I think the libc.so is shared between processes, because it is a shared library and OS is engaged for saving memory.
But, below, the maps of bash, shows r-xp and r--p rw-p attributes to libc.so which mean private memory space.
Can anybody explain this for me?

ypfiles - Yellow Pages data base and directory structure
Description
The Yellow Pages (YP) data base lookup service uses a data base of files in the directory hierarchy. A data base consists of two files,
created by calls to the library package. One has the filename extension and the other has the filename extension For instance, the data
base named is implemented by the pair of files and
A data base served by YP is called a YP map. A YP domain is a named set of YP maps. Each YP domain is implemented as a subdirectory of
containing the maps. The number of YP domains that can exist is unlimited. Each domain can contain any number of maps.
The YP maps are not required by the YP lookup service, although they may be required for the normal operation of other parts of the system.
The YP lookup service serves all maps. If the map exists in a given domain and a client asks about it, YP will serve it. There is, how-
ever, a set of default maps that the YP service serves. The files representing these maps are listed in this description under Files.
For a map to be accessible consistently, it must exist on all YP servers that serve the domain. To provide data consistency between the
replicated maps, an entry to execute the command periodically should be made in the file on each slave server. More information on this
topic is in An entry in the file must not exist, either on a YP master server or on a pure YP client machine.
The YP maps should contain two distinguished key-value pairs. The first is the key YP_LAST_MODIFIED, whose value is a 10-character ASCII
order number. The order number should be the UNIX time in seconds when the map was built. The second key is YP_MASTER_NAME, with the name
of the YP master server as a value. The command generates both key-value pairs automatically. A map that does not contain both key-value
pairs can be served by the YP, but the process will not be able to return values for ``Get order number'' or ``Get master name'' requests.
In addition, values of these two keys are used by when it transfers a map from a master YP server to a slave.
Before they can be properly accessed, the YP maps must be initially set up for both masters and slaves by using the function. Further, YP
maps must be generated and modified only at the master server location. Copies of the master server YP maps can then be transferred to the
slave servers using the function. If is unable to determine a map's location, or if it is unable to determine whether the local copy is
more recent than the master copy, extra command line switches must be set when it is executed.
After the server data bases are set up, the contents of some maps may change. In general, some ASCII source version of the data base
exists on the master. This version should be changed with a standard text editor. The update is incorporated into the YP map and is prop-
agated from the master to the slaves by running All maps must have entries in If a YP map is added, the must be edited to support the new
map. The makefile uses to generate the YP map on the master, and to propagate the changed map to the slaves. The command is a client of
the map ypservers, which lists all of the YP servers.
