If that happens in a script, deviating from -the old syntax in output has a high chance of breaking it. - -Therefore revert Florian's patch changing inversion character position -in output and review the old code for consistency - the only thing -changed on top of the actual revert is ebtables' own copy of -print_iface() to make it adhere to the intrapositioned negation scheme -used throughout ebtables. - -Added extension tests by the reverted commit have been kept. - -Signed-off-by: Phil Sutter -Signed-off-by: Florian Westphal -(cherry picked from commit 35b22e82fa62e10950d8e0fa53a755d4abadf346) -Signed-off-by: Phil Sutter ---- - extensions/libebt_802_3.c | 4 ++-- - extensions/libebt_802_3.t | 2 +- - extensions/libebt_arp.c | 14 +++++++------- - extensions/libebt_arp.t | 8 ++++---- - extensions/libebt_ip.c | 16 ++++++++-------- - extensions/libebt_ip.t | 6 +++--- - extensions/libebt_ip6.c | 14 +++++++------- - extensions/libebt_ip6.t | 6 +++--- - extensions/libebt_mark_m.c | 2 +- - extensions/libebt_mark_m.t | 4 ++-- - extensions/libebt_pkttype.c | 5 +---- - extensions/libebt_pkttype.t | 13 +++++++------ - extensions/libebt_standard.t | 4 ++-- - extensions/libebt_stp.c | 5 ++--- - extensions/libebt_vlan.c | 13 ++++--------- - extensions/libebt_vlan.t | 10 +++++----- - iptables/nft-bridge.c | 6 +++--- - 17 files changed, 62 insertions(+), 70 deletions(-) - -diff --git a/extensions/libebt_802_3.c b/extensions/libebt_802_3.c -index 9e91d05262591..f05d02ead5a4a 100644 ---- a/extensions/libebt_802_3.c -+++ b/extensions/libebt_802_3.c -@@ -98,15 +98,15 @@ static void br802_3_print(const void *ip, const struct xt_entry_match *match, - struct ebt_802_3_info *info = (struct ebt_802_3_info *)match->data; - - if (info->bitmask & EBT_802_3_SAP) { -+ printf("--802_3-sap "); - if (info->invflags & EBT_802_3_SAP) - printf("!

These rules inspect -the ARP frames which they see. -.B arptables -is analogous to the -.B iptables -user space tool, but -.B arptables -is less complicated. - -.SS CHAINS -The kernel table is used to divide functionality into -different sets of rules. Each set of rules is called a chain. -Each chain is an ordered list of rules that can match ARP frames. If a -rule matches an ARP frame, then a processing specification tells -what to do with that matching frame. The processing specification is -called a 'target'. However, if the frame does not match the current -rule in the chain, then the next rule in the chain is examined and so forth. -The user can create new (user-defined) chains which can be used as the 'target' of a rule. - -.SS TARGETS -A firewall rule specifies criteria for an ARP frame and a frame -processing specification called a target. When a frame matches a rule, -then the next action performed by the kernel is specified by the target. -The target can be one of these values: -.IR ACCEPT , -.IR DROP , -.IR CONTINUE , -.IR RETURN , -an 'extension' (see below) or a user-defined chain. -.PP -.I ACCEPT -means to let the frame through. -.I DROP -means the frame has to be dropped. -.I CONTINUE -means the next rule has to be checked. This can be handy to know how many -frames pass a certain point in the chain or to log those frames. -.I RETURN -means stop traversing this chain and resume at the next rule in the -previous (calling) chain. -For the extension targets please see the -.B "TARGET EXTENSIONS" -section of this man page. -.SS TABLES -There is only one ARP table in the Linux -kernel. The table is -.BR filter. -You can drop the '-t filter' argument to the arptables command. -The -t argument must be the -first argument on the arptables command line, if used. -.TP -.B "-t, --table" -.br -.BR filter , -is the only table and contains two built-in chains: -.B INPUT -(for frames destined for the host) and -.B OUTPUT -(for locally-generated frames). -.br -.br -.SH ARPTABLES COMMAND LINE ARGUMENTS -After the initial arptables command line argument, the remaining -arguments can be divided into several different groups. These groups -are commands, miscellaneous commands, rule-specifications, match-extensions, -and watcher-extensions. -.SS COMMANDS -The arptables command arguments specify the actions to perform on the table -defined with the -t argument. If you do not use the -t argument to name -a table, the commands apply to the default filter table. -With the exception of the -.B "-Z" -command, only one command