From: Johannes Berg <johannes.berg@intel.com>

Split the bss_info_changed method to vif_cfg_changed and
link_info_changed, with the latter getting a link ID.
Also change the 'changed' parameter to u64 already, we
know we need that.

just curious about the typecasting.

https://www.kernel.org/doc/html/latest/core-api/printk-formats.html 
indicates we should always be able to use %lld or %llx for u64 hence no 
typecasting should be needed

Hi Johannes,

I think you/someone will change here later for the "/* FIXME: should be 
for each link */", right?

It lead error/kernel crash as below while reconfig single MLO link which 
link id is 2.
When test with single MLO link which link id is 0, not found 
error/kernel crash.

I think it is because the sdata->vif.bss_conf link id is 0, but
the actual MLO link id is 2 when error/kernel crash happened.

Now I did a temp workaround to skip the crash.

Maybe. I'm not actually sure it's really needed, it depends how we use
this in the future.

I'm not surprised, I just worked on fixing reconfig in the last few
days, will post it after some more review/testing.

So I think that might not need changes *here*, but rather a proper FW
restart. Which I haven't tested in AP mode though -- was the crash in AP
mode?

Thanks.

It is crash in station mode.

Conflict happened while run "git am" the patch.

Because missing the  "changed |= BSS_CHANGED_EHT_PUNCTURING;" in my 
local code,

also it is missing in 
https://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next.git/tree/net/mac80211/util.c

Maybe "changed |= BSS_CHANGED_EHT_PUNCTURING;" is only existed in your 
local code?

Ah yes, we didn't upstream that because there's still this discussion
about handling puncturing. But you can probably apply around that.

Yes, after apply it.

and apply "commit 3d901102922723eedce6ef10ebd03315a7abb8a5 wifi: 
mac80211: implement link switching" to

fix build error because my local code is not latest.

it is built success, I will try it later.

Hi johannes,

After above change, no error/kernel crash happened while reconfig single 
MLO link which link id is 2.

Hi Johannes,

I see this patch https://p.sipsolutions.net/0652bbbbe350b126.txt is not 
merged to 
https://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next.git/tree/net/mac80211/util.c

will your merge it later?
