* qemu-nbd: Fix invalid usage of the first argument of errxRyota Ozaki2010-03-271-17/+17
| | | | | | | | | errx takes the exit status of a process as the first argument. Passing errno to it is wrong. Instead the patch lets errx take EXIT_FAILURE. Signed-off-by: Ryota Ozaki <ozaki.ryota@gmail.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
* qemu-nbd: Fix return value handling of bdrv_openRyota Ozaki2010-03-271-1/+1
| | | | | | | | bdrv_open may return -errno so we have to check if the return value is '< 0', not '== -1'. Signed-off-by: Ryota Ozaki <ozaki.ryota@gmail.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

* win32: pair qemu_memalign() with qemu_vfree()Herve Poussineau2010-01-261-1/+1
| | | | | | | | | | Win32 suffers from a very big memory leak when dealing with SCSI devices. Each read/write request allocates memory with qemu_memalign (ie VirtualAlloc) but frees it with qemu_free (ie free). Pair all qemu_memalign() calls with qemu_vfree() to prevent such leaks.

* Clean-up a little bit the RW related bits of BDRV_O_FLAGS. BDRV_O_RDONLY ↵Naphtali Sprei2010-01-201-1/+1
| | | | | | | | | | gone (and so is BDRV_O_ACCESS). Default value for bdrv_flags (0/zero) is READ-ONLY. Need to explicitly request READ-WRITE. Instead of using the field 'readonly' of the BlockDriverState struct for passing the request, pass the request in the flags parameter to the function.

* Expand cache= option and use write-through caching by defaultaliguori2008-10-141-1/+1
| | | | | | | | | | | | | | | | | | This patch changes the cache= option to accept none, writeback, or writethough to control the host page cache behavior. By default, writethrough caching is now used which internally is implemented by using O_DSYNC to open the disk images. When using -snapshot, writeback is used by default since data integrity it not at all an issue. cache=none has the same behavior as cache=off previously. The later syntax is still supported by now deprecated. I also cleaned up the O_DIRECT implementation to avoid many of the #ifdefs.
