Description Andrew Ross (RETIRED) gentoo-dev

ipw2200 v0.4+ requires the kernel to have CONFIG_CRYPTO_ARC4 set. The ebuild currently checks for CONFIG_CRC32 and CONFIG_FW_LOADER (which are also required), but not CONFIG_CRYPTO_ARC4.

The ipw2200 author (James Ketrenos) introduced the new dependency in an email to mailling list:

http://article.gmane.org/gmane.linux.drivers.ipw2100.devel/1379

Since the ebuild allows the ipw2200 kernel module to be built even when CONFIG_CRYPTO_ARC4 is not set, setting the WEP key fails.

Reproducible: Always
Steps to Reproduce:
1. compile and install a kernel with CONFIG_CRYPTO_ARC4 not set
2. emerge =net-wireless/ipw2200-0.4
3. modprobe ipw2200
4. iwconfig ethX key [your key]

Actual Results:  
ebuild and modprobe completed successfully.

iwconfig command fails with following error message:

Error for wireless request "Set Encode" (8B2A) :
    SET failed on device eth2 ; Operation not supported.

Relevant dmesg output:

ieee80211_crypt_wep: could not allocate crypto API arc4
eth2: could not initialize WEP: load module ieee80211_crypt_wep.o

Expected Results:  
ebuild should die and inform user than CONFIG_CRYPTO_ARC4 must be set.

This has been fixed -- additionally the -r1 ebuild builds support for WPA.
