But I got your E-mail address and thought "MAYBE THAT IS MY DESTINY" to find someone special? Really there was written that you wish to know me. So I don't know where you did get MY E-MAIL ADDRESS but I hope that is NOT JUST MISTAKE. I hope to hear from you soon.... If you decide to answer me I promise to SEND YOU big LETTER and MY BEST PHOTOS !!! I'd like to learn more about you.

But if the vlan is IGMPv2 only, then an initial Join from a Linux client might go out as v3 (if it hasn't seen a query yet) and be ignored. I believe this is the case that force_igmp_version really addresses. And it turns out that force_igmp_version=2 doesn't fully work. If the host sees a IGMPv3 query, it still responds with a v3 Join despite the flag.

If queries for an earlier version are present, that is the IGMP version all use, and the features of the later version are not available to anyone. +-DLS -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html From mboxrd@z Thu Jan 1 00:00:00 1970 From: David Stevens Subject: Re: Date: Mon, 27 Sep 2010 15:01:18 -0700 Message-ID: References: <20100927200500.GB25879@obsidianresearch.com> <4CA1048C.8020508@rincon.com> Mime-Version: 1.0 Content-Type: text/plain; charset="US-ASCII" Cc: Christoph Lameter , Jason Gunthorpe , "linux-rdma@vger.kernel.org" , "netdev@vger.kernel.org" , "netdev-owner@vger.kernel.org" To: Bob Arendt Return-path: Received: from e32.co.us.ibm.com ([32.97.110.150]:33874 "EHLO e32.co.us.ibm.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1750865Ab0I0WBh (ORCPT ); Mon, 27 Sep 2010 18:01:37 -0400 In-Reply-To: <4CA1048C.8020508@rincon.com> Sender: netdev-owner@vger.kernel.org List-ID: Bob Arendt wrote on 09/27/2010 01:54:36 PM: > On 09/27/10 13:23, Christoph Lameter wrote: > > On Mon, 27 Sep 2010, David Stevens wrote: > > > >> Because a querier can set the robustness value and > >> query interval to anything you want.

I believe > this is the case that force_igmp_version really addresses. Not really. It's for the case where there is no querier at all, but a snooping switch that only supports IGMPv2. After any query has put an interface in IGMPv2 mode (or IGMPv1), the initial report for all joins will use the earlier protocol. It isn't per-group, it's per interface, and you cannot mix versions of IGMP on the same network. > > And it turns out that force_igmp_version=2 doesn't fully work. > If the host sees a IGMPv3 query, it still responds with a v3 Join > despite the flag. Bug report and candidate patch here: > https://bugzilla.kernel.org/show_bug.cgi?id=18212 This is a special case. The "correct" alternative is to drop the query and not send any report at all. Sending an answer in the originating protocol doesn't hurt anything here, because MC routers are required to use the earlier version too; there should be no such thing as an "IGMPv3-only querier" as in that report. IGMPv3 compliance *requires* falling back to IGMPv2 if there is a v2 query by another router. By answering instead of dropping, it allows fuller filter information from a manual query to be returned even if the network is using v2 MC routers, but dropping and ignoring the query as required by RFC does not fix the bug & patch submitter's problem. Which is why I also NACKed that patch. +-DLS From mboxrd@z Thu Jan 1 00:00:00 1970 From: Christoph Lameter Subject: Re: Date: Tue, 28 Sep 2010 10:49:25 -0500 (CDT) Message-ID: References: <20100927200500.GB25879@obsidianresearch.com> Mime-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Cc: Jason Gunthorpe , linux-rdma@vger.kernel.org, netdev@vger.kernel.org, David Miller , Bob Arendt To: David Stevens Return-path: Received: from smtp110.prem.mail.ac4.yahoo.com ([76.13.13.93]:32307 "HELO smtp110.prem.mail.ac4.yahoo.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with SMTP id S1750941Ab0I1Pt3 (ORCPT ); Tue, 28 Sep 2010 11:49:29 -0400 In-Reply-To: Sender: netdev-owner@vger.kernel.org List-ID: On Mon, 27 Sep 2010, David Stevens wrote: > No. I'm not talking about the force_igmp_tunable here, I'm talking > about the per-interface robustness and interval settings which come from > the querier (whatever version you are using). The igmp subsystem currently does not keep state on the interface layer about robustness etc. An interval setting is only kept for IGMP v3 and used only for general query timeouts with igmp V3. The interval is different one from the one used for the host membership reports. Looking at the spec I get the impression that these variables seems to be mainly of interest to router to router communications?

