We are converting to std::string anyway by passing to
istringstream, and this removes the need for .c_str()
in callers.

Currently CONNECT requests use the name of the proxy as Host value, instead of
the origin server's name.
According to RFC 2616 "The Host field value MUST represent the naming authority
of the origin server or gateway given by the original URL."
The current implementation causes problems with some proxy vendors. This
commit fixes this.

Allow to satisfy dependency strings supplied on
the command line, optionally prefixed with
"Conflicts:" to satisfy them like Conflicts.
Build profiles and architecture restriction lists,
as used in build dependencies, are supported as
well.
Compared to build-dep, build-essential is not
installed automatically, and installing of recommended
packages follows the global default, which defaults
to yes.

This ensures that we do not accidentally stop overriding a

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.

A pin of -32768 overrides any other, disables repo
See merge request apt-team/apt!40
|
|
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.
|
|
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.

Fail if InRelease or Release.gpg contain unsigned lines

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

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.

|
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.
|
|
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.
|
|
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.

Report keys used to sign file from gpgv method to acquire system
See merge request apt-team/apt!44
|
|
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.

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.
|
|
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.

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.

Use quoted tagnames in config dumps

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.

The filename can be overridden, but sometimes it is useful to do it only
for the directory-part of the filename – e.g. if you want to let a flat
archive directory (like /var/cache/apt/archives) serve a pool-based
request like /pool/a/apt_version.deb.

We sometimes autogenerate HTML pages e.g. for listing files in a
directory or for various error codes. If this would be a serious
webserver this would be a security problem (althrough a bit hard to
exploit), but as it is not shipped and intended to be used by our
testcases only the world hasn't ended & we can ignore it for
changelog and fix it for brownie points.

Browsing pages served via aptwebserver is working better if we tell the
browser the Content-Type which for this simple usecase we can just do by
guessing based on the file extension – and because hardcoding a list
would be boring we just reuse the mime.types data from mime-support if
available and allow it to be overridden by files and config.

The implementation of "apt-cache show" (not "apt show") incorrectly
resets the currently used parser if the record itself and the
description to show come from the same file (as it is the case if no
Translation-* files are available e.g. after debootstrap).
The code is more complex than you would hope to support some rather
unusual setups involving Descriptions and their translations as tested
for by ./test-bug-712435-missing-descriptions as otherwise this could
be a one-line change.

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.
|
|
If we limit a file to be signed by a certain key it should usually
accept also being signed by any of this keys subkeys instead of
requiring each subkey to be listed explicitly. If the later is really
wanted we support now also the same syntax as gpg does with appending an
exclamation mark at the end of the fingerprint to force no mapping.
|
|
We are seeing 'processing' messages from dpkg first, so it makes sense
to translate them to "Preparing" messages instead of using "Installing"
and co to override these shortly after with the "Preparing" messages.
The difference isn't all to visible as later messages tend to linger far
longer in the display than the ealier ones, but at least in a listing it
seems more logical.
|
|
The progress reporting relies on parsing the status reports of
dpkg which used to repeat being in the same state multiple times
in the same run, but by fixing #365921 it will stop doing so.
The problem is in theory just with 'config-files' in case we do purge as
this (can) do remove + purge in one step, but we remove this also for
the unpack + configure combination althrough we handle these currently
in two independent dpkg calls.
|
|
It is an uphill battle to "reset" the environment to a clean state
without making it needlessly hard to use 'good' environment variables,
so we just try a little harder here without really trying for
completeness.

cppcheck reports: (error) Iterator 't' used after element has been erased.
The loop is actually fashioned to deal with this (not in the most
efficient way, but in simplest and speed isn't really a concern here)
IF this codepath had a "break" at the end… so I added one.
Note that the tests aren't failing before (and hopefully after) the
change as the undefined behavior we encounter is too stable.
