2008-05-02USB: usbtest displays diagnostics againDavid Brownell
Minor cleanup to the "usbtest" driver, mostly to resolve a regression: all the important diagnostics were at KERN_DEBUG, so that when the "#define DEBUG" was removed from the top of that file it stopped providing diagnostics. Fix by using KERN_ERROR. Also: - Stop using the legacy dbg() calls - Simplify the internal debug macros - Correct some test descriptions: * Test #10 subcase 7 should *always* stall * Test #10 subcase 8 *may* stall - Diagnostic about control queue test failures is more informative - Fix some whitespace "bugs" And add a warning about the rude interaction between usbfs ioctl() and khubd during device disconnect ... don't unplug a device under test, that will wedge.

I hoped to continue to ignore this problem or use libusual, but these days it's simpler to work around than to deal with it.

2008-05-02ub: Fix timeoutsPete Zaitcev
The wodim says: "close track/session scsi sendcmd: cmd timeout after 5.000 (480) s" This happened because we ignored the supplied timeout and used 5s. It's not completely correct to apply a timeout meant for the complete command to any single URB, but we don't have many URBs per command, so this is simple and works.

2008-05-02[SCSI] add support for variable length extended commandsBoaz Harrosh
Add support for variable-length, extended, and vendor specific CDBs to scsi-ml. It is now possible for initiators and ULD's to issue these types of commands. LLDs need not change much. All they need is to raise the .max_cmd_len to the longest command they support (see iscsi patch). - clean-up some code paths that did not expect commands to be larger than 16, and change cmd_len members' type to short as char is not enough.

2008-05-02[SCSI] Let scsi_cmnd->cmnd use request->cmd bufferBoaz Harrosh
- struct scsi_cmnd had a 16 bytes command buffer of its own. This is an unnecessary duplication and copy of request's cmd. It is probably left overs from the time that scsi_cmnd could function without a request attached. So clean that up. - Once above is done, few places, apart from scsi-ml, needed adjustments due to changing the data type of scsi_cmnd->cmnd. - Lots of drivers still use MAX_COMMAND_SIZE. So I have left that #define but equate it to BLK_MAX_CDB. The way I see it and is reflected in the patch below is. MAX_COMMAND_SIZE - means: The longest fixed-length (*) SCSI CDB as per the SCSI standard and is not related to the implementation. BLK_MAX_CDB. - The allocated space at the request level - I have audit all ISA drivers and made sure none use ->cmnd in a DMA Operation. Same audit was done by Andi Kleen. (*)fixed-length here means commands that their size can be determined by their opcode and the CDB does not carry a length specifier, (unlike the VARIABLE_LENGTH_CMD(0x7f) command). This is actually not exactly true and the SCSI standard also defines extended commands and vendor specific commands that can be bigger than 16 bytes. The kernel will support these using the same infrastructure used for VARLEN CDB's. So in effect MAX_COMMAND_SIZE means the maximum size command scsi-ml supports without specifying a cmd_len by ULD's Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

2008-05-02virtio: explicit advertisement of driver featuresRusty Russell
A recent proposed feature addition to the virtio block driver revealed some flaws in the API: in particular, we assume that feature negotiation is complete once a driver's probe function returns. There is nothing in the API to require this, however, and even I didn't notice when it was violated. So instead, we require the driver to specify what features it supports in a table, we can then move the feature negotiation into the virtio core. The intersection of device and driver features are presented in a new 'features' bitmap in the struct virtio_device. Note that this highlights the difference between Linux unsigned-long bitmaps where each unsigned long is in native endian, and a straight-forward little-endian array of bytes. Drivers can still remove feature bits in their probe routine if they really have to. API changes: - dev->config->feature() no longer gets and acks a feature. - drivers should advertise their features in the 'feature_table' field - use virtio_has_feature() for extra sanity when checking feature bits Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-05-02virtio: change config to guest endian.Rusty Russell
A recent proposed feature addition to the virtio block driver revealed some flaws in the API, in particular how easy it is to break big endian machines. The virtio config space was originally chosen to be little-endian, because we thought the config might be part of the PCI config space for virtio_pci. It's actually a separate mmio region, so that argument holds little water; as only x86 is currently using the virtio mechanism, we can change this (but must do so now, before the impending s390 merge). API changes: - __virtio_config_val() just becomes a striaght vdev->config_get() call. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-05-02virtio: finer-grained features for virtio_netRusty Russell
So, we previously had a 'VIRTIO_NET_F_GSO' bit which meant that 'the host can handle csum offload, and any TSO (v4&v6 incl ECN) or UFO packets you might want to send. I thought this was good enough for Linux, but it actually isn't, since we don't do UFO in software. So, add separate feature bits for what the host can handle. Add equivalent ones for the guest to say what it can handle, because LRO is coming too (thanks Herbert!). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
