From: Allison Henderson <allison.henderson@oracle.com>
This patch adds two new fields to the atti/d. They are nname and
nnamelen. This will be used for parent pointer updates since a
rename operation may cause the parent pointer to update both the
name and value. So we need to carry both the new name as well as
the target name in the attri/d.

/me wonders, do we need to null out new_name and new_namelen here?
I /think/ the answer is that the current codebase doesn't care since
we're now doing XFS_DA_OP_ADDNAME, and addname looks only at
name/namelen and has no idea that new_name/new_namelen even exist?

/me starts to wonder if the two name len fields and the value len field
ought to be u8/u16 to conserve space in xfs_da_args, but that's an
optimization question for after this patchset.

I don't think it's correct to remove this check entirely -- NVREPLACE is
the only operation that uses nname/nname_len, right? Shouldn't this be:
if (op_flags != XFS_ATTRI_OP_FLAGS_NVREPLACE &&
attrp->alfi_nname_len != 0)
return false;

This change fixes a validation flaw in existing code, right?
If so, it ought to be a separate patc... you know what? 26 patches is
enough, I'll let this one slide since LARP is still experimental.

Ok, I think that makes sense, I dont think there's a path where an
NVREPLACE can be zero. Will add.

I think so, I believe this came up in one of the reviews so i added it.

Alrighty, thanks for the reviews!

Renames that generate parent pointer updates can join up to 5
inodes locked in sorted order. So we need to increase the
number of defer ops inodes and relock them in the same way.

When would we be processing *five* different inodes?
Does this happen when src_ip is a child of src_dp, target_ip is a child
of target_dp, all four inodes are distinct, and the VFS asks us to move
src_ip from src_dp to target_dp, unlink target_ip from target_dp, *and*
install a whiteout in the dirent in src_dp? In which case src_ip,
target_ip, and wip all need parent pointer adjustments?
So that's three inodes that need to stay locked for deferred operations;
what about src_dp and target_dp? I don't think they need to stay
locked, but OTOH it's probably easier (for now) to lock everything until
the end of the entire rename operation instead of making everyone
reason about when they fall off the transaction chain, right?
If the answer to all that is yes and the typo gets fixed, then

Right, the src_ip is overwriting the target_ip in another directory.

Well they need their directory entries updated, also we need the
parents to reconstruct what the old parent pointer for their children
were so that we can remove the correct one from the child ips.

It makes sense to me that they should stay locked. Will update the
typo.
Thanks for the reviews!

Could you hoist this to a static inline xfs_iunlock_after_rename
function that is adjacent to xfs_sort_for_rename, please? It's easier
to verify that it does the right thing w.r.t. multiple array references
pointing to the same incore inode when the two array management
functions are right next to each other.
static inline void
xfs_iunlock_after_rename(
struct xfs_inode **i_tab,
int num_inodes)
{
for (i = num_inodes - 1; i >= 0; i--) {
/* Skip duplicate inodes if src and target dps are the same */
if (!i_tab[i] || (i > 0 && i_tab[i] == i_tab[i - 1]))
continue;
xfs_iunlock(i_tab[i], XFS_ILOCK_EXCL);
}
}
With that cleaned up,

Tmp files are used as part of rename operations and will need attr forks
initialized for parent pointers. Expose the init_xattrs parameter to
the calling function to initialize the fork.

Whiteouts are created prior to being added to a directory, right?
If so, shouldn't this be s/init_xattrs/true/g to save time?
Everything else in here looks good though!

well, replaced with xfs_has_parent(mp) if we want to retain the non
parent code functionality. I dont know that it really saves that much
time, but we can implement it that way of folks prefer.

I didn't used to think it would make much difference, but the reason why
the init_xattrs thing got added is that Dave benchmarked file creation
on a system that has selinux enabled (and hence sets selinux security
xattrs on every file created) and discovered that it /did/ make a
difference.

Add the new parent attribute type. XFS_ATTR_PARENT is used only for parent pointer
entries; it uses reserved blocks like XFS_ATTR_ROOT.

