test: run promtool test without docker on ubuntu/focal
before this change, we use docker for running promtools offered by
a docker image, but this is not efficient, and quite a few developers
do not want to use docker for running "make check". this change was
introduced by #39246, the reason was that, in Ceph's CI process, we
are using Ubuntu/Bionic for running "make check" jobs, but prometheus
packaged by Bionic does not offer the "test rules" command. so, to
address problem, we are using "dnanexus/promtool:2.9.2" docker image
for verifying monitoring/prometheus/alerts/test_alerts.yml.
after this change, we use prometheus packaged by debian derivatives
instead of pulling a docker image.

* install-deps.sh: partially revert 53a5816deda0874a3a37e131e9bc22d88bb2a588, as we don't need to

auth/cephx: make KeyServer::build_session_auth_info() less confusing
The second KeyServer::build_session_auth_info() overload is used only
by the monitor, for mon <-> mon authentication. The monitor passes in
service_secret (mon secret) and secret_id (-1). The TTL is irrelevant
because there is no rotation.
However the signature doesn't make it obvious. Clarify that
service_secret and secret_id are input parameters and info is the only
output parameter.
auth/cephx: cap ticket validity by expiration of "next" key
If auth_mon_ticket_ttl is increased by several times as done in
commit 522a52e6c258 ("auth/cephx: rotate auth tickets less often"),
active clients eventually get stuck because the monitor sends out an
auth ticket with a bogus validity. The ticket is secured with the
"current" secret that is scheduled to expire according to the old TTL,
but the validity of the ticket is set to the new TTL. As a result,
the client simply doesn't attempt to renew, letting the secrets rotate
potentially more than once. When that happens, the client first hits
auth authorizer errors as it tries to renew service tickets and when
it finally gets to renewing the auth ticket, it hits the insecure
global_id reclaim wall.
Cap TTL by expiration of "next" key -- the "current" key may be
milliseconds away from expiration and still be used, legitimately.
Do it in KeyServerData alongside key rotation code and propagate the
capped TTL to the upper layer.

auth/cephx: ignore CEPH_ENTITY_TYPE_AUTH in requested keys

of auth_mon_ticket_ttl. In the CEPHX_GET_AUTH_SESSION_KEY case, this
undue ticket immediately supersedes the actual auth ticket already
encoded in the same reply (the reply frame ends up containing two auth

auth/cephx: rotate auth tickets less often
If unauthorized global_id (re)use is disallowed, a client that has
been disconnected from the network long enough for keys to rotate
and its auth ticket to expire (i.e. become invalid/unverifiable)
would not be able to reconnect.
The default TTL is 12 hours, resulting in a 12-24 hour reconnect
window (the previous key is kept around, so the actual window can be
up to double the TTL). The setting has stayed the same since 2009,
but it also hasn't been enforced. Bump it to get a 72 hour reconnect
window to cover for something breaking on Friday and not getting fixed
until Monday.

mon: fail fast when unauthorized global_id (re)use is disallowed
When unauthorized global_id (re)use is disallowed, we don't want to
let unpatched clients in because they wouldn't be able to reestablish
their monitor session later, resulting in subtle hangs and disrupted
user workloads.
Denying the initial connect for all legacy (CephXAuthenticate < v3)
clients is not feasible because a large subset of them never stopped
presenting their ticket on reconnects and are therefore compatible with
enforcing mode: most notably all kernel clients but also pre-luminous
userspace clients. They don't need to be patched and excluding them
would significantly hamper the adoption of enforcing mode.
Instead, force clients that we are not sure about to reconnect shortly
after they go through authentication and obtain global_id. This is
done in Monitor::dispatch_op() to capture both msgr1 and msgr2, most
likely instead of dispatching mon_subscribe.
We need to let mon_getmap through for "ceph ping" and "ceph tell" to
work. This does mean that we share the monmap, which lets the client
return from MonClient::authenticate() considering authentication to be
finished and causing the potential reconnect error to not propagate to
the user -- the client would hang waiting for remaining cluster maps.
For msgr1, this is unavoidable because the monmap is sent immediately
after the final MAuthReply. But for msgr2 this is rare: most of the
time we get to their mon_subscribe and cut the connection before they
process the monmap!
Regardless, the user doesn't get a chance to start a workload since
there is no proper higher-level session at that point.
To help with identifying clients that need patching, add global_id and
global_id_status to "sessions" output.

