2012-08-01net: add the support for -netdev socket, listenZhi Yong Wu
The -net socket,listen option does not work with the newer -netdev syntax: http://lists.gnu.org/archive/html/qemu-devel/2011-11/msg01508.html This patch makes it work now. For the case where one vlan has multiple listenning sockets, the patch will also provide the support. Supported syntax: 1.) -net socket,listen=127.0.0.1:1234,vlan=0 2.) -net socket,listen=127.0.0.1:1234,vlan=0 -net socket,listen=127.0.0.1:1235,vlan=0 3.) -netdev socket,listen=127.0.0.1:1234,id=socket0 Drop the NetSocketListenState struct and add a listen_fd field to NetSocketState. When a -netdev socket,listen= instance is created there will be a NetSocketState with fd=-1 and a valid listen_fd. The net_socket_accept() handler waits for listen_fd to become readable and then accepts the connection. When this state transition happens, we no longer monitor listen_fd for incoming connections...until the client disconnects again.

2012-07-23convert net_client_init() to OptsVisitorLaszlo Ersek
The net_client_init() prototype is kept intact. Based on "is_netdev", the QemuOpts-rooted QemuOpt-list is parsed as a Netdev or a NetLegacy. The original meat of net_client_init() is moved to and simplified in net_client_init1(): Fields not common between -net and -netdev are clearly separated. Getting the name for the init functions is cleaner: Netdev::id is mandatory, and all init functions handle a NULL NetLegacy::name. NetLegacy::vlan explicitly depends on -net (see below). Verifying the "type=" option for -netdev can be turned into a switch. Format validation with qemu_opts_validate() can be removed because the visitor covers it. Relatedly, the "net_client_types" array is reduced to an array of init functions that can be directly indexed by opts->kind. (Help text is available in the schema JSON.) The outermost negation in the condition around qemu_find_vlan() was flattened, because it expresses the dependent code's requirements more clearly. VLAN lookup is avoided if there's no init function to pass the VLAN to. Whenever the value of type=... is needed, we substitute NetClientOptionsKind_lookup[kind]. The individual init functions are not converted yet, thus the original QemuOpts instance is passed transparently. v1->v2: - NetLegacy::name is optional. Tracked it through all init functions: they all handle a NULL name. Updated commit message accordingly. v2->v3: - NetLegacy::id is allowed and takes precedence over NetLegacy::name.

2012-06-09do not include <libutil.h> needlessly or if it doesn't existMichael Tokarev
<libutil.h> and <util.h> on *BSD (some have one, some another) were #included just for openpty() declaration. The only file where this function is actually used is qemu-char.c. In vl.c and net/tap-bsd.c, none of functions declared in libutil.h (login logout logwtmp timdomain openpty forkpty uu_lock realhostname fparseln and a few others depending on version) are used. Initially the code which is currently in qemu-char.c was in vl.c, it has been removed into separate file in commit 0e82f34d077dc2542 Fri Oct 31 18:44:40 2008, but the #includes were left in vl.c. So with vl.c, we just remove includes - libutil.h, util.h and pty.h (which declares only openpty() and forkpty()) from there. The code in net/tap-bsd.c, which come from net/tap.c, had this commit 5281d757efa6e40d74ce124be048b08d43887555 Author: Mark McLoughlin <markmc@redhat.com> Date: Thu Oct 22 17:49:07 2009 +0100 net: split all the tap code out into net/tap.c Note this commit not only moved stuff out of net.c to net/tap.c, but also rewrote large portions of the tap code, and added these completely unnecessary #includes -- as usual, I question why such a misleading commit messages are allowed. Again, no functions defined in libutil.h or util.h on *BSD are used by neither net/tap.c nor net/tap-bsd.c. Removing them. And finally, the only real user for these #includes, qemu-char.c, which actually uses openpty(). There, the #ifdef logic is wrong. A GLIBC-based system has <pty.h>, even if it is a variant of *BSD. So __GLIBC__ should be checked first, and instead of trying to include <libutil.h> or <util.h>, we include <pty.h>. If it is not GLIBC-based, we check for variations between <*util.h> as before. This patch fixes build of qemu 1.1 on Debian/kFreebsd (well, one of the two problems): it is a distribution with a FreeBSD kernel, so it #defines at least __FreeBSD_kernel__, but since it is based on GLIBC, it has <pty.h>, but current version does not have neither <util.h> nor <libutil.h>, which the code tries to include 3 times but uses only once.

