Also, other parts of pppd.h were moved to multilink.h, chap.h, eap.h, eui64.h, and a new options.h. * Provide an API for access to data that is needed by plugins (in no particular order): - ifname - ifunit - remote_name - remote_number - peer_authname - status (now called "code" internally) - phase - doing_multilink - multilink_master - idle_time_limit - link_connect_time - max_connect_time - link_stats - ipparam - hostname - got_sigterm - got_sigusr2 - got_sighup - session_number - maxoctets - maxoctets_dir - debug - persist - devnam - modem - peer_authname - sync_serial * Update the version number to 2.5.0. * Detect availability of stddef.h and stdarg.h. * Rename some headers: - pppcrypt.c/h to crypto_ms.c/h - ppp-crypto.c/h to crypto.c/h - ppp-crypto-priv.h to crypto-priv.h - chap-new.c/h to chap.c/h * Remove chap-md5.h, crypto-priv.h, eap-tls.h, etc. from the list of header files to be installed. * Provide typedefs for the hook functions. * Provide a typedef for the "phase" variable. * Provide a typedef for the link statistics array. * Remove the option_t typedef. * Rename the following functions by adding a "ppp_" prefix (with the intention that these are a "public" API for use by plugins): - option_error - add_options - int_option, - options_from_file - script_setenv - bad_ip_adrs, - netif_get/set_mtu (renamed to ppp_get/set_mtu) - get_time - timeout - untimeout - safe_fork - sys_close - set_session_number - update_link_stats (renamed to ppp_get_link_stats) - add_notifier (renamed to ppp_add_notify) - remove_notifier (renamed to ppp_del_notify) - generic_[dis]establish_ppp (to ppp_generic_[dis]establish) * Rename ppp_devnam to ppp_devname. * Rename ppp_available() to ppp_check_kernel_support(). * Use unsigned char instead of u_char, unsigned short instead of u_short, uint32_t instead of u_int32_t. * Add const to some declarations * Update comments * Change the interface for notifiers to use an enum to identify which notifier is to be modified. * Provide an API for getting the path to a file, with an enum to identify different types of file. * Link plugins with the -DPLUGIN flag [paulus@ozlabs.org - wrote commit message] Signed-off-by: Eivind Næss <eivnaes@yahoo.com> Signed-off-by: Paul Mackerras <paulus@ozlabs.org>

* Use autoconf/automake to configure and make pppEivind Næss2021-07-201-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change brings in autoconf/automake scripts to configure the ppp project. Current change doesn't eliminate the previous build system, but the new script autogen.sh will overwrite configure, and generate the basic Makefile.in and Makefile files. Features can now be enabled by command line: * Microsoft Extensions, - MSCHAP - MPPE - MS LAN Manager support * IPXCP protocol * CBCP protocol * PAM support * EAP-TLS support * EAP-SRP support * Max session lifetime by byte count * Plugins * Packet activity filter support * Multilink * IPv6 support Control linkage with * OpenSSL (-lssl -lcrypto) * systemd (-lsystemd) * libatm (-latm) * libsrp (-lsrp) * pam (-lpam) Also, the configure script is made sensitive to features of OpenSSL. Like the presence or absence of DES, SHA, MD4 and MD5 crypto support. In the cases where either of these are missing, the support will be directly compiled into pppd and plugins. In addition, package maintainers can now control the installation paths with standard --prefix=, or --localstatedir=, or --sysconfdir= to configure. On top of that, they can now control the following directories: * runtime directory w/--with-runtime-dir * logfile directory w/--with-logfile-dir * plugin directory w/--with-plugin-dir In the case where automake isn't the right solution, namely: SunOS kernel module build, the original Makefile infrastructure is preserved and reused. Care was taken to only cosmetically touchup the source files in this change. This means: * Insert HAVE_CONFIG_H and include config.h in all .c files. * Change HAS_SHADOW to HAVE_SHADOW_H * Change HAVE_LOGWTMP to HAVE_UTMP_H * Introduce HAVE_CRYPT_H into the source code where appropriate * Added ifdef MPPE where appropriate * USE_SRP required a few changes as it didn't compile * Touchup some compile warning in pppstats directory on SunOS Introduced a new pppdconf.h file that exports the appropriate defines to a module that wants to provide a module that pppd can dynamically load. This will define/undef features like MPPE, CHAPMS such that the project doesn't have to guess what features pppd is compiled with. Signed-off-by: Eivind Næss <eivnaes@yahoo.com>
* Convert to ANSI CPaul Mackerras2020-12-291-30/+22
| | | | | | | | | | | | | | | This gets rid of the __P and __V macros that were used so that the code was in theory compilable by a K&R C compiler, and converts the function definitions to ANSI C style. In fact there were already quite a few function definitions in the ANSI C style, so it would not have been compilable by a K&R C compiler in fact. The Solaris and BSD kernel code modules have had __P removed but the function definitions have not been converted. There are some other minor changes here to remove warnings.

* Update copyrights. The new CMU copyright notice is from CMU and nowPaul Mackerras2002-12-041-14/+37
| | | | | | | | | explicitly allows modifications. I have an acknowledgement from ANU that the work I have done on pppd belongs to me and not to ANU, so I have changed the ANU copyright notices to reflect this. I have emails from Pedro Roque Marques, Tommi Komulainen and Eric Rosenquist giving me permission to change their copyright notices to be similar to the CMU notice.
