[Bug 10974] New: wine prefers loopback devices over regular files
http://bugs.winehq.org/show_bug.cgi?id=10974 Summary: wine prefers loopback devices over regular files Product: Wine Version: CVS/GIT Platform: Other OS/Version: other Status: UNCONFIRMED Severity: normal Priority: P2 Component: wine-kernel AssignedTo: wine-bugs(a)winehq.org ReportedBy: rmh(a)aybabtu.com Created an attachment (id=9920) --> (http://bugs.winehq.org/attachment.cgi?id=9920) fix loopback handling When using a loopback device as a wine drive, wine will prefer to use the loopback device (e.g. /dev/loop0) for volume access rather than the regular file it's based on (e.g. ~/foo.iso).
From dlls/ntdll/directory.c:
else if (!stat( entry->mnt_fsname, &st ) && S_ISREG(st.st_mode)) { /* if device is a regular file check for a loop mount */ if ((device = strstr( entry->mnt_opts, "loop=" ))) { char *p = strchr( device + 5, ',' ); if (p) *p = 0; return device + 5; } } I'm not sure if this has any advantage, but it has a big inconvenient. It's almost certain that /dev/loop0 is owned by root and not world-readable, and it's also mostly certain that wine isn't being run as root. If the image is user-owned, by using the loop device we lose the ability to read it. This typicaly causes breakage that is difficult to figure out. For example, see http://appdb.winehq.org/objectManager.php?sClass=version&iId=727&iTestingId=... Note: I'm filing this separate from bug 10957 because it's an unrelated issue. The patch I'm attaching here collides with the one I sent for bug 10957, but takes both situations into account. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.

Please retest in current git. If the bug is still present in today's wine, but was not present in some earlier version of wine, please update version field to earliest known version of wine that had the bug.

The real bug is in mount, it should fix the permissions of the device when mounting it. -- 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.
