xattr support for NetBSD #1332

enkore · 2016-07-14T20:17:33Z

NetBSD has a compatibility layer to Linux' xattr API: https://ftp.netbsd.org/pub/NetBSD/NetBSD-current/src/sys/sys/xattr.h (w/ no access to the system namespace, whatever that's used for)

/*
 * Support for file system extended attributes.
 *
 * This provides an interface that is compatible with Linux's extended
 * attribute support.  These calls operate on the same extended attributes
 * as <sys/extattr.h>, but access only the "user" namespace.
 */

The native mechanism is sys/extattr.h - this then also allows access to the system namespace.

Edit: In fact, it seems that NetBSD's extattr API is identical to FreeBSD's. So this might just be a matter of adding "netbsd" in xattr to the platform check.

Note: OpenBSD has neither ACLs nor xattrs.

The text was updated successfully, but these errors were encountered:

Can't get it to work, neither do the command line utilities (listextattr(1) etc). Everything's a EOPNOTSUP, independent of file system (FFS, UDF, ext2fs). Looking at the kernel code and config it should work with at least FFS and UDF (after initattr etc)

If someone uses NetBSD and Borg, feel free to test it whether it actually works (db6ce48)

src/borg/xattr.py:

elif sys.platform.startswith(('freebsd', 'netbsd')):

"whether it actually works" <-- (if you run the tests and the one test in src/borg/testsuite/xattr passes and is not skipped - then it works)

ThomasWaldmann · 2023-04-03T01:09:46Z

https://mail-index.netbsd.org/tech-kern/2022/05/24/msg028105.html

Looks like we have to wait for netbsd 10.

Hmm, guess like the xattr stuff is already in the pre-release netbsd 10 code (and also the fs corruption issues seem to be solved), so if someone has time, that could be worked on.

After getting that to work on netbsd 10 pre, behaviour of the new code should be also tested on netbsd < 10 again, so it works there as expected (== without supporting xattrs, but not crashing or malfunctioning).

ThomasWaldmann · 2023-12-24T01:56:03Z

NetBSD 10 is released:

https://www.netbsd.org/

Vagrant machine - is netbsd 10 already available?:

https://app.vagrantup.com/boxes/search?architecture=amd64&provider=virtualbox&q=netbsd&sort=created

ThomasWaldmann · 2024-04-22T12:39:35Z

Still no vagrant box, no netbsd user caring for this. Guess I'll remove it from milestone.

vmlemon · 2024-10-21T21:47:18Z

Thinking of trying to test this, on NetBSD 10, and only just noticed, that extended attributes aren't enabled, out-of-the-box, according to https://wiki.netbsd.org/tutorials/acls_and_extended_attributes_on_ffs/, on FFS volumes. It might also be interesting, to see how the latest version of the ZFS implementation behaves.

ThomasWaldmann · 2024-10-21T22:18:28Z

Yeah, please try it! If you want to work on the borg code and have questions, either ask here or on #borgbackup on liberachat IRC.

vmlemon · 2024-10-22T23:10:56Z

Seems that the official public/final release of NetBSD 10, for x86-64 is a total trainwreck, in terms of actually being able to reliably install it, on a VMware Workstation, or QEMU VM, without configuration files being missing, the root file system being corrupted, random number generator seeds not being created, or some other weird, and wonderful issue arising.

However, if I install a Daily build (uname -a says NetBSD demohost.localdomain 10.99.12 NetBSD 10.99.12 (GENERIC) #0: Tue Oct 22 00:23:42 UTC 2024 mkrepro@mkrepro.NetBSD.org:/usr/src/sys/arch/amd64/compile/GENERIC amd64), and do modload compat_linux, and pkgin install suse_base, I can try to run the Linux binaries of BorgBackup 1.4.0:

Obviously, the Linux ABI compatibility later is not a faithful, 100%-compatible clone of the "real" Linux ABI, and doesn't represent the behaviour of the native NetBSD ABI surface, but until I get around to actually building a native version of Borg, it could be useful, for some testing...

vmlemon · 2024-10-22T23:20:33Z

Seems that I can at least create a repository, using the NetBSD compatibility layer, and add a file to it, after adding an extended attribute, in the "user" namespace:

demohost# setextattr user TestAttribute "The attribute contents" TestFile
demohost# getextattr

Doesn't look like the extended attribute is actually accessed, when I look at the contents of BSDTest/data/0/, with "strings":

demohost# ls BSDTest/data/0/

For what it's worth, the version of TAR shipped with NetBSD 10 stores the attributes in a seemingly Linux-compatible way, when called with tar --xattrs --acls:

30 mtime=1729638943.560194053
70 LIBARCHIVE.xattr.user.TestAttribute=VGhlIGF0dHJpYnV0ZSBjb250ZW50cw
58 SCHILY.xattr.user.TestAttribute=The attribute contents

The pax implementation defaults to ustar, and it doesn't seem to be possible, to have it include ACLs/xattrs in an archive.

Attaching a GZip'd copy of the TAR archive, for testing TAR imports, in the future - NetBSD-Attributes.tar.gz

I don't claim massive amounts of expertise with the internals of NetBSD, or Borg itself, but from comparing system call traces, from dtruss "borg create BSDTest::3 TestFile", and dtruss "tar --xattrs --acls -cvf Test5.tar TestFile", it appears that Borg never even tries to call __acl_get_fd(), extattr_list_fd(), or extattr_get_fd(), when reading a file.

tar seems to do this, when it requests an ACL/xattr, for reading:

Unsure if it's down to a compilation-time issue, missing headers/libraries, or something else, right now...

@vmlemon IIRC we have install docs for NetBSD and there is also the Vagrantfile which contains the required commands to set the system up so borg can be built / installed.

Can you please compare the steps you needed with our install docs / Vagrantfile?

If there is "nothing new", then please remove all the console logs about your unsuccessful first tries from this issue. If you found differences, please file a separate documentation issue and then also remove the console log from this issue. This issue is NOT about installing borg on NetBSD, but about xattr support for NetBSD.

borg needs a code change to do xattrs on NetBSD, see the first few comments in this issue.

After doing that code change:

have some files with xattrs
run borg create to create an archive with these files
run borg extract to extract that archive
do the extracted files have the expected xattrs?

Also, guess we don't want to test NetBSDs Linux ABI, but rather run borg natively and check whether it works correctly on NetBSD.

vmlemon · 2024-10-23T19:44:29Z

Annoyingly, dtruss can't see inside a Linux ABI-flavoured process, beyond the return call, so I can't look into why it fails to handle xattrs, there.

vmlemon · 2024-10-23T19:48:53Z

Thanks, @ThomasWaldmann. I wasn't sure if the change was already in one of the latest releases of Borg, but I'll go through, and tidy things up.

ThomasWaldmann · 2024-10-23T19:51:55Z

As you use borg 1.4.0, this is the relevant code:

https://github.com/borgbackup/borg/blob/1.4-maint/src/borg/platform/__init__.py

Guess there could be some is_netbsd flag and that would activate the same code as is_freebsd?

https://github.com/borgbackup/borg/blob/1.4-maint/setup.py#L195

This is then needed on netbsd also.

We have automated tests for xattrs. Have a look so they get run on netbsd also.
