"I recently (on a flight) I found out that when I boot with the hard-switch activated, so turning off all wireless activity on my laptop, the state is not correctly announced in /dev/rfkill (reading it with rfkill command, or my own gnome applet)... After turning off and on again the hard-switch the events were right." We can fix this by querying the firmware at load time and calling rfkill_set_hw_state().

The move away from having drivers assign wireless handlers, in favour of making cfg80211 assign them, broke the sysfs registration (the wireless/ dir went missing) because the handlers are now assigned only after registration, which is too late. Fix this by special-casing cfg80211-based devices, all of which are required to have an ieee80211_ptr, in the sysfs code, and also using get_wireless_stats() to have the same values reported as in procfs.

The wireless extensions have a copy_from_user to a local stack array "essid", but both me and gcc have failed to find where the bounds for this copy are located in the code. This patch adds some basic sanity checks for the copy length to make sure that we don't overflow the stack buffer.

Multiple problems were reported due to interaction between wpa_supplicant and the wext compat code in cfg80211, which appear to be due to it not getting any bss pointer here when wpa_supplicant sets all parameters -- do that now. We should still get the bss after doing an extra scan, but that appears to increase the time we need for connecting enough to sometimes cause timeouts.

When hardware or uCode problem occurs driver captures significant information from device to enable debugging. The format of this information is different between 3945 and 4965 and later devices, yet currently the 3945 uses the 4965 and later format. Fix this by adding a new library call that is initialized to the correct formatting routine based on device. This moves the iwlagn event and error log handling back to iwl-agn.c to make it part of iwlagn module. Also remove the 3945 sysfs file that triggers dump of event log - there is already a debugfs file that can do it for all drivers.

We keep track of where to write into a buffer by keeping a count of how much has been written so far. When writing to the buffer we thus take the buffer pointer and adding the count of what has been written so far. Keeping track of what has been written so far is done by incrementing this number every time something is written to the buffer with how much has been written at that time. Currently this number is incremented incorrectly when using the "hex_dump_to_buffer" call to add data to the buffer. Fix this by only adding what has been added to the buffer in that call instead of what has been added since beginning of buffer. Issue was discovered and discussed during testing of https://bugzilla.redhat.com/show_bug.cgi?id=464598 .

Though, there are few other issues with suspend/resume in this driver. The intention of calling free_irq() in suspend() was to avoid any possible spurious interrupts (see commit 5b039e68 "3c59x PM fixes"). But, - On resume, the driver was requesting IRQ just after pci_set_master(), but before vortex_up() (which actually resets 3c59x chips). - Issuing free_irq() on a shared IRQ doesn't guarantee that a buggy HW won't trigger spurious interrupts in another driver that requested the same interrupt. So, if we want to protect from unexpected interrupts, then on suspend we should issue disable_irq(), not free_irq().
