The single decimal + prefix number is composed of the 3 lowest bits being the syslog + priority and the higher bits the syslog facility number. + + If no prefix is given, the priority number is the default kernel + log priority and the facility number is set to LOG_USER (1). It + is not possible to inject messages from userspace with the + facility number LOG_KERN (0), to make sure that the origin of + the messages can always be reliably determined. + + Accessing the buffer: + Every read() from the opened device node receives one record + of the kernel's printk buffer. + + The first read() directly following an open() always returns + first message in the buffer; there is no kernel-internal + persistent state; many readers can concurrently open the device + and read from it, without affecting other readers. + + Every read() will receive the next available record. If no more + records are available read() will block, or if O_NONBLOCK is + used -EAGAIN returned. + + Messages in the record ring buffer get overwritten as whole, + there are never partial messages received by read(). + + In case messages get overwritten in the circular buffer while + the device is kept open, the next read() will return -EPIPE, + and the seek position be updated to the next available record. + Subsequent reads() will return available records again. + + Unlike the classic syslog() interface, the 64 bit record + sequence numbers allow to calculate the amount of lost + messages, in case the buffer gets overwritten. And they allow + to reconnect to the buffer and reconstruct the read position + if needed, without limiting the interface to a single reader. + + The device supports seek with the following parameters: + SEEK_SET, 0 + seek to the first entry in the buffer + SEEK_END, 0 + seek after the last entry in the buffer + SEEK_DATA, 0 + seek after the last record available at the time + the last SYSLOG_ACTION_CLEAR was issued. + + The output format consists of a prefix carrying the syslog + prefix including priority and facility, the 64 bit message + sequence number and the monotonic timestamp in microseconds. + The values are separated by a ','. Future extensions might + add more comma separated values before the terminating ';'. + Unknown values should be gracefully ignored. + + The human readable text string starts directly after the ';' + and is terminated by a '\n'.

Overview - -Intel's IXP2000 family of NPUs (IXP2400, IXP2800, IXP2850) is designed -for high-performance network applications such high-availability -telecom systems. In addition to an XScale core, it contains up to 8 -"MicroEngines" that run special code, several high-end networking -interfaces (UTOPIA, SPI, etc), a PCI host bridge, one serial port, -flash interface, and some other odds and ends. For more information, see: - -http://developer.intel.com - -2. Linux Support - -Linux currently supports the following features on the IXP2000 NPUs: - -- On-chip serial -- PCI -- Flash (MTD/JFFS2) -- I2C through GPIO -- Timers (watchdog, OS) - -That is about all we can support under Linux ATM b/c the core networking -components of the chip are accessed via Intel's closed source SDK. -Please contact Intel directly on issues with using those.

In addition, b/c of the way the - Intel SDK is designed, devices are enumerated in a very specific - way. B/c of this this, we use "pci=firmware" option in the kernel - command line so that we do not re-enumerate the bus. - -- IXDP2x01 systems have variable clock tick rates that we cannot determine - via HW registers. The "ixdp2x01_clk=XXX" cmd line options allow you - to pass the clock rate to the board port. - -5.

