2015-09-15ui: convert VNC server to use QCryptoTLSSessionDaniel P. Berrange
Switch VNC server over to using the QCryptoTLSSession object for the TLS session. This removes the direct use of gnutls from the VNC server code. It also removes most knowledge about TLS certificate handling from the VNC server code. This has the nice effect that all the CONFIG_VNC_TLS conditionals go away and the user gets an actual error message when requesting TLS instead of it being silently ignored. With this change, the existing configuration options for enabling TLS with -vnc are deprecated. Old syntax for anon-DH credentials: -vnc hostname:0,tls New syntax: -object tls-creds-anon,id=tls0,endpoint=server \ -vnc hostname:0,tls-creds=tls0 Old syntax for x509 credentials, no client certs: -vnc hostname:0,tls,x509=/path/to/certs New syntax: -object tls-creds-x509,id=tls0,dir=/path/to/certs,endpoint=server,verify-peer=no \ -vnc hostname:0,tls-creds=tls0 Old syntax for x509 credentials, requiring client certs: -vnc hostname:0,tls,x509verify=/path/to/certs New syntax: -object tls-creds-x509,id=tls0,dir=/path/to/certs,endpoint=server,verify-peer=yes \ -vnc hostname:0,tls-creds=tls0 This aligns VNC with the way TLS credentials are to be configured in the future for chardev, nbd and migration backends. It also has the benefit that the same TLS credentials can be shared across multiple VNC server instances, if desired. If someone uses the deprecated syntax, it will internally result in the creation of a 'tls-creds' object with an ID based on the VNC server ID. This allows backwards compat with the CLI syntax, while still deleting all the original TLS code from the VNC server. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
2015-09-15crypto: introduce new module for TLS x509 credentialsDaniel P. Berrange
Introduce a QCryptoTLSCredsX509 class which is used to manage x509 certificate TLS credentials. This will be the preferred credential type offering strong security characteristics Example CLI configuration: $QEMU -object tls-creds-x509,id=tls0,endpoint=server,\ dir=/path/to/creds/dir,verify-peer=yes The 'id' value in the -object args will be used to associate the credentials with the network services. For example, when the VNC server is later converted it would use $QEMU -object tls-creds-x509,id=tls0,.... \ -vnc 127.0.0.1:1,tls-creds=tls0 Signed-off-by: Daniel P.

2015-09-15crypto: introduce new module for TLS anonymous credentialsDaniel P. Berrange
Introduce a QCryptoTLSCredsAnon class which is used to manage anonymous TLS credentials. Use of this class is generally discouraged since it does not offer strong security, but it is required for backwards compatibility with the current VNC server implementation. Simple example CLI configuration: $QEMU -object tls-creds-anon,id=tls0,endpoint=server Example using pre-created diffie-hellman parameters $QEMU -object tls-creds-anon,id=tls0,endpoint=server,\ dir=/path/to/creds/dir The 'id' value in the -object args will be used to associate the credentials with the network services. For example, when the VNC server is later converted it would use $QEMU -object tls-creds-anon,id=tls0,.... \ -vnc 127.0.0.1:1,tls-creds=tls0 Signed-off-by: Daniel P.

2015-07-02block/iscsi: add support for request timeoutsPeter Lieven
libiscsi starting with 1.15 will properly support timeout of iscsi commands. The default will remain no timeout, but this can be changed via cmdline parameters, e.g.: qemu -iscsi timeout=30 -drive file=iscsi://... If a timeout occurs a reconnect is scheduled and the timed out command will be requeued for processing after a successful reconnect. The required API call iscsi_set_timeout is present since libiscsi 1.10 which was released in October 2013. However, due to some bugs in the libiscsi code the use is not recommended before version 1.15. Please note that this patch bumps the libiscsi requirement to 1.10 to have all function and macros defined. The patch fixes also a off-by-one error in the NOP timeout calculation which was fixed while touching these code parts.

2015-06-19semihosting: add --semihosting-config arg sub-argumentpull-target-arm-20150619Leon Alrae
Add new "arg" sub-argument to the --semihosting-config allowing the user to pass multiple input arguments separately. It is required for example by UHI semihosting to construct argc and argv. Also, update ARM semihosting to support new option (at the moment it is the only target which cares about arguments). If the semihosting is enabled and no semihosting args have been specified, then fall back to -kernel/-append. The -append string is split on whitespace before initializing semihosting.argv[1..n]; this is different from what QEMU MIPS machines' pseudo-bootloaders do (i.e. argv[1] contains the whole -append), but is more intuitive from UHI user's point of view and Linux kernel just does not care as it concatenates argv[1..n] into single cmdline string anyway.

As of commit 076b35b5a (machine: add default_ram_size to machine class) we no longer have a global default ram size, but instead machine specific defaults. When invoking qemu --help we don't know which machine you selected, so we can't tell the user the default RAM size in the help text anymore now.

2014-12-11Add the "-semihosting-config" option.Liviu Ionescu
The usual semihosting behaviour is to process the system calls locally and return; unfortuantelly the initial implementation dinamically changed the target to GDB during debug sessions, which, for the usual arm-none-eabi-gdb, is not implemented. The result was that during debug sessions the semihosting calls were discarded. This patch adds a configuration variable and an option to set it on the command line: -semihosting-config [enable=on|off,]target=native|gdb|auto This option enables semihosting and defines where the semihosting calls will be addressed, to QEMU ('native') or to GDB ('gdb'). The default is auto, which means 'gdb' during debug sessions and 'native' otherwise.

2014-11-26-machine vmport=auto: Fix handling of VMWare ioport emulation for xenDon Slutz

Changed vmport from a bool to an enum. Added the value "auto" to do the old way. Move check of xen_enabled() back to pc_init1().

2014-10-27aio / timers: De-document -clockMarkus Armbruster
Commit 6d32717 "aio / timers: Remove alarm timers" has issues: 1. It silently ignores -clock for backward compatibility. Incompatible change: -clock help no longer terminates the program. Tolerable. 2. Failed to update option documentation. In particular, -help still advises users to try -clock help for available timers. Drop all documentation on -clock. 3. The 'query-alarm-clock' example in docs/writing-commands.txt no longer works, and needs to be redone. Can't do that right now, so I just stick in a FIXME.
