+Subject: [PATCH 1/6] fix enforcement of tcp-clients (v1)
+
+tcp-clients settings could be exceeded in some cases by
+creating more and more active TCP clients that are over
+the set quota limit, which in the end could lead to a
+DoS attack by e.g. exhaustion of file descriptors.
+
+If TCP client we're closing went over the quota (so it's
+not attached to a quota) mark it as mortal - so that it
+will be destroyed and not set up to listen for new
+connections - unless it's the last client for a specific
+interface.

+Subject: [PATCH 2/6] tcp-clients could still be exceeded (v2)
+
+the TCP client quota could still be ineffective under some
+circumstances. this change:
+
+- improves quota accounting to ensure that TCP clients are
+ properly limited, while still guaranteeing that at least one client
+ is always available to serve TCP connections on each interface.
+- uses more descriptive names and removes one (ntcptarget) that
+ was no longer needed
+- adds comments
+

+Subject: [PATCH 4/6] better tcpquota accounting and client mortality checks
+
+- ensure that tcpactive is cleaned up correctly when accept() fails.
+- set 'client->tcpattached' when the client is attached to the tcpquota.
+ carry this value on to new clients sharing the same pipeline group.
+ don't call isc_quota_detach() on the tcpquota unless tcpattached is
+ set. this way clients that were allowed to accept TCP connections
+ despite being over quota (and therefore, were never attached to the
+ quota) will not inadvertently detach from it and mess up the
+ accounting.
+- simplify the code for tcpquota disconnection by using a new function
+ tcpquota_disconnect().
+- before deciding whether to reject a new connection due to quota
+ exhaustion, check to see whether there are at least two active
+ clients. previously, this was "at least one", but that could be
+ insufficient if there was one other client in READING state (waiting
+ for messages on an open connection) but none in READY (listening
+ for new connections).
+- before deciding whether a TCP client object can to go inactive, we
+ must ensure there are enough other clients to maintain service
+ afterward -- both accepting new connections and reading/processing new
+ queries. A TCP client can't shut down unless at least one
+ client is accepting new connections and (in the case of pipelined
+ clients) at least one additional client is waiting to read.
+

+Subject: [PATCH 5/6] refactor tcpquota and pipeline refs; allow special-case
+ overrun in isc_quota
+
+- if the TCP quota has been exceeded but there are no clients listening
+ for new connections on the interface, we can now force attachment to the
+ quota using isc_quota_force(), instead of carrying on with the quota not
+ attached.
+- the TCP client quota is now referenced via a reference-counted
+ 'ns_tcpconn' object, one of which is created whenever a client begins
+ listening for new connections, and attached to by members of that
+ client's pipeline group. when the last reference to the tcpconn
+ object is detached, it is freed and the TCP quota slot is released.
+- reduce code duplication by adding mark_tcp_active() function.
+- convert counters to atomic.
+
+(cherry picked from commit 7e8222378ca24f1302a0c1c638565050ab04681b)

+Subject: [PATCH 6/6] restore allowance for tcp-clients < interfaces
+
+in the "refactor tcpquota and pipeline refs" commit, the counting
+of active interfaces was tightened in such a way that named could
+fail to listen on an interface if there were more interfaces than
+tcp-clients. when checking the quota to start accepting on an
+interface, if the number of active clients was above zero, then
+it was presumed that some other client was able to handle accepting
+new connections. this, however, ignored the fact that the current client
+could be included in that count, so if the quota was already exceeded
+before all the interfaces were listening, some interfaces would never
+listen.
+
+we now check whether the current client has been marked active; if so,
+then the number of active clients on the interface must be greater
+than 1, not 0.
+
+(cherry picked from commit 0b4e2cd4c3192ba88569dd344f542a8cc43742b5)

Drop backports, rebase a couple of patches.
This is the second last release of py 2.x; upstream support ends on
1 January 2020, there will be one final 2.x afterwards.
Note that the only thing that still needs python 2.x in oe-core is
u-boot; when the next u-boot update arrives, we should find out
where the py3 migration is for that component before merging the
update.

