Subject: Re: [Bug 220083] New: [REGRESSION, BISECTED] x86 ASM changes make
dispatch_hid_bpf_output_report access not-present page
Switching to mail.
Hi Benjamin,
take a look at the below pls.
The RIP points to:
22: 48 c1 e6 04 shl $0x4,%rsi
26: 48 03 77 08 add 0x8(%rdi),%rsi
2a:* 65 48 ff 46 08 incq %gs:0x8(%rsi) <-- trapping instruction
2f: c3 ret
which really is a %gs-based access and the reporter has bisected this to
9d7de2aa8b41 ("x86/percpu/64: Use relative percpu offsets")
which looks related.
My silly guess would be some bpf program does per-cpu accesses but it doesn't
know about this change so it tramples over registers. I mean, my fix would be
to disable BPF but you young kids love to play with that...
:-)
Thx.
