Russell Coker: SE Linux Policy for Dell Management

The recent issue of Windows security software killing computers has reminded me about the issue of management software for Dell systems. I wrote policy for the Dell management programs that extract information from iDRAC and store it in Linux. After the break I ve pasted in the policy. It probably needs some changes for recent software, it was last tested on a PowerEdge T320 and prior to that was used on a PowerEdge R710 both of which are old hardware and use different management software to the recent hardware. One would hope that the recent software would be much better but usually such hope is in vain. I deliberately haven t submitted this for inclusion in the reference policy because it s for proprietary software and also it permits many operations that we would prefer not to permit. The policy is after the break because it s larger than you want on a Planet feed. But first I ll give a few selected lines that are bad in a noteworthy way:
  1. sys_admin means the ability to break everything
  2. dac_override means break Unix permissions
  3. mknod means a daemon creates devices due to a lack of udev configuration
  4. sys_rawio means someone didn t feel like writing a device driver, maintaining a device driver for DKMS is hard and getting a driver accepted upstream requires writing quality code, in any case this is a bad sign.
  5. self:lockdown is being phased out, but used to mean bypassing some integrity protections, that would usually be related to sys_rawio or similar.
  6. dev_rx_raw_memory is bad, reading raw memory allows access to pretty much everything and execute of raw memory is something I can t imagine a good use for, the Reference Policy doesn t use this anywhere!
  7. dev_rw_generic_chr_files usually means a lack of udev configuration as udev should do that.
  8. storage_raw_write_fixed_disk shouldn t be needed for this sort of thing, it doesn t do anything that involves managing partitions.
Now without network access or other obvious ways of remote control this level of access while excessive isn t necessarily going to allow bad things to happen due to outside attack. But if there are bugs in the software there s nothing to stop it from giving the worst results.

Enrico Zini: meson, includedir, and current directory

Suppose you have a meson project like this: meson.build:
project('example', 'cpp', version: '1.0', license : ' ', default_options: ['warning_level=everything', 'cpp_std=c++17'])
subdir('example')
example/meson.build:
test_example = executable('example-test', ['main.cc'])
example/string.h:
/* This file intentionally left empty */
example/main.cc:
#include <cstring>
int main(int argc,const char* argv[])
 
    std::string foo("foo");
    return 0;
 
This builds fine with autotools and cmake, but not meson:

It turns out that meson adds the current directory to the include path by default:
Another thing to note is that include_directories adds both the source directory and corresponding build directory to include path, so you don't have to care.
It seems that I have to care after all. Thankfully there is an implicit_include_directories setting that can turn this off if needed. Its documentation is not as easy to find as I'd like (kudos to Kangie on IRC), and hopefully this blog post will make it easier for me to find it in the future.

Dirk Eddelbuettel: Rcpp 1.0.13 on CRAN: Some Updates

rcpp logo The Rcpp Core Team is once again pleased to announce a new release (now at 1.0.13) of the Rcpp package. It arrived on CRAN earlier today, and has since been uploaded to Debian. Windows and macOS builds should appear at CRAN in the next few days, as will builds in different Linux distribution and of course r2u should catch up tomorrow too. The release was uploaded last week, but not only does Rcpp always gets flagged because of the grandfathered .Call(symbol) but CRAN also found two packages regressing which then required them to take five days to get back to us. One issue was known; another did not reproduce under our tests against over 2800 reverse dependencies leading to the eventual release today. Yay. Checks are good and appreciated, and it does take time by humans to review them. This release continues with the six-months January-July cycle started with release 1.0.5 in July 2020. As a reminder, we do of course make interim snapshot dev or rc releases available via the Rcpp drat repo as well as the r-universe page and repo and strongly encourage their use and testing I run my systems with these versions which tend to work just as well, and are also fully tested against all reverse-dependencies. Rcpp has long established itself as the most popular way of enhancing R with C or C++ code. Right now, 2867 packages on CRAN depend on Rcpp for making analytical code go faster and further, along with 256 in BioConductor. On CRAN, 13.6% of all packages depend (directly) on Rcpp, and 59.9% of all compiled packages do. From the cloud mirror of CRAN (which is but a subset of all CRAN downloads), Rcpp has been downloaded 86.3 million times. The two published papers (also included in the package as preprint vignettes) have, respectively, 1848 (JSS, 2011) and 324 (TAS, 2018) citations, while the the book (Springer useR!, 2013) has another 641. This release is incremental as usual, generally preserving existing capabilities faithfully while smoothing our corners and / or extending slightly, sometimes in response to changing and tightened demands from CRAN or R standards. The move towards a more standardized approach for the C API of R leads to a few changes; Kevin did most of the PRs for this. Andrew Johnsom also provided a very nice PR to update internals taking advantage of variadic templates. The full list below details all changes, their respective PRs and, if applicable, issue tickets. Big thanks from all of us to all contributors!

