2010-01-06S390: dasd: support DIAG access for read-only devicesStefan Weinhuber
commit 22825ab7693fd29769518a0d25ba43c01a50092a upstream. When a DASD device is used with the DIAG discipline, the DIAG initialization will indicate success or error with a respective return code. So far we have interpreted a return code of 4 as error, but it actually means that the initialization was successful, but the device is read-only. To allow read-only devices to be used with DIAG we need to accept a return code of 4 as success. Re-initialization of the DIAG access is also part of the DIAG error recovery. If we find that the access mode of a device has been changed from writable to read-only while the device was in use, we print an error message.

2010-01-06pata_cmd64x: fix overclocking of UDMA0-2 modesBartlomiej Zolnierkiewicz
commit 509426bd46ad0903dca409803e0ee3d30f99f1e8 upstream. adev->dma_mode stores the transfer mode value not UDMA mode number so the condition in cmd64x_set_dmamode() is always true and the higher UDMA clock is always selected. This can potentially result in data corruption when UDMA33 device is used, when 40-wire cable is used or when the error recovery code decides to lower the device speed down. The issue was introduced in the commit 6a40da0 ("libata cmd64x: whack into a shape that looks like the documentation") which goes back to kernel 2.6.20.

2010-01-06Libertas: fix buffer overflow in lbs_get_essid()Daniel Mack
commit 45b241689179a6065384260242637cf21dabfb2d upstream. The libertas driver copies the SSID buffer back to the wireless core and appends a trailing NULL character for termination. This is a) unnecessary because the buffer is allocated with kzalloc and is hence already NULLed when this function is called, and b) for priv->curbssparams.ssid_len == 32, it writes back one byte too much which causes memory corruptions. Fix this by removing the extra write.

2009-12-18pata_hpt{37x|3x2n}: fix timing register masks (take 2)Sergei Shtylyov
commit 5600c70e576199a7552e1c0fff43f3fe16f5566e upstream. These drivers inherited from the older 'hpt366' IDE driver the buggy timing register masks in their set_piomode() metods. As a result, too low command cycle active time is programmed for slow PIO modes. Quite fortunately, it's later "fixed up" by the set_dmamode() methods which also "helpfully" reprogram the command timings, usually to PIO mode 4; unfortunately, setting an UltraDMA mode #N also reprograms already set PIO data timings, usually to MWDMA mode # max(N, 2) timings... However, the drivers added some breakage of their own too: the bit that they set/clear to control the FIFO is sometimes wrong -- it's actually the MSB of the command cycle setup time; also, setting it in DMA mode is wrong as this bit is only for PIO actually and clearing it for PIO modes is not needed as no mode in any timing table has it set... Fix all this, inverting the masks while at it, like in the 'hpt366' and 'pata_hpt366' drivers; bump the drivers' versions, accounting for recent patches that forgot to do it...

This is commit f9c99bb8b3a1ec81af68d484a551307326c2e933 back-ported to 2.6.27.39. This patch (as1254-2) splits up the shutdown method of usb_serial_driver into a disconnect and a release method. The problem is that the usb-serial core was calling shutdown during disconnect handling, but drivers didn't expect it to be called until after all the open file references had been closed. The result was an oops when the close method tried to use memory that had been deallocated by shutdown.

waiting processes commit 1f95725755ab67f3198df3b5bf7517f926f310ca upstream. The s2255 driver had logic which aborted processing of a video frame if there was no process waiting on the video buffer in question. That simply doesn't work when the application is doing things in an asynchronous manner. If the application went to the trouble to queue the buffer in the first place, then the driver should always attempt to complete it - even if the application at that moment has its attention turned elsewhere. Applications which always blocked waiting for I/O on the capture device would not have been affected by this. Applications which *mostly* blocked waiting for I/O on the capture device probably only would have been somewhat affected (frame lossage, at a rate which goes up as the application blocks less). Applications which never blocked on the capture device (e.g. polling only) however would never have been able to receive any video frames, since in that case this "is anyone waiting on this?" check on the buffer never would have evalutated true. This patch just deletes that harmful check against the buffer's wait queue.

