Furthermore, the verifier can now mark the +instructions for which zero-ing the upper bits of the destination register +is required, and insert an explicit zero-extension (zext) instruction +(a mov32 variant). This means that for architectures without zext hardware +support, the JIT back-ends do not need to clear the upper bits for +subregisters written by alu32 instructions or narrow loads. Instead, the +back-ends simply need to support code generation for that mov32 variant, +and to overwrite bpf_jit_needs_zext() to make it return "true" (in order to +enable zext insertion in the verifier). + +Note that it is possible for a JIT back-end to have partial hardware +support for zext. In that case, if verifier zext insertion is enabled, +it could lead to the insertion of unnecessary zext instructions. Such +instructions could be removed by creating a simple peephole inside the JIT +back-end: if one instruction has hardware support for zext and if the next +instruction is an explicit zext, then the latter can be skipped when doing +the code generation.

This is a one-digit string, - simply appended to the base phone number - - The internal handling is nearly identical, so replace the appropriate - term to that one, which applies to your local ISDN-environment. - - When the link-level-module isdn.o is loaded, it supports up to 16 - low-level-modules with up to 64 channels. (The number 64 is arbitrarily - chosen and can be configured at compile-time --ISDN_MAX in isdn.h). - A low-level-driver can register itself through an interface (which is - defined in isdnif.h) and gets assigned a slot. - The following char-devices are made available for each channel: - - A raw-control-device with the following functions: - write: raw D-channel-messages (format: depends on driver). - read: raw D-channel-messages (format: depends on driver). - ioctl: depends on driver, i.e. for the ICN-driver, the base-address of - the ports and the shared memory on the card can be set and read - also the boot-code and the protocol software can be loaded into - the card. - - O N L Y !!! for debugging (no locking against other devices): - One raw-data-device with the following functions: - write: data to B-channel. - read: data from B-channel. - - In addition the following devices are made available: - - 128 tty-devices (64 cuix and 64 ttyIx) with integrated modem-emulator: - The functionality is almost the same as that of a serial device - (the line-discs are handled by the kernel), which lets you run - SLIP, CSLIP and asynchronous PPP through the devices. We have tested - Seyon, minicom, CSLIP (uri-dip) PPP, mgetty, XCept and Hylafax. - - The modem-emulation supports the following: - 1.3.1 Commands: - - ATA Answer incoming call. - ATD<No.> Dial, the number may contain: - [0-9] and [,#.*WPT-S] - the latter are ignored until 'S'. - The 'S' must precede the number, if - the line is a SPV (German 1TR6). - ATE0 Echo off. - ATE1 Echo on (default). - ATH Hang-up. - ATH1 Off hook (ignored). - ATH0 Hang-up. - ATI Return "ISDN for Linux...". - ATI0 " - ATI1 " - ATI2 Report of last connection. - ATO On line (data mode). - ATQ0 Enable result codes (default). - ATQ1 Disable result codes (default). - ATSx=y Set register x to y. - ATSx? Show contents of register x. - ATV0 Numeric responses. - ATV1 English responses (default). - ATZ Load registers and EAZ/MSN from Profile. - AT&Bx Set Send-Packet-size to x (max. 4000) - The real packet-size may be limited by the - low-level-driver used. e.g. the HiSax-Module- - limit is 2000. You will get NO Error-Message, - if you set it to higher values, because at the - time of giving this command the corresponding - driver may not be selected (see "Automatic - Assignment") however the size of outgoing packets - will be limited correctly. - AT&D0 Ignore DTR - AT&D2 DTR-low-edge: Hang up and return to - command mode (default). - AT&D3 Same as AT&D2 but also resets all registers. - AT&Ex Set the EAZ/MSN for this channel to x. - AT&F Reset all registers and profile to "factory-defaults" - AT&Lx Set list of phone numbers to listen on. x is a - list of wildcard patterns separated by semicolon. - If this is set, it has precedence over the MSN set - by AT&E. - AT&Rx Select V.110 bitrate adaption. - This command enables V.110 protocol with 9600 baud - (x=9600), 19200 baud (x=19200) or 38400 baud - (x=38400). A value of x=0 disables V.110 switching - back to default X.75. This command sets the following - Registers: - Reg 14 (Layer-2 protocol): - x = 0: 0 - x = 9600: 7 - x = 19200: 8 - x = 38400: 9 - Reg 18.2 = 1 - Reg 19 (Additional Service Indicator): - x = 0: 0 - x = 9600: 197 - x = 19200: 199 - x = 38400: 198 - Note on value in Reg 19: - There is _NO_ common convention for 38400 baud. - The value 198 is chosen arbitrarily. Users - _MUST_ negotiate this value before establishing - a connection. - AT&Sx Set window-size (x = 1..8) (not yet implemented) - AT&V Show all settings. - AT&W0 Write registers and EAZ/MSN to profile. See also - iprofd (5.c in this README). - AT&X0 BTX-mode and T.70-mode off (default) - AT&X1 BTX-mode on. (S13.1=1, S13.5=0 S14=0, S16=7, S18=7, S19=0) - AT&X2 T.70-mode on. (S13.1=1, S13.5=1, S14=0, S16=7, S18=7, S19=0) - AT+Rx Resume a suspended call with CallID x (x = 1,2,3...) - AT+Sx Suspend a call with CallID x (x = 1,2,3...) - - For voice-mode commands refer to README.audio - - 1.3.2 Escape sequence: - During a connection, the emulation reacts just like - a normal modem to the escape sequence <DELAY>+++<DELAY>. - (The escape character - default '+' - can be set in the - register 2). - The DELAY must at least be 1.5 seconds long and delay - between the escape characters must not exceed 0.5 seconds. - - 1.3.3 Registers: - - Nr.

