Subject: [Bug kprobes/2945] cannot probe vgettimeofday on x86_64
Date: Thu, 16 Nov 2006 20:15:00 -0000 [thread overview]
Message-ID: <20061116180734.27482.qmail@sourceware.org> (raw)
In-Reply-To: <20060720182952.2945.hunt@redhat.com>
------- Additional Comments From jkenisto at us dot ibm dot com 2006-11-16 18:07 -------
Further thoughts:
- vdso, not vtoc. (Haste and advanced age are a bad combo. :-})
- Since a kprobed instruction is copied into a kernel-space buffer and
single-stepped there, we do NOT want to allow kprobes on instructions that are
executed in user mode, such as on the vdso page.