2009-12-08V4L/DVB (13109): tda18271: fix signedness issue in ↵Seth Barry
tda18271_rf_tracking_filters_init commit a57c1dcb93e43357ed3f666e5a2b5d5071dd3930 upstream. While having tda18271 module set with debug=17 (cal & info prints) and cal=0 (delay calibration process until first use) - I discovered that during the calibration process, if the frequency test for 69750000 returned a bcal of 0 (see tda18721-fe.c in tda18271_powerscan func) that the tuner wouldn't be able to pickup any of the frequencies in the range (all the other frequencies bands returned bcal=1). I spent some time going over the code and the NXP's tda18271 spec (ver.4 of it i think) and adding a lot of debug prints and walking/stepping through the calibration process. I found that when the powerscan fails to find a frequency, the rf calibration is not run and the default value is supposed to be used in its place (pulled from the RF_CAL_map table) - but something was getting goofed up there. Now, my c coding skills are very rusty, but i think root of the problem is a signedness issue with the math operation for calculating the rf_a1 and rf_a2 values in tda18271_rf_tracking_filters_init func, which results in values like 20648 for rf_a1 (when it should probably have a value like 0, or so slightly negative that it should be zero - this bad value for rf_a1 would in turn makes the approx calc within tda18271c2_rf_tracking_filters_correction go out of whack). The simplest solution i found was to explicitly convert the signedness of the denominator to avoid the implicit conversion. The values placed into the u32 rf_freq array should never exceed about 900mhz, so i think the s32 max value shouldn't be an issue in this case. I've tested it out a little, and even when i get a bcal=0 with the modified code, the default calibration value gets used, rf_a1 is zero, and the tuner seems to lock on the stream and mythtv seems to play it fine.

commit d9d5283228d0c752f199c901fff6e1405dc91bcb upstream. In mii monitor mode, bond_check_dev_link() calls the the ioctl handler of slave devices. It stores the ndo_do_ioctl function pointer to a static (!) ioctl variable and later uses it to call the handler with the IOCTL macro. If another thread executes bond_check_dev_link() at the same time (even with a different bond, which none of the locks prevent), a race condition occurs. If the two racing slaves have different drivers, this may result in one driver's ioctl handler being called with a pointer to a net_device controlled with a different driver, resulting in unpredictable breakage.

commit e9024a059f2c17fb2bfab212ee9d31511d7b8e57 upstream. On a 64-bit kernel, skb->tail is an offset, not a pointer. The libertas usb driver passes it to usb_fill_bulk_urb() anyway, causing interesting crashes. Fix that by using skb->data instead. This highlights a problem with usb_fill_bulk_urb(). It doesn't notice when dma_map_single() fails and return the error to its caller as it should. In fact it _can't_ currently return the error, since it returns void. So this problem was showing up only at unmap time, after we'd already suffered memory corruption by doing DMA to a bogus address.

commit f4b31db92d163df8a639f5a8c8633bdeb6e8432d upstream. When an internal command fails, it should be failed directly without invoking EH. In the original implemetation, this was accomplished by letting internal command bypass failure handling in ata_qc_complete(). However, later changes added post-successful-completion handling to that code path and the success path is no longer adequate as internal command failure path. One of the visible problems is that internal command failure due to timeout or other freeze conditions would spuriously trigger WARN_ON_ONCE() in the success path.

In this patch: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=16dc42e018c2868211b4928f20a957c0c216126c the check was added for another driver to already claim the same device on the same bus. But the returned error code was wrong: to modprobe, the -EEXIST means that _this_ driver is already installed. It therefore doesn't produce the needed error message when _another_ driver is trying to register for the same device. Returning -EBUSY fixes the problem.

2009-11-09b43: Fix Bugzilla #14181 and the bug from the previous 'fix'Larry Finger
commit d50bae33d1358b909ade05ae121d83d3a60ab63f upstream. "b43: Fix PPC crash in rfkill polling on unload" fixed the bug reported in Bugzilla No. 14181; however, it introduced a new bug. Whenever the radio switch was turned off, it was necessary to unload and reload the driver for it to recognize the switch again. This patch fixes both the original bug in #14181 and the bug introduced by the previous patch. It must be stated, however, that if there is a BCM4306/3 with an rfkill switch (not yet proven), then the driver will need an unload/reload cycle to turn the device back on.

2009-10-21usb-serial: fix crash when sub-driver updates firmwareAlan Stern
commit 0a3c8549ea7e94d74a41096d42bc6cdf43d183bf upstream. This patch (as1244) fixes a crash in usb-serial that occurs when a sub-driver returns a positive value from its attach method, indicating that new firmware was loaded and the device will disconnect and reconnect. The usb-serial core then skips the step of registering the port devices; when the disconnect occurs, the attempt to unregister the ports fails dramatically. This problem shows up with Keyspan devices and it might affect others as well. When the attach method returns a positive value, the patch sets num_ports to 0. This tells usb_serial_disconnect() not to try unregistering any of the ports; instead they are cleaned up by destroy_serial().

commit ec57935837a78f9661125b08a5d08b697568e040 upstream. When probing the device in tpm_tis_init the call request_locality uses timeout_a, which wasn't being initalized until after request_locality. This results in request_locality falsely timing out if the chip is still starting. Move the initialization to before request_locality. This probably only matters for embedded cases (ie mine), a BIOS likely gets the TPM into a state where this code path isn't necessary.
