[Bug 20081] New: Add ability to simply call the unix function mknod()
http://bugs.winehq.org/show_bug.cgi?id=20081 Summary: Add ability to simply call the unix function mknod() Product: Wine Version: 1.1.29 Platform: PC URL: http://rh-software.com/ OS/Version: Linux Status: UNCONFIRMED Severity: enhancement Priority: P2 Component: -unknown AssignedTo: wine-bugs(a)winehq.org ReportedBy: ray(a)pobox.co.uk Please can a wine_mknod() function be added that can be loaded in a similar way to wine_get_host_version() that SIV could use ? Currently I am having to do this using code similar to: stprintf( b, TEXT( "/bin/mknod -m %o /dev/cpu/%u/msr c 202 %u" ), m, i, i ); _tsystem( b ); which works, but is not ideal if there is a failure and I should report an error. Having this in ntdll.dll would make things very easy, but I am not sure if this is the appropriate .dll to use, I would be happy to load any .dll. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

Does this functionality exist in Windows?
As Windows does not have mknod type devices obviously not, if it did there would be the mknod() function in the Windows C library that I would have used. I feel this would be a useful facility. You seem to be implying that Wine should only have functions that Windows has, however such functions as wine_get_host_version() are in Wine, but not in Windows, so I don't see why a wine_mknod() is any different. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

It should be my decision as to how my code works. Converting SIV to a winelib app is not worth the effort just so I can call mknod.

I thought the idea of Wine was to allow Windows programs to run WILL on *nix systems. SIV needs to create /dev/cpu/nn/msr devices to do this and I feel Wine should help in doing this. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

Windows apps do not need to know what to do with this call. Wine needs to know what to do with this call. My Windows app does know what to do with this call, others may not. There are lots of Windows calls that many windows apps do not know what to do with.

More or less.

Some of them have notes which indicate that you probably don't want to use mknod, and others indicate that your syntax isn't correct: E.g. Solaris: mknod name b major minor mknod name c major minor mknod name p [...] With the advent of physical device naming, it would be preferable to create a symbolic link to the physical name of the device (in the /devices subtree) rather than using mknod. and BSD: mknod [-F format] name [c | b] major minor mknod [-F format] name [c | b] major unit subunit mknod name [c | b] number Also, on these systems, major number 202 may already be in use by something else; I'm not sure that's what you want. Also, don't some of the /dev pseudo-filesystem options for Linux effectively defeat mknod when it's used? With these considerations in mind, I can't see the need for a wine_mknod() function. Perhaps if you can find an analog in the Windows API, then someone should figure out the "right" way of doing it. But I don't know of such an analog. I concur with the others who are saying you should be writing a winelib app. I'd add the caveat that you probably want to do a ton of sanity checking, if you're relying on direct access to system interfaces under Wine. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

I suspected that different Wine hosts may have different mknod command line requirements and hoped that by using the mknod() function this would be reduced. What I am actually doing is reading MSRs with on Windows I do by calling my Kernel Driver which does an RDMSR instruction. With Wine I can not do this as Wine does not run my driver in Kernel mode and therefore RDMSR can not be used. I could argue that as I can do this on Windows then I should be able to do the same with Wine, but I realise this is never going to possible with Wine, so I needed to find another way. I found on Linux I could do this my reading the type 202 devices, so this is what I do, but these devices need to be created which is why I need to use mknod. As you have pointed out I am going to have to do different things on different Wine hosts which is something I expected and internally my code is designed to make doing this easy and also to allow for not being able to read MSRs at all. When I initially put in the request I felt it was a trivial addition to Wine and could bee no good reason what it would be rejected and I still feel this is the case. Further, as far as I know, i few Wine functions work of some hosts and not others already. Given the hostile response this request has received I am totally losing interest in improving Wine, so will probably simply create a whinelib dll that exports the native functions I wish to use. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

"Normal" Windows applications can run their drivers in kernel mode. Wine does not allow this, so I am trying to work round this. Having a wine_mknod() would help me do this.

I would do this if I was confident I could do this for all Wine hosts, but as been pointed out there are lots of varations in mknod. Given I have only been using Wine for a couple of weeks and have never generated a patch I suspect doing this would currently be tricky for me. On Real Windows I read the MSRs in my kernel mode driver, but on Wine this driver gets run in User Mode. The is the problem I am working around. Were Wine to run my driver in Kernel Mode then I would not need to use mknod() at all, so I have logged http://bugs.winehq.org/show_bug.cgi?id=20098. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
