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.

2019-01-22SECURITY UPDATE: content injection in http method (CVE-2019-3462)Julian Andres Klode
This fixes a security issue that can be exploited to inject arbritrary debs or other files into a signed repository as followed: (1) Server sends a redirect to somewhere%0a<headers for the apt method> (where %0a is \n encoded) (2) apt method decodes the redirect (because the method encodes the URLs before sending them out), writting something like somewhere\n <headers> into its output (3) apt then uses the headers injected for validation purposes.

2019-01-22Communicate back which key(s) were used for signingDavid Kalnischkies
Telling the acquire system which keys caused the gpgv method to succeed allows us for now just a casual check if the gpgv method really executed catching bugs like CVE-2018-0501, but we will make use of the information for better features in the following commits.
2019-01-22Refactor internal Signers information storage in gpgvDavid Kalnischkies
Having a method take a bunch of string vectors is bad style, so we change this to a wrapping struct and adapt the rest of the code brushing it up slightly in the process, which results even in a slightly "better" debug output, no practical change otherwise. Gbp-Dch: Ignore

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.

This visits dependencies of all manually installed metapackages, as determined by APT::Never-MarkAuto-Sections, and marks them as automatically installed. It can be used to clean up autoflags after a d-i install, for example.

2018-12-26debListParser: Avoid native arch lookup in ParseDependsJulian Andres Klode
We called low-level ParseDepends without an architecture each time, which means each call looked up the native architecture. Store the native architecture in the class and use that when calling low-level ParseDepends from the high-level ParseDepends(). This improves performance for a cache build from 2.7 to 2.5 seconds for me. Also avoid a call when stripping multiarch, as the native architecture is passed in.

2018-12-26cache hash: Use sse4.2 CRC32c on x86-64 where availableJulian Andres Klode
This is more than twice as fast as adler32, but could be made another 50% faster by calculating crcs for 8 byte blocks in "parallel" (without data dependency) and then combining them. But that's complicated code. Reference measurements for hashing the cache 100 times: adler32=2.46s xxhash64=0.64 xxhash32=1.12 crc32c(this)=1.10 crc32c(opt)=0.44s

2018-12-04Add support for /etc/apt/auth.conf.d/*.conf (netrcparts)Julian Andres Klode
This allows us to install matching auth files for sources.list.d files, for example; very useful. This converts aptmethod's authfd from one FileFd to a vector of pointers to FileFd, as FileFd cannot be copied, and move operators are hard.

FileFd could be copied using the default copy constructor, which does not work, and then causes code to crash.
