2014-02-09block: Don't call ROUND_UP with negative valuesKevin Wolf1-2/+2
The behaviour of the ROUND_UP macro with negative numbers isn't obvious. It happens to do the right thing in this please, but better avoid it.

This adds assertions that the request that we actually end up passing to the block driver (which includes RMW data and has therefore potentially been rounded to alignment boundaries) is fully covered by the overlap_{offset,size} fields of the associated BdrvTrackedRequest.

2014-02-09raw: Fix BlockLimits passthroughKevin Wolf1-1/+7
raw copies over the BlockLimits of bs->file during bdrv_open(). However, since commit d34682cd it is immediately overwritten during bdrv_refresh_limits(). This caused all fields except for opt_transfer_length and opt_mem_alignment (which happen to be correctly inherited in generic code) to be zeroed. Move the BlockLimit assignment to a .bdrv_refresh_limits() callback to make it work again for all fields.

2014-02-09qcow2: check for NULL l2metaHu Tao1-15/+16
In the case of a metadata preallocation with a large cluster size, qcow2_alloc_cluster_offset() can allocate nothing and returns a NULL l2meta. This patch checks for it and link2 l2 with only valid l2meta. Replace 9 and 512 with BDRV_SECTOR_BITS, BDRV_SECTOR_SIZE respectively while at the function.

2014-02-09qcow2: fix offset overflow in qcow2_alloc_clusters_at()Hu Tao1-1/+7
When cluster size is big enough it can lead to an offset overflow in qcow2_alloc_clusters_at(). This patch fixes it. The allocation is stopped each time at L2 table boundary (see handle_alloc()), so the possible maximum bytes could be 2^(cluster_bits - 3 + cluster_bits) cluster_bits - 3 is used to compute the number of entry by L2 and the additional cluster_bits is to take into account each clusters referenced by the L2 entries. so int is safe for cluster_bits<=17, unsafe otherwise.

2014-02-09qcow2: remove n_start and n_end of qcow2_alloc_cluster_offset()Hu Tao4-16/+15
n_start can be actually calculated from offset. The number of sectors to be allocated(n_end - n_start) can be passed in in num. By removing n_start and n_end, we can save two parameters. The side effect is there is a bug in qcow2.c:preallocate() that passes incorrect n_start to qcow2_alloc_cluster_offset() is fixed. The bug can be triggerred by a larger cluster size than the default value(65536), for example: ./qemu-img create -f qcow2 \ -o 'cluster_size=131072,preallocation=metadata' file.img 4G Signed-off-by: Hu Tao <hutao@cn.fujitsu.com> Reviewed-by: Max Reitz <mreitz@redhat.com> Reviewed-by: Benoit Canet <benoit@irqsave.net> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2014-02-09block: add native support for NFSPeter Lieven5-0/+472
This patch adds native support for accessing images on NFS shares without the requirement to actually mount the entire NFS share on the host. NFS Images can simply be specified by an url of the form: nfs://<host>/<export>/<filename>[?param=value[&param2=value2[&...]]] For example: qemu-img create -f qcow2 nfs://10.0.0.1/qemu-images/test.qcow2 You need LibNFS from Ronnie Sahlberg available at: git://github.com/sahlberg/libnfs.git for this to work. During configure it is automatically probed for libnfs and support is enabled on-the-fly. You can forbid or enforce libnfs support with --disable-libnfs or --enable-libnfs respectively. Due to NFS restrictions you might need to execute your binaries as root, allow them to open priviledged ports (<1024) or specify insecure option on the NFS server. For additional information on ROOT vs. non-ROOT operation and URL format + parameters see: https://raw.github.com/sahlberg/libnfs/master/README Supported by qemu are the uid, gid and tcp-syncnt URL parameters.
