* use irq_handler_t where appropriate * no need to use 'irq' function arg, its already stored in a data struct * rename irq handler 'irq' argument to 'dummy', where the function has been analyzed and proven not to use its first argument. * remove always-false "dev_id == NULL" test from irq handlers * remove pointless casts from void* * declance: irq argument is not const * add KERN_xxx printk prefix * fix minor whitespace weirdness Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2007-10-10[HOSTAP]: set netdev type before registering AP interfaceDaniel Drake
As detailed at https://bugs.gentoo.org/159646 hostap with hostapd confuses udev by presenting 2 interfaces with the same MAC address. Also, at the time of detection, the 'type' attribute is 1, identical to other hostap interfaces. The AP interface is supposed to have type ARPHRD_IEEE80211 (801), but this is not set until after registration. Setting it before register_netdev() is called allows us to avoid this confusion. We can do this by propogating the HOSTAP_INTERFACE type through to hostap_setup_dev(). Signed-off-by: Daniel Drake <dsd@gentoo.org> Signed-off-by: John W.

2007-10-10[PATCH] dev->priv to netdev_priv(dev), for drivers/net/wirelessYoann Padioleau
Replacing accesses to dev->priv to netdev_priv(dev). The replacment is safe when netdev_priv is used to access a private structure that is right next to the net_device structure in memory. Cf http://groups.google.com/group/comp.os.linux.development.system/browse_thread/thread/de19321bcd94dbb8/0d74a4adcd6177bd This is the case when the net_device structure was allocated with a call to alloc_netdev or one of its derivative.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

2005-08-14[PATCH] hostap: Remove experimental PCI bus master/DMA codeJouni Malinen
PCI version of Prism2.5/3 has undocumented DMA support for TX/RX data, but this seems to have some hardware bugs that prevent it from being used properly for TX. RX side could possibly be made to work reliably. Even though DMA support would be very useful for saving host CPU (from about 40% to 5-10% when operating at maximum throughput), it seems to be best to just remove this code finally. The implementation has always been commented out by default and has received very limited testing. The code may have already been broken number of times and I don't have much interested in trying to verify whether it works or not. Getting this out makes it easier to maintain the driver and allows some cleanups that have been partly postponed because of this experimental bus master/DMA code.

Warning fix for 64-bit platforms Hello!

A simple fix would be to use double cast from pointer to long and then to int (and vice versa when int is passed as a pointer). But I prefer a slightly longer patch. I believe that whenever an argument can hold both a pointer and an integer, it should be declared long. long can hold both pointers and integers (except win64, but we are not coding for Windows), it can be cast to both of them and it's never assumed to be a valid pointer, which could be useful for some automatic code checkers.

2005-07-30[PATCH] hostap updateDave Hansen
Create sysfs "device" files for hostap I was writing some scripts to automatically build kismet source lines, and I noticed that hostap devices don't have device files, unlike my prism54 and ipw2200 cards: $ ls -l /sys/class/net/eth0/device /sys/class/net/eth0/device -> ../../../devices/pci0000:00/0000:00:1e.0/0000:02:01.0 $ ls -l /sys/class/net/wifi0 ls: /sys/class/net/wifi0/device: No such file or directory $ ls -l /sys/class/net/wlan0 ls: /sys/class/net/wlan0/device: No such file or directory The following (quite small) patch makes sure that both the wlan and wifi net devices have that pointer to the bus device. This way, I can do things like for i in /sys/class/net/*; do if ! [ -e $i/device/drive ]; then continue; fi; driver=$(basename $(readlink $i/device/driver)) case $driver in hostap*) echo -- hostap,$i,$i-$driver break; ipw2?00) echo -- $driver,$i,$i-$driver break; prism54) echo prism54g,$i esac done Which should generate a working set of source lines for kismet no matter what order I plug the cards in. It might also be handy to have a link between the two net devices, but that's a patch for another day.
