There is a missing constant for IP_TRANSPARENT on linux.

s.setsockopt(Socket::SOL_IP, 19, 1)
The 19 suppose to be as a constant named: IP_TRANSPARENT or Socket::IP_TRANSPARENT.

This is Linux-specific and only defined in linux headers
such as /usr/include/linux/in.h.

I'm not sure applications can safely use such headers.

We already have Linux-specific constants (e.g. TCP_CORK) and
*BSD-specific constants (e.g. TCP_NOPUSH), so I don't think we should
make it hard for users to take advantage of non-portable features on
their favorite OS.

I vote for adding IP_TRANSPARENT (and any other OS-specific constants
users request).

It is not my concern.
TCP_CORK is defined in /usr/include/netinet/tcp.h which is a glibc header.

  • ext/socket/mkconstants.rb: Add IP_TRANSPARENT.
    IP_TRANSPARENT is provieded since glibc-2.12.
    Reported by Eliezer Croitoru. [ruby-core:50372] [Bug #7476]

Updated by akr (Akira Tanaka) over 10 years ago

It seems glibc-2.12 provides IP_TRANSPARENT.
So there is no problem to use it now.
