2017-12-19net: Introduce NETIF_F_GRO_HW.Michael Chan1-0/+9
Introduce NETIF_F_GRO_HW feature flag for NICs that support hardware GRO. With this flag, we can now independently turn on or off hardware GRO when GRO is on. Previously, drivers were using NETIF_F_GRO to control hardware GRO and so it cannot be independently turned on or off without affecting GRO. Hardware GRO (just like GRO) guarantees that packets can be re-segmented by TSO/GSO to reconstruct the original packet stream. Logically, GRO_HW should depend on GRO since it a subset, but we will let individual drivers enforce this dependency as they see fit. Since NETIF_F_GRO is not propagated between upper and lower devices, NETIF_F_GRO_HW should follow suit since it is a subset of GRO. In other words, a lower device can independent have GRO/GRO_HW enabled or disabled and no feature propagation is required. This will preserve the current GRO behavior. This can be changed later if we decide to propagate GRO/ GRO_HW/RXCSUM from upper to lower devices.

2017-12-19media: dvb_frontend: add physical layer scrambling supportAthanasios Oikonomou2-0/+20
This commit adds a new property DTV_SCRAMBLING_SEQUENCE_INDEX. This 18 bit field, when present, carries the index of the DVB-S2 physical layer scrambling sequence as defined in clause 5.5.4 of EN 302 307. There is no explicit signalling method to convey scrambling sequence index to the receiver. If S2 satellite delivery system descriptor is available it can be used to read the scrambling sequence index (EN 300 468 table 41). By default, gold scrambling sequence index 0 is used. The valid scrambling sequence index range is from 0 to 262142. Increase the DVB API version in order userspace to be aware of the changes.

(There are also top-level IRQ indicator registers which are not clear-on-read, but they are not relevant here.) It was quite possible to receive a pending IRQ for, e.g., UART0, enter the threaded IRQ handler, clear the ISR for UART0 which de-asserts the IRQ line, and then race with another event on the same chip, but a different UART channel. That resulted in another edge on the shared-within-the-chip IRQ line which got intercepted by the kernel. That all led to an edge-level interrupt which was not being handled by anybody because our threaded handler hasn't finished yet. As the chip actually uses *level* triggered IRQs, let's convert the example DT bindings to these.

2017-12-19siox: new driver framework for eckelmann SIOXUwe Kleine-König1-0/+87
SIOX is a bus system invented at Eckelmann AG to control their building management and refrigeration systems. Traditionally the bus was implemented on custom microcontrollers, today Linux based machines are in use, too. The topology on a SIOX bus looks as follows: ,------->--DCLK-->---------------+----------------------. ^ v v ,--------. ,----------------------. ,------ | | | ,--------------. | | | |--->--DOUT-->---|->-|shift register|->-|--->---| | | | `--------------' | | | master | | device | | device | | | ,--------------. | | | |---<--DIN---<---|-<-|shift register|-<-|---<---| | | | `--------------' | | `--------' `----------------------' `------ v ^ ^ `----------DLD-------------------+----------------------' There are two control lines (DCLK and DLD) driven from the bus master to all devices in parallel and two daisy chained data lines, one for input and one for output. DCLK is the clock to shift both chains by a single bit. On an edge of DLD the devices latch both their input and output shift registers. This patch adds a framework for this bus type.

2017-12-18media: lirc: when transmitting scancodes, block until transmit is doneSean Young1-2/+2
The semantics for lirc IR transmit with raw IR is that the write call should block until the IR is transmitted. Some drivers have no idea when this actually is (e.g. mceusb), so there is a wait. This is useful for userspace, as it might want to send a IR button press, a gap of a predefined number of milliseconds, and then send a repeat message. It turns out that for transmitting scancodes this feature is even more useful, as user space has no idea how long the IR is. So, maintain the existing semantics for IR scancode transmit.

2017-12-18media: v4l2-dev: convert VFL_TYPE_* into an enumMauro Carvalho Chehab1-5/+12
Using enums makes easier to document, as it can use kernel-doc markups. It also allows cross-referencing, with increases the kAPI readability. Please notice that now cx88_querycap() has to have a default for the VFL type, as there are more types than supported by the driver.

2017-12-18media: v4l2-event.rst: improve events descriptionMauro Carvalho Chehab1-13/+54
Both v4l2-event.rst and v4l2-event.h have an overview of events, but there are some inconsistencies there: - at v4l2-event, the event's ring buffer is called kevent. Its name is, instead, v4l2_kevent; - Some things are mentioned on both places (with different words), others are either on one of the files. In order to cleanup this mess, put everything at v4l2-event.rst and improve it to be a little more coherent and to have cross references.

2017-12-18eeprom: at25: Add DT support for EEPROMs with odd address bitsGeert Uytterhoeven1-1/+3
Certain EEPROMS have a size that is larger than the number of address bytes would allow, and store the MSB of the address in bit 3 of the instruction byte. This can be described in platform data using EE_INSTR_BIT3_IS_ADDR, or in DT using the obsolete legacy "at25,addr-mode" property. But currently there exists no non-deprecated way to describe this in DT. Hence extend the existing "address-width" DT property to allow specifying 9 address bits, and enable support for that in the driver. This has been tested with a Microchip 25LC040A.

2017-12-18ima: support new "hash" and "dont_hash" policy actionsMimi Zohar1-1/+2
The builtin ima_appraise_tcb policy, which is specified on the boot command line, can be replaced with a custom policy, normally early in the boot process. Custom policies can be more restrictive in some ways, like requiring file signatures, but can be less restrictive in other ways, like not appraising mutable files. With a less restrictive policy in place, files in the builtin policy might not be hashed and labeled with a security.ima hash. On reboot, files which should be labeled in the ima_appraise_tcb are not labeled, possibly preventing the system from booting properly. To resolve this problem, this patch extends the existing IMA policy actions "measure", "dont_measure", "appraise", "dont_appraise", and "audit" with "hash" and "dont_hash". The new "hash" action will write the file hash as security.ima, but without requiring the file to be appraised as well. For example, the builtin ima_appraise_tcb policy includes the rule, "appraise fowner=0". Adding the "hash fowner=0" rule to a custom policy, will cause the needed file hashes to be calculated and written as security.ima xattrs.

2017-12-16xtensa: add support for KASANMax Filippov2-1/+7
Cover kernel addresses above 0x90000000 by the shadow map. Enable HAVE_ARCH_KASAN when MMU is enabled. Provide kasan_early_init that fills shadow map with writable copies of kasan_zero_page. Call kasan_early_init right after mmu initialization in the setup_arch. Provide kasan_init that allocates proper shadow map pages from the memblock and puts these pages into the shadow map for addresses from VMALLOC area to the end of KSEG. Call kasan_init right after memblock initialization. Don't use KASAN for the boot code, MMU and KASAN initialization and page fault handler. Make kernel stack size 4 times larger when KASAN is enabled to avoid stack overflows. GCC 7.3, 8 or newer is required to build the xtensa kernel with KASAN.