(only for network interfaces if the security flag is set) - contains the caller number in its access list. - 4. Either the channel is not bound exclusively to another Net-interface, or - it is bound AND the other checks apply to exactly this interface. - (For usage of the bind-features, refer to the isdnctrl-man-page) - - Only when a matching interface or tty is found is the call accepted - and the "connection" between the low-level-layer and the link-level-layer - is established and kept until the end of the connection. - In all other cases no connection is established. Isdn4linux can be - configured to either do NOTHING in this case (which is useful, if - other, external devices with the same EAZ/MSN are connected to the bus) - or to reject the call actively. (isdnctrl busreject ...) - - For an outgoing call, the inactive physical lines are searched. - The call is placed on the first physical line, which supports the - requested protocols for the B-channel. If a net-interface, however - is pre-bound to a channel, this channel is used directly. - - This makes it possible to configure several network interfaces and ttys - for one EAZ, if the network interfaces are set to secure operation. - If an incoming call matches one network interface, it gets connected to it. - If another incoming call for the same EAZ arrives, which does not match - a network interface, the first tty gets a "RING" and so on. - -2 System prerequisites: - - ATTENTION! - - Always use the latest module utilities. The current version is - named in Documentation/Changes. Some old versions of insmod - are not capable of setting the driver-Ids correctly. - -3. Lowlevel-driver configuration. - - Configuration depends on how the drivers are built. See the - README.<yourDriver> for information on driver-specific setup. - -4. Device-inodes - - The major and minor numbers and their names are described in - Documentation/admin-guide/devices.rst. The major numbers are: - - 43 for the ISDN-tty's. - 44 for the ISDN-callout-tty's. - 45 for control/info/debug devices. - -5. Application - - a) For some card-types, firmware has to be loaded into the cards, before - proceeding with device-independent setup. See README.<yourDriver> - for how to do that. - - b) If you only intend to use ttys, you are nearly ready now. - - c) If you want to have really permanent "Modem"-settings on disk, you - can start the daemon iprofd. Give it a path to a file at the command- - line. It will store the profile-settings in this file every time - an AT&W0 is performed on any ISDN-tty. If the file already exists, - all profiles are initialized from this file. If you want to unload - any of the modules, kill iprofd first. - - d) For networking, continue: Create an interface: - isdnctrl addif isdn0 - - e) Set the EAZ (or MSN for Euro-ISDN): - isdnctrl eaz isdn0 2 - - (For 1TR6 a single digit is allowed, for Euro-ISDN the number is your - real MSN e.g.: Phone-Number) - - f) Set the number for outgoing calls on the interface: - isdnctrl addphone isdn0 out 1234567 - ... (this can be executed more than once, all assigned numbers are - tried in order) - and the number(s) for incoming calls: - isdnctrl addphone isdn0 in 1234567 - - g) Set the timeout for hang-up: - isdnctrl huptimeout isdn0 <timeout_in_seconds> - - h) additionally you may activate charge-hang-up (= Hang up before - next charge-info, this only works, if your isdn-provider transmits - the charge-info during and after the connection): - isdnctrl chargehup isdn0 on - - i) Set the dial mode of the interface: - isdnctrl dialmode isdn0 auto - "off" means that you (or the system) cannot make any connection - (neither incoming or outgoing connections are possible). Use - this if you want to be sure that no connections will be made. - "auto" means that the interface is in auto-dial mode, and will - attempt to make a connection whenever a network data packet needs - the interface's link. Note that this can cause unexpected dialouts, - and lead to a high phone bill! Some daemons or other pc's that use - this interface can cause this. - Incoming connections are also possible. - "manual" is a dial mode created to prevent the unexpected dialouts. - In this mode, the interface will never make any connections on its - own. You must explicitly initiate a connection with "isdnctrl dial - isdn0". However, after an idle time of no traffic as configured for - the huptimeout value with isdnctrl, the connection _will_ be ended. - If you don't want any automatic hangup, set the huptimeout value to 0. - "manual" is the default. - - j) Setup the interface with ifconfig as usual, and set a route to it. - - k) (optional) If you run X11 and have Tcl/Tk-wish version 4.0, you can use - the script tools/tcltk/isdnmon. You can add actions for line-status - changes. See the comments at the beginning of the script for how to - do that. There are other tty-based tools in the tools-subdirectory - contributed by Michael Knigge (imon), Volker Götz (imontty) and - Andreas Kool (isdnmon). - - l) For initial testing, you can set the verbose-level to 2 (default: 0). - Then all incoming calls are logged, even if they are not addressed - to one of the configured net-interfaces: - isdnctrl verbose 2 - - Now you are ready! A ping to the set address should now result in an - automatic dial-out (look at syslog kernel-messages). - The phone numbers and EAZs can be assigned at any time with isdnctrl. - You can add as many interfaces as you like with addif following the - directions above. Of course, there may be some limitations. But we have - tested as many as 20 interfaces without any problem. However, if you - don't give an interface name to addif, the kernel will assign a name - which starts with "eth". The number of "eth"-interfaces is limited by - the kernel. - -5. Additional options for isdnctrl: - - "isdnctrl secure <InterfaceName> on" - Only incoming calls, for which the caller-id is listed in the access - list of the interface are accepted. You can add caller-id's With the - command "isdnctrl addphone <InterfaceName> in <caller-id>" - Euro-ISDN does not transmit the leading '0' of the caller-id for an - incoming call, therefore you should configure it accordingly. - If the real number for the dialout e.g. is "09311234567" the number - to configure here is "9311234567". The pattern-match function - works similar to the shell mechanism. - - ? one arbitrary digit - * zero or arbitrary many digits - [123] one of the digits in the list - [1-5] one digit between '1' and '5' - a '^' as the first character in a list inverts the list - - - "isdnctrl secure <InterfaceName> off" - Switch off secure operation (default). - - "isdnctrl ihup <InterfaceName> [on|off]" - Switch the hang-up-timer for incoming calls on or off. - - "isdnctrl eaz <InterfaceName>" - Returns the EAZ of an interface. - - "isdnctrl delphone <InterfaceName> in|out <number>" - Deletes a number from one of the access-lists of the interface. - - "isdnctrl delif <InterfaceName>" - Removes the interface (and possible slaves) from the kernel. - (You have to unregister it with "ifconfig <InterfaceName> down" before). - - "isdnctrl callback <InterfaceName> [on|off]" - Switches an interface to callback-mode. In this mode, an incoming call - will be rejected and after this the remote-station will be called. If - you test this feature by using ping, some routers will re-dial very - quickly, so that the callback from isdn4linux may not be recognized. - In this case use ping with the option -i <sec> to increase the interval - between echo-packets. - - "isdnctrl cbdelay <InterfaceName> [seconds]" - Sets the delay (default 5 sec) between an incoming call and start of - dialing when callback is enabled. - - "isdnctrl cbhup <InterfaceName> [on|off]" - This enables (default) or disables an active hangup (reject) when getting an - incoming call for an interface which is configured for callback. - - "isdnctrl encap <InterfaceName> <EncapType>" - Selects the type of packet-encapsulation. The encapsulation can be changed - only while an interface is down. - - At the moment the following values are supported: - - rawip (Default) Selects raw-IP-encapsulation. This means, MAC-headers - are stripped off. - ip IP with type-field. Same as IP but the type-field of the MAC-header - is preserved. - x25iface X.25 interface encapsulation (first byte semantics as defined in - ../networking/x25-iface.txt). Use this for running the linux - X.25 network protocol stack (AF_X25 sockets) on top of isdn. - cisco-h A special-mode for communicating with a Cisco, which is configured - to do "hdlc" - ethernet No stripping. Packets are sent with full MAC-header. - The Ethernet-address of the interface is faked, from its - IP-address: fc:fc:i1:i2:i3:i4, where i1-4 are the IP-addr.