Re: Capsicum project: Ideas needed
FWIW; I would think ftpd, which may require an update too, would be a classical candidate. Perhaps also telnetd. I recall sendmail calls bin/sh for some things and there is an option for a restricted shell (rsh), so supporting a shell would help sendmail too. And then some stuff like ipfw is never too security aware. However for those of us not capsicum-aware it's difficult to say if using jails would be better or more practical. cheers, Pedro. ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org

Re: [RFC] Replacing our regex implementation
Hello; Thanks Gabor for this cool project! --- On Sun, 5/8/11, Gabor Kovesdan ga...@kovesdan.org wrote: ... - It doesn't provide the REG_STARTEND macro, which is our non-POSIX extension. Still, it is useful and easy to implement so it is not a problem either. Our sed requires REG_STARTEND (the illumos guys noted so when they ported our sed). While on this you should also look at bin/153257 and check if TRE supports the sysv legacy delimiters. FWIW, the now defunct lang/gpc used those delimiters to distinguish between our sed and GNU sed. There are still more than 20 ports that depend on gsed. Now I'm working on this little feature and on building a libc with TRE. After that I'll publish a patch for testing and will also ask portmgr to run it on the cluster. It may be interesting, although unnecessarily risky, to see if diff can also use libtre (it uses GNU regex now), but you will probably want to see this as a future step. (NEVERMIND.. you explained this right ahead ;) ) 3, Adding support for GNU-specific permissive regex syntax GNU grep accepts regexes that are invalid in POSIX, like [a|]. This is necessary for grep and diff in the base system. If we don't have them we can never trow out the GNU regex implementation. However, we should not make them default, so I'm thinking of implementing them somewhere else, e.g. in the previously mentioned library. So far, these are the plans, please comments if you have something in your mind about it. Sounds good!

Hi; From http://blogs.sun.com/bonwick/date/200512 At this writing, SEEK_HOLE and SEEK_DATA are Solaris-specific. I encourage (implore? beg?) other operating systems to adopt these lseek(2) extensions verbatim (100% tax-free) so that sparse file navigation becomes a ubiquitous feature that every backup and archiving program can rely on.

OpenWatcom [Fwd: Re: OW on FreeBSD]
Hi; The OpenWatcom on FreeBSD project is one day old but it has advanced greatly(see attached message for current status). FreeBSD experts are welcome. cheers, Pedro. ---BeginMessage--- Okay, I've done some tweaks to the source code so that some of it builds on FreeBSD. Note that currently the build thinks it's targeting Linux, which will need to be fixed. Most of the tools don't really care as long as it's some sort of UNIX, but some do. There are two different ways to build: one uses the build.sh script and the other uses boot.sh. I would suggest concentrating on the latter. The boot build uses exclusively the native compiler and builds wmake, wlink, wdis, debugger, profiler, vi, and a few other odds and ends. Right now the rough status is: - wmake builds and appears to work without any problems - wlink builds and partially works but crashes in some situations - wdis builds and works on some objects but not others, apparently because of some ELF reloc type not seen previously - debugger user interface does not build due to Linux-specific ioctls which need replacing with BSD equivalents - trap file does not build because Linux-specific ptrace stuff needs to be modified - profiler doesn't build either for similar reasons - vi builds but crashes at startup because of insufficient error checking; the real problem is that a build ncurses it uses is configured for Linux and fails to init on FreeBSD The regular build manages to compile wasm and wcc386, both apparently functional (after I fixed a GCC-specific problem in wcc386). It seems likely that both could be used as cross-compilers as long as wlink works (which it doesn't quite appear to). Anyway I'm no UNIX expert and I've seen FreeBSD for the first time yesterday, so now some real FreeBSD expertise is needed. IMO the best course of action is to port the debugger first, because that has proven extremely useful on Linux. I would also like to have the Watcom vi available, just because I can use the exact same editor on Windows, DOS, OS/2, and Linux (the failing console support stuff is shared by vi, debugger, profiler, and one or two other tools). Since FreeBSD uses ELF+DWARF as far as I can tell, there should be little work needed on the file format support, just the OS debugging interface. The other line of work is adding FreeBSD support to the Watcom clib runtime; I expect this should not be terribly difficult for someone familiar with FreeBSD internals if the Linux clib is used as a starting point. In general, it may be helpful to have a Linux box handy for comparison, because all this works (or at least should work) on Linux.

