SubjectRe: WARNING in rfkill_alloc
From
Date
Hi,

> RIP: 0010:rfkill_alloc+0x2c0/0x380 net/rfkill/core.c:930

This seems pretty obvious - there's no name given.

> wiphy_new_nm+0x159c/0x21d0 net/wireless/core.c:487
> ieee80211_alloc_hw_nm+0x4b4/0x2140 net/mac80211/main.c:531

which is strange, because we try to validate the name here.

Can you help me read this?

sendmsg$nl_generic(r1, &(0x7f0000b3e000-0x38)={&(0x7f0000d4a000-
0xc)={0x10, 0x0, 0x0, 0x0}, 0xc,
&(0x7f0000007000)={&(0x7f00001ca000)={0x14, 0x1c, 0x109,
0xffffffffffffffff, 0xffffffffffffffff, {0x4, 0x0, 0x0}, []}, 0x14},
0x1, 0x0, 0x0, 0x0}, 0x0)

I've reformatted it as

sendmsg$nl_generic(
r1,
&(0x7f0000b3e000-0x38)={
addr= &(0x7f0000d4a000-0xc)={
0x10, 0x0, 0x0, 0x0
},
addrlen=0xc,
vec= &(0x7f0000007000)={
ptr= &(0x7f00001ca000)={
0x14, 0x1c, 0x109, 0xffffffffffffffff,
0xffffffffffffffff, {0x4, 0x0, 0x0}, []
},
len= 0x14
},
vlen= 0x1,
ctrl= 0x0,
ctrllen=0x0,
f= 0x0
},
0x0
)

but am still getting lost - what exactly is the *byte* sequence inside
the (full) message (including headers)?


Ah, then again, now I see the fault injection - I guess dev_set_name()
just failed and we didn't check the return value, will fix that.
