dolphin in focal can't delete webdav directories running on focal's apache

[Adam Vodopjan]

[Impact]
WebDAV DELETE operations on directories don't work for the Dolphin file manager, due to not being recognized by Apache. This limits KDE users from managing remote filesystems.

[Workaround]
Some versions of the client may allow overriding the global default user agent.

[Test Case]
0. Create a testing VMs.
    a. Server VMs can be for each targeted Ubuntu release.
        Name these 'davtest-<codename>'
    b. Client VM is Ubuntu focal, and needs to run graphics apps.
1. On server, install Apache configured to provide a directory tree via WebDAV
    a. Create the DAV directory structure
        sudo mkdir -p /var/www/webdav/example/test
        sudo chown -R www-data:www-data /var/www/webdav
    b. Install Apache with DAV
        sudo apt-get install apache2
        sudo a2enmod dav dav_fs
    c. Create /etc/apache2/sites-available/davtest.conf
        <VirtualHost *:80>
            ServerName davtest-<codename>.lxd
            DocumentRoot /var/www/webdav
            ErrorLog ${APACHE_LOG_DIR}/error.log
            CustomLog ${APACHE_LOG_DIR}/access.log combined

            Alias /webdav /var/www/webdav
            <Directory /var/www/webdav>
                DAV On
                AllowOverride None
                Require all granted
            </Directory>
        </VirtualHost>
    d. Enable the new configuration and restart apache2
        sudo a2ensite davtest.conf
        sudo a2dissite 000-default.conf
        sudo systemctl restart apache2
2. On client, install Dolphin (requires the core KDE system as well)
    a. sudo apt-get install dolphin
    b. dolphin
    c. In dolphin, press C-l and enter "webdav://davtest-<codename>"
    d. Create some files and dirs
    e. Verify can delete files
    f. Attempt to delete directories, then refresh (F5) and check if still visible.
    g. Check on server whether directory was actually deleted

An alternative to #2 uses curl instead of Dolphin:
    a. curl -I -X DELETE -A 'prefix dolphin/' http://davtest-<codename>.lxd/example/test
        This will display a "Moved Permanent" redirect warning (which will make dolphin fail).
        In the user agent, 'prefix' is a placeholder and any text can be used. E.g. 'xyz dolphin'.
    b. Adding a trailing / will make it avoid the redirect. I.e.:
        curl -I -X DELETE -A 'prefix dolphin/21.12.3' http://davtest-<codename>.lxd/example/test/
    c. Try also with 'prefix Konqueror/5' or 'prefix Konqueror/4'. The former may not work but the latter should.

[Where Problems Could Occur]
The fix only touches the package's default DAV config file, so things to watch for would be misbehaviors with configuration settings when DAV is installed. For instance, during system upgrades, if customized httpd-dav.conf files start seeing problems then it might relate to this.

Since the fix is particular to KDE, if any issues particular to KDE applications operating against Apache2 servers might be relevant.

[Other Info]
Some versions of Dolphin apparently use the "Konqueror/5" user agent, while others use "dolphin". This SRU adds supports for both, to ensure the issue is fully resolved.

[Original Report]
/etc/apache2/mods-available/setenvif.conf from the apache2 package has this:

    BrowserMatch " Konqueror/4" redirect-carefully

While dolphin is Konqueror/5 in focal. Trying to delete a directory on webdav dolphin just gets a http 301 redirect.

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
Description: Ubuntu 20.04.2 LTS
Release: 20.04

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
apache2:
  Installed: 2.4.41-4ubuntu3.1

3) What you expected to happen
Dolphin should be able to remove directories over webdav

4) What happened instead
Apache issues a redirect from prefix/dir to prefix/dir/

    127.0.0.1 - user1 [07/May/2021:02:19:53 +0000] "DELETE /webdav/test HTTP/1.1" 301 578 "-" "Mozilla/5.0 (X11; Linux x86_64) KHTML/5.68.0 (like Gecko) Konqueror/5 KIO/5.68"

Dolphin doesn't follow the redirect hence nothing happens.

[Paride Legovini (paride)]

Hello Ross and thanks for this bug report. Did you actually verify that adding a

  BrowserMatch " Konqueror/5" redirect-carefully

line to setenvif.conf resolves the issue?

