As I said - using "now" would be OK-ish. Using an arbitrary timestamp makes the setattr indistinguishable from a user-made setattr, so it updates ctime (because setattr performed a metadata change), which is wrong. Best would be to not set anything :) FUSE leaves the atime/mtime/ctime hand= ling on the filesystem's side, why force it? --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Tue Sep 19 20:54:44 2023 X-Original-To: fs@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4Rqv6r5XpCz4mHc9 for ; Tue, 19 Sep 2023 20:54:44 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mxrelay.nyi.freebsd.org (mxrelay.nyi.freebsd.org [IPv6:2610:1c1:1:606c::19:3]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256 client-signature RSA-PSS (4096 bits) client-digest SHA256) (Client CN "mxrelay.nyi.freebsd.org", Issuer "R3" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 4Rqv6r3RWLz3bG3 for ; Tue, 19 Sep 2023 20:54:44 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) ARC-Seal: i=1; s=dkim; d=freebsd.org; t=1695156884; a=rsa-sha256; cv=none; b=iAaUHUrurlWFMFToLcAFltIejv5BuJU1SX2hYzGUTjkf2NXaOa37/gza4VRueS7HWtcM64 9nqqhtxcm70J1nzT58nKcoZBgJsMMUwkpS16DBH2rCHpJdSQzf6F/HstIPj3Sj0jCXlBc6 GSqTfZuyvxLq+PQlaoVRFbK99FzRSJ9CjH3/UsC/Gu+PmUUM3DBgtTs3U8lLQAMcs1M9sT wgJekZic1ILatawuXOE4lYGZl+b0tpmCozdx6pf0F7pgWC6OSHIGGkRxfqgxgCYqfTQhUE ODKz7MnzJZd1W5MEtZgKOXtg7Xlbfp46fapkyAOafDZSjOjrCXbv0KiUq1dH6Q== ARC-Authentication-Results: i=1; mx1.freebsd.org; none ARC-Message-Signature: i=1; a=rsa-sha256; c=relaxed/relaxed; d=freebsd.org; s=dkim; t=1695156884; h=from:from:reply-to:subject:subject:date:date:message-id:message-id: to:to:cc:mime-version:mime-version:content-type:content-type: content-transfer-encoding:content-transfer-encoding: in-reply-to:in-reply-to:references:references; bh=n+IgEjLc/5YMkabAe1X7dNSNNTpmo7PgNVQdAU+0AV0=; b=x0H7F9BdB7KXvol4W/J9jhmQiZ73kwowfdJZke72PUOlqD1KMOFcHD6tjgUyH6+Yv9bcTy xBmd9qiHa7jqkciMCF6ErRDGb2Z7X4lq7MebpvAE9FgzQsaWhFfPTJ9hA+DRFNJSYLIyZ/ vBoeP77hVjYunUvz/3oobwVJar2lNjiS1lX4iiSKZllzNLqeMw2Cgk/+9h/glQtvqcJL3u nRRDI1uZ5UWj1odgVNwDh9Upv7T4MObhB+Mxq9cOcZ2szwIK4u5ldqAAzI0lzjhNHSNhdw j9/TadIFPGSnh8ZPb5NEnL35Flpgw7lmd0QZ5E0vfY2sDg9xrehpJFHLd+0Bkg== Received: from kenobi.freebsd.org (kenobi.freebsd.org [IPv6:2610:1c1:1:606c::50:1d]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256) (Client did not present a certificate) by mxrelay.nyi.freebsd.org (Postfix) with ESMTPS id 4Rqv6r2W9pzDC8 for ; Tue, 19 Sep 2023 20:54:44 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org ([127.0.1.5]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id 38JKsiWh008255 for ; Tue, 19 Sep 2023 20:54:44 GMT (envelope-from bugzilla-noreply@freebsd.org) Received: (from www@localhost) by kenobi.freebsd.org (8.15.2/8.15.2/Submit) id 38JKsiCZ008254 for fs@FreeBSD.org; Tue, 19 Sep 2023 20:54:44 GMT (envelope-from bugzilla-noreply@freebsd.org) X-Authentication-Warning: kenobi.freebsd.org: www set sender to bugzilla-noreply@freebsd.org using -f From: bugzilla-noreply@freebsd.org To: fs@FreeBSD.org Subject: [Bug 273942] fusefs(5): read