excessive CPU usage during fake auth. and injection

[zack]

Fake auth. and injection in conjunction with airodump-ng results in excessive CPU utilization.

Here are 2 screenshots:

1. This one shows draining the cpu during fake auth. with normal parameters: -1 0 -a xxx mon0 (hihgcpu.png)
2. That one shows aireplay-ng injecting and airodump-ng collecting (cpufake.png)

Facts:

• P4 mobile cpu
• kernel 2.6.28-13 /ubuntu 9/
• fedora 11 kernel .29
• on both gnome and kde
• lastest svn of aircrack-ng
• issue with b43, zd1211rw and rtl8187

For me work without problems.
Tested with:
Ubuntu 8.04 32 bit (Kernel 2.24.24)
Ubuntu 9.04 32 bit (Kernel 2.6.28)
Alfa + r8187

RC1 could not compile on Ubuntu 9.04 so I compiled RC2 of aircrack-ng -- the results are the same. Excessive CPU drainage. If there's a bug in the code, it surely dates from much older versions.

Let me know if I can be of some further assistance.

What are the compilation errors of rc1 on ubuntu 9.04? I'm nearly sure they are easy to fix.