auth/cephx: option to disallow unauthorized global_id (re)use
global_id is a cluster-wide unique id that must remain stable for the
lifetime of the client instance. The cephx protocol has a facility to
allow clients to preserve their global_id across reconnects:
(1) the client should provide its global_id in the initial handshake
message/frame and later include its auth ticket proving previous
possession of that global_id in CEPHX_GET_AUTH_SESSION_KEY request
(2) the monitor should verify that the included auth ticket is valid
and has the same global_id and, if so, allow the reclaim
(3) if the reclaim is allowed, the new auth ticket should be
encrypted with the session key of the included auth ticket to
ensure authenticity of the client performing reclaim. (The
included auth ticket could have been snooped when the monitor
originally shared it with the client or any time the client
provided it back to the monitor as part of requesting service
tickets, but only the genuine client would have its session key
and be able to decrypt.)
Unfortunately, all (1), (2) and (3) have been broken for a while:
- (1) was broken in 2016 by commit a2eb6ae3fb57 ("mon/monclient:
hunt for multiple monitor in parallel") and is addressed in patch
"mon/MonClient: preserve auth state on reconnects"
- it turns out that (2) has never been enforced. When cephx was
being designed and implemented in 2009, two changes to the protocol
raced with each other pulling it in different directions: commits 0669ca21f4f7 ("auth: reuse global_id when requesting tickets")
and fec31964a12b ("auth: when renewing session, encrypt ticket")
added the reclaim mechanism based strictly on auth tickets, while
commit 5eeb711b6b2b ("auth: change server side negotiation a bit")
allowed the client to provide global_id in the initial handshake.
These changes didn't get reconciled and as a result a malicious
client can assign itself any global_id of its choosing by simply
passing something other than 0 in MAuth message or AUTH_REQUEST
frame and not even bother supplying any ticket. This includes
getting a global_id that is being used by another client.
- (3) was broken in 2019 with addition of support for msgr2, where
the new auth ticket ends up being shared unencrypted. However the
root cause is deeper and a malicious client can coerce msgr1 into
the same. This also goes back to 2009 and is addressed in patch
"auth/cephx: ignore CEPH_ENTITY_TYPE_AUTH in requested keys".
Because (2) has never been enforced, no one noticed when (1) got
broken and we began to rely on this flaw for normal operation in
the face of reconnects due to network hiccups or otherwise. As of
today, only pre-luminous userspace clients and kernel clients are
not exercising it on a daily basis.
Bump CephXAuthenticate version and use a dummy v3 to distinguish
between legacy clients that don't (may not) include their auth ticket
and new clients. For new clients, unconditionally disallow claiming
global_id without a corresponding auth ticket. For legacy clients,
introduce a choice between permissive (current behavior, default for
the foreseeable future) and enforcing mode.
If the reclaim is disallowed, return EACCES. While MonClient does
have some provision for global_id changes and we could conceivably
implement enforcement by handing out a fresh global_id instead of
the provided one, those code paths have never been tested and there
are too many ways a sudden global_id change could go wrong.

mon/MonClient: preserve auth state on reconnects
Commit a2eb6ae3fb57 ("mon/monclient: hunt for multiple monitor in
parallel") introduced a regression where auth state (global_id and
AuthClientHandler) was no longer preserved on reconnects. The ensuing
breakage was quickly noticed and prompted a follow-on fix 8bb6193c8f53
("mon/MonClient: persist global_id across re-connecting").
However, as evident from the subject, the follow-on fix only took
care of the global_id part. AuthClientHandler is still destroyed
and all cephx tickets are discarded. A new from-scratch instance
is created for each MonConnection and CEPHX_GET_AUTH_SESSION_KEY
requests end up with CephXAuthenticate::old_ticket not populated.
The bug is in MonClient, so both msgr1 and msgr2 are affected.
This should have resulted in a similar sort of breakage but didn't
because of a much larger bug. The monitor should have denied the
attempt to reclaim global_id with no valid ticket proving previous
possession of that global_id presented. Alas, it appears that this
aspect of the cephx protocol has never been enforced. This is dealt
with in the next patch.
To fix the issue at hand, clone AuthClientHandler into each
MonConnection so that each respective CEPHX_GET_AUTH_SESSION_KEY
request gets a copy of the current auth ticket.
