Suggested extensions to python-inet_diag library

[James Hulka]

In looking for faster way to retrieve information about open sockets on
a system I stumbled across python-inet_diag.

The library is very useful however it was missing the query / filter
code found in socketstat (Alexey Kuznetsov) which it seems to be based on.

I would like to propose the following patches to implement source and
destination IP and port filters for the inet_diag.create function.

Best Regards,

James Hulka

socketstat_filter.patch :
inet_diag.c: added filter building code from socketstat (Alexey
Kuznetsov, <***@ms2.inr.ac.ru>)
added filter options to create function
added create function documentation

diag_filter.h: new header file
added various filter condition constants
added diag_filter structure

process_info.patch :
inet_diag.c: added process info parsing from socketstat (Alexey
Kuznetsov, <***@ms2.inr.ac.ru>)

req_v2.patch :
inet_diag.c: using req_v2 and specifying protocol type in header
retreiving full process path
return proc as struct

leak_fixes.patch :
inet_diag.c: cleanup memory leaks and reformat
memory cleanup user_ent_hash

inet_diag_copy.h: unused removed

listening_states.patch :
inet_diag.c: added listening states constant
added process, pid and fd getter functions
cleanup memory leaks and reformat
memory cleanup user_ent_hash

After ARM architecture testing I added the following change to my
suggested extensions to python-inet_diag in order to support
inet_diag_req when TCPDIAG_GETSOCK and DCCPDIAG_GETSOCK are passed as
socktype.

Best Regards,

James

i just tested your additions on x86_64, armv7hl and ppc64.
it seems to work (tested using tuna, pss and psk), except unix sockets, which are not implemented at all.