-values. - syncppp Synchronous PPP - - uihdlc HDLC with UI-frame-header (for use with DOS ISPA, option -h1) - - - NOTE: x25iface encapsulation is currently experimental. Please - read README.x25 for further details - - - Watching packets, using standard-tcpdump will fail for all encapsulations - except ethernet because tcpdump does not know how to handle packets - without MAC-header. A patch for tcpdump is included in the utility-package - mentioned above. - - "isdnctrl l2_prot <InterfaceName> <L2-ProtocolName>" - Selects a layer-2-protocol. - (With the ICN-driver and the HiSax-driver, "x75i" and "hdlc" is available. - With other drivers, "x75ui", "x75bui", "x25dte", "x25dce" may be - possible too. See README.x25 for x25 related l2 protocols.) - - isdnctrl l3_prot <InterfaceName> <L3-ProtocolName> - The same for layer-3. (At the moment only "trans" is allowed) - - "isdnctrl list <InterfaceName>" - Shows all parameters of an interface and the charge-info. - Try "all" as the interface name. - - "isdnctrl hangup <InterfaceName>" - Forces hangup of an interface. - - "isdnctrl bind <InterfaceName> <DriverId>,<ChannelNumber> [exclusive]" - If you are using more than one ISDN card, it is sometimes necessary to - dial out using a specific card or even preserve a specific channel for - dialout of a specific net-interface. This can be done with the above - command. Replace <DriverId> by whatever you assigned while loading the - module. The <ChannelNumber> is counted from zero. The upper limit - depends on the card used. At the moment no card supports more than - 2 channels, so the upper limit is one. - - "isdnctrl unbind <InterfaceName>" - unbinds a previously bound interface. - - "isdnctrl busreject <DriverId> on|off" - If switched on, isdn4linux replies a REJECT to incoming calls, it - cannot match to any configured interface. - If switched off, nothing happens in this case. - You normally should NOT enable this feature, if the ISDN adapter is not - the only device connected to the S0-bus. Otherwise it could happen that - isdn4linux rejects an incoming call, which belongs to another device on - the bus. - - "isdnctrl addslave <InterfaceName> <SlaveName> - Creates a slave interface for channel-bundling. Slave interfaces are - not seen by the kernel, but their ISDN-part can be configured with - isdnctrl as usual. (Phone numbers, EAZ/MSN, timeouts etc.) If more - than two channels are to be bundled, feel free to create as many as you - want. InterfaceName must be a real interface, NOT a slave. Slave interfaces - start dialing, if the master interface resp. the previous slave interface - has a load of more than 7000 cps. They hangup if the load goes under 7000 - cps, according to their "huptimeout"-parameter. - - "isdnctrl sdelay <InterfaceName> secs." - This sets the minimum time an Interface has to be fully loaded, until - it sends a dial-request to its slave. - - "isdnctrl dial <InterfaceName>" - Forces an interface to start dialing even if no packets are to be - transferred. - - "isdnctrl mapping <DriverId> MSN0,MSN1,MSN2,...MSN9" - This installs a mapping table for EAZ<->MSN-mapping for a single line. - Missing MSN's have to be given as "-" or can be omitted, if at the end - of the commandline. - With this command, it's now possible to have an interface listening to - mixed 1TR6- and Euro-Type lines. In this case, the interface has to be - configured to a 1TR6-type EAZ (one digit). The mapping is also valid - for tty-emulation. Seen from the interface/tty-level the mapping - CAN be used, however it's possible to use single tty's/interfaces with - real MSN's (more digits) also, in which case the mapping will be ignored. - Here is an example: - - You have a 1TR6-type line with base-nr. 1234567 and a Euro-line with - MSN's 987654, 987655 and 987656. The DriverId for the Euro-line is "EURO". - - isdnctrl mapping EURO -,987654,987655,987656,-,987655 - ... - isdnctrl eaz isdn0 1 # listen on 12345671(1tr6) and 987654(euro) - ... - isdnctrl eaz isdn1 4 # listen on 12345674(1tr6) only. - ... - isdnctrl eaz isdn2 987654 # listen on 987654(euro) only. - - Same scheme is used with AT&E... at the tty's. - -6.