- (GH-16006)
-
-This change skips parsing of email addresses where domains include a "@" character, which can be maliciously used since the local part is returned as a complete address.
-
-(cherry picked from commit 8cb65d1381b027f0b09ee36bfed7f35bb4dec9a9)
-
-Excludes changes to Lib/email/_header_value_parser.py, which did not
-exist in 2.7.

+When cross compiling python, we used to need to install the Makefile, pyconfig.h

rest of python. This change allows us to point python at its own source when
building, avoiding a variety of sysroot staging issues and simplifying the main
python recipe.

-Subject: [PATCH] bpo-30458: Disallow control chars in http URLs (GH-12755)
- (GH-13154) (GH-13315)
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Disallow control chars in http URLs in urllib2.urlopen. This
-addresses a potential security problem for applications that do not
-sanity check their URLs where http request headers could be injected.
-
-Disable https related urllib tests on a build without ssl (GH-13032)
-These tests require an SSL enabled build. Skip these tests when
-python is built without SSL to fix test failures.
-
-Use httplib.InvalidURL instead of ValueError as the new error case's
-exception. (GH-13044)
-
-Backport Co-Authored-By: Miro Hrončok <miro@hroncok.cz>
-
-(cherry picked from commit 7e200e0763f5b71c199aaf98bd5588f291585619)
-
-Notes on backport to Python 2.7:
-
-* test_urllib tests urllib.urlopen() which quotes the URL and so is
- not vulerable to HTTP Header Injection.
-* Add tests to test_urllib2 on urllib2.urlopen().
-* Reject non-ASCII characters: range 0x80-0xff.

security auditing, so this isn't a valid CVE.

install_locales() here is actually operating on nativesdk and only glibc
is the default library for nativesdk, since thats what most of
desktop/server distros use, therefore bailing out based on TCLIBC is not
needed here, since nativesdk-glibc would be required for all non-glibc
targetting SDKs as well.
Fixes SDK install time error
ERROR: OE-core's config sanity checker detected a potential misconfiguration.
Either fix the cause of this error or at your own risk disable the checker (see sanity.conf).
Following is the list of potential problems / advisories:
Your system needs to support the en_US.UTF-8 locale.

CVEs that are whitelisted or were not vulnerable when there are version
comparisons were not included in the report, so alter the logic to ensure that
all relevant CVEs are in the report for completeness.

We already fetch the yearly CVE metadata and check that for updates before
downloading the full data, but we can speed up CVE checking further by only
checking the CVE metadata once an hour.

A previous optimisation was premature and resulted in false-negatives in the report.
Rewrite the checking algorithm to first get the list of potential CVEs by
vendor:product, then iterate through every matching CPE for that CVE to
determine if the bounds match or not. By doing this in two stages we can know
if we've checked every CPE, instead of accidentally breaking out of the scan too
early.

This code used to construct a single SQL statement that fetched the NVD data for
every CVE requested. For recipes such as the kernel where there are over 2000
CVEs to report this can hit the variable count limit and the query fails with
"sqlite3.OperationalError: too many SQL variables". The default limit is 999
variables, but some distributions such as Debian set the default to 250000.
As the NVD table has an index on the ID column, whilst requesting the data
CVE-by-CVE is five times slower when working with 2000 CVEs the absolute time
different is insignificant: 0.05s verses 0.01s on my machine.

Switch to recently released version 1.1 of NVD CVE JSON feed, as in
https://nvd.nist.gov/General/News/JSON-1-1-Vulnerability-Feed-Release
it is mentioned that
Due to changes required to support CVSS v3.1 scoring, the JSON
vulnerability feeds must be modified. This will require the consumers
of this data to update their internal processes. We will be providing
the JSON 1.1 schema on the data feeds page and the information below
to prepare for this transition.
...
The JSON 1.1 data feeds will be available on September 9th, 2019. At
that time the current JSON 1.0 data feeds will no longer available.
This change was tested briefly by issuing 'bitbake core-image-minimal'
with 'cve-check.bbclass' inherited via local.conf, and then comparing
the content between the resulting two
'DEPLOY_DIR_IMAGE/core-image-minimal-qemux86.cve' files, which did not
seem to contain any other change, except total of 167 entries like
CVSS v3 BASE SCORE: 0.0
were replaced with similar 'CVSS v3 BASE SCORE:' entries which had
scores that were greater than '0.0' (up to '9.8').