From: allison.henderson @ 2022-09-22 5:44 UTC (permalink / raw)
To: linux-xfs
From: Allison Henderson <allison.henderson@oracle.com>
We need to define the parent pointer attribute format before we start
adding support for it into all the code that needs to use it. The EA
format we will use encodes the following information:
name={parent inode #, parent inode generation, dirent offset}
value={dirent filename}
The inode/gen gives all the information we need to reliably identify the
parent without requiring child->parent lock ordering, and allows
userspace to do pathname component level reconstruction without the
kernel ever needing to verify the parent itself as part of ioctl calls.
By using the dirent offset in the EA name, we have a method of knowing
the exact parent pointer EA we need to modify/remove in rename/unlink
without an unbound EA name search.
By keeping the dirent name in the value, we have enough information to
be able to validate and reconstruct damaged directory trees. While the
diroffset of a filename alone is not unique enough to identify the
child, the {diroffset,filename,child_inode} tuple is sufficient. That
is, if the diroffset gets reused and points to a different filename, we
can detect that from the contents of EA. If a link of the same name is
created, then we can check whether it points at the same inode as the
parent EA we current have.

Attribute names of parent pointers are not strings. So we need to modify
attr_namecheck to verify parent pointer records when the XFS_ATTR_PARENT flag is

We need to add, remove or modify parent pointer attributes during
create/link/unlink/rename operations atomically with the dirents in the
parent directories being modified. This means they need to be modified
in the same transaction as the parent directories, and so we need to add
the required space for the attribute modifications to the transaction
reservations.

Also -- even before parent pointers we could have five inodes involved
in a rename transaction, so I think this change needs to be a separate
bugfix at the start of the series. Rename isn't experimental, so I
can't let this one slide. :/

Ooh I like this refactoring of xfs_calc_rename_reservation. :)
I guess we now tr_attr{setm,rm} before computing the rename reservation
so this is ok.

Should the size of the name, newname, and value buffers be added into
overhead? They take up log space too.

Doesn't xfs_calc_rename_reservation add this to tr_rename already?

Shouldn't each of these += additions be made to
xfs_calc_{icreate,mkdir,link,symlink,remove}_reservation, respectively?

That would make sense, but we cant really calculate that ahead of time
with out just assuming the max size which is up to 64k for the value.
Maybe those sizes should be added on after we know what they are?

Oh, I think we can remove the tr_rename.tr_logres update. But not the
logcount update right?
xfs_calc_rename_reservation just calculates what tr_rename.tr_logres
should be, but it doesnt make any additions. It's that's used over in
xfs_calc_namespace_reservations, but we still need to update
tr_rename.tr_logcount which is separate field from tr_rename.tr_logres.

I suppose we could redo it that way? But then not all of the "+="
would disappear if they worked like xfs_calc_rename_reservation. Just
the *.tr_logres. Do we really want separate wrappers for just these
oneliners though?

They have to be worst case values, but fortunately we know what the
worst case is:
name: sizeof(ondisk parent ptr structure) + iovec overhead
newname: same for rename, and zero everywhere else iiuc?
value: 255 + iovec_overhead

Right, though you could update XFS_RENAME_LOG_COUNT (or turn it into a
helper function).

Yes, once those macros start acquiring logic, they ought to turn into
static inline helpers.

Hmm, updating the #define would affect non pptr code paths, and it
seems a bit small for a helper. I may leave the log count here if it
doesnt bother folks, I dont think it's out of place along with the
other logcount updates.

I meant modifying XFS_MKDIR_SPACE_RES and XFS_CREATE_SPACE_RES:
unsigned int
xfs_pptr_calc_space_res(
struct xfs_mount *mp,
unsigned int namelen)
{
/*
* Code lifted from xfs_attr_calc_size, check this for
* correctness since I assumed that a pptr never requires rmt
* blocks...
*/
return XFS_DAENTER_SPACE_RES(mp, XFS_ATTR_FORK) +
XFS_NEXTENTADD_SPACE_RES(mp, namelen, XFS_ATTR_FORK);
}
unsigned int
xfs_create_space_res(
struct xfs_mount *mp,
unsigned int namelen)
{
unsigned int ret;
ret = XFS_IALLOC_SPACE_RES(mp) + XFS_DIRENTER_SPACE_RES(mp, namelen);
if (xfs_has_parent(mp))
ret += xfs_pptr_calc_space_res(mp, namelen);
return ret;
}
unsigned int
xfs_mkdir_space_res(
struct xfs_mount *mp,
unsigned int namelen)
{
return xfs_create_space_res(mp, namelen);
}
(and then change the function case names as necessary)

The block reservations for create/mkdir/link/unlink all need to be
adjusted upwards, which will eliminate the need for the comment.

Nit: typedef usage.

