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
