++ * The UHCI driver uses QHs with Interrupt, Control and Bulk URBs for
++ * automatic queuing. To make it easy to insert entries into the schedule,
++ * we have a skeleton of QHs for each predefined Interrupt latency.
++ * Asynchronous QHs (low-speed control, full-speed control, and bulk)
++ * go onto the period-1 interrupt list, since they all get accessed on
++ * every frame.
++ *
++ * When we want to add a new QH, we add it to the list starting from the
++ * appropriate skeleton QH. For instance, the schedule can look like this:
++ *
++ * skel int128 QH
++ * dev 1 interrupt QH
++ * dev 5 interrupt QH
++ * skel int64 QH
++ * skel int32 QH
++ * ...
++ * skel int1 + async QH
++ * dev 5 low-speed control QH
++ * dev 1 bulk QH
++ * dev 2 bulk QH
++ *
++ * There is a special terminating QH used to keep full-speed bandwidth
++ * reclamation active when no full-speed control or bulk QHs are linked
++ * into the schedule. It has an inactive TD (to work around a PIIX bug,
++ * see the Intel errata) and it points back to itself.
++ *
++ * There's a special skeleton QH for Isochronous QHs which never appears
++ * on the schedule. Isochronous TDs go on the schedule before the
++ * the skeleton QHs. The hardware accesses them directly rather than
++ * through their QH, which is used only for bookkeeping purposes.
++ * While the UHCI spec doesn't forbid the use of QHs for Isochronous,
++ * it doesn't use them either. And the spec says that queues never
++ * advance on an error completion status, which makes them totally
++ * unsuitable for Isochronous transfers.
++ *
++ * There's also a special skeleton QH used for QHs which are in the process
++ * of unlinking and so may still be in use by the hardware. It too never
++ * appears on the schedule.