Changes in Rcpp release version 1.0.13 (2024-07-11)
  • Changes in Rcpp API:
    • Set R_NO_REMAP if not already defined (Dirk in #1296)
    • Add variadic templates to be used instead of generated code (Andrew Johnson in #1303)
    • Count variables were switches to size_t to avoid warnings about conversion-narrowing (Dirk in #1307)
    • Rcpp now avoids the usage of the (non-API) DATAPTR function when accessing the contents of Rcpp Vector objects where possible. (Kevin in #1310)
    • Rcpp now emits an R warning on out-of-bounds Vector accesses. This may become an error in a future Rcpp release. (Kevin in #1310)
    • Switch VECTOR_PTR and STRING_PTR to new API-compliant RO variants (Kevin in #1317 fixing #1316)
  • Changes in Rcpp Deployment:
    • Small updates to the CI test containers have been made (#1304)

Thanks to my CRANberries, you can also look at a diff to the previous release Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page. Bugs reports are welcome at the GitHub issue tracker as well (where one can also search among open or closed issues). If you like this or other open-source work I do, you can sponsor me at GitHub.

This post by Dirk Eddelbuettel originated on his Thinking inside the box blog. Please report excessive re-aggregation in third-party for-profit settings.

Kalyani Kenekar: Securing Your Website: Installing and Configuring Nginx with SSL

Logo Nginx

The Initial Encounter: I recently started to work with Nginx to explore the requirements on how to configure a then so called server block. It s quite different than within Apache. But there are a tons of good websites out there which do explain the different steps and options quite well. I also realized quickly that I need to be able to configure my Nginx setups in a way so the content is delivered through https with some automatic redirection from http URLs.
  • Let s install Nginx

Installing Nginx
$ sudo apt update
$ sudo apt install nginx

Checking your Web Server
  • We can check now nginx service is active or inactive
Output
  nginx.service - A high performance web server and a reverse proxy server
     Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)
     Active: active (running) since Tue 2024-02-12 09:59:20 UTC; 3h ago
       Docs: man:nginx(8)
   Main PID: 2887 (nginx)
      Tasks: 2 (limit: 1132)
     Memory: 4.2M
        CPU: 81ms
     CGroup: /system.slice/nginx.service
              2887 nginx: master process /usr/sbin/nginx -g daemon on; master_process on;
              2890 nginx: worker process
  • Now we successfully installed nginx and it in running state.

How To Secure Nginx with Let s Encrypt on Debian 12
  • In this documentation, you will use Certbot to obtain a free SSL certificate for Nginx on Debian 12 and set up your certificate.

Step 1 Installing Certbot $ sudo apt install certbot python3-certbot-nginx
  • Certbot is now ready to use, but in order for it to automatically configure SSL for Nginx, we need to verify some of Nginx s configuration.

Step 2 Confirming Nginx s Configuration
  • Certbot needs to be able to find the correct server block in your Nginx configuration for it to be able to automatically configure SSL. Specifically, it does this by looking for a server_name directive that matches the domain you request a certificate for. To check, open the configuration file for your domain using nano or your favorite text editor.
$ sudo vi /etc/nginx/sites-available/example.com
 server  
    listen 80;
    root /var/www/html/;
    index index.html;
    server_name example.com
    location /  
        try_files $uri $uri/ =404;
     
    location /test.html  
        try_files $uri $uri/ =404;
        auth_basic "admin area";
        auth_basic_user_file /etc/nginx/.htpasswd;
     
 
  • Fillup above data your project wise and then save the file, quit your editor, and verify the syntax of your configuration edits.
$ sudo nginx -t

Step 3 Obtaining an SSL Certificate
  • Certbot provides a variety of ways to obtain SSL certificates through plugins. The Nginx plugin will take care of reconfiguring Nginx and reloading the config whenever necessary. To use this plugin, type the following command line.
$ sudo certbot --nginx -d example.com
  • The configuration will be updated, and Nginx will reload to pick up the new settings. certbot will wrap up with a message telling you the process was successful and where your certificates are stored.
Output
IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at:
   /etc/letsencrypt/live/example.com/fullchain.pem
   Your key file has been saved at:
   /etc/letsencrypt/live/example.com/privkey.pem
   Your cert will expire on 2024-05-12. To obtain a new or tweaked
   version of this certificate in the future, simply run certbot again
   with the "certonly" option. To non-interactively renew *all* of
   your certificates, run "certbot renew"
 - If you like Certbot, please consider supporting our work by:
   Donating to ISRG / Let's Encrypt:   https://letsencrypt.org/donate
   Donating to EFF:                    https://eff.org/donate-le
  • Your certificates are downloaded, installed, and loaded. Next check the syntax again of your configuration.
$ sudo nginx -t
  • If you get an error, reopen the server block file and check for any typos or missing characters. Once your configuration file s syntax is correct, reload Nginx to load the new configuration.
$ sudo systemctl reload nginx
  • Try reloading your website using https:// and notice your browser s security indicator. It should indicate that the site is properly secured, usually with a lock icon.
Now your website is secured by SSL usage.

