commit 46de8ff8 upstream. single-ulpi-bypass is a flag used for older OMAP3 silicon. The flag when set, can excite code that improperly uses the OMAP_UHH_HOSTCONFIG_UPLI_BYPASS define to clear the corresponding bit. Instead it clears all of the other bits disabling all of the ports in the process. Signed-off-by:

commit 7d8b6c63 upstream. This is effectively a revert of 7b9a7ec5 plus fixing it a different way... We found, when trying to run an application from an application which had dropped privs that the kernel does security checks on undefined capability bits. This was ESPECIALLY difficult to debug as those undefined bits are hidden from /proc/$PID/status. Consider a root application which drops all capabilities from ALL 4 capability sets. We assume, since the application is going to set eff/perm/inh from an array that it will clear not only the defined caps less than CAP_LAST_CAP, but also the higher 28ish bits which are undefined future capabilities. The BSET gets cleared differently. Instead it is cleared one bit at a time. The problem here is that in security/commoncap.c::cap_task_prctl() we actually check the validity of a capability being read. So any task which attempts to 'read all things set in bset' followed by 'unset all things set in bset' will not even attempt to unset the undefined bits higher than CAP_LAST_CAP. So the 'parent' will look something like: CapInh: 0000000000000000 CapPrm: 0000000000000000 CapEff: 0000000000000000 CapBnd: ffffffc000000000 All of this 'should' be fine. Given that these are undefined bits that aren't supposed to have anything to do with permissions. But they do... So lets now consider a task which cleared the eff/perm/inh completely and cleared all of the valid caps in the bset (but not the invalid caps it couldn't read out of the kernel). We know that this is exactly what the libcap-ng library does and what the go capabilities library does. They both leave you in that above situation if you try to clear all of you capapabilities from all 4 sets. If that root task calls execve() the child task will pick up all caps not blocked by the bset. The bset however does not block bits higher than CAP_LAST_CAP. So now the child task has bits in eff which are not in the parent. These are 'meaningless' undefined bits, but still bits which the parent doesn't have. The problem is now in cred_cap_issubset() (or any operation which does a subset test) as the child, while a subset for valid cap bits, is not a subset for invalid cap bits! So now we set durring commit creds that the child is not dumpable. Given it is 'more priv' than its parent. It also means the parent cannot ptrace the child and other stupidity. The solution here: 1) stop hiding capability bits in status This makes debugging easier! 2) stop giving any task undefined capability bits. it's simple, it you don't put those invalid bits in CAP_FULL_SET you won't get them in init and you won't get them in any other task either. This fixes the cap_issubset() tests and resulting fallout (which made the init task in a docker container untraceable among other things) 3) mask out undefined bits when sys_capset() is called as it might use ~0, ~0 to denote 'all capabilities' for backward/forward compatibility. This lets 'capsh --caps="all=eip" -- -c /bin/bash' run. 4) mask out undefined bit when we read a file capability off of disk as again likely all bits are set in the xattr for forward/backward compatibility. This lets 'setcap all+pe /bin/bash; /bin/bash' run Signed-off-by:

commit 97ca0d6c upstream. Commit id 2bd16e3e (spi: omap2-mcspi: Do not configure the controller on each transfer unless needed) does its job too well so omap2_mcspi_setup_transfer() isn't called even when an SPI slave driver changes 'spi->mode'. The result is that the mode requested by the SPI slave driver never takes effect. Fix this by adding the 'mode' member to the omap2_mcspi_cs structure which holds the mode value that the hardware is configured for. When the SPI slave driver changes 'spi->mode' it will be different than the value of this new member and the SPI master driver will know that the hardware must be reconfigured (by calling omap2_mcspi_setup_transfer()).

commit e06871cd upstream. In commit f814f9ac ("spi/orion: add device tree binding"), Device Tree support was added to the spi-orion driver. However, this commit reads the "cell-index" property, without taking into account the fact that DT properties are big-endian encoded. Since most of the platforms using spi-orion with DT have apparently not used anything but cell-index = <0>, the problem was not visible. But as soon as one starts using cell-index = <1>, the problem becomes clearly visible, as the master->bus_num gets a wrong value (actually it gets the value 0, which conflicts with the first bus that has cell-index = <0>). This commit fixes that by using of_property_read_u32() to read the property value, which does the appropriate endianness conversion when needed.

commit 3c4b422a upstream. X-Patchwork-Delegate: mchehab@redhat.com Remove the CONFIG_ prefix from two Kconfig symbols in a dependency for SMS_SIANO_DEBUGFS. This prefix is invalid inside Kconfig files. Note that the current (common sense) dependency on SMS_USB_DRV and SMS_SDIO_DRV being equal ensures that SMS_SIANO_DEBUGFS will not violate its constraints. These constraint are that: - it should only be built if SMS_USB_DRV is set; - it can't be builtin if USB support is modular. So drop the dependency on SMS_USB_DRV, as it is unneeded.

commit 64ea37bb upstream. It seems that there's a bug at au0828 hardware/firmware related to alternate setting: when the device is already at alt 5, a further call causes the URBs to receive -ESHUTDOWN. I found two different encarnations of this issue: 1) at qv4l2, it fails the second time we try to open the video screen; 2) at xawtv, when audio underrun occurs, with is very frequent, at least on my test machine. The fix is simple: just check if alt=5 before calling set_usb_interface(). Signed-off-by:

commit 4c07e328 upstream. The programmed frequency on xc4000 is not the middle frequency, but the initial frequency on the bandwidth range. However, the DVB API works with the middle frequency. This works fine on set_frontend, as the device calculates the needed offset. However, at get_frequency(), the returned value is the initial frequency. That's generally not a big problem on most drivers, however, starting with changeset 6fe1099c, the frequency drift is taken into account at dib7000p driver. This broke support for PCTV 340e, with uses dib7000p demod and xc4000 tuner. Signed-off-by:

commit cc824534 upstream. Looks like MUSB cable removal can cause wake-up interrupts to stop working for device tree based booting at least for UART3 even as nothing is dynamically remuxed. This can be fixed by calling reconfigure_io_chain() for device tree based booting in hwmod code. Note that we already do that for legacy booting if the legacy mux is configured. My guess is that this is related to UART3 and MUSB ULPI hsusb0_data0 and hsusb0_data1 support for Carkit mode that somehow affect the configured IO chain for UART3 and require rearming the wake-up interrupts. In general, for device tree based booting, pinctrl-single calls the rearm hook that in turn calls reconfigure_io_chain so calling reconfigure_io_chain should not be needed from the hwmod code for other events. So let's limit the hwmod rearming of iochain only to HWMOD_FORCE_MSTANDBY where MUSB is currently the only user of it. If we see other devices needing similar changes we can add more checks for it.

commit db9ee220 upstream. It turns out that there are some serious problems with the on-disk format of journal checksum v2. The foremost is that the function to calculate descriptor tag size returns sizes that are too big. This causes alignment issues on some architectures and is compounded by the fact that some parts of jbd2 use the structure size (incorrectly) to determine the presence of a 64bit journal instead of checking the feature flags. Therefore, introduce journal checksum v3, which enlarges the descriptor block tag format to allow for full 32-bit checksums of journal blocks, fix the journal tag function to return the correct sizes, and fix the jbd2 recovery code to use feature flags to determine 64bitness. Add a few function helpers so we don't have to open-code quite so many pieces. Switching to a 16-byte block size was found to increase journal size overhead by a maximum of 0.1%, to convert a 32-bit journal with no checksumming to a 32-bit journal with checksum v3 enabled.
