2017-02-16target-i386: correctly propagate retaddr into SVM helpersPaolo Bonzini7-58/+56
Commit 2afbdf8 ("target-i386: exception handling for memory helpers", 2015-09-15) changed tlb_fill's cpu_restore_state+raise_exception_err to raise_exception_err_ra. After this change, the cpu_restore_state and raise_exception_err's cpu_loop_exit are merged into raise_exception_err_ra's cpu_loop_exit_restore. This actually fixed some bugs, but when SVM is enabled there is a second path from raise_exception_err_ra to cpu_loop_exit. This is the VMEXIT path, and now cpu_vmexit is called without a cpu_restore_state before. The fix is to pass the retaddr to cpu_vmexit (via cpu_svm_check_intercept_param). All helpers can now use GETPC() to pass the correct retaddr, too.

2017-02-16Makefile: avoid leaving the temporary QEMU_PKGVERSION header fileLin Ma1-1/+5
By commit 67a1de0d, When we perform 'git pull && make && sudo make install', In 'make' stage a qemu-version.h.tmp will be generated. If the content of qemu-version.h.tmp and qemu-version.h aren't consistent, The qemu-version.h.tmp will be renamed to qemu-version.h. Because of the target FORCE, The same action will be do again in 'make install' stage. In 'make install' stage, If there is no qemu-version.h.tmp exists and we run 'make install' with sudo, The owner and group of new qemu-version.h.tmp will be privileged user/group. When we run 'make' next time, qemu-version.h.tmp can't be overwritten because of permission issue. This patch removed qemu-version.h.tmp after build to fix this issue.

2017-02-16vl: Move the cpu_synchronize_all_post_init() after generic devices ↵Dou Liyang1-2/+2
initialization At the Qemu initialization, we call the cpu_synchronize_all_post_init() to synchronize All CPU states to KVM in the ./vl.c::main(). Currently, it is called before we initialize the CPUs, which is created by "-device" command and parsed by generic devices initialization, So, these CPUs may be ignored to synchronize. The patch moves the cpu_synchronize_all_post_init func after generic devices initialization to make sure that all the CPUs can be included.

2017-02-16qemu-nbd: Implement socket activation.Richard W.M. Jones1-9/+163
Socket activation (sometimes known as systemd socket activation) allows an Internet superserver to pass a pre-opened listening socket to the process, instead of having qemu-nbd open a socket itself. This is done via the LISTEN_FDS and LISTEN_PID environment variables, and a standard file descriptor range. This change partially implements socket activation for qemu-nbd. If the environment variables are set correctly, then socket activation will happen automatically, otherwise everything works as before. The limitation is that LISTEN_FDS must be 1.

2017-02-16linux-user: Use correct types in load_symbols()Peter Maydell1-7/+15
Coverity doesn't like the code in load_symbols() which assumes it can use 'int' for a variable that might hold an offset into the guest ELF file, because in a 64-bit guest that could overflow. Guest binaries with 2GB sections aren't very likely and this isn't a security issue because we fully trust the guest linux-user binary anyway, but we might as well use the right types, which will placate Coverity. Use uint64_t to hold section sizes, and bail out if the symbol table is too large rather than just overflowing an int.

2017-02-16gdbstub: Fix vCont behaviourClaudio Imbrenda1-47/+162
When GDB issues a "vCont", QEMU was not handling it correctly when multiple VCPUs are active. For vCont, for each thread (VCPU), it can be specified whether to single step, continue or stop that thread. The default is to stop a thread. However, when (for example) "vCont;s:2" is issued, all VCPUs continue to run, although all but VCPU nr 2 are to be stopped. This patch completely rewrites the vCont parsing code. Please note that this improvement only works in system emulation mode, when in userspace emulation mode the old behaviour is preserved.

2017-02-16qemu-char: socket backend: disconnect on write errorAnton Nefedov1-0/+10
Socket backend read handler should normally perform a disconnect, however the read handler may not get a chance to run if the frontend is not ready (qemu_chr_be_can_write() == 0). This means that in virtio-serial frontend case if - the host has disconnected (giving EPIPE on socket write) - and the guest has disconnected (-> frontend not ready -> backend will not read) - and there is still data (frontend->backend) to flush (has to be a really tricky timing but nevertheless, we have observed the case in production) This results in virtio-serial trying to flush this data continiously forming a busy loop. Solution: react on write error in the socket write handler. errno is not reliable after qio_channel_writev_full(), so we may not get the exact EPIPE, so disconnect on any error but QIO_CHANNEL_ERR_BLOCK which io_channel_send_full() converts to errno EAGAIN. We must not disconnect right away though, there still may be data to read (see 4bf1cb0). Signed-off-by: Anton Nefedov <anton.nefedov@virtuozzo.com> Signed-off-by: Denis V.

2017-02-15net: Mark 'vlan' parameter as deprecatedThomas Huth1-0/+6
The 'vlan' parameter is a continuous source of confusion for the users, many people mix it up with the more common term VLAN (the link layer packet encapsulation), and even if they realize that the QEMU 'vlan' is rather some kind of network hub emulation, there is still a high risk that they configure their QEMU networking in a wrong way with this parameter (e.g. by hooking NICs together, so they get a 'loopback' between one and the other NIC). Thus at one point in time, we should finally get rid of the 'vlan' feature in QEMU. Let's do a first step in this direction by declaring the 'vlan' parameter as deprecated and informing the users to use the 'netdev' parameter instead.

2017-02-14linux-user: manage two new IFLA host message typesLaurent Vivier1-0/+2
Add QEMU_IFLA_GSO_MAX_SEGS and QEMU_IFLA_GSO_MAX_SIZE in host_to_target_data_link_rtattr(). These two messages are sent by the host kernel when we use "sudo". Found with qemu-m68k and Debian etch-m68k (sudo 1.6.8p12-4) and host kernel 4.7.6-200.fc24.x86_64 Signed-off-by: Laurent Vivier <laurent@vivier.eu> Message-Id: <1477530049-15676-1-git-send-email-laurent@vivier.eu>
2017-02-14linux-user: Fix mq_openLena Djokic1-3/+8
If fourth argument is NULL it should be passed without using lock_user function which would, in that case, return EFAULT, and system call supports passing NULL as fourth argument.

2017-02-14linux-user: Fix inotify_init1 supportLena Djokic1-1/+2
This commit adds necessary conversion of argument passed to inotify_init1. inotify_init1 flags can be IN_NONBLOCK and IN_CLOEXEC which rely on O_NONBLOCK and O_CLOEXEC and those can have different values on different platforms.

2017-02-14target/openrisc: Optimize for r0 being zeroRichard Henderson3-23/+66
The HW does not special-case r0, but the ABI specifies that r0 should contain 0. If we expose this fact to the optimizer, we can simplify a lot of the generated code. We must of course verify that r0==0, but that is trivial to do with a TB flag. Signed-off-by: Richard Henderson <rth@twiddle.net>
