2019-05-03Prevent shutdown while running dpkgJulian Andres Klode
As long as we are running dpkg, keep an inhibitor that blocks us from shutting down. LP: #1820886
2019-03-03Add explicit message for unsupported binary signatureDavid Kalnischkies
Verifying the content of Release.gpg made us fail on binary signatures which were never officially supported (apt-secure manpage only documents only the generation of ASCII armored), but silently accepted by gpgv as we passed it on unchecked before. The binary format is complex and is itself split into old and new formats so adding support for this would not only add lots of code but also a good opportunity for bugs and dubious benefit. Reporting this issue explicitly should help repository creators figure out the problem faster than the default NODATA message hinting at captive portals. Given that the binary format has no file magic or any other clear and simple indication that this is a detached signature we guess based on the first two bits only – and by that only supporting the "old" binary format which seems to be the only one generated by gnupg in this case.

2019-02-10Fix various typos in the documentationJakub Wilk
2019-02-04Use std::to_string() for HashStringList::FileSize() getterJulian Andres Klode
This slightly improves performance, as std::to_string() (as in gcc's libstdc++) avoids a heap allocation. This is surprisingly performance critical code, so we might want to improve things further in 1.9 by manually calculating the string - that would also get rid of issues with locales changing string formatting, if any.
2019-02-04gpgv: Use buffered writes for splitting clearsigned filesJulian Andres Klode
This is safe here, as the code ensures that the file is flushed before it is being used. The next series should probably make GetTempFile() buffer writes by default.
2019-02-04Merge branch 'pu/dead-pin' into 'master'Julian Andres Klode
A pin of -32768 overrides any other, disables repo See merge request apt-team/apt!40
2019-02-01Add a Packages-Require-Authorization Release file fieldJulian Andres Klode
This new field allows a repository to declare that access to packages requires authorization. The current implementation will set the pin to -32768 if no authorization has been provided in the auth.conf(.d) files. This implementation is suboptimal in two aspects: (1) A repository should behave more like NotSource repositories (2) We only have the host name for the repository, we cannot use paths yet. - We can fix those after an ABI break. The code also adds a check to acquire-item.cc to not use the specified repository as a download source, mimicking NotSource.
2019-02-01Drop buffered writing from clearsigned message extractionDavid Kalnischkies
It is dropped in the merged code, but the extraction of the clearsigned message code was the only one who had it previously, so the short-desc explains the change from a before-after merge of the branch PoV. It would make sense to enable it, but as we aren't in a time critical paths here we can delay this for after buster to avoid problems.

2019-01-29Reuse APT::StringView more in LineBufferDavid Kalnischkies
No effective change in behaviour, just simplifying and reusing code. Suggested-By: Julian Andres Klode Gbp-Dch: Ignore
2019-01-29Rework ifs to use not instead of == false/trueDavid Kalnischkies
No change in the logic itself, just dropping "== true", replacing "== false" with not and moving lines around to make branches more obvious. Suggested-By: Julian Andres Klode Gbp-Dch: Ignore
2019-01-28Refuse files with lines unexpectedly starting with a dashDavid Kalnischkies
We support dash-encoding even if we don't really work with files who would need it as implementations are free to encode every line, but otherwise a line starting with a dash must either be a header we parse explicitly or the file is refused. This is against the RFC which says clients should warn on such files, but given that we aren't expecting any files with dash-started lines to begin with this looks a lot like a we should not continue to touch the file as it smells like an attempt to confuse different parsers by "hiding" headers in-between others. The other slightly more reasonable explanation would be an armor header key starting with a dash, but no existing key does that and it seems unlikely that this could ever happen. Also, it is recommended that clients warn about unknown keys, so new appearance is limited.
2019-01-28Use more abstraction to handle the current line bufferDavid Kalnischkies
This is C++, so we can use a bit more abstraction to let the code look a tiny bit nicer hopefully improving readability a bit. Gbp-Dch: Ignore
2019-01-28Explicitly remove the whitespaces defined by RFCDavid Kalnischkies
RFC 4880 section 7.1 "Dash-Escaped Text" at the end defines that only space and tab are allowed, so we should remove only these even if due to use complaining (or now failing) you can't really make use of it. Note that strrstrip was removing '\r\n\t ', not other whitespaces like \v or \f and another big reason to do it explicitly here now is to avoid that a future change adding those could have unintended consequences.
2019-01-24Merge and reuse tmp file handling across the boardDavid Kalnischkies
Having many rather similar implementations especially if one is exported while others aren't (and the rest of it not factored out at all) seems suboptimal.
2019-01-23Fail on non-signature lines in Release.gpgDavid Kalnischkies
The exploit for CVE-2019-3462 uses the fact that a Release.gpg file can contain additional content beside the expected detached signature(s). We were passing the file unchecked to gpgv which ignores these extras without complains, so we reuse the same line-reading implementation we use for InRelease splitting to detect if a Release.gpg file contains unexpected data and fail in this case given that we in the previous commit we established that we fail in the similar InRelease case now.
2019-01-23Fail instead of warn for unsigned lines in InReleaseDavid Kalnischkies
The warnings were introduced 2 years ago without any reports from the wild about them actually appearing for anyone, so now seems to be an as good time as any to switch them to errors. This allows rewritting the code by failing earlier instead of trying to keep going which makes the diff a bit hard to follow but should help simplifying reasoning about it.

