2007-10-17aoe: remove unecessary wrapper functionEd L. Cashin
We can just use skb_mac_header now, and we don't need a wrapper function to perform the cast. Instead of requiring the reader to check aoe.h to look up what an aoe_hdr function does, I'd rather do without it.

2007-10-10[NET]: Make the device list and device lookups per namespace.Eric W. Biederman
This patch makes most of the generic device layer network namespace safe. 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.

2007-10-10Drop 'size' argument from bio_endio and bi_end_ioNeilBrown
As bi_end_io is only called once when the reqeust is complete, the 'size' argument is now redundant. Remove it. Now there is no need for bio_endio to subtract the size completed from bi_size. So don't do that either. While we are at it, change bi_end_io to return void. Signed-off-by: Neil Brown <neilb@suse.de> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-05-03[NET]: Rework dev_base via list_head (v3)Pavel Emelianov
Cleanup of dev_base list use, with the aim to simplify making device list per-namespace. In almost every occasion, use of dev_base variable and dev->next pointer could be easily replaced by for_each_netdev loop. A few most complicated places were converted to using first_netdev()/next_netdev().

2007-04-25[SK_BUFF]: Introduce skb_reset_network_header(skb)Arnaldo Carvalho de Melo
For the common, open coded 'skb->nh.raw = skb->data' operation, so that we can later turn skb->nh.raw into a offset, reducing the size of struct sk_buff in 64bit land while possibly keeping it as a pointer on 32bit. This one touches just the most simple case, next will handle the slightly more "complex" cases. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S.

2006-12-22[PATCH] fix aoe without scatter-gather [Bug 7662]Ed L. Cashin
Fix a bug that only appears when AoE goes over a network card that does not support scatter-gather. The headers in the linear part of the skb appeared to be larger than they really were, resulting in data that was offset by 24 bytes. This patch eliminates the offset data on cards that don't support scatter-gather or have had scatter-gather turned off. There remains an unrelated issue that I'll address in a separate email.

2006-10-18aoe: zero copy write 1 of 2Ed L. Cashin
Avoid memory copy on writes. (This patch depends on fixes in patch 9 to follow.) Although skb->len should not be set when working with linear skbuffs, the skb->tail pointer maintained by skb_put/skb_trim is not relevant to what happens when the skb_fill_page_desc function is called. This issue was raised without comment in linux-kernel and netdev earlier this month: http://thread.gmane.org/gmane.linux.kernel/446474/ http://thread.gmane.org/gmane.linux.network/45444/ So until there is something analogous to skb_put that works for zero-copy write skbuffs, we will do what the other callers of skb_fill_page_desc are doing.

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!
