(henryn) Summary: autobuild 20081212 junction not well supported by cofs Initial Comment: http://www.henrynestler.com/colinux/autobuild/devel-20081212/ http://technet.microsoft.com/en-us/sysinternals/bb896768.aspx in windows host: c: cd \ mkdir a junction a d: (something like ln -s d: .\a) in colinux guest: ls /c/ in 0.8.0-20080924: drwxr-xr-x 1 xuefer users 0 Dec 16 12:16 a/ in 0.8.0-20081212: d-w------- 1 xuefer users 0 Dec 16 12:16 a/ ---------------------------------------------------------------------- >Comment By: Henry N. (henryn) Date: 2009-01-04 21:11 Message: I see, the new implementation has to many problems. FILE_BASIC_INFORMATION (used to get file times and attributes) does not work on junction. Under userland NtFileInfo the times are all 0, but the FILE_BASIC_INFORMATION inside a FILE_ALL_INFORMATIONS works. This can check with the tool FileTest.exe from www.sysinternals. From a ntkernel ZwQueryInformationFile (used for cofs) gots wrong date code, and perhaps also wrong flags. The other problems are by Windows opend files, for example C:\pagefile.sys. Such file got an error for 'stat' or 'ls' on cofs, because they can't open for reading attributes. SVN r1145 have reverted now, and commited as SVN r1199. ---------------------------------------------------------------------- Comment By: Henry N.

I will look more, what this special file does. If you have problems, you can disable this new feature with "noattrib" in the Linux mount options, see cofs.txt in your installation or http://colinux.svn.sourceforge.net/viewvc/colinux/branches/devel/doc/cofs Thanks. ---------------------------------------------------------------------- Comment By: Xuefer (xuefer) Date: 2008-12-16 10:33 Message: FYI, SYSTEM account have full access to both c:\a d:\ ---------------------------------------------------------------------- Comment By: Xuefer (xuefer) Date: 2008-12-16 05:49 Message: btw, i'm using same set of kernel modules but different driver linux.sys/vmlinux/colinux-daemon.exe/colinux-ndis-net-daemon.exe ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=622063&aid=2432504&group_id=98788 |
