* do not call vhost_net_cleanup() on running net from char user eventDan Streetman2019-05-211-1/+0Star
| | | | | | | | | | | | | | | | | | | | Buglink: https://launchpad.net/bugs/1823458 Currently, a user CHR_EVENT_CLOSED event will cause net_vhost_user_event() to call vhost_user_cleanup(), which calls vhost_net_cleanup() for all its queues. However, vhost_net_cleanup() must never be called like this for fully-initialized nets; when other code later calls vhost_net_stop() - such as from virtio_net_vhost_status() - it will try to access the already-cleaned-up fields and fail with assertion errors or segfaults. The vhost_net_cleanup() will eventually be called from qemu_cleanup_net_client().

| | | | | | | | | | | | | | | Because event_unhandled_count may be accessed concurrently, it needs to be protected by taking the lock. However the assert is outside the lock, probably causing it to read garbage and aborting Qemu erroneously. The Bug only happens when running Qemu in COLO mode.

* net/socket: learn to talk with a unix dgram socketMarc-André Lureau2019-03-291-4/+21
| | | | | | | | | | | | | | | | | | | | | | | | | -net socket has a fd argument, and may be passed pre-opened sockets. TCP sockets use framing. UDP sockets have datagram boundaries. When given a unix dgram socket, it will be able to read from it, but will attempt to send on the dgram_dst, which is unset. The other end will not receive the data. Let's teach -net socket to recognize a UNIX DGRAM socket, and use the regular send() command (without dgram_dst). This makes running slirp out-of-process possible that way (python pseudo-code): a, b = socket.socketpair(socket.AF_UNIX, socket.SOCK_DGRAM) subprocess.Popen('qemu -net socket,fd=%d -net user' % a.fileno(), shell=True) subprocess.Popen('qemu ... -net nic -net socket,fd=%d' % b.fileno(), shell=True) Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>

Introduce slirp_state_{load,save,version}() functions to move the state saving handling to libslirp side. So far, the bitstream compatibility should remain equal with current QEMU, as this is effectively using the same code, with the same format etc. When libslirp is made standalone, we will need some mechanism to ensure bitstream compatibility regardless of the libslirp version installed.

| | | | | | | | | | | | | | | | Changes: - Save CPU cycles by computing the return value while scanning the input iovec, rather than calling iov_size() at the end. - Remove check for s->tx != NULL, because it cannot happen. - Cache ring->tail in a local variable and use it to check for space in the TX ring. The use of nm_ring_empty() was invalid, because nobody is updating ring->cur and ring->head at that point. - In case we run out of netmap slots in the middle of a packet, move the wake-up point by advancing ring->cur, but do not expose the incomplete packet (i.e., by updating also ring->head).

| | | | | | | | | | | | | | | | | | | | | hw/net/vhost_net.c needs functions that are declared in net/vhost-user.c: the vhost-user code is always compiled into QEMU, only the constructor net_init_vhost_user is unreachable.

First, add a minimal version of net/vhost-user.c, with no functionality and no dependency on vhost code. Second, #ifdef out the calls back to net/vhost-user.c from hw/net/vhost_net.c.

