Description xiagao 2023-02-21 07:28:54 UTC 
Description of problem:
After enabling case-insensitive for virtiofs service, md5sum or notepad cmd still fail to open the file with uppercase/lowercase letter.


Version-Release number of selected component (if applicable):
qemu-kvm-7.2.0-8.el9.x86_64
kernel-5.14.0-252.el9.x86_64
edk2-ovmf-20221207gitfff6d81270b5-5.el9.noarch
virtio-win-prewhql-0.1-234

How reproducible:
100%

Steps to Reproduce:
1.start virtiofs daemon
# /usr/libexec/virtiofsd --shared-dir /home/test --socket-path /tmp/sock1 -d

2.boot up win2022 guest
     -chardev socket,id=char_virtiofs_fs,path=/tmp/sock1 \
     -device vhost-user-fs-pci,id=vufs_virtiofs_fs,chardev=char_virtiofs_fs,tag=myfs,queue-size=1024,bus=pcie-root-port-3,addr=0x0 \

3.start virtiofs service and enable case-insensitive
z:\>sc create VirtioFsSvc binpath=virtiofs.exe start=auto depend="WinFsp.Launcher/VirtioFsDrv" DisplayName="Virtio FS Service"
z:\>reg add HKLM\Software\VirtIO-FS /v CaseInsensitive /d 1 /t REG_DWORD

4. reboot guest
5. login guest and create a file on the shared dir, and create a file, try to get md5 checksum for the file.
M:\>type file.txt
hello
M:\>type FILE.txt
"hello"
M:\>md5sum file.txt
c4a246e402c50cd67617e59affd536b1 *file.txt
M:\>md5sum FILE.txt
No such file: FILE.txt

5. Try to repeat step 4 on the file on C: volume.
C:\>md5sum test.txt              
6dd4566eb245627b49f3abb7e4502dd6 *test.txt

C:\>md5sum TEST.txt
6dd4566eb245627b49f3abb7e4502dd6 *test.txt


Actual results:
After step4, md5sum can't get the file with uppercase letter, it's sensitive to uppercase and lowercase letters.

Expected results:
For virtiofs volume,md5sum is insensitive with uppercase and lowercase letters as it does in C:


Additional info:
Notepad, type, dir, etc are insensitive with case letter.
Comment 1 Viktor Prutyanov 2023-02-21 16:29:02 UTC 
Hi,

what kind of md5sum are you using? My md5sum is working in the case-insensitive way.

Z:\>md5sum --version
md5sum (GNU coreutils) 8.32

Z:\>cat file.txt
hello

Z:\>cat File.txt
hello

Z:\>md5sum file.txt
6dd4566eb245627b49f3abb7e4502dd6 *file.txt

Z:\>md5sum FILE.TXT
6dd4566eb245627b49f3abb7e4502dd6 *FILE.TXT
Comment 2 xiagao 2023-02-23 06:31:32 UTC 
Yes, the md5sum version is too old on my side.
I will try to use the latest one to have a test.
Comment 3 xiagao 2023-02-27 02:26:48 UTC 
M:\>c:\"program files"\git\usr\bin\md5sum.exe --version
md5sum (GNU coreutils) 8.32


M:\>c:\"program files"\git\usr\bin\md5sum.exe TEST
5c9597f3c8245907ea71a89d9d39d08e *TEST

It works with the newer md5sum, so I will close this bug.

Btw, for the md5sum tool for windows, I searched online for times, but I'm only able to get it from the git bash. 
Hi Viktor, do you have a better way to get it? Thanks in advance.
Comment 4 Yvugenfi@redhat.com 2023-02-27 08:09:59 UTC 
Keeping open in order to investigate root cause with the old version in order not to skip the bug on our side.
Comment 6 Viktor Prutyanov 2023-03-04 20:18:12 UTC 
Hi Xiaoling,

What was the old version of md5sum that you used? How to obtain it?

The version is 1.22, it's an older one and I don't know how to obtain it, it existed in our test tool for a long time.
C:\>md5sum.exe --version
md5sum (PCP patchlevel 2) (GNU textutils) 1.22
Comment 10 Viktor Prutyanov 2023-03-16 13:56:25 UTC 
Old md5sum also works somehow:

Z:\>echo hello > file.txt

Z:\>type file.txt
hello

Z:\>type FILE.txt
hello

Z:\>md5sum file.txt FILE.txt
6dd4566eb245627b49f3abb7e4502dd6 *file.txt
6dd4566eb245627b49f3abb7e4502dd6 *FILE.txt

Z:\>C:\md5sum.exe file.txt FILE.txt
6dd4566eb245627b49f3abb7e4502dd6 *file.txt
6dd4566eb245627b49f3abb7e4502dd6 *FILE.txt

Z:\>C:\md5sum.exe --version
md5sum (PCP patchlevel 2) (GNU textutils) 1.22

Yan, Viktor, do you plan to have this bug fixed in 9.2.Z? And could you help update the 'Internal Target Release' field?
Thanks.

Hi, this bug is still under investigation. No plans for Z stream.
Comment 14 Viktor Prutyanov 2023-07-02 18:17:11 UTC 
Hi Xiaoling,

Could you please reproduce the issue on latest virtio-win by running virtiofs from command-line with '-i' argument?

Sure, I have the result with prewhql-238 version.
Unfortunately, it still doesn't work.

Comment 16 Viktor Prutyanov 2023-07-03 07:59:34 UTC 
Could you please enable debug logging (-d -1 -D ...), perform the same things and share the log with me?
Comment 17 Viktor Prutyanov 2023-07-03 08:35:31 UTC 
Also, what is WinFsp version?

It's 1.12.22339
Comment 20 Viktor Prutyanov 2023-07-03 09:43:25 UTC 
I can't reproduce the issue on both Win2019 and Win2022 with WinFsp 1.12.22339, so please share the virtiofs debug logs and daemon logs.

The log is in comment18 for win10 guest, do you want the log for win2019 or win2022?
