From: Ben Greear <greearb@xxxxxxxxxxxxxxx> The 4.9 kernel, at least, can return EEXIST when trying to auth a station that already exists. Signed-off-by: Ben Greear <greearb@xxxxxxxxxxxxxxx> --- NOTE: I cannot manage to compile top-of-tree hostapd, due to this: [greearb@ben-dt3 hostapd]$ make ../src/drivers/driver_nl80211.c:17:31: fatal error: netlink/genl/genl.h: No such file or directory compilation terminated. Makefile:1247: recipe for target '../src/drivers/driver_nl80211.o' failed make: *** [../src/drivers/driver_nl80211.o] Error 1 So, this patch is not even properly compile tested unfortunately. We have seen this bug in multiple places, but it is difficult to reproduce.
