2006-06-23[NET]: Avoid allocating skb in skb_padHerbert Xu2-7/+3
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.

2006-06-18[NET]: Add netif_tx_lockHerbert Xu1-1/+3
Various drivers use xmit_lock internally to synchronise with their transmission routines. They do so without setting xmit_lock_owner. This is fine as long as netpoll is not in use. With netpoll it is possible for deadlocks to occur if xmit_lock_owner isn't set. This is because if a printk occurs while xmit_lock is held and xmit_lock_owner is not set can cause netpoll to attempt to take xmit_lock recursively. While it is possible to resolve this by getting netpoll to use trylock, it is suboptimal because netpoll's sole objective is to maximise the chance of getting the printk out on the wire. So delaying or dropping the message is to be avoided as much as possible. So the only alternative is to always set xmit_lock_owner. The following patch does this by introducing the netif_tx_lock family of functions that take care of setting/unsetting xmit_lock_owner. I renamed xmit_lock to _xmit_lock to indicate that it should not be used directly. I didn't provide irq versions of the netif_tx_lock functions since xmit_lock is meant to be a BH-disabling lock. This is pretty much a straight text substitution except for a small bug fix in winbond. It currently uses netif_stop_queue/spin_unlock_wait to stop transmission. This is unsafe as an IRQ can potentially wake up the queue. So it is safer to use netif_tx_disable. The hamradio bits used spin_lock_irq but it is unnecessary as xmit_lock must never be taken in an IRQ handler. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

Well, this is not 100% if when the card fires two consecutive interrupts. Though unlikely, it's better to protect early than seeing some "weird" bugs one day. I proposed attached patch. If you can help to test, that will be appreciated (I cannot see the lockdep warning on my box somehow).

2006-04-25[PATCH] ipw2200: Enable rtap interface for RF promiscuous mode while associatedZhu Yi3-27/+673
With this patch, a new promiscuous mode is enabled. If the module is loaded with the rtap_iface=1 module parameter, two interfaces will be created (instead of just one). The second interface is prefixed 'rtap' and provides received 802.11 frames on the current channel to user space in a radiotap header format. Example usage: % modprobe ipw2200 rtap_iface=1 % iwconfig eth1 essid MyNetwork % dhcpcd eth1 % tcpdump -i rtap0 If you do not specify 'rtap_iface=1' then the rtap interface will not be created and you will need to turn it on via: % echo 1 > /sys/bus/pci/drivers/ipw2200/*/rtap_iface You can filter out what type of information is passed to user space via the rtap_filter sysfs entry. Currently you can tell the driver to transmit just the headers (which will provide the RADIOTAP and IEEE 802.11 header but not the payload), to filter based on frame control type (Management, Control, or Data), and whether to report transmitted frames, received frames, or both. The transmit frame reporting is based on a patch by Stefan Rompf. Filters can be get and set via a sysfs interface. For example, set the filter to only send headers (0x7), don't report Tx'd frames (0x10), and don't report data frames (0x100): % echo 0x117 > /sys/bus/pci/drivers/ipw2200/*/rtap_filter All your packets are belong to us: % tethereal -n -i rtap0 Signed-off-by: James Ketrenos <jketreno@linux.intel.com> Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: John W.
