David Ramos a1d1e9be5a svcrpc: fix memory leak in gssp_accept_sec_context_upcall ... Our UC-KLEE tool found a kernel memory leak of 512 bytes (on x86_64) for each call to gssp_accept_sec_context_upcall() (net/sunrpc/auth_gss/gss_rpc_upcall.c). Since it appears that this call can be triggered by remote connections (at least, from a cursory a glance at the call chain), it may be exploitable to cause kernel memory exhaustion. We found the bug in kernel 3.16.3, but it appears to date back to commit 9dfd87da1a (2013-08-20). The gssp_accept_sec_context_upcall() function performs a pair of calls to gssp_alloc_receive_pages() and gssp_free_receive_pages(). The first allocates memory for arg->pages. The second then frees the pages pointed to by the arg->pages array, but not the array itself. Reported-by: David A. Ramos <daramos@stanford.edu> Fixes: 9dfd87da1a ("rpc: fix huge kmalloc's in gss-proxy”) Signed-off-by: David A. Ramos <daramos@stanford.edu> Signed-off-by: J.
