Towards 3.2.0
by Rodrigo Arias Dec. 19, 2024

Dec. 19, 2024

Hi, I'm planning to close the feature window shortly, so I will need to think what else to include for 3.2.0 before it is closed. One of the features I would like to include is the ability to open a link with an external handler. We have a proof of concept that uses the rule file, but I think it is too complex for now: https://github.com/dillo-browser/dillo/pull/199 I'm thinking it may be better to add an easier variant first, that we can extend later. I'm considering adding these to dillorc: actions="default Open with external tool" actions="firefox Open with Firefox" actions="mpv Open with MPV" actions="mpv-audio Open with MPV (audio)" handler="/bin/the-handler" Where you can define multiple "actions" but only one "handler". The actions have a label at the beginning (first word) and a human readable text that will be presented in the menu. Then, your handler will be invoked using the label as: /bin/the-handler <URL> <action-label> And you do whatever you find convenient in your handler, so you have more context to decide the proper action based on the label. I think this would cover most of the use cases of opening URLs with other programs without being too convoluted. Best, Rodrigo.

[PATCH] make downloads.dpi use http_user_agent from dillorc

XSLT
by Schimon Jehudah Nov. 14, 2024

Nov. 14, 2024

Good day, everyone! I would want to know of an example or an elaboration as of how would it be possible to wriite a plugin which would parse XSLT. I want to know how to trigger Dillo to engage such type of a plugin. P.S. Did anyone examine my XMPP plugin for Dillo, yet? Kind regards, Schimon

XMPP PubSub Plugin
by Schimon Jehudah Nov. 9, 2024

Nov. 9, 2024

Good day, to one and all! My name is Schimon, I am a pianist, attorney at law, and I also work on software that mainly involve the technologies of Syndication and XMPP. My current intention, is to design an XMPP client, based on Slixmpp, to allow Dillo to interact with Atom Over XMPP (XEP-0277 and XEP-0472). Atom Over XMPP specifies storage of textual content (be it text or HTML) on XMPP PubSub nodes. It is useful for publishing (see Libervia, Movim, Rivista XJP), annotating resources (see Blasta) and for any sort of mean which may require textual content. References: https://blasta.woodpeckersnest.eu/help/about/xmpp/atomsub https://blasta.woodpeckersnest.eu/help/about/xmpp/pubsub Projects: https://schapps.woodpeckersnest.eu/blasta/ https://schapps.woodpeckersnest.eu/rivista/ I intend to utilize the Python computer language for this task. Any help, encouragement, and especially accompanying (not in the musical sense) my efforts be welcome. This is my first time which I intend to collaborate with Dillo developers, and I am excited by this opportunity. Kind regards, Schimon

[PATCH] Hide tab close button
by a1ex＠dismail.de Oct. 28, 2024

Oct. 28, 2024

Hi list, In an attempt to keep the UI as configurable as possible for accessibility and themeing purposes, here is an example patch to hide the close tab button. Since we can already close the tab with the right or middle mouse button click, the button might be useless for some users, and may also be taking up valuable horizontal real-estate in the tab bar. Maybe it seems silly, but when using Dillo on a constrained portrait display, this can be useful. It can probably be made into a dillorc option if there is any interest. --- a/src/uicmd.cc Mon Oct 28 19:01:28 2024 +++ b/src/uicmd.cc Mon Oct 28 19:01:57 2024 @@ -142,7 +142,7 @@ class CustTabs : public Fl_Group { (public) Fl_Group(0,0,ww,th,lbl) { Pack = NULL; focus_counter = 0; - tab_w = 50, tab_h = th, ctab_h = 1, btn_w = 20, ctl_w = 1*btn_w+2; + tab_w = 50, tab_h = th, ctab_h = 1, btn_w = 20; resize(0,0,ww,ctab_h); /* tab buttons go inside a pack within a scroll */ Scroll = new Fl_Scroll(0,0,ww-ctl_w,ctab_h); I've also done some preliminary work to theme the tab bar, scroll bar, url bar, icons, and ui highlights. Dillo isn't really designed for that, so to create a proper user configurable theme-engine will probably be quite a lot of work, and not something that I can handle alone. Regards, Alex

[WIP PATCH] Use SIGUSR1 to reload the page

Hi Rodrigo, I find your recent idea[0] to refresh the page on local file changes interesting, and it could be a quite useful feature.