It is included in the normal "make [menu]config" target at the -kernel. Don't forget it, especially to select the right D-channel protocol. - -Please note: In older versions of the HiSax driver, all PnP cards -needed to be configured with isapnp and worked only with the HiSax -driver used as a module. - -In the current version, HiSax will automatically use the in-kernel -ISAPnP support, provided you selected it during kernel configuration -(CONFIG_ISAPNP), if you don't give the io=, irq= command line parameters. - -The affected card types are: 4,7,12,14,19,27-30 - -a) when built as a module -------------------------- - -insmod/modprobe hisax.o \ - io=iobase irq=IRQ mem=membase type=card_type \ - protocol=D_channel_protocol id=idstring - -or, if several cards are installed: - -insmod/modprobe hisax.o \ - io=iobase1,iobase2,... irq=IRQ1,IRQ2,... mem=membase1,membase2,... \ - type=card_type1,card_type2,... \ - protocol=D_channel_protocol1,D_channel_protocol2,... \ - id=idstring1%idstring2 ... - -where "iobaseN" represents the I/O base address of the Nth card, "membaseN" -the memory base address of the Nth card, etc. - -The reason for the delimiter "%" being used in the idstrings is that "," -won't work with the current modules package. - -The parameters may be specified in any order. For example, the "io" -parameter may precede the "irq" parameter, or vice versa. If several -cards are installed, the ordering within the comma separated parameter -lists must of course be consistent. - -Only parameters applicable to the card type need to be specified. For -example, the Teles 16.3 card is not memory-mapped, so the "mem" -parameter may be omitted for this card. Sometimes it may be necessary -to specify a dummy parameter, however. This is the case when there is -a card of a different type later in the list that needs a parameter -which the preceding card does not. For instance, if a Teles 16.0 card -is listed after a Teles 16.3 card, a dummy memory base parameter of 0 -must be specified for the 16.3. Instead of a dummy value, the parameter -can also be skipped by simply omitting the value. For example: -mem=,0xd0000.

In this case all incoming calls - with a special (or all) service identifiers are forwarded if the - forwarding reason is met. Activated static services may also be - interrogated (queried). - The i4l diversion services additionally offers a dynamic version of - call forwarding which is not preprogrammed inside the providers exchange - but dynamically activated by i4l. - In this case all incoming calls are checked by rules that may be - compared to the mechanism of ipfwadm or ipchains. If a given rule matches - the checking process is finished and the rule matching will be applied - to the call. - The rules include primary and secondary service identifiers, called - number and subaddress, callers number and subaddress and whether the rule - matches to all filtered calls or only those when all B-channel resources - are exhausted. - Actions that may be invoked by a rule are ignore, proceed, reject, - direct divert or delayed divert of a call. - All incoming calls matching a rule except the ignore rule a reported and - logged as ASCII via the proc filesystem (/proc/net/isdn/divert). If proceed - is selected the call will be held in a proceeding state (without ringing) - for a certain amount of time to let an external program or client decide - how to handle the call. - - -2.

Additionally the i4l services only work together with the HiSax - driver for passive isdn cards.

The static services may not be - used on a point-to-point connection. Further the static services are only - available in some countries (for example germany). Countries requiring the - keypad protocol for activating static diversions (like the netherlands) are - not supported but may use the tty devices for this purpose. - The dynamic diversion services may be used in all countries if the provider - enables the feature CF (call forwarding).

For the x25trace utility to work -you also need to enable "Packet socket". - -For local testing it is also recommended to enable the isdnloop driver -from the isdn subsystem's configuration menu. - -For testing, it is recommended that all isdn drivers and the X.25 PLP -protocol are compiled as loadable modules. Like this, you can recover -from certain errors by simply unloading and reloading the modules. - - - -What's it for? How to use it? -============================= - -X.25 on top of isdn might be useful with two different scenarios: - -- You might want to access a public X.25 data network from your Linux box. - You can use i4l if you were physically connected to the X.25 switch - by an ISDN B-channel (leased line as well as dial up connection should - work). - - This corresponds to ITU-T recommendation X.31 Case A (circuit-mode - access to PSPDN [packet switched public data network]). - - NOTE: X.31 also covers a Case B (access to PSPDN via virtual - circuit / packet mode service). The latter mode (which in theory - also allows using the D-channel) is not supported by isdn4linux. - It should however be possible to establish such packet mode connections - with certain active isdn cards provided that the firmware supports X.31 - and the driver exports this functionality to the user. Currently, - the AVM B1 driver is the only driver which does so. (It should be - possible to access D-channel X.31 with active AVM cards using the - CAPI interface of the AVM-B1 driver). - -- Or you might want to operate certain ISDN teleservices on your linux - box. A lot of those teleservices run on top of the ISO-8208 - (DTE-DTE mode) network layer protocol. ISO-8208 is essentially the - same as ITU-T X.25. - - Popular candidates of such teleservices