[PATCH 0/4] libguestfs modifications in order to pass "make check"

by Laszlo Ersek

In my Fedora 34 environment, with all libguestfs features enabled except the Erlang and Haskell bindings, "make check" passes if: - these patches are applied on top of current master (f47e0bb67254), and - the btrfs-progs package is downgraded to 5.13.1-1.fc34.x86_64, according to <https://bugzilla.redhat.com/show_bug.cgi?id=2005529>. Thanks, Laszlo Laszlo Ersek (4): test-9p: fix the base directory that's exported to the guest test-md-and-lvm-devices: work around RAID0 regression in Linux v3.14/v5.4 tests: xfs: remove lazy-counter disablement test Go bindings: fix "C array of strings" -- char** -- allocation generator/actions_core.ml | 6 ---- generator/golang.ml | 46 +++++++++++++++++++++++------ tests/9p/test-9p.sh | 2 +- tests/md/test-md-and-lvm-devices.sh | 12 +++++--- 4 files changed, 46 insertions(+), 20 deletions(-) -- 2.19.1.3.g30247aa5d201

[PATCH nbdinfo v2 1/3] common/utils: Add function to convert sizes to human-readable

by Richard W.M. Jones

For example 1024 is returned as "1K". This does not attempt to handle decimals or SI units. If the number isn't some multiple of a power of 1024 then it is returned as bytes (a flag is available to indicate this). I looked at both the gnulib and qemu versions of this function. The gnulib version is not under a license which is compatible with libnbd and is also really complicated, although it does handle fractions and SI units. The qemu version is essentially just frexp + sprintf and doesn't attempt to convert to the human-readable version reversibly. --- .gitignore | 1 + common/utils/Makefile.am | 10 +++- common/utils/human-size.c | 54 +++++++++++++++++++++ common/utils/human-size.h | 49 +++++++++++++++++++ common/utils/test-human-size.c | 89 ++++++++++++++++++++++++++++++++++ 5 files changed, 201 insertions(+), 2 deletions(-) diff --git a/.gitignore b/.gitignore index 2aa1fd99..5fc59677 100644 --- a/.gitignore +++ b/.gitignore @@ -31,6 +31,7 @@ Makefile.in /bash/nbdcopy /bash/nbdfuse /bash/nbdinfo +/common/utils/test-human-size /common/utils/test-vector /compile /config.cache diff --git a/common/utils/Makefile.am b/common/utils/Makefile.am index 1ca4a370..b273ada1 100644 --- a/common/utils/Makefile.am +++ b/common/utils/Makefile.am @@ -34,6 +34,8 @@ include $(top_srcdir)/common-rules.mk noinst_LTLIBRARIES = libutils.la libutils_la_SOURCES = \ + human-size.c \ + human-size.h \ vector.c \ vector.h \ version.c \ @@ -50,8 +52,12 @@ libutils_la_LIBADD = \ # Unit tests. -TESTS = test-vector -check_PROGRAMS = test-vector +TESTS = test-human-size test-vector +check_PROGRAMS = test-human-size test-vector + +test_human_size_SOURCES = test-human-size.c human-size.c human-size.h +test_human_size_CPPFLAGS = -I$(srcdir) +test_human_size_CFLAGS = $(WARNINGS_CFLAGS) test_vector_SOURCES = test-vector.c vector.c vector.h test_vector_CPPFLAGS = -I$(srcdir) diff --git a/common/utils/human-size.c b/common/utils/human-size.c new file mode 100644 index 00000000..772f2489 --- /dev/null +++ b/common/utils/human-size.c @@ -0,0 +1,54 @@ +/* nbd client library in userspace + * Copyright (C) 2020-2021 Red Hat Inc. + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