Rendering issue with view source and large embedded images
by a1ex＠dismail.de Oct. 19, 2024

Oct. 19, 2024

Hi, There is a small rendering glitch when trying to view the source of a page which has larger embedded data uri images. See attached screenshot. This is an example of a page which uses large embedded jpegs: https://www.da.vidbuchanan.co.uk/blog/dram-emfi.html When you view the source in Dillo, the issue should be evident. Since the encoded image is just one super-long line in the html, the vsource dpi probably isn't designed to handle that. I don't think its typical that a site will embed large images into the page like this, but maybe its still worth considering. Regards, Alex

Navigation by pages
by a1ex＠dismail.de Oct. 18, 2024

Oct. 18, 2024

Hi Rodrigo, I saw your recent issue on GH: https://github.com/dillo-browser/dillo/issues/268 This is something I have thought about for quite a while. Basically, scrolling sucks, and it would be nice to be able to move up and down the page more cleanly. Obviously we can use PgUP/PgDN keys and spacebar, but I always wanted a way to do this with mouse-only. In the past I had scripted a small window which sits on-top of Dillo in the corner, which had 2 buttons: up and down. This works, but is a bit clunky. So, while I don't have a quick solution to the layout / pagination issues you mentioned, I created a simple toolbar icon which allows page navigation with the mouse. I think it really makes it easier when reading a long page. Patch and screenshot attached. Regards, Alex

scroll_step description
by Kevin Koster Oct. 17, 2024

Oct. 17, 2024

There's a new "scroll_step" option in the example configuration file for 3.1.0-rc1. The comment "Mouse wheel scroll step in pixels" suggests that this only affects the mouse wheel, but it also changes the distance the page moves when the arrow keys are pressed and the overlap of previous page content that's left when you press Page Up/Down. I think that's a little confusing, especially as the value has changed since the default behaviour in 3.0.5 (the old value seems to have been about 25).

'load_images' pref ineffective on embedded images
by a1ex＠dismail.de Oct. 1, 2024

Oct. 1, 2024

Hi, The pref 'load_images=NO' only disables loading images from a remote img src, and not from an embedded[1] data:image src. If this behavior is intentional, would it be reasonable to implement an option to disable all images? It might be the case that the user does not want to see any images, no matter the img src.

Feature idea: save tabs list
by a1ex＠dismail.de Sept. 15, 2024

Sept. 15, 2024

Hi, It would be nice to have the ability to save a list of open tabs. Often I find myself shutting down my workstation and still have many tabs open in Dillo. Its a pain to go through them all at that moment to decide whats worth saving or bookmarking. An option to save all open tab urls to a file would be great. It would be even nicer if we could later open all those urls in new tabs when starting Dillo :) On first glance it doesn't seem very easy to implement, but also maybe not super complicated either. I don't have any patches yet, just wanted to put the idea out and see what you think about it. Regards, Alex

Issues with HTTP multipart/form-data file upload
by Xavier Del Campo Romero Sept. 1, 2024

Sept. 1, 2024

Hello Dillo dev community, I am testing support among web browsers for slcl [1], a JS-less minimalist web storage solution. slcl relies on "multipart/form-data"-encoded HTTP requests to upload files to a server. Whereas Dillo helped me to uncover a few wrong assumptions on my code, I have realised a few issues on Dillo itself related to filue uploads that should be considered. Issue #1: While Dillo is fine uploading small files (up to a few MiB), things go wrong with larger files, so much that memory usage increases up to multiple GiB and can even lock the system up. This is because Dillo is designed to send requests always from memory, which means file contents must be dumped into memory first, and this might be unfeasible for large files. Suggestion: Instead, Dillo should ideally send file contents on-the-fly, so that memory usage is kept to a minimum regardless the file size. Issue #2: Even if Dillo generates a 70-byte, random boundary string (yet mostly filled with '-', similarly to Firefox [2]), it ensures it is not found anywhere inside the file contents. Again, this can be a serious bottleneck in the case of large files, as it requires to scan the whole file for a match. Suggestion: Define *all* of the 70 bytes in the boundary string as random, and assume they would never be found inside a file. The chance of accidental collision is so low that it is not worth the effort into checking them. Suggested patches: - 0001-dialog.cc-Generate-more-random-boundaries.patch) Issue #3: Dillo only supports uploading 1 file at a time. This is mostly because it relies (probably temporarily?) on the a_Dialog_save_file function [3]. However, this is not a limitation on the HTTP protocol, and other implementation such as Firefox or Chromium-based browsers support this. Suggested patches: - 0002-dialog-Add-a_Dialog_select_files.patch - 0003-WIP-multi-file-uploads.patch Conclusions: Dillo seems designed to always send requests from memory, so it is not straightforward to break this assumption in order to support large file uploads. 0003-WIP-multi-file-uploads.patch is an incomplete first step into fixing this, but it surely needs deeper design changes. I did not put more effort into these patches for the time being because, after seeing the potential complexity behind this task, I thought it was a better idea to ask the community for feedback and guidelines. Thank you very much for reading. Best regards, Xavier Del Campo Romero [1]: https://gitea.privatedns.org/xavi/slcl [2]: https://github.com/dillo-browser/dillo/blob/8a360e32ac3136494a494379a6dbbac… [3]: https://github.com/dillo-browser/dillo/blob/8a360e32ac3136494a494379a6dbbac…