Gunnar Wolf: Script for weather reporting in Waybar

While I was living in Argentina, we (my family) found ourselves checking for weather forecasts almost constantly weather there can be quite unexpected, much more so that here in Mexico. So it took me a bit of tinkering to come up with a couple of simple scripts to show the weather forecast as part of my Waybar setup. I haven t cared to share with anybody, as I believe them to be quite trivial and quite dirty. But today, V ctor was asking for some slightly-related things, so here I go. Please do remember I warned: Dirty. Forecast I am using OpenWeather s open API. I had to register to get an APPID, and it allows me for up to 1,000 API calls per day, more than plenty for my uses, even if I am logged in at my desktops at three different computers (not an uncommon situation). Having that, I set up a file named /etc/get_weather/, that currently reads:
# Home, Mexico City
LAT=19.3364
LONG=-99.1819
# # Home, Paran , Argentina
# LAT=-31.7208
# LONG=-60.5317
# # PKNU, Busan, South Korea
# LAT=35.1339
#LONG=129.1055
APPID=SomeLongRandomStringIAmNotSharing
Then, I have a simple script, /usr/local/bin/get_weather, that fetches the current weather and the forecast, and stores them as /run/weather.json and /run/forecast.json:
#!/usr/bin/bash
CONF_FILE=/etc/get_weather
if [ -e "$CONF_FILE" ]; then
    . "$CONF_FILE"
else
    echo "Configuration file $CONF_FILE not found"
    exit 1
fi
if [ -z "$LAT" -o -z "$LONG" -o -z "$APPID" ]; then
    echo "Configuration file must declare latitude (LAT), longitude (LONG) "
    echo "and app ID (APPID)."
    exit 1
fi
CURRENT=/run/weather.json
FORECAST=/run/forecast.json
wget -q "https://api.openweathermap.org/data/2.5/weather?lat=$ LAT &lon=$ LONG &units=metric&appid=$ APPID " -O "$ CURRENT "
wget -q "https://api.openweathermap.org/data/2.5/forecast?lat=$ LAT &lon=$ LONG &units=metric&appid=$ APPID " -O "$ FORECAST "
This script is called by the corresponding systemd service unit, found at /etc/systemd/system/get_weather.service:
[Unit]
Description=Get the current weather
[Service]
Type=oneshot
ExecStart=/usr/local/bin/get_weather
And it is run every 15 minutes via the following systemd timer unit, /etc/systemd/system/get_weather.timer:
[Unit]
Description=Get the current weather every 15 minutes
[Timer]
OnCalendar=*:00/15:00
Unit=get_weather.service
[Install]
WantedBy=multi-user.target
(yes, it runs even if I m not logged in, wasting some of my free API calls but within reason) Then, I declare a "custom/weather" module in the desired position of my ~/.config/waybar/waybar.config, and define it as:
"custom/weather":  
    "exec": "while true;do /home/gwolf/bin/parse_weather.rb;sleep 10; done",
"return-type": "json",
 ,
This script basically morphs a generic weather JSON description into another set of JSON bits that display my weather in the way I prefer to have it displayed as:
#!/usr/bin/ruby
require 'json'
Sources =  :weather => '/run/weather.json',
           :forecast => '/run/forecast.json'
           
Icons =  '01d' => ' ', # d   day
         '01n' => ' ', # n   night
         '02d' => ' ',
         '02n' => ' ',
         '03d' => ' ',
         '03n' => ' ',
         '04d'  => ' ',
         '04n' => ' ',
         '09d' => ' ',
         '10n' =>  '  ',
         '10d' => ' ',
         '13d' => ' ',
         '50d' => ' '
         
ret =  'text': nil, 'tooltip': nil, 'class': 'weather', 'percentage': 100 
# Current weather report: Main text of the module
begin
  weather = JSON.parse(open(Sources[:weather],'r').read)
  loc_name = weather['name']
  icon = Icons[weather['weather'][0]['icon']]   ' ' + f['weather'][0]['icon'] + f['weather'][0]['main']
  temp = weather['main']['temp']
  sens = weather['main']['feels_like']
  hum = weather['main']['humidity']

The end result? Nothing too stunning, but definitively something I find useful and even nicely laid out: Screenshot Do note that it seems OpenWeather will return the name of the closest available meteorology station with (most?) recent data for my home, I often get Ciudad Universitaria, but sometimes Coyoac n or even San ngel Inn.

