[NET]: Remove in-code externs for some functions from net/core/dev.c

2007-10-24T04:27:56Z

Inconsistent prototype and real type for functions may have worse consequences, than those for variables, so move them into a header. Since they are used privately in net/core, make this file reside in the same place. Signed-off-by: Pavel Emelyanov Signed-off-by: David S. Miller

Driver core: change add_uevent_var to use a struct

2007-10-12T21:51:01Z

This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.

[NET]: Fix running without sysfs

2007-10-10T23:52:46Z

When sysfs support is compiled out the kernel still keeps and maintains the kobject tree. So it is not safe to skip our kobject reference counting or to avoid becoming members of the kobject tree. It is safe to not add the networking specific sysfs attributes. This patch removes the sysfs special cases from net/core/dev.c renames functions from netdev_sysfs_xxxx to netdev_kobject_xxxx and always compiles in net-sysfs.c net-sysfs.c is modified with a CONFIG_SYSFS guard around the parts that are actually sysfs specific.

[NET]: Make NAPI polling independent of struct net_device objects.

2007-10-10T23:47:45Z

Several devices have multiple independant RX queues per net device, and some have a single interrupt doorbell for several queues. In either case, it's easier to support layouts like that if the structure representing the poll is independant from the net device itself. The signature of the ->poll() call back goes from: int foo_poll(struct net_device *dev, int *budget) to int foo_poll(struct napi_struct *napi, int budget) The caller is returned the number of RX packets processed (or the number of "NAPI credits" consumed if you want to get abstract). The callee no longer messes around bumping dev->quota, *budget, etc. because that is all handled in the caller upon return. The napi_struct is to be embedded in the device driver private data structures. Furthermore, it is the driver's responsibility to disable all NAPI instances in it's ->stop() device close handler. Since the napi_struct is privatized into the driver's private data structures, only the driver knows how to get at all of the napi_struct instances it may have per-device. With lots of help and suggestions from Rusty Russell, Roland Dreier, Michael Chan, Jeff Garzik, and Jamal Hadi Salim. Bug fixes from Thomas Graf, Roland Dreier, Peter Zijlstra, Joseph Fannin, Scott Wood, Hans J. Koch, and Michael Chan. [ Ported to current tree and all drivers converted. Integrated Stephen's follow-on kerneldoc additions, and restored poll_list handling to the old style to fix mutual exclusion issues. -DaveM ] Signed-off-by: Stephen Hemminger Signed-off-by: David S.

[NET]: Fix race condition about network device name allocation.

2007-05-19T22:39:25Z

Kenji Kaneshige found this race between device removal and registration. On unregister it is possible for the old device to exist, because sysfs file is still open. A new device with 'eth%d' will select the same name, but sysfs kobject register will fial. The following changes the shutdown order slightly. It hold a removes the sysfs entries earlier (on unregister_netdevice), but holds a kobject reference. Then when todo runs the actual last put free happens.
