Date: Fri, 16 Jan 2015 10:27:11 +0800 From: Bryton Lee <brytonlee01@...il.com> To: netdev@...r.kernel.org, stephen@...workplumber.org Cc: Bryton Lee <brytonlee01@...il.com> Subject: Re: [PATCH iproute2] update obsolete fields in slabstat_ids[] Hi Stephen: This is the first time I submit a patch to iproute2, I forgot CC to a iproute2's maintainer. It's my fault. Could you please review my patch? :) this patch can help some old system get TCP info correctly. such as Red Hat 5u7, although is not perfect. ss searching tcp_bind_bucket and request_sock_TCP in /proc/slabinfo will fail on current upstream kernel, because on current upstream kernel slab tcp_bind_bucket and request_sock_TCP have merged into kmalloc-xx when they are creating. so in /proc/slabinfo we cannot see them any more. I have submitted other patch to mm subsystem to prevent such merging, but it still not accepted. (Yep, finally, I know my patch has problem, it doesn't make any sense, but may be we should still think about how to prevent slab merging in slab layer. ) On Mon, Dec 29, 2014 at 8:16 PM, Bryton Lee <brytonlee01@...il.com> wrote: > From: Bryton Lee <brytonlee01@...il.com> > Date: Mon, 29 Dec 2014 19:56:23 +0800 > Subject: [PATCH] tcp_open_request and tcp_tw_bucket are obsolete in current > stable kernel version, replace by request_sock_TCP and tw_sock_TCP > > Signed-off-by: Bryton Lee <brytonlee01@...il.com> > --- > misc/ss.c | 4 ++-- > 1 file changed, 2 insertions(+), 2 deletions(-) > > diff --git a/misc/ss.c b/misc/ss.c > index f0c7b34..24d58c7 100644 > --- a/misc/ss.c > +++ b/misc/ss.c > @@ -506,8 +506,8 @@ static const char *slabstat_ids[] = > { > "sock", > "tcp_bind_bucket", > - "tcp_tw_bucket", > - "tcp_open_request", > + "tw_sock_TCP", > + "request_sock_TCP", > "skbuff_head_cache", > }; > > -- > 2.0.5 > > -- > Best Regards > > Bryton.Lee > -- Best Regards Bryton.Lee -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