may be used on the command line at a time. -.TP -.B "-A, --append" -Append a rule to the end of the selected chain. -.TP -.B "-D, --delete" -Delete the specified rule from the selected chain. There are two ways to -use this command. The first is by specifying an interval of rule numbers -to delete, syntax: start_nr[:end_nr]. Using negative numbers is allowed, for more -details about using negative numbers, see the -I command. The second usage is by -specifying the complete rule as it would have been specified when it was added. -.TP -.B "-I, --insert" -Insert the specified rule into the selected chain at the specified rule number. -If the current number of rules equals N, then the specified number can be -between -N and N+1. For a positive number i, it holds that i and i-N-1 specify the -same place in the chain where the rule should be inserted. The number 0 specifies -the place past the last rule in the chain and using this number is therefore -equivalent with using the -A command. -.TP -.B "-R, --replace" -Replaces the specified rule into the selected chain at the specified rule number. -If the current number of rules equals N, then the specified number can be -between 1 and N. i specifies the place in the chain where the rule should be replaced. -.TP -.B "-P, --policy" -Set the policy for the chain to the given target. The policy can be -.BR ACCEPT ", " DROP " or " RETURN . -.TP -.B "-F, --flush" -Flush the selected chain. If no chain is selected, then every chain will be -flushed. Flushing the chain does not change the policy of the -chain, however. -.TP -.B "-Z, --zero" -Set the counters of the selected chain to zero. If no chain is selected, all the counters -are set to zero. The -.B "-Z" -command can be used in conjunction with the -.B "-L" -command. -When both the -.B "-Z" -and -.B "-L" -commands are used together in this way, the rule counters are printed on the screen -before they are set to zero. -.TP -.B "-L, --list" -List all rules in the selected chain. If no chain is selected, all chains -are listed. -.TP -.B "-N, --new-chain" -Create a new user-defined chain with the given name. The number of -user-defined chains is unlimited. A user-defined chain name has maximum -length of 31 characters. -.TP -.B "-X, --delete-chain" -Delete the specified user-defined chain. There must be no remaining references -to the specified chain, otherwise -.B arptables -will refuse to delete it. If no chain is specified, all user-defined -chains that aren't referenced will be removed. -.TP -.B "-E, --rename-chain" -Rename the specified chain to a new name. Besides renaming a user-defined -chain, you may rename a standard chain name to a name that suits your -taste. For example, if you like PREBRIDGING more than PREROUTING, -then you can use the -E command to rename the PREROUTING chain. If you do -rename one of the standard -.B arptables -chain names, please be sure to mention -this fact should you post a question on the -.B arptables -mailing lists. -It would be wise to use the standard name in your post. Renaming a standard -.B arptables -chain in this fashion has no effect on the structure or function -of the -.B arptables -kernel table. - -.SS MISCELLANOUS COMMANDS -.TP -.B "-V, --version" -Show the version of the arptables userspace program. -.TP -.B "-h, --help" -Give a brief description of the command syntax. -.TP -.BR "-j, --jump " "\fItarget\fP" -The target of the rule. This is one of the following values: -.BR ACCEPT , -.BR DROP , -.BR CONTINUE , -.BR RETURN , -a target extension (see -.BR "TARGET EXTENSIONS" ")" -or a user-defined chain name. -.TP -.BI "-c, --set-counters " "PKTS BYTES" -This enables the administrator to initialize the packet and byte -counters of a rule (during -.B INSERT, -.B APPEND, -.B REPLACE -operations). - -.SS RULE-SPECIFICATIONS -The following command line arguments make up a rule specification (as used -in the add and delete commands). A "!" option before the specification -inverts the test for that specification. Apart from these standard rule -specifications there are some other command line arguments of interest. -.TP -.BR "-s, --source-ip " "[!] \fIaddress\fP[/\fImask]\fP" -The Source IP specification. -.TP -.BR "-d, --destination-ip " "[!] \fIaddress\fP[/\fImask]\fP" -The Destination IP specification. -.TP -.BR "--source-mac " "[!] \fIaddress\fP[/\fImask\fP]" -The source mac address.

