darwin and freebsd.

Fix the net.ConnectionsMax BUG 
`connectionsList, err := net.ConnectionsMax("tcp4", 1000)`
when you run net.ConnectionsMax,you will find some proc is not equal with the `netstat -lptn`

Segflow 86c7289ccc Fix: use filename in exec.LookPath instead of full path 
exec.LookPath searches for the file in the $PATH, which mean giving it an absolute path is against it's own purposes.

Lomanic ef54649286 [windows] Use windows.NewLazySystemDLL to (possibly) prevent DLL hijacking 
Might be useless because of https://docs.microsoft.com/en-us/windows/desktop/dlls/dynamic-link-library-search-order#search-order-for-desktop-applications
but better be safe than sorry.

Laurie Clark-Michalek 413cb32b6c Use static initialisation for invoke instances, instead of init funcs 
The order of init function execution is dependant on the order that the
source files are passed to the compiler. This causes issues when
building under other build systems, such as bazel or buck, as they are
not guarenteed to maintain the same file order as the default go tool.

Move from the `syscall` package to the `golang.org/x/sys/{unix,windows}` 2017-06-02 13:51:00 -07:00
Alexander Blagoev b32353f094 Add comments with a short explanation and link to the PR request 2017-05-04 14:52:34 +03:00
Alexander Blagoev 531f9507d2 Read /proc/net files with a single read syscall. 
The /proc/net files are not guaranteed to be consistent, they are only
consitent on the row level. This is probably one of the reasons why
consequent read calls might return duplicate entries - the kernel is
changing the file as it is being read. In certain situations this might
lead to loop like situations - the same net entry is being returned when
reading the file as new connections are added to the kernel tcp table, i.e
there can be a lot of duplications.

This commit is trying to reduce the duplications, by fetching the contents
of the net files with a single read syscall.

Conor Branagan 276c873f0d Fast duplication check in inodes processing. 
Instead of encoding a JSON string of each connection (non-trivial at high
connection volumes) we can use the connTmp struct for map look-ups if we
eliminate the unused `uids` field.

Also switches to using the empty struct instead of bool for zero memory
overhead.
