Not needed for common interactions, but for some download-file
interactions it could be useful to set a specific referer as some
servers do not serve requested files otherwise.

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 << 0.8.11 was stronger than necessary, and breaks Ubuntu,
which is unable to build aptitude 0.8.11 atm (the test suite
fails since 0.8.10 in C++17 mode, only works in C++14, but
0.8.11 uses C++17 constructs).

If the server closed the connection while we're reading data, and
we end up not having any data left to write; that is, for example,
we received 0 bytes, then we did not exit before, as we only returned
success if there was data to write.
This is wrong: Obviously, if we have reached our limit, we are done
anyway. It's a bit unclear if we actually ever reached this part, but
it does make some sense wrt the bug below.

gcc 8 broke the ABI again. After they decided to switch mangling of ABI tags in return values from:
U URI::operator std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >[abi:cxx11]()
to:
U URI::operator std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >()
in gcc 7, they now removed the legacy symbol in gcc 8, causing us to break our ABI in turn
for that one operator. We need more responsible gcc developers.

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.

pkgCacheFile's destructor unlocks the system, which is confusing
if you did not open the cachefile with WithLock set. Create a private

A recent change to use chronos inadvertently replaced the
difference of new usec - old usec with new sec - old usec,
which is obviously wrong.

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.

http: Stop pipeline after close only if it was not filled before
See merge request apt-team/apt!25
|
|
It is perfectly valid behavior for a server to respond with
Connection: close eventually, even when pipelining. Turning
off pipelining due to that is wrong. For example, some Ubuntu
mirrors close the connection after 101 requests. If I have
more packages to install, only the first 101 would benefit
from pipelining.
This commit introduces a new check to only turn of pipelining
for future connections if the pipeline for this connection did
not have 3 successful fetches before, that should work quite well to
detect broken server/proxy combinations like in bug 832113.

do not suggest that 'source' and 'build-dep' arguments are binary
package names only
|
|
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.
|
|
Exiting the processing loop as soon as the dpkg process finishes might
leave status-fd lines unprocessed which wasn't much of a problem in the
past as the progress would just be slightly off, but now that we us the
information also for skipping already done tasks and generate warnings
if we didn't see all expected messages we should make sure we seem them
all. We still need to exit "early" if dpkg exited unsuccessfully/crashed
through as the (remaining) status lines we get could be incomplete.
|
|
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.

APT in 1.6 saw me rewriting the mirror:// transport method, which works
comparable to the decommissioned httpredir.d.o "just" that apt requests
a mirror list and performs all the redirections internally with all the
bells like parallel download and automatic fallback (more details in the
apt-transport-mirror manpage included in the 1.6 release).
The automatic fallback is the problem here: The intend is that if a file
fails to be downloaded (e.g. because the mirror is offline, broken,
out-of-sync, …) instead of erroring out the next mirror in the list is
contacted for a retry of the download.
Internally the acquire process of an InRelease file (works with the
Release/Release.gpg pair, too) happens in steps: 1) download file and 2)
verify file, both handled as URL requests passed around. Due to an
oversight the fallbacks for the first step are still active for the
second step, so that the successful download from another mirror stands
in for the failed verification… *facepalm*
Note that the attacker can not judge by the request arriving for the
InRelease file if the user is using the mirror method or not. If entire
traffic is observed Eve might be able to observe the request for
a mirror list, but that might or might not be telling if following
requests for InRelease files will be based on that list or for another
sources.list entry not using mirror (Users have also the option to have
the mirror list locally (via e.g. mirror+file://) instead of on a remote
host). If the user isn't using mirror:// for this InRelease file apt
will fail very visibly as intended.
(The mirror list needs to include at least two mirrors and to work
reliably the attacker needs to be able to MITM all mirrors in the list.
For remotely accessed mirror lists this is no limitation as the attacker
is in full control of the file in that case)
Fixed by clearing the alternatives after a step completes (and moving a pimpl
class further to the top to make that valid compilable code). mirror://
is at the moment the only method using this code infrastructure (for all
others this set is already empty) and the only method-independent user
so far is the download of deb files, but those are downloaded and
verified in a single step; so there shouldn't be much opportunity for
regression here even through a central code area is changed.
Upgrade instructions: Given all apt-based frontends are affected, even
additional restrictions like signed-by are bypassed and the attack in
progress is hardly visible in the progress reporting of an update
operation (the InRelease file is marked "Ign", but no fallback to
"Release/Release.gpg" is happening) and leaves no trace (expect files
downloaded from the attackers repository of course) the best course of
action might be to change the sources.list to not use the mirror family
of transports ({tor+,…}mirror{,+{http{,s},file,…}}) until a fixed
version of the src:apt packages are installed.

gpgs DETAILS documentation file declares that GOODSIG could report keyid
or fingerprint since gpg2, but for the time being it is still keyid
only. Who knows if that will ever change as that feels like an interface
break with dangerous security implications, but lets be better safe than
sorry especially as the code dealing with signed-by keyids is prepared
for this already. This code is rewritten still to have them all use the
same code for this type of problem.