These tables are used to divide functionality into -different sets of rules. Each set of rules is called a chain. -Each chain is an ordered list of rules that can match Ethernet frames. If a -rule matches an Ethernet frame, then a processing specification tells -what to do with that matching frame. The processing specification is -called a 'target'. However, if the frame does not match the current -rule in the chain, then the next rule in the chain is examined and so forth. -The user can create new (user-defined) chains that can be used as the 'target' -of a rule. User-defined chains are very useful to get better performance -over the linear traversal of the rules and are also essential for structuring -the filtering rules into well-organized and maintainable sets of rules. -.SS TARGETS -A firewall rule specifies criteria for an Ethernet frame and a frame -processing specification called a target. When a frame matches a rule, -then the next action performed by the kernel is specified by the target. -The target can be one of these values: -.BR ACCEPT , -.BR DROP , -.BR CONTINUE , -.BR RETURN , -an 'extension' (see below) or a jump to a user-defined chain. -.PP -.B ACCEPT -means to let the frame through. -.B DROP -means the frame has to be dropped. -.B CONTINUE -means the next rule has to be checked. This can be handy, f.e., to know how many -frames pass a certain point in the chain, to log those frames or to apply multiple -targets on a frame. -.B RETURN -means stop traversing this chain and resume at the next rule in the -previous (calling) chain. -For the extension targets please refer to the -.B "TARGET EXTENSIONS" -section of this man page. -.SS TABLES -As stated earlier, there are two ebtables-nft tables in the Linux -kernel. The table names are -.BR filter " and " nat . -Of these two tables, -the filter table is the default table that the command operates on. -If you are working with the filter table, then you can drop the '-t filter' -argument to the ebtables command. However, you will need to provide -the -t argument for -.B nat -table. Moreover, the -t argument must be the -first argument on the ebtables command line, if used. -.TP -.B "-t, --table" -.br -.B filter -is the default table and contains three built-in chains: -.B INPUT -(for frames destined for the bridge itself, on the level of the MAC destination address), -.B OUTPUT -(for locally-generated or (b)routed frames) and -.B FORWARD -(for frames being forwarded by the bridge). -.br -.br -.B nat -is mostly used to change the mac addresses and contains three built-in chains: -.B PREROUTING -(for altering frames as soon as they come in), -.B OUTPUT -(for altering locally generated or (b)routed frames before they are bridged) and -.B POSTROUTING -(for altering frames as they are about to go out). A small note on the naming -of chains PREROUTING and POSTROUTING: it would be more accurate to call them -PREFORWARDING and POSTFORWARDING, but for all those who come from the -iptables world to ebtables it is easier to have the same names. Note that you -can change the name -.BR "" ( -E ) -if you don't like the default. -.SH EBTABLES COMMAND LINE ARGUMENTS -After the initial ebtables '-t table' command line argument, the remaining -arguments can be divided into several groups. These groups -are commands, miscellaneous commands, rule specifications, match extensions, -watcher extensions and target extensions. -.SS COMMANDS -The ebtables command arguments specify the actions to perform on the table -defined with the -t argument. If you do not use the -t argument to name -a table, the commands apply to the default filter table. -Only one command may be used on the command line at a time, except when -the commands -.BR -L " and " -Z -are combined, the commands -.BR -N " and " -P -are combined, or when -.B --atomic-file -is used. -.TP -.B "-A, --append" -Append a rule to the end of the selected chain. -.TP -.B "-D, --delete" -Delete the specified rule or rules from the selected chain. There are two ways to -use this command. The first is by specifying an interval of rule numbers -to delete (directly after -.BR -D ). -Syntax: \fIstart_nr\fP[\fI:end_nr\fP] (use -.B -L --Ln -to list the rules with their rule number). When \fIend_nr\fP is omitted, all rules starting -from \fIstart_nr\fP are deleted. Using negative numbers is allowed, for more -details about using negative numbers, see the -.B -I -command. The second usage is by -specifying the complete rule as it would have been specified when it was added. Only -the first encountered rule that is the same as this specified rule, in other -words the matching rule with the lowest (positive) rule number, is deleted. -.TP -.B "-C, --change-counters" -Change the counters of the specified rule or rules from the selected chain. There are two ways to -use this command. The first is by specifying an interval of rule numbers -to do the changes on (directly