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>
2006-06-23[NET]: Avoid allocating skb in skb_padHerbert Xu
First of all it is unnecessary to allocate a new skb in skb_pad since the existing one is not shared. More importantly, our hard_start_xmit interface does not allow a new skb to be allocated since that breaks requeueing. This patch uses pskb_expand_head to expand the existing skb and linearize it if needed. Actually, someone should sift through every instance of skb_pad on a non-linear skb as they do not fit the reasons why this was originally created. Incidentally, this fixes a minor bug when the skb is cloned (tcpdump, TCP, etc.). As it is skb_pad will simply write over a cloned skb. Because of the position of the write it is unlikely to cause problems but still it's best if we don't do it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2006-02-23r8169: fix broken ring index handling in suspend/resumeFrancois Romieu
rtl8169_hw_start() requires that the descriptor ring indexes be set to zero. Let a deferred invocation of rtl8169_reset_task() handle it. Enabling a few power management bits will not hurt either. suspend/resume is issued with irq on: the spinlock do not need to save the irq flag. Signed-off-by: Francois Romieu <romieu@fr.zoreil.com>

2006-01-29r8169: prevent excessive busy-waitingFrancois Romieu
The MII registers read/write function blindly busy waits for an amount of 1000 us (1 ms), then up to 200 ms. These functions are called from irq disabled context. Depending on the clock management, it triggers lost ticks events. Since the value is way above the standard delay required for mii register access, it strangely looks like a bandaid against posted writes.

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.

2005-05-12 [PATCH] r8169: incoming frame length checkFrancois Romieu
The size of the incoming frame is not correctly checked. The RxMaxSize register (0xDA) does not work as expected and incoming frames whose size exceeds the MTU actually end spanning multiple descriptors. The first Rx descriptor contains the size of the whole frame (or some garbage in its place). The driver does not expect something above the space allocated to the current skb and crashes loudly when it issues a skb_put. The fix contains two parts: - disable hardware Rx size filtering: so far it only proved to be able to trigger some new fancy errors; - drop multi-descriptors frame: as the driver allocates MTU sized Rx buffers, it provides an adequate filtering. As a bonus, wrong descriptors were not returned to the asic after their processing. Signed-off-by: Francois Romieu <romieu@fr.zoreil.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

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!