Mike Gabriel: Weather Experts with Translation Skills Needed!

Lomiri Weather App goes Open Meteo In Ubuntu Touch / Lomiri, Maciej Sopy o has updated Lomiri's Weather App to operate against a different weather forecast provider (Open Meteo). Additionally, the new implementation is generic and pluggable, so other weather data providers can be added-in later. Big thanks to Maciej for working on this just in time (the previous implementation's API has recently been EOL'ed and is not available anymore to Ubuntu Touch / Lomiri users). Lomiri Weather App - new Meteorological Terms part of the App now While the old weather data provider implementation obtained all the meteorological information as already localized strings from the provider, the new implementation requires all sorts of weather conditions being translated within the Lomiri Weather App itself. The meteorological terms are probably not easy to translate for the usual software translator, so special help might be required here. Call for Translations: Lomiri Weather App So, if you feel entitled to help here, please join the Hosted Weblate service [1] and start working on Lomiri Weather App. Thanks a lot! light+love

Russell Coker: Samsung Galaxy Note 9 Review

After the VoLTE saga [1] and the problems with battery life on the PinePhonePro [2] (which lasted 4 hours while idle with the screen off in my last test a few weeks ago) I m running a Galaxy Note 9 [3] with the default Samsung OS as my daily driver. I don t think that many people will be rushing out to buy a 2018 phone regardless of my review. For someone who wants a phone of such age (which has decent hardware and a low price) then good options are the Pixel phones which are all supported by LineageOS. I recommend not buying this phone due to the fact that it doesn t have support for VoLTE with LineageOS (and presumably any other non-Samsung Android build) and doesn t have support from any other OS. The One Plus 6/6T has Mobian support [4] as well as LineageOS support and is worth considering. The Note 9 still has capable hardware by today s standards. A 6.4 display is about as big as most people want in their pocket and 2960 1440 resolution in that size (516dpi) is probably as high as most people can see without a magnifying glass. The model I m using has 8G of RAM which is as much as the laptop I was using at the start of this year. I don t think that many people will have things that they actually want to do on a phone which needs more hardware than this. The only hardware feature in new phones which beats this is the large folding screen in some recent phones, but $2500+ (the price of such phones in Australia) is too much IMHO and the second hand market for folding phones is poor due to the apparently high incidence of screens breaking. The Note 9 has the Dex environment for running as a laptop if you connect it to a USB-C dock. It can run nicely with a 4K monitor with USB keyboard and mouse. The UI is very similar to that of older versions of Windows. The Samsung version of Android seems mostly less useful than the stock Google version or the LineageOS version. The Samsung keyboard flags words such as gay as spelling errors and it can t be uninstalled even when you install a better keyboard app. There is a Bixby button on the side of the phone to launch the Bixby voice recognition app which can t be mapped to any useful purpose, The Google keyboard has a voice dictation option which I will try out some time but that s all I desire in terms of voice recognition. There are alerts about Samsung special deals and configuration options including something about signing in to some service and having it donate money to charity, I doubt that any users want such features. Apart from Dex the Samsung Android build is a good advert for LineageOS. The screen has curved sides for no good reason. This makes it more difficult to make a protective phone case as a case can t extend beyond the screen at the sides and therefore if it s dropped and hits an edge (step, table, etc) then the glass can make direct contact with something. Also the curved sides reflect sunlight in all directions, this means that the user has to go to more effort to avoid reflecting the sun into their eyes and that a passenger can more easily reflect sunlight into the eyes of a car driver. It s an impressive engineering feat to make a curved touch-screen but it doesn t do any good for users. The stylus is good as always and the screen is AMOLED so it doesn t waste much power when in dark mode. There is a configuration option to display a clock all the time when the screen is locked because that apparently doesn t use much power. I haven t felt inclined to enable the always on screen but it s a nice feature for those who like such things. The VoLTE implementation is apparently a bit unusual so it s not supported by LineageOS and didn t work on Droidian for the small amount of time that Droidian supported it. Generally this phone is quite nice hardware it s just a pity that it demonstrates all of the downsides to buying a non-Pixel phone.

Russ Allbery: podlators v6.0.2

podlators contains the Perl modules and scripts used to convert Perl's documentation language, POD, to text and manual pages. This is another small bug fix release that is part of iterating on getting the new podlators incorproated into Perl core. The bug fixed in this release was another build system bug I introduced in recent refactorings, this time breaking the realclean target so that some generated scripts were not removed. Thanks to James E Keenan for the report. You can get the latest version from CPAN or from the podlators distribution page.

