The 'Program name' part is fetched from /proc/<pid>/cmdline, then mangled
before presentation. Mangling is done in netstat.c, function 'dir_act'.
The function assumes cmdline is a file path and extracts the basename.
Obviously that assumption is not always correct. It's not unusual a
cmdline looks like this:
sshd: foo@pts/48
or like this:
sshd: foo [priv]
Function 'bb_basename' uses strrchr everything up to and including the
last occurrence och character '/'. The result is (see first example
above):
PID/Program name
12345/48
or (second example):
PID/Program name
12345/sshd: foo [priv]
Neither is desirable.
I'd like to propose a different way to do that:
1. strip everything after and including the first whitespace character
2. maybe remove even odd ':' character at the end of the string
3. call bb_basename after that
Output would then look like:
PID/Program name
12345/sshd
which is what one would expect.
Thoughts?
Cheers,
