Does :hover work in 3.1.1?
by Steinar Bang July 27, 2024

July 27, 2024

Does :hover work in 3.1.1? I am trying to write a JavaScript-less dropdown to switch locale as e.g. outlined here: https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_responsive_nav… Short story: the dropdown is an ul with "display: none" and hovering over a parent element (that is displayed) is supposed to switch to "display: block". But nothing happens when I hover over the parent. Google found me this, dated August 19 2022, listing pseudo-classes as Pending, but August 19 2022 is almost two years ago...? https://dillo.org/css.html (looks like that "Pending" may be from January 1 2015...?) If :hover doesn't work I will have to do it a different way: maybe with a separate settings page containing a form...? Here is the HTML of the dropdown: <li> <div class="locale-dropdown"> <a href="">Language</a> <ul class="locale-dropdown-content"> <li><a href="">English</a></li> <li><a href="">norsk bokmål</a></li> </ul> </div> </li> (the dropdown is nested in a <li> that is part of the <ul> that forms the <nav>) The CSS looks like this: .locale-dropdown-content { display: none; position: absolute; background-color: #f9f9f9; min-width: 160px; box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2); z-index: 1; } .locale-dropdown:hover .locale-dropdown-content { display: block; }

Is CSS inline-block on <ul> supposed to work
by Steinar Bang July 26, 2024

July 26, 2024

dillo 3.1.1, debian 12.6 "bookworm", amd64 I am trying to create a <nav> "powered by" an <ul>: <nav class="image-navbar"> <ul> <li><a href="blah">item 1</a></li> <li><a href="bluh">item 2</a></li> </ul> </nav> But I am unable to make the <ul> render horizontally. Is "display: inline-bloc" supposed to work on dillo 3.1.1? Here's the CSS I've tried: nav.image-navbar { background-color: lightgray; padding-bottom: 10px; } nav.image-navbar ul { list-style-type: none; display: inline-block; vertical-align: top; margin: 0; padding: 0; } nav.image-navbar ul li { float: left; } Thanks! - Steinar

Unveil Dillo (new patch)
by a1ex＠dismail.de July 25, 2024

July 25, 2024

Hi list, Here is an updated patch which now just does unveil (no pledge). I have tightened up the permissions so that Dillo only has the minimum of filesystem access, just enough so that everything still (hopefully) works. Testers and comments welcome. There probably aren't many OpenBSD users on this list, so I will eventually submit this to the OpenBSD ports list for further review. --- a/src/dillo.cc Thu Jul 25 21:21:14 2024 +++ b/src/dillo.cc Thu Jul 25 21:28:54 2024 @@ -23,6 +23,7 @@ #include <stdio.h> #include <unistd.h> +#include <err.h> #include <stdlib.h> #include <time.h> #include <sys/types.h> @@ -396,6 +397,41 @@ int main(int argc, char **argv) srand((uint_t)(time(0) ^ getpid())); + // unveil() + if (unveil("/usr/local/share/fonts", "r") == -1) { + err(1, "unveil failed"); + } + if (unveil("/tmp", "rw") == -1) { + err(1, "unveil failed"); + } + if (unveil("/usr/local/bin/dpid", "x") == -1) { + err(1, "unveil failed"); + } + if (unveil("/etc/fonts", "r") == -1) { + err(1, "unveil failed"); + } + if (unveil("/etc/resolv.conf", "r") == -1) { + err(1, "unveil failed"); + } + if (unveil("/etc/ssl/cert.pem", "r") == -1) { + err(1, "unveil failed"); + } + char *dl_loc = dStrconcat(dGethomedir(), "/Downloads", NULL); + if (unveil(dl_loc, "rw") == -1) { + err(1, "unveil failed"); + } + dFree(dl_loc); + char *dil_loc = dStrconcat(dGethomedir(), "/.dillo", NULL); + if (unveil(dil_loc, "rwc") == -1) { + err(1, "unveil failed"); + } + dFree(dil_loc); + char *xauth_loc = dStrconcat(dGethomedir(), "/.Xauthority", NULL); + if (unveil(xauth_loc, "r") == -1) { + err(1, "unveil failed"); + } + dFree(xauth_loc); + // Some OSes exit dillo without this (not GNU/Linux). signal(SIGPIPE, SIG_IGN); // Establish our custom SIGCHLD handler The only small issue I see so far is that the ~/Downloads directory is now hardcoded, and so the 'save_dir' preference in dillorc will need to match. Also note that in order to be able to use Rodrigo's multiple-actions patch with this, or my external link handler patch, you will also need to add: if (unveil("/bin/sh", "x") == -1) { err(1, "unveil failed"); } But that's not really advisable if you are looking for maximum security. EDIT: I just realized we may need to unveil dpid as well. Since it's a separate process, I don't think it inherits the unveil from dillo.cc. For example, when I use the 'Open file...' dialog, I am unable to see the restricted directories. However, when I load 'file:/home/user' in the browser, the contents still show up. Back to the drawing board! I will try to look at that in the next few days if possible. Regards, Alex

