Wong <djwong@kernel.org> I'm having some second thoughts about the attr2 handling in this patch. xfs/186 regresses like so: --- /tmp/fstests/tests/xfs/186.out 2021-05-13 11:47:55.849859833 -0700 +++ /var/tmp/fstests/xfs/186.out.bad 2021-08-11 15:36:38.892735511 -0700 @@ -195,6 +195,7 @@ ================================= ATTR +ATTR2 forkoff = 47 u.sfdir2.hdr.count = 25 u.sfdir2.hdr.i8count = 0 AFAICT, prior to this patch, if a V4 fs did not have attr2 set in the ondisk superblock and the user did not mount with -oattr2, the fs would continue to use attr1 format. Indeed, xfs_sbversion_add_attr2 did: if ((mp->m_flags & XFS_MOUNT_ATTR2) && !(xfs_sb_version_hasattr2(&mp->m_sb))) { /* try to add feature to ondisk super */ } Now, however, we mix the two together -- if the ondisk super has attr2 set, XFS_FEAT_ATTR2 will be set, and if the mount options include -oattr2, XFS_FEAT_ATTR2 will also be set. Now that function does: if (xfs_has_attr2(mp)) return; if (xfs_has_noattr2(mp)) return; /* try to add feature to ondisk super */ The behavior is not the same here -- if neither the ondisk sb nor the mount options have attr2, we upgrade an attr1 fs to attr2. I think this is why xfs/186 has this regression. Furthermore, this breaks upgrading an attr1 filesystem to attr2 through the use of the mount option because the function that adds the feature will exit early because FEAT_ATTR2 was set by the mount option even though it's not set on disk: # mkfs.xfs -m crc=0 /dev/sda -f meta-data=/dev/sda isize=256 agcount=4, agsize=644992 blks = sectsz=512 attr=2, projid32bit=1 = crc=0 finobt=0, sparse=0, rmapbt=0 = reflink=0 bigtime=0 inobtcount=0 = metadir=0 data = bsize=4096 blocks=2579968, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0, ftype=1 log =internal log bsize=4096 blocks=2560, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 Discarding blocks...Done. # xfs_db -x -c 'version attr1' /dev/sda writing all SBs versionnum [0xb4b4+0x282] = V4,NLINK,DIRV2,ATTR,ALIGN,LOGV2,EXTFLG,MOREBITS,LAZYSBCOUNT,PROJID32BIT,FTYPE # mount /dev/sda /mnt -o attr2 # attr -s moo -V urk /mnt Attribute "moo" set to a 3 byte value for /mnt: urk # umount /mnt # xfs_db -c version /dev/sda versionnum [0xb4b4+0x282] = V4,NLINK,DIRV2,ATTR,ALIGN,LOGV2,EXTFLG,MOREBITS,LAZYSBCOUNT,PROJID32BIT,FTYPE So I think this patch needs more work. --D > > --D > > > --- > > fs/xfs/libxfs/xfs_attr.c | 4 +- > > fs/xfs/libxfs/xfs_attr_leaf.c | 36 +++++---- > > fs/xfs/libxfs/xfs_bmap.c | 4 +- > > fs/xfs/libxfs/xfs_ialloc.c | 10 +-- > > fs/xfs/scrub/scrub.c | 2 +- > > fs/xfs/xfs_acl.c | 2 +- > > fs/xfs/xfs_bmap_util.c | 2 +- > > fs/xfs/xfs_discard.c | 2 +- > > fs/xfs/xfs_export.c | 2 +- > > fs/xfs/xfs_file.c | 2 +- > > fs/xfs/xfs_filestream.h | 2 +- > > fs/xfs/xfs_icache.c | 7 +- > > fs/xfs/xfs_inode.c | 15 ++-- > > fs/xfs/xfs_inode.h | 3 +- > > fs/xfs/xfs_ioctl.c | 5 +- > > fs/xfs/xfs_iomap.c | 4 +- > > fs/xfs/xfs_iops.c | 12 +-- > > fs/xfs/xfs_log.c | 14 ++-- > > fs/xfs/xfs_log_cil.c | 4 +- > > fs/xfs/xfs_mount.c | 24 +++--- > > fs/xfs/xfs_mount.h | 26 +------ > > fs/xfs/xfs_super.c | 141 ++++++++++++++++------------------ > > fs/xfs/xfs_symlink.c | 3 +- > > 23 files changed, 149 insertions(+), 177 deletions(-) > > > > diff --git a/fs/xfs/libxfs/xfs_attr.c b/fs/xfs/libxfs/xfs_attr.c > > index 6771bd700770..f3d57ca10826 100644 > > --- a/fs/xfs/libxfs/xfs_attr.c > > +++ b/fs/xfs/libxfs/xfs_attr.c > > @@ -224,7 +224,7 @@ xfs_attr_try_sf_addname( > > if (!error && !(args->op_flags & XFS_DA_OP_NOTIME)) > > xfs_trans_ichgtime(args->trans, dp, XFS_ICHGTIME_CHG);

I think this > is why xfs/186 has this regression. Hmmm - I think I changed it to do that explicitly at one point, then didn't remove it when splitting out attr2 specific stuff. e.g. the comment now says: /* * Switch on the ATTR2 superblock bit (implies also FEATURES2) by default unless * we've explicitly been told not to use attr2 (i.e. noattr2 mount option). */ Which is how it's behaving. I'll just revert then "upgrade by default" behaviour and go back to the way it used to work. That'll also fix the other problem you mention, too. Cheers, Dave.
