That's the wrong ops struct? I think I was looking at the "previous report" that Johannes mentioned where it was crashing because virt_wifi doesn't implement a set_wiphy_params function. Smatch says there are two other drivers, the libertas and ipw2x00 which don't have a set_wiphy_params function either. But maybe those handle it a different way. drivers/net/wireless/marvell/libertas/cfg.c | (null) | (struct cfg80211_ops)->set_wiphy_params | 0 drivers/net/wireless/virt_wifi.c | (null) | (struct cfg80211_ops)->set_wiphy_params | 0 drivers/net/wireless/intel/ipw2x00/libipw_module.c | (null) | (struct cfg80211_ops)->set_wiphy_params | 0 regards, dan carpenter On Fri, Jan 10, 2020 at 09:23:57PM -0800, Justin Capella wrote: > I noticed pfifo_qdisc_ops is exported as default_qdisc_ops is it > possible this is how rdev->ops is NULL > > Seems unlikely, but thought I'd point it out. > > > On Fri, Jan 10, 2020 at 11:13 AM Johannes Berg > <johannes@xxxxxxxxxxxxxxxx> wrote: > > > > On Fri, 2020-01-10 at 11:11 -0800, syzbot wrote: > > > Hello, > > > > > > syzbot found the following crash on: > > > > > > HEAD commit: 2f806c2a Merge branch 'net-ungraft-prio' > > > git tree: net > > > console output: https://syzkaller.appspot.com/x/log.txt?x=1032069ee00000 > > > kernel config: https://syzkaller.appspot.com/x/.config?x=5c90cac8f1f8c619 > > > dashboard link: https://syzkaller.appspot.com/bug?extid=34b582cf32c1db008f8e > > > compiler: gcc (GCC) 9.0.0 20181231 (experimental) > > > > > > Unfortunately, I don't have any reproducer for this crash yet. > > > > It's quite likely also in virt_wifi, evidently that has some issues. > > > > Cody, did you take a look at the previous report by any chance? > > > > johannes > > > > -- > You received this message because you are subscribed to the Google Groups "syzkaller-bugs" group. > To unsubscribe from this group and stop receiving emails from it, send an email to syzkaller-bugs+unsubscribe@xxxxxxxxxxxxxxxx. > To view this discussion on the web visit https://groups.google.com/d/msgid/syzkaller-bugs/CAMrEMU_a9evtp26tYB6VUxznmSmH98AmpP8xnejQr5bGTgE%2B8g%40mail.gmail.com.
