| | | | | | | | | | Most drivers need to set length and offset as well, so may as well fold those three lines into one.

| | | | | | | | | | | | | | | | | | | | | | Commits 58b053e4ce9d2fc3023645c1b96e537c72aa8d9a ("Update arch/ to use sg helpers") 45711f1af6eff1a6d010703b4862e0d2b9afd056 ("[SG] Update drivers to use sg helpers") fa05f1286be25a8ce915c5dd492aea61126b3f33 ("Update net/ to use sg helpers") converted many files to use the scatter gather helpers without ensuring that the necessary headerfile <linux/scatterlist> is included. This happened to work for ia64, powerpc, sparc64 and x86 because they happened to drag in that file via their <asm/dma-mapping.h>. On most of the others this probably broke. Instead of increasing the header file spider web I choose to include <linux/scatterlist.h> directly into the affectes files.

* Remove old lguest bus and drivers.Rusty Russell2007-10-232-422/+0

* Block driver using virtio.Rusty Russell2007-10-233-0/+315
| | | | | | | | | | | | | | | | | | | | The block driver uses scatter-gather lists with sg[0] being the request information (struct virtio_blk_outhdr) with the type, sector and inbuf id. The next N sg entries are the bio itself, then the last sg is the status byte. Whether the N entries are in or out depends on whether it's a read or a write. We accept the normal (SCSI) ioctls: they get handed through to the other side which can then handle it or reply that it's unsupported. It's not clear that this actually works in general, since I don't know if blk_pc_request() requests have an accurate rq_data_dir(). Although we try to reply -ENOTTY on unsupported commands, ioctl(fd, CDROMEJECT) returns success to userspace. This needs a separate patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch disables DMA refetch in the PCI bridge. We have disabled DMA prefetch for quite some time. Testing with XEN revealed another ASIC bug. If dom0 resides on a P600 the board can can an MCA bi accessing invalid memory addresses. Apparently, we need to disable both prefetch and refetch. My understanding is a refetch operation should not occur but it is a valid thing to do if prefetched data is no longer available for whatever reason. Please consider this patch for inclusion.

* | floppy: remove register keyword use from floppy driverJesper Juhl2007-10-171-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | The floppy drive is slow. These days I see absolutely no good reason why the floppy driver should try to gain a tiny bit of speed by telling gcc to optimize access to some variables via the register keyword. Better to just leave gcc free to do whatever optimizations it deduces to be sane and not hamper it by telling it that some variables in the floppy driver are special and need to be fast (they don't).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a problem with the way cciss was filling out the "errors" field of the request structure upon completion of requests. Previously, it just put a 1 or a 0 in there and used the negation of this as the uptodate parameter to one of the functions in the block layer, being a block device. For the SG_IO ioctl, this was not sufficient, and we noticed that, for example, sg_turs from sg3_utils did not correctly detect problems due to cciss having set rq->errors incorrectly.

* | NBD: allow hung network I/O to be cancelledPaul Clements2007-10-171-31/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow NBD I/O to be cancelled when a network outage occurs. Previously, I/O would just hang, and if enough I/O was hung in nbd, the system (at least user-level) would completely hang until a TCP timeout (default, 15 minutes) occurred. The patch introduces a new ioctl NBD_SET_TIMEOUT that allows a transmit timeout value (in seconds) to be specified. Any network send that exceeds the timeout will be cancelled and the nbd connection will be shut down. I've tested with various timeout values and 6 seconds seems to be a good choice for the timeout. If the NBD_SET_TIMEOUT ioctl is not called, you get the old (I/O hang) behavior.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Partial write can be easily supported by LO_CRYPT_NONE mode, but it is not easy in LO_CRYPT_CRYPTOAPI case, because of its block nature. I don't know who still used cryptoapi, but theoretically it is possible. So let's leave things as they are. Loop device doesn't support partial write before Nick's "write_begin/write_end" patch set, and let's it behave the same way after.

| * | [NET]: Make the device list and device lookups per namespace.Eric W. Biederman2007-10-101-1/+2

This patch makes dev_base_head a network namespace variable, and then it picks up a few associated variables. The functions: dev_getbyhwaddr dev_getfirsthwbytype dev_get_by_flags dev_get_by_name __dev_get_by_name dev_get_by_index __dev_get_by_index dev_ioctl dev_ethtool dev_load wireless_process_ioctl were modified to take a network namespace argument, and deal with it. vlan_ioctl_set and brioctl_set were modified so their hooks will receive a network namespace argument. So basically anthing in the core of the network stack that was affected to by the change of dev_base was modified to handle multiple network namespaces. The rest of the network stack was simply modified to explicitly use &init_net the initial network namespace. This can be fixed when those components of the network stack are modified to handle multiple network namespaces. For now the ifindex generator is left global. Fundametally ifindex numbers are per namespace, or else we will have corner case problems with migration when we get that far. At the same time there are assumptions in the network stack that the ifindex of a network device won't change. Making the ifindex number global seems a good compromise until the network stack can cope with ifindex changes when you change namespaces, and the like. Signed-off-by: Eric W.

This should ensure that the various network stacks do not receive packets in a anything but the initial network namespace until the code has been converted and is ready for them.
