2015-08-27Do not parse Status fields from remote sourcesJulian Andres Klode
This could allow an attacker to mark a package as installed in a remote package index, as long as the package was not listed in the dpkg status file. This way, an attacker could force the installation of a package during a dist-upgrade, by providing two packages in an index, an older marked as installed, and a newer - apt would "upgrade" to the newer version.
2015-04-12parse specific-arch dependencies correctly on single-arch systemsDavid Kalnischkies
On single-arch the parsing was creating groupnames like 'apt:amd64' even through it should be 'apt' and a package in it belonging to architecture amd64. The result for foreign architectures was as expected: The dependency isn't satisfiable, but for native architecture it means the wrong package (ala apt:amd64:amd64) is linked so this is also not satisfiable, which is very much not expected. No longer excluding single-arch from this codepath allows the generation of the correct links, which still link to non-exisiting packages for foreign dependencies, but natives link to the expected native package just as if no architecture was given. For negative arch-specific dependencies ala Conflicts this matter was worse as apt will believe there isn't a Conflict to resolve, tricking it into calculating a solution dpkg will refuse. Architecture specific positive dependencies are rare in jessie – the only one in amd64 main is foreign –, negative dependencies do not even exist. Neither class has a native specimen, so no package in jessie is effected by this bug, but it might be interesting for stretch upgrades. This also means the regression potential is very low. Closes: 777760
2015-04-07fix crash in order writing in pkgDPkgPM::WriteApportReport()Michael Vogt
libapt can be configured to write various bits of information to a file creating a report via apport. This is disabled by default in Debian and apport residing only in /experimental so far, but Ubuntu and other derivatives have this (in some versions) enabled by default and there is no regression potentially here. The crash is caused by a mismatch of operations vs. strings for operations, so adding the missing strings for these operations solves the problem. [commit message by David Kalnischkies] LP: #1436626
2014-12-23pass-through stdin fd instead of content if not a terminalDavid Kalnischkies
Commit 299aea924ccef428219ed6f1a026c122678429e6 fixes the problem of not logging terminal in case stdin & stdout are not a terminal. The problem is that we are then trying to pass-through stdin content by reading from the apt-process stdin and writing it to the stdin of the child (dpkg), which works great for users who can control themselves, but pipes and co are a bit less forgiving causing us to pass everything to the first child process, which if the sending part of the pipe is e.g. 'yes' we will never see the end of it (as the pipe is full at some point and further writing blocks). There is a simple solution for that of course: If stdin isn't a terminal, we us the apt-process stdin as stdin for the child directly (We don't do this if it is a terminal to be able to save the typed input in the log). Closes: 773061
2014-12-23always run 'dpkg --configure -a' at the end of our dpkg callingsDavid Kalnischkies
dpkg checks now for dependencies before running triggers, so that packages can now end up in trigger states (especially those we are not touching at all with our calls) after apt is done running. The solution to this is trivial: Just tell dpkg to configure everything after we have (supposely) configured everything already. In the worst case this means dpkg will have to run a bunch of triggers, usually it will just do nothing though. The code to make this happen was already available, so we just flip a config option here to cause it to be run. This way we can keep pretending that triggers are an implementation detail of dpkg. --triggers-only would supposely work as well, but --configure is more robust in regards to future changes to dpkg and something we will hopefully make use of in future versions anyway (as it was planed at the time this and related options were implemented). Note that dpkg currently has a workaround implemented to allow upgrades to jessie to be clean, so that the test works before and after. Also note that test (compared to the one in the bug) drops the await test as its is considered a loop by dpkg now. Closes: 769609
2014-12-23do not make PTY slave the controlling terminalDavid Kalnischkies
If we have no controlling terminal opening a terminal will make this terminal our controller, which is a serious problem if this happens to be the pseudo terminal we created to run dpkg in as we will close this terminal at the end hanging ourself up in the process… The offending open is the one we do to have at least one slave fd open all the time, but for good measure, we apply the flag also to the slave fd opening in the child process as we set the controlling terminal explicitely here. This is a regression from 150bdc9ca5d656f9fba94d37c5f4f183b02bd746 with the slight twist that this usecase was silently broken before in that it wasn't logging the output in term.log (as a pseudo terminal wasn't created). Closes: 772641
2014-11-28fix PTY interaction on linux and kfreebsdDavid Kalnischkies
We run dpkg on its own pty, so we can log its output and have our own output around it (like the progress bar), while also allowing debconf and configfile prompts to happen. In commit 223ae57d468fdcac451209a095047a07a5698212 we changed to constantly reopening the slave for kfreebsd. This has the sideeffect though that in some cases slave and master will lose their connection on linux, so that no output is passed along anymore. We fix this by having always an fd referencing the slave open (linux), but we don't use it (kfreebsd). Failing to get our PTY up and running has many (bad) consequences including (not limited to, nor all at ones or in any case) garbled ouput, no output, no logging, a (partial) mixture of the previous items, … This commit is therefore also reshuffling quiet a bit of the creation code to get especially the output part up and running on linux and the logging for kfreebsd. Note that the testcase tries to cover some cases, but this is an interactivity issue so only interactive usage can really be a good test. Closes: 765687
2014-11-28close leaking slave fd after setting up pty magicDavid Kalnischkies
The fd moves out of scope here anyway, so we should close it properly instead of leaking it which will tickle down to dpkg maintainer scripts. Closes: 767774
2014-11-10use 'best' hash for source authenticationDavid Kalnischkies
Collect all hashes we can get from the source record and put them into a HashStringList so that 'apt-get source' can use it instead of using always the MD5sum. We therefore also deprecate the MD5 struct member in favor of the list. While at it, the parsing of the Files is enhanced so that records which miss "Files" (aka MD5 checksums) are still searched for other checksums as they include just as much data, just not with a nice and catchy name. This is a cherry-pick of 1262d35 with some dirty tricks to preserve ABI. LP: 1098738

