* drivers/net/usb/hso.c: prevent reading uninitialized memoryDan Rosenberg2010-09-161-0/+2
| | | | | | | | | | | | | Fixed formatting (tabs and line breaks). The TIOCGICOUNT device ioctl allows unprivileged users to read uninitialized stack memory, because the "reserved" member of the serial_icounter_struct struct declared on the stack in hso_get_count() is not altered or zeroed before being copied back to the user. This patch takes care of it. Signed-off-by: Dan Rosenberg <dan.j.rosenberg@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | This patch removes the setting of the low_latency flag. tty_flip_buffer_push() is occasionally being called in irq context, which causes a hang if the low_latency flag is set.

* drivers/net: Remove unnecessary returns from void function()sJoe Perches2010-05-141-2/+0
| | | | | | | | | | | | | | | | | | | | | | This patch removes from drivers/net/ all the unnecessary return; statements that precede the last closing brace of void functions. It does not remove the returns that are immediately preceded by a label as gcc doesn't like that. It also does not remove null void functions with return. Done via: $ grep -rP --include=*.[ch] -l "return;\n}" net/ | \ xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }' with some cleanups by hand.

* net: Add DEVTYPE support for Ethernet based devicesMarcel Holtmann2009-09-111-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Ethernet framing is used for a lot of devices these days. Most prominent are WiFi and WiMAX based devices. However for userspace application it is important to classify these devices correctly and not only see them as Ethernet devices. The daemons like HAL, DeviceKit or even NetworkManager with udev support tries to do the classification in userspace with a lot trickery and extra system calls. This is not good and actually reaches its limitations. Especially since the kernel does know the type of the Ethernet device it is pretty stupid. To solve this problem the underlying device type needs to be set and then the value will be exported as DEVTYPE via uevents and available within udev. # cat /sys/class/net/wlan0/uevent DEVTYPE=wlan INTERFACE=wlan0 IFINDEX=5 This is similar to subsystems like USB and SCSI that distinguish between hosts, devices, disks, partitions etc. The new SET_NETDEV_DEVTYPE() is a convenience helper to set the actual device type. All device types are free form, but for convenience the same strings as used with RFKILL are choosen. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch completely rewrites the rfkill core to address the following deficiencies: * all rfkill drivers need to implement polling where necessary rather than having one central implementation * updating the rfkill state cannot be done from arbitrary contexts, forcing drivers to use schedule_work and requiring lots of code * rfkill drivers need to keep track of soft/hard blocked internally -- the core should do this * the rfkill API has many unexpected quirks, for example being asymmetric wrt. alloc/free and register/unregister * rfkill can call back into a driver from within a function the driver called -- this is prone to deadlocks and generally should be avoided * rfkill-input pointlessly is a separate module * drivers need to #ifdef rfkill functions (unless they want to depend on or select RFKILL) -- rfkill should provide inlines that do nothing if it isn't compiled in * the rfkill structure is not opaque -- drivers need to initialise it correctly (lots of sanity checking code required) -- instead force drivers to pass the right variables to rfkill_alloc() * the documentation is hard to read because it always assumes the reader is completely clueless and contains way TOO MANY CAPS * the rfkill code needlessly uses a lot of locks and atomic operations in locked sections * fix LED trigger to actually change the LED when the radio state changes -- this wasn't done before Tested-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> [thinkpad] Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* net: remove driver_data direct access of struct deviceGreg Kroah-Hartman2009-05-011-2/+2
| | | | | | | | | | | | In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used. These functions have been around since the beginning, so are backwards compatible with all older kernel versions.
