[PATCH v1] libnvdimm, dax: Fix a missing check in nd_dax_probe()
From: Yingjie Wang
In nd_dax_probe(), nd_dax_alloc() may fail and return NULL.
Check for NULL before attempting to
use nd_dax to avoid a NULL pointer dereference.

[PATCH v1] ipv4: add iPv4_is_multicast() check in ip_mc_leave_group().
From: Yingjie Wang
There is no iPv4_is_multicast() check added to ip_mc_leave_group()
to check if imr->imr_multiaddr.s_addr is a multicast address.
If not a multicast address, it may result in an error.
In some cases, the callers of ip_mc_leave_group() don't check
whether it is multicast address or not before calling
such as do_ip_setsockopt(). So I suggest adding the ipv4_is_multicast()
check to the ip_mc_leave_group() to prevent this from happening.

There is no IPv4_is_multicast() check added to ip_mc_leave_group()
to determine whether imr->imr_multiaddr.s_addr is a multicast address.
If not a multicast address, it may result in an error.
In some cases, the callers of ip_mc_leave_group don't check
whether it is multicast address or not such as do_ip_setsockopt().
So I suggest added the ipv4_is_multicast() check to the

From: Yingjie Wang In rvu_mbox_handler_cgx_mac_addr_get() and rvu_mbox_handler_cgx_mac_addr_set(), the msg is expected only from PFs that are mapped to CGX LMACs. It should be checked before mapping, so we add the is_cgx_config_permitted() in the functions.