Russ Allbery: DocKnot 8.0.1

DocKnot is my static web site generator, with some additional features for managing software releases. This release fixes some bugs in the newly-added conversion of text to HTML that were due to my still-incomplete refactoring of that code. It still uses some global variables, and they were leaking between different documents and breaking the formatting. It also fixes consistency problems with how the style parameter in *.spin files was interpreted, and fixes some incorrect docknot update-spin behavior. You can get the latest version from CPAN or from the DocKnot distribution page.

Ravi Dwivedi: Kenya Visa Process

Prior to arrival in Kenya, you need to apply for an Electronic Travel Authorization (eTA) on their website by uploading all the required documents. This system is in place since Jan 2024 after the country abolished the visa system, implementing the eTA portal. The required documents will depend on the purpose of your visit, which in my case, was to attend a conference. Here is the list of documents I submitted for my eTA: Reservation means I didn t book the flights and hotels, but rather reserved them. Additionally, optional means that those documents were not mandatory to submit, but I submitted them in the Other Documents section in order to support my application. After submitting the eTA, I had to make a payment of around 35 US Dollars (approximately 3000 Indian Rupees). It took 40 hours for me to receive an email from Kenya stating that my eTA has been approved, along with an attached PDF, making this one of my smoothest experiences of obtaining travel documents to travel to a country :). An eTA is technically not a visa, but I put the word visa in the title due to familiarity with the term.

Anuradha Weeraman: Windows of Opportunity: Microsoft's Open Source Renaissance

Windows of Opportunity: Microsoft's Open Source RenaissanceTwenty years ago, it was easy to dislike Microsoft. It was the quintessential evil MegaCorp that was quick to squash competition, often ruthlessly, but in some cases slowly through a more insidious process of embracing, extending, and exterminating anything that got in the way. This was the signature personality of Ballmer-era Microsoft that also inspired and united the software freedom fighting forces that came together to safeguard things that mattered to them and were at risk.I remember the era when the Novell, SCO, and Microsoft saga cast fear, uncertainty, and doubt on the future of open Unix and Linux and on what would happen to the operating systems that we loved if the suits of Redmond prevailed. Looking back, I&aposm glad that the arc of this story has bent towards justice, and I shudder at the possibilities had it worked out differently.Looking at today&aposs Microsoft, I&aposm amazed at how much change a leader with the right vision can make to the trajectory of a company that even makes an old-school software freedom advocate as me admire and even applaud the strides it has taken in the last 10 or so years that has dramatically shifted the perception of Microsoft. The personality of the Satya-era Microsoft is one to behold. While it will take more time to win back the trust, we see the tides changing and the positivity is important for the entire industry.For Microsoft, it was TypeScript and VS Code that helped change the narrative internally which led to its internal resurgence and acceptance of open source. Its acquisition of GitHub propelled it forward within the community overnight. Its contributions to the Linux kernel and other major software projects have also been consequential in changing its public perceptions.It takes a while to claw back trust and is very easy to breach. This time, however, Microsoft seems to understand this dynamic more than it did 20 years ago. All it took was the right leadership.

Russ Allbery: podlators v6.0.1

This is a small bug-fix release to remove use of autodie from the build system for the module. podlators is included in Perl core, and at the point when it is built during the core build, the prerequisites of the autodie module are not yet met, so the module is not available. This release reverts to explicit error checking in all the files used by the build system. Thanks to James E Keenan for the report and the analysis. You can get the latest version from CPAN or the podlators distribution page.

GNU Guix patch review session for reproducibility Vagrant Cascadian will holding a Reproducible Builds session as part of the monthly Guix patch review series on July 11th at 17:00 UTC. These online events are intended to encourage everyone everyone becoming a patch reviewer and the goal of reviewing patches is to help Guix project accept contributions while maintaining our quality standards and learning how to do patch reviews together in a friendly hacking session.

Development news In Debian this month, 4 reviews of Debian packages were added, 11 were updated and 14 were removed this month adding to our knowledge about identified issues. Only one issue types was updated, though, explaining that we don t vary the build path anymore.
On our mailing list this month, Bernhard M. Wiedemann wrote that whilst he had previously collected issues that introduce non-determinism he has now moved on to discuss about mitigations , in the sense of how can we avoid whole categories of problem without patching an infinite number of individual packages . In addition, Janneke Nieuwenhuizen announced the release of two versions of GNU Mes. [ ][ ]
In openSUSE news, Bernhard M. Wiedemann published another report for that distribution.
In NixOS, with the 24.05 release out, it was again validated that our minimal ISO is reproducible by building it on a virtual machine with no access to the binary cache.
What s more, we continued to write patches in order to fix specific reproducibility issues, including Bernhard M. Wiedemann writing three patches (for qutebrowser, samba and systemd), Chris Lamb filing Debian bug #1074214 against the fastfetch package and Arnout Engelen proposing fixes to refind and for the Scala compiler [ .
Lastly, diffoscope is our in-depth and content-aware diff utility that can locate and diagnose reproducibility issues. This month, Chris Lamb uploaded two versions (270 and 271) to Debian, and made the following changes as well:
  • Drop Build-Depends on liblz4-tool in order to fix Debian bug #1072575. [ ]
  • Update tests to support zipdetails version 4.004 that is shipped with Perl 5.40. [ ]

