* userns: Convert struct dquot dq_id to be a struct kqidEric W. Biederman2012-09-181-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Modify dqget to take struct kqidEric W. Biederman2012-09-181-1/+1
| | | | | | | | | | | | | | | Modify dqget to take struct kqid instead of a type and an identifier pair. Modify the callers of dqget in ocfs2 and dquot to take generate a struct kqid so they can continue to call dqget. The conversion to create struct kqid should all be the final conversions that are needed in those code paths.

* userns: Convert quota netlink aka quota_send_warningEric W. Biederman2012-09-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | 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 qutoactlEric W. Biederman2012-09-182-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 kqidEric W. Biederman2012-09-181-0/+125
| | | | | | | | | | | | | | | | | | 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.

* userns: Add kprojid_t and associated infrastructure in projid.hEric W. Biederman2012-09-182-0/+107
| | | | | | | | | | | | | | | | | | | | | | | Implement kprojid_t a cousin of the kuid_t and kgid_t. The per user namespace mapping of project id values can be set with /proc/<pid>/projid_map. A full compliment of helpers is provided: make_kprojid, from_kprojid, from_kprojid_munged, kporjid_has_mapping, projid_valid, projid_eq, projid_eq, projid_lt. Project identifiers are part of the generic disk quota interface, although it appears only xfs implements project identifiers currently. The xfs code allows anyone who has permission to set the project identifier on a file to use any project identifier so when setting up the user namespace project identifier mappings I do not require a capability.

* userns: Convert vfs posix_acl support to use kuids and kgidsEric W. Biederman2012-09-182-1/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - In setxattr if we are setting a posix acl convert uids and gids from the current user namespace into the initial user namespace, before the xattrs are passed to the underlying filesystem. Untranslatable uids and gids are represented as -1 which posix_acl_from_xattr will represent as INVALID_UID or INVALID_GID. posix_acl_valid will fail if an acl from userspace has any INVALID_UID or INVALID_GID values. In net this guarantees that untranslatable posix acls will not be stored by filesystems. - In getxattr if we are reading a posix acl convert uids and gids from the initial user namespace into the current user namespace. Uids and gids that can not be tranlsated into the current user namespace will be represented as -1. - Replace e_id in struct posix_acl_entry with an anymouns union of e_uid and e_gid. For the short term retain the e_id field until all of the users are converted. - Don't set struct posix_acl.e_id in the cases where the acl type does not use e_id. Greatly reducing the use of ACL_UNDEFINED_ID. - Rework the ordering checks in posix_acl_valid so that I use kuid_t and kgid_t types throughout the code, and so that I don't need arithmetic on uid and gid types.

* audit: Add typespecific uid and gid comparatorsEric W. Biederman2012-09-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The audit filter code guarantees that uid are always compared with uids and gids are always compared with gids, as the comparason operations are type specific. Take advantage of this proper to define audit_uid_comparator and audit_gid_comparator which use the type safe comparasons from uidgid.h. Build on audit_uid_comparator and audit_gid_comparator and replace audit_compare_id with audit_compare_uid and audit_compare_gid. This is one of those odd cases where being type safe and duplicating code leads to simpler shorter and more concise code. Don't allow bitmask operations in uid and gid comparisons in audit_data_to_entry. Bitmask operations are already denined in audit_rule_to_entry. Convert constants in audit_rule_to_entry and audit_data_to_entry into kuids and kgids when appropriate. Convert the uid and gid field in struct audit_names to be of type kuid_t and kgid_t respectively, so that the new uid and gid comparators can be applied in a type safe manner.

| | | | | | | | | | | | | | | | | | The sending socket of an skb is already available by it's port id in the NETLINK_CB. If you want to know more like to examine the credentials on the sending socket you have to look up the sending socket by it's port id and all of the needed functions and data structures are static inside of af_netlink.c. So do the simple thing and pass the sending socket to the receivers in the NETLINK_CB. I intend to use this to get the user namespace of the sending socket in inet_diag so that I can report uids in the context of the process who opened the socket, the same way I report uids in the contect of the process who opens files.

This guarantees we don't have issues when pid wraparound occurs. Use a kuid_t in the owner field of struct ip6_flowlabel when the share type is IPV6_FL_S_USER to add user namespace support. In /proc/net/ip6_flowlabel capture the current pid namespace when opening the file and release the pid namespace when the file is closed ensuring we print the pid owner value that is meaning to the reader of the file. Similarly use from_kuid_munged to print uid values that are meaningful to the reader of the file. This requires exporting pid_nr_ns so that ipv6 can continue to built as a module.

Nothing in the helper functions is ARM specific, so I hope that other implementations can consolidate some of their code by making use of these helpers. This has been sitting in linux-next most of the merge cycle, and has been tested by several OMAP folk. I've tested it on sa11x0 platforms, and given it my best shot on my broken platforms which have the amba-pl08x controller. The last point is the addition to feature-removal-schedule.txt, which will have a merge conflict. Between myself and TI, we're planning to remove the old TI DMA implementation next year."

A FIFO underflow condition occurs when the input FIFO is completely empty and the LCDC raster controller logic that drives data to the output pins attempts to fetch data from the FIFO. When a FIFO underflow condition occurs, incorrect data will be driven out on the LCDC data pins. Software should poll the FUF bit field in the LCD_STAT register to check if an error condition has occurred or service the interrupt if FUF_EN is enabled when FUF occurs. If the FUF bit field has been set to 1, this will indicate an underflow condition has occurred and then the software should execute a reset of the LCDC via the LPSC. This problem may occur if the LCDC FIFO threshold size (LCDDMA_CTRL[TH_FIFO_READY]) is left at its default value after reset. Increasing the FIFO threshold size will reduce or eliminate underflows. Setting the threshold size to 256 double words or larger is recommended.

This information is completely internal to DSS as logic levels for the above signals hold no meaning on the DSI bus. Hence a DSI panel driver should be totally oblivious of these fields. Fix the logic levels/polarities in the DISPC and DSI registers to a default value. This is done by overriding these fields in omap_video_timings struct filled by the panel driver for DISPC, and use the equivalent default values when programming DSI_CTRL registers. Also, remove the redundant polarity related fields in omap_dss_dsi_videomode_data. Signed-off-by: Archit Taneja <archit@ti.com>

The fields are: - Hsync logic level - Vsync logic level - Data driven on rising/falling edge of pixel clock - Output enable/Data enable logic level - HSYNC/VSYNC driven on rising/falling edge of pixel clock Out of these parameters, Hsync and Vsync logic levels are a part of the timings in the Xorg modeline configuration. So it makes sense to move the to omap_video_timings. The rest aren't a part of modeline, but it still makes sense to move these since they are related to panel timings. These fields stored in omap_panel_config in dssdev are configured for LCD panels, and the corresponding LCD managers in the DISPC_POL_FREQo registers. Add the above fields in omap_video_timings. Represent their state via new enums. Add these parameters to the omap_video_timings instances in the panel drivers. Keep the corresponding IVS, IHS, IPC, IEO, RF and ONOFF flags in omap_panel_config for now. The struct will be removed later. Signed-off-by: Archit Taneja <archit@ti.com>
