2020-12-07Prepare for 0.6.0 releasev0.6.0Konstantin Ryabitsev
I think it's time to unleash this on the wider audience. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-12-07Try all DKIM headers if failed on the firstKonstantin Ryabitsev
dkim.verify will only try the topmost DKIM-Signature header, so in case of a failure, pop the failed header and retry with the next one (if any). Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-12-07Silence some pycharm warningsKonstantin Ryabitsev
PyCharm is warning that the list item can be None, but we already check for that, so silence the warning. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-12-07Fix logic when adding trailers without DKIM sigsKonstantin Ryabitsev
If the message with a follow-up trailer did not include a DKIM signature, we didn't show it in the report for added trailers (we were still adding it to the resulting message). Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-12-04Limit slug length by 100 charactersKonstantin Ryabitsev
Some subjects are still too long and hit FS file length limits. Since they are supposed to be human-friendly anyway, limit them by 100 characters. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-12-02Move the g= hash back into the XPH headerKonstantin Ryabitsev
I didn't like it as a separate header, so move it back into the X-Patch-Hashes header, but only add it if it's present. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-12-02Fix logic on git-patch-id hash generationKonstantin Ryabitsev
We're no longer returning here, so we need to flip our logic around. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-12-02Don't give up on attestation if there's no indexKonstantin Ryabitsev
Patches created with quilt will have no indexes, so git patch-id is refusing to generate a hash for them (somehow, though why?). At any rate, don't give up on attesting these patches even without the git's patch-id. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-12-01Deal with dupe follow-up trailers sent to coverKonstantin Ryabitsev
Since we now include the message object into the followup-trailer list (for DKIM verification purposes), we no longer auto-dedupe duplicate trailers. Add some extra logic to handle that. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-12-01Fix crash when dnspython is not availableKonstantin Ryabitsev
If we don't have dnspython, then we don't have _resolver. Make sure it exists and check if it's not None before looking for hasattr. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-12-01Fix b4 ty auto-matchingKonstantin Ryabitsev
When I changed auto_locate_series to return the exact patch number in addition to the matching commit_id, I introduced an off-by-one that caused all tracked series to start matching. Reported-by: Mark Brown <broonie@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-30Fix headers generated by "b4 ty"Konstantin Ryabitsev
Make sure we always create a Date: header, and that we're not crashing when we try to parse a message without a Date: header. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-30Properly clean up temporary threadfileKonstantin Ryabitsev
Now that we always create a strict-threaded file, always clean it up after we are done. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-30If using -m, reduce local mbox to strict threadKonstantin Ryabitsev
When passing a local mbox, don't assume that it is going to contain a strict thread already -- it can be just a local mailbox via something like mbsync. This grabs actual thread from the mailbox before looking at individual messages. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-30Fix crasher in mismatched trailer handlingKonstantin Ryabitsev
We may have 3 or 4 members in the array, so don't expect always 3. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-30Display DKIM status of follow-up trailersKonstantin Ryabitsev
When displaying follow-up trailers, also indicate their DKIM status. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-25Unbreak thanks-trackingKonstantin Ryabitsev
Don't forget to increment where we are when doing "continue". Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-25Use both To: and Cc: for --cc-trailersKonstantin Ryabitsev
There doesn't seem to be much rhyme or reason for why an address would be in "To" or "Cc", so use both headers when finding Cc: trailer recipients. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-24Add --cc-trailers option to b4 amKonstantin Ryabitsev
By request, add ability to copy all addresses from the email's "Cc" header into Cc: trailers, unless they are already mentioned in some other trailer. Requested-by: Arnaldo Carvalho de Melo <acme@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-24Fix crash on incomplete series thanks trackingKonstantin Ryabitsev
Now that we do our best to track incomplete series, don't crash when we come across one. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-24Improve ty with cherrypicked subsetsKonstantin Ryabitsev
Record patch counters when we start tracking series so we properly indicate in the thank-you note which ones got applied. Additionally, indicate in the subject when we're reporting on a subset of a larger series. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-24Unquote msgid if we're getting a full https URLKonstantin Ryabitsev
If we're processing a full https URL to the message, then unquote the message ID before we use it. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-24Fix crash due to incorrect array lengthKonstantin Ryabitsev
Don't use self.expected, but actual array length when preparing attestation report. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-23Tweak display in softfail modeKonstantin Ryabitsev
Don't display failures if there are no attestations available. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-23Use correct identity in the i= fieldKonstantin Ryabitsev
We shouldn't be using the From: field, as it will not necessarily match the identity of the person submitting attestation. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-23Fix softfail/hardfail messagesKonstantin Ryabitsev