b/trunk/Documentation/devicetree/bindings/pinctrl/fsl,mxs-pinctrl.txt @@ -0,0 +1,918 @@ +* Freescale MXS Pin Controller + +The pins controlled by mxs pin controller are organized in banks, each bank +has 32 pins. Each pin has 4 multiplexing functions, and generally, the 4th +function is GPIO. The configuration on the pins includes drive strength, +voltage and pull-up. + +Required properties: +- compatible: "fsl,imx23-pinctrl" or "fsl,imx28-pinctrl" +- reg: Should contain the register physical address and length for the + pin controller. + +Please refer to pinctrl-bindings.txt in this directory for details of the +common pinctrl bindings used by client devices. + +The node of mxs pin controller acts as a container for an arbitrary number of +subnodes. Each of these subnodes represents some desired configuration for +a group of pins, and only affects those parameters that are explicitly listed. +In other words, a subnode that describes a drive strength parameter implies no +information about pull-up. For this reason, even seemingly boolean values are +actually tristates in this binding: unspecified, off, or on. Unspecified is +represented as an absent property, and off/on are represented as integer +values 0 and 1. + +Those subnodes under mxs pin controller node will fall into two categories. +One is to set up a group of pins for a function, both mux selection and pin +configurations, and it's called group node in the binding document. The other +one is to adjust the pin configuration for some particular pins that need a +different configuration than what is defined in group node. The binding +document calls this type of node config node. + +On mxs, there is no hardware pin group. The pin group in this binding only +means a group of pins put together for particular peripheral to work in +particular function, like SSP0 functioning as mmc0-8bit. That said, the +group node should include all the pins needed for one function rather than +having these pins defined in several group nodes. It also means each of +"pinctrl-*" phandle in client device node should only have one group node +pointed in there, while the phandle can have multiple config node referenced +there to adjust configurations for some pins in the group. + +Required subnode-properties: +- fsl,pinmux-ids: An integer array. Each integer in the array specify a pin + with given mux function, with bank, pin and mux packed as below. + + [15..12] : bank number + [11..4] : pin number + [3..0] : mux selection + + This integer with mux selection packed is used as an entity by both group + and config nodes to identify a pin. The mux selection in the integer takes + effects only on group node, and will get ignored by driver with config node, + since config node is only meant to set up pin configurations. + + Valid values for these integers are listed below. + +- reg: Should be the index of the group nodes for same function. This property + is required only for group nodes, and should not be present in any config + nodes. + +Optional subnode-properties: +- fsl,drive-strength: Integer. + 0: 4 mA + 1: 8 mA + 2: 12 mA + 3: 16 mA +- fsl,voltage: Integer. + 0: 1.8 V + 1: 3.3 V +- fsl,pull-up: Integer. + 0: Disable the internal pull-up + 1: Enable the internal pull-up + +Examples: + +pinctrl@80018000 { + #address-cells = <1>; + #size-cells = <0>; + compatible = "fsl,imx28-pinctrl"; + reg = <0x80018000 2000>; + + mmc0_8bit_pins_a: mmc0-8bit@0 { + reg = <0>; + fsl,pinmux-ids = < + 0x2000 0x2010 0x2020 0x2030 + 0x2040 0x2050 0x2060 0x2070 + 0x2080 0x2090 0x20a0>; + fsl,drive-strength = <1>; + fsl,voltage = <1>; + fsl,pull-up = <1>; + }; + + mmc_cd_cfg: mmc-cd-cfg { + fsl,pinmux-ids = <0x2090>; + fsl,pull-up = <0>; + }; + + mmc_sck_cfg: mmc-sck-cfg { + fsl,pinmux-ids = <0x20a0>; + fsl,drive-strength = <2>; + fsl,pull-up = <0>; + }; +}; + +In this example, group node mmc0-8bit defines a group of pins for mxs SSP0 +to function as a 8-bit mmc device, with 8mA, 3.3V and pull-up configurations +applied on all these pins. And config nodes mmc-cd-cfg and mmc-sck-cfg are +adjusting the configuration for pins card-detection and clock from what group +node mmc0-8bit defines.

Each pin controller must be represented as a node in device tree, +just like any other hardware module. + +Hardware modules whose signals are affected by pin configuration are +designated client devices. Again, each client device must be represented as a +node in device tree, just like any other hardware module. + +For a client device to operate correctly, certain pin controllers must +set up certain specific pin configurations. Some client devices need a +single static pin configuration, e.g. set up during initialization. Others +need to reconfigure pins at run-time, for example to tri-state pins when the +device is inactive. Hence, each client device can define a set of named +states. The number and names of those states is defined by the client device's +own binding. + +The common pinctrl bindings defined in this file provide an infrastructure +for client device device tree nodes to map those state names to the pin +configuration used by those states. + +Note that pin controllers themselves may also be client devices of themselves. +For example, a pin controller may set up its own "active" state when the +driver loads. This would allow representing a board's static pin configuration +in a single place, rather than splitting it across multiple client device +nodes. The decision to do this or not somewhat rests with the author of +individual board device tree files, and any requirements imposed by the +bindings for the individual client devices in use by that board, i.e. whether +they require certain specific named states for dynamic pin configuration. + +== Pinctrl client devices == + +For each client device individually, every pin state is assigned an integer +ID. These numbers start at 0, and are contiguous. For each state ID, a unique +property exists to define the pin configuration. Each state may also be +assigned a name. When names are used, another property exists to map from +those names to the integer IDs. + +Each client device's own binding determines the set of states the must be +defined in its device tree node, and whether to define the set of state +IDs that must be provided, or whether to define the set of state names that +must be provided. + +Required properties: +pinctrl-0: List of phandles, each pointing at a pin configuration + node. These referenced pin configuration nodes must be child + nodes of the pin controller that they configure. Multiple + entries may exist in this list so that multiple pin + controllers may be configured, or so that a state may be built + from multiple nodes for a single pin controller, each + contributing part of the overall configuration. See the next + section of this document for details of the format of these + pin configuration nodes. + + In some cases, it may be useful to define a state, but for it + to be empty. This may be required when a common IP block is + used in an SoC either without a pin controller, or where the + pin controller does not affect the HW module in question.

