Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… Hi, I want to manage a privileged service (namely, openvpn) programmatically. I am using Mac OS X 10.4.7. From the shell, I can do either (having previously created the .conf and .plist files). Both methods work flawlessly (well, launchctl gives the mysterious "Workaround Bonjour: Unknown error: 0" message, but it works). I would like to perform the above operations from inside my code. I have read "Performing Privileged Operations With Authorization Services" in Apple's documentation, and I have browsed through AuthSample and MoreAuthSample's code. As a test, I have taken AuthSample code and changed the performOperation() function in authtool.c by adding the following code: /* XXX perform the actual operation here */ pid_t pid; switch(pid = fork()) { case 0: /* Child */ { execl("/opt/local/sbin/openvpn2", "openvpn2", "--daemon", "--config", "/Users/me/Library/openvpn/openvpn.conf", 0); } case -1: /* an error occured */ return kMyAuthorizedCommandInternalError; default: /* Parent */ break; } execl("/bin/launchctl", "launchctl", "load", "/Library/LaunchDaemons/ net.openvpn.plist", 0); The latter method simply does not work. In the console, I get several messages like this: Using the former method, the process starts (as root, correctly), but it does not work. Browsing the logs, it seems that openvpn initialization chokes somewhere, and the routing tables are left incomplete (I get one tap0 entry, while I get three when I run openvpn from the shell). 1) why do the commands from the shell and from the program behave differently? Is there any (possibly trivial) oversight in my code? 2) Is launchd to be preferred over other methods in this case? And is it the way to go in general?

replace libxml2 dynamically

Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… Hello list, Here is my problem: /usr/lib/libxml2.2.dylib (as of Mac OS X 10.4.7) is version 20616 and this is the version used by the Foundation framework. It contains a very annoying bug that may validate invalid documents :-( This bug vanished in later version of libxml2. My own compiled version (20626) of libxml2 is working fine and I need to use this one instead of /usr/lib/libxml2.2.dylib. I don't want to ask users their admin password to mess with /usr/lib/libxml2.2.dylib, so I'd like to use dyld capabilities instead. My libxml2.2.6.26.dylib is compiled to load in my application with the proper install_name: $ otool -L XMLToy XMLToy: @executable_path/../lib/libxml2.2.6.26.dylib (compatibility version 9.0.0, current version 9.26.0) /System/Library/Frameworks/Foundation.framework/Versions/C/ Foundation (compatibility version 300.0.0, current version 567.23.0) /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.1.3) I have checked that my libxml2.2.6.26.dylib is loaded by setting DYLD_PRINT_LIBRARIES, but the system version is used anyway. I'm not very familiar with dyld but I guess it doesn't work because /usr/lib/ libxml2.2.dylib uses two level namespace. Any solution in order Foundation to use my lib instead of the system lib without messing with the /usr/lib/libxml2.2.dylib file ? This email sent to site_archiver(a)lists.apple.com

dyld not binding correctly?

The plugin does the following: void *plib = dlopen( "OLDLIB.dylib", RTLD_LOCAL ); and then later I want to load a new library that has some of the same symbol names but different functionality: void *plib = dlopen( "NEWLIB.dylib", RTLD_LOCAL ); when I set DYLD_PRINT_BINDINGS dyld is binding symbols from OLDLIB.dylib: dyld: loaded: /Users/me/Application Support//Updater/NEWLIB.dylib, cpu-sub-type: 3 dyld: bind: NEWLIB.dylib:0x0f105148 = OLDLIB.dylib:__ZTI8VUpdater, *0x0f105148 = 0x0d260dc0 dyld: bind: NEWLIB.dylib:0x0f105108 = OLDLIB.dylib:__ZTI17VTransferListener, *0x0f105108 = 0x0d260600 dyld: bind: NEWLIB.dylib:0x0f1050a8 = OLDLIB.dylib:__ZTI17VTransferListener, *0x0f1050a8 = 0x0d260600 dyld: bind: NEWLIB.dylib:0x0f105080 = OLDLIB.dylib:__ZTV17VTransferListener, *0x0f105080 = 0x0d2606a0 + 12 dyld: bind: NEWLIB.dylib:0x0f105064 = OLDLIB.dylib:__ZTS7VObject, *0x0f105064 = 0x0d216396 Running 'otool -h' on both libraries shows that twolevel_namespace is enabled. I also see the above symbols are indeed in NEWLIB.dylib. Anyone have any ideas why the binding is incorrect? _______________________________________________ Do not post admin requests to the list.

I've updated to darwinbuild 0.7.2, this seems to have resolved the boot.txt file issue however, the darwinmaster script has some syntax errors and things still aren't working as expected/intended. It doesn't generate a system on the image, it has a problem creating the netinfo db (resolved by adding a mkdir line) and it has an issue with kextcache (mkext/mach_kernel creation) which I'm not familar with but I'm willing to put together a package if I can get some assistance with creating a working model to base the works on and I'll have source for the mkisofs binary for inclusion by the end of the weekend. -Ben -- Dale This email sent to site_archiver(a)lists.apple.com
