- Summary
- net: ethernet: ti: am65-cpsw: fix memleak in certain XDP cases
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: ti: am65-cpsw: fix memleak in certain XDP cases
If the XDP program doesn't result in XDPPASS then we leak the memory allocated by am65cpswbuildskb().
It is pointless to allocate SKB memory before running the XDP program as we would be wasting CPU cycles for cases other than XDP_PASS. Move the SKB allocation after evaluating the XDP program result.
This fixes the memleak. A performance boost is seen for XDP_DROP test.
XDP_DROP test: Before: 460256 rx/s 0 err/s After: 784130 rx/s 0 err/s
