No, they're not. They occur on m_copym, m_copypacket, and m_split. In practice, these are called seperately in the down and up path, and this isn't a problem (in the up path, SPLNET runs at the call to splx(), and in the down-path, the objects that are the target of the operations are/should_be locked). This sounds like a Netgraph related problem associated with the use of a kernel thread. All three of these operations can result in an allocation, and the allocation requires that the operation that calss it set splimp (comments in the same file). If this is a threaded case (e.g. -current, not 4.5/4.6 or earlier), then you would probably be saved by some of the work that Jeffrey Hsu and John Mini have done recently. For 4.5 and 4.6, it really should not be a problem (I think). -- Terry > > On Mon, 3 Jun 2002, Archie Cobbs wrote: > > > This is a question about M_EXT mbuf reference counts in FreeBSD-stable. > > > > There are several instances in kern/uipc_mbuf.c that add a reference > > to an M_EXT mbuf by either incrementing the entry in the mclrefcnt[] > > array or invoking the "custom" ext_ref routine. > > > > However, it seems that these instances are all broken because they > > don't wrap these operations within splimp()... > > > > Isn't the following C statement *not* atomic? > > > > mclrefcnt[mtocl(m->m_ext.ext_buf)]++; > > > > And isn't access to mclrefcnt[] supposed to be protected by splimp()? > > Note: MCLFREE() *does* set splimp() before decrementing M_EXT ref counts. > > > > Therefore, isn't there a race condition wrt. the M_EXT reference counts? > > > > The functions which fail to set splimp() before adding a reference are: > > > > m_copym() > > m_copypacket() > > m_split() > > > > Thanks for any comments/clarification on this subject.. > > > > -Archie > > > > __________________________________________________________________________ > > Archie Cobbs * Packet Design * http://www.packetdesign.com > > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > > with "unsubscribe freebsd-net" in the body of the message > > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-smp" in the body of the message To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message From owner-freebsd-smp Mon Jun 3 15:48: 6 2002 Delivered-To: freebsd-smp@freebsd.org Received: from scaup.mail.pas.earthlink.net (scaup.mail.pas.earthlink.net [207.217.120.49]) by hub.freebsd.org (Postfix) with ESMTP id 23A9837B403; Mon, 3 Jun 2002 15:48:03 -0700 (PDT) Received: from pool0111.cvx22-bradley.dialup.earthlink.net ([209.179.198.111] helo=mindspring.com) by scaup.prod.itd.earthlink.net with esmtp (Exim 3.33 #2) id 17F0cJ-0004dn-00; Mon, 03 Jun 2002 15:47:59 -0700 Message-ID: <3CFBF1FD.4DF1AED6@mindspring.com> Date: Mon, 03 Jun 2002 15:47:25 -0700 From: Terry Lambert X-Mailer: Mozilla 4.7 [en]C-CCK-MCD {Sony} (Win98; U) X-Accept-Language: en MIME-Version: 1.0 To: Alfred Perlstein Cc: Julian Elischer , Archie Cobbs , freebsd-net@freebsd.org, smp@freebsd.org Subject: Re: Race condition with M_EXT ref count?

Yeah, about two years ago when I was doing this the RAID controllers used Adaptec 7xxx's, which weren't supported (the developer didn't have any hardware). At $15,000 AU a card, we couldn't donate one... They should work now though.

They are a mixture of Adaptec and AMI chipsets. They all seem to work fine now. We have PERC2/QC, 2/SC, 3/SI and 2/DI (I think) all in production now. We run SMP on a 2300 and on 6300s with few problems. The only apparently SMP related problem we had was with Vinum. The plexes were not setup correctly and this seemed to trigger a fault with vinum that only appeared with SMP enabled. I disabled SMP on that box and it was stable for 12 months or so until we moved the disks to an IBM Shark. The 2300 is running SMP and vinum with correctly setup plexes with no problems. Carl.