It +enables easy writing of HCI-based NFC drivers. The HCI layer runs as an NFC Core +backend, implementing an abstract nfc device and translating NFC Core API +to HCI commands and events. + +HCI +--- + +HCI registers as an nfc device with NFC Core. Requests coming from userspace are +routed through netlink sockets to NFC Core and then to HCI. From this point, +they are translated in a sequence of HCI commands sent to the HCI layer in the +host controller (the chip). The sending context blocks while waiting for the +response to arrive. +HCI events can also be received from the host controller. They will be handled +and a translation will be forwarded to NFC Core as needed. +HCI uses 2 execution contexts: +- one if for executing commands : nfc_hci_msg_tx_work(). Only one command +can be executing at any given moment. +- one if for dispatching received events and responses : nfc_hci_msg_rx_work() + +HCI Session initialization: +--------------------------- + +The Session initialization is an HCI standard which must unfortunately +support proprietary gates. This is the reason why the driver will pass a list +of proprietary gates that must be part of the session. HCI will ensure all +those gates have pipes connected when the hci device is set up. + +HCI Gates and Pipes +------------------- + +A gate defines the 'port' where some service can be found. In order to access +a service, one must create a pipe to that gate and open it. In this +implementation, pipes are totally hidden. The public API only knows gates. +This is consistent with the driver need to send commands to proprietary gates +without knowing the pipe connected to it. + +Driver interface +---------------- + +A driver would normally register itself with HCI and provide the following +entry points: + +struct nfc_hci_ops { + int (*open)(struct nfc_hci_dev *hdev); + void (*close)(struct nfc_hci_dev *hdev); + int (*xmit)(struct nfc_hci_dev *hdev, struct sk_buff *skb); + int (*start_poll)(struct nfc_hci_dev *hdev, u32 protocols); + int (*target_from_gate)(struct nfc_hci_dev *hdev, u8 gate, + struct nfc_target *target); +}; + +open() and close() shall turn the hardware on and off. xmit() shall simply +write a frame to the chip. start_poll() is an optional entrypoint that shall +set the hardware in polling mode. This must be implemented only if the hardware +uses proprietary gates or a mechanism slightly different from the HCI standard. +target_from_gate() is another optional entrypoint to return the protocols +corresponding to a proprietary gate. + +On the rx path, the driver is responsible to push incoming HCP frames to HCI +using nfc_hci_recv_frame(). HCI will take care of re-aggregation and handling +This must be done from a context that can sleep. + +SHDLC +----- + +Most chips use shdlc to ensure integrity and delivery ordering of the HCP +frames between the host controller (the chip) and hosts (entities connected +to the chip, like the cpu). In order to simplify writing the driver, an shdlc +layer is available for use by the driver. +When used, the driver actually registers with shdlc, and shdlc will register +with HCI. HCI sees shdlc as the driver and thus send its HCP frames +through shdlc->xmit. +SHDLC adds a new execution context (nfc_shdlc_sm_work()) to run its state +machine and handle both its rx and tx path. + +Included Drivers +---------------- + +An HCI based driver for an NXP PN544, connected through I2C bus, and using +shdlc is included. + +Execution Contexts +------------------ + +The execution contexts are the following: +- IRQ handler (IRQH): +fast, cannot sleep. stores incoming frames into an shdlc rx queue + +- SHDLC State Machine worker (SMW) +handles shdlc rx & tx queues. Dispatches HCI cmd responses. + +- HCI Tx Cmd worker (MSGTXWQ) +Serialize execution of HCI commands.