Anyway the file belongs to the packaging and not to the upstream source, so the fix belongs to Ubuntu. Waiting for your feedback on the " Konqueror/5" test I'm marking this bug report as Incomplete. Please change its status back to New after commenting back and we'll look at it again. Thanks!

[Adam Vodopjan (grozzly)]

Yes,

BrowserMatch " Konqueror/5" redirect-carefully

does fix the bug.

[Adam Vodopjan (grozzly)]

While you're at it: kinda the same happens in jammy (as of 22.04.2). This time the user agent for dolphin is:

    Mozilla/5.0 (X11; Linux x86_64) KIO/5.92 dolphin/21.12.3

With stock apache conf when trying to delete a dir over webdav, it results in a 301 redirect: '"DELETE /webdav/test HTTP/1.1" 301 578' => /webdav/test/

With such custom line in setenvif.conf it works as supposed:

    BrowserMatch " dolphin/" redirect-carefully

[Michał Małoszewski (michal-maloszewski99)]

Thanks for update :)

[Michał Małoszewski (michal-maloszewski99)]

@Adam

Given the file belongs to the packaging and not to the upstream source, we should expect the Delta to be a long-term one.
That, combined with the fact that this bug is present in Debian too, and Ubuntu currently doesn't make any changes over the Debian package --> this bug would be best fixed directly in Debian, and then Ubuntu will pick up the fix automatically.

So the best way is to file a Debian bug report.

[Sergio Durigan Junior (sergiodj)]

Michal,

This bug seems to affect Focal/Jammy, and therefore the fix needs to be done in Ubuntu. You also need to check if the issue is still present in Mantic, or if it has already been fixed there.

[Christian Ehrhardt (paelzer)]

Hey you two,
thanks for picking this one up after such a long time.

@Michal - while you are right that the particular config file does not have any changes, the reasoning for "Ubuntu currently doesn't make any changes over the Debian" is usually for auto-sync and apache clearly has changes in general (just not in that file). Therefore that is not a problem.

@Sergio - agreed, for an SRU this needs a test case anyway, which means Michal can start in Mantic and testing it through all releases.

@All
While looking at it quickly I found that there are two files with such a config

From upstream we have this for DAV related usage in
apache2-doc: /usr/share/doc/apache2/examples/apache2/extra/httpd-dav.conf

$ cat docs/conf/extra/httpd-dav.conf.in
...
BrowserMatch "Microsoft Data Access Internet Publishing Provider" redirect-carefully
BrowserMatch "MS FrontPage" redirect-carefully
BrowserMatch "^WebDrive" redirect-carefully
BrowserMatch "^WebDAVFS/1.[01234]" redirect-carefully
BrowserMatch "^gnome-vfs/1.0" redirect-carefully
BrowserMatch "^XML Spy" redirect-carefully
BrowserMatch "^Dreamweaver-WebDAV-SCM1" redirect-carefully
BrowserMatch " Konqueror/4" redirect-carefully

Then the file we got asked here is in
apache2: /etc/apache2/mods-available/setenvif.conf

$ cat /etc/apache2/mods-available/setenvif.conf
BrowserMatch "Microsoft Data Access Internet Publishing Provider" redirect-carefully
BrowserMatch "MS FrontPage" redirect-carefully
BrowserMatch "^WebDrive" redirect-carefully
BrowserMatch "^WebDAVFS/1\.[012]" redirect-carefully
BrowserMatch "^gnome-vfs/1\.0" redirect-carefully
BrowserMatch "^gvfs/1" redirect-carefully
BrowserMatch "^XML Spy" redirect-carefully
BrowserMatch "^Dreamweaver-WebDAV-SCM1" redirect-carefully
BrowserMatch " Konqueror/4" redirect-carefull

This is already diverging.
The latter is Ubuntu/Debian delta over upstream.

Now those two are out of sync a lot IMHO
1. [1] fixed escaping, but not upstream?
2. gvfs [2] was added in Debian but never upstream AFAICS
3. Konquerer/4 was added upstream [3] and in Debian [4]

Now here in the bug we have the report of
a) Konqueror/5
b) dolphin/
which both are missing.

