[PATCH 3/3] Core-local statistics
Summary:
This diff changes `StatisticsImpl` from a thread-local approach to a core-local one. The goal is to perform faster aggregations, particularly for applications that have many threads. There should be no behavior change.

[PATCH 2/3] core-local array type conversions
Summary:
try to clean up the type conversions and hope it passes on windows.
one interesting thing I learned is that bitshift operations are special: in `x << y`, the result type depends only on the type of `x`, unlike most arithmetic operations where the result type depends on both operands' types.

* Non-maintainer upload by the LTS Security Team.
[ Stefano Rivera ]
* Collection of minor security updates for Ceph.
* CVE-2020-27781: Privilege Escalation: User credentials could be manipulated
and stolen by Native CephFS consumers of OpenStack Manila, resulting in
potential privilege escalation. An Open Stack Manila user can request
access to a share to an arbitrary cephx user, including existing users.
The access key is retrieved via the interface drivers. Then, all users of
the requesting OpenStack project can view the access key. This enables the
attacker to target any resource that the user has access to. This can be
done to even "admin" users, compromising the ceph administrator.
* CVE-2021-20288: Potential Privilege Escalation: When handling
CEPHX_GET_PRINCIPAL_SESSION_KEY requests, ignore CEPH_ENTITY_TYPE_AUTH in
CephXServiceTicketRequest::keys.
* CVE-2020-1760: XSS: A flaw was found in the Ceph Object Gateway, where it
supports request sent by an anonymous user in Amazon S3. This flaw could
lead to potential XSS attacks due to the lack of proper neutralization of
untrusted input.
* CVE-2020-25678: Information Disclosure: ceph stores mgr module passwords
in clear text. This can be found by searching the mgr logs for grafana and
dashboard, with passwords visible.
* CVE-2019-10222: Denial of service: An unauthenticated attacker could crash
the Ceph RGW server by sending valid HTTP headers and terminating the
connection, resulting in a remote denial of service for Ceph RGW clients.
* CVE-2020-10753 and CVE-2021-3524: Header Injection: It was possible to
inject HTTP headers via a CORS ExposeHeader tag in an Amazon S3 bucket. The
newline character in the ExposeHeader tag in the CORS configuration file
generates a header injection in the response when the CORS request is
made.
* CVE-2020-12059: Denial of Service: A POST request with an invalid tagging
XML could crash the RGW process by triggering a NULL pointer exception.
* CVE-2020-1700: Denial of Service: A flaw was found in the way the Ceph RGW
Beast front-end handles unexpected disconnects. An authenticated attacker
can abuse this flaw by making multiple disconnect attempts resulting in a
permanent leak of a socket connection by radosgw. This flaw could lead to
a denial of service condition by pile up of CLOSE_WAIT sockets, eventually
leading to the exhaustion of available resources, preventing legitimate
users from connecting to the system.
* CVE-2021-3531: Denial of Service: When processing a GET Request in Ceph
Storage RGW for a swift URL that ends with two slashes it could cause the
rgw to crash, resulting in a denial of service.
* CVE-2021-3979: Loss of Confidentiality: A key length flaw was found in
Ceph Storage. An attacker could exploit the fact that the key length is
incorrectly passed in an encryption algorithm to create a non random key,
which is weaker and can be exploited for loss of confidentiality and
integrity on encrypted disks.
[ Bastien Roucariès ]
* CVE-2023-43040: A flaw was found in Ceph RGW. An unprivileged
user can write to any bucket(s) accessible by a given key
if a POST's form-data contains a key called 'bucket'
with a value matching the name of the bucket used to sign
the request. The result of this is that a user could actually
upload to any bucket accessible by the specified access key
as long as the bucket in the POST policy matches the bucket
in said POST form part. (Closes: #