are EUROfile transfer or any - teleservice applying ITU-T recommendation T.90. - -To use the X.25 protocol on top of isdn, just create an isdn network -interface as usual, configure your own and/or peer's ISDN numbers, -and choose x25iface encapsulation by - - isdnctrl encap <iface-name> x25iface. - -Once encap is set like this, the device can be used by the X.25 packet layer. - -All the stuff needed for X.25 is implemented inside the isdn link -level (mainly isdn_net.c and some new source files). Thus, it should -work with every existing HL driver. I was able to successfully open X.25 -connections on top of the isdnloop driver and the hisax driver. -"x25iface"-encapsulation bypasses demand dialing. Dialing will be -initiated when the upper (X.25 packet) layer requests the lapb datalink to -be established. But hangup timeout is still active. Whenever a hangup -occurs, all existing X.25 connections on that link will be cleared -It is recommended to use sufficiently large hangup-timeouts for the -isdn interfaces. - - -In order to set up a conforming protocol stack you also need to -specify the proper l2_prot parameter: - -To operate in ISO-8208 X.25 DTE-DTE mode, use - - isdnctrl l2_prot <iface-name> x75i - -To access an X.25 network switch via isdn (your linux box is the DTE), use - - isdnctrl l2_prot <iface-name> x25dte - -To mimic an X.25 network switch (DCE side of the connection), use - - isdnctrl l2_prot <iface-name> x25dce - -However, x25dte or x25dce is currently not supported by any real HL -level driver. The main difference between x75i and x25dte/dce is that -x25d[tc]e uses fixed lap_b addresses. With x75i, the side which -initiates the isdn connection uses the DTE's lap_b address while the -called side used the DCE's lap_b address. Thus, l2_prot x75i might -probably work if you access a public X.25 network as long as the -corresponding isdn connection is set up by you. At least one test -was successful to connect via isdn4linux to an X.25 switch using this -trick. At the switch side, a terminal adapter X.21 was used to connect -it to the isdn. - - -How to set up a test installation? -================================== - -To test X.25 on top of isdn, you need to get - -- a recent version of the "isdnctrl" program that supports setting the new - X.25 specific parameters. - -- the x25-utils-2.X package from - ftp://ftp.hes.iki.fi/pub/ham/linux/ax25/x25utils-* - (don't confuse the x25-utils with the ax25-utils) - -- an application program that uses linux PF_X25 sockets (some are - contained in the x25-util package). - -Before compiling the user level utilities make sure that the compiler/ -preprocessor will fetch the proper kernel header files of this kernel -source tree. Either make /usr/include/linux a symbolic link pointing to -this kernel's include/linux directory or set the appropriate compiler flags. - -When all drivers and interfaces are loaded and configured you need to -ifconfig the network interfaces up and add X.25-routes to them. Use -the usual ifconfig tool. - -ifconfig <iface-name> up - -But a special x25route tool (distributed with the x25-util package) -is needed to set up X.25 routes. I.e. - -x25route add 01 <iface-name> - -will cause all x.25 connections to the destination X.25-address -"01" to be routed to your created isdn network interface. - -There are currently no real X.25 applications available. However, for -tests, the x25-utils package contains a modified version of telnet -and telnetd that uses X.25 sockets instead of tcp/ip sockets. You can -use those for your first tests. Furthermore, you might check -ftp://ftp.hamburg.pop.de/pub/LOCAL/linux/i4l-eft/ which contains some -alpha-test implementation ("eftp4linux") of the EUROfile transfer -protocol. - -The scripts distributed with the eftp4linux test releases might also -provide useful examples for setting up X.25 on top of isdn. - -The x25-utility package also contains an x25trace tool that can be -used to monitor X.25 packets received by the network interfaces. -The /proc/net/x25* files also contain useful information. - -- Henner diff --git a/Documentation/isdn/syncPPP.FAQ b/Documentation/isdn/syncPPP.FAQ deleted file mode 100644 index 3257a4bc0786..000000000000 --- a/Documentation/isdn/syncPPP.FAQ +++ /dev/null @@ -1,224 +0,0 @@ -simple isdn4linux PPP FAQ .. to be continued .. not 'debugged' -------------------------------------------------------------------- - -Q01: what's pppd, ipppd, syncPPP, asyncPPP ?? -Q02: error message "this system lacks PPP support" -Q03: strange information using 'ifconfig' -Q04: MPPP??

(e.g when - using ttyI* or tty* devices) - - The ipppd handles PPP packets coming in HDLC - frames (bit based protocol) ... The PPP driver - in isdn4linux pushes all IP packets direct - to the network layer and all PPP protocol - frames to the /dev/ippp* device. - So, the ipppd is a simple external network - protocol handler. - - If you login into a remote machine using the - /dev/ttyI* devices and then enable PPP on the - remote terminal server -> use the 'old' pppd - - If your remote side immediately starts to send - frames ... you probably connect to a - syncPPP machine .. use the network device part - of isdn4linux with the 'syncppp' encapsulation - and make sure, that the ipppd is running and - connected to at least one /dev/ippp*. Check the - isdn4linux manual on how to configure a network device. - --- - -Q02: when I start the ipppd .. I only get the - error message "this system lacks PPP support" -A: check that at least the device 'ippp0' exists. - (you can check this e.g with the program 'ifconfig') - The ipppd NEEDS this device under THIS name .. - If this device doesn't exists, use: - isdnctrl addif ippp0 - isdnctrl encap ippp0 syncppp - ...

