* qemu-nbd: move client handling to nbd.cPaolo Bonzini2011-12-221-2/+3
| | | | | | | | | This patch sets up the fd handler in nbd.c instead of qemu-nbd.c. It introduces NBDClient, which wraps the arguments to nbd_trip in a single structure, so that we can add a notifier to it. This way, qemu-nbd can know about disconnections.

* qemu-nbd: introduce NBDExportPaolo Bonzini2011-12-221-3/+8
| | | | | | | Wrap the common parameters of nbd_trip and nbd_negotiate in a single opaque struct. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

* nbd: support feature negotiationPaolo Bonzini2011-09-191-3/+6
| | | | | | | | | nbd supports writing flags in bytes 24...27 of the header, and uses that for the read-only flag. Add support for it in qemu-nbd. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

* Fix include statements for qemu-common.hStefan Weil2011-09-091-1/+1
| | | | | | | | | | | | | | * qemu-common.h is not a system include file, so it should be included with "" instead of <>. Otherwise incremental builds might fail because only local include files are checked for changes. * linux-user/syscall.c included the file twice.

* Use new macro QEMU_PACKED for packed structuresStefan Weil2011-09-031-2/+2
| | | | | | | | | | | | | | | | | | | | | Most changes were made using these commands: git grep -la '__attribute__((packed))'|xargs perl -pi -e 's/__attribute__\(\(packed\)\)/QEMU_PACKED/' git grep -la '__attribute__ ((packed))'|xargs perl -pi -e 's/__attribute__ \(\(packed\)\)/QEMU_PACKED/' git grep -la '__attribute__((__packed__))'|xargs perl -pi -e 's/__attribute__\(\(__packed__\)\)/QEMU_PACKED/' git grep -la '__attribute__ ((__packed__))'|xargs perl -pi -e 's/__attribute__ \(\(__packed__\)\)/QEMU_PACKED/' git grep -la '__attribute((packed))'|xargs perl -pi -e 's/__attribute\(\(packed\)\)/QEMU_PACKED/' Whitespace in linux-user/syscall_defs.h was fixed manually to avoid warnings from scripts/checkpatch.pl. Manual changes were also applied to hw/pc.c. I did not fix indentation with tabs in block/vvfat.c. The patch will show 4 errors with scripts/checkpatch.pl.

* NBD: Use qemu_socket functions to open TCP and UNIX socketsNick Thomas2011-04-071-2/+7
| | | | | | | | | | | | | | | | | | This commit has the side-effect of making the qemu-nbd binary capable of binding to IPv6 addresses. ("-b ::1", for instance). block/nbd.c fails to parse IPv6 IP addresses correctly at this point, but will work over IPv6 when given a hostname. It still works over IPv4 as before. We move the qemu-sockets object from the 'common' to the 'block' list in the Makefile. The common list includes the block list, so this is effectively a no-op for the rest of the code. We also add 32-bit 'magic' attributes to nbd_(request|reply) to facilitate calculating maximum request/response sizes later.

| * nbd: Introduce NBD named exports.Laurent Vivier2010-08-301-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows to connect Qemu using NBD protocol to an nbd-server using named exports. For instance, if on the host "isoserver", in /etc/nbd-server/config, you have: [generic] [debian-500-ppc-netinst] exportname = /ISO/debian-500-powerpc-netinst.iso [Fedora-10-ppc-netinst] exportname = /ISO/Fedora-10-ppc-netinst.iso You can connect to it, using: qemu -cdrom nbd:isoserver:exportname=debian-500-ppc-netinst qemu -cdrom nbd:isoserver:exportname=Fedora-10-ppc-netinst NOTE: you need at least nbd-server 2.9.18 Signed-off-by: Laurent Vivier <laurent@vivier.eu> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
