quota: autoload the quota_v2 module for QFMT_VFS_V1 quota format

2013-01-25T04:24:56Z

Otherwise, ext4 file systems with the quota featured enable will get a very confusing "No such process" error message if the quota code is built as a module and the quota_v2 module has not been loaded.

userns: Convert struct dquot dq_id to be a struct kqid

2012-09-18T08:01:41Z

Change struct dquot dq_id to a struct kqid and remove the now unecessary dq_type. Make minimal changes to dquot, quota_tree, quota_v1, quota_v2, ext3, ext4, and ocfs2 to deal with the change in quota structures and signatures. The ocfs2 changes are larger than most because of the extensive tracing throughout the ocfs2 quota code that prints out dq_id. quota_tree.c:get_index is modified to take a struct kqid instead of a qid_t because all of it's callers pass in dquot->dq_id and it allows me to introduce only a single conversion. The rest of the changes are either just replacing dq_type with dq_id.type, adding conversions to deal with the change in type and occassionally adding qid_eq to allow quota id comparisons in a user namespace safe way.

userns: Convert quota netlink aka quota_send_warning

2012-09-18T08:01:40Z

Modify quota_send_warning to take struct kqid instead a type and identifier pair. When sending netlink broadcasts always convert uids and quota identifiers into the intial user namespace. There is as yet no way to send a netlink broadcast message with different contents to receivers in different namespaces, so for the time being just map all of the identifiers into the initial user namespace which preserves the current behavior. Change the callers of quota_send_warning in gfs2, xfs and dquot to generate a struct kqid to pass to quota send warning. When all of the user namespaces convesions are complete a struct kqid values will be availbe without need for conversion, but a conversion is needed now to avoid needing to convert everything at once.

userns: Convert qutoactl

2012-09-18T08:01:39Z

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.

userns: Implement struct kqid

2012-09-18T08:01:38Z

Add the data type struct kqid which holds the kernel internal form of the owning identifier of a quota. struct kqid is a replacement for the implicit union of uid, gid and project id stored in an unsigned int and the quota type field that is was used in the quota data structures. Making the data type explicit allows the kuid_t and kgid_t type safety to propogate more thoroughly through the code, revealing more places where uid/gid conversions need be made. Along with the data type struct kqid comes the helper functions qid_eq, qid_lt, from_kqid, from_kqid_munged, qid_valid, make_kqid, make_kqid_invalid, make_kqid_uid, make_kqid_gid.

quota: Split dquot_quota_sync() to writeback and cache flushing part

2012-07-22T19:58:19Z

Split off part of dquot_quota_sync() which writes dquots into a quota file to a separate function. In the next patch we will use the function from filesystems and we do not want to abuse ->quota_sync quotactl callback more than necessary.

quota: Pass information that quota is stored in system file to userspace

Quota tools need to know whether quota is stored in a system file or in classical aquota.{user|group} files. So pass this information as a flag in GETINFO quotactl. Signed-off-by: Jan Kara

quota: Remove unused declaration

There is no point in declaring quotactl() syscall prototype in kernel header and 'make headers_check' complains about it. So just remove those lines. Signed-off-by: Jan Kara
