If you have a patched kernel without a patched nfs-utils, then attempts to mount when all ephemeral ports are already a part of at least 1 TCP connection will fail with an EADDRINUSE from mount.nfs(8) attempting to call bind(2). It will never get around to calling mount(2) and never enter the kernel RPC code. If you have a patched nfs-utils without a patched kernel, its a little unfortunate in that mount.nfs(8) will call mount(2), but that will give an EIO when `xs_bind' tries to call `kernel_bind' which returns EADDRINUSE. I say unfortunate because in this scenario you get the less helpful EIO back from mount(2) rather than the EADDRINUSE from bind(2), meaning the end user sees "input/output error" rather than "address already in use," where the latter is the real issue. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
