    Hello, I'm also trying to enable 16-bit support for Wine in the vanilla Arch Linux distro. I have followed the instructions to reconfigure the kernel 4.18.14 setting up CONFIGMODIFYLDTSYSCALL=y. After that I was able to recompile the kernel. However the file 'ldt16' doesn't exist in the '/proc/sys/abi/' path. Executing 'zcat /proc/config.gz grep 'MODIFYLDT' retrieves 'CONFIGMODIFYLDTSYSCALL=y'.

    Would you kindly point me in the right direction in order to have the ldt16 file produced? I have gone through the wiki page for the kernel recompilation, and several articles in the Internet with no luck. Thank you in advance. Neo Last edited by NeoLG (2018-10-24 07:46:21). Thank you Progandy for the additional information and clarifying there's no LDT16 file and therefore 'echo 1 /proc/sys/abi/ldt16 ' wouldn't apply. I definitely missed activating 'CONFIGX8616BIT' on the kernel configuration phase. I would like to add for the benefit of other newcomers that in the screen that allows to configure the kernel; the F8 key (I believe is the NConfig utility) can be used to search for the 'actual wording' associated to a KERNEL FLAG needed to re-enable 16-bit support for Wine.

    Another observation is that CONFIGX8616BIT only became available after activating/checking CONFIGMODIFYLDTSYSCALL; and that CONFIGX86ESPFIX64 is indirectly activated by other kernel flags. Thanks again for the help Neo.

    In this=20 case, the problem is that you have /usr/include/asm symlinked to your kernel's include/asm-i386 directory, which is the wrong setup. However your solution should not give any problem. Kernel-Modules are usually compiled against the sources in either /usr/src/linux or /lib/modules//build.

    Take a look at the nvidia-kernel ebuild or other ebuilds that build kernel modules. It would be fatal to compile them against the headers in /usr/include.

    Hi all, I applied Blaisorblade's host-skas3-2.6.9-v7.patch, and it breaks the fglrx graphics driver from ATI1. This is with Debian kernel 2.6.9, but I believe it applies to vanilla kernels also.

Yes, the compilation error is in compiling the fglrx module. In this case, the problem is that you have /usr/include/asm symlinked to your kernel's include/asm-i386 directory, No, I don't, but I use Debian's make-kpkg which probably uses header files from the kernel tree. This is the normal method of building kernels on Debian, though.

    I might add that I tried to fix the problem directly in the fglrx module, but it doesn't seem to work. It really must use the name modifyldt in the macro, and this conflicts with the UML patch.

    Yes, the compilation error is in compiling the fglrx module. Ok, unexpected. In this case, the problem is that you have /usr/include/asm symlinked to your kernel's include/asm-i386 directoryNo, I don't, but I use Debian's make-kpkg which probably uses header files from the kernel tree.

    This is the normal method of building kernels on Debian, though. Well, since it is a kernel module, then it's correct. I might add that I tried to fix the problem directly in the fglrx module, but it doesn't seem to work. It really must use the name modifyldt in the macro Yes, because the name in the macro is used to build the 'NRmodifyldt' , and this conflicts with the UML patch. Ok, this makes me wonder a bit. There is something which may cause conflicts in the UML patch (i.e.

    Renaming modifyldt that way), but it is very.strange. that a kernel module uses the 'syscall' macro to do a syscall with 'int 0x80' while already being in kernelspace.

They're trying to workaround the fact that modifyldt is not exported. Thus they are probably violating the GPL I am under the impression that it is permitted to distribute a binary module, with only the 'loader' under GPL. No, I don't think so.

    The strict GPL interpretation is that you cannot distribute a non-GPL work which links with GPL code. In fact, distributions cannot distribute GPL code linking with XFree 4.4. What you probably see is that NVIDIA modules (and ATI ones too I guess, but I don't know well) have a binary-only part and a source-code part. Linux developers mostly consider binary module to be ok until they are not 'derivative works'. And when a symbol is not exported, many times, it is because kernel developers feel that code using it is a derivative of the kernel.

    Is There A Way To Add/enable Config_modify_ldt_syscall

    In this case, it's maybe different - nobody thought that the sysmodifyldt symbol should have been exported. That said, if somebody asked the question, the answer could be 'No, it must not be exported, because modules using it are derivative works'. On the other side, any userspace program can call the modifyldt syscall. Do you mean that they are actually violating the license, Well, just a rough feeling. I am not a lawyer. or that they are evading the kernel's tainting mechanism?

    I suspect that they want to avoid users getting the message about tainted kernels. No, users will get the message, unless the module declares it self as 'GPL' with a 'MODULELICENSE('GPL') directive in the code, which it should not. If so, then I would like to complain to them, because 1) it is disgusting behaviour and 2) it makes my life more difficult having to take care of their stupid code. For your specific problem, I'm applying your fix to next version of the SKAS patch (which I'm publishing anyway with other work).

    See my other mail. Not that it is a bug of the SKAS patch or of the ATI module alone. For the GPL issue, you should probably ask to LKML (or post a letter to LWN.net about this issue - they could maybe publish it and you'd see the comments) or on slashdot.org (which is actually a discussion forum) - I have read discussions about such issues, but I'm not myself an expert.