I conclude from the findings that:

I. All Debian changes [1][2] not yet there should also get upstream [in docs/conf/extra/httpd-dav.conf.in] (that way we also ensure to get their opinion in about the change in general)

II. The suggestions here seem right, that should go upstream to the same file as well

III. Once discussed accepted there we can be sure this does not back-fire, bring it up with Debian [for docs/conf/extra/httpd-dav.conf.in but there also debian/config-dir/mods-available/setenvif.conf]

IV. At the same time you can start to bring it into mantic [for docs/conf/extra/httpd-dav.conf.in but there also debian/config-dir/mods-available/setenvif.conf] and from there SRU

[Michał Małoszewski (michal-maloszewski99)]

Hi @Adam,

I tried to figure out how to create a Test Plan for it. And I think I did, but at the end, I had a problem adding a network folder in the Dolphin GUI.

What I did:

1. I started with focal VM, and I created it.
2. I've installed apache2 and the required modules as follows:
- a2enmod dav dav_fs
3. I've created a conf file under
/etc/apache2/sites-available/

and I have added it inside:

<VirtualHost *:80>
    ServerName localhost
    DocumentRoot /var/www/webdav

    Alias /webdav /var/www/webdav
    <Directory /var/www/webdav>
        DAV On
        AllowOverride None
        Require all granted
    </Directory>
</VirtualHost>

4. Then I enabled the new configuration and restarted apache2.

I have created a WebDAV directory and changed ownership:

sudo mkdir -p /var/www/webdav
sudo chown www-data:www-data /var/www/webdav

5. And then I installed Dolphin and wanted to access WebDAV with it, but I was denied access by Dolphin.

I think it might be another bug found along the way, or it might be a problem I only encountered.

Could you please help me a bit and maybe provide me with your steps to reproduce the issue?
I would be really grateful :)

[Adam Vodopjan (grozzly)]

I've just replicated your steps with a vm booted into ubuntu-20.04.6-desktop-amd64.iso and there are no problems with webdav for me aside for the bug reported:

(I ssh into the vm so when I say "copy-paste" it is literally that)

### install the stuff
- enable the universe repo in /etc/apt/sources.list
- sudo apt update
- sudo apt install apache2 dolphin
### configure apache
- sudo a2enmod dav dav_fs
- copy-paste your apache vhost config into /etc/apache2/sites-available/test.conf
- sudo a2ensite test.conf
- sudo systemctl restart apache2
### webdav dir
- sudo mkdir -p /var/www/webdav
- sudo chown www-data: /var/www/webdav

Now in dolphin, press C-l and enter path "webdav://localhost". There I can create files and dirs, delete files, but not delete dirs.

--

Try enabling the logs. Put these lines (as per /etc/apache2/sites-enabled/000-default.conf) into your test.conf:

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

and restart apache. And keep looking under /var/log/apache2/

[Michał Małoszewski (michal-maloszewski99)]

Thanks Adam!

I will redo my steps again tomorrow, and I hope it will work or at least the logs will be helpful.

FYI, if I still struggle with that test plan, can I ask you to test the PPA for me?
I would simply provide you with the fix in the PPA (link), and you would simply have to try to reproduce the issue.

[Adam Vodopjan (grozzly)]

I'll try to help with testing

[Michał Małoszewski (michal-maloszewski99)]

Hi Adam,

Finally, I was able to get rid of my "dolphin problem", but honestly, I went through Mantic, Lunar, Jammy and Focal and on none of them could I reproduce the issue.
I could create files and directories, delete files, _and_ delete directories.
I tried to determine if that applies exclusively to empty directories or directories with content inside, but I couldn't reproduce the issue either way.

Moreover out of curiosity, I did the same steps on the workstation I am working on daily (not only VMs), where the focal Ubuntu server is installed and the user is different than root, and I also couldn't reproduce that issue.

[Michał Małoszewski (michal-maloszewski99)]

Hmmm, I am wondering what might be the reason for that. Having in mind that I followed "your&mine" steps to reproduce it.

[Adam Vodopjan (grozzly)]

> I could create files and directories, delete files, _and_ delete directories.

When you say "delete dirs" have you actually checked if it was removed on disk? In dolphin it disappers from the view, but press F5 to refresh and it's still there.

