2018-03-12apt-pkg: Add support for zstdJulian Andres Klode
zstd is a compression algorithm developed by facebook. At level 19, it is about 6% worse in size than xz -6, but decompression is multiple times faster, saving about 40% install time, especially with eatmydata on cloud instances.

2018-02-19Check that Date of Release file is not in the futureJulian Andres Klode
By restricting the Date field to be in the past, an attacker cannot just create a repository from the future that would be accepted as a valid update for a repository. This check can be disabled by Acquire::Check-Date set to false. This will also disable Check-Valid-Until and any future date related checking, if any - the option means: "my computers date cannot be trusted." Modify the tests to allow repositories to be up to 10 hours in the future, so we can keep using hours there to simulate time changes.
2018-02-19ensure correct file permissions for auxfilesDavid Kalnischkies
The interesting takeaway here is perhaps that 'chmod +w' is effected by the umask – obvious in hindsight of course. The usual setup helps with hiding that applying that recursively on all directories (and files) isn't correct. Ensuring files will not be stored with the wrong permissions even if in strange umask contexts is trivial in comparison. Fixing the test also highlighted that it wasn't bulletproof as apt will automatically fix the permissions of the directories it works with, so for this test we actually need to introduce a shortcut in the code.

2018-01-03document https options in new apt-transport-https manpageDavid Kalnischkies
Same reasoning as with the previous commit for http with the added benefit of moving the hard to discover and untranslated example config into a manpage which could be translated.
2018-01-03Add rapid "happy eyeballs" connection fallback (RFC 8305)Julian Andres Klode
Try establishing connections in alternating address families in rapid intervals of 250 ms, adding more connections to the wait list until one succeeds (RFC 8305, happy eyeballs 2). It is important that WaitAndCheckErrors() waits until it has a successful connection, a time out, or all connections failed - otherwise the timing between tries might be wrong, and the final long wait might exit early because one connection failed without trying the others. Timing wise, this only works correctly on Linux, as select() counts down there. But we rely on that in some other places too, so this is not the time to fix that. Timeouts are only reported in the final long wait - the short inner waits are expected to time out more often, and multiple times, we do not want to report them.

2017-10-26Print syscall number and arch to stderr when trapped by seccompJulian Andres Klode
This should help debugging crashes. The signal handler is a C++11 lambda, yay! Special care has been taken to only use signal handler -safe functions inside there.
2017-10-22Sandbox methods with seccomp-BPF; except cdrom, gpgv, rshJulian Andres Klode
This reduces the number of syscalls to about 140 from about 350 or so, significantly reducing security risks. Also change prepare-release to ignore the architecture lists in the build dependencies when generating the build-depends package for travis. We might want to clean up things a bit more and/or move it somewhere else.
2017-07-26show a warning for Debian shutting down FTP servicesDavid Kalnischkies
We detect the effected sources by matching Release info – that has potential by-catch of repositories which have incorrect field values, but those are better fixed now anyhow. The bigger incorrectness is that this message will not only be printed for the Debian services itself but also for all mirrors not under Debian control but serving Debian like more local/private mirrors which will not (directly) shutdown. It is likely through that many of them will follow suite with less visible announcements or break downright if their upstream source disappears, so having false-positives here seems benefitial for the user in the end.

2017-06-28ask for releaseinfo change interactively in aptDavid Kalnischkies
If we have a user sitting around we can let 'apt' ask the user for a confirmation rather than print errors at the end and require the user to figure out which commandline flags are needed to confirm the changes non-interactively.
2017-06-28error in update on Release information changesDavid Kalnischkies
The value of Origin, Label, Codename and co can be used in user configuration from apts own pinning to unattended upgrades. A repository changing this values can therefore have serious effects on the behaviour of apt and other tools using these values. In a first step we will generate error messages for these changes now explaining the need for explicit confirmation and provide config options and commandline flags to accept them.
2017-06-28Introduce Acquire::AllowTLS to turn off TLS supportJulian Andres Klode
As requested by Henrique de Moraes Holschuh, here comes an option to disable TLS support. If the option is set to false, the internal TLS layer is disabled.
2017-06-26avoid explicit types for pkg counts by autoDavid Kalnischkies
Changes nothing on the program front and as the datatypes are sufficently comparable fixes no bug either, but problems later on if we ever change the types of those and prevent us using types which are too large for the values we want to store waste (a tiny bit of) resources. Gbp-Dch: Ignore