after -.BR -C ). -Syntax: \fIstart_nr\fP[\fI:end_nr\fP] (use -.B -L --Ln -to list the rules with their rule number). The details are the same as for the -.BR -D " command. The second usage is by" -specifying the complete rule as it would have been specified when it was added. Only -the counters of the first encountered rule that is the same as this specified rule, in other -words the matching rule with the lowest (positive) rule number, are changed. -In the first usage, the counters are specified directly after the interval specification, -in the second usage directly after -.BR -C . -First the packet counter is specified, then the byte counter. If the specified counters start -with a '+', the counter values are added to the respective current counter values. -If the specified counters start with a '-', the counter values are decreased from the respective -current counter values. No bounds checking is done. If the counters don't start with '+' or '-', -the current counters are changed to the specified counters. -.TP -.B "-I, --insert" -Insert the specified rule into the selected chain at the specified rule number. If the -rule number is not specified, the rule is added at the head of the chain. -If the current number of rules equals -.IR N , -then the specified number can be -between -.IR -N " and " N+1 . -For a positive number -.IR i , -it holds that -.IR i " and " i-N-1 -specify the same place in the chain where the rule should be inserted. The rule number -0 specifies the place past the last rule in the chain and using this number is therefore -equivalent to using the -.BR -A " command." -Rule numbers structly smaller than 0 can be useful when more than one rule needs to be inserted -in a chain. -.TP -.B "-P, --policy" -Set the policy for the chain to the given target. The policy can be -.BR ACCEPT ", " DROP " or " RETURN . -.TP -.B "-F, --flush" -Flush the selected chain. If no chain is selected, then every chain will be -flushed. Flushing a chain does not change the policy of the -chain, however. -.TP -.B "-Z, --zero" -Set the counters of the selected chain to zero. If no chain is selected, all the counters -are set to zero. The -.B "-Z" -command can be used in conjunction with the -.B "-L" -command. -When both the -.B "-Z" -and -.B "-L" -commands are used together in this way, the rule counters are printed on the screen -before they are set to zero. -.TP -.B "-L, --list" -List all rules in the selected chain. If no chain is selected, all chains -are listed. -.br -The following options change the output of the -.B "-L" -command. -.br -.B "--Ln" -.br -Places the rule number in front of every rule. This option is incompatible with the -.BR --Lx " option." -.br -.B "--Lc" -.br -Shows the counters at the end of each rule displayed by the -.B "-L" -command. Both a frame counter (pcnt) and a byte counter (bcnt) are displayed. -The frame counter shows how many frames have matched the specific rule, the byte -counter shows the sum of the frame sizes of these matching frames. Using this option -.BR "" "in combination with the " --Lx " option causes the counters to be written out" -.BR "" "in the '" -c " ' option format." -.br -.B "--Lx" -.br -Changes the output so that it produces a set of ebtables commands that construct -the contents of the chain, when specified. -If no chain is specified, ebtables commands to construct the contents of the -table are given, including commands for creating the user-defined chains (if any). -You can use this set of commands in an ebtables boot or reload -script. For example the output could be used at system startup. -The -.B "--Lx" -option is incompatible with the -.B "--Ln" -listing option. Using the -.BR --Lx " option together with the " --Lc " option will cause the counters to be written out" -.BR "" "in the '" -c " ' option format." -.br -.B "--Lmac2" -.br -Shows all MAC addresses with the same length, adding leading zeroes -if necessary. The default representation omits leading zeroes in the addresses. -.TP -.B "-N, --new-chain" -Create a new user-defined chain with the given name. The number of -user-defined chains is limited only by the number of possible chain names. -A user-defined chain name has a maximum -length of 31 characters. The standard policy of the user-defined chain is -ACCEPT. The policy of the new chain can be initialized to a different standard -target by using the -.B -P -command together with the -.B -N -command. In this case, the chain name does not have to be specified for the -.B -P -command. -.TP -.B "-X, --delete-chain" -Delete the specified user-defined chain. There must be no remaining references (jumps) -to the specified chain, otherwise ebtables will refuse to delete it. If no chain is -specified, all user-defined chains that aren't referenced will be removed. -.TP -.B "-E, --rename-chain" -Rename the specified chain to a new name. Besides renaming a user-defined -chain, you can rename