Website updates There were a number of improvements made to our website this month, including Akihiro Suda very helpfully making the <h4> elements more distinguishable from the <h3> level [ ][ ] as well as adding a guide for Dockerfile reproducibility [ ]. In addition Fay Stegerman added two tools, apksigcopier and reproducible-apk-tools, to our Tools page.

Reproducibility testing framework The Reproducible Builds project operates a comprehensive testing framework running primarily at tests.reproducible-builds.org in order to check packages and other artifacts for reproducibility. In June, a number of changes were made by Holger Levsen, including:
  • Marking the virt(32 64)c-armhf nodes as down. [ ]
  • Granting a developer access to the osuosl4 node in order to debug a regression on the ppc64el architecture. [ ]
  • Granting a developer access to the osuosl4 node. [ ][ ]
In addition, Mattia Rizzolo re-aligned the /etc/default/jenkins file with changes performed upstream [ ] and changed how configuration files are handled on the rb-mail1 host. [ ], whilst Vagrant Cascadian documented the failure of the virt32c and virt64c nodes after initial investigation [ ].

Russ Allbery: Review: The Splinter in the Sky

Review: The Splinter in the Sky, by Kemi Ashing-Giwa
Publisher: Saga Press
Copyright: July 2023
ISBN: 1-6680-0849-1
Format: Kindle
Pages: 372
The Splinter in the Sky is a stand-alone science fiction political thriller. It is Kemi Ashing-Giwa's first novel. Enitan is from Koriko, a vegetation-heavy moon colonized by the Vaalbaran empire. She lives in the Ijebu community with her sibling Xiang and has an on-again, off-again relationship with Ajana, the Vaalbaran-appointed governor. Xiang is studying to be an architect, which requires passing stringent entrance exams to be allowed to attend an ancillary imperial school intended for "primitives." Enitan works as a scribe and translator, one of the few Korikese allowed to use the sacred Orin language of Vaalbara. In her free time, she grows and processes tea. When Xiang mysteriously disappears while she's at work, Enitan goes to Ajana for help. Then Ajana dies, supposedly from suicide. The Vaalbaran government demands a local hostage while the death is investigated, someone who will be held as a diplomatic "guest" on the home world and executed if there is any local unrest. This hostage is supposed to be the child of the local headwoman, a concept that the Korikese do not have. Seeing a chance to search for Xiang, Enitan volunteers, heading into the heart of imperial power with nothing but desperate determination and a tea set. The empire doesn't stand a chance. Admittedly, a lot of the reason why the empire doesn't stand a chance is because the author is thoroughly on Enitan's side. Before she even arrives on Gondwana, Vaalbara's home world, Enitan is recruited as a spy by the other Gondwana power and Vaalbara's long-standing enemy. Her arrival in the Splinter, the floating arcology that serves as the center of Vaalbaran government, is followed by a startlingly meteoric rise in access. Some of this is explained by being a cultural curiosity for bored nobles, and some is explained by political factors Enitan is not yet aware of, but one can see the author's thumb resting on the scales. This was the sort of book that was great fun to read, but whose political implausibility provoked "wait, that didn't make sense" thoughts afterwards. I think one has to assume that the total population of Vaalbara is much less than first comes to mind when considering an interplanetary empire, which would help explain the odd lack of bureaucracy. Enitan is also living in, effectively, the palace complex, for reasonably well-explained political reasons, and that could grant her a surprising amount of access. But there are other things that are harder to explain away: the lack of surveillance, the relative lack of guards, and the odd political structure that's required for the plot to work. It's tricky to talk about this without spoilers, but the plot rests heavily on a conspiratorial view of how government power is wielded that I think strains plausibility. I'm not naive enough to think that the true power structure of a society matches the formal power structure, but I don't think they diverge as much as people think they do. It's one thing to say that the true power brokers of society can be largely unknown to the general population. In a repressive society with a weak media, that's believable. It's quite another matter for the people inside the palace to be in the dark about who is running what. I thought that was the biggest problem with this book. Its greatest feature is the characters, and particularly the character relationships. Enitan is an excellent protagonist: fascinating, sympathetic, determined, and daring in ways that make her success more believable. Early in the book, she forms an uneasy partnership that becomes the heart of the book, and I loved everything about that relationship. The politics of her situation might be a bit too simple, but the emotions were extremely well-done. This is a book about colonialism. Specifically, it's a book about cultural looting, appropriation, and racist superiority. The Vaalbarans consider Enitan barely better than an animal, and in her home they're merciless and repressive. Taken out of that context into their imperial capital, they see her as a harmless curiosity and novelty. Enitan exploits this in ways that are entirely believable. She is also driven to incandescent fury in ways that are entirely believable, and which she only rarely can allow herself to act on. Ashing-Giwa drives home the sheer uselessness of even the more sympathetic Vaalbarans more forthrightly than science fiction is usually willing to be. It's not a subtle point, but it is an accurate one. The first two thirds of this book had me thoroughly engrossed and unable to put it down. The last third unfortunately turns into a Pok mon hunt of antagonists, which I found less satisfying and somewhat less believable. I wish there had been more need for Enitan to build political alliances and go deeper into the social maneuverings of the first part of the book, rather than gaining some deus ex machina allies who trivially solve some otherwise-tricky plot problems. The setup is amazing; the resolution felt a bit like escaping a maze by blasting through the walls, which I don't think played to the strengths of the characters and relationships that Ashing-Giwa had constructed. The advantage of that approach is that we do get a satisfying resolution and a standalone novel. The central relationship of the book is unfortunately too much of a spoiler to talk about in a review, but I thought it was the best part of the story. This is a political thriller on the surface, but I think it's heart is an unexpected political alliance with a fascinatingly tricky balance of power. I was delighted that Ashing-Giwa never allows the tension in that relationship to collapse into one of the stock patterns it so easily could have become. The Splinter in the Sky reminded me a little of Arkady Martine's A Memory Called Empire. It's not as assured or as adroitly balanced as that book, and the characters are not quite as memorable, but that's a very high bar. The political point is even sharper, and it has some of the same appeal. I had so much fun reading this book. You may need to suspend your disbelief about some of the politics, and I wish the conclusion had been a bit less brute-force, but this is great stuff. Recommended when you're in the mood for a character story in the trappings of a political thriller. Rating: 8 out of 10

