[PATCH 6.6 064/301] vxlan: Add missing VNI filter counter update in arp_reduce().

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


6.6-stable review patch.  If anyone has any objections, please let me know.


From: Guillaume Nault <gnault@xxxxxxxxxx>

[ Upstream commit b22ea4ef4c3438817fcb604255b55b0058ed8c64 ]

VXLAN stores per-VNI statistics using vxlan_vnifilter_count().
These statistics were not updated when arp_reduce() failed its
pskb_may_pull() call.

Use vxlan_vnifilter_count() to update the VNI counter when that
