Evaluating the security of OpenWRT (part 2) – bugfix

Sep 23 2014 Published by under blog

I had a bug applying the RELRO flag to busybox, this is fixed in GitHub now.

For some reason the build links the busybox binary a second time and I missed the flag.

Also an omission from my prior blog entry: uClibc has RELRO turned on in its configuration already in OpenWRT, so does not need flags passing through to it. However, it is failing to build its libraries with RELRO in all cases, in spite of the flag. This problem doesn’t happen in a standalone uClibc build from the latest uClibc trunk, but I haven’t scoped how to get uClibc trunk into OpenWRT. This may have been unclear they way I described it.

Take a breather

After an overly hectic six months I have a week off, woot!

I have a backlog of tech stuff to blog about.

I just purchased my ticket to LCA2013 in Canberra at the end of January. I am intending to get there Sunday arvo to go to the newcomers session, technically I am not a newcomer as such any more, but I missed it last year which was my first.

It turns out that I am going to get to OSDC in Sydney next month as well.

Fun times ahead :-)

While I was typing this, there was a bushfire (really a scrub fire) 20k north of our place – my wife is out there somewhere in command of a CFS truck. I took the photo an hour ago, and now I walked out for another look the smoke has subsided, so they seem to have it under control.Fire north of Avon

Using SSHFS with a specific identity

The program sshfs is a Linux tool which lets you mount a remote directory accessible via the SSH protocl as a filesystem over fuse. However it defaults to using ‘id_rsa’ as the SSH identity and there are no direct command line options for selecting an alternate identity, or for that matter other SSH parameters such as the TCP port to connect to.
