* HADOOP-18587. Fixing jettison vulnerability of hadoop-common lib
* no need for excluding, let it come
Change-Id: Ia6e4ad351158dd4b0510dec34bbde531a60e7654
The log level can only be set on Log4J log implementations;
probes are used to downgrade to a warning when other
logging back ends are used

Even though DiskChecker.mkdirsWithExistsCheck() will create the directory tree,
it is only called *after* the enumeration of directories with available
space has completed.
Directories which don't exist are reported as having 0 space, therefore
the mkdirs code is never reached.
Adding a simple mkdirs() -without bothering to check the outcome-
ensures that if a dir has been deleted then it will be reconstructed
if possible. If it can't it will still have 0 bytes of space
reported and so be excluded from the allocation.

Expands on the comments in cluster config to tell people
they shouldn't be running a cluster without a private VLAN
in cloud, that Knox is good here, and unsecured clusters
without a VLAN are just computation-as-a-service to crypto miners

Changes method name of RPC.Builder#setnumReaders to setNumReaders()
The original method is still there, just marked deprecated.
It is the one which should be used when working with older branches.

When closing we need to wrap the flush() in a try .. finally, otherwise
when flush throws it will stop completion of the remainder of the
close activities and in particular the close of the underlying wrapped
stream object resulting in a resource leak.

Part of HADOOP-18469 and the hardening of XML/XSL parsers.
Followup to the main HADOOP-18575 patch, to improve performance when
working with xml/xsl engines which don't support the relevant attributes.
Include this change when backporting.

The kerberos RPC does not declare any restriction on
characters used in kerberos names, though
implementations MAY be more restrictive.
If the kerberos controller supports use non-conventional
principal names *and the kerberos admin chooses to use them*
this can confuse some of the parsing.
The obvious solution is for the enterprise admins to "not do that"
as a lot of things break, bits of hadoop included.
Harden the hadoop code slightly so at least we fail more gracefully,
so people can then get in touch with their sysadmin and tell them
to stop it.
This has triggered an OOM in a process which was churning through s3a fs
instances; the increased memory footprint of IOStatistics amplified what
must have been a long-standing issue with FS instances being created
and not closed()
* Makes sure instrumentation is closed when the FS is closed.
* Uses a weak reference from metrics to instrumentation, so even
if the FS wasn't closed (see HADOOP-18478), this back reference
would not cause the S3AInstrumentation reference to be retained.
* If S3AFileSystem is configured to log at TRACE it will log the
calling stack of initialize(), so help identify where the
instance is being created. This should help track down
the cause of instance leakage.

This addresses HADOOP-18521, "ABFS ReadBufferManager buffer sharing
across concurrent HTTP requests" by not trying to cancel
in progress reads.
It supercedes HADOOP-18528, which disables the prefetching.
If that patch is applied *after* this one, prefetching
will be disabled.
As well as changing the default value in the code,
core-default.xml is updated to set
fs.azure.enable.readahead = true
As a result, if Configuration.get("fs.azure.enable.readahead")
returns a non-null value, then it can be inferred that
it was set in or core-default.xml (the fix is present)
or in core-site.xml (someone asked for it).

* Exactly 1 sending thread per an RPC connection.
* If the calling thread is interrupted before the socket write, it will be skipped instead of sending it anyways.
* If the calling thread is interrupted during the socket write, the write will finish.
* RPC requests will be written to the socket in the order received.
* Sending thread is only started by the receiving thread.
* The sending thread periodically checks the shouldCloseConnection flag.
Disables block prefetching on ABFS InputStreams, by setting
fs.azure.enable.readahead to false in core-default.xml and
the matching java constant.
This prevents
HADOOP-18521. ABFS ReadBufferManager buffer sharing across concurrent HTTP requests.
Once a fix for that is committed, this change can be reverted.

Updates okhttp3 and okio so their transitive dependency on Kotlin
stdlib is free from recent CVEs.
okhttp3:okhttp => 4.10.0
okio:okio => 3.2.0
kotlin stdlib => 1.6.20
kotlin CVEs fixed:
CVE-2022-24329
CVE-2020-29582

Move construction of XML parsers in YARN
modules to using the locked-down parser factory
of HADOOP-18469.
One exception: GpuDeviceInformationParser still supports DTD resolution;
all other features are disabled.

Add to XMLUtils a set of methods to create secure XML Parsers/transformers, locking down DTD, schema, XXE exposure.
Use these wherever XML parsers are created.

Make S3APrefetchingInputStream.seek() completely lazy. Calls to seek() will not affect the current buffer nor interfere with prefetching, until read() is called.
This change allows various usage patterns to benefit from prefetching, e.g. when calling readFully(position, buffer) in a loop for contiguous positions the intermediate internal calls to seek() will be noops and prefetching will have the same performance as in a sequential read.

Also introducing a config fs.s3a.vectored.active.ranged.reads
to configure the maximum number of number of range reads a
single input stream can have active (downloading, or queued)
to the central FileSystem instance's pool of queued operations.
This stops a single stream overloading the shared thread pool.

This problem surfaced in impala integration tests
IMPALA-11592. TestLocalCatalogRetries.test_fetch_metadata_retry fails in S3 build
after the change
HADOOP-17461. Add thread-level IOStatistics Context
The actual GC race condition came with
HADOOP-18091. S3A auditing leaks memory through ThreadLocal references
The fix for this is, if our hypothesis is correct, in WeakReferenceMap.create()
where a strong reference to the new value is kept in a local variable
*and referred to later* so that the JVM will not GC it.
Along with the fix, extra assertions ensure that if the problem is not fixed,
applications will fail faster/more meaningfully.

While merging the ranges in CheckSumFs, they are rounded up based on the
value of checksum bytes size which leads to some ranges crossing the EOF
thus they need to be fixed else it will cause EOFException during actual reads.

* This PR adds an option
use.platformToolsetVersion that
makes the build systems to use
this platform toolset version.
* This also makes sure that
win-vs-upgrade.cmd does not get
executed when the
use.platformToolsetVersion
option is specified.