Multiple fixes for error messages displayed in softfail and hardfail modes. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-23Do not parse email if no x-patch-sigKonstantin Ryabitsev
Don't attempt to parse the email if we don't find the x-patch-sig header. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-23Be more compatible with older dkimpyKonstantin Ryabitsev
If we don't find a resolve() method in dnspython, just let dkimpy do its own lookups. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-23Add mutt-filter modeKonstantin Ryabitsev
Only works for x-patch-sig style attestation, as doing DKIM attestation requires that we unignore all headers, which just junks up the view. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-23Work with older dnspython for dkim callsKonstantin Ryabitsev
If we find an older dnspython < 2.0, don't crash but let dkim figure out how it wants to look up TXT records on its own. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-20Fix DNS lookup failureKonstantin Ryabitsev
Some DKIM keys may not list v=DKIM1. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-20Add attestation-check-dkim config optionKonstantin Ryabitsev
Make it possible to turn off dkim verification entirely, but leave other attestation modes enabled. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-20Fix in-header attestation codeKonstantin Ryabitsev
We've moved some constant declarations around, so fix the code to look for them in the right places. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-20Fix signature verification for b4 prKonstantin Ryabitsev
We moved pgp sig verification code around, so fix it for the invocation in b4 pr. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-20Add very simple dkim key cachingKonstantin Ryabitsev
We're still spending too much time in dns lookups, even though they are supposed to be cached. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-20Add initial support for DKIM attestationKonstantin Ryabitsev
Now that vger is doing a much better job preserving DKIM signatures, it makes sense to teach b4 to check those. It's still failing for most mailman lists, but those are fewer than vger sources. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-17Remove standalone attverify commandKonstantin Ryabitsev
We're only doing this as part of b4 am now, so remove the obsolete attverify command. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-17Fix crasher when attempting a 3-way prepKonstantin Ryabitsev
Don't attempt a len() on an object that may be None. This happens when there are patches prepared with a tool like quilt that don't include indexes. Reported-by: Mark Brown <broonie@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-03Use raw strings to avoid unnecessary backslashesKonstantin Ryabitsev
Use r'' strings uniformly to avoid needing to escape backslashes. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-11-03Fix handling of series with the [PATCHvX] defectMarc Zyngier
b4 tries to handle subject lines such as "[PATCHvX]" by replacing the subject line in situ, but seems to do a rather bad job of it, resulting in only the first patch of the series being picked up. Fetching <20201026134931.28246-1-mark.rutland@arm.com> does exhibit the problem. Fixing the re.sub() expression allows normal funtionalities to be restored, and the above series to be fetched. Fixes: 6bf644f14b3f ("Deal with [PATCHvX] subject") Signed-off-by: Marc Zyngier <maz@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-10-27Fix a crasher discovered in testingKonstantin Ryabitsev
Don't crash on incomplete threads when trying to carry over previous trailers. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-10-27Fix attestation code for base64-encoded messagesKonstantin Ryabitsev
We need to fix all legacy encodings before we pass an email to git-mailinfo. Additionally, even if that fails, don't crash on a missing attestation. Reported-by: Greg Kroah-Hartman <greg@kroah.com> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-10-26Create an attid for unchange patch trackingKonstantin Ryabitsev
The new attestation code did away with attid, but we still use it for tracking unchanged patches between series. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-10-19Fix Link: and Cc: trailer recognitionKonstantin Ryabitsev
Link is a non-person trailer, so should be recognized as such. Cc is a person-trailer but we always expected that to include <> surrounding the address, which is not correct in all cases. Reported-by: Greg Kroah-Hartman <greg@kroah.com> Reported-by: Johan Hovold <johan@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-10-02Fix header encoding introduced by earlier fixKonstantin Ryabitsev
It seems we don't have much control over what as_bytes() does, so switch to using as_string(), setting our policy, and making sure that content-transfer-encoding is set to 8bit. Reported-by: Mark Brown <broonie@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-10-02Reimplement attestation for in-header hashesKonstantin Ryabitsev
Rewrite attestation to implement in-header hashing and signing. For now, just implementing mode=pgp, but other modes are coming next. Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-10-02Fix some cherry-picking corner casesKonstantin Ryabitsev
Handle several corner cases when trying to cherrypick from incomplete series. Reported-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-10-02Don't crash when no valid patches are foundKonstantin Ryabitsev
Error out when we don't find any patches in an mbox when trying to diff series. Reported-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-10-02Use bytes when dumping to stdoutKonstantin Ryabitsev
We don't need to needlessly convert to unicode when dumping to stdout, especially when it can lead to crashers when we encounter other charsets. Reported-by: Rob Herring <robh@kernel.org> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
2020-10-01Set charset in order to generate MIME headersKonstantin Ryabitsev
Apparently, merely passing policy= doesn't generate the full set of required headers, so make sure we do set_charset('utf-8'). Reported-by: Michał Mirosław <mirq-linux@rere.qmqm.pl> Signed-off-by: Konstantin Ryabitsev <konstantin@linuxfoundation.org>