TLS connect error: "an EOF was observed that violates the protocol"

Hi, Here are 2 separate issues: 1) socks5 proxy on 127.0.0.1:8080 not working. This is a proxy over ssh, for example: ssh -N -D 8080 user(a)example.com in dillorc: http_proxy="http://localhost:8080/" console output when trying to connect to a site: Connecting to 127.0.0.1:8080 CONNECT through proxy failed. Full reply not received: (nothing) ** WARNING **: CCC: call on already finished chain. Flags=CCC_Ended This setup works fine under Firefox. I tried doing a tcpdump while attempting the connection, and there is no activity.

[PATCH] dark mode for tooltips
by a1ex＠dismail.de Aug. 25, 2024

Hi, As part of an overall dark mode for Dillo, we could also consider the tooltips. Here is an example which I think looks reasonable: --- a/src/tipwin.cc Sun Aug 11 22:21:59 2024 +++ b/src/tipwin.cc Sat Aug 24 22:17:21 2024 @@ -40,7 +40,7 @@ static void recent_timeout(void*); */ TipWin::TipWin() : Fl_Menu_Window(1, 1) // will autosize { - bgcolor = fl_color_cube(FL_NUM_RED - 1, FL_NUM_GREEN - 1, FL_NUM_BLUE - 2); + bgcolor = FL_WHITE; recent = 0; tip[0] = '\0'; cur_widget = NULL; @@ -50,8 +50,8 @@ TipWin::TipWin() : Fl_Menu_Window(1, 1) // will au void TipWin::draw() { - draw_box(FL_BORDER_BOX, 0, 0, w(), h(), bgcolor); - fl_color(FL_BLACK); + draw_box(FL_BORDER_FRAME, 0, 0, w(), h(), bgcolor); + fl_color(FL_WHITE); fl_font(labelfont(), labelsize()); fl_draw(tip, 3, 3, w() - 6, h() - 6, //Fl_Align(FL_ALIGN_LEFT | FL_ALIGN_WRAP)); Note that 'ui_main_bg_color' needs to be set to the desired dark color first.

[PATCH v4] unveil patch
by a1ex＠dismail.de Aug. 22, 2024

Aug. 22, 2024

Hi, Here is an updated version of the unveil patch. I think almost everything on the to-do list was completed, except searching for a custom wget location. I don't see an especially easy way of doing that, and it seems an unlikely edge-case for someone to remove wget from the system default location. - Permissions have been tightened in dpis - Checking for AUTHORITY env, fallback to ~/.Xauthority - Prefs parser is aware of 'enable_unveil' - Fix some non-strict code warnings - dillorc 'enable_unveil' default setting - Formatting, whitespace fixes - ... I have done a fair amount of testing and it works for me. Unless there is any further feedback or interest, I will leave it as-is for now.

