In the latest mainline. we can filter the following result by the key word "leak" in net/sunrpc/auth_gss. 0070ed3 Fix 16-byte memory leak in gssp_accept_sec_context_upcall (has been tested, Fail to work) 78794d1 svcrpc: don't leak contexts on PROC_DESTROY (has been tested, Fail to work) a1d1e9b svcrpc: fix memory leak in gssp_accept_sec_context_upcall (Not yet) e9776d0 SUNRPC: Fix a pipe_version reference leak (Not yet) cdead7c SUNRPC: Fix a potential memory leak in auth_gss (Not yet) 980e5a4 nfsd: fix rsi_cache reference count leak (Not yet) 07a2bf1 SUNRPC: Fix a memory leak in gss_create() (Not yet) 3ab9bb7 SUNRPC: Fix a memory leak in the auth credcache code (existed) 54f9247 knfsd: fix resource leak resulting in module refcount leak for rpcsec_gss_krb5.ko (existed) b797b5b [PATCH] knfsd: svcrpc: fix gss krb5i memory leak (existed) d4a30e7 RPCSEC_GSS: fix leak in krb5 code caused by superfluous kmalloc (Not yet) I suspect that commit d4a30e7 ("RPCSEC_GSS: fix leak in krb5 code caused by superfluous kmalloc") will solve the issue. Further, I will adjust the patch to 3.10. and see what it will happen. Actually I am not sure. :-[ Thanks, zhong jiang.
