try to revert the
patch, and kprobe.multi can be run correctly. Now, what should I do?
Should I roll back this patch or find a way to run fprobe without regs?
Any help is welcome.