Hardening Dillo with unveil and pledge
by a1ex＠dismail.de July 25, 2024

July 25, 2024

Hi list, I have been experimenting with unveil[1] and pledge[2] on Dillo to reduce possible attack surface. Right now these system calls are exclusive to OpenBSD, but there are projects[3] working to bring them to Linux and other systems. Basically, unveil restricts which areas of the filesystem a program can access, and pledge restricts which system calls the program is allowed to make. [1] https://man.openbsd.org/unveil.2 [2] https://man.openbsd.org/pledge.2 [3] https://justine.lol/pledge/ Initial testing indicates that both of these features are working correctly with Dillo. I am including a patch which provides some basic filesystem protection, and limits Dillo to the minimum amount of syscalls possible. If anyone has questions or comments, they are welcome.

[SCRIPT] Run Dillo with a random user agent
by a1ex＠dismail.de July 14, 2024

Hi list, Here is a simple script which runs Dillo with a random user agent on each run. I've been using it for a long time with no issues. It would be interesting to have similar functionality built-in to Dillo at some point, at least for me. $ cat rundillo.sh #!/bin/sh # runs dillo with a random user agent, from a list in agents.txt # the ua must be the last line of dillorc, this deletes it: echo -e '$d\nw\nq'| ed ~/.dillo/dillorc # put a random ua line from agents.txt into the last line of dillorc # each line in agents.txt must include http_user_agent='...' cat ~/.dillo/agents.txt | sort -R | head -1 >> ~/.dillo/dillorc # run dillo: dillo ------------------------------- Here is an example 'agents.txt': http_user_agent='Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:123.0) Gecko/20100101 Firefox/123.0' http_user_agent='Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:124.0) Gecko/20100101 Firefox/124.0' http_user_agent='Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:125.0) Gecko/20100101 Firefox/125.0' http_user_agent='Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:126.0) Gecko/20100101 Firefox/126.0' http_user_agent='Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:127.0) Gecko/20100101 Firefox/127.0' http_user_agent='Mozilla/5.0 (Macintosh; Intel Mac OS X 14.5; rv:123.0) Gecko/20100101 Firefox/123.0' http_user_agent='Mozilla/5.0 (Macintosh; Intel Mac OS X 14.5; rv:124.0) Gecko/20100101 Firefox/124.0' http_user_agent='Mozilla/5.0 (Macintosh; Intel Mac OS X 14.5; rv:125.0) Gecko/20100101 Firefox/125.0' http_user_agent='Mozilla/5.0 (Macintosh; Intel Mac OS X 14.5; rv:126.0) Gecko/20100101 Firefox/126.0' http_user_agent='Mozilla/5.0 (Macintosh; Intel Mac OS X 14.5; rv:127.0) Gecko/20100101 Firefox/127.0' ------------------------------ Just make sure there are no blank lines or comments in agents.txt Anyway, hopefully this will be useful to someone.

Option to define external link handler
by a1ex＠dismail.de July 13, 2024

July 13, 2024

Hi Rodrigo and list, Thanks for all the recent improvements! I have one more feature which I would like to propose, or hopefully at least get some guidance with. An option to open a link with an external program. This could be a custom downloader, or whatever else the user wants. Ideally it would be a setting in dillorc, something like: external_downloader="/usr/bin/some_command -x -y -z" And in the right-click Link menu there would be an option to open the link with the external program, something like "Open link with external app". I can envision various workflows, especially repetitive ones, in which this would be a real time-saver. There is nothing really wrong with the built-in downloader, but it's not always ideal. Obviously it's possible to copy the link and use it in whatever program, but that results in extra clicks / key-presses. Is there any interest in a feature like this? I've been looking at the source, but am not really seeing a way to easily replace the current download program (or even where it is defined). If anyone has hints on how to do this, I'd appreciate the help. Or, even better, someone more talented could step up and implement the feature :) Regards, Alex
