quota: add new quotactl Q_GETNEXTQUOTA Q_GETNEXTQUOTA is exactly like Q_GETQUOTA, except that it will return quota information for the id equal to or greater than the id requested. In other words, if the requested id has no quota, the command will return quota information for the next higher id which does have a quota set. If no higher id has an active quota, -ESRCH is returned. This allows filesystems to do efficient iteration in kernelspace, much like extN filesystems do in userspace when asked to report all active quotas. This does require a new data structure for userspace, as the current structure does not include an ID for the returned quota information. Today, Ext4 with a hidden quota inode requires getpwent-style iterations, and for systems which have i.e. LDAP backends, this can be very slow, or even impossible if iteration is not allowed in the configuration.

Hook up ->set_info to this so that VFS quota time limits get set the same way as XFS ones.

quota: Switch ->get_dqblk() and ->set_dqblk() to use bytes as space units 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.

xfs: fix Q_XQUOTARM ioctl 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.

quota: Add a new quotactl command Q_XGETQSTATV XFS now supports three types of quotas (user, group and project). Current version of Q_XGETSTAT has support for only two types of quotas. In order to support three types of quotas, the interface, specifically struct fs_quota_stat, need to be expanded. Current version of fs_quota_stat does not allow expansion without breaking backward compatibility. So, a quotactl command and new fs_quota_stat structure need to be added. This patch adds a new command Q_XGETQSTATV to quotactl() which takes a new data structure fs_quota_statv. This new data structure provides support for future expansion and backward compatibility. Callers of the new quotactl command have to set the version of the data structure being passed, and kernel will fill as much data as requested. If the kernel does not support the user-space provided version, EINVAL will be returned. User-space can reduce the version number and call the same quotactl again.

vfs: define struct filename and have getname() return it getname() is intended to copy pathname strings from userspace into a kernel buffer. The result is just a string in kernel space. It would however be quite helpful to be able to attach some ancillary info to the string. For instance, we could attach some audit-related info to reduce the amount of audit-related processing needed. When auditing is enabled, we could also call getname() on the string more than once and not need to recopy it from userspace. This patchset converts the getname()/putname() interfaces to return a struct instead of a string. For now, the struct just tracks the string in kernel space and the original userland pointer for it. Later, we'll add other information to the struct as it becomes convenient. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

userns: Convert qutoactl 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.