Forwarding on from the v2 series --
This patch ought to be modifying XFS_LINK_SPACE_RES so that each link()
update reserves enough space to handle an expansion in the tdp directory
(as it does now) *and* an expansion in the xattr structure of the sip
child file. This is how we avoid dipping into the free space reserve
pool midway through a transaction, and avoid shutdowns when space is
tight.
tr_res == space we reserve in the *log* to record updates.
XFS_LINK_SPACE_RES == block we reserve from the filesystem free space to
handle expansions of metadata structures.
At this point in this version of the patchset, you've increased the log
space reservations in anticipation of logging more information per
transaction. However, you've not increased the free space reservations
to handle potential node splitting in the ondisk xattr btree.
(The rest of the patchset looks ok.)

Ok, looking at the later reviews, I'll add a similar helper function
here to use in place of XFS_LINK_SPACE_RES:
unsigned int
xfs_link_space_res(
struct xfs_mount *mp,
unsigned int namelen)
{
unsigned int ret;
ret = XFS_DIRENTER_SPACE_RES(mp, namelen);
if (xfs_has_parent(mp))
ret += xfs_pptr_calc_space_res(mp, namelen);
return ret;
}
Thanks!

Same comment as the last two patches: Please update
xfs_symlink_space_res to handle the free space that might be needed to
expand the xattr structure ondisk:
unsigned int
xfs_symlink_space_res(
struct xfs_mount *mp,
unsigned int namelen,
unsigned int fsblocks)
{
unsigned int ret;
ret = XFS_IALLOC_SPACE_RES(mp) +
XFS_DIRENTER_SPACE_RES(mp, namelen) +
fsblocks;
if (xfs_has_parent(mp))
ret += xfs_pptr_calc_space_res(mp, namelen);
return ret;
}
Everything else in here otherwise looks good to me.

Cross renames are handled separately from standard renames, and
need different handling to update the parent attributes correctly.

Four? I think this means that xfs_calc_rename_reservation needs to do:
overhead += 4 * (sizeof(struct xfs_attri_log_item) +
whatever_else);
Right?
The rest of the patch looks fine, though...

...if you reflowed this to do two-tab indenting instead of kernel-style
indenting I wouldn't be sad. ;)

Ok, I will bump up the overhead in xfs_calc_rename_reservation and see
if I can plumb another param through xfs_trans_alloc to add in the
additional name/value sizes

Indent variables and parameters in xfs_rename in preparation for
parent pointer modifications. White space only, no functional
changes. This will make reviewing new code easier on reviewers.

This patch removes the old parent pointer attribute during the rename
operation, and re-adds the updated parent pointer. In the case of
xfs_cross_rename, we modify the routine not to roll the transaction just
yet. We will do this after the parent pointer is added in the calling
xfs_rename function.

Same block reservation comment as most of the previous ones, except this
one is super nasty:

(The rest of the logic looks ok now.)

This patch adds a helper function xfs_attr_list_context_init used by
xfs_attr_list. This function initializes the xfs_attr_list_context
structure passed to xfs_attr_list_int. We will need this later to call
xfs_attr_list_int_ilocked when the node is already locked.

Parent pointers returned to the get_fattr tool cause errors since
the tool cannot parse parent pointers. Fix this by filtering parent
parent pointers from xfs_attr_list.

Some additional comments on this new one. I think maybe this should
have been an rfc since xfs_attr_list doesnt have any existing
filtration logic. So with out assuming what behavior people would
prefer it to have, I've applied the minimal amount of change that
solves the problem for now. Suggestions welcome though, I assumed
probably people will want to discuss other solutions during the review.
Thanks!

Yes!! Parent pointers should /never/ be accessible by the standard VFS
xattr syscalls, nor should the XFS ATTR_MULTI calls handle them.
Changes to parent pointers are performed via separate syscalls
(link/unlink/mknod/creat/etc), and I see you've created a separate
parent pointer ioctl later on for userspace to retrieve them. I think
this is the correct access model.
To check that assertion -- getxattr/setxattr/removexattr (and the ATTRMULTI
equivalents) are prevented from accessing parent pointers directly
because you'd have to be able to set XFS_ATTR_PARENT in
xfs_da_args.attr_filter, right?
And for the VFS to get/set/remove a parent pointer, XFS would have to
provide a struct xattr_handler with ->flags = XFS_ATTR_PARENT, which XFS
will never do, right?
And for ATTR_MULTI to touch a parent pointer, xfs_attr_filter (and the
ioctl api) would have to learn about XFS_ATTR_PARENT, which XFS will
also never do, right?
If the answers to these three questions are all yes then you're 95% of
the way to an RVB, except...