e2fsprogs concurrency questions

by Eric Blake

TL;DR summary: is there documented best practices for parallel access to the same inode of an ext2 filesystem from multiple threads? First, a meta-question: is there a publicly archived mailing list for questions on e2fsprogs? The README merely mentions Ted's email address, and http://e2fsprogs.sourceforge.net/ is silent on contact information, although with some googling, I found at least https://patchwork.ozlabs.org/project/linux-ext4/patch/20201205045856.8953... which suggests linux-ext4(a)vger.kernel.org as a worthwhile list to mention on the web page. Now, on to my real reason for writing. The nbdkit project is using the ext2fs library to provide an ext2/3/4 filter on top of any data being served over NBD (Network Block Device protocol) in userspace: https://libguestfs.org/nbdkit-ext2-filter.1.html Searching for the word 'thread' or 'concurrent' in libext2fs.info came up with no hits, so I'm going off of minimal documentation, and mostly what I can ascertain from existing examples (of which I'm not seeing very many). Right now, the nbdkit filter forces some rather strict serialization in order to be conservatively safe: for every client that wants to connect, the nbdkit filter calls ext2fs_open(), then eventually ext2fs_file_open2(), then exposes the contents of that one extracted file over NBD one operation at a time, then closes everything back down before accepting a second client. But we'd LOVE to add some parallelization; the NBD protocol allows multiple clients, as well as out-of-order processing of requests from a single client. Right away, I already know that calling ext2fs_open() more than once on the same file system is a recipe for disaster (it is equivalent to mounting the same block device at once through more than one bare metal OS, and won't work). So I've got a proposal for how to rework the nbdkit code to open the file system exactly once and share that handle among multiple NBD clients: https://listman.redhat.com/archives/libguestfs/2021-May/msg00028.html However, in my testing, I quickly found that while it would let me visit two independent inodes at once through two separate clients, I was seeing inconsistencies when trying to visit the SAME inode through two independent clients. That is, with (abbreviated code): ext2fs_open(..., &fs); ext2fs_namei(fs, ... "/foo", &ino); ext2fs_file_open2(fs, ino, NULL, flags, &f1); // hand f1 to thread 1 ext2fs_file_open2(fs, ino, NULL, flags, &f2); // hand f2 to thread 2 // thread 1 ext2fs_file_read(f1, buf...); // thread 2 ext2fs_file_write(f2, buf...); ext2fs_file_flush(f2); // thread 1 ext2fs_file_flush(f1); ext2fs_file_read(f1, buf...); the two open file handles carried independent buffering state - even though thread 2 (tried to) flush everything, the handle f1 STILL reports the data read prior to thread 2 doing any modification. Is it okay to have two concurrent handles open to the same inode, or do I need to implement a hash map on my end so that two NBD clients requesting access to the same file within the ext2 filesystem share a single inode? If concurrent handles are supported, what mechanism can I use to ensure that a flush performed on one handle will be visible for reading from the other handle, as ext2fs_file_flush does not seem to be strong enough? Next, when using a single open ext2_ino_t, are there any concurrency restrictions that I must observe when using that handle from more than one thread at a time? For example, is it safe to have two threads both in the middle of a call to ext2_file_read() on that same handle, or must I add my own mutex locking to ensure that a second thread doesn't read data until the first thread is complete with its call? Or put another way, are the ext2fs_* calls re-entrant? Next, the nbdkit ext2 filter is using a custom io handler for converting client requests as filtered through ext2fs back into raw read/write/flush calls to pass to the real underlying NBD storage. Among others, I implemented the io_flush(io_channel) callback, but in debugging it, I see it only gets invoked during ext2fs_close(), and not during ext2fs_file_flush(). Is this a symptom of me not calling ext2fs_flush2() at points where I want to be sure actions on a single file within the filesystem are flushed to persistant storage? Finally, I see with https://patchwork.ozlabs.org/project/linux-ext4/patch/20201205045856.8953... that you recently added EXT2_FLAG_THREADS, as well as CHANNEL_FLAGS_THREADS. I think it should be fairly straightforward to tweak my nbdkit custom IO manager to advertise CHANNEL_FLAGS_THREADS (as the NBD protocol really DOES support parallel outstanding IO requests), and then add EXT2_FLAG_THREADS into the flags I pss to ext2fs_file_open2(), to try and get ext2fs to take advantage of parallel access to the underlying storage (regardless of whether the clients are parallel coming into ext2fs). Are there any concurrency issues I should be aware of on that front when updating my code? Obviously, when the kernel accesses an ext2/3/4 file system, it DOES support full concurrency (separate user space processes can open independent handles to the same file, and the processes must coordinate with well-timed fsync() or similar any time there is an expectation of a happens-before relation where actions from one process must be observed from another). But nbdkit is all about accessing the data of an ext2 filesystem from userspace, without any kernel bio involvement, and is thus reliant on whatever concurrency guarantees the ext2progs library has (or lacks). -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3266 Virtualization: qemu.org | libvirt.org