operation changes ctime on FUSE filesystems Date: Tue, 19 Sep 2023 20:54:44 +0000 X-Bugzilla-Reason: AssignedTo X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: Base System X-Bugzilla-Component: kern X-Bugzilla-Version: 13.2-RELEASE X-Bugzilla-Keywords: X-Bugzilla-Severity: Affects Some People X-Bugzilla-Who: asomers@FreeBSD.org X-Bugzilla-Status: Open X-Bugzilla-Resolution: X-Bugzilla-Priority: --- X-Bugzilla-Assigned-To: fs@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 List-Id: Filesystems List-Archive: https://lists.freebsd.org/archives/freebsd-fs List-Help: List-Post: List-Subscribe: List-Unsubscribe: Sender: owner-freebsd-fs@freebsd.org MIME-Version: 1.0 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D273942 --- Comment #7 from Alan Somers --- When a FUSE file system uses the data cache, then the FUSE daemon cannot ha= ndle atime updates itself, because a read may be serviced by cache. In such a c= ase, the OS must issue the atime updates. If the data cache is not enabled, but atime and the attribute cache are, th= en the OS has a choice. Either it can track atime updates itself, or it can a= sk the server, which causes a new FUSE_GETATTR request after every read. That kind of defeats the purpose of the attribute cache. It seems to me that if the OS sends a FUSE_SETATTR with the valid field set= to FATTR_ATIME, then the server should not update the CTIME. Do you disagree?= =20 Fir if the atime update actually came from userland, for example from utimensat(), then the FATTR_CTIME bit will be set, too. --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Tue Sep 19 21:23:33 2023 X-Original-To: fs@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4Rqvm61CKfz4t0g3 for ; Tue, 19 Sep 2023 21:23:34 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mxrelay.nyi.freebsd.org (mxrelay.nyi.freebsd.org [IPv6:2610:1c1:1:606c::19:3]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256 client-signature RSA-PSS (4096 bits) client-digest SHA256) (Client CN "mxrelay.nyi.freebsd.org", Issuer "R3" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 4Rqvm56lRtz3dHc for ; Tue, 19 Sep 2023 21:23:33 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) ARC-Seal: i=1; s=dkim; d=freebsd.org; t=1695158613; a=rsa-sha256; cv=none; b=gOzs4Qze12PdElPOC8Nk8bBwNbBrLEfafWuj4gnpZgJAGMDvACaktJafL8O1CvudJwv55l fKDq3+QnUv5egJVDaAlZzrhKt9UUFGZvfNzk4iLNPqY3/v0V44vxHjAieojTJgR8AkYtCw T1U5QJjxMVbCZM2c8We/5beDvMOzMNdsm4mOfPyZhRAgODh37EQOTOAoVvZa70011EgUqK IEg9WbiiT2n0M4flnOWBKNVBOIg5lUsp0JdT+b86FMYKo0JgNNINGZfAW59h2lns/I4QM3 doYQwlvXo6JqoEKx0XP5CMzRvYledeMBTPipHZpR+eGgAW5uasbQV9XmkAr8Zw== ARC-Authentication-Results: i=1; mx1.freebsd.org; none ARC-Message-Signature: i=1; a=rsa-sha256; c=relaxed/relaxed; d=freebsd.org; s=dkim; t=1695158613; h=from:from:reply-to:subject:subject:date:date:message-id:message-id: to:to:cc:mime-version:mime-version:content-type:content-type: content-transfer-encoding:content-transfer-encoding: in-reply-to:in-reply-to:references:references; bh=txROLJ9+lY58wa5thL4I53kzE6ixHspxmEmbATmstn0=; b=lIx30bvdUJ8EbOaI9IoJKzbCDFozkumtgSPyadmSlQfomrWvsDdDzoNW6bR4GsLgYdA714 