Most of the time, this +will be the syscall context. skb will return the result that was received in +the response. + +Internally, execution is asynchronous. So all this API does is to enqueue the +HCI command, setup a local wait queue on stack, and wait_event() for completion. +The wait is not interruptible because it is guaranteed that the command will +complete after some short timeout anyway. + +MSGTXWQ context will then be scheduled and invoke nfc_hci_msg_tx_work(). +This function will dequeue the next pending command and send its HCP fragments +to the lower layer which happens to be shdlc. It will then start a timer to be +able to complete the command with a timeout error if no response arrive. + +SMW context gets scheduled and invokes nfc_shdlc_sm_work(). This function +handles shdlc framing in and out. It uses the driver xmit to send frames and +receives incoming frames in an skb queue filled from the driver IRQ handler. +SHDLC I(nformation) frames payload are HCP fragments. They are agregated to +form complete HCI frames, which can be a response, command, or event. + +HCI Responses are dispatched immediately from this context to unblock +waiting command execution. Reponse processing involves invoking the completion +callback that was provided by nfc_hci_msg_tx_work() when it sent the command. +The completion callback will then wake the syscall context. + +Workflow receiving an HCI event or command +------------------------------------------ + +HCI commands or events are not dispatched from SMW context. Instead, they are +queued to HCI rx_queue and will be dispatched from HCI rx worker +context (MSGRXWQ). This is done this way to allow a cmd or event handler +to also execute other commands (for example, handling the +NFC_HCI_EVT_TARGET_DISCOVERED event from PN544 requires to issue an +ANY_GET_PARAMETER to the reader A gate to get information on the target +that was discovered). + +Typically, such an event will be propagated to NFC Core from MSGRXWQ context. diff --git a/trunk/Documentation/parisc/debugging b/trunk/Documentation/parisc/debugging index d728594058e5..7d75223fa18d 100644 --- a/trunk/Documentation/parisc/debugging +++ b/trunk/Documentation/parisc/debugging @@ -34,6 +34,6 @@ registers interruption handlers read to find out where the machine was interrupted - so if you get an interruption between the instruction that clears the Q bit and the RFI that sets it again you don't know where exactly it happened.

A +certain subset of userland applications benefit by having a reduced set +of available system calls. The resulting set reduces the total kernel +surface exposed to the application. System call filtering is meant for +use with those applications. + +Seccomp filtering provides a means for a process to specify a filter for +incoming system calls. The filter is expressed as a Berkeley Packet +Filter (BPF) program, as with socket filters, except that the data +operated on is related to the system call being made: system call +number and the system call arguments. This allows for expressive +filtering of system calls using a filter program language with a long +history of being exposed to userland and a straightforward data set. + +Additionally, BPF makes it impossible for users of seccomp to fall prey +to time-of-check-time-of-use (TOCTOU) attacks that are common in system +call interposition frameworks. BPF programs may not dereference +pointers which constrains all filters to solely evaluating the system +call arguments directly. + +What it isn't +------------- + +System call filtering isn't a sandbox. It provides a clearly defined +mechanism for minimizing the exposed kernel surface. It is meant to be +a tool for sandbox developers to use. Beyond that, policy for logical +behavior and information flow should be managed with a combination of +other system hardening techniques and, potentially, an LSM of your +choosing. Expressive, dynamic filters provide further options down this +path (avoiding pathological sizes or selecting which of the multiplexed +system calls in socketcall() is allowed, for instance) which could be +construed, incorrectly, as a more complete sandboxing solution. + +Usage +----- + +An additional seccomp mode is added and is enabled using the same +prctl(2) call as the strict seccomp. If the architecture has +CONFIG_HAVE_ARCH_SECCOMP_FILTER, then filters may be added as below: + +PR_SET_SECCOMP: + Now takes an additional argument which specifies a new filter + using a BPF program. + The BPF program will be executed over struct seccomp_data + reflecting the system call number, arguments, and other + metadata. The BPF program must then return one of the + acceptable values to inform the kernel which action should be + taken. + + Usage: + prctl(PR_SET_SECCOMP, SECCOMP_MODE_FILTER, prog); + + The 'prog' argument is a pointer to a struct sock_fprog which + will contain the filter program. If the program is invalid, the + call will return -1 and set errno to EINVAL. + + If fork/clone and execve are allowed by @prog, any child + processes will be constrained to the same filters and system + call ABI as the parent. + + Prior to use, the task must call prctl(PR_SET_NO_NEW_PRIVS, 1) or + run with CAP_SYS_ADMIN privileges in its namespace. If these are not + true, -EACCES will be returned. This requirement ensures that filter + programs cannot be applied to child processes with greater privileges + than the task that installed them. + + Additionally, if prctl(2) is allowed by the attached filter, + additional filters may be layered on which will increase evaluation + time, but allow for further decreasing the attack surface during + execution of a process. + +The above call returns 0 on success and non-zero on error. + +Return values +------------- +A seccomp filter may return any of the following values. If multiple +filters exist, the return value for the evaluation of a given system +call will always use the highest precedent value. (For example, +SECCOMP_RET_KILL will always take precedence.) + +In precedence order, they are: + +SECCOMP_RET_KILL: + Results in the task exiting immediately without executing the + system call. The exit status of the task (status & 0x7f) will + be SIGSYS, not SIGKILL. + +SECCOMP_RET_TRAP: + Results in the kernel sending a SIGSYS signal to the triggering + task without executing the system call. The kernel will + rollback the register state to just before the system call + entry such that a signal handler in the task will be able to + inspect the ucontext_t->uc_mcontext registers and emulate + system call success or failure upon return from the signal + handler. + + The SECCOMP_RET_DATA portion of the return value will be passed + as si_errno. + + SIGSYS triggered by seccomp will have a si_code of SYS_SECCOMP. + +SECCOMP_RET_ERRNO: + Results in the lower 16-bits of the return value being passed + to userland as the errno without executing the system call. + +SECCOMP_RET_TRACE: + When returned, this value will cause the kernel to attempt to + notify a ptrace()-based tracer prior to executing the system + call. If there is no tracer present, -ENOSYS is returned to + userland and the system call is not executed. + + A tracer will be notified if it requests PTRACE_O_TRACESECCOMP + using ptrace(PTRACE_SETOPTIONS). The tracer will be notified + of a PTRACE_EVENT_SECCOMP and the SECCOMP_RET_DATA portion of + the BPF program return value will be available to the tracer + via PTRACE_GETEVENTMSG. + +SECCOMP_RET_ALLOW: + Results in the system call being executed. + +If multiple filters exist, the return value for the evaluation of a +given system call will always use the highest precedent value. + +Precedence is only determined using the SECCOMP_RET_ACTION mask. When +multiple filters return values of the same precedence, only the +SECCOMP_RET_DATA from the most recently installed filter will be +returned. + +Pitfalls +-------- + +The biggest pitfall to avoid during use is filtering on system call +number without checking the architecture value. Why? On any +architecture that supports multiple system call invocation conventions, +the system call numbers may vary based on the specific invocation.