...wouldn't it suffice to do:
static inline bool
xfs_attr_filter_listent(
struct xfs_attr_list_context *context,
int flags)
{
return context->attr_filter != (flags & XFS_ATTR_NSP_ONDISK_MASK);

...I think this is unnecessary since none of the callers can actually
set XFS_ATTR_PARENT in the first place, right?

Well, you set XFS_IOC_ATTR_PARENT which later translates to
XFS_ATTR_PARENT. I do that later in the set, but I see you've already

I think we do have to publish that XFS_ATTR_PARENT exists, but I don't
think we have to implement the XFS_IOC_ATTR_PARENT translation

Almost.... XFS_ATTR_NSP_ONDISK_MASK includes XFS_ATTR_PARENT, so here
we'd want XFS_ATTR_NSP_ONDISK_MASK & ~XFS_ATTR_PARENT
Also, XFS_ATTR_NSP_ONDISK_MASK doesnt include XFS_ATTR_LOCAL which was
previously allowable
Hmm, how bout just:
return context->attr_filter != flags & (XFS_ATTR_ROOT |
XFS_ATTR_SECURE | XFS_ATTR_LOCAL)
I think that preserves the existing behavior

The caller can stuff any bit in there they want, but until now it
didn't matter because context->attr_filter was unused (getfattr appears
to just leave it as 0). So the existing behavior was that requesting
nothing resulted in everything. Now we're flipping that (at least
internally).
If we use the filter logic above, this would need to turn into
context->attr_filter = (XFS_ATTR_ROOT | XFS_ATTR_SECURE |
XFS_ATTR_LOCAL)

Agreed. The fewer symbols that end up in xfs_fs.h the better, because
anything we publish in there becomes a part of the userspace ABI and has
to be supported "forever".

It does, but I think it'll cause conflicts with future online fsck code.
(Let me check my understanding of the xfs_attr_list callers first:
There are /three/ namespaces, but only two of them have defined flag
bits. "root.*" and "secure.*" have XFS_ATTR_{ROOT,SECURE}, but "user.*"
is recorded by the absence of any XFS_ATTR_ flag. IOWs, attr_filter
isn't a bit mask of all the namespaces that the caller wants; it's a
cookie value to coordinate between the xfs_attr_list caller and the
supplied putent function.
vfs_listxattr doesn't allow userspace to specify an xattr namespace, so
it returns xattrs from user.*, root.*, and secure.*. xfs_vn_listxattr
doesn't set attr_filter, and xfs_xattr_put_listent doesn't check.
XFS_IOC_ATTRLIST_BY_HANDLE, on the other hand, requires userspace to
specify which namespace they want to list. That's why it's the one
caller that sets context.attr_filter, and xfs_ioc_attr_put_listent does
a comparison to filter attributes from other namespaces.
The xattr scrubber calls xfs_attr_list_ilocked to walk every xattr
attached to the file. For each call to ->put_listent, it uses the
built-in hash information to look up the attr name provided to confirm
that hashed lookups also work. For /this/ usecase, we want
xfs_attr_list_* to return all xattrs because we need to check all xattr
namespaces. Hence it doesn't set context.attr_filter, and
xchk_xattr_listent doesn't check it either.
...right?)
((Come to think of it -- shouldn't the ifork and attr leaf block
verifiers check that each attr entry struct have at most one of the
namespace bits set?))
After the addition of parent pointers, xfs_xattr_put_listent needs to
filter out (flags & XFS_ATTR_PARENT) cases. XFS_IOC_ATTRLIST_BY_HANDLE
won't need any changes if we drop the XFS_IOC_ATTR_PARENT flag, since
there won't be any way for XFS_ATTR_PARENT to be set in attr_filter.
The xattr scrubber still needs to walk every xattr to perform a complete
scan. Hence it will still not touch context.attr_filter, nor will it
want any filtering to be applied at all.
For the forthcoming totally-doesn't-exist-yet parent pointer online fsck
code, I'd sorta like to reuse that function to walk only the parent
pointers. I'm not 100% sure I will end up doing that -- the cursoring
code would be useful if I have to use a live inode scan to do the
checking and repair, but OTOH it's a little annoying to deal with the
warts of the xfs_attr_list_context. But in theory, I'd have
xchk_parent_listent or whatever the function ends up being named ignore
anything that wasn't XFS_ATTR_PARENT. This mechanism also does not want
the xfs_attr_list_* functions to perform any filtering.
In terms of APIs, xfs_attr_filter_parent doesn't really make a lot of
sense -- if you set context.attr_filter = XFS_ATTR_PARENT, you'll get
all the xattrs (including the non-parent ones), but if you set any other
value (e.g. XFS_ATTR_SECURE), you'll get all the non-parent xattrs,
including the root.* and user.* attrs. The ->put_listent function still
has to do its own filtering. Right?
What if xfs_xattr_put_listent exited early if (flags & XFS_ATTR_PARENT)
and we never define a XFS_IOC_ATTR_ROOT? Won't that suffice to prevent
the userspace xattr APIs from ever returning a parent pointer by
accident?
Looking ahead to the GETPARENTS code, I think the filtering code in
xfs_ioc_attr_put_listent would work for returning only the parent
pointers, right? Since it does set context.attr_filter to
XFS_ATTR_PARENT on its own? And you wouldn't need any of the other
changes here?