2I/FsCEd7VG7cKjEwrdNec6q5nw8yb0XT9Z02vhIUUJsIBk4EMaK/Hc4A7B4Fzn757Iek0 aA1CKV+t/5uTsidNx7sXpbMbQjt7N/qTdn0lfllI1X6fLz3OKCxgQDrSTYxObSIxW+D+AQ V/AWpghhn/tsn1QBvPX01SBP6gPos2dke9mVeOU+Ht2siyEX0MitaIfvhZhfnT+JZVpEvb RdeN4+FZyaUfJuKn+sA6nvSMwwqyqTsHMQk+Jq6zDHV1MWhzpHOuGrJbRUSbcA== Received: from kenobi.freebsd.org (kenobi.freebsd.org [IPv6:2610:1c1:1:606c::50:1d]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256) (Client did not present a certificate) by mxrelay.nyi.freebsd.org (Postfix) with ESMTPS id 4Rqvm55pknzVFM for ; Tue, 19 Sep 2023 21:23:33 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org ([127.0.1.5]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id 38JLNXkc050700 for ; Tue, 19 Sep 2023 21:23:33 GMT (envelope-from bugzilla-noreply@freebsd.org) Received: (from www@localhost) by kenobi.freebsd.org (8.15.2/8.15.2/Submit) id 38JLNXED050699 for fs@FreeBSD.org; Tue, 19 Sep 2023 21:23:33 GMT (envelope-from bugzilla-noreply@freebsd.org) X-Authentication-Warning: kenobi.freebsd.org: www set sender to bugzilla-noreply@freebsd.org using -f From: bugzilla-noreply@freebsd.org To: fs@FreeBSD.org Subject: [Bug 273942] fusefs(5): read operation changes ctime on FUSE filesystems Date: Tue, 19 Sep 2023 21:23:33 +0000 X-Bugzilla-Reason: AssignedTo X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: Base System X-Bugzilla-Component: kern X-Bugzilla-Version: 13.2-RELEASE X-Bugzilla-Keywords: X-Bugzilla-Severity: Affects Some People X-Bugzilla-Who: jfc@mit.edu X-Bugzilla-Status: Open X-Bugzilla-Resolution: X-Bugzilla-Priority: --- X-Bugzilla-Assigned-To: fs@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 List-Id: Filesystems List-Archive: https://lists.freebsd.org/archives/freebsd-fs List-Help: List-Post: List-Subscribe: List-Unsubscribe: Sender: owner-freebsd-fs@freebsd.org MIME-Version: 1.0 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D273942 --- Comment #8 from John F. Carr --- (In reply to Alan Somers from comment #7) It is apparently the responsibility of each VFS implementation to update ct= ime in response to a utimes() call. In devfs_setattr there is a call to vfs_timestamp. In ufs_setattr there is an invocation of UFS_INODE_SET_FLAG= . I don't see anything in fuse_vnop_setattr() that would update ctime when a program calls utimes(). Is there a spec saying whether it is or is not the responsibility of the fusefs server program to do it? --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Tue Sep 19 21:50:49 2023 X-Original-To: fs@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4RqwMY2jVjz4t2gv for ; Tue, 19 Sep 2023 21:50:49 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mxrelay.nyi.freebsd.org (mxrelay.nyi.freebsd.org [IPv6:2610:1c1:1:606c::19:3]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256 client-signature RSA-PSS (4096 bits) client-digest SHA256) (Client CN "mxrelay.nyi.freebsd.org", Issuer "R3" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 4RqwMY1N9yz3gtM for ; Tue, 19 Sep 2023 21:50:49 