Subject: Sec context of unix domain sockets

Hi,

how are unix domain sockets handeled regarding the default context?
Please comment on the following statement or fill my gaps:

a. Processes inherit the label of their parent, except for the init
process which gets the label of the kernel sid

b. Ext{2-4} files/directories get the label of their parent directory.
Root (/) gets its label from the file system context (fs_use) on creation.

c. Inet sockets get the label specified with the portcon statement or
the context of kernel sid (?)

d. Unix domain sockets are split in 2 parts: the socket file is treated
as b. The socket object gets the label of the kernel sid (?) Is there a
way to define the context of a unix domain socket object? The only way I
can see would be to define a transition.

Explanations and clarification much appreciated.

Martin.
