2008-09-24wireless: Read scan flags correctly on x86-64David Kilroy
The SIOCSIWSCAN handler is passed data in an iw_point structure. Some drivers erronously use an iw_param instead. On 32 bit architectures the difference isn't noticed as the flags parameter tends to be the only one used by scan handlers and is at the same offset. On 64 bit architectures the pointer in the iw_point structure means the flag parameter is at different offsets in these structures. Thanks to Jean Tourrilhes for tracking this down for orinoco, and Pavel Roskin for confirming the fix and identifying other suspect handlers.

2008-06-16wext: Emit event stream entries correctly when compat.David S. Miller
Three major portions to this change: 1) Add IW_EV_COMPAT_LCP_LEN, IW_EV_COMPAT_POINT_OFF, and IW_EV_COMPAT_POINT_LEN helper defines. 2) Delete iw_stream_check_add_*(), they are unused. 3) Add iw_request_info argument to iwe_stream_add_*(), and use it to size the event and pointer lengths correctly depending upon whether IW_REQUEST_FLAG_COMPAT is set or not. 4) The mechanical transformations to the drivers and wireless stack bits to get the iw_request_info passed down into the routines modified in #3. Also, explicit references to IW_EV_LCP_LEN are replaced with iwe_stream_lcp_len(info). With a lot of help and bug fixes from Masakazu Mokuno. Signed-off-by: David S. Miller <davem@davemloft.net>

The code we calculated that host-endian for had been duplicated several time - it finds the 802.11 MAC header length by the first two bytes of packet; taken into a new helper (header_len(__le16 ctl)).

2007-07-17Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki
Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

2007-07-10[PATCH] airo: fix a race causing initialization failuresMichal Schmidt
Matteo Croce reported Aironet initialization failures. They were caused by a race in airo. airo finds a free interface name, then initializes the card and finally registers the interface. Another device may get the same name in the meantime. The reason airo gets its name early is to use it in informative printks and to name the resources it requests. The printks will be just fine without the interface name and the resources can use the driver's name - that's what other network drivers do anyway. One of the talkative functions is setup_card(). It is called once before registration and can be called later again. Let's have an empty dev->name during the first call, so it doesn't print the ugly "airo(eth%d)" message.

2007-04-28[PATCH] airo: Make /sys/bus/pci/drivers/airo/{,un}bind workMichal Schmidt
The way airo.c keeps track of all its devices is complicated and buggy as well (del_airo_dev forgets to free the memory add_airo_dev allocates). It's cleaner to use the standard list primitives. While we're at it, it's not necessary to put PCI cards in the list, because the kernel already keeps track of them. We can take advantage of it and use the .remove callback as it was meant to be.
