Subject: [PATCH V3 0/6] ARM64: Uprobe support added
Date: Wed, 2 Nov 2016 14:40:40 +0530 [thread overview]
Message-ID: <cover.1478068479.git.panand@redhat.com> (raw)
Changes since v2:
* arm64 specific is_trap_insn() removed. Using default implementation.
* arch_uprobe_analyze_insn() returns -ENOTSUPP for 32bit task probe.
V2 was here: https://lkml.org/lkml/2016/9/27/58
Patches have been rebased on v4.9-rc3. They have been tested with mustang
and seattle platform for following test cases.
1. Step-able instructions, like sub, ldr, add etc.
2. Simulation-able like ret, cbnz, cbz etc.
3. uretprobe
4. Reject-able instructions like sev, wfe etc.
5. trapped and abort xol path
6. probe at unaligned user address.
7. longjump test cases
aarch32 task probing is not yet supported.
Pratyush Anand (6):
arm64: kprobe: protect/rename few definitions to be reused by uprobe
arm64: kgdb_step_brk_fn: ignore other's exception
arm64: Handle TRAP_TRACE for user mode as well
arm64: Handle TRAP_BRKPT for user mode as well
arm64: introduce mm context flag to keep 32 bit task information
arm64: Add uprobe support
