Subject: [PATCH] kernel: disable CONFIG_UPROBES
Date: Tue, 09 Jun 2020 18:51:12 +0000 [thread overview]
Message-ID: <8bfe5131-e177-13be-ad28-f7b15c0c93e9@ipfire.org> (raw)
[-- Attachment #1: Type: text/plain, Size: 3181 bytes --]
Quoted from #12433:
> Uprobes is the user-space counterpart to kprobes: they enable instrumentation
> applications (such as 'perf probe') to establish unintrusive probes in
> user-space binaries and libraries, by executing handler functions when the
> probes are hit by user-space applications.
>
> ( These probes come in the form of single-byte breakpoints, managed by the
> kernel and kept transparent to the probed application. )
IMHO this can be safely disabled, as there is little if any need to debug
userspace programs _that_ deeply on an IPFire machine.
Fixes: #12433
