2006-08-318139cp: pci_get_drvdata(pdev) can not be NULL in suspend handlerFrançois Romieu
1) pci_set_drvdata() is used in cp_{init/remove}_one to initialize/reset driver_data to the relevant value (resp. net_device * and NULL). 2) each of the 3 relevant functions is issued under (device *)->sem: 2.1) pci_unregister_driver -> driver_unregister -> bus_remove_driver -> driver_detach (takes (device *)->sem) -> __device_release_driver(dev) -> dev->bus-remove(dev) (== pci_device_remove) -> drv->remove(pdev) (== cp_remove_one) [...] pci_dev->driver = NULL; 2.2) pci_register_driver -> __pci_register_driver -> driver_register -> bus_add_driver -> driver_attach -> __driver_attach (takes (device *)->sem) -> driver_probe_device(drv, dev) -> dev->bus->probe(dev) (== pci_device_probe) -> _pci_device_probe(drv, pci_dev) -> pci_call_probe(drv, pci_dev, id) -> drv->probe(dev, id) (== cp_init_one) [...] pci_dev->driver = drv; 2.3) suspend_device (takes (device *)->sem) -> dev->bus->suspend(dev) (== pci_device_suspend) checking for drv = pci_dev->driver != NULL [...] -> drv->suspend(pci_dev, state) (== cp_suspend) dev->sem and the state of pci_dev->driver provide the expected result. St Mary's day was a bit rainy here. Signed-off-by: Francois Romieu <romieu@fr.zoreil.com>

2006-06-23[NET]: Merge TSO/UFO fields in sk_buffHerbert Xu
Having separate fields in sk_buff for TSO/UFO (tso_size/ufo_size) is not going to scale if we add any more segmentation methods (e.g., DCCP). So let's merge them. They were used to tell the protocol of a packet. This function has been subsumed by the new gso_type field. This is essentially a set of netdev feature bits (shifted by 16 bits) that are required to process a specific skb. As such it's easy to tell whether a given device can process a GSO skb: you just have to and the gso_type field and the netdev's features field. I've made gso_type a conjunction. The idea is that you have a base type (e.g., SKB_GSO_TCPV4) that can be modified further to support new features. For example, if we add a hardware TSO type that supports ECN, they would declare NETIF_F_TSO | NETIF_F_TSO_ECN. All TSO packets with CWR set would have a gso_type of SKB_GSO_TCPV4 | SKB_GSO_TCPV4_ECN while all other TSO packets would be SKB_GSO_TCPV4. This means that only the CWR packets need to be emulated in software. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

2005-06-28[NET]: Remove gratuitous use of skb->tail in network drivers.David S. Miller
Many drivers use skb->tail unnecessarily. In these situations, the code roughly looks like: dev = dev_alloc_skb(...); [optional] skb_reserve(skb, ...); ... skb->tail ... But even if the skb_reserve() happens, skb->data equals skb->tail. So it doesn't make any sense to use anything other than skb->data in these cases. Another case was the s2io.c driver directly mucking with the skb->data and skb->tail pointers. It really just wanted to do an skb_reserve(), so that's what the code was changed to do instead. Another reason I'm making this change as it allows some SKB cleanups I have planned simpler to merge. In those cleanups, skb->head, skb->tail, and skb->end pointers are removed, and replaced with skb->head_room and skb->tail_room integers. Signed-off-by: David S.

2005-06-268139cp: safer spin loop for get_statisticsStephen Hemminger
The spin loop in 8139cp is limited to 100 iterations when pulling hardware stats. There is no allowance for processor speed so on a fast machine, the stats may not be available that fast. Also, if the board doesn't return soon enough make sure turn the address back off to prevent later updates when memory has gone away.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
