From: Dave Johnson <djohnson+linux-kernel@sw.starentnetworks.com> sendmsg()/recvmsg() syscalls from o32/n32 apps to a 64bit kernel will cause a kernel memory leak if iov_len > UIO_FASTIOV for each syscall! This is because both sys_sendmsg() and verify_compat_iovec() kmalloc a new iovec structure. Only the one from sys_sendmsg() is free'ed. I wrote a simple test program to confirm this after identifying the problem: http://davej.org/programs/testsendmsg.c Note that the below fix will break solaris_sendmsg()/solaris_recvmsg() as it also calls verify_compat_iovec() but expects it to malloc internally.
