* netfilter: add a netbuffer filterYang Hongyang2015-10-121-0/+17
| | | | | | | | | | | | | | | | | | | This filter is to buffer/release packets. Can be used when using MicroCheckpointing or other Remus like VM FT solutions. You can also use it to crudely simulate network delay. Doesn't actually delay individual packets, but batches them together, which is a delay of sorts. Usage: -netdev tap,id=bn0 -object filter-buffer,id=f0,netdev=bn0,queue=rx,interval=1000 NOTE: Interval is in microseconds, it can't be omitted currently, and can't be 0.

* vhost-user: add multiple queue supportChangchun Ouyang2015-09-241-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is initially based a patch from Nikolay Nikolaev. This patch adds vhost-user multiple queue support, by creating a nc and vhost_net pair for each queue. Qemu exits if find that the backend can't support the number of requested queues (by providing queues=# option). The max number is queried by a new message, VHOST_USER_GET_QUEUE_NUM, and is sent only when protocol feature VHOST_USER_PROTOCOL_F_MQ is present first. The max queue check is done at vhost-user initiation stage. We initiate one queue first, which, in the meantime, also gets the max_queues the backend supports. In older version, it was reported that some messages are sent more times than necessary. Here we came an agreement with Michael that we could categorize vhost user messages to 2 types: non-vring specific messages, which should be sent only once, and vring specific messages, which should be sent per queue. Here I introduced a helper function vhost_user_one_time_request(), which lists following messages as non-vring specific messages: VHOST_USER_SET_OWNER VHOST_USER_RESET_DEVICE VHOST_USER_SET_MEM_TABLE VHOST_USER_GET_QUEUE_NUM For above messages, we simply ignore them when they are not sent the first time.

* ui: convert VNC server to use QCryptoTLSSessionDaniel P. Berrange2015-09-151-2/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* crypto: introduce new module for TLS x509 credentialsDaniel P. Berrange2015-09-151-0/+27
| | | | | | | | | | | | | | | | | | | | | | 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.

* block/iscsi: add support for request timeoutsPeter Lieven2015-07-021-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | 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.

|/ | | | | | | | | | | | | | | | | | | | | | 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.

To enable the multi queue functionality - a new command line parameter "queues" is introduced for the vhost-user netdev.

The required ACPI v5.1 tables for ARM are: - RSDP: Initial table that points to XSDT - RSDT: Points to FADT GTDT MADT tables - FADT: Generic information about the machine - GTDT: Generic timer description table - MADT: Multiple APIC description table - DSDT: Holds all information about system devices/peripherals, pointed by FADT Signed-off-by: Shannon Zhao <zhaoshenglong@huawei.com> Signed-off-by: Shannon Zhao <shannon.zhao@linaro.org> Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Igor Mammedov <imammedo@redhat.com> Message-id: 1432522520-8068-5-git-send-email-zhaoshenglong@huawei.com Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
* net: Change help text to list -netdev instead of -net by defaultThomas Huth2015-05-271-32/+45
| | | | | | | | | | | | | | | | Looking at the output of "qemu-system-xxx -help", you easily get the impression that "-net" is the preferred way instead of "-netdev" to specify host network interface, since the "-net" option is omnipresent but the "-netdev" option is only listed as a one-liner at the end. This is ugly since "-net" is considered as legacy and even might be removed one day. Thus, this patch switches the output to explain the host network interfaces with the "-netdev" option instead, moving the old "-net" option into some few lines at the end.

| * Add the "-semihosting-config" option.Liviu Ionescu2014-12-111-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.