Evolution of the situation In June, we have released 31 DLAs. Notable security updates in June included:
  • git: multiple vulnerabilities, which may result in privilege escalation, denial of service, and arbitrary code execution
  • sendmail: SMTP smuggling allowed remote attackers bypass SPF protection checks
  • cups: arbitrary remote code execution
Looking further afield to the broader Debian ecosystem, LTS contributor Bastien Roucari s also patched sendmail in Debian 12 (bookworm) and 11 (bullseye) in order to fix the previously mentioned SMTP smuggling vulnerability. Furthermore, LTS contributor Thorsten Alteholz provided fixes for the cups packages in Debian 12 (bookworm) and 11 (bullseye) in order to fix the aforementioned arbitrary remote code execution vulnerability. Additionally, LTS contributor Ben Hutchings has commenced work on an updated backport of Linux kernel 6.1 to Debian 11 (bullseye), in preparation for bullseye transitioning to the responsibility of the LTS (and the associated closure of the bullseye-backports repository). LTS Lucas Kanashiro also began the preparatory work of backporting parts of the rust/cargo toolchain to Debian 11 (bullseye) in order to make future updates of the clamav virus scanner possible. June was the final month of LTS for Debian 10 (as announced on the debian-lts-announce mailing list). No additional Debian 10 security updates will be made available on security.debian.org. However, Freexian and its team of paid Debian contributors will continue to maintain Debian 10 going forward for the customers of the Extended LTS offer. Subscribe right away if you sill have Debian 10 which must be kept secure (and which cannot yet be upgraded).

Petter Reinholdtsen: More than 200 orphaned Debian packages moved to git, 216 to go