2012-05-01Declare state directory in smb.confNikolaus Rath
The smb.conf generated by the userspace networking does not include a state directory directive. Samba therefore falls back to the default value. Since the user generally does not have write access to this path, smbd immediately crashes. The "state directory" option was added in Samba 3.4.0 (commit http://gitweb.samba.org/?p=samba.git;a=commit;h=7b02e05eb64f3ffd7aa1cf027d10a7343c0da757). This patch adds the missing option.

2012-05-01slirp: don't use "smb ports = 0" optionNikolaus Rath
The "smb ports = 0" option causes recent samba versions to crash. It was introduced in commit 157777ef3e with log message "Samba 3 support". However, a value of 0 has never been officially supported by smb and is also not necessary: if stdin is a socket, smb does not try to listen on any ports and uses just stdin. This is necessary to support inetd based operation (otherwise smbd would always fail when called from inetd, because inetd already listens on the SMB port). Since samba has supported inetd operation since pre-3.x, it should be safe to rely on this feature. I have tested it with Samba 3.6.4 -- communication works fine, and smbd is not listening on any ports. I suspect the "smb ports = 0" hack may have been introduced when someone tested the qemu generated samba config from the command line with "smbd -i" and found it to fail (because then stdin isn't a socket).

2012-02-01Add support for net bridgeCorey Bryant
The most common use of -net tap is to connect a tap device to a bridge. This requires the use of a script and running qemu as root in order to allocate a tap device to pass to the script. This model is great for portability and flexibility but it's incredibly difficult to eliminate the need to run qemu as root. The only really viable mechanism is to use tunctl to create a tap device, attach it to a bridge as root, and then hand that tap device to qemu. The problem with this mechanism is that it requires administrator intervention whenever a user wants to create a guest. By essentially writing a helper that implements the most common qemu-ifup script that can be safely given cap_net_admin, we can dramatically simplify things for non-privileged users. We still support existing -net tap options as a mechanism for advanced users and backwards compatibility. Currently, this is very Linux centric but there's really no reason why it couldn't be extended for other Unixes. A typical invocation would be similar to one of the following: qemu linux.img -net bridge -net nic,model=virtio qemu linux.img -net tap,helper="/usr/local/libexec/qemu-bridge-helper" -net nic,model=virtio qemu linux.img -netdev bridge,id=hn0 -device virtio-net-pci,netdev=hn0,id=nic1 qemu linux.img -netdev tap,helper="/usr/local/libexec/qemu-bridge-helper",id=hn0 -device virtio-net-pci,netdev=hn0,id=nic1 The default bridge that we attach to is br0. The thinking is that a distro could preconfigure such an interface to allow out-of-the-box bridged networking. Alternatively, if a user wants to use a different bridge, a typical invocation would be simliar to one of the following: qemu linux.img -net bridge,br=qemubr0 -net nic,model=virtio qemu linux.img -net tap,helper="/usr/local/libexec/qemu-bridge-helper --br=qemubr0" -net nic,model=virtio qemu linux.img -netdev bridge,br=qemubr0,id=hn0 -device virtio-net-pci,netdev=hn0,id=nic1 qemu linux.img -netdev tap,helper="/usr/local/libexec/qemu-bridge-helper --br=qemubr0",id=hn0 -device virtio-net-pci,netdev=hn0,id=nic1 Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Richa Marwaha <rmarwah@linux.vnet.ibm.com> Signed-off-by: Corey Bryant <coreyb@linux.vnet.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-12-15network scripts: don't block SIGCHLD before forkingMichael Roth
This patch fixes a bug where child processes of launch_script() can misbehave due to SIGCHLD being blocked. In the case of `sudo`, this causes a permanent hang. Previously a SIGCHLD handler was added to reap fork_exec()'d zombie processes by calling waitpid(-1, ...). This required other fork()/waitpid() callers to temporarilly block SIGCHILD to avoid having the final wait status being intercepted by the SIGCHLD handler: 7c3370d4fe3fa6cda8655f109e4659afc8ca4269 Since then, the qemu_add_child_watch() interface was added to allow registration of such processes and reap only from that specific set of PIDs: 4d54ec7898bd951007cb6122d5315584bd41d0c4 As a result, we can now avoid blocking SIGCHLD in launch_script(), so drop that behavior.