[Adam Vodopjan (grozzly)]

You can see the problem even without actual dolphin, curl is enough. In focal with apache set up as above:

$> cd /var/www/webdav
$> mkdir a
$> chown www-data: a
$> curl -I -X DELETE http://localhost/a
HTTP/1.1 301 Moved Permanently
Date: Wed, 09 Aug 2023 16:05:00 GMT
Server: Apache/2.4.41 (Ubuntu)
Location: http://localhost/a/
Content-Length: 302
Content-Type: text/html; charset=iso-8859-1
$> curl -I -X DELETE -A 'prefix Konqueror/5' http://localhost/a
HTTP/1.1 301 Moved Permanently
Date: Wed, 09 Aug 2023 16:06:04 GMT
Server: Apache/2.4.41 (Ubuntu)
Location: http://localhost/a/
Content-Length: 302
Content-Type: text/html; charset=iso-8859-1
$> curl -I -X DELETE -A 'prefix Konqueror/4' http://localhost/a
HTTP/1.1 204 No Content
Date: Wed, 09 Aug 2023 16:09:28 GMT
Server: Apache/2.4.41 (Ubuntu)

See? It rejects (with redirect) curl's own user agent as well as Konqueror/5, which is dolphin in focal. But Konqueror/4 is OK since it is mentioned in `BrowserMatch " Konqueror/4" redirect-carefully` in /etc/apache2/mods-available/setenvif.conf

[Michał Małoszewski (michal-maloszewski99)]

Sure, that's true. First I wanted to reproduce it in the simplest way as the bug did not mention explicitly how the directory behaves after deletion, but after I wrote comment #13, I realised that it was not removed from the disk by doing: ls -li /path. Later, I saw your comment, and then I was sure it was a good way of thinking.

I tested it through releases, and Mantic, Lunar, Jammy and Focal are affected by that issue.

My next steps are:
1. Prepare patches for upstream as per comment#7 and test patches using the test case that I created. Then submit and discuss upstream.
2. Then I will take care of Debian and Ubuntu.

P.S. Btw, thank you Adam for being a really helpful and responsive bug reporter. I appreciate it.

[Michał Małoszewski (michal-maloszewski99)]

Created attachment 38897
Proposed patch

Operating system: Linux Ubuntu
Architecture: x86_64
kernel version: 6.3.0-7-generic

Dolphin in Ubuntu distros cannot delete webdav directories running on apache2.

Entries like:

BrowserMatch " Konqueror/5" redirect-carefully
and
BrowserMatch " dolphin/" redirect-carefully

within the docs/conf/extra/httpd-dav.conf.in are necessary to make it work properly.

Moreover, I've added some small changes that are present in Debian - (escape literal . in regexes and extend the gnome-vfs DAV workaround to gvfs) - that I could not find in the upstream source.

In the attachment, there is proposed patch.

I would like to get your opinion about the change in general.

[Michał Małoszewski (michal-maloszewski99)]

No answer from upstream. MP ready, will be uploaded early in 24.04

[Bryce Harrington (bryce)]

I don't doubt that Dolphin has identified itself as "dolphin" as well as "Konqueror/5" but other than this bug report I'm having difficulty finding confirmation of this via an official source. Pointers would be appreciated.

[Adam Vodopjan (grozzly)]

In jammy, source package "kio", kio-5.92.0/src/core/kprotocolmanager.cpp:793

    d->useragent = QLatin1String("Mozilla/5.0 (%1) ").arg(supp)
        + QLatin1String("KIO/%1.%2 ").arg(QString::number(KIO_VERSION_MAJOR), QString::number(KIO_VERSION_MINOR))
        + QLatin1String("%1/%2").arg(appName, appVersion);

In apache log I see "Mozilla/5.0 (X11; Linux x86_64) KIO/5.92 dolphin/21.12.3"

@bryce

In the rewritten first message you say "On the client-side, change the user agent in Dophin Settings > Customize > User Agent to Custom and then specify a supported user agent such as "Konqueror/4"

I'm not sure where it comes from. I dont see any way to customize dolphin's user agent in its interface in focal, jammy and mantic. There is no "customize" under settings but only "configure dolphin" and nothing related to user agent futher there. Mby those are some expert level settings I have to unhide first?

I mean here is what I see after selecting "settings > configure dolphin": https://docs.kde.org/stable5/en/dolphin/dolphin/configuring-dolphin.html

The only way I've found to change user agent was in focal: open "system settings > network > settings > browser identification", but it only works for selected sites: there is no way to globally override the default "Konqueror/5" piece. Besides, all options there are predefined, there is no way to enter a custom value and "Konqueror/4" is evidently not listed there.

In system setting for jammy and mantic there is no "browser identification" at all.
