Subject: [LSF/MM/BPF TOPIC] multi uprobe link
Date: Fri, 24 Feb 2023 11:25:17 +0100	[thread overview]
Message-ID: <Y/iQjSidojkAkNxj@krava> (raw)

We have a usecase to monitor potentially many uprobes and current way of
attaching many uprobes through perf takes long time. It's because there's
extra perf event install/schedule for each uprobe you want to attach.

It'd be great to have a another way to attach multiple uprobes probably by
adding new uprobe_multi link, that would create system wide uprobes directly
and attach bpf program to it.

Although that would not solve all the performance issues with uprobes, it
seems like a good start to solve attach/detach times.

I'd be interested in other people's experiences with uprobes and ideas on
speeding it up. The uprobe_multi link prototype should be done by that time,
hopefully ;-)

thanks,
jirka
