2020-07-28xfs: create xfs_dqtype_t to represent quota typesDarrick J. Wong
Create a new type (xfs_dqtype_t) to represent the type of an incore dquot (user, group, project, or none). Rename the incore dquot's dq_flags field to q_type. This allows us to replace all the "uint type" arguments to the quota functions with "xfs_dqtype_t type", to make it obvious when we're passing a quota type argument into a function.

There are there are three extents counters per inode, one for each of the forks. Two are in the legacy icdinode and one is directly in struct xfs_inode. Switch to a single counter in the xfs_ifork structure where it uses up padding at the end of the structure.

2020-01-06xfs: quota: move to time64_t interfacesArnd Bergmann
As a preparation for removing the 32-bit time_t type and all associated interfaces, change xfs to use time64_t and ktime_get_real_seconds() for the quota housekeeping. This avoids one difference between 32-bit and 64-bit kernels, raising the theoretical limit for the quota grace period to year 2106 on 32-bit instead of year 2038. Note that common user space tools using the XFS quotactl interface instead of the generic one still use the y2038 dates. To fix quotas properly, both the on-disk format and user space still need to be changed.

There are many, many xfs header files which are included but unneeded (or included twice) in the xfs code, so remove them. nb: xfs_linux.h includes about 9 headers for everyone, so those explicit includes get removed by this.

2015-01-28quota: Switch ->get_dqblk() and ->set_dqblk() to use bytes as space unitsJan Kara
Currently ->get_dqblk() and ->set_dqblk() use struct fs_disk_quota which tracks space limits and usage in 512-byte blocks. However VFS quotas track usage in bytes (as some filesystems require that) and we need to somehow pass this information. Upto now it wasn't a problem because we didn't do any unit conversion (thus VFS quota routines happily stuck number of bytes into d_bcount field of struct fd_disk_quota). Only if you tried to use Q_XGETQUOTA or Q_XSETQLIM for VFS quotas (or Q_GETQUOTA / Q_SETQUOTA for XFS quotas), you got bogus results. Hardly anyone tried this but reportedly some Samba users hit the problem in practice. So when we want interfaces compatible we need to fix this. We bite the bullet and define another quota structure used for passing information from/to ->get_dqblk()/->set_dqblk. It's somewhat sad we have to have more conversion routines in fs/quota/quota.c and another copying of quota structure slows down getting of quota information by about 2% but it seems cleaner than overloading e.g. units of d_bcount to bytes.

2014-05-05xfs: fix Q_XQUOTARM ioctlEric Sandeen
The Q_XQUOTARM quotactl was not working properly, because we weren't passing around proper flags. The xfs_fs_set_xstate() ioctl handler used the same flags for Q_XQUOTAON/OFF as well as for Q_XQUOTARM, but Q_XQUOTAON/OFF look for XFS_UQUOTA_ACCT, XFS_UQUOTA_ENFD, XFS_GQUOTA_ACCT etc, i.e. quota type + state, while Q_XQUOTARM looks only for the type of quota, i.e. XFS_DQ_USER, XFS_DQ_GROUP etc. Unfortunately these flag spaces overlap a bit, so we got semi-random results for Q_XQUOTARM; i.e. the value for XFS_DQ_USER == XFS_UQUOTA_ACCT, etc. yeargh. Add a new quotactl op vector specifically for the QUOTARM operation, since it operates with a different flag space. This has been broken more or less forever, AFAICT.

2012-09-18userns: Convert qutoactlEric W. Biederman
Update the quotactl user space interface to successfull compile with user namespaces support enabled and to hand off quota identifiers to lower layers of the kernel in struct kqid instead of type and qid pairs. The quota on function is not converted because while it takes a quota type and an id. The id is the on disk quota format to use, which is something completely different. The signature of two struct quotactl_ops methods were changed to take struct kqid argumetns get_dqblk and set_dqblk. The dquot, xfs, and ocfs2 implementations of get_dqblk and set_dqblk are minimally changed so that the code continues to work with the change in parameter type. This is the first in a series of changes to always store quota identifiers in the kernel in struct kqid and only use raw type and qid values when interacting with on disk structures or userspace. Always using struct kqid internally makes it hard to miss places that need conversion to or from the kernel internal values.
