[Bug 57391] New: FSCTL_DISMOUNT_VOLUME does not work on drives with spaces in path
https://bugs.winehq.org/show_bug.cgi?id=57391 Bug ID: 57391 Summary: FSCTL_DISMOUNT_VOLUME does not work on drives with spaces in path Product: Wine Version: 9.20 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)winehq.org Reporter: toadking(a)toadking.com Distribution: --- After investigating, it looks like the FSCTL_DISMOUNT_VOLUME ioctl is implemented by manually calling `umount` on the volume's mount path, but the program is invoked using `system` instead of via other methods. This means spaces in the volume path are not handled correctly and the volume is never actually unmounted. Reproduction: * Insert a DVD/Blu-ray and mount it at a path including a space. * Run `wine eject <drive letter>: Results: Drive is not ejected Expected: Drive is rejected Attached are strace calls on two paths (one with a space, one without) showing the issue. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

Not sure how it would work, without admin rights. Anyways, I think I located the place, and added quotation, does this fix the issue? -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=57391 --- Comment #4 from Michael Lelli <toadking(a)toadking.com> --- Created attachment 77372 --> https://bugs.winehq.org/attachment.cgi?id=77372 fork/exec patch The quotes fix the issue partially, but the error would still appear if the mount path has quotation marks in it. Not common but they are allowed. I made an alternative patch that does a fork/exec to launch the program instead of system. That way there doesn't need to be any shell escaping. It works on my system with a disc mounted with udisks that includes a space in its label (which is how I hit the bug in the first place). strace after my patch: [pid 337484] clone(child_stack=NULL, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLDstrace: Process 337485 attached , child_tidptr=0xf682a4e8) = 337485 [pid 337485] execve("/usr/local/sbin/umount", ["umount", "/run/media/michael/Untitled Project"], 0xffd258c4 /* 91 vars */) = -1 ENOENT (No such file or directory) [pid 337485] execve("/usr/local/bin/umount", ["umount", "/run/media/michael/Untitled Project"], 0xffd258c4 /* 91 vars */) = -1 ENOENT (No such file or directory) [pid 337485] execve("/usr/bin/umount", ["umount", "/run/media/michael/Untitled Project"], 0xffd258c4 /* 91 vars */) = 0 -- Do not reply to this email, post in Bugzilla using the above URL to reply.

Not sure why "system" as used to begin with, but your approach seems sensible. Will you create a MR for that? -- Do not reply to this email, post in Bugzilla using the above URL to reply.