Currently, fentry does not filter with !rcu_is_watching, maybe because this is an extreme corner case. Not sure whether it is worthwhile or not. Maybe if you can give a concrete example (e.g., attachment point) with current code base to show what the issue you encountered and it will make it easier to judge whether adding !rcu_is_watching() is necessary or not. > > Signed-off-by: Ze Gao > --- > kernel/trace/bpf_trace.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/kernel/trace/bpf_trace.c b/kernel/trace/bpf_trace.c > index 9a050e36dc6c..3e6ea7274765 100644 > --- a/kernel/trace/bpf_trace.c > +++ b/kernel/trace/bpf_trace.c > @@ -2622,7 +2622,7 @@ kprobe_multi_link_prog_run(struct bpf_kprobe_multi_link *link, > struct bpf_run_ctx *old_run_ctx; > int err; > > - if (unlikely(__this_cpu_inc_return(bpf_prog_active) != 1)) { > + if (unlikely(__this_cpu_inc_return(bpf_prog_active) != 1 || !rcu_is_watching())) { > err = 0; > goto out; > } From mboxrd@z Thu Jan 1 00:00:00 1970 Received: from lindbergh.monkeyblade.net (lindbergh.monkeyblade.net [23.128.96.19]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (No client certificate requested) by smtp.subspace.kernel.org (Postfix) with ESMTPS id A819FEA3; Sun, 21 May 2023 08:08:53 +0000 (UTC) Received: from mail-ed1-x52c.google.com (mail-ed1-x52c.google.com [IPv6:2a00:1450:4864:20::52c]) by lindbergh.monkeyblade.net (Postfix) with ESMTPS id 4B9D4FE; Sun, 21 May 2023 01:08:52 -0700 (PDT) Received: by mail-ed1-x52c.google.com with SMTP id 4fb4d7f45d1cf-510ea8d0bb5so4942550a12.0; Sun, 21 May 2023 01:08:52 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20221208; t=1684656531; x=1687248531; h=in-reply-to:content-disposition:mime-version:references:message-id :subject:cc:to:date:from:from:to:cc:subject:date:message-id:reply-to; bh=RPjmHku2tRjtFMFQ0VjYD/cqFGXrpt1kb3JxP1rwY4o=; b=TaAB2s+rAIf0e7ZEN0HPfsDv183v6EQEAU/OBXmfNmn1OR9LaFAVlVMktEDKn17r4+ jl0SIHvraXvVGpaf3uLE9+rfQ5P9EcqDB5wNoJAg04fsBeRXa2tN6sopZdu83A2ZZkwT nRC0oolJNF75DU6hOOkwc9GMUjGRkbLOc6E+McvJFj/cdeY2edAAzQS3q0D2Jt2Cx9C2 X3Zkd/ngS/C1/MltWiCnEs8f9qcDjqCZY1LOCFTZtfU5dBe4GsbCeTQVbN6LDueIHw8D Abo7IHCansw5Ng793aF1pBM/7dSRR9Y5uVpckZmj9joOXbU5syCkahG868Ph2cRLK/tG dMkw== X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20221208; t=1684656531; x=1687248531; h=in-reply-to:content-disposition:mime-version:references:message-id :subject:cc:to:date:from:x-gm-message-state:from:to:cc:subject:date :message-id:reply-to; bh=RPjmHku2tRjtFMFQ0VjYD/cqFGXrpt1kb3JxP1rwY4o=; b=Q/JtxsitwBy7er7t0DlZXLhN9gJOFwUrpps4kw4ivmRP7amCZhxkHv7A4r82GWMWtk SlVvOK1iZJCHGHnnqB/y0iTjfSk3vF8ZY9ACznOFYFhE6+29NgMWLtmblv59Nl5qBH56 wGvhW9sMyDyWQIy2b46dU9v4IjQJnHkZJ54q38tn6blDc/xWJko7chYsx39YiiK7wNcU Y4ptuB+/19G6pKVi/+qMCn51qujJCciYjVfEz/tXSKtYAW5CRNXBGJfjzhFXzymKHsb9 y+B+gtPfyjYytzKMO5CqeJK8rSDapid6d48Cnq7yN74Zkb5ZgKwx9Avbbr41sNIo1aV5 rX6w== X-Gm-Message-State: AC+VfDzbfFubRM8jZIr7ym0JPIlWEmzQVryhDCDPoTkXknZ4lwbrkJ7N y1VjH2XXlGbUvJzBuW6StqY= X-Google-Smtp-Source: ACHHUZ7sMC1jICnKE6CiK42E6KdCejLh/wDV4CapwptXihZa6QWWijVRU/9eOMOAdE4aHPGnb1r6Cg== X-Received: by 2002:a17:907:7f8c:b0:96a:5e38:ba49 with SMTP id qk12-20020a1709077f8c00b0096a5e38ba49mr7916436ejc.2.1684656530364; Sun, 21 May 2023 01:08:50 -0700 (PDT) Received: from krava (ip-94-113-247-30.net.vodafone.cz.

Agreed, it's rare, especially after Peter's patches which push narrow down rcu eqs regions in the idle path and reduce the chance of any traceable functions happening in between. However, from RCU's perspective, we ought to check if rcu_is_watching theoretically when there's a chance our code will run in the idle path and also we need rcu to be alive, And also we cannot simply make assumptions for any future changes in the idle path. You know, just like what was hit in the thread. > Maybe if you can give a concrete example (e.g., attachment point) > with current code base to show what the issue you encountered and > it will make it easier to judge whether adding !rcu_is_watching() > is necessary or not. I can reproduce likely warnings on v6.1.18 where arch_cpu_idle is traceable but not on the latest version so far. But as I state above, in theory we need it. So here is a gentle ping :) .

It really does return false (rather than faulting?) if the current CPU is deep within the idle loop. In addition, the recent x86/entry rework (thank you Peter and Thomas!) mean that the "idle loop" is quite restricted, as can be seen by the invocations of ct_cpuidle_enter() and ct_cpuidle_exit(). For example, in default_idle_call(), these are immediately before and after the call to arch_cpu_idle(). Would the following help? Or am I missing your point?