2017-01-17Read dpkg tables to handle architecture wildcardsJulian Andres Klode
Our implementation of wildcards was rudimentary. It worked for some common ones, but it was also broken: For example, armel matched any-armel, but should match any-arm. With this commit, we load the correct tables from dpkg. Supported are both triplets and quadruplet tables (the latter introduced in dpkg 1.18.11). There are some odd things we have to deal with in the cache filter for historical and API reasons: * The character "*" must be accepted as an alternative to any - in fact it may appear anywhere in the wildcard as we also allow fnmatch() style wildcard matching on the commandline. * The code might get passed an arch with a minus at the end, for example the cmdline "install apt:any-arm-" will first try to check if any-arm- is a valid architecture. We deal with this by rejecting any wildcard ending in a minus. * Triplets are actually implemented by extending them to faux quadruplets - by prepending a "base" component for the architecture tuple, and "any" if there is a wildcard component. Once we have constructed a wildcard, it is transformed into an fnmatch() expression for historical reasons. In the future, we should really get a tuple class and implement matching in a better, more explicit way. This does for now though - it passes all the test cases and accepts all things it should accept. Closes: #748936 Thanks: James Clarke <jrtc27@jrtc27.com> for the initial patch
2016-12-31allow warning generation for non-whitelisted optionsDavid Kalnischkies
The idea is simple: Each¹ Find*( call starts with a call check if the given option (with the requested type) exists in the whitelist. The whitelist is specified via our configure-index file so that we have a better chance at keeping it current. the whitelist is loaded via a special (undocumented for now) configuration stanza and if none is loaded the empty whitelist will make it so that no warnings are shown. Much needs to be done still, but that is as good a time as any to take a snapshot of the current state and release it into the wild given that it found some bugs already and has no practical effect on users. ¹ not all in this iteration, but many
2016-11-11add hidden config to set packages as Essential/ImportantDavid Kalnischkies
You can pretty much achieve the same with a local dummy package if you want to, but libapt has an inbuilt setting for essential: "apt" which can be overridden with this option as well – it could be helpful in quick tests and what not so adding this alternative shouldn't really hurt much. We aren't going to document them much through as care must be taken in regards to the binary caches as they aren't invalidated by config options alone, so the effects of old settings could still be in them, similar to the other already existing pkgCacheGen option(s). Closes: 767891 Thanks: Anthony Towns for initial patch
2016-08-06CMake: Add initial support for documentation buildingJulian Andres Klode
Build HTML docbook guides (untranslated) and manual pages (including translations). Also install the examples in the example subdirectory. Translation of docbook guides has not been implemented yet, but should be easy to do. The code also needs some cleanup to automatically detect the available translations.
2016-05-27fix and document on the fly compressor configDavid Kalnischkies
libapt allows to configure compressors to be used by its system via configuration implemented in 03bef78461c6f443187b60799402624326843396, but that was never really documented and also only partly working, which also explains why the tests weren't using it…

2015-12-02use @CHANGEPATH@ as placeholder in changelog URI templatesDavid Kalnischkies
This should make it more obvious that CHANGEPATH is a placeholder which apt will replace with a package specific path rather than a string constant. Mail-Reference: <87d1upgvaf.fsf@deep-thought.43-1.org> Mail-Archive: https://lists.debian.org/debian-dak/2015/12/msg00005.html
2015-06-15provide a public interface for acquiring changelogsDavid Kalnischkies
Provided is a specialized acquire item which given a version can figure out the correct URI to try by itself and if not provides an error message alongside with static methods to get just the URI it would try to download if it should just be displayed or similar such. The URI is constructed as follows: Release files can provide an URI template in the "Changelogs" field, otherwise we lookup a configuration item based on the "Label" or "Origin" of the Release file to get a (hopefully known) default value for now. This template should contain the string CHANGEPATH which is replaced with the information about the version we want the changelog for (e.g. main/a/apt/apt_1.1). This middleway was choosen as this path part was consistent over the three known implementations (+1 defunct), while the rest of the URI varies widely between them. The benefit of this construct is that it is now easy to get changelogs for Debian packages on Ubuntu and vice versa – even at the moment where the Changelogs field is present nowhere. Strictly better than what apt-get had before as it would even fail to get changelogs from security… Now it will notice that security identifies as Origin: Debian and pick this setting (assuming again that no Changelogs field exists). If on the other hand security would ship its changelogs in a different location we could set it via the Label option overruling Origin. Closes: 687147, 739854, 784027, 787190

2014-10-01Use Acquire::Allow{InsecureRepositories,DowngradeToInsecureRepositories}Michael Vogt
The configuration key Acquire::AllowInsecureRepositories controls if apt allows loading of unsigned repositories at all. The configuration Acquire::AllowDowngradeToInsecureRepositories controls if a signed repository can ever become unsigned. This should really never be needed but we provide it to avoid having to mess around in /var/lib/apt/lists if there is a use-case for this (which I can't think of right now).
