2014-03-12slirp smb with modern win guests when samba is also running on hostMichael Tokarev1-1/+2
After numerous reports that -smb (or -netdev user,smb=foo) not working with modern windows (win7 and vista are reported as non-working), I started digging myself. And found that indeed it doesn't work, and why. The thing is that modern win tries to connect to port 445 (microsoft-ds) first, and if that fails, it falls back to old port 139 (netbios-ssn). slirp code in qemu only redirects port 139, it does not touch port 445. So the prob is that if samba is also running on the host, guest will try to communicate using port 445, and that will succed, but ofcourse guest will not talk with our samba but with samba running on the host. If samba is not running on the host, guest will fall back to port 139, and will reach the redirecting rule and qemu will spawn smbd correctly. The solution is to redirect both ports (139 and 445), and the fix is a one-liner, adding second call to slirp_add_exec() at the end of net/slirp.c:slirp_smb() function (provided below). But it looks like that is not a proper fix really, since in theory we should redirect both ports to the SAME, single samba instance, but I'm not sure this is possible with slirp. Well, even if two smbd processes will be run on the same config dir, it should not be a problem. The one-liner (not exactly 1 since it touches previous line too) is like this: Signed-off-By: Michael Tokarev <mjt@tls.msk.ru> Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2014-03-12qemu/slirp: Fix SMB security configuration on newer samba versionsMichael Buesch1-1/+2
The smb.conf automatically generated by qemu's -smb option fails on current samba, because smbd rejects the security=share option with the following warning: > WARNING: Ignoring invalid value 'share' for parameter 'security' Which makes it fall back to security=user without guest login. This results in being unable to login to the samba server from the guest OS. This fixes it by selecting 'user' explicitly and mapping unknown users to guest logins.

2013-04-04qemu-char: Call fe_claim / fe_release when not using qdev chr propertiesHans de Goede1-0/+1
chardev-frontends need to explictly check, increase and decrement the avail_connections "property" of the chardev when they are not using a qdev-chardev-property for the chardev. This fixes things like: qemu-kvm -chardev stdio,id=foo -device isa-serial,chardev=foo \ -mon chardev=foo Working, where they should fail. Most of the changes here are due to old hardware emulation code which is using serial_hds directly rather then a qdev-chardev-property.

2012-10-08net: consolidate NetClientState header files into onePaolo Bonzini1-1/+2
This patch doesn't seem much useful alone, I must admit. However, it makes sense as part of the upcoming directory reorganization, where I want to have include/net/tap.h as the net<->hw interface for tap. Then having both net/tap.h and include/net/tap.h does not work. "Fixed" by moving all the init functions to a single header file net/clients.h. The patch also adopts a uniform style for including net/*.h files from net/*.c, without the net/ path.

2012-07-23convert net_client_init() to OptsVisitorLaszlo Ersek1-1/+2
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.

2012-07-09slirp: Ensure smbd and shared directory exist when enable smbDunrong Huang1-0/+12
Users may pass the following parameters to qemu: $ qemu-kvm -net nic -net user,smb= ... $ qemu-kvm -net nic -net user,smb ... $ qemu-kvm -net nic -net user,smb=bad_directory ... In these cases, qemu started successfully while samba server failed to start. Users will confuse since samba server failed silently without any indication of what it did wrong. To avoid it, we check whether the shared directory exist and if users have permission to access this directory when QEMU's "built-in" SMB server is enabled.

2012-07-09slirp: add 'cmd:' target for guestfwdAlexander Graf1-17/+27
When using guestfwd=, Qemu only connects the virtual server's TCP port to a single chardev. This is useless in most cases, as we usually want to have more than a single connection from the guest to the outside world. This patch adds a new cmd: target to guestfwd= that allows for execution of a command on every TCP connection. This leverages the same code as the -smb parameter, just that here the command is user defined.

2012-05-01Declare state directory in smb.confNikolaus Rath1-0/+2
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 Rath1-1/+0
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).