FYI: NetBSD mmap Improvements
taken from wine HQ: http://www.winehq.com/?issue=186#NetBSD mmap Improvements On NetBSD (upcoming 1.6.2, and 1.7/2.0-current), there is a new extension flag MAP_TRYFIXED that essentially simulates current Linux mmap behavior: try the mmap() hint first, without clobbering mapped pages, even if the hint falls within traditionally protected malloc heap space. If the fixed mapping fails, the block is still mapped at a relocated address, as if mmap were called with no flags set. With this patch, mmapping PE files on NetBSD becomes an order of magnitude faster, as the vfork()-and-mincore() silly walk is avoided altogether. I've implemented the patch as forward-looking, allowing other platforms to add MAP_TRYFIXED to gain the same benefit. (This mmap flag name does not appear to be used in any divergent fashion on any other platform, per my research when picking the flag's name.) __ Do you Yahoo!? Yahoo!

Hi; I wanted to bring this up a little later but since there is a somewhat related thread I thought I might as well bring this now. Our default PPPd is extremely outdated. The version in the distribution is a patched-up version of Paul's PPP 2.3.5 which is maintained now at http://dp.samba.org/ppp/. Version 2.3.5 is obsoleted and the latest version doesn't support *BSD. The people from Debian's GNU FreeBSD project have kindly updated this pppd and submitted their changes under a BSD license.

New version of ficl (the core of our bootforth)
I was going to look at ficl-3.03 (our boot code includes 3.02) when I found this claim about the new ficl-4: Ficl 4.0 is a major change for Ficl. Ficl 4.0 is smaller, faster, more powerful, and easier to use than ever before. (Or your money back!) Ficl 4.0 features a major engine rewrite. Previous versions of Ficl stored compiled words as an array of pointers to data structure; Ficl 4.0 adds instructions, and changes over to mostly using a switch-threaded model. The result? Ficl 4.0 is approximately three times as fast as Ficl 3.03. Ficl 4.0 also adds the ability to store the softcore words as LZ77 compressed text.

Problems with international keymaps
Hi guys; I submitted the first latin-american keymap ages ago, and it looks like I'm the only user because I recently have had some problems with it and no one seems to have complained at all !! Anyways, the keymap configuration is done differently today. /stand/sysinstall doesn't seem to use the keymaps files it used before.. it can't find them but it does change the keymap. Where do I permanently hack some keys to get it working correctly? cheers, Pedro. __ Yahoo!

RE: Disk scheduling in FreeBSD

The author of the implementation has also stated in an e-mail to me that he is happy for a BSD-based production-ready derivative to be produced based on his code. The author can do this no doubt.

idea from NetBSD: signal trampoline on libc ?
Hi; I was reading an interview about IRIX binary compatibility on NetBSD, and it looks like they learned a few tricks. This article gets into their native implementation of signals: http://www.onlamp.com/pub/a/bsd/2002/10/10/irix.html At the end of the article Emmanuel Dreyfus mentions: One other interesting thing to note is that since that code was written, Jason Thorpe implemented signal trampolines provided by libc for NetBSD native processes, thus adopting the same scheme IRIX used. The libc provided signal trampoline was adopted in NetBSD because it removes the need to execute code on the stack. Memory pages mapped on the stack can therefore be made non executable (the Memory Management Unit of all modern CPU are able to enforce such rules), and we are able to fix a whole class of security problems. With a non executable stack, it is not possible anymore to exploit a buffer overflow on a local variable by executing some user-supplied code stored on the stack. A drastic change that maybe we should consider? cheers, Pedro. __ Yahoo!

BEWARE: I have never done this, but I probably have a reasonable guess since I wrote the basic "crosskit" ports we carry. Specifically, I need to know: 1. Exactly what FreeBSD-specific things need to be done to a GCC-2.95.2 compilation system to get cross builds to work? Take a look at Jerry Hicks' crossm68k ports, there is everything you need to start with a cross binutils and a crossgcc. You should only have to change the TARGET, but it would be good to check the crossgcc FAQ at cygnus, JIC there is something special about the powerpc crosscompiler. a. What headers should be used? (Not newlib, right?) b. What as and ld should be used. c. What kind of abi options are necessary? Like stack frames, -fwhatevers, etc... d. etc WRT (b) the crossbinutils will produce the as and ld you need. There are two possible paths: 1) building FreeBSD from the start (probably the hardest). - Since you are building for an embedded system you don't need any OS on your target. Something like powerpc-elf should work (look in the crossgcc FAQ for the supported targets). - You should then start porting FreeBSD's libc with this compiler; newlib is probably a good reference. - The rest of the userland has to be built, but I wouldn't bet on the resulting kernel booting due to problems while crossbuilding from 32 to 64 bits. 2) Using another target (probably the path used by FreeBSD-Alpha) -If you have access to the platform in question but just want the crossutils to help, you could use the equivalent NetBSD target (powerpc-netbsd-elf ?). -In this case you can also use NetBSD's headers and libraries while you get started, and get the FreeBSD userland (booter, etc) ported. - Eventually you can get a working kernel and some drivers.