What's that and how can I use it ... - -A: MPPP or MP or MPP (Warning: MP is also an - acronym for 'Multi Processor') stands for - Multi Point to Point and means bundling - of several channels to one logical stream. - To enable MPPP negotiation you must call the - ipppd with the '+mp' option. - You must also configure a slave device for - every additional channel. (see the i4l manual - for more) - To use channel bundling you must first activate - the 'master' or initial call. Now you can add - the slave channels with the command: - isdnctrl addlink <device> - e.g: - isdnctrl addlink ippp0 - This is different from other encapsulations of - isdn4linux! With syncPPP, there is no automatic - activation of slave devices. - --- - -Q05: I tried MPPP but it doesn't work .. the ipppd - writes in the debug log something like: - .. rcvd [0][proto=0x3d] c0 00 00 00 80 fd 01 01 00 0a ... - .. sent [0][LCP ProtRej id=0x2 00 3d c0 00 00 00 80 fd 01 ... - -A: you forgot to compile MPPP/RFC1717 support into the - ISDN Subsystem. Recompile with this option enabled. - --- - -Q06: can I use asynchronous PPP encapsulation - over the network interface of isdn4linux .. - -A: No .. that's not possible .. Use the standard - PPP package over the /dev/ttyI* devices. You - must not use the ipppd for this. - --- - -Q07: A SunISDN machine tries to connect my i4l system, - which doesn't work. - Checking the debug log I just saw garbage like: -!![ ... fill in the line ... ]!! - -A: The Sun tries to talk asynchronous PPP ... i4l - can't understand this ... try to use the ttyI* - devices with the standard PPP/pppd package - -A: (from Alexanter Strauss: ) -!![ ... fill in mail ]!! - --- - -Q08: I wanna talk to remote machines, which need - a different configuration. The only way - I found to do this is to kill the ipppd and - start a new one with another config to connect - to the second machine. - -A: you must bind a network interface explicitly to - an ippp device, where you can connect a (for this - interface) individually configured ipppd. - --- - -Q09: When I start the ipppd I only get error messages - from the i4l driver .. - -A: When starting, the ipppd calls functions which may - trigger a network packet. (e.g gethostbyname()). - Without the ipppd (at this moment, it is not - fully started) we can't handle this network request. - Try to configure hostnames necessary for the ipppd - in your local /etc/hosts file or in a way, that - your system can resolve it without using an - isdn/ippp network-interface. - --- - -Q10: I wanna use dynamic IP address assignment ... How - must I configure the network device. - -A: At least you must have a route which forwards - a packet to the ippp network-interface to trigger - the dial-on-demand. - A default route to the ippp-interface will work. - Now you must choose a dummy IP address for your - interface. - If for some reason you can't set the default - route to the ippp interface, you may take any - address of the subnet from which you expect your - dynamic IP number and set a 'network route' for - this subnet to the ippp interface. - To allow overriding of the dummy address you - must call the ipppd with the 'ipcp-accept-local' option. - -A: You must know, how the ipppd gets the addresses it wanna - configure. If you don't give any option, the ipppd - tries to negotiate the local host address! - With the option 'noipdefault' it requests an address - from the remote machine. With 'useifip' it gets the - addresses from the net interface. Or you set the address - on the option line with the <a.b.c.d:e.f.g.h> option. - Note: the IP address of the remote machine must be configured - locally or the remote machine must send it in an IPCP request. - If your side doesn't know the IP address after negotiation, it - closes the connection! - You must allow overriding of address with the 'ipcp-accept-*' - options, if you have set your own or the remote address - explicitly. - -A: Maybe you try these options .. e.g: - - /sbin/ipppd :$REMOTE noipdefault /dev/ippp0 - - where REMOTE must be the address of the remote machine (the - machine, which gives you your address) - --- - -Q11: I can't connect. How can I check where the problem is. - -A: A good help log is the debug output from the ipppd... - Check whether you can find there: - - only a few LCP-conf-req SENT messages (less then 10) - and then a Term-REQ: - -> check whether your ISDN card is well configured - it seems, that your machine doesn't dial - (IRQ,IO,Proto, etc problems) - Configure your ISDN card to print debug messages and - check the /dev/isdnctrl output next time. There - you can see, whether there is activity on the card/line. - - there are at least a few RECV messages in the log: - -> fine: your card is dialing and your remote machine - tries to talk with you. Maybe only a missing - authentication. Check your ipppd configuration again. - - the ipppd exits for some reason: - -> not good ... check /var/adm/syslog and /var/adm/daemon. - Could be a bug in the ipppd. - --- - -Q12: How can I reduce login delay? - -A: Log a login session ('debug' log) and check which options - your remote side rejects. Next time configure your ipppd - to not negotiate these options. Another 'side effect' is, that - this increases redundancy.