by Batavo Silva Aug. 20, 2024

Aug. 20, 2024

Hi Dillo devs! Here is just a small bug fix for the Cipboard copy function. The 3rd argument passed for the Fl::copy() function should be 1 (not 0) for it to copy the input text to the clipboard buffer. This issue is found at line 702 of file dillo/dw/fltkplatform.cc: [code] void FltkPlatform::copySelection(const char *text) { Fl::copy(text, strlen(text), 0); // wrong } [/code] Change it to: [code] void FltkPlatform::copySelection(const char *text) { Fl::copy(text, strlen(text), 1); } [/code] Ref: FLTK Documentation: https://www.fltk.org/doc-1.3/group__fl__clipboard.html#ga221bc2fa9bd737a825…

portability: gmake vs make
by a1ex＠dismail.de Aug. 11, 2024

Aug. 11, 2024

Hi Rodrigo, Looking at your recent commit: >Make Dillo strictly C99, C++11 and POSIX-2001 compliant, without >depending on GNU extensions. Right now the OpenBSD port of Dillo is dependent on gmake (GNU make) to build the package. Out of curiosity, I tried to use the native 'make' command: $ make [...] Making all in doc Using $< in a non-suffix rule context is a GNUmake idiom (Makefile:556) *** Error 1 in . (Makefile:583 'all-recursive') *** Error 2 in . (Makefile:380 'all') Everything else builds fine, except this error in doc. Here is the offending line: $ diff -up a/doc/Makefile.am b/doc/Makefile.am --- a/doc/Makefile.am Sun Aug 11 00:01:58 2024 +++ b/doc/Makefile.am Sun Aug 11 00:01:51 2024 @@ -11,6 +11,6 @@ dillo.1: $(srcdir)/dillo.1.in Makefile # Use .in.html instead of .html.in so it is recognized as HTML. user_help.html: $(srcdir)/user_help.in.html Makefile - sed 's/__VERSION__/${VERSION}/g' $< > $@ DISTCLEANFILES = dillo.1 user_help.html With that removed, there are no errors.

[PATCH v3] unveil patch
by a1ex＠dismail.de Aug. 8, 2024

Aug. 8, 2024

Hi, Here is a new version of the unveil patch. Some notable changes: - Dillo will exit if 'save_dir' is set to $HOME (only with unveil) - dUnveil() function moved to dlib - New 'enable_unveil' pref for dillorc - New dGetsavedir() function to parse 'save_dir' - New dGetenableunveil() function to parse 'enable_unveil' enable_unveil is not used by the prefs parser, but rather dGetenableunveil(). I still need to fix it so that we don't get this warning on the console: prefs: {enable_unveil} is not a recognized token. To-Do: - Localize wget and $AUTHORITY - ... As always, feedback is welcome.

[PATCH] Toolbar zoom control button
by a1ex＠dismail.de Aug. 8, 2024

Aug. 8, 2024

Hi list, Here is an improved version of my previous patch. The icon is fixed, it's basic but does the job. If someone wants to make a prettier one, I'm open to it. Other improvements as discussed with Rodrigo: - Middle click resets zoom level - There is now a 'show_zoom' preference in dillorc (enabled by default) - The save button has been disabled by default - The zoom button has been moved to the right of the refresh button Please let me know if you find any issues, and hope you enjoy it :) Regards, Alex diff -upr a/dillorc b/dillorc --- a/dillorc Sun Jul 14 18:25:44 2024 +++ b/dillorc Sun Jul 14 18:25:59 2024 @@ -366,7 +366,8 @@ ui_tab_bg_color=#b7beb7 #show_forw=YES #show_home=YES #show_reload=YES -#show_save=YES +#show_zoom=YES +#show_save=NO #show_stop=YES #show_bookmarks=YES #show_tools=YES diff -upr a/src/pixmaps.h b/src/pixmaps.h --- a/src/pixmaps.h Sun Jul 14 18:25:44 2024 +++ b/src/pixmaps.h Sun Jul 14 18:25:59 2024 @@ -809,6 +809,35 @@ static const char *const tools_xpm[] = { " -&X6&=# ", " "};

[PATCH v2] Unveil patch
by a1ex＠dismail.de Aug. 5, 2024

Aug. 5, 2024

Hi, Here is version 2 of my unveil patch. Many thanks to Rodrigo for his kind assistance! Improvements: - Unveil is disabled by default. It can be enabled using: configure --enable-unveil - There is now a dUnveil() wrapper which simplifies the code and error handling - Locale check and custom cursor icons unveil fix To-Do: - Add prefs parsing to plugins to get 'save_dir' (may need help here) - Add a dillorc pref to enable/disable unveil (same issue as above) - Localize wget and $AUTHORITY - A few other items from my previous to-do list Regards, Alex diff -upr a/configure.ac b/configure.ac --- a/configure.ac Sat Jul 27 12:54:47 2024 +++ b/configure.ac Thu Aug 1 16:40:16 2024 @@ -36,6 +36,11 @@ AC_ARG_ENABLE([insure], [enable_insure=$enableval], [enable_insure=no]) +AC_ARG_ENABLE([unveil], + [AS_HELP_STRING([--enable-unveil], [Build with support for unveil])], + [enable_unveil=$enableval], + [enable_unveil=no]) + AC_ARG_ENABLE([ipv6], [AS_HELP_STRING([--enable-ipv6], [Build with support for IPv6])], [enable_ipv6=$enableval], @@ -619,6 +624,9 @@ if test "x$enable_insure" = "xyes" ;

