| * [PPP] generic: Fix receive path data clobbering & non-linear handlingHerbert Xu2007-09-171-19/+25
| | | | | | | | | | | | | | | | | | | | This patch adds missing pskb_may_pull calls to deal with non-linear packets that may arrive from pppoe or pppol2tp. It also copies cloned packets before writing over them. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | It's rude to write over data that other people are still using. So call skb_cow_head before PPP proceeds to modify the skb data. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
| * [NET] skbuff: Add skb_cow_headHerbert Xu2007-09-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | This patch adds an optimised version of skb_cow that avoids the copy if the header can be modified even if the rest of the payload is cloned. This can be used in encapsulating paths where we only need to modify the header. As it is, this can be used in PPPOE and bridging.

| * [PPP] pppoe: Fill in header directly in __pppoe_xmitHerbert Xu2007-09-171-11/+9
| | | | | | | | | | | | | | | | | | | | | | This patch removes the hdr variable (which is copied into the skb) and instead sets the header directly in the skb. It also uses __skb_push instead of skb_push since we've just checked using skb_cow for enough head room. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

| * [PPP] pppoe: Fix data clobbering in __pppoe_xmit and return valueHerbert Xu2007-09-171-37/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function __pppoe_xmit modifies the skb data and therefore it needs to copy and skb data if it's cloned. In fact, it currently allocates a new skb so that it can return 0 in case of error without freeing the original skb. This is totally wrong because returning zero is meant to indicate congestion whereupon pppoe is supposed to wake up the upper layer once the congestion subsides. This makes sense for ppp_async and ppp_sync but is out-of-place for pppoe. This patch makes it always return 1 and free the skb.

| * | [PATCH] bcm43xx: Fix cancellation of work queue crashesLarry Finger2007-09-143-10/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A crash upon booting that is caused by bcm43xx has been reported [1] and found to be due to a work queue being reinitialized while work on that queue is still pending. This fix modifies the shutdown of work queues and prevents periodic work from being requeued during shutdown. With this patch, no more crashes on reboot were observed by the original reporter. I do not get that particular failure on my system; however, when running a large number of ifdown/ifup sequences, my system would kernel panic with the 'caps lock' light blinking at roughly a 1 Hz rate. In addition, there were infrequent failures in the firmware that resulted in 'IRQ READY TIMEOUT' errors. With this patch, no more of the first type of failure occur, and incidence of the second type is greatly reduced.

* | | spidernet: fix interrupt reason recognitionIshizaki Kou2007-09-131-8/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch solves a problem that the spidernet driver sometimes fails to handle IRQ. The problem happens because, - In Cell architecture, interrupts may arrive at an interrupt controller, even if they are masked by the setting on registers of devices. It happens when interrupt packets are sent just before the interrupts are masked. - spidernet interrupt handler compares interrupt reasons with interrupt masks, so when such interrupts occurs, spidernet interrupt handler returns IRQ_NONE. - When all of interrupt handler return IRQ_NONE, linux kernel disables the IRQ and it no longer delivers interrupts to the interrupt handlers. spidernet doesn't work after above sequence, because it can't receive interrupts. This patch changes spidernet interrupt handler that it compares interrupt reason with SPIDER_NET_INTX_MASK_VALUE.

It makes sense not to take the physical port state into account on machines with more logical partitions that communicate with each other.

* | [TG3]: Workaround MSI bug on 5714/5780.Michael Chan2007-09-111-2/+11
|/ | | | | | | | | | | | | | | | | | | | A hardware bug was revealed after a recent PCI MSI patch was made to always disable legacy INTX when enabling MSI. The 5714/5780 chips will not generate MSI when INTX is disabled, causing MSI failure messages to be reported, and another patch was made to workaround the problem by disabling MSI on ServerWorks HT1000 bridge chips commonly found with the 5714. We workaround this chip bug by enabling INTX after we enable MSI and after we resume from suspend. Update version to 3.81. This problem was discovered by David Miller.