To disable RSS for UDP the + RX Flow L3/L4 rule may be used. + + Example: + ethtool -N eth0 flow-type udp4 action 0 loc 32 + +Command Line Parameters +======================= +The following command line parameters are available on atlantic driver: + +aq_itr -Interrupt throttling mode +---------------------------------------- +Accepted values: 0, 1, 0xFFFF +Default value: 0xFFFF +0 - Disable interrupt throttling. +1 - Enable interrupt throttling and use specified tx and rx rates. +0xFFFF - Auto throttling mode. Driver will choose the best RX and TX + interrupt throtting settings based on link speed. + +aq_itr_tx - TX interrupt throttle rate +---------------------------------------- +Accepted values: 0 - 0x1FF +Default value: 0 +TX side throttling in microseconds. Adapter will setup maximum interrupt delay +to this value. Minimum interrupt delay will be a half of this value + +aq_itr_rx - RX interrupt throttle rate +---------------------------------------- +Accepted values: 0 - 0x1FF +Default value: 0 +RX side throttling in microseconds. Adapter will setup maximum interrupt delay +to this value. Minimum interrupt delay will be a half of this value + +Note: ITR settings could be changed in runtime by ethtool -c means (see below) + +Config file parameters +======================= +For some fine tuning and performance optimizations, +some parameters can be changed in the {source_dir}/aq_cfg.h file. + +AQ_CFG_RX_PAGEORDER +---------------------------------------- +Default value: 0 +RX page order override. Thats a power of 2 number of RX pages allocated for +each descriptor. Received descriptor size is still limited by AQ_CFG_RX_FRAME_MAX. +Increasing pageorder makes page reuse better (actual on iommu enabled systems). + +AQ_CFG_RX_REFILL_THRES +---------------------------------------- +Default value: 32 +RX refill threshold. RX path will not refill freed descriptors until the +specified number of free descriptors is observed. Larger values may help +better page reuse but may lead to packet drops as well. + +AQ_CFG_VECS_DEF +------------------------------------------------------------ +Number of queues +Valid Range: 0 - 8 (up to AQ_CFG_VECS_MAX) +Default value: 8 +Notice this value will be capped by the number of cores available on the system. + +AQ_CFG_IS_RSS_DEF +------------------------------------------------------------ +Enable/disable Receive Side Scaling + +This feature allows the adapter to distribute receive processing +across multiple CPU-cores and to prevent from overloading a single CPU core. + +Valid values +0 - disabled +1 - enabled + +Default value: 1 + +AQ_CFG_NUM_RSS_QUEUES_DEF +------------------------------------------------------------ +Number of queues for Receive Side Scaling +Valid Range: 0 - 8 (up to AQ_CFG_VECS_DEF) + +Default value: AQ_CFG_VECS_DEF + +AQ_CFG_IS_LRO_DEF +------------------------------------------------------------ +Enable/disable Large Receive Offload + +This offload enables the adapter to coalesce multiple TCP segments and indicate +them as a single coalesced unit to the OS networking subsystem. +The system consumes less energy but it also introduces more latency in packets processing. + +Valid values +0 - disabled +1 - enabled + +Default value: 1 + +AQ_CFG_TX_CLEAN_BUDGET +---------------------------------------- +Maximum descriptors to cleanup on TX at once. +Default value: 256 + +After the aq_cfg.h file changed the driver must be rebuilt to take effect. + +Support +======= + +If an issue is identified with the released source code on the supported +kernel with a supported adapter, email the specific information related +to the issue to support@aquantia.com + +License +======= + +aQuantia Corporation Network Driver +Copyright(c) 2014 - 2019 aQuantia Corporation. + +This program is free software; you can redistribute it and/or modify it +under the terms and conditions of the GNU General Public License, +version 2, as published by the Free Software Foundation. diff --git a/Documentation/networking/device_drivers/google/gve.rst b/Documentation/networking/device_drivers/google/gve.rst new file mode 100644 index 000000000000..793693cef6e3 --- /dev/null +++ b/Documentation/networking/device_drivers/google/gve.rst @@ -0,0 +1,123 @@ +..