2014-10-08Update Status field values handlingGuillem Jover
Remove long obsolete (hold, hold-reinstreq, removal-failed) or just wrong (post-inst-failed vs postinst-failed) values, that have been autoconverted by dpkg at run-time to their new equivalents, so there should not be any such instance in any recent system (removal-failed since dpkg 1.1.4 in Apr 1996, hold and hold-reinstreq since dpkg 1.2.0 in May 1996). dpkg even stopped doing the mapping in 1.15.4 and 1.15.8 respectively. At the same time sort the list in the same order as they appear in the dpkg code.

2014-09-08rework PTY magic to fix stair-stepping on kfreebsdDavid Kalnischkies
A pty slave we have got from openpty can only be used for one dpkg child, if we give it to a second child on kfreebsd setting TIOCSCTTY fails causing the output to be stair-stepped from now on. By switching the code to creating a master and opening a new slave in the child for each child we can fix this glitch, so that at least the master remains stable. Closes: 759684
2014-09-08fix progress report for upgrade and reinstallDavid Kalnischkies
APT treats upgrades like installs and dpkg is very similar in this, but prints still a slightly different processing message indicating that it is really an upgrade which we hadn't parsed so far, but this wasn't really visible as we quickly moved on to a 'known' state. More problematic was the reinstall case as apt hadn't recognized this for the package name detection, so that reinstalls had no progress since we introduced MultiArch.
2014-09-02* apt-pkg/deb/dpkgpm.cc:Michael Vogt
- update string matching for dpkg I/O errors. (LP: #1363257) - properly parse the dpkg status line so that package name is properly set and an apport report is created. Thanks to Anders Kaseorg for the patch. (LP: #1353171)
2014-08-26support versioned provides as implemented by dpkgDavid Kalnischkies
APT supported versioned provides for a long while in an attempt to get it working with rpm. While this support is old, we can be relatively sure that it works as versioned provides are used internally to make Multi-Arch:foreign work. Previous versions of apt will print a warning indicating that the versioned provides is ignored, so that something which "Provides: foo (= 2)" doesn't provide anything. Note that dpkg does allow only a equals-relation in the provides line as anything else is deemed too complex. apt doesn't support anything else either and such a support would require potentially big changes. Closes: 758153

Seems this was missed somehow. Closes: #759099
2014-07-07handle moved mmap after UniqFindTagWrite callDavid Kalnischkies
A call to UniqFindTagWrite can trigger the need for a bigger mmap, which is usually done by moving it, but with this move all pointers into it become invalid (and have to be remapped). The compiler calculates the pointer before the execution of the call though, so it tries to store the returned value at the old location, resulting in a segfault. We solve this by use of a temprorary variable as we did in the other instances of this problem before. Closes: #753941

2014-05-15Never parse Version/Architecture tags in a Translation-$lang fileMichael Vogt
Version/Architecture information in a Translation-$lang file is not allowed, so don't try to parse it. This is a fix for a bugreport where a Translation-en file contained the content of the regular Packages file (probably due to local FS corruption). This lead to strange error messages on file download. Thanks to Thomas Reusch for the report.

2014-03-22ensure proper teardown in dpkg error casesDavid Kalnischkies
We have to properly close our pseudo terminals even in error cases before we call post-invoke scripts. This is done now by breaking from the dpkg calling loop instead of copying the handling, which did it in the wrong order before. This also ensures that our state file is written in error cases to record autobit and co as this was forgotten before. Closes: 738969

2014-03-13support DEB_BUILD_PROFILES and -P for build profilesDavid Kalnischkies
Inspired by the rest of the patch in 661537, but abstract the parsing of various ways of setting the build profiles more so it can potentially be reused and all apt parts have the same behaviour. Especially config options, cmdline options and environment will not be combined as proposed as this isn't APTs usual behaviour and dpkg doesn't do it either, so one overrides the other as it normally does.

The offset variable in DebSrcRecordParser was not initialized which we now do and based on it do not trigger a restart if the parser was not used yet avoiding a needless rescan of the section. Detected while working on the previous commit e62aa1dd. Both commits act as a "fix" for the bug shown in the testcase of the commit – this one here would only hide it through.
