Then copyin would write a 64 bit integer wor= th of data into the buffer. By changing g_malloc()'s len argument to be a size_t (matching malloc) the buffer will always be large enough for copyin. It is still possible to hang the process while waiting for a large enough allocation, so the M_NOWAIT flag has replaced the M_WAITOK flag. --=20 You are receiving this mail because: You are the assignee for the bug.= From owner-freebsd-geom@freebsd.org Tue Jul 19 01:50:44 2016 Return-Path: Delivered-To: freebsd-geom@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:1900:2254:206a::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id 0EBB1B9D21A for ; Tue, 19 Jul 2016 01:50:44 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org (kenobi.freebsd.org [IPv6:2001:1900:2254:206a::16:76]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client did not present a certificate) by mx1.freebsd.org (Postfix) with ESMTPS id EFF2B171B for ; Tue, 19 Jul 2016 01:50:43 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from bugs.freebsd.org ([127.0.1.118]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id u6J1ohNm073172 for ; Tue, 19 Jul 2016 01:50:43 GMT (envelope-from bugzilla-noreply@freebsd.org) From: bugzilla-noreply@freebsd.org To: freebsd-geom@FreeBSD.org Subject: [Bug 211028] [GEOM][Hyper-V] gpart can't detect the new free space after the disk capacity changes Date: Tue, 19 Jul 2016 01:50:44 +0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: Base System X-Bugzilla-Component: kern X-Bugzilla-Version: CURRENT X-Bugzilla-Keywords: X-Bugzilla-Severity: Affects Some People X-Bugzilla-Who: decui@microsoft.com X-Bugzilla-Status: New X-Bugzilla-Resolution: X-Bugzilla-Priority: --- X-Bugzilla-Assigned-To: freebsd-bugs@FreeBSD.org X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: https://bugs.freebsd.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-BeenThere: freebsd-geom@freebsd.org X-Mailman-Version: 2.1.22 Precedence: list List-Id: GEOM-specific discussions and implementations List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 19 Jul 2016 01:50:44 -0000 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D211028 --- Comment #20 from Dexuan Cui --- (In reply to Dexuan Cui from comment #19) The 11-beta3 build will begin on July 22.

I can't find a maximum parameter count or a maximum parameter size in the documentation though. I don't think I'm familiar enough with the system to come up with a value. On the other hand, if root issues a malicious ioctl() then root's process j= ust waits(using M_WAITOK). This doesn't seem like much of a concern. Lacking a sufficient hard limit, would it be best to simply change the `siz= e` parameter's type to size_t?
