[Bug 1891682] Re: [MIR] sane-airscan
Alexander P, for sane-aiscane getting promoted into the Main part of Ubuntu, its Debian/Ubuntu package needs unit tests run during package build (usually triggered by one of "make test" or "make check"). Currently "make test" builds a battery of test programs but does not start any of them. We need that either there are unit tests triggered by "make test" or "make check" or a so-called autopkgtest which the build server runs after installing sane-airscan on a well-defined virtual machine. My thought here is to make some or all of your test programs being run as unit tests, meaning that "make test" does not only build them but also runs them, one after the other and exits with non-zero status if one fails. For that we need tests whose results are - Independent of the presence or absence of supported scanner devices - Independent of the presence or absence of the internet and of any content in the internet This is required as the tests will run on isolated virtual machines on the build servers for Debian and Ubuntu. Could you tell which tests of yours are fulfilling these conditions (so that we can explicitly call them during package build), or better, make "make test" run all of your tests which fulfill these conditions (skipping the ones which need devices or something in the internet). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1891682 Title: [MIR] sane-airscan To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sane-airscan/+bug/1891682/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1891682] Re: [MIR] sane-airscan
I reviewed sane-airscan 0.99.24-1 as checked into hirsute. This shouldn't be considered a full audit but rather a quick gauge of maintainability. sane-airscan is a package that provides a sane backend which supports driverless network-connected scanners. - CVE History: - No CVE history, this is a relatively new package that was only first released in December 2019 and only exists in Ubuntu since groovy. - Build-Depends - gnutls, libavahi, libxml2 and libjpeg-turbo are all depedencies - No pre/post inst/rm scripts - No init scripts - No systemd units - No dbus services - No setuid binaries - 1 binary in PATH - -rwxr-xr-x root/root175312 2021-02-08 01:49 ./usr/bin/airscan-discover - No sudo fragments - No polkit files - No udev rules - unit tests / autopkgtests - unit tests are compiled in the build log but do not appear to be run during the build - these appear to just do simple testing of image decoding, URI parsing and HTTP multipart decoding. There are also tests for the zeroconf handling and these appear to be more extensive. These should be executed during the build itself. - there are no autopkgtests - No cron jobs - Build logs are quite clean - No processes spawned - Memory management - sane-airscan is all in C so there is a fair amount of dynamic memory management - this all appears to be done quite carefully, Coverity only found a couple issues (detailed below) but in general this is quite good quality code. - File IO - Loads inifile from /etc/sane.d or from path specified in environment variable CONFIG_PATH_ENV - this appears to be quite defensive and safe - Extensive logging but this all appears safe - Environment variable usage: - CONFIG_PATH_ENV - as noted above for the path to the configuration directory - HOME - use of this is safely, checking length etc before use - this is used to be able to expand ~ in configuration settings to $HOME etc - CONFIG_ENV_AIRSCAN_DEBUG - this is used to be able to turn on debug logging - No use of privileged functions - Use of cryptography / random number sources - Uses /dev/urandom to generate random value for retransmit timer - this is not security sensitive but /dev/urandom is a good choice since this is non-blocking - Uses gnutls for SHA256 hash and TLS for HTTPS - but doesn't perform any certificate verification of the remote host - but this is expected since scanners on a local network are not going to have FQDN nor appropriately issued certificates (ie they are likely to just be self-signed) - No use of temp files - Use of networking is generally defensive but relies on dependent libraries to do parsing of image formats etc so this risk is delegated - No use of WebKit - No use of PolicyKit - No significant cppcheck results - A couple significant Coverity results which should be relatively easy to fix - I have reported these upstream at https://github.com/alexpevzner/sane-airscan/issues/131 but the two most important ones are: - airscan-http.c:1275 Type: Uninitialized pointer read (UNINIT) airscan-http.c:1261: 1. var_decl: Declaring variable "parser" without initializer. airscan-http.c:1265: 2. path: Condition "skip_line", taking true branch. airscan-http.c:1267: 3. path: Condition "s", taking true branch. airscan-http.c:1275: 4. uninit_use_in_call: Using uninitialized value "parser.data" when calling "http_parser_init". http_parser.c:2220: 4.1. read_parm_fld: Reading a parameter field. -- airscan-os.c:109 Type: String not null terminated (STRING_NULL) airscan-os.c:79: 1. string_null_argument: Function "readlink" does not terminate string "*os_progname_buf".

@gunnarhj, My own builds for sane-airscan exist for Ubuntu starting from the version 16.04, so I think that technically "backporting" is a trivial task.

Currently only sane-escl supports PDF. My PDF solution is not perfect (I use Poppler). I resumed development when I realized that sane-airscan would not merge with Sane.

Thierry, thanks for the update. That is good news and so we know that the eSCL protocol is well investigated by you and Alex and so we can improve the support for it more and more. So I hope also that Alex will take you newest additions as base to complete the eSCL part of sane-airscan, to make it a universal backend making all AirScan scanners fully working. AFAIR sane-airscan does not have all of Brightness, Threshold, Sharpen, and Contrast yet. For the devices which require PDF to work, do they work with current sane-escl and/or sane-airscan? For Scanner Applications we will be able to convert forth and back between PDF and raster formats as I have made library functions out of all CUPS filters. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1891682 Title: [MIR] sane-airscan To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sane-airscan/+bug/1891682/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1891682] Re: [MIR] sane-airscan
- What is going to happen to sane-escl? Can we remove it from sans- backends, not shipping if or separate it to demote it to universe? There are no special ./configure options to suppress a backend in sane- backends, one could build without libcurl dependency, as sane-escl needs it, but there is the risk that in later sane-backends versions libcurl is needed by something else. Or libcurl can be present on the build server due to another dependency.

