2019-05-10docs: add Security chapter to the documentationStefan Hajnoczi
This new chapter in the QEMU documentation covers the security requirements that QEMU is designed to meet and principles for securely deploying QEMU. It is just a starting point that can be extended in the future with more information.

2018-08-16docs: add guidance on configuring CPU models for x86Daniel P. Berrangé
With the recent set of CPU hardware vulnerabilities on x86, it is increasingly difficult to understand which CPU configurations are good to use and what flaws they might be vulnerable to. This doc attempts to help management applications and administrators in picking sensible CPU configuration on x86 hosts. It outlines which of the named CPU models are good choices, and describes which extra CPU flags should be enabled to allow the guest to mitigate hardware flaws. Signed-off-by: Daniel P.

2018-07-16qemu-doc: Move appendix "Deprecated features" to its own fileMarkus Armbruster
Consumers of QEMU need to track feature deprecation. Keeping deprecation documentation in its own file helps in two small ways: * You can track changes the easy and obvious way, with git-log. Before, you had to resort to more complex gittery like "git-log --oneline -L '/@node Deprecated features/,/@node Supported build platforms/:qemu-doc.texi'" * It lets us use MAINTAINERS to copy interested parties on deprecation patches, so they can advise or object before they're a done deal. The next commit will do that for libvirt.

2018-07-12file-posix: specify expected filetypesJohn Snow
Adjust each caller of raw_open_common to specify if they are expecting host and character devices or not. Tighten expectations of file types upon open in the common code and refuse types that are not expected. This has two effects: (1) Character and block devices are now considered deprecated for the 'file' driver, which expects only S_IFREG, and (2) no file-posix driver (file, host_cdrom, or host_device) can open directories now. I don't think there's a legitimate reason to open directories as if they were files. This prevents QEMU from opening and attempting to probe a directory inode, which can break in exciting ways. One of those ways is lseek on ext4/xfs, which will return 0x7fffffffffffffff as the file size instead of EISDIR. This can coax QEMU into responding with a confusing "file too big" instead of "Hey, that's not a file".

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.

2018-06-28Deprecate the -enable-hax optionThomas Huth
We currently have got three ways of turning on the HAX accelerator: "-machine accel=hax", "-accel hax" and "-enable-hax". That's really confusing and overloaded. Since "-accel" is our preferred way to enable an accelerator nowadays, and "-accel hax" is even less to type than "-enable-hax", let's deprecate the "-enable-hax" option now. Note: While "-enable-kvm" is available since a long time and can hardly be removed since it is used in a lot of upper layer tools and scripts, the "-enable-hax" option is still rather new and not very widespread yet, so I think that it should be OK if we remove this in a couple of releases again (we'll see whether someone complains after seeing the deprecation message - then we could still reconsider to keep it if there a well-founded reasons).

2018-05-04qapi: deprecate CpuInfoFast.archLaszlo Ersek
The TARGET_BASE_ARCH values from "configure" don't all map to the @CpuInfoArch enum constants; in particular "s390x" from the former does not match @s390 in the latter. Clients are known to rely on the @s390 constant specifically, so we can't change it silently. Instead, deprecate the @CpuInfoFast.@arch member (in favor of @CpuInfoFast.@target) using the regular deprecation process. (No deprecation reminder is added to sysemu_target_to_cpuinfo_arch(): once @CpuInfoFast.@arch is removed, the assignment expression that calls sysemu_target_to_cpuinfo_arch() from qmp_query_cpus_fast() will have to disappear; in turn the static function left without callers will also break the build, thus it'll have to go.)

2018-03-06balloon: Fix documentation of the --balloon parameter and deprecate itThomas Huth
There are two issues with the documentation of the --balloon parameter: First, "--balloon none" is simply doing nothing. Even if a machine had a balloon device by default, this option is not disabling anything, it is simply ignored. Thus let's simply drop this option from the documentation to avoid to confuse the users (but keep the code in vl.c for backward compatibility). Second, the documentation claims that "--balloon virtio" is the default mode, but this is not true anymore since commit 382f074371f7dc32a34. Since that commit, the option also has no real use case anymore, since you can simply use "--device virtio-balloon" nowadays instead. Thus to simplify our complex parameter zoo a little bit, let's deprecate the the parameter now and tell the user to use "--device virtio-balloon" instead.

2018-03-06Document --rtc-td-hack, --localtime and --startdate as deprecatedThomas Huth
These options have been marked in a comment in qemu-options.hx as deprecated in 2009 already (see commit 1ed2fc1fa35fadc0d6), but we never informed the users about these deprecations. Let's catch up on that omission now.

2018-03-06scsi: Remove automatic creation of SCSI controllers with -drive if=scsiThomas Huth
Automatic creation of SCSI controllers for "-drive if=scsi" for x86 machines was quite a bad idea (see description of commit f778a82f0c179 for details). This is marked as deprecated since QEMU v2.9.0, and as far as I know, nobody complained that this is still urgently required anymore. Time to remove this now.

2018-03-06Remove the deprecated -tdf optionThomas Huth

2018-03-05net: Remove the deprecated 'host_net_add' and 'host_net_remove' HMP commandsThomas Huth
They are deprecated since QEMU v2.10, and so far nobody complained that these commands are still necessary for any reason - and since you can use 'netdev_add' and 'netdev_remove' instead, there also should not be any real reason. Since they are also standing in the way for the upcoming 'vlan' clean-up, it's now time to remove them.

2018-03-05net: Remove the deprecated way of dumping network packetsThomas Huth
"-net dump" has been marked as deprecated since QEMU v2.10, since it only works with the deprecated 'vlan' parameter (or hubs). Network dumping should be done with "-object filter-dump" nowadays instead. Since nobody complained so far about the deprecation message, let's finally get rid of "-net dump" now.

2018-02-13block: maintain persistent disabled bitmapsVladimir Sementsov-Ogievskiy
To maintain load/store disabled bitmap there is new approach: - deprecate @autoload flag of block-dirty-bitmap-add, make it ignored - store enabled bitmaps as "auto" to qcow2 - store disabled bitmaps without "auto" flag to qcow2 - on qcow2 open load "auto" bitmaps as enabled and others as disabled (except in_use bitmaps) Also, adjust iotests 165 and 176 appropriately.
