792  *
793  * When passed the -u option, netstat presents additional information against
794  * each socket showing the associated process ID(s), user(s) and command(s).
795  *
796  * The kernel provides some additional information for each socket, namely:
797  *   - inode;
798  *   - address family;
799  *   - socket type;
800  *   - major number;
801  *   - flags.
802  *
803  * Netstat must correlate this information against processes running on the
804  * system and the files which they have open.
805  *
806  * It does this by traversing /proc and checking each process' open files,
807  * looking for BSD sockets or file descriptors relating to TLI/XTI sockets.
808  * When it finds one, it retrieves information and records it in the
809  * 'process_table' hash table with the entry hashed by its inode.
810  *
811  * For a BSD socket, libproc is used to grab the process and retrieve
812  * further information. This is not necessary for TLI/XTI sockets since the
813  * information can be derived directly via stat().
814  *
815  * Note that each socket can be associated with more than one process.

5196  * Common info-gathering routine for all transports.
5197  *
5198  * The linked list of MIB data pointed to by item consists of a number of
5199  * tables covering several protocol families and socket types, one after
5200  * another. These are generally tables containing information about network
5201  * connections, such as mib2_tcpConnEntry, as defined in RFC 1213/4022.
5202  *
5203  * There are also ancilliary tables which contain optional additional
5204  * information about each socket. The data in these ancilliary tables is
5205  * indexed by the table position of the connection to which it relates, and
5206  * data may not be available for all connections.
5207  *
5208  * The code here determines the size of the connection table, allocates an
5209  * array of that size to hold the ancilliary data and then fills that in
5210  * if data is present.
5211  *
5212  * As an example, if the data contains a mib2_tcpConnEntry table containing
5213  * three connections, but there is no ancilliary data for the second, then
5214  * the accompanying mib2_socketInfoEntry table will only contain two entries.
5215  * However, the first entry is tagged as referring to connection slot 0, and
5216  * the second is tagged with connection slot 2.
5217  * This function would return an array with:
5218  * { <data for conn0>, NULL, <data for conn2> }
