#16323: BWAuth on FreeBSD 10

---------------------+------------------------
 I'm attempting to run BWAuth scanner code in a FreeBSD 10 jail as a test
 to see if it will work at all on FreeBSD 10. This assumes you've used
 ezjail to make a jailed machine - I used a jail behind a NAT for ease of
 use. The ezjail steps are out of scope but should be around three commands
 if NAT or a public IP is already assigned to your box.

 First - we need to install some packages:

   pkg install bash python27 py27-virtualenv py27-sqlite3 py27-sqlite3
 sqlite3 py27-sqlite3dbm sqlite
   pkg install automake libevent2 gmake openssl

 I suggest the following patch:
 {{{

  crontab -l

 }}}

 Then run everything as an unpriv user:
 {{{
  git clone https://git.torproject.org/torflow.git
  cd torflow/NetworkScanners/BwAuthority
  ./setup.sh
 }}}

 If Tor fails to build, we'll see the following:
 {{{
 $ ./setup.sh
 /usr/home/builder/torflow
 /usr/home/builder/torflow/NetworkScanners/BwAuthority
 /usr/home/builder/torflow/NetworkScanners/BwAuthority
 /usr/home/builder /usr/home/builder/torflow/NetworkScanners/BwAuthority
 fatal: destination path 'tor' already exists and is not an empty
 directory.
 }}}

 Just remove Tor and ensure you have proper build deps:
 {{{
 rm -rf ../../../tor
 }}}

 If Tor fails to build:
 {{{

          ^
 1 error generated.

 make[1]: stopped in /usr/home/builder/tor
 *** [all] Error code 2

 make: stopped in /usr/home/builder/tor
 1 error

 make: stopped in /usr/home/builder/tor
 }}}

 The above error means that make was running with {{{-j4}}} - please apply
 the above patch and try again.

 {{{
     In file included from src/module.c:24:
     src/connection.h:33:10: fatal error: 'sqlite3.h' file not found
     #include "sqlite3.h"
              ^
     1 error generated.
     error: command 'cc' failed with exit status 1
 }}}

 This means you need to tell cc where to find {{{sqlite3.h}}}

 {{{
 export CPPFLAGS=-I/usr/local/include
 }}}

 Run setup.sh again - it may error out like so:
 {{{
 crontab: usage error: file name must be specified for replace
 usage: crontab [-u user] file
        crontab [-u user] { -e | -l | -r }
 }}}

 This means you didn't apply the above patch for crontab (on BSD it expects
 {{{-}} or a file name but not an empty string, I guess).

 {{{
   cd torflow/NetworkScanners/BwAuthority
   export CPPFLAGS=-I/usr/local/include
   ./setup.sh
 }}}

 The patch adds {{{-e}}} and {{{-x}}} which makes debugging easier -
 {{{-x}}} could be removed.

 It looks like it may even work:
