問題点の説明:
PHKL_36767:
(SR:8606444703 CR:JAGag02244)
ディレクトリの作成時には、親ディレクトリのデフォルトのACLエントリが新
たなサブディレクトリに2度追加されます。最初に追加されるのは、その非デ
フォルトのACLエントリで、2度目に追加されるのは、サブディレクトリのデフ
ォルトのACLエントリです。VxFSバージョン5のファイルシステムでは、最大
1024個のACLがサポートされます。ところが、最大サポートACLエントリ数を決
定するロジックに誤りがあったため、親ディレクトリのデフォルトのACL数が8
を超えると、mkdirがENOSPCで異常終了していました。
解決方法:
ACL数の正しい上限値を使用するようにコードを修正しました。

PHKL_36767:
( SR:8606444703 CR:JAGag02244 )
mkdir(1) returns ENOSPC when parent directory has more than
8 default ACLs. The following error is seen when attempting
to create a directory "dir".
"mkdir: cannot create dir: No space left on device"
Defect Description:
PHKL_36767:
( SR:8606444703 CR:JAGag02244 )
When a directory is created, the parent directory's
default ACL entries are added to the new subdirectory twice,
first as its non-default ACL entries, and second as the
subdirectory's default ACL entries. On a VxFS version 5
filesystem upto 1024 ACLs are supported. However,
due to a logic error in determining the maximum number of
ACL entries supported, mkdir fails with ENOSPC when the
parent directory has more than 8 default ACLs.
Resolution:
The code has been fixed to use the correct limit on the
number of ACLs.
Enhancement:
No