It should work fine on the 64K - adapters, but it will only use one of the 4 banks of RAM. Modifying - this for the 64K version would require a lot of heinous bank - switching, which I'm sure not interested in doing. If you try to - implement a bank switching version, you'll basically have to remember - what bank is enabled and do a switch every time you access a memory - location that's not current. You'll also have to remap pointers on - the driver side, because it only knows about 16K of the memory. - Anyone desperate or masochistic enough to try? - - It seems to be stable now when multiple transmit buffers are used.

In actual fact - * I've always eventually found everything is documented, it just - * requires careful study. - * - * DOC: Theory Of Operation - * - * The 3com 3c527 is a 32bit MCA bus mastering adapter with a large - * amount of on board intelligence that housekeeps a somewhat dumber - * Intel NIC. For performance we want to keep the transmit queue deep - * as the card can transmit packets while fetching others from main - * memory by bus master DMA. Transmission and reception are driven by - * circular buffer queues. - * - * The mailboxes can be used for controlling how the card traverses - * its buffer rings, but are used only for initial setup in this - * implementation. The exec mailbox allows a variety of commands to - * be executed. Each command must complete before the next is - * executed. Primarily we use the exec mailbox for controlling the - * multicast lists. We have to do a certain amount of interesting - * hoop jumping as the multicast list changes can occur in interrupt - * state when the card has an exec command pending. We defer such - * events until the command completion interrupt. - * - * A copy break scheme (taken from 3c59x.c) is employed whereby - * received frames exceeding a configurable length are passed - * directly to the higher networking layers without incuring a copy, - * in what amounts to a time/space trade-off. - * - * The card also keeps a large amount of statistical information - * on-board. In a perfect world, these could be used safely at no - * cost. However, lacking information to the contrary, processing - * them without races would involve so much extra complexity as to - * make it unworthwhile to do so. In the end, a hybrid SW/HW - * implementation was made necessary --- see mc32_update_stats(). - * - * DOC: Notes - * - * It should be possible to use two or more cards, but at this stage - * only by loading two copies of the same module. - * - * The on-board 82586 NIC has trouble receiving multiple - * back-to-back frames and so is likely to drop packets from fast - * senders. -**/ - -#include - -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include - -#include -#include -#include - -#include "3c527.h" - -MODULE_LICENSE("GPL"); - -/* - * The name of the card.

Instead, SYSTIME is defined by a fixed point + * system which allows the user to define the scale counter increment + * value at every level change of the oscillator driving the SYSTIME + * value. For both devices the TIMINCA:IV field defines this + * increment. On the X540 device, 31 bits are provided. However on the + * 82599 only provides 24 bits.

In order to convert the scale counter into + * nanoseconds the cyclecounter and timecounter structures are + * used.
