2019-02-26hashes: Remove deprecated functionsJulian Andres Klode
This keeps the members in the class, but makes them private. We want to migrate to libgcrypt eventually, since we already use libgcrypt through gpgv anyway.

2019-02-26Bump SONAMEs in preparation for ABI breaksJulian Andres Klode
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.
2019-02-04Detect function multiversioning and sse4.2/crc32, enables i386Julian Andres Klode
This fixes the build on kfreebsd-amd64, and due to the detection of sse4.2, should also enable the sse4.2 on i386.
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.
2019-02-01Introduce experimental 'never' pinning for sourcesJulian Andres Klode
This allows disabling a repository by pinning it to 'never', which is internally translated to a value of -32768 (or whatever the minimum of short is). This overrides any other pin for that repository. It can be used to make sure certain sources are never used; for example, in unattended-upgrades. To prevent semantic changes to existing files, we substitute min + 1 for every pin-priority: <min>. This is a temporary solution, as we are waiting for an ABI break. To add pins with that value, the special Pin-Priority "never" may be used for now. It's unclear if that will persist, or if the interface will change eventually.
2019-02-01Merge branch 'pu/refuseunsignedlines' into 'master'Julian Andres Klode
Fail if InRelease or Release.gpg contain unsigned lines See merge request apt-team/apt!45
2019-02-01Step over empty sections in TagFiles with commentsDavid Kalnischkies
Implementing a parser with recursion isn't the best idea, but in practice we should get away with it for the time being to avoid needless codechurn. Closes: #920317 #921037
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.

2019-01-31Merge branch 'pu/verify-method-messages-2' into 'master'Julian Andres Klode
Verify data being sent by methods in SendMessage() See merge request apt-team/apt!48
2019-01-31Disable deprecated methods (ftp, rsh, ssh) by defaultJulian Andres Klode
These methods are not supposed to be used anymore, they are not actively maintained and may hence contain odd bugs. Fixes !49
2019-01-30Verify data being sent by methods in SendMessage()Julian Andres Klode
As a follow-up for CVE-2019-3462, add checks similar to those for redirect to the central SendMessage() function. The checks are a bit more relaxed for values - they may include newlines and unicode characters (newlines get rewritten, so are safe). For keys and the message header, the checks are far more strict: They may only contain alphanumerical characters, the hyphen-minus, and the horizontal space. In case the method tries to send anything else, we construct a legal 400 URI Failed response, and send that. We specifically do not include the item URI, in case it has been compromised (that would cause infinite recursion).
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.