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) ARC-Seal: i=1; s=dkim; d=freebsd.org; t=1695160249; a=rsa-sha256; cv=none; b=Jo8pH1AZP5Jvp8TdESee99mWhs6xJ7oJU8EEajy54J/Sc8puuqar67hGzn8YWdueg3V+GJ DV2eXbvz597P8Xg9+cm3R06zFVbBaDOP5eo3W5iqJCMhM2GLKUPDANFdsYXQr35vP5DIj3 tUZa+CLVnY1hIIIwrcjXRMav7E/kiA81FfnUXMw9ZIx7aIziq4LmY6wsWSd6i9om2h/5c8 lWo2DwFoEpnAX+4rRgzl9Elu4MNG14yu+CvNwJ6/bv5KkHDNrJ4xtg3m6pJ1EKqhTMnlOg IztjkGyh9xyBsrkfPu5aXdnZE+Om5ICbw/4HdRcZbMMfViTxSPG33G6Kr1A7Nw== ARC-Authentication-Results: i=1; mx1.freebsd.org; none ARC-Message-Signature: i=1; a=rsa-sha256; c=relaxed/relaxed; d=freebsd.org; s=dkim; t=1695160249; h=from:from:reply-to:subject:subject:date:date:message-id:message-id: to:to:cc:mime-version:mime-version:content-type:content-type: content-transfer-encoding:content-transfer-encoding: in-reply-to:in-reply-to:references:references; bh=gij1ANYK5/4Ijgrsngc7EZROolD+e+Zml7HD/5DvevI=; b=yZOScS4W6UmS2gRKXwKe7h6xq2SwyCR4qyl/fwLR1IgjL5Qjgg3k7YsMCuTKDqmmiR6Oy4 cDcWpdW5P9xThVkEZeQ6+zYOdxgt+o9mr4jf27VgWap1F3oC8D4a0kt3JxKui4Twrigqhy OHJ7pq76mLNIhLM/I9YyBUN73eGsusNsedrwXpdia9iMvf1Kfm6sv6m0gFhHuO6Lsl5w5U sLxqrFNlki/QbiBKAmSySU9bBOK16a/0B2tQC9QP2QzkmA4YCgAT6Ezhqe8/eSmkwd1VNG Lo02h+fWg9iYMurZG1mwUHzbg8BFIgO4pvg7g1Zg7d9hu3YC/pM7SEQopaVNIA== Received: from kenobi.freebsd.org (kenobi.freebsd.org [IPv6:2610:1c1:1:606c::50:1d]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256) (Client did not present a certificate) by mxrelay.nyi.freebsd.org (Postfix) with ESMTPS id 4RqwMY0TKhzDTN for ; Tue, 19 Sep 2023 21:50:49 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org ([127.0.1.5]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id 38JLonIF082489 for ; Tue, 19 Sep 2023 21:50:49 GMT (envelope-from bugzilla-noreply@freebsd.org) Received: (from www@localhost) by kenobi.freebsd.org (8.15.2/8.15.2/Submit) id 38JLonnS082488 for fs@FreeBSD.org; Tue, 19 Sep 2023 21:50:49 GMT (envelope-from bugzilla-noreply@freebsd.org) X-Authentication-Warning: kenobi.freebsd.org: www set sender to bugzilla-noreply@freebsd.org using -f From: bugzilla-noreply@freebsd.org To: fs@FreeBSD.org Subject: [Bug 273942] fusefs(5): read operation changes ctime on FUSE filesystems Date: Tue, 19 Sep 2023 21:50:49 +0000 X-Bugzilla-Reason: AssignedTo X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: Base System X-Bugzilla-Component: kern X-Bugzilla-Version: 13.2-RELEASE X-Bugzilla-Keywords: X-Bugzilla-Severity: Affects Some People X-Bugzilla-Who: asomers@FreeBSD.org X-Bugzilla-Status: Open X-Bugzilla-Resolution: X-Bugzilla-Priority: --- X-Bugzilla-Assigned-To: fs@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 List-Id: Filesystems List-Archive: https://lists.freebsd.org/archives/freebsd-fs List-Help: List-Post: List-Subscribe: List-Unsubscribe: Sender: owner-freebsd-fs@freebsd.org MIME-Version: 1.0 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D273942 --- Comment #9 from Alan Somers --- (In reply to John F.

The MooseFS fuse server does not set ctime in response to a setattr requ= est that does not explicitly include ctime.

