* [PATCH] wireless: More WE-21 potential overflows...Jean Tourrilhes2006-10-171-1/+0
| | | | | | | | | | After the Orinoco issue, I did an audit of other drivers for the same issue. Three drivers were NULL terminating the ESSID, which could cause an overflow in WE-21 when the ESSID has maximum size.

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [NET]: Avoid allocating skb in skb_padHerbert Xu2006-06-231-2/+1
| | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] pcmcia: convert DEV_OK to pcmcia_dev_presentDominik Brodowski2006-03-311-1/+1

* [PATCH] pcmcia: use bitfield instead of p_state and stateDominik Brodowski2006-03-311-30/+23
| | | | | | | | | | Instead of the two status values struct pcmcia_device->p_state and state, use descriptive bitfields. Most value-checking in drivers was invalid, as the core now only calls the ->remove() (a.k.a. detach) function in case the attachement _and_ configuration was successful.

* [PATCH] pcmcia: add return value to _config() functionsDominik Brodowski2006-03-311-10/+9
| | | | | | | | Most of the driver initialization isn't done in the .probe function, but in the internal _config() functions.

* [PATCH] pcmcia: default suspend and resume handlingDominik Brodowski2006-03-311-16/+6

* [PATCH] drivers/net/wireless: correct reported ssid lengthsDan Williams2006-01-161-1/+1
| | | | | | | | | | | ESSIDs can technically include NULL characters. Drivers should not be adjusting the length of the ESSID before reporting it in their SIOCGIWESSID handlers.

* [PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe ↵Dominik Brodowski2006-01-061-58/+10
| | | | | | | | | | | | | | | | | | | | | | callback Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified probe() callback. As all in-kernel drivers are changed to this new callback, there will be no temporary backwards-compatibility. Inside a probe() function, each driver _must_ set struct pcmcia_device *p_dev->instance and instance->handle correctly. With these patches, the basic driver interface for 16-bit PCMCIA drivers now has the classic four callbacks known also from other buses: int (*probe) (struct pcmcia_device *dev); void (*remove) (struct pcmcia_device *dev); int (*suspend) (struct pcmcia_device *dev); int (*resume) (struct pcmcia_device *dev); Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

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!
