Hey all,

I recently used a testing program to test the 4.19 stable branch kernel and found that a crash occurred immediately. The test source code link is: https://github.com/Backmyheart/src0358/blob/master/vxlan_fdb_destroy.c

The test command is as follows: gcc vxlan_fdb_destroy.c -o vxlan_fdb_destroy -lpthread

According to its stack, upstream has relevant repair patch, the commit id is 7c31e54aeee517d1318dfc0bde9fa7de75893dc6.

May i ask if the 4.19 kernel will port this patch ?

Have you tested to verify that it does work? If so, please provide the working patch because as-is, it does not apply to 4.19.y at all.

thansk,
