* [BUG] Fwd: segfault : modprobe dccp_probe/tcp_probe @ 2007-06-06 20:47 Ian McDonald 2007-06-06 22:55 ` Chuck Ebbert 0 siblings, 1 reply; 8+ messages in thread From: Ian McDonald @ 2007-06-06 20:47 UTC (permalink / raw) To: Linux Kernel Mailing List, prasanna, ananth, anil.s.keshavamurthy, David S. Miller, Patrick Andrieux, DCCP Mailing List [-- Attachment #1: Type: text/plain, Size: 7882 bytes --] Hi there, We've seen a report of a problem with dccp_probe as shown below. The user has also verified that it occurs in tcp_probe as well. This is on Dave Miller's tree but that currently tracks Linus' tree quite closely. I do note that it is around 2.6.22-rc2 timeframe so there is a possibility fixes may have gone in since.

I got it using this cmd line : #git-clone git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6.git davem Please find my .config in attachement.

It's under Kernel Hacking, Write protect kernel read only data structures. The list of commits that I see around this are at: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git&a=search&h=HEAD&st=commit&s=DEBUG_RODATA I suspect it's probably one of the latter ones giving the timing. I guess there are a couple of solutions here - either make kprobes conflict with CONFIG_DEBUG_RODATA so you can do one or the other, or look into more detail what access kprobes need.

Thanks Prasanna This patch fixes the problem of page protection introduced by CONFIG_DEBUG_RODATA. CONFIG_DEBUG_RODATA marks the text pages as read-only, hence kprobes is unable to insert breakpoints in the kernel text. This patch overrides the page protection when adding or removing a probe for the i386 architecture.
