Kernel 7.1.1-1-siduction-amd64 und broadcom-sta-dkms mögen sich nicht mehr

[ReinerS]

Beim Upgrade auf 7.1.1-1-siduction-amd64 steigt bei diesem Kernel der build von initramfs wie folgt aus:

Building initial module broadcom-sta/6.30.223.271 for 7.1.1-1-siduction-amd64

Beim Kernel davor (7.0.12-1-siduction-amd64) noch problemlos.

Das log hilft mir auch nicht wirklich weiter:

Jemand eine Idee dazu? Das entsprechende Modul fehlt dann bei dem Kernel und die Netzwerkkarte wird natürlich nicht erkannt.

Hat jemand eine Idee dazu?

Though it's not very comforting, here is the reason why it fails:
Line 83 of  broadcom-sta-dkms_6.30.223.271-29_amd64.deb's file
./usr/src/broadcom-sta-6.30.223.271/src/wl/sys/wl_cfg80211_hybrid.c reads:

#if LINUX_VERSION_CODE < KERNEL_VERSION(3, 16, 0)
static s32
wl_cfg80211_get_station(struct wiphy *wiphy, struct net_device *dev,
                        u8 *mac, struct station_info *sinfo)

83: wl_cfg80211_get_station(struct wiphy *wiphy, struct net_device *dev,
                        const u8 *mac, struct station_info *sinfo)
#endifSo parameter dev points to structure net_device. In line 1859 of the same file
we initialize wl_cfg80211_ops of static structure cfg80211_ops as:
 

Code Select Expand

static struct cfg80211_ops wl_cfg80211_ops = {
        .change_virtual_intf = wl_cfg80211_change_iface,
        .scan = wl_cfg80211_scan,
        .set_wiphy_params = wl_cfg80211_set_wiphy_params,
        .join_ibss = wl_cfg80211_join_ibss,
        .leave_ibss = wl_cfg80211_leave_ibss,
1859:   .get_station = wl_cfg80211_get_station,...
}So we have to look for static structure cfg80211_ops, which is defined in
file /usr/src/linux-headers-7.0.12-1-siduction-amd64/include/net/cfg80211.h
of linux kernel 7.0.12-1 in lines 4901 and 4962 as

4901: struct cfg80211_ops {...
4962:    int     (*get_station)(struct wiphy *wiphy, struct net_device *dev,
                               const u8 *mac, struct station_info *sinfo);
...}However, linux kernel  7.1.1-1-siduction-amd64 in file
/usr/src/linux-headers-7.1.1-1-siduction-amd64/include/net/cfg80211.h
defines it as

Code Select Expand

5080: struct cfg80211_ops {...
5150:    int     (*get_station)(struct wiphy *wiphy, struct wireless_dev *wdev,
                               const u8 *mac, struct station_info *sinfo);
...}in lines 5080 and 5150. So according to broadcom its second parameter is always of
type struct net_device. But this is only compatible with kernel 7.0.12-1, since
kernel 7.1.1-1 defines it of struct wireless_dev, which is completely different.

This is not an easy fix, because subsequent code must be rewritten to accommodate
for the changes. It is possible, though, but very time consuming for a hobbyist.
So I suggest you wait for an update from broadcom-sta.

Maybe it is after all...

So I suggest you keep a copy of original  /usr/src/wl/sys/wl_cfg80211_hybrid.c of
broadcom-sta-dkms_6.30.223.271-29_amd64.deb. Change to /usr/src/wl/sys, apply the patch:
$ patch -p1 < /tmp/patch
(You save the above code as /tmp/patch first)
Then you reconfigure the module build via:
$ sudo dpkg-reconfigure linux-image-7.1.1-1-siduction-amd64

I own no broadcom wireless card, so maybe you can report back whether it works.
