hostapd crash

[e9hack]

Hi,

I did add one more AP to my wifi config for testing. This results in hostapd not starting for this device:

Thu Jan 11 13:59:12 2024 daemon.notice hostapd: Exception in ubus function: left-hand side expression is null In __iface_pending_next(), file /usr/share/hostap/hostapd.uc, line 165, byte 73:   called from function iface_pending_next (/usr/share/hostap/hostapd.uc:181:73)   called from function iface_pending_init (/usr/share/hostap/hostapd.uc:222:15)   called from function iface_restart (/usr/share/hostap/hostapd.uc:249:35)   called from function iface_set_config (/usr/share/hostap/hostapd.uc:620:52)   called from function [anonymous function] (/usr/share/hostap/hostapd.uc:827:32)   called from anonymous function (/usr/share/hostap/hostapd.uc:710:22)   `            hostapd.printf(`hostapd.add_iface failed for phy ${phy} ifname=${bss.ifname}`);`   Near here -----------------------------------------------------------------------^

My hostapd.uc is modified. The affected line number does have an offset by 1 related to the original file:

diff --git a/package/network/services/hostapd/files/hostapd.uc b/package/network/services/hostapd/files/hostapd.uc

  function iface_remove(cfg)


The error doesn't appear when I remove a AP. It doesn't matter which one I remove.

Is there somewhere a buffer to small?