Messages returned to Sane are translated though. - not a python package, no extra constraints to consider int hat regard - C package that uses dh standard tool - Team subscription is OK [Packaging red flags] OK: - Ubuntu does not carry a delta - symbols tracking not applicable for this kind of code. - d/watch is present and looks ok - Upstream update history is good - Debian/Ubuntu update history is good, but short - upstream do regular releasse (upstream tarball are created via CI) - promoting this does not seem to cause issues for MOTUs that so far maintained the package - no lintian issue - d/rules is clean and minimal [Upstream red flags] OK: - no Errors/warnings during the build - no use of sudo, gksu, pkexec, or LD_LIBRARY_PATH - no use of user nobody - no use of setuid - no important open bugs (crashers, etc) in Debian or Ubuntu - no dependency on webkit, qtwebkit, seed or libgoa-* - no embedded source copies - no upstream bug opened at this date (51 bugs opened closed, so good upstream hygiene) ** Changed in: sane-airscan (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1891682 Title: [MIR] sane-airscan To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sane-airscan/+bug/1891682/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1891682] Re: [MIR] sane-airscan
"Desktop Packages" (~desktop-package) is now also subscribed to sane- airscan. ** Description changed: Driverless Scanning --- TL;DR: sane-airscan provides perfect support for driverless scanning, making thousands of devices working Printer manufacturers have introduced driverless printing standards to allow easy use of their (usually network) printers also from mobile phones, tablets, and IoT devices and not only from desktop computers which in most cases run Windows or Mac OS. This we have made use of to be able to print on a huge amount of printers from Linux and other free software operating systems. But multi-function devices with a scanner do also allow scanning from mobile devices and have a scan standard for that. Every device which supports Apple's AirPrint supports also AirScan and AirScan means that the device either scans via eSCL (from HP and Apple) or via WSD (from Microsoft and W3C). Also of this we make use to get a wide range of devices "just" working under Linux. This covers practically any modern network multi-function device, thousands of models. Finally we can also scan on multi-function devices which are not from HP (but scanning on the HP ones gets also easier, without needing HPLIP). And we even have discovered a USB-only stand-alone scanner doing driverless scanning, the Canon Lide 400. sane-airscan is the a SANE backend for supporting this. It supports both eSCL and WSD to their full extent, especially also for scanners with extra functionality like an Automatic Document Feeder (ADF). It is designed as a universal SANE backend for high-level scanning protocols, as much of the code as possible is shared between protocols, the protocol-specific parts are small. So easily new protocols, like TWAIN Direct or IPP Scan, can get added later. IPP Scan is especially important as it will help us to make scanner drivers snappable in the future. Why not sane-escl which sane-backends already ships? TL;DR: sane-escl is deprecated in favor of sane-airscan The first approach of driverless scanning which made it into Ubuntu was the sane-escl SANE backend, as part of the sane-backends package which we already include. This was easier to get in before Feature Freeze of 20.04 back in February, not requiring to get sane-airscan through NEW and then through a MIR. Also it was unclear in that time whether sane- airscan would be integrated into sane-backends. Now a lot has changed with the time: The authors of sane-escl and sane-airscan started their projects independently both also only supporting eSCL and not yet WSD. They were competing with each other and had some different priorities in their developments. I talked with them and asked them why they would not collaborate and succeeded to make them agree with each other. Now development of sane-escl has stopped and all effort goes into sane- airscan. In addition, WSD support was added to sane-airscan and sane-airscan has matured a lot, with a lot of users reporting their devices working and the author having fixed a lot of bugs based on reports and logs from users. sane-airscan supports both WSD and eSCL, sane-escl only eSCL. sane-airscan supports ADF scanning, sane-escl only scanning from the glass. Why not add sane-airscan to sane-backends upstream? --- Tl;DR: Developemnt and release pace is much faster than of SANE, with the IPP-Scan-based scanning architecture in the future only sane-airscan and not the scanner driver arsenal of sane-backends will be needed by applications. The author of sane-airscan asked for adding his backend to sane-backends in the beginning: https://gitlab.com/sane-project/backends/-/issues/202 In the end it seems that they have settled to keep sane-airscan separate, mainly due to its much faster development pace. sane-backends is only released one or two times per yer and in these intervals a lot is happening with sane-airscan. Therefore it gets released much more often. I also think that it is good that it is separate, as soon the scanning architecture will change to allow snapping everything. Scanner drivers will get hidden in a so-called Scanner Application, an emulation of an IPP scanner. As IPP is a network protocol with only IP communication and no need of dropping driver files into certain directories of the system the scanner driver can be easily snapped this way. User Applications will only need to support IPP scanners than, nothing else. As sane- airscan will get added IPP Scan in the future, this will be the only SANE backend needed to be available, so sane-backends does not need to be installed. User Applications can also be snapped with sane-airscan include in the Snap.