a standard chain to a name that suits your -taste. For example, if you like PREFORWARDING more than PREROUTING, -then you can use the -E command to rename the PREROUTING chain. If you do -rename one of the standard ebtables chain names, please be sure to mention -this fact should you post a question on the ebtables mailing lists. -It would be wise to use the standard name in your post. Renaming a standard -ebtables chain in this fashion has no effect on the structure or functioning -of the ebtables kernel table. -.TP -.B "--init-table" -Replace the current table data by the initial table data. -.TP -.B "--atomic-init" -Copy the kernel's initial data of the table to the specified -file. This can be used as the first action, after which rules are added -to the file. The file can be specified using the -.B --atomic-file -command or through the -.IR EBTABLES_ATOMIC_FILE " environment variable." -.TP -.B "--atomic-save" -Copy the kernel's current data of the table to the specified -file. This can be used as the first action, after which rules are added -to the file. The file can be specified using the -.B --atomic-file -command or through the -.IR EBTABLES_ATOMIC_FILE " environment variable." -.TP -.B "--atomic-commit" -Replace the kernel table data with the data contained in the specified -file. This is a useful command that allows you to load all your rules of a -certain table into the kernel at once, saving the kernel a lot of precious -time and allowing atomic updates of the tables. The file which contains -the table data is constructed by using either the -.B "--atomic-init" -or the -.B "--atomic-save" -command to generate a starting file. After that, using the -.B "--atomic-file" -command when constructing rules or setting the -.IR EBTABLES_ATOMIC_FILE " environment variable" -allows you to extend the file and build the complete table before -committing it to the kernel. This command can be very useful in boot scripts -to populate the ebtables tables in a fast way. -.SS MISCELLANOUS COMMANDS -.TP -.B "-V, --version" -Show the version of the ebtables userspace program. -.TP -.BR "-h, --help " "[\fIlist of module names\fP]" -Give a brief description of the command syntax. Here you can also specify -names of extensions and ebtables will try to write help about those -extensions. E.g. -.IR "ebtables -h snat log ip arp" . -Specify -.I list_extensions -to list all extensions supported by the userspace -utility. -.TP -.BR "-j, --jump " "\fItarget\fP" -The target of the rule. This is one of the following values: -.BR ACCEPT , -.BR DROP , -.BR CONTINUE , -.BR RETURN , -a target extension (see -.BR "TARGET EXTENSIONS" ")" -or a user-defined chain name. -.TP -.B --atomic-file "\fIfile\fP" -Let the command operate on the specified -.IR file . -The data of the table to -operate on will be extracted from the file and the result of the operation -will be saved back into the file. If specified, this option should come -before the command specification. An alternative that should be preferred, -is setting the -.IR EBTABLES_ATOMIC_FILE " environment variable." -.TP -.B -M, --modprobe "\fIprogram\fP" -When talking to the kernel, use this -.I program -to try to automatically load missing kernel modules. -.TP -.B --concurrent -Use a file lock to support concurrent scripts updating the ebtables kernel tables. - -.SS -RULE SPECIFICATIONS -The following command line arguments make up a rule specification (as used -in the add and delete commands). A "!" option before the specification -inverts the test for that specification. Apart from these standard rule -specifications there are some other command line arguments of interest. -See both the -.BR "MATCH EXTENSIONS" -and the -.BR "WATCHER EXTENSIONS" -below. -.TP -.BR "-p, --protocol " "[!] \fIprotocol\fP" -The protocol that was responsible for creating the frame. This can be a -hexadecimal number, above -.IR 0x0600 , -a name (e.g. -.I ARP -) or -.BR LENGTH . -The protocol field of the Ethernet frame can be used to denote the -length of the header (802.2/802.3 networks). When the value of that field is -below or equals -.IR 0x0600 , -the value equals the size of the header and shouldn't be used as a -protocol number. Instead, all frames where the protocol field is used as -the length field are assumed to be of the same 'protocol'. The protocol -name used in ebtables for these frames is -.BR LENGTH . -.br -The file -.B /etc/ethertypes -can be used to show readable -characters instead of hexadecimal numbers for the protocols. For example, -.I 0x0800 -will be represented by -.IR IPV4 . -The use of this file is not case sensitive. -See that file for more information. The flag -.B --proto -is an alias for this option. -.TP -.BR "-i, --in-interface " "[!] \fIname\fP" -The interface (bridge port) via which a frame is received (this option is useful in the -.BR INPUT , -.BR FORWARD , -.BR PREROUTING " and " BROUTING -chains).

