tevent: rely on epoll_create1() for epoll interface
Prefer epoll_create1(2) over epoll_create(2) and
always require the former to use epoll(7) interface,
thus saving extra fcntl(2) call to set FD_CLOEXEC.

tests/krb5: Add PK-INIT testing framework
To run these tests standalone, you will need the certificate and private
key of the Certificate Authority. These can be specified together in the
same file with the environment variable CA_CERT, or the private key may
be specified in its own file with CA_PRIVATE_KEY.
If either of these files are encrypted, you can specify the password in
the environment variable CA_PASS.
These tests create a new certificate for the user account, signed with
the private key of the Certificate Authority. We negotiate the reply key
with either of the public-key and Diffie-Hellman PK-INIT variants, and
use the reply key to decrypt the enc-part in the response. We also check
that the KDC’s signatures are valid.
Most of the failures with the Heimdal KDC are due to the wrong nonce
being returned in the reply compared to Windows, which issue is simple
enough to correct.
An example command line for manual testing against Windows:
SMB_CONF_PATH=ad_dc.conf KRB5_CONFIG=krb5.conf SERVICE_USERNAME=win2k19-dc.example.com ADMIN_USERNAME=Administrator ADMIN_PASSWORD=locDCpass ADMIN_KVNO=1 FOR_USER=Administrator USERNAME=Administrator PASSWORD=locDCpass DC_SERVER=win2k19-dc.example.com SERVER=win2k19-dc.example.com DOMAIN=example REALM=example.com PYTHONPATH=bin/python STRICT_CHECKING=1 FAST_SUPPORT=1 CLAIMS_SUPPORT=1 COMPOUND_ID_SUPPORT=1 TKT_SIG_SUPPORT=1 FULL_SIG_SUPPORT=1 GNUTLS_PBKDF2_SUPPORT=1 EXPECT_PAC=1 EXPECT_EXTRA_PAC_BUFFERS=1 CHECK_CNAME=1 CHECK_PADATA=1 KADMIN_IS_TGS=0 FORCED_RC4=1 DEFAULT_ETYPES=36 CA_CERT=./win2k19-ca.pfx CA_PASS=1234 python3 python/samba/tests/krb5/pkinit_tests.py
To set up windows for this I first installed an Certificate Authority with an Enterprise CA.
Then I exported the private key and certificate of the CA:
1. go into the Certification Authority snap-in for the relevant computer,
2. right-clicking the CA
3. clicking ‘All Tasks’ → ‘Back up CA...’
4. and exporting the private key and CA certificate.
(I downloaded the resulting file via smbclient).
After setting up an Enterprise CA, I also needed to edit the domain
controller GPO to enable auto-enrollment, otherwise Windows would
refuse to accept as legitimate any certificates provided by the client.
That can be done by first enabling the policy:
‘Computer Configuration/Policies/Windows Settings/Security Settings/Public Key Policies/Certificate Services Client — Auto-Enrollment’,
and then ticking both ‘Renew expired certificates…’ and ‘Update certificates…’)

librpc/nbt: Avoid reading invalid member of union
WACK packets use the ‘data’ member of the ‘nbt_rdata’ union, but they
claim to be a different type — NBT_QTYPE_NETBIOS — than would normally
be used with that union member. This means that if rr_type is equal to
NBT_QTYPE_NETBIOS, ndr_push_nbt_res_rec() has to guess which type the
structure really is by examining the data member. However, if the
structure is actually of a different type, that union member will not be
valid and accessing it will invoke undefined behaviour.
To fix this, eliminate all the guesswork and introduce a new type,
NBT_QTYPE_WACK, which can never appear on the wire, and which indicates
that although the ‘data’ union member should be used, the wire type is
actually NBT_QTYPE_NETBIOS.
This means that as far as NDR is concerned, the ‘netbios’ member of the
‘nbt_rdata’ union will consistently be used for all NBT_QTYPE_NETBIOS
structures; we shall no longer access the wrong member of the union.

smbd: call exit_server_cleanly() to avoid panicking
The parent smdb forwards SIGTERM to its process group in order to kill all
children like the scavenger. This happens from a function registered via
atexit() which means the signal forwarding is happening very briefly before the
main smbd process exits. When exiting the pipe between smbd and scavenger is
closed which triggers a file event in the scavenger.
However, due to kernel sheduling it is possible that the file descriptor event
is received before the signal, where we call exit_server() which call
smb_panic() at the end.
Change the exit to exit_server_cleanly() and just log this event at level 2
which we already do.
