2016-01-25[media] nuvoton-cir: use IR_DEFAULT_TIMEOUT and consider SAMPLE_PERIODHeiner Kallweit

2016-01-25[media] nuvoton-cir: fix clearing wake fifoHeiner Kallweit
At least on NVT6779D clearing the wake fifo works in learning mode only (although this condition is not mentioned in the chip spec). Setting the clear fifo bit has no effect in wake up mode. Even if clearing the wake fifo should work in wake up mode on other chips this workaround doesn't hurt. If needed the caller of nvt_clear_cir_wake_fifo has to take care of locking.

2016-01-25[media] nuvoton-cir: use request_muxed_region for accessing EFM registersHeiner Kallweit
The two EFM ioports are accessed by drivers for other parts of the Nuvoton Super-IO chips too. Therefore access to these ioports needs to be protected by using request_muxed_region (like it's implemented e.g. in hwmon/nct6775 already).

2016-01-25[media] media: i2c: ov2659: speedup probe if no device connectedGrygorii Strashko
The ov2659 driver performs device detection and initialization in the following way: - send reset command REG_SOFTWARE_RESET - load array of predefined register's setting (~150 values) - read device version REG_SC_CHIP_ID_H/REG_SC_CHIP_ID_L - check version and exit if invalid. As result, for not connected device there will be >~150 i2c transactions executed before device version checking and exit (there are no failures detected because ov2659 declared as I2C_CLIENT_SCCB and NACKs are ignored in this case). Let's fix that by checking the chip version first and start initialization only if it's supported.

changeset 460b6c0831cb ("tvp5150: Add s_stream subdev operation support") broke for em28xx-based devices with uses tvp5150. On those devices, touching the TVP5150_MISC_CTL register causes em28xx to stop streaming. I suspect that it uses the 27 MHz clock provided by tvp5150 to feed em28xx. So, change the logic to do nothing on s_stream if the tvp5150 is not set up to work with V4L2_MBUS_PARALLEL. Tested with Hauppauge WinTV USB 2 model 42012 Rev. C186 (USB ID: 2040:4200).

2016-01-25[media] media: rc: raw: improve FIFO handlingHeiner Kallweit
The FIFO is used for ir_raw_event records, however for some historic reason the FIFO is used on a per byte basis. IMHO this adds unneeded complexity. Therefore set up the FIFO for ir_raw_event records. This also allows to define the FIFO statically as part of ir_raw_event_ctrl instead of having to allocate the FIFO dynamically. In addition: - When writing into the FIFO and it's full return ENOSPC instead of ENOMEM thus making it easier to tell between "FIFO full" and "Dynamic memory allocation failed" when the error is propagated to a higher level. Also add an error message. - When reading from the FIFO check whether it's empty. This is not strictly needed here but kfifo_out is annotated "must check" anyway.

The Authenticode specification is a paragon amongst technical documents, and has this pearl of wisdom to offer: --------------------------------- Authenticode-Specific SignerInfo UnauthenticatedAttributes Structures The following Authenticode-specific data structures are present in SignerInfo authenticated attributes. SpcSpOpusInfo SpcSpOpusInfo is identified by SPC_SP_OPUS_INFO_OBJID (1.3.6.1.4.1.311.2.1.12) and is defined as follows: SpcSpOpusInfo ::= SEQUENCE { programName [0] EXPLICIT SpcString OPTIONAL, moreInfo [1] EXPLICIT SpcLink OPTIONAL, } --#public-- SpcSpOpusInfo has two fields: programName This field contains the program description: If publisher chooses not to specify a description, the SpcString structure contains a zero-length program name. If the publisher chooses to specify a description, the SpcString structure contains a Unicode string. moreInfo This field is set to an SPCLink structure that contains a URL for a Web site with more information about the signer. The URL is an ASCII string. --------------------------------- Which is to say that this is an optional *unauthenticated* field which may be present in the Authenticated Attribute list. This is not how pkcs7 is supposed to work, so when David implemented this, he didn't appreciate the subtlety the original spec author was working with, and missed the part of the sublime prose that says this Authenticated Attribute is an Unauthenticated Attribute. As a result, the code in question simply takes as given that the Authenticated Attributes should be authenticated. But this one should not, individually. Because it says it's not authenticated. It still has to hash right so the TBS digest is correct. So it is both authenticated and unauthenticated, all at once. Truly, a wonder of technical accomplishment. Additionally, pesign's implementation has always attempted to be compatible with the signatures emitted from contemporary versions of Microsoft's signtool.exe. During the initial implementation, Microsoft signatures always produced the same values for SpcSpOpusInfo - {U"Microsoft Windows", "http://www.microsoft.com"} - without regard to who the signer was. Sometime between Windows 8 and Windows 8.1 they stopped including the field in their signatures altogether, and as such pesign stopped producing them in commits c0c4da6 and d79cb0c, sometime around June of 2012. The theory here is that anything that breaks with pesign signatures would also be breaking with signtool.exe sigs as well, and that'll be a more noticed problem for firmwares parsing it, so it'll get fixed. The fact that we've done exactly this bug in Linux code is first class, grade A irony. So anyway, we should not be checking this field for presence or any particular value: if the field exists, it should be at the right place, but aside from that, as long as the hash matches the field is good.

2016-01-25drm/etnaviv: hold object lock while getting pages for coredumpLucas Stach
While all objects that get coredumped have an active IOVA and thus pages already populated, etnaviv_gem_get_pages() still requires the object lock to be held. Signed-off-by: Lucas Stach <l.stach@pengutronix.de>

2016-01-25rtlwifi: rtl8821ae: Fix 5G failure when EEPROM is incorrectly encodedLarry Finger
Recently, it has been reported that D-Link DWA-582 cards, which use an RTL8812AE chip are not able to scan for 5G networks. The problems started with kernel 4.2, which is the first version that had commit d10101a60372 ("rtlwifi: rtl8821ae: Fix problem with regulatory information"). With this patch, the driver went from setting a default channel plan to using the value derived from EEPROM. Bug reports at https://bugzilla.kernel.org/show_bug.cgi?id=111031 and https://bugzilla.redhat.com/show_bug.cgi?id=1279653 are examples of this problem. The problem was solved once I learned that the internal country code was resulting in a regulatory set with only 2.4 GHz channels. With the RTL8821AE chips available to me, the country code was such that both 2.4 and 5 GHz channels are allowed. The fix is to allow both bands even when the EEPROM is incorrectly encoded.

2016-01-25rt2x00: fix monitor mode regressionEli Cooper
Since commit df1404650ccb ("mac80211: remove support for IFF_PROMISC") monitor mode for rt2x00 has been made effectively useless because the hardware filter is configured to drop packets whose intended recipient is not the device, regardless of the presence of monitor mode interfaces. This patch fixes this regression by adding explicit monitor mode support, and by configuring the hardware filter accordingly.

2016-01-25[media] tvp5150: Initialize the chip on probeJavier Martinez Canillas
After power-up, the tvp5150 decoder is in a unknown state until the RESETB pin is driven LOW which reset all the registers and restarts the chip's internal state machine. The init sequence has some timing constraints and the RESETB signal can only be used if the PDN (Power-down) pin is first released. So, the initialization sequence is as follows: 1- PDN (active-low) is driven HIGH so the chip is power-up 2- A 20 ms delay is needed before sending a RESETB (active-low) signal. 3- The RESETB pulse duration is 500 ns. 4- A 200 us delay is needed for the I2C client to be active after reset. This patch used as a reference the logic in the IGEPv2 board file from the ISEE 2.6.37 vendor tree.
