2008-12-29drivers/net/usb: use USB API functions rather than constantsJulia Lawall
This set of patches introduces calls to the following set of functions: usb_endpoint_dir_in(epd) usb_endpoint_dir_out(epd) usb_endpoint_is_bulk_in(epd) usb_endpoint_is_bulk_out(epd) usb_endpoint_is_int_in(epd) usb_endpoint_is_int_out(epd) usb_endpoint_num(epd) usb_endpoint_type(epd) usb_endpoint_xfer_bulk(epd) usb_endpoint_xfer_control(epd) usb_endpoint_xfer_int(epd) usb_endpoint_xfer_isoc(epd) In some cases, introducing one of these functions is not possible, and it just replaces an explicit integer value by one of the following constants: USB_ENDPOINT_XFER_BULK USB_ENDPOINT_XFER_CONTROL USB_ENDPOINT_XFER_INT USB_ENDPOINT_XFER_ISOC In drivers/net/wireless/zd1211rw/zd_usb.c the code: (endpoint->bEndpointAddress & USB_TYPE_MASK) == USB_DIR_OUT is suspicious. If it is intended to use USB_ENDPOINT_DIR_MASK rather than USB_TYPE_MASK, then the whole conditional test could be converted to a call to usb_endpoint_is_bulk_in. An extract of the semantic patch that makes these changes is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r1@ struct usb_endpoint_descriptor *epd; @@ - ((epd->bmAttributes & \(USB_ENDPOINT_XFERTYPE_MASK\|3\)) == - \(USB_ENDPOINT_XFER_CONTROL\|0\)) + usb_endpoint_xfer_control(epd) @r5@ struct usb_endpoint_descriptor *epd; @@ - ((epd->bEndpointAddress & \(USB_ENDPOINT_DIR_MASK\|0x80\)) == - \(USB_DIR_IN\|0x80\)) + usb_endpoint_dir_in(epd) @inc@ @@ #include <linux/usb.h> @depends on !inc && (r1||r5)@ @@ + #include <linux/usb.h> #include <linux/usb/...> // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.

2008-12-29EtherExpress16: fix printing timed out statusRoel Kluin
in drivers/net/eexpress.c:558, function unstick_cu() while (!SCB_complete(rsst=scb_status(dev))) { ... if (...) printk(KERN_WARNING "%s: Reset timed out status %04x, retrying...\n", dev->name,rsst); } but this will become while (!((rsst = scb_status(dev) & 0x8000) != 0) ... because of the macro: #define SCB_complete(s) ((s&0x8000)!=0) so rsst can only become either 0x8000 or 0, but in the latter case the loop ends, I think the wrong timed out status is printed.

2008-12-29netns: foreach_netdev_safe is insufficient in default_device_exitEric W. Biederman
During network namespace teardown we either move or delete all of the network devices associated with a network namespace. In the case of veth devices deleting one will also delete it's pair device. If both devices are in the same network namespace then for_each_netdev_safe is insufficient as next may point to the second veth device we have deleted. To avoid problems I do what we do in __rtnl_kill_links and restart the scan of the device list, after we have deleted a device. Currently dev_change_netnamespace does not appear to suffer from this problem, but wireless devices are also paired and likely should be moved between network namespaces together. So I have errored on the side of caution and restart the scan of the network devices in that case as well. Signed-off-by: Eric W. Biederman <ebiederm@aristanetworks.com> Signed-off-by: David S.

2008-12-30kvm-s390: implement config_changed for virtio on s390Christian Borntraeger
This patch implements config_changed for the s390 virtio transport. We use the least significant bit of the interrupt parameter field to decide, if this interrupt should call the virtio virtqueue callback or the config_changed callback. This method is compatible with old host and guest code. Old 64 bit guests will not check the bit and trigger a harmless additional vring_interrupt call. Old host code will never set this bit, this is also safe. This patch also takes care of a potential future 31 bit virtio transport for s390. On 31 bit _LC_PFAULT_INTPARM and __LC_EXT_PARAMS are identical. We exploit the alignment of the token and fold the change bit into the lsb of the token itself.

2008-12-30virtio_console: support console resizingChristian Borntraeger
this patch uses the new hvc callback hvc_resize to set the window size which allows to change the tty size of hvc_console via a hvc_resize function. I have added a new feature bit VIRTIO_CONSOLE_F_SIZE. The driver will change the window size on tty open and via the config_changed callback of the transport. Currently lguest and kvm_s390 have not implemented this callback, but the callback can be implemented at a later point in time.

2008-12-30virtio: block: dynamic maximum segmentsRusty Russell
Enhance the driver to handle whatever maximum segment number the host tells us to handle. Do to this, we need to allocate the scatterlist dynamically. We set max_phys_segments and max_hw_segments to the same value (1 if the host doesn't tell us, since that's safest and all known hosts do tell us). Note that kmalloc'ing the structure for large sg_elems might be problematic: the fix for this is sg_table, but that requires more work. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2008-12-30virtio: set max_segment_size and max_sectors to infinite.Rusty Russell

2008-12-30virtio: Don't use PAGE_SIZE in virtio_pci.cRusty Russell

2008-12-30virtio: struct device - replace bus_id with dev_name(), dev_set_name()Kay Sievers
This patch is part of a larger patch series which will remove the "char bus_id[20]" name string from struct device. The device name is managed in the kobject anyway, and without any size limitation, and just needlessly copied into "struct device". To set and read the device name dev_name(dev) and dev_set_name(dev) must be used. If your code uses static kobjects, which it shouldn't do, "const char *init_name" can be used to statically provide the name the registered device should have. At registration time, the init_name field is cleared, to enforce the use of dev_name(dev) to access the device name at a later time. We need to get rid of all occurrences of bus_id in the entire tree to be able to enable the new interface. Please apply this patch, and possibly convert any remaining remaining occurrences of bus_id. We want to submit a patch to -next, which will remove bus_id from "struct device", to find the remaining pieces to convert, and finally switch over to the new api, which will remove the 20 bytes array and does no longer have a size limitation.

2008-12-30cpumask: Use nr_cpu_ids in seq_cpumaskRusty Russell
Impact: cleanup, futureproof nr_cpu_ids is the (badly named) runtime limit on possible CPU numbers; ie. the variable version of NR_CPUS. With the new cpumask operators, only bits less than this are defined. So we should use it everywhere, rather than NR_CPUS. Eventually this will make it possible to allocate cpumasks of the minimal length at runtime.

2008-12-30cpumask: smp_call_function_many()Rusty Russell
Impact: Implementation change to remove cpumask_t from stack. Actually change smp_call_function_mask() to smp_call_function_many(). We avoid cpumasks on the stack in this version. (S390 has its own version, but that's going away apparently). We have to do some dancing to figure out if 0 or 1 other cpus are in the mask supplied and the online mask without allocating a tmp cpumask. It's still fairly cheap. We allocate the cpumask at the end of the call_function_data structure: if allocation fails we fallback to smp_call_function_single rather than using the baroque quiescing code (which needs a cpumask on stack).
