2013-08-06vmdk: check l1 size before opening imageFam Zheng
L1 table size is calculated from capacity, granularity and l2 table size. If capacity is too big or later two are too small, the L1 table will be too big to allocate in memory. Limit it to a reasonable range. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2013-08-06vmdk: check l2 table size when openingFam Zheng
header.num_gtes_per_gte determines size for L2 table. Check for too big value before using it. Limit to 512M entries (2GB per one L2 table). Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2013-08-06vmdk: check granularity field in openingFam Zheng
Granularity is used to calculate the cluster size and allocate r/w buffer. Check the value from image before using it, so we don't abort() for unbounded memory allocation. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2013-08-02block: Disable driver-specific options for 1.6Kevin Wolf
We don't want to commit to the API yet before everything is worked out. Like already for 1.5, disable it again for the 1.6 release. This commit is meant to be reverted after the 1.6 release. The disabling of the driver-specific options is achieved by applying the old checks while parsing the command line.

2013-07-29qapi.py: Restructure lexer and parserMarkus Armbruster
The parser has a rather unorthodox structure: Until EOF: Read a section: Generator function get_expr() yields one section after the other, as a string. An unindented, non-empty line that isn't a comment starts a new section. Lexing: Split section into a list of tokens (strings), with help of generator function tokenize(). Parsing: Parse the first expression from the list of tokens, with parse(), throw away any remaining tokens. In parse_schema(): record value of an enum, union or struct key (if any) in the appropriate global table, append expression to the list of expressions. Return list of expressions. Known issues: (1) Indentation is significant, unlike in real JSON. (2) Neither lexer nor parser have any idea of source positions. Error reporting is hard, let's go shopping. (3) The one error we bother to detect, we "report" via raise. (4) The lexer silently ignores invalid characters. (5) If everything in a section gets ignored, the parser crashes. (6) The lexer treats a string containing a structural character exactly like the structural character. (7) Tokens trailing the first expression in a section are silently ignored. (8) The parser accepts any token in place of a colon. (9) The parser treats comma as optional. (10) parse() crashes on unexpected EOF. (11) parse_schema() crashes when a section's expression isn't a JSON object. Replace this piece of original art by a thoroughly unoriginal design. Takes care of (1), (2), (5), (6) and (7), and lays the groundwork for addressing the others. Generated source files remain unchanged.

2013-07-15blockdev: add sync mode to drive-backup QMP commandStefan Hajnoczi
The drive-backup command is similar to the drive-mirror command, except no guest data written after the command executes gets copied. Add a sync mode argument which determines whether the entire disk is copied, just allocated clusters, or only clusters being written to by the guest. Currently only sync mode 'full' is supported - it copies the entire disk. For read-only point-in-time snapshots we may only need sync mode 'none' since the target can be a qcow2 file using the guest's disk as its backing file (no need to copy the entire disk). Finally, sync mode 'top' is useful if we wish to preserve the backing chain. Note that this patch just adds the sync mode argument to drive-backup. It does not implement sync modes 'top' or 'none'. This patch is necessary so we can add a drive-backup HMP command that behaves like the existing drive-mirror HMP command and takes a sync mode.
