[PATCH][next] bpf: fix memory leak on object 'data'

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

 



From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The error return path on when bpf_fentry_test* tests fail does not
kfree 'data'. Fix this by adding the missing kfree.

Addresses-Coverity: ("Resource leak")
Fixes: faeb2dce084a ("bpf: Add kernel test functions for fentry testing")
