Title:
wireless injection doesnt work due to channel bug
Status in “linux” package in Ubuntu:
Expired
Bug description:
amazingly enough, the linux kernel shipped with ubuntu has all that is
needed for packet injection on wireless interfaces, if not for one bug
making it useless. the bug is related to channel selection, which
refuses to get set, showing up as -1 for other programs, like
aircrack.
steps to reproduce:
1- have a wireless card with drivers that can inject (i tested ralink
drivers, rtl8192ce and iwlwifi)
2- install aircrack (from source, or deb package - sadly, not available in
precise, but debs from oneiric work)
3- sudo airmon-ng start wlan0 1
4- iwconfig (note the lack of channel frequency on created interface)
5- run aireplay-ng in any mode except test mode, you'll get a complaint about
negative channel.
please note, verifying this bug with bleeding edge compat-wireless
makes no sense at all, since major modifications to drivers have
happened, and the current state of compat-wireless injection is
riddled with regressions.
fortunately, there is a simple solution, a patch available at:
http://patches.aircrack-ng.org/channel-negative-one-maxim.patch
i took the time to download, on precise, the ubuntu linux source
package, unpacked it, applied the supplied diff, applied the patch
linked above, and ran the compilation as per instruction in the ubuntu
wiki for compiling kernels. the end result was the linux image,
headers, and tools .deb packages, which i installed. then unloaded the
wireless driver (i was on a laptop using iwlwifi, a centrino 6xxx
card), and loaded it again (just to make sure the new one is loaded),
and tested injection, worked flawlessly.
so basically, it's just one patch, and you could make all people
relying on injection, happy as they can work with stock distro kernels
:)
thanks