No. I guess I have a different definition of "file" (unless you meant "filedesc"?). I cannot see how a "range is defined for sockets or named pipes or...". It currently checks for a f_vnode, which probably is not enough. (I haven't figured out what path_fileops are, so I do not know if they work?) I can see how it can be implemented for shared memory objects. However, this is going to take a fair amount of work, since they do not use vnodes. I think it goes something like this: - Create a new fileops (f_copy_file_range), since it needs to use the correct range lock variables (in shmfd instead of vnode ones). - Move most of kern_copy_file_range() into vnodeop_copy_file_range() and call f_copy_file_range() from kern_copy_file_range(). - Create a shm_copy_file_range() that does the correct range locking and then copies via uiomove(). This would be a KABI change, so I do not think it could be MFC'd. I think there is a need for copy_file_range(2) to return EOPNOTSUP for cases it will never handle. (I need to test AF_LOCAL sockets, since I think they have vnodes?) rick From nobody Wed Sep 20 23:21:46 2023 X-Original-To: freebsd-fs@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4RrZLJ5xz6z4vKRL for ; Wed, 20 Sep 2023 23:22:00 +0000 (UTC) (envelope-from rick.macklem@gmail.com) Received: from mail-pf1-x42d.google.com (mail-pf1-x42d.google.com [IPv6:2607:f8b0:4864:20::42d]) (using TLSv1.3 with cipher TLS_AES_128_GCM_SHA256 (128/128 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256 client-signature RSA-PSS (2048 bits) client-digest SHA256) (Client CN "smtp.gmail.com", Issuer "GTS CA 1D4" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 4RrZLJ1SkQz4c9l; Wed, 20 Sep 2023 23:22:00 +0000 (UTC) (envelope-from rick.macklem@gmail.com) Authentication-Results: mx1.freebsd.org; dkim=pass header.d=gmail.com header.s=20230601 header.b=GRkbv0Bl; spf=pass (mx1.freebsd.org: domain of rick.macklem@gmail.com designates 2607:f8b0:4864:20::42d as permitted sender) smtp.mailfrom=rick.macklem@gmail.com; dmarc=pass (policy=none) header.from=gmail.com Received: by mail-pf1-x42d.google.com with SMTP id d2e1a72fcca58-68fb98745c1so260108b3a.1; Wed, 20 Sep 2023 16:22:00 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20230601; t=1695252118; x=1695856918; darn=freebsd.org; h=content-transfer-encoding:cc:to:subject:message-id:date:from :in-reply-to:references:mime-version:from:to:cc:subject:date :message-id:reply-to; bh=cUGd+OSV4/eowR4qXbHGJ1UFZTYmf3A0kdoyNY3U2+M=; b=GRkbv0BliZl4NVvwTukgzonkZTaVfMwwJRfIXa3yW1mrQzdM9V23BV2/uF1Kxs6t0/ nvHWacQ9h2Y7BVjWuDh9HsObOVlaVuPkb5s7qFEMiw1Y49pGR786WbDQRWc6WJ84YqGV o26xlzc7xyuNPltb/VKvXahvKXqbPnH/Tm6hhpts7neBSBRTgsV7BdeMrkdRsxWNgbpL rQGADiGJ14bXiok3rcpcivgwf/5/fX49PfhxTaEIJuNuLLR1CX55etuHp2u1yVwslsXy f5d/Ug0VDu4/ERiG97+444r8Xsi14/xnUrIX2tYmjUoKATfcSVOgUvoc5AfhPpw6xF3M p4Cw== X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20230601; t=1695252118; x=1695856918; h=content-transfer-encoding:cc:to:subject:message-id:date:from :in-reply-to:references:mime-version:x-gm-message-state:from:to:cc :subject:date:message-id:reply-to; bh=cUGd+OSV4/eowR4qXbHGJ1UFZTYmf3A0kdoyNY3U2+M=; b=sdCaL13BOjKXo9SeMd6iYIBhWA6iT7gNL6rt1dvCqk8DNrLTqxmWEuI2ZsoWym0fSX 9N9BTeE1lGGEWte5tVRCkN7gTgMO7KBaI8VmKNxv3HIYRw2gL5pKZXGeTAZfSYX4X4OX paAfoyTXU2MM0Gevp78oP8VnF1QONhRJm3bewN8VF7jnwLe/XY3zliT9byU831P+y3+r UXWdqF1KNfEgFtmVW8w/LvgHzVzX3VEKc5QRP/qQQcr3nVoogEX2M4MT4CJOW5mgKqk8 bdYRtOQIRgIVPUFAMyvKjKYJ+qGS0P62IlxcgiAQ48buGKeL6WmOfgJi/z0K7WQeKNFS 8InA== X-Gm-Message-State: AOJu0Yzhs/9IWd7xhCoFOEKFDdpR1ZxfUdIxLGrq8hWVmkSjRjH3kHov BQBBSvQq1eTpmZ6AXhYkaKdrsxt8pf91w/TRQbQ2n3I= X-Google-Smtp-Source: AGHT+IFtmcWrcVZcOeq4P3a6Oooba3i0UCYD5/hAPz+P+VFthRmmEx14I22xKXPPibXjKjp9WCUMKyYHxwE8+hkeUgA= X-Received: by 2002:a05:6a20:160c:b0:136:ea0e:d23 with SMTP id l12-20020a056a20160c00b00136ea0e0d23mr4974894pzj.11.1695252117716; Wed, 20 Sep 2023 16:21:57 -0700 (PDT) List-Id: Filesystems List-Archive: https://lists.freebsd.org/archives/freebsd-fs List-Help: List-Post: List-Subscribe: List-Unsubscribe: Sender: owner-freebsd-fs@freebsd.org MIME-Version: 1.0 References: In-Reply-To: From: Rick Macklem Date: Wed, 20 Sep 2023 16:21:46 -0700 Message-ID: Subject: Re: RFC: Should copy_file_range(2) work for shared memory objects?

EOPNOTSUPP (since Linux 5.19) The filesystem does not support this o= peration. EXDEV (since Linux 5.19) The files referred to by fd_in and fd_out are not on the same filesystem, and the source and target filesystems are not of the same type, or do not support cross-filesystem copy. According to the FreeBSD man page The copy_file_range() system call is expected to be compatible with th= e Linux system call of the same name.

Btw, if copy_file_range(2) starts returning anything other than EINVAL for inappropriate file descriptors, cp(1) and maybe cat(1) will need to be fixed. (cp checks for EINVAL and cat checks for EINVAL and EBADF, to decide if a non-copy_file_range(2) should be done when copy_file-range(2= ) fails.) rick From nobody Thu Sep 21 00:39:05 2023 X-Original-To: freebsd-fs@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4Rrc3V4csyz4vNvY for ; Thu, 21 Sep 2023 00:39:18 +0000 (UTC) (envelope-from rick.macklem@gmail.com) Received: from mail-pj1-x102a.google.com (mail-pj1-x102a.google.com [IPv6:2607:f8b0:4864:20::102a]) (using TLSv1.3 with cipher TLS_AES_128_GCM_SHA256 (128/128 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256 client-signature RSA-PSS (2048 bits) client-digest SHA256) (Client CN "smtp.gmail.com", Issuer "GTS CA 1D4" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 4Rrc3T6v6vz4kG5 for ; Thu, 21 Sep 2023 00:39:17 +0000 (UTC) (envelope-from rick.macklem@gmail.com) Authentication-Results: mx1.freebsd.org; none Received: by mail-pj1-x102a.google.com with SMTP id 98e67ed59e1d1-274939681b5so241402a91.0 for ; Wed, 20 Sep 2023 17:39:17 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20230601; t=1695256756; x=1695861556; darn=freebsd.org; h=content-transfer-encoding:cc:to:subject:message-id:date:from :in-reply-to:references:mime-version:from:to:cc:subject:date :message-id:reply-to; bh=HuX1XTdJTxywbnxtkjESZdh7GrdCEvvWnFzH1gZ63Ks=; b=JC40m9tX0S2GtHca7ZVNxJPhqhAlvvj8Quvf0rStv5v2+k64udympAHEtIR8XJKUyT 160xF5VYk+4XXP1YoS1H6plsXksDGxHWI5mL7DCB1XU5ez6EUBj759ASNNuHrT99o8Ub NRsYJxwpA5NSrKfnY4P+mRIQQ2iyeVyBBxZvyG1pEXOMf7OoaxyKxgu6fgQhBE6fW16X FPpRf2tJJPIBwBaosN8KDl+dygMTolCtwGQ+KG0+ZkMEvUeWOQ/ZDzACeVkeJ65/3Nov RQyT9psYJ3H04X6DsO5X24qYW7CxQRezt2nWS3HlaijZjRqmDQ7zwbEy5qOw4jFaSU6l xfZA== X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20230601; t=1695256756; x=1695861556; h=content-transfer-encoding:cc:to:subject:message-id:date:from :in-reply-to:references:mime-version:x-gm-message-state:from:to:cc :subject:date:message-id:reply-to; bh=HuX1XTdJTxywbnxtkjESZdh7GrdCEvvWnFzH1gZ63Ks=; b=XhVXvMwZ0pVgsVPg5vQ6aZVK7vApDivSgQDxiUvmUdgeb7+MtVszhTijCDZbclL+Y0 8rY4coeIB/hBLKBFGYnXA6JPtaBnaGnzNWHAnHsG04STmXLMHbOXiHDdfHKKywG0g+zm O2cr4XnpOgJbmK85vaZWFP22g65NuJW4ckEzfl5oiNrmm4hnc0vspYZ8V2NUUaQ7cUxw KtiKz7AO41cLWCiITCzd6YO2zmtLNx1b4O/CQ/HX9+x3Pd9/D8MhrV0LahkCnav4aL8B pQNAQ/3aUQ/1oWzcBtp5+cWVp2oxAFc3LwiwiD/2k1+6mil60jhuJyHKstjP8y6I2oLB D3+g== X-Gm-Message-State: AOJu0Yy2t1ZtsWXhRyCvtBBpPiiRVwwKAdTm/tuV9XHyV2IwDqaL0AyV m+FlVQLxPcnzU8/QuvuLA6Q47rJbHCGTbaznaw== X-Google-Smtp-Source: AGHT+IFEDtCEehXhNp/gXo5IbSwrHvvz+rLxdEMU3P9qcWqiWSnGOCN9R0VfNv3hNsC6VBPNtkPioBgSEFri28NFD8o= X-Received: by 2002:a17:90b:1490:b0:268:f45:c10a with SMTP id js16-20020a17090b149000b002680f45c10amr4177256pjb.26.1695256756559; Wed, 20 Sep 2023 17:39:16 -0700 (PDT) List-Id: Filesystems List-Archive: https://lists.freebsd.org/archives/freebsd-fs List-Help: List-Post: List-Subscribe: List-Unsubscribe: Sender: owner-freebsd-fs@freebsd.org MIME-Version: 1.0 References: In-Reply-To: From: Rick Macklem Date: Wed, 20 Sep 2023 17:39:05 -0700 Message-ID: Subject: Re: RFC: Should copy_file_range(2) work for shared memory objects?

I'm fine with that, but we'll see what others say. Thanks for your comments, rick ps; When I go look at the Linux man page, I often get an out-of-dat one, so I am never sure what Linux currently does. (It is also confusing because some distros implement copy_file_range() in their libc instead of the kernel. I think more recent Linux kernels do support the syscall.)

Previously zfsd would crash in the presence of a pool with a top-level-vdev that had previously been removed. The crash happened because the configuration nvlist of such a TLV contains an empty ZPOOL_CONFIG_CHILDREN array, which led to a pop_front from an empty list, which has undefined behavior. The crash only happened in stable/14 and later, probably do to differences in libcxx, but the change should be MFCed anyway.

Previously zfsd would crash in the presence of a pool with a top-level-vdev that had previously been removed. The crash happened because the configuration nvlist of such a TLV contains an empty ZPOOL_CONFIG_CHILDREN array, which led to a pop_front from an empty list, which has undefined behavior. The crash only happened in stable/14 and later, probably do to differences in libcxx, but the change should be MFCed anyway.
