2009-09-30net: Make setsockopt() optlen be unsigned.David S. Miller
This provides safety against negative optlen at the type level instead of depending upon (sometimes non-trivial) checks against this sprinkled all over the the place, in each and every implementation. Based upon work done by Arjan van de Ven and feedback from Linus Torvalds. Signed-off-by: David S. Miller <davem@davemloft.net>

2009-09-28sony-laptop: check for rfkill hard block at load timeAlan Jenkins
"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().

2009-09-28iwlwifi: fix 3945 ucode info retrieval after failureReinette Chatre
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.

2009-09-28iwlwifi: fix debugfs buffer handlingReinette Chatre
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 . When a user views any of these files they will see something like: [ 179.355202] ------------[ cut here ]------------ [ 179.355209] WARNING: at ../lib/vsprintf.c:989 vsnprintf+0x5ec/0x5f0() [ 179.355212] Hardware name: VGN-Z540N [ 179.355213] Modules linked in: i915 drm i2c_algo_bit i2c_core ipv6 acpi_cpufreq cpufreq_userspace cpufreq_powersave cpufreq_ondemand cpufreq_conservative cpufreq_stats freq_table container sbs sbshc arc4 ecb iwlagn iwlcore joydev led_class mac80211 af_packet pcmcia psmouse sony_laptop cfg80211 iTCO_wdt iTCO_vendor_support pcspkr serio_raw rfkill intel_agp video output tpm_infineon tpm tpm_bios button battery yenta_socket rsrc_nonstatic pcmcia_core processor ac evdev ext3 jbd mbcache sr_mod sg cdrom sd_mod ahci libata scsi_mod ehci_hcd uhci_hcd usbcore thermal fan thermal_sys [ 179.355262] Pid: 5449, comm: cat Not tainted 2.6.31-wl-54419-ge881071 #62 [ 179.355264] Call Trace: [ 179.355267] [<ffffffff811ad14c>] ? vsnprintf+0x5ec/0x5f0 [ 179.355271] [<ffffffff81041348>] warn_slowpath_common+0x78/0xd0 [ 179.355275] [<ffffffff810413af>] warn_slowpath_null+0xf/0x20 [ 179.355277] [<ffffffff811ad14c>] vsnprintf+0x5ec/0x5f0 [ 179.355280] [<ffffffff811ad23d>] ? scnprintf+0x5d/0x80 [ 179.355283] [<ffffffff811ad23d>] scnprintf+0x5d/0x80 [ 179.355286] [<ffffffff811aed29>] ? hex_dump_to_buffer+0x189/0x340 [ 179.355290] [<ffffffff810e91d7>] ? __kmalloc+0x207/0x260 [ 179.355303] [<ffffffffa02a02f8>] iwl_dbgfs_nvm_read+0xe8/0x220 [iwlcore] [ 179.355306] [<ffffffff811a9b62>] ? __up_read+0x92/0xb0 [ 179.355310] [<ffffffff810f0988>] vfs_read+0xc8/0x1a0 [ 179.355313] [<ffffffff810f0b50>] sys_read+0x50/0x90 [ 179.355316] [<ffffffff8100bd6b>] system_call_fastpath+0x16/0x1b [ 179.355319] ---[ end trace 2383d0d5e0752ca0 ]--- Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

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 5b039e681b8c5f30aac9cc04385 "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(). Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: David S.

2009-09-24memstick: move dev_dbgJiri Slaby
id_reg.if_mode might be unitialized when (*mrq)->error is nonzero. move dev_dbg() inside the if so that we are sure we can use id_reg values.

2009-09-24edac: core: remove completion-wait for complete with rcu_barrierJesper Dangaard Brouer
Module edac_core.ko uses call_rcu() callbacks in edac_device.c, edac_mc.c and edac_pci.c. They all use a wait_for_completion() scheme, but this scheme it not 100% safe on multiple CPUs. See the _rcu_barrier() implementation which explains why extra precausion is needed. The patch adds a comment about rcu_barrier() and as a precausion calls rcu_barrier(). A maintainer needs to look at removing the wait_for_completion code.

2009-09-24edac: fix resource size calculationJulia Lawall
Use the function resource_size, which reduces the chance of introducing off-by-one errors in calculating the resource size. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ struct resource *res; @@ - (res->end - res->start) + 1 + resource_size(res) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Doug Thompson <dougthompson@xmission.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-09-24edac: mpc85xx add mpc83xx supportIra W. Snyder
Add support for the Freescale MPC83xx memory controller to the existing driver for the Freescale MPC85xx memory controller. The only difference between the two processors are in the CS_BNDS register parsing code, which has been changed so it will work on both processors. The L2 cache controller does not exist on the MPC83xx, but the OF subsystem will not use the driver if the device is not present in the OF device tree. I had to change the nr_pages calculation to make the math work out. I checked it on my board and did the math by hand for a 64GB 85xx using 64K pages. In both cases, nr_pages * PAGE_SIZE comes out to the correct value. Signed-off-by: Ira W.

2009-09-24edac: mpc85xx add P2020DS supportYang Shi
Based on Kumar's new compatible types patch, add P2020 into MPC85xx EDAC compatible lists so that EDAC can recognize P2020 meomry controller and L2 cache controller and export the relevant fields to sysfs. EDAC MPC85xx DDR3 support is needed if DDR3 memory stick is installed on a P2020DS board so that EDAC core can recognize DDR3 memory type.

2009-09-24hpet: hpet driver periodic timer setup bug fixesNils Carlson
The periodic interrupt from drivers/char/hpet.c does not work correctly, both when using the periodic capability of the hardware and while emulating the periodic interrupt (when hardware does not support periodic mode). With timers capable of periodic interrupts, the comparator field is first set with the period value followed by set of hidden accumulator, which has the side effect of overwriting the comparator value. This results in wrong periodicity for the interrupts. For, periodic interrupts to work, following steps are necessary, in that order. * Set config with Tn_VAL_SET_CNF bit * Write to hidden accumulator, the value written is the time when the first interrupt should be generated * Write compartor with period interval for subsequent interrupts (http://www.intel.com/hardwaredesign/hpetspec_1.pdf ) When emulating periodic timer with timers not capable of periodic interrupt, driver is adding the period to counter value instead of comparator value, which causes slow drift when using this emulation. Also, driver seems to add hpetp->hp_delta both while setting up periodic interrupt and while emulating periodic interrupts with timers not capable of doing periodic interrupts. This hp_delta will result in slower than expected interrupt rate and should not be used while setting the interval.