Blurry font
by Miles Wirht Aug. 5, 2024

Aug. 5, 2024

Hello! I've been using the dillo browser to open emails, and I've noticed that oftentimes fonts will render blurry, or if they don't, they'll become blurry upon a mouse click or any other interaction. Is thare an antialising option I'm missing, or is this a deeper issue? Thank you for your support.

Debian package endorsement request
by Rodrigo Arias Aug. 5, 2024

Aug. 5, 2024

Hi all, I've been trying to update the Dillo Debian package from 3.0.5 to the 3.1.1 version of our repository: https://github.com/dillo-browser/dillo As commented on Fediverse by the maintainer of the Debian package, Axel Beckert (in CC), it would help having an endorsement from previous developers, so we can avoid a xz situation due to the change in upstream: https://fosstodon.org/@xtaran@chaos.social/112909239587911469 Here are all the changes among 3.0.5 and 3.1.1, which contain a lot of commits from Sebastian: https://github.com/dillo-browser/dillo/compare/3.0.5...v3.1.1 And here since the last commit from the original mercurial repo: https://github.com/dillo-browser/dillo/compare/c9b817f5bb8ef2060aa36ebb5b08… I'm adding the dillo-dev mailing list, so we can have a public record, in case we have a similar trust problem in the future. Thanks in advance, Rodrigo.

dpid doesn't work if configured with "--program-suffix=-new"
by Detlef Vollmann July 31, 2024

July 31, 2024

Hello, for the time being I'd like to install the current dillo version, next to the old existing one. So I configured with "--program-suffix=-new". Browsing works fine, but plugins (including bm or file) can't be started, as the binary is called "dpid-new" but dillo tries to start "dpid". It probaly wouldn't work anyway as $HOME/.dillo is hardcoded and there's no way to give a separate configuration directory (and sharing .dillo between different version is probably not a good idea). But it would be cleaner not to support "--program-suffix". Detlef

This brings up a completely separate question: why is wget hardcoded and not changeable as the downloader, and also has a hardcoded useragent which can't be changed by the user. To me, that's not ideal, and maybe you have some thoughts on it. > The .Xauthority file should be read from $AUTHORITY and then from > there if not set. I will try :) > Not sure if we want to constraint file:// like this. What if we are > using Dillo to read local HTML files in ~/? Would you prefer to just not do any unveil in file.c then? It's probably not a huge risk. > Plugins can also be found on the dpi_dir directory defined by the > user in the .dillo/dpidrc, so we would need to parse it first. I will look at it, but this could be more difficult for me. > I would also protect dpidrc from writing as well as dillorc. Agreed. No problem. Regards, Alex

I don't want to overwhelm the list and devs with my beginner programming mistakes, it feels like I'm placing an unfair burden on you. Regards, Alex

Updated unveil patch
by a1ex＠dismail.de July 29, 2024

July 29, 2024

Hi, Here is a new patch. I have done quite a bit more work on this and think it may be close to completion. The '~/Downloads' directory has been unveiled to match the behavior of Firefox and Chromium on OpenBSD, but Dillo's default of '/tmp' continues to work as well. I have also made sure everything works fine when there is no ~/.dillo directory, Dillo can create it, and also can access the system defaults in '/usr/local/etc/dillo'. dpid is also now unveiled, as well as all of the stock plugins except hello.dpi, I didn't see any point to that. Here are some other tests which I have run: - Regular browsing works fine - Connect to an FTP site and download a file, also view a text file and view an image - Open a text and image file from /tmp and ~/Downloads - Add/remove bookmarks - Download a file to /tmp and ~/Downloads - Save a page to /tmp and ~/Downloads - View source still works - Fonts and cursor icons are working correctly - data: uri works correctly with text and images So far everything seems to be fine. I will keep testing, but would really appreciate some help with reviewing this, there could be some edge-cases which I missed.

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; }

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

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
