Bug 166300 – madwifi-old-0.0.1417.20060128 fails to compile under 2.6.20+

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Itay Greenspon 2007-02-11 07:22:17 UTC]

Offending module: ieee80211_crypto_ccmp.c

Error Message:
ieee80211_crypto_ccmp.c:290: error: invalid use of undefined type 'struct page'
ieee80211_crypto_ccmp.c:294: error: invalid use of undefined type 'struct page'

Code reference:
static void
rijndael_encrypt(struct crypto_tfm *tfm, const void *src, void *dst) {
{
        struct scatterlist sg_src;
        struct scatterlist sg_dst;

----->  sg_src.page = virt_to_page(src);   <---------------- ERROR
        sg_src.offset = offset_in_page(src);
        sg_src.length = AES_BLOCK_LEN;

----->  sg_dst.page = virt_to_page(dst);   <---------------- ERROR
        sg_dst.offset = offset_in_page(dst);
        sg_dst.length = AES_BLOCK_LEN;
        crypto_cipher_encrypt(tfm, &sg_dst, &sg_src, AES_BLOCK_LEN);
}

I believe this is not the only file with the problem (i assume dot1x would be similairly affected)

Additional Problems:
The Sandbox violation also exists in this version (there is a seperate bug for this)
The header file "config.h" has been removed from /usr/src/linux/include/linux/config.h, but is required by madwifi-old. (should be fixed as this is a stub header file for <linux/autoconf.h>)

care to provide a patch for the problem? I dont think anyone else cares enough to write one.

Patch to help madwifi-old compile with kernel 2.6.20

[Comment 3 Stefan Schweizer (RETIRED) 2007-02-12 23:04:54 UTC]

sorry, does not apply here. Can you please give an ebuild for applying it too?

Apply it manualy

Hi, 
This is corrected version.

Apply it manually by moving into the madwifi-old work-dir:
cd /var/tmp/portage/net-wireless/madwifi-old-0.0.1417.20060128/work/madwifi-old-r1417-20060128/

madwifi-old-r1417-20060128 # patch -p0 < [path to where you saved ieee80211_crypto_ccmp.patch]


The driver will then compile, however... it is unstable.
I think it's best to move to madwifi-ng if possible.
(I'll give it another try.. though it didn't work for me at first)

thanks, I committed this.

[Comment 6 A. Person 2007-02-25 22:32:50 UTC]

I get a failed patch error for patch 2.6.20 when trying to emerge madwifi-old.  Is that related to this?

[Comment 7 Stefan Schweizer (RETIRED) 2007-02-26 00:31:24 UTC]

seems I got the wrong patch, should work now, thanks.
