Hello All,
This is the version 7 of the changes to allow pquota and gquota to be used
together.
Patchset applies cleanly on top of 56cea2d088811b8cf7d2893e29bcf369a912de69
in xfs git tree.
Ran latest xfstests against it.
Changes from version 6 to version 7:
- Made all the changes suggested by Dave Chinner
- Added padding to fs_quota_stat, which made the new
data structure field ordering different from the old data
structure field ordering. So, copied the old version
to be _v1 version and used that if old version of data
structure was provided from user space.
Version 6 can be found at:
http://oss.sgi.com/archives/xfs/2012-07/msg00286.html
Changes from version 5 to version 6:
- Use radix tree instead of hash table
Version 5 can be found at:
http://oss.sgi.com/archives/xfs/2012-03/msg00310.html
Changes fron version 4 to version 5:
rebase with the current tree one simple change.
Version 4 can be found at
http://oss.sgi.com/archives/xfs/2012-02/msg00528.html
Changes from version 3 to version 4:
- Remove save_flags with storing the value (in to superblock)
based on field type info
- fix checkpatch.pl warnings and errors
Version 3 of the posting can be found at
http://oss.sgi.com/archives/xfs/2012-01/msg00309.html
Changes from version 2 to version 3:
- hash table for pquota is added.
- changes to apply cleanly with the latest tree
version 2 of the posting can be found at
http://oss.sgi.com/archives/xfs/2011-10/msg00470.html
Changes from version 1 to version 2:
- Created a new prep patch to accomodate some generic changes that ease
the later patches.
- Created a new patch to add a new field qs_pquota to fs_quota_stat
with appropriate versioning changes
- Changed the logic to allow XFS_OQUOTA.* flags to be allowed only in
the older versions.
- Changed couple of places where PQUOTA checking was on the else if
construct so as to allow both GQUOTA and PQUOTA in those places.
- Fixed comments in xfs_quota.h to reflect the current changes.
- Changed the name of the macro XFS_SB_VERSION2_SEPER_PQUOTA to
XFS_SB_VERSION2_NO_OQUOTA
- got rid of the macros XFS_MOUNT_QUOTA_SET1 and XFS_MOUNT_QUOTA_SET2
- added a new inline function xfs_inode_dquot(ip, type) to simplify
the error path in xfs_qm_dqget()
- got rid of the macro XFS_IS_THIS_QUOTA_OFF
- added comment to explain why sb_qflags is saved and restored in
xfs_sb_to_disk()

Remove all incore use of XFS_OQUOTA_ENFD and XFS_OQUOTA_CHKD.
Start using XFS_GQUOTA_.* XFS_PQUOTA_.* counterparts for GQUOTA and
PQUOTA respectively.
No changes are made to the on-disk version of the superblock yet. On-disk
copy still uses XFS_OQUOTA_ENFD and XFS_OQUOTA_CHKD.
Read and write of the superblock does the conversion from *OQUOTA*
to *[PG]QUOTA* and vice versa.

* [PATCH v7 2/5] xfs: Add pquota fields and use them at appropriate places
2013-03-21 21:52 [PATCH v7 0/5] xfs: Allow pquota and gquota to be used together Chandra Seetharaman
2013-03-21 21:52 ` [PATCH v7 1/5] xfs: Remove incore use of XFS_OQUOTA_ENFD and XFS_OQUOTA_CHKD Chandra Seetharaman

2013-03-21 21:52 ` [PATCH v7 3/5] xfs: Add pquotaino to on-disk super block Chandra Seetharaman
` (3 subsequent siblings)
5 siblings, 0 replies; 11+ messages in thread
From: Chandra Seetharaman @ 2013-03-21 21:52 UTC (permalink / raw)
To: xfs; +Cc: Chandra Seetharaman
Add project quota changes to all the places where group quota field
is used:
* add separate project quota members into various structures
* split project quota and group quotas so that instead of overriding
the group quota members incore, the new project quota members are
used instead.
* get rid of usage of the OQUOTA flag incore, in favor of separate group
and project quota flags.
* add a project dquot argument to various functions.
No externally visible interfaces changed and no superblock changes yet.

From: Chandra Seetharaman @ 2013-03-21 21:52 UTC (permalink / raw)
To: xfs; +Cc: Chandra Seetharaman
Add a new field to the superblock to add support for seperate pquota
with a specific version.
Define a macro to identify superblock with the new pquotino.
Keep backward compatibilty by allowing mount of older superblock
with no separate pquota inode.

Add proper versioning support for fs_quota_stat.
Added appropriate pads and code for backward compatibility.
Copied over the old version as it is different from the newer padded
version.
New callers of the system call have to just set the version of the data
structure being passed, and kernel will fill as much data as requested.

As an information point - I've got a separate pquota inode in the
version 5 superblock format used in the CRC patchset. Given that
this functionailty requires mkfs/db/repair support, woul dit be
better to wait until the CRC code goes in and we can then add this
feature without having to rework the superblock CRC patches around
it?
i.e. it will always be available on v5 superblocks, or v4
superblocks when the feature bit is set to indicate the pquota inode
part of the superblock is valid?
Cheers,
Dave.

Sure. I will look at your CRC patchset and see what changes are needed
to mine.
Meantime, you can answer my dilemma with the change in fs_quota_stat
(see patch 4).
As per your suggestion, I changed the data structure, to include pads at
relevant places in the data structure, which also means that the new
modified structure is not compatible with older user space code.
So, I created a copy of the older structure (fs_quota_stat_v1) and used
that if the user space request has older structure. So, now the new
kernel code is backward compatible with the old (already running) user
space code. All is well till now....
Now, I make the changes to the user space code so as to use the new
fs_quota_stat. Since the data structure has changed, the new user space
code will not work with the old kernel code.
This is where I have the dilemma.
1. Leave the user space code to work only with the newer version,
breaking the compatibility with the older kernel (with an error
message).
or
2. Read the superblock, and if pquotino is _not_ present conclude older
version of fs_quota_stat would suffice for getting quota information
from kernel (note that this will work properly with newer kernel code
too), and use the older version of fs_quota_stat_v1 for quotactl.
or
3. Any other clever way ? :)
Regards,
Chandra

The issue that the userspace code has to handle is that old kernels
decide the version of the structure, not userspace. i.e. the
version number is an output parameter, not an input parameter. Hence
on old kernels we have to detect the version after the call rather
than assume the kernel treated the version as an input...

Because the version is only an output field for old kernels, the
userspace code should be able to handle it like this:
struct fs_quota_stat fqs;
ASSERT(sizeof(struct fs_quota_stat) >= sizeof(struct fs_quota_stat_v1));
memset(&fqs, 0, sizeof(fqs));
fqs.version = FS_QSTAT_VERSION_2;
error = quotactl(...., &fqs);
if (fqs.version == FS_QSTAT_VERSION) {
struct fs_quota_stat_v1 *fqsv1 = &fqs;
/* process as version 1 */
.....
return error;
}
/* process as version 2 */
.....
return error;
However, with the version field in the same place for both
structures, userspace can read the version number after the call and
determine the correct structure type for the information returned by
the kernel...
Cheers,
Dave.
