torsocks fails open on Mac OS X 10.11
I am running OSX 10.11 and since the update I just noticed that torsocks is failing to torify connections.
Here are the details of my system:
$ torsocks --version
Torsocks 2.1.0
$ uname -a
Darwin XXX 15.0.0 Darwin Kernel Version 15.0.0: Sat Sep 19 15:53:46 PDT 2015; root:xnu-3247.10.11~1/RELEASE_X86_64 x86_64
$ sw_vers -productVersion
10.11.1
Doing a cursory search into what may be the causes for this problem it seems like a security "feature" introduced in OSX 10.11 is to blame for this behaviour called System Integrity Protection [1]. Looking around there are other people complaining about the fact that DYLD_INSERT_LIBRARIES
doesn't work in OSX 10.11 [2].
This stackoverflow article does a nice summary of what can be done and can't be done due to SIP: http://apple.stackexchange.com/questions/193368/what-is-the-rootless-feature-in-el-capitan-really.
I am not sure what can be done to overcome this limitation in the latest version of OSX, but I think that at least torsocks should implement a check for the OSX version and if it's greater than 10.10 it fails closed (without doing the non-torified request).