Ok, I tried this out and it seems to work, so I will add this in the
next revision. Thanks for the reviews!

To recap from the v2 thread:
Parent pointers are backwards links through the directory tree. xfsdump
already records the forward links in the dump file. xfsrestore uses
those forward links to rebuild the directory tree, which recreates the
parent pointers automatically. Hence we don't need ATTRMULTI to reveal
(or recreate) the parent pointer xattrs; the kernel does that when we
create the directory tree.
The second reason I can think of why we don't want to expose the parent
pointers through the xattr APIs is that we don't want to reveal ondisk
metadata directly to users -- some day we might want to change wthat's
stored on disk, or store them in a totally separate structure, or
whatever.
If we force the interface to be the GETPARENTS ioctl, then we've
decoupled the front and backends. I conclude that the /only/ userspace
API that should ever touch parent pointers is XFS_IOC_GETPARENTS.

We definitely don't need this in the userspace API anymore.

And now that we don't have XFS_IOC_ATTR_PARENT anymore, change this to:
memset(&context, 0, sizeof(struct xfs_attr_list_context));
error = xfs_ioc_attr_list_context_init(ip, namebuf,
namebuf_size, 0, &context);
if (error)
goto out_kfree;
context.attr_flags = XFS_ATTR_PARENT;
This way you can reuse the xfs_attr_list* infrastructure without needing
to add flags to the userspace xattr APIs or then have to filter that out
from all the incoming xattr calls.

We hold the ILOCK between the list and the attr getting, so we shouldn't
need OKNOENT here to avoid error returns, right?

We can take this out if it bothers folks, but I dont worry about this
one since the multi list ioctls actually use the filter from the user

To: linux-xfs
From: Allison Henderson <allison.henderson@oracle.com>
Dave and I were discussing some recent test regressions as a result of
me turning on nrext64=1 on realtime filesystems, when we noticed that
the minimum log size of a 32M filesystem jumped from 954 blocks to 4287
blocks.
Digging through xfs_log_calc_max_attrsetm_res, Dave noticed that @size
contains the maximum estimated amount of space needed for a local format
xattr, in bytes, but we feed this quantity to XFS_NEXTENTADD_SPACE_RES,
which requires units of blocks. This has resulted in an overestimation
of the minimum log size over the years.
We should nominally correct this, but there's a backwards compatibility
problem -- if we enable it now, the minimum log size will decrease. If
a corrected mkfs formats a filesystem with this new smaller log size, a
user will encounter mount failures on an uncorrected kernel due to the
larger minimum log size computations there.
However, the large extent counters feature is still EXPERIMENTAL, so we
can gate the correction on that feature (or any features that get added
after that) being enabled. Any filesystem with nrext64 or any of the
as-yet-undefined feature bits turned on will be rejected by old
uncorrected kernels, so this should be safe even in the upgrade case.

Er, did you change this patch much?
I was really hoping you'd *RVB* tag it and send it back out. :)

Oh, I didnt change anything, but I assumed if it's unmerged it's
supposed to have the submitters SOB? The sob is a sort of legal
signature that you certify that the contents are clear to be open src
right?
TBH, most of the patches originally came from Dave or Mark, but have
sort of evolved over the reviews and rebases. It's not really clear
who authored what anymore, but the point is that in submitting it, you
certify that no ones un-sobed code has wandered in.
At least that was my understanding?

<shrug> My understanding is that if someone sends you a patch and you
add it to your tree unchanged, you're allowed to retain the From: of the
original author and tag if RVB if you like, and since you didn't make
any changes, you don't need to add a SOB.
IOWS I /think/ you only need to add your own SOB if you're /not/ passing
it along unchanged.

Having established that we can reduce the minimum log size computation
for filesystems with parent pointers or any newer feature, we should
also drop the compat minlogsize code that we added when we reduced the
transaction reservation size for rmap and reflink.