In April, I started migrating orphaned Debian packages without any version control system listed in debian/control to git. This morning, my Debian QA page finally reached 200 QA packages migrated. In reality there are a few more, as the packages uploaded by someone else after my initial upload have disappeared from my QA uploads list. As I am running out of steam and will most likely focus on other parts of Debian moving forward, I hope someone else will find time to continue the migration to bring the number of orphaned packages without any version control system down to zero. Here is the updated recipe if someone want to help out. To locate packages to work on, the following one-liner can be used:
PGPASSWORD="udd-mirror" psql --port=5432 --host=udd-mirror.debian.net \
  --username=udd-mirror udd -c "select source from sources \
   where release = 'sid' and (vcs_url ilike '%anonscm.debian.org%' \
   OR vcs_browser ilike '%anonscm.debian.org%' or vcs_url IS NULL \
   OR vcs_browser IS NULL) AND maintainer ilike '%packages@qa.debian.org%' \
   order by random() limit 10;"
Pick a random package from the list and run the latest edition of the script debian-snap-to-salsa with the package name as the argument to prepare a git repository with the existing packaging. This will download old Debian packages from snapshot.debian.org. Note that very recent uploads will not be included, so check out the package on tracker.debian.org. Next, run gbp buildpackage --git-ignore-new to verify that the package build as it should, and then visit https://salsa.debian.org/debian/ and make sure there is not already a git repository for the package there. I also did git log -p debian/control and look for vcs entries to check if the package used to have a git repository on Alioth, and see if it can be a useful starting point moving forward. If all this check out, I created a new gitlab project below the Debian group on salsa, push the package source there and upload a new version. I tend to also ensure build hardening is enabled, if it prove to be easy, and check if I can easily fix any lintian issues or bug reports. If the process took more than 20 minutes, I dropped it and moved on to another package. If I found patches in debian/patches/ that were not yet passed upstream, I would send an email to make sure upstream know about them. This has proved to be a valuable step, and caused several new releases for software that initially appeared abandoned. :) As usual, if you use Bitcoin and want to show your support of my activities, please send Bitcoin donations to my address 15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b.

Russ Allbery: podlators v6.0.0

podlators is the collection of Perl modules and front-end scripts that convert POD documentation to *roff manual pages or text, possibly with formatting intended for pagers. This release continues the simplifications that I've been doing in the last few releases and now uniformly escapes - characters and single quotes, disabling all special interpretation by *roff formatters and dropping the heuristics that were used in previous versions to try to choose between possible interpretations of those characters. I've come around to the position that POD simply is not semantically rich enough to provide sufficient information to successfully make a more nuanced conversion, and these days Unicode characters are available for authors who want to be more precise. This version also drops support for Perl versions prior to 5.12 and switches to semantic versioning for all modules. I've added a v prefix to the version number, since that is the convention for Perl module versions that use semantic versioning. This release also works around some changes to the man macros in groff 1.23.0 to force persistent ragged-right justification when formatted with nroff and fixes a variety of other bugs. You can get the latest release from CPAN or from the podlators distribution page.

Petter Reinholdtsen: Some notes from the 2024 LinuxCNC Norwegian developer gathering

The Norwegian The LinuxCNC developer gathering 2024 is over. It was a great and productive weekend, and I am sad that it is over. Regular readers probably still remember what LinuxCNC is, but her is a quick summary for those that forgot? LinuxCNC is a free software system for numerical control of machines such as milling machines, lathes, plasma cutters, routers, cutting machines, robots and hexapods. It eats G-code and produce motor movement and other changes to the physical world, while reading sensor input. I am not quite sure about the total head count, as not all people were present at the gathering the entire weekend, but I believe it was close to 10 people showing their faces at the gathering. The "hard core" of the group, who stayed the entire weekend, were two from Norway, two from Germany and one from England. I am happy with the outcome from the gathering. We managed to wrap up a new stable LinuxCNC release 2.9.3 and even tested it on real hardware within minutes of the release. The release notes for 2.9.3 are still being written, but should show up on on the project site in the next few days. We managed to go through around twenty pull requests and merge then into either the stable release (2.9) or the development branch (master). There are still around thirty pull requests left to process, so we are not out of work yet. We even managed to fix/improve a slightly worn lathe, and experiment with running a mechanical clock using G-code. The evening barbeque worked well both on Saturday and Sunday. It is quite fun to light up a charcoal grill using compressed air. Sadly the weather was not the best, so we stayed indoors most of the time. This gathering was made possible partly with sponsoring from both Redpill Linpro, Debian and NUUG Foundation, and we are most grateful for the support. I would also like to thank the local school for lending us some furniture, and of course the rest of the members of the organizers team, Asle and Bosse, for their countless contributions. The gathering was such success that we want to do it again next year. We plan to organize the next Norwegian LinuxCNC developer gathering at the end of June next year, the weekend Friday 27th to Sunday 29th of June 2025. I recommend you reserve the dates on your calendar today. Other related communities are also welcome to join in, for example those working on systems like FreeCAD and opencamlib, as I am sure we have much in common and sharing experiences would be very useful to all involved. We are of course looking for sponsors for this gathering already. The total budget for this gathering was around NOK 25.000 (around EUR 2.300), so our needs are quite modest. Perhaps a machine or tools company would like to help out the free software manufacturing community by sponsoring food, lodging and transport for such gathering?
