2011-06-08vmdk: fix endianness bugsAlexander Graf
The vmdk code is sloppy when handling the header descriptor during creation of an image. Fix all header accesses in the create path to either store native endianness or convert it when appropriate.

2011-06-08block: clarify the meaning of BDRV_O_NOCACHEChristoph Hellwig
Change BDRV_O_NOCACHE to only imply bypassing the host OS file cache, but no writeback semantics. All existing callers are changed to also specify BDRV_O_CACHE_WB to give them writeback semantics. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2011-06-08ide/core: Remove explicit setting of BM_STATUS_INTKevin Wolf
BM_STATUS_INT is automatically set during ide_set_irq(), there's no reason to set it manually in addition. There is even one case where the interrupt status bit was set, but no IRQ was raised. This is when the PRD table was reached but there is more data to transfer. The correct behaviour for this case is not to set BM_STATUS_INT. Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2011-06-08target-i386: Make x86 mfence and lfence illegal without SSE2Martin Simmons
While trying to use qemu -cpu pentium3 to test for incorrect uses of certain SSE2 instructions, I found that QEMU allowed the mfence and lfence instructions to be executed even though Pentium 3 doesn't support them. According to the processor specs (and experience on a real Pentium 3), these instructions are only available with SSE2, but QEMU is checking for SSE. The check for the related sfence instruction is correct (it works with SSE). This trival patch fixes the test.

2011-06-08slirp: fix guestfwd idAlexander Graf
When using -net user,guestfwd=... Qemu immediately complains about the id being in invalid format. This is because we pass in an id that contains a colon, while the id restrictions don't allow colons. This patch changes the colon into a dot, making guestfwd work again.

2011-06-07json-parser: add handling for NULL token listMichael Roth

2011-06-07json-streamer: add handling for JSON_ERROR token/stateMichael Roth
This allows a JSON_ERROR state to be passed to the streamer to force a flush of the current tokens and pass a NULL token list to the parser rather that have it churn on bad data. (Alternatively we could just not pass it to the parser at all, but it may be useful to push there errors up the stack. NULL token lists are not currently handled by the parser, the next patch will address that) Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-06-07json-lexer: make lexer error-recovery more deterministicMichael Roth
Currently when we reach an error state we effectively flush everything fed to the lexer, which can put us in a state where we keep feeding tokens into the parser at arbitrary offsets in the stream. This makes it difficult for the lexer/tokenizer/parser to get back in sync when bad input is made by the client. With these changes we emit an error state/token up to the tokenizer as soon as we reach an error state, and continue processing any data passed in rather than bailing out. The reset token will be used to reset the tokenizer and parser, such that they'll recover state as soon as the lexer begins generating valid token sequences again. We also map chr(192,193,245-255) to an error state here, since they are invalid UTF-8 characters. QMP guest proxy/agent will use chr(255) to force a flush/reset of previous input for reliable delivery of certain events, so also we document that thoroughly here.

2011-06-07json-lexer: fix flushing logic to not always go to error stateMichael Roth
Currently we flush the lexer by passing in a NULL character. This generally forces the lexer to go to the corresponding TERMINAL() state for whatever token type it is currently parsing, emits the token to the parser, then puts the lexer back into IN_START state. However, since a NULL character causes char_consumed to be 0, we always do a second pass after this, which puts us in the IN_ERROR state. Fix this behavior by adding a "flush" flag that tells the lexer not to do a more than 1 iteration.

2011-06-06spice: add SASL supportMarc-André Lureau
Turn on SASL support by appending "sasl" to the spice arguments, which requires that the client use SASL to authenticate with the spice. The exact choice of authentication method used is controlled from the system / user's SASL configuration file for the 'qemu' service. This is typically found in /etc/sasl2/qemu.conf. If running QEMU as an unprivileged user, an environment variable SASL_CONF_PATH can be used to make it search alternate locations for the service config. While some SASL auth methods can also provide data encryption (eg GSSAPI), it is recommended that SASL always be combined with the 'tls' and 'x509' settings to enable use of SSL and server certificates. This ensures a data encryption preventing compromise of authentication credentials. It requires support from spice 0.8.1.

2011-06-06spice-qemu-char: Fix flow control in client -> guest directionHans de Goede
In the old spice-vmc device we used to have: last_out = virtio_serial_write(&svc->port, p, MIN(len, VMC_MAX_HOST_WRITE)); if (last_out > 0) ... Now in the chardev backend we have: last_out = MIN(len, VMC_MAX_HOST_WRITE); qemu_chr_read(scd->chr, p, last_out); if (last_out > 0) { ... Which causes us to no longer detect if the virtio port is not ready to receive data from us. chardev actually has a mechanism to detect this, but it requires a separate call to qemu_chr_can_read, before calling qemu_chr_read (which return void). This patch uses qemu_chr_can_read to fix the flow control from client to guest. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