2019-01-22Remove `register` keywordKhem Raj
In C++17 `register` keyword was removed. Current gcc 8.1.0 produces following warning if `-std=c++17` flag is used: warning: ISO C++17 does not allow 'register' storage class specifier [-Wregister] GCC almost completely ignores `register` keyword, with rare exception of `-O0` when additional copy from/to stack may be generated. For simplicity of the codebase it is better to just remove this problematic keyword where it is not strictly required.

2018-12-26configuration: Compare size first during lookupJulian Andres Klode
2018-12-04Override FileFd copy constructor to prevent copyingJulian Andres Klode
FileFd could be copied using the default copy constructor, which does not work, and then causes code to crash.
2018-11-29Use quoted tagnames in config dumpsDavid Kalnischkies
Tagnames in configuration can include spaces (and other nasties) e.g. in repository-specific configuration options due to Origin/Label potentially containing a space. The configuration file format supports parsing quoted as well as encoded spaces, but the output generated by apt-config and other places which might be feedback into apt via parsing (e.g. before calling apt-key in our gpgv method) do not quote and hence produce invalid configuration files. Changing the default to be an encoded tagname ensures that the output of dump can be used as a config file, but other users might not expect this so that is technically a backward-breaking change.
2018-11-25Fix typo reported by codespell in code commentsDavid Kalnischkies

2018-10-05Set DPKG_FRONTEND_LOCKED when running {pre,post}-invoke scriptsJulian Andres Klode
Some post-invoke scripts install packages, which fails because the environment variable is not set. This sets the variable for all three kinds of scripts {pre,post-}invoke and pre-install-pkgs, but we will only allow post-invoke at a later time. Gbp-Dch: full
2018-09-11Support multiple keyrings in sources.list Signed-ByDavid Kalnischkies
A user can specify multiple fingerprints for a while now, so its seems counter-intuitive to support only one keyring, especially if this isn't really checked or enforced and while unlikely mixtures of both should work properly, too, instead of a kinda random behaviour.
2018-05-28Use a steady clock source for progress reportingDavid Kalnischkies
Clock changes while apt is running can result in strange reports confusing (and amusing) users. Sadly, to keep the ABI for now the code is a bit more ugly than it would need to be.
2018-05-11don't try SRV requests based on IP addressesDavid Kalnischkies
IP addresses are by definition not a domain so in the best case the requests will just fail; we can do better than that on our own.

2018-04-13zstd: Implement support for multi-frame filesJulian Andres Klode
This implements support for multi frame files while keeping error checking for unexpected EOF working correctly. Files with multiple frames are generated by pzstd, for example.
2018-04-13Implement compression level handling for zstdJulian Andres Klode
This is a simplified variant of the code for xz, adapted to support multiple digit integers.
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.
