| H A D | syscallsubr.h | diff 160765 Thu Jul 27 17:54:41 MDT 2006 jhb Fix a file descriptor race I reintroduced when I split accept1() up into kern_accept() and accept1(). If another thread closed the new file descriptor and the first thread later got an error trying to copyout the socket address, then it would attempt to close the wrong file object. To fix, add a struct file ** argument to kern_accept(). If it is non-NULL, then on success kern_accept() will store a pointer to the new file object there and not release any of the references. It is up to the calling code to drop the references appropriately (including a call to fdclose() in case of error to safely handle the aforementioned race). While I'm at it, go ahead and fix the svr4 streams code to not leak the accept fd if it gets an error trying to copyout the streams structures. |
