proto_pptp_setup is responsible for loading the required modules to establish a pptp connection to a foreign peer. The function checks whether all required modules are already loaded, before actually loading them. It seems that the filter being used to accomplish this, is not restrictive enough in some cases. For instance when pptp nat helper modules are present on a system, and already loaded before a pptp connection is enabled. Then the search filter (possibly) returns the following for module=pptp, where actually no matches are expected, resulting in the pptp.ko module not being loaded, thereby failing to establish the pptp connection. # module="pptp" ; grep "$module" /proc/modules nf_nat_pptp 1312 0 - Live 0x86ce7000 nf_conntrack_pptp 3072 1 nf_nat_pptp, Live 0x86cb9000 nf_nat_proto_gre 784 1 nf_nat_pptp, Live 0x86cba000 nf_conntrack_proto_gre 2368 1 nf_conntrack_pptp, Live 0x86cbf000 nf_nat 9792 13 nf_nat_rtsp,nf_nat_tftp,nf_nat_sip,nf_nat_pptp,nf_nat_h323,nf_nat_proto_gre,nf_nat_amanda,nf_nat_irc,nf_nat_ftp,ipt_REDIRECT,ipt_NETMAP,ipt_MASQUERADE,iptable_nat, Live 0x86ca8000 nf_conntrack 37264 31 nf_nat_rtsp,nf_conntrack_rtsp,nf_nat_tftp,nf_conntrack_tftp,nf_nat_snmp_basic,nf_conntrack_snmp,nf_nat_sip,nf_conntrack_sip,nf_nat_pptp,nf_conntrack_pptp,nf_nat_h323,nf_conntrack_h323,nf_conntrack_proto_gre,nf_nat_amanda,nf_conntrack_amanda,nf_conntrack_broadcast,nf_nat_irc,nf_conntrack_irc,nf_nat_ftp,nf_conntrack_ftp,ipt_MASQUERADE,iptable_nat,nf_nat,xt_helper,xt_connmark,xt_connbytes,xt_conntrack,xt_CT,xt_NOTRACK,xt_state,nf_conntrack_ipv4, Live 0x86c90000 The search filter can be made more accurate/restrictive, by requiring the occurance of the exact name of the module at the beginning of a line in /proc/modules. # module="pptp" ; grep "^$module " /proc/modules pptp 13296 2 - Live 0x86e80000 Signed-off-by: Tijs Van Buggenhout <tvb@able.be> SVN-Revision: 38358
This is the buildsystem for the OpenWrt Linux distribution. Please use "make menuconfig" to configure your appreciated configuration for the toolchain and firmware. You need to have installed gcc, binutils, bzip2, flex, python, perl make, find, grep, diff, unzip, gawk, getopt, libz-dev and libc headers. Run "./scripts/feeds update -a" to get all the latest package definitions defined in feeds.conf / feeds.conf.default respectively and "./scripts/feeds install -a" to install symlinks of all of them into package/feeds/. Use "make menuconfig" to configure your image. Simply running "make" will build your firmware. It will download all sources, build the cross-compile toolchain, the kernel and all choosen applications. You can use "scripts/flashing/flash.sh" for remotely updating your embedded system via tftp. The OpenWrt system is documented in docs/. You will need a LaTeX distribution and the tex4ht package to build the documentation. Type "make -C docs/" to build it. To build your own firmware you need to have access to a Linux, BSD or MacOSX system (case-sensitive filesystem required). Cygwin will not be supported because of the lack of case sensitiveness in the file system. Sunshine! Your OpenWrt Project http://openwrt.org
