This case changes the type of the A_MDEV file system attribute from an unsigned 16 bit value to an unsigned 32 bit value. This is a correction. The previous type did not match the type of the attribute's source. That source is the st_dev field retrievable with stat(2). This case seeks Minor binding, which is the same as the binding for PSARC 2007/315 "Extensible Attribute Interfaces" which first introduced the attribute. Since there are no current consumers of the A_MDEV attribute, I feel this case qualifies for self review. If anyone disagrees, let me know and I'll promote it to a fast track.

Name of Document Author/Supplier: Author: Rich Morris 1.3 Date of This Document: 04 December, 2007 4. Technical Description PSARC 2007/315 (Extensible Attribute Interfaces) was approved on 13 June, 2007, and introduced a set of optional system-level file attributes. The A_MDEV attribute was one of the system attributes. This attribute represents the mounted file system device which is an unsigned 32 bit value returned by the stat(2) system call in st_dev. This value was included in the SUNWattr_ro extended attribute file for completeness. However, the value of A_MDEV returned by fgetattr(3c) is incorrect and does not match the value of st_dev returned by stat(2). Changing the type of A_MDEV from from uint16_t to uint32_t will fix this problem. With this change, fgetattr(3c) will return the same value for A_MDEC as stat(2) returns in st_dev. The changes originally approved by PSARC 2007/315 (Extensible Attribute Interfaces) were putback into Solaris Nevada on 25 October 2007.

I think it probably would still qualify for self-review, but will go ahead and start it as a normal fast-track, to allow for any further comment. I am sponsoring this case on behalf of Rich Morris. This case removes the A_MDEV file system attribute from the set of attributes returned from fgetattr(3c). The mounted file system device that this attribute is returning is available from stat(2) in st_dev. This case seeks Minor binding, which is the same as the binding for PSARC 2007/315 "Extensible Attribute Interfaces" which first introduced the attribute.

Name of Document Author/Supplier: Author: Rich Morris 1.3 Date of This Document: 6 December, 2007 4. Technical Description PSARC 2007/315 (Extensible Attribute Interfaces) was approved on 13 June, 2007, and introduced a set of optional system-level file attributes. The A_MDEV attribute is one of the system attributes. This attribute represents the mounted file system device which is also returned by the stat(2) system call in st_dev. This value was included in the SUNWattr_ro extended attribute file for completeness. However, the mount device is a 32 bit value on a 32 bit system and a 64 bit value on 64 bit system. fgetattr(3c) could be extended to provide both A_MDEV32 and A_MDEV64 attrs in the returned nvlist. However, this would require support for 32 bit applications to convert a 32 bit dev_t to and from a 64 bit dev_t. Also, for an NFS remote file, fgetattr(3c) will not return the mount device of the NFS mount, but of the file system on the server. That is not the same value returned by stat(2) in st_dev. Therefore, A_MDEV will be removed from SUNWattr_ro and will not be returned by fgetattr(3c). Applications should continue to obtain the mount device using stat(2). The changes originally approved by PSARC 2007/315 (Extensible Attribute Interfaces) were putback into Solaris Nevada on 25 October 2007. Section 4.1.1 of PSARC 2007/315 shows 2 attributes in XATTR_VIEW_READONLY: View Attribute Data type XATTR_VIEW_READONLY A_FSID uint64_t A_MDEV uint16_t A_AV_SCANSTAMP was added to XATTR_VIEW_READONLY by PSARC/2007/118 and A_OPAQUE was added to this view by PSARC/2007/476. This case removes A_MDEV so XATTR_VIEW_READONLY now has 3 attributes: View Attribute Data type XATTR_VIEW_READONLY A_FSID uint64_t A_AV_SCANSTAMP uint8_array[] A_OPAQUE boolean_value 6.
