Sudo porting hints ================== Before trying to port sudo to a new architecture, please join the sudo-workers mailing list (see the README file) and ask if anyone has a port working or in-progress. Sudo should be fairly easy to port. Since it uses a configure script, most of the work should be done for you. If your OS is an SVR4 derivative (or some approximation thereof), it may be sufficient to tell configure you are runnng SVR4, something like: configure foo-bar-sysv4 where foo is the hardware architecture and bar is the vendor. A possible pitfall is getdtablesize(2) which is used to get the maximum number of open files the process can have. If an OS has the POSIX sysconf(2) it will be used instead of getdtablesize(2). ulimit(2) or getrlimit(2) can also be used on some OS's. If all else fails you can use the value of NOFILE in <sys/param.h>. Sudo tries to clear the environment of dangerous envariables like LD_* to prevent shared library spoofing. If you are porting sudo to a new OS that has shared libraries you'll want to mask out the variables that allow one to change the shared library path. See badenv_table() in sudo.c to see how this is done for various OS's. It is possible that on a really weird system, tgetpass() may not compile. (The most common cause for this is that the "fd_set" type is not defined in a place that sudo expects it to be. If you can find the header file where "fd_set" is typedef'd, have tgetpass.c include it and send in a bug report.) Alternately, tgetpass.c may compile but not work (nothing happens at the Password: prompt). It is possible that your C library contains a broken or unusable crypt() function--try linking with -lcrypt if that exists. Another possibility is that select() is not fully functional; running configure with --with-password-timeout=0 will disable the use of select(). If you are trying to port to a system without standard Berkeley networking you may find that interfaces.c will not compile. This is most likely on OS's with STREAMS-based networking. It should be possible to make it work by modifying the ISC streams support (see the _ISC #ifdef's). However, if you don't care about ip address and network address support, you can just run configure with the --without-interfaces flag to get a do-nothing load_interfaces() stub function. If you port sudo to a new architecture, please send the output of "configure", the config.log file and your changes to: sudo@courtesan.com If you are unable to get sudo working, and you are willing to give me an account on a machine, send mail to sudo@courtesan.com. Note, however, that I can't make any promises.
