| * netpoll queue cleanupStephen Hemminger2006-12-02
| | | | | | | | | | | | | | | | | | | | | | | | The beast had a long and not very happy history. At one point, a friend (netdump) had asked that he open up a little. Well, the friend was long gone now, and the beast had this dangling piece hanging (netpoll_queue). It wasn't hard to stitch the netpoll_queue back in where it belonged and make everything tidy.

| * netpoll retry cleanupStephen Hemminger2006-12-02
| | | | | | | | | | | | | | | | | | | | | | | | The netpoll beast was still not happy. If the beast got clogged pipes, it tended to stare blankly off in space for a long time. The problem couldn't be completely fixed because the beast talked with irq's disabled. But it could be made less painful and shorter. Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
| * netpoll deferred transmit pathStephen Hemminger2006-12-02
| | | | | | | | | | | | | | | | | | | | | | | | | | When the netpoll beast got busy, he tended to babble. Instead of talking out of his large mouth as normal, he tended to try to snort out other orifices. This lead to words (skbs) ending up in odd places (like NIT) that he did not intend. The normal way of talking wouldn't work, but he could at least change to using the same tone all the time. Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
| * netpoll setup error handlingStephen Hemminger2006-12-02
| | | | | | | | | | | | | | | | | | The beast was not always healthy. When it was sick, it tended to be laconic and not tell anyone the real problem. A few small changes had it telling the world about its problems, if they really wanted to hear. Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
| * netpoll per device txqStephen Hemminger2006-12-02
| | | | | | | | | | | | | | | | | | When the netpoll beast got really busy, it tended to clog things, so it stored them for later. But the beast was putting all it's skb's in one basket. This was bad because maybe some pipes were clogged and others were not. Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
| * netpoll info leakStephen Hemminger2006-12-02
| | | | | | | | | | | | | | | | | | | | | | | | | | After looking harder, Steve noticed that the netpoll beast leaked a little every time it shutdown for a nap. Not a big leak, but a nuisance kind of thing. He took out his refcount duct tape and patched the leak. It was overkill since there was already other locking in that area, but it looked clean and wouldn't attract fleas. Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
| * netpoll: private skb pool (rev3)Stephen Hemminger2006-12-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was a dark and stormy night when Steve first saw the netpoll beast. The beast was odd, and misshapen but not extremely ugly. "Let me take off one of your warts" he said. This wart is where you tried to make an skb list yourself. If the beast had ever run out of memory, he would have stupefied himself unnecessarily. The first try was painful, so he tried again till the bleeding stopped. And again, and again... Signed-off-by: Stephen Hemminger <shemminger@osdl.org>

| * [NET]: Size listen hash tables using backlog hintEric Dumazet2006-12-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently allocate a fixed size (TCP_SYNQ_HSIZE=512) slots hash table for each LISTEN socket, regardless of various parameters (listen backlog for example) On x86_64, this means order-1 allocations (might fail), even for 'small' sockets, expecting few connections. On the contrary, a huge server wanting a backlog of 50000 is slowed down a bit because of this fixed limit. This patch makes the sizing of listen hash table a dynamic parameter, depending of : - net.core.somaxconn tunable (default is 128) - net.ipv4.tcp_max_syn_backlog tunable (default : 256, 1024 or 128) - backlog value given by user application (2nd parameter of listen()) For large allocations (bigger than PAGE_SIZE), we use vmalloc() instead of kmalloc(). We still limit memory allocation with the two existing tunables (somaxconn & tcp_max_syn_backlog). So for standard setups, this patch actually reduce RAM usage.

* | WorkStruct: Pass the work_struct pointer instead of context dataDavid Howells2006-11-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pass the work_struct pointer to the work function rather than context data. The work function can use container_of() to work out the data. For the cases where the container of the work_struct may go away the moment the pending bit is cleared, it is made possible to defer the release of the structure by deferring the clearing of the pending bit. To make this work, an extra flag is introduced into the management side of the work_struct. This governs auto-release of the structure upon execution. Ordinarily, the work queue executor would release the work_struct for further scheduling or deallocation by clearing the pending bit prior to jumping to the work function. This means that, unless the driver makes some guarantee itself that the work_struct won't go away, the work function may not access anything else in the work_struct or its container lest they be deallocated.. This is a problem if the auxiliary data is taken away (as done by the last patch). However, if the pending bit is *not* cleared before jumping to the work function, then the work function *may* access the work_struct and its container with no problems. But then the work function must itself release the work_struct by calling work_release(). In most cases, automatic release is fine, so this is the default. Special initiators exist for the non-auto-release case (ending in _NAR). Signed-Off-By: David Howells <dhowells@redhat.com>
* | WorkStruct: Separate delayable and non-delayable events.David Howells2006-11-22
|/ | | | | | | | | | | | Separate delayable work items from non-delayable work items be splitting them into a separate structure (delayed_work), which incorporates a work_struct and the timer_list removed from work_struct. The work_struct struct is huge, and this limits it's usefulness. On a 64-bit architecture it's nearly 100 bytes in size. This reduces that by half for the non-delayable type of event.

* [NET]: Set truesize in pskb_copyHerbert Xu2006-11-07

| | | | | | | | | | | We have seen a couple of __alloc_pages() failures due to fragmentation, there is plenty of free memory but no large order pages available. I think the problem is in sock_alloc_send_pskb(), the gfp_mask includes __GFP_REPEAT but its never used/passed to the page allocator. Shouldnt the gfp_mask be passed to alloc_skb() ?

* [NET]: Fix segmentation of linear packetsHerbert Xu2006-10-30
| | | | | | | | | | | | | | | | skb_segment fails to segment linear packets correctly because it tries to write all linear parts of the original skb into each segment. This will always panic as each segment only contains enough space for one MSS. This was not detected earlier because linear packets should be rare for GSO. In fact it still remains to be seen what exactly created the linear packets that triggered this bug. Basically the only time this should happen is if someone enables GSO emulation on an interface that does not support SG.