Change them to spaces so that we don't confuse people. disas, standard-headers, linux-headers and libdecnumber are imported from other projects and probably should be exempted from the check. Outside those, after this patch the following files still contain both 8-space and TAB sequences at the beginning of the line. Many of them have a majority of TABs, or were initially committed with all tabs. bsd-user/i386/target_syscall.h bsd-user/x86_64/target_syscall.h crypto/aes.c hw/audio/fmopl.c hw/audio/fmopl.h hw/block/tc58128.c hw/display/cirrus_vga.c hw/display/xenfb.c hw/dma/etraxfs_dma.c hw/intc/sh_intc.c hw/misc/mst_fpga.c hw/net/pcnet.c hw/sh4/sh7750.c hw/timer/m48t59.c hw/timer/sh_timer.c include/crypto/aes.h include/disas/bfd.h include/hw/sh4/sh.h libdecnumber/decNumber.c linux-headers/asm-generic/unistd.h linux-headers/linux/kvm.h linux-user/alpha/target_syscall.h linux-user/arm/nwfpe/double_cpdo.c linux-user/arm/nwfpe/fpa11_cpdt.c linux-user/arm/nwfpe/fpa11_cprt.c linux-user/arm/nwfpe/fpa11.h linux-user/flat.h linux-user/flatload.c linux-user/i386/target_syscall.h linux-user/ppc/target_syscall.h linux-user/sparc/target_syscall.h linux-user/syscall.c linux-user/syscall_defs.h linux-user/x86_64/target_syscall.h slirp/cksum.c slirp/if.c slirp/ip.h slirp/ip_icmp.c slirp/ip_icmp.h slirp/ip_input.c slirp/ip_output.c slirp/mbuf.c slirp/misc.c slirp/sbuf.c slirp/socket.c slirp/socket.h slirp/tcp_input.c slirp/tcpip.h slirp/tcp_output.c slirp/tcp_subr.c slirp/tcp_timer.c slirp/tftp.c slirp/udp.c slirp/udp.h target/cris/cpu.h target/cris/mmu.c target/cris/op_helper.c target/sh4/helper.c target/sh4/op_helper.c target/sh4/translate.c tcg/sparc/tcg-target.inc.c tests/tcg/cris/check_addo.c tests/tcg/cris/check_moveq.c tests/tcg/cris/check_swap.c tests/tcg/multiarch/test-mmap.c ui/vnc-enc-hextile-template.h ui/vnc-enc-zywrle.h util/envlist.c util/readline.c The following have only TABs: bsd-user/i386/target_signal.h bsd-user/sparc64/target_signal.h bsd-user/sparc64/target_syscall.h bsd-user/sparc/target_signal.h bsd-user/sparc/target_syscall.h bsd-user/x86_64/target_signal.h crypto/desrfb.c hw/audio/intel-hda-defs.h hw/core/uboot_image.h hw/sh4/sh7750_regnames.c hw/sh4/sh7750_regs.h include/hw/cris/etraxfs_dma.h linux-user/alpha/termbits.h linux-user/arm/nwfpe/fpopcode.h linux-user/arm/nwfpe/fpsr.h linux-user/arm/syscall_nr.h linux-user/arm/target_signal.h linux-user/cris/target_signal.h linux-user/i386/target_signal.h linux-user/linux_loop.h linux-user/m68k/target_signal.h linux-user/microblaze/target_signal.h linux-user/mips64/target_signal.h linux-user/mips/target_signal.h linux-user/mips/target_syscall.h linux-user/mips/termbits.h linux-user/ppc/target_signal.h linux-user/sh4/target_signal.h linux-user/sh4/termbits.h linux-user/sparc64/target_syscall.h linux-user/sparc/target_signal.h linux-user/x86_64/target_signal.h linux-user/x86_64/termbits.h pc-bios/optionrom/optionrom.h slirp/mbuf.h slirp/misc.h slirp/sbuf.h slirp/tcp.h slirp/tcp_timer.h slirp/tcp_var.h target/i386/svm.h target/sparc/asi.h target/xtensa/core-dc232b/xtensa-modules.inc.c target/xtensa/core-dc233c/xtensa-modules.inc.c target/xtensa/core-de212/core-isa.h target/xtensa/core-de212/xtensa-modules.inc.c target/xtensa/core-fsf/xtensa-modules.inc.c target/xtensa/core-sample_controller/core-isa.h target/xtensa/core-sample_controller/xtensa-modules.inc.c target/xtensa/core-test_kc705_be/core-isa.h target/xtensa/core-test_kc705_be/xtensa-modules.inc.c tests/tcg/cris/check_abs.c tests/tcg/cris/check_addc.c tests/tcg/cris/check_addcm.c tests/tcg/cris/check_addoq.c tests/tcg/cris/check_bound.c tests/tcg/cris/check_ftag.c tests/tcg/cris/check_int64.c tests/tcg/cris/check_lz.c tests/tcg/cris/check_openpf5.c tests/tcg/cris/check_sigalrm.c tests/tcg/cris/crisutils.h tests/tcg/cris/sys.c tests/tcg/i386/test-i386-ssse3.c ui/vgafont.h Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Message-Id: <20181213223737.11793-3-pbonzini@redhat.com> Reviewed-by: Aleksandar Markovic <amarkovic@wavecomp.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Wainer dos Santos Moschetta <wainersm@redhat.com> Acked-by: Richard Henderson <richard.henderson@linaro.org> Acked-by: Eric Blake <eblake@redhat.com> Acked-by: David Gibson <david@gibson.dropbear.id.au> Reviewed-by: Stefan Markovic <smarkovic@wavecomp.com> Reviewed-by: Michael S.

* qemu/queue.h: simplify reverse access to QTAILQPaolo Bonzini2019-01-112-2/+2

* qemu/queue.h: leave head structs anonymous unless necessaryPaolo Bonzini2019-01-112-2/+2
| | | | | | | | | | | | Most list head structs need not be given a name. In most cases the name is given just in case one is going to use QTAILQ_LAST, QTAILQ_PREV or reverse iteration, but this does not apply to lists of other kinds, and even for QTAILQ in practice this is only rarely needed. In addition, we will soon reimplement those macros completely so that they do not need a name for the head struct. So clean up everything, not giving a name except in the rare case where it is necessary. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