If the interface name ends with '+', then -any interface name that begins with this name (disregarding '+') will match. -The flag -.B --out-if -is an alias for this option. -.TP -.BR "--logical-out " "[!] \fIname\fP" -The (logical) bridge interface via which a frame is going to be sent (this option -is useful in the -.BR OUTPUT , -.B FORWARD -and -.B POSTROUTING -chains). -If the interface name ends with '+', then -any interface name that begins with this name (disregarding '+') will match. -.TP -.BR "-s, --source " "[!] \fIaddress\fP[/\fImask\fP]" -The source MAC address. Both mask and address are written as 6 hexadecimal -numbers separated by colons. Alternatively one can specify Unicast, -Multicast, Broadcast or BGA (Bridge Group Address): -.br -.IR "Unicast" "=00:00:00:00:00:00/01:00:00:00:00:00," -.IR "Multicast" "=01:00:00:00:00:00/01:00:00:00:00:00," -.IR "Broadcast" "=ff:ff:ff:ff:ff:ff/ff:ff:ff:ff:ff:ff or" -.IR "BGA" "=01:80:c2:00:00:00/ff:ff:ff:ff:ff:ff." -Note that a broadcast -address will also match the multicast specification. The flag -.B --src -is an alias for this option. -.TP -.BR "-d, --destination " "[!] \fIaddress\fP[/\fImask\fP]" -The destination MAC address. See -.B -s -(above) for more details on MAC addresses. The flag -.B --dst -is an alias for this option. -.TP -.BR "-c, --set-counter " "\fIpcnt bcnt\fP" -If used with -.BR -A " or " -I ", then the packet and byte counters of the new rule will be set to -.IR pcnt ", resp. " bcnt ". -If used with the -.BR -C " or " -D " commands, only rules with a packet and byte count equal to" -.IR pcnt ", resp. " bcnt " will match." - -.SS MATCH EXTENSIONS -Ebtables extensions are dynamically loaded into the userspace tool, -there is therefore no need to explicitly load them with a --m option like is done in iptables. -These extensions deal with functionality supported by kernel modules supplemental to -the core ebtables code. -.SS 802_3 -Specify 802.3 DSAP/SSAP fields or SNAP type. The protocol must be specified as -.IR "LENGTH " "(see the option " " -p " above). -.TP -.BR "--802_3-sap " "[!] \fIsap\fP" -DSAP and SSAP are two one byte 802.3 fields. The bytes are always -equal, so only one byte (hexadecimal) is needed as an argument. -.TP -.BR "--802_3-type " "[!] \fItype\fP" -If the 802.3 DSAP and SSAP values are 0xaa then the SNAP type field must -be consulted to determine the payload protocol. This is a two byte -(hexadecimal) argument. Only 802.3 frames with DSAP/SSAP 0xaa are -checked for type. -.SS among -Match a MAC address or MAC/IP address pair versus a list of MAC addresses -and MAC/IP address pairs. -A list entry has the following format: -.IR xx:xx:xx:xx:xx:xx[=ip.ip.ip.ip][,] ". Multiple" -list