The ++protocol is implemented over the industry-standard SMBus serial interface and ++enables programming, control, and real-time monitoring of compliant power ++conversion products. This flexible and highly versatile standard allows for ++communication between devices based on both analog and digital technologies, and ++provides true interoperability which will reduce design complexity and shorten ++time to market for power system designers. Pioneered by leading power supply and ++semiconductor companies, this open power system standard is maintained and ++promoted by the PMBus Implementers Forum (PMBus-IF), comprising 30+ adopters ++with the objective to provide support to, and facilitate adoption among, users. ++ ++Unfortunately, while PMBus commands are standardized, there are no mandatory ++commands, and manufacturers can add as many non-standard commands as they like. ++Also, different PMBUs devices act differently if non-supported commands are ++executed. Some devices return an error, some devices return 0xff or 0xffff and ++set a status error flag, and some devices may simply hang up. ++ ++Despite all those difficulties, a generic PMBus device driver is still useful ++and supported since kernel version 2.6.39. However, it was necessary to support ++device specific extensions in addition to the core PMBus driver, since it is ++simply unknown what new device specific functionality PMBus device developers ++come up with next. ++ ++To make device specific extensions as scalable as possible, and to avoid having ++to modify the core PMBus driver repeatedly for new devices, the PMBus driver was ++split into core, generic, and device specific code. The core code (in ++pmbus_core.c) provides generic functionality. The generic code (in pmbus.c) ++provides support for generic PMBus devices. Device specific code is responsible ++for device specific initialization and, if needed, maps device specific ++functionality into generic functionality. This is to some degree comparable ++to PCI code, where generic code is augmented as needed with quirks for all kinds ++of devices. ++ ++PMBus device capabilities auto-detection ++======================================== ++ ++For generic PMBus devices, code in pmbus.c attempts to auto-detect all supported ++PMBus commands. Auto-detection is somewhat limited, since there are simply too ++many variables to consider. For example, it is almost impossible to autodetect ++which PMBus commands are paged and which commands are replicated across all ++pages (see the PMBus specification for details on multi-page PMBus devices). ++ ++For this reason, it often makes sense to provide a device specific driver if not ++all commands can be auto-detected. The data structures in this driver can be ++used to inform the core driver about functionality supported by individual ++chips. ++ ++Some commands are always auto-detected. This applies to all limit commands ++(lcrit, min, max, and crit attributes) as well as associated alarm attributes. ++Limits and alarm attributes are auto-detected because there are simply too many ++possible combinations to provide a manual configuration interface. ++ ++PMBus internal API ++================== ++ ++The API between core and device specific PMBus code is defined in ++drivers/hwmon/pmbus/pmbus.h. In addition to the internal API, pmbus.h defines ++standard PMBus commands and virtual PMBus commands. ++ ++Standard PMBus commands ++----------------------- ++ ++Standard PMBus commands (commands values 0x00 to 0xff) are defined in the PMBUs ++specification. ++ ++Virtual PMBus commands ++---------------------- ++ ++Virtual PMBus commands are provided to enable support for non-standard ++functionality which has been implemented by several chip vendors and is thus ++desirable to support. ++ ++Virtual PMBus commands start with command value 0x100 and can thus easily be ++distinguished from standard PMBus commands (which can not have values larger ++than 0xff). Support for virtual PMBus commands is device specific and thus has ++to be implemented in device specific code. ++ ++Virtual commands are named PMBUS_VIRT_xxx and start with PMBUS_VIRT_BASE. All ++virtual commands are word sized. ++ ++There are currently two types of virtual commands. ++ ++- READ commands are read-only; writes are either ignored or return an error. ++- RESET commands are read/write. Reading reset registers returns zero ++ (used for detection), writing any value causes the associated history to be ++ reset. ++ ++Virtual commands have to be handled in device specific driver code. Chip driver ++code returns non-negative values if a virtual command is supported, or a ++negative error code if not. The chip driver may return -ENODATA or any other ++Linux error code in this case, though an error code other than -ENODATA is ++handled more efficiently and thus preferred. Either case, the calling PMBus ++core code will abort if the chip driver returns an error code when reading ++or writing virtual registers (in other words, the PMBus core code will never ++send a virtual command to a chip). ++ ++PMBus driver information ++------------------------ ++ ++PMBus driver information, defined in struct pmbus_driver_info, is the main means ++for device specific drivers to pass information to the core PMBus driver. ++Specifically, it provides the following information. ++ ++- For devices supporting its data in Direct Data Format, it provides coefficients ++ for converting register values into normalized data. This data is usually ++ provided by chip manufacturers in device datasheets. ++- Supported chip functionality can be provided to the core driver. This may be ++ necessary for chips which react badly if non-supported commands are executed, ++ and/or to speed up device detection and initialization. ++- Several function entry points are provided to support overriding and/or ++ augmenting generic command execution. This functionality can be used to map ++ non-standard PMBus commands to standard commands, or to augment standard ++ command return values with device specific information. ++ ++ API functions ++ ------------- ++ ++ Functions provided by chip driver ++ --------------------------------- ++ ++ All functions return the command return value (read) or zero (write) if ++ successful. A return value of -ENODATA indicates that there is no manufacturer ++ specific command, but that a standard PMBus command may exist. Any other ++ negative return value indicates that the commands does not exist for this ++ chip, and that no attempt should be made to read or write the standard ++ command. ++ ++ As mentioned above, an exception to this rule applies to virtual commands, ++ which _must_ be handled in driver specific code. See "Virtual PMBus Commands" ++ above for more details. ++ ++ Command execution in the core PMBus driver code is as follows. ++ ++ if (chip_access_function) { ++ status = chip_access_function(); ++ if (status != -ENODATA) ++ return status; ++ } ++ if (command >= PMBUS_VIRT_BASE) /* For word commands/registers only */ ++ return -EINVAL; ++ return generic_access(); ++ ++ Chip drivers may provide pointers to the following functions in struct ++ pmbus_driver_info. All functions are optional. ++ ++ int (*read_byte_data)(struct i2c_client *client, int page, int reg); ++ ++ Read byte from page <page>, register <reg>. ++ <page> may be -1, which means "current page". ++ ++ int (*read_word_data)(struct i2c_client *client, int page, int reg); ++ ++ Read word from page <page>, register <reg>. ++ ++ int (*write_word_data)(struct i2c_client *client, int page, int reg, ++ u16 word); ++ ++ Write word to page <page>, register <reg>. ++ ++ int (*write_byte)(struct i2c_client *client, int page, u8 value); ++ ++ Write byte to page <page>, register <reg>. ++ <page> may be -1, which means "current page". ++ ++ int (*identify)(struct i2c_client *client, struct pmbus_driver_info *info); ++ ++ Determine supported PMBus functionality. This function is only necessary ++ if a chip driver supports multiple chips, and the chip functionality is not ++ pre-determined. It is currently only used by the generic pmbus driver ++ (pmbus.c). ++ ++ Functions exported by core driver ++ --------------------------------- ++ ++ Chip drivers are expected to use the following functions to read or write ++ PMBus registers. Chip drivers may also use direct I2C commands. If direct I2C ++ commands are used, the chip driver code must not directly modify the current ++ page, since the selected page is cached in the core driver and the core driver ++ will assume that it is selected.

For such chips, checking the ++status register must be disabled. ++ ++Some i2c controllers do not support single-byte commands (write commands with ++no data, i2c_smbus_write_byte()). With such controllers, clearing the status ++register is impossible, and the PMBUS_SKIP_STATUS_CHECK flag must be set. +diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig +index 71db83f..1869327 100644

778d80be52699596bf70e0eb0761cf5e1e46088d +(ipv6: Add disable_ipv6 sysctl to disable IPv6 operaion on specific interface) +seems to have introduced a leak of sk_buff's for ipv6 traffic, +at least in some configurations where idev is NULL, or when ipv6 +is disabled via sysctl. + +The problem is that if the first condition of the if-statement +returns non-NULL, it returns an skb with only one reference, +and when the other conditions apply, execution jumps to the "out" +label, which does not call kfree_skb for it. + +To plug this leak, change to use the "drop" label instead. +(this relies on it being ok to call kfree_skb on NULL) +This also allows us to avoid calling rcu_read_unlock here, +and removes the only user of the "out" label. + +Signed-off-by: Jesper Nilsson
