From a1a8064169aeda79e3266a2db9cce25e361a86dc Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Mon, 20 Mar 2017 18:10:36 +0100 Subject: remove RPC implementation The included RPC implementation is ipv4 only. Other C library projects have either deprecated the internal RPC implementation (GNU C Library) or never implemented such functionality (musl C Library). The latest rpcbind release (0.2.4) checks for libtirpc and does not allow to be build with uClibc-ng RPC without patching. The common use case for RPC nowadays is to use rpcbind together with nfs-utils to provide NFS server or client support to a system. The included RPC implementation does create issues with duplicate symbol failures when statically compiling with RPC enabled. --- libc/inet/rpc/rpc_thread.c | 163 --------------------------------------------- 1 file changed, 163 deletions(-) delete mode 100644 libc/inet/rpc/rpc_thread.c (limited to 'libc/inet/rpc/rpc_thread.c') diff --git a/libc/inet/rpc/rpc_thread.c b/libc/inet/rpc/rpc_thread.c deleted file mode 100644 index d8d753421..000000000 --- a/libc/inet/rpc/rpc_thread.c +++ /dev/null @@ -1,163 +0,0 @@ -/* - * Copyright (C) 2000-2006 Erik Andersen - * - * Licensed under the LGPL v2.1, see the file COPYING.LIB in this tarball. - */ - -#include -#include -#include "rpc_private.h" - - -#ifdef __UCLIBC_HAS_THREADS__ - -#include -#include - -/* Variable used in non-threaded applications or for the first thread. */ -static struct rpc_thread_variables __libc_tsd_RPC_VARS_mem; -__libc_tsd_define (, RPC_VARS) - -/* - * Task-variable destructor - */ -void -__rpc_thread_destroy (void) -{ - struct rpc_thread_variables *tvp = __libc_tsd_get (RPC_VARS); - - if (tvp != NULL && tvp != &__libc_tsd_RPC_VARS_mem) { - __rpc_thread_svc_cleanup (); - __rpc_thread_clnt_cleanup (); - /*__rpc_thread_key_cleanup (); */ - free (tvp->clnt_perr_buf_s); - free (tvp->clntraw_private_s); - free (tvp->svcraw_private_s); - free (tvp->authdes_cache_s); - free (tvp->authdes_lru_s); - free (tvp); - __libc_tsd_set (RPC_VARS, NULL); - } -} - -/* - * Initialize RPC multi-threaded operation - */ -static void -rpc_thread_multi (void) -{ - __libc_tsd_set (RPC_VARS, &__libc_tsd_RPC_VARS_mem); -} - - -struct rpc_thread_variables attribute_hidden * -__rpc_thread_variables (void) -{ - __libc_once_define (static, once); - struct rpc_thread_variables *tvp; - - tvp = __libc_tsd_get (RPC_VARS); - if (tvp == NULL) { - __libc_once (once, rpc_thread_multi); - tvp = __libc_tsd_get (RPC_VARS); - if (tvp == NULL) { - tvp = calloc (1, sizeof *tvp); - if (tvp != NULL) - __libc_tsd_set (RPC_VARS, tvp); - else - tvp = __libc_tsd_get (RPC_VARS); - } - } - return tvp; -} - - -/* Global variables If we're single-threaded, or if this is the first - thread using the variable, use the existing global variable.
