2019-02-26authz: delete existing ACL implementationDaniel P. Berrange
The 'qemu_acl' type was a previous non-QOM based attempt to provide an authorization facility in QEMU. Because it is non-QOM based it cannot be created via the command line and requires special monitor commands to manipulate it. The new QAuthZ subclasses provide a superset of the functionality in qemu_acl, so the latter can now be deleted. The HMP 'acl_*' monitor commands are converted to use the new QAuthZSimple data type instead in order to provide temporary backwards compatibility.

2018-11-19io: return 0 for EOF in TLS session read after shutdownDaniel P. Berrangé
GNUTLS takes a paranoid approach when seeing 0 bytes returned by the underlying OS read() function. It will consider this an error and return GNUTLS_E_PREMATURE_TERMINATION instead of propagating the 0 return value. It expects apps to arrange for clean termination at the protocol level and not rely on seeing EOF from a read call to detect shutdown. This is to harden apps against a malicious 3rd party causing termination of the sockets layer. This is unhelpful for the QEMU NBD code which does have a clean protocol level shutdown, but still relies on seeing 0 from the I/O channel read in the coroutine handling incoming replies. The upshot is that when using a plain NBD connection shutdown is silent, but when using TLS, the client spams the console with Cannot read from TLS channel: Broken pipe The NBD connection has, however, called qio_channel_shutdown() at this point to indicate that it is done with I/O. This gives the opportunity to optimize the code such that when the channel has been shutdown in the read direction, the error code GNUTLS_E_PREMATURE_TERMINATION gets turned into a '0' return instead of an error.

2018-07-03crypto: Implement TLS Pre-Shared Keys (PSK).Richard W.M. Jones
Pre-Shared Keys (PSK) is a simpler mechanism for enabling TLS connections than using certificates. It requires only a simple secret key: $ mkdir -m 0700 /tmp/keys $ psktool -u rjones -p /tmp/keys/keys.psk $ cat /tmp/keys/keys.psk rjones:d543770c15ad93d76443fb56f501a31969235f47e999720ae8d2336f6a13fcbc The key can be secretly shared between clients and servers. Clients must specify the directory containing the "keys.psk" file and a username (defaults to "qemu"). Servers must specify only the directory. Example NBD client: $ qemu-img info \ --object tls-creds-psk,id=tls0,dir=/tmp/keys,username=rjones,endpoint=client \ --image-opts \ file.driver=nbd,file.host=localhost,file.port=10809,file.tls-creds=tls0,file.export=/ Example NBD server using qemu-nbd: $ qemu-nbd -t -x / \ --object tls-creds-psk,id=tls0,endpoint=server,dir=/tmp/keys \ --tls-creds tls0 \ image.qcow2 Example NBD server using nbdkit: $ nbdkit -n -e / -fv \ --tls=on --tls-psk=/tmp/keys/keys.psk \ file file=disk.img Signed-off-by: Richard W.M.

2018-06-29glib: bump min required glib library version to 2.40Daniel P. Berrangé
Per supported platforms doc[1], the various min glib on relevant distros is: RHEL-7: 2.50.3 Debian (Stretch): 2.50.3 Debian (Jessie): 2.42.1 OpenBSD (Ports): 2.54.3 FreeBSD (Ports): 2.50.3 OpenSUSE Leap 15: 2.54.3 SLE12-SP2: 2.48.2 Ubuntu (Xenial): 2.48.0 macOS (Homebrew): 2.56.0 This suggests that a minimum glib of 2.42 is a reasonable target. The GLibC compile farm, however, uses Ubuntu 14.04 (Trusty) which only has glib 2.40.0, and this is needed for testing during merge. Thus an exception is made to the documented platform support policy to allow for all three current LTS releases to be supported. Docker jobs that not longer satisfy this new min version are removed.

2017-07-11block: pass option prefix down to crypto layerDaniel P. Berrange
While the crypto layer uses a fixed option name "key-secret", the upper block layer may have a prefix on the options. e.g. "encrypt.key-secret", in order to avoid clashes between crypto option names & other block option names. To ensure the crypto layer can report accurate error messages, we must tell it what option name prefix was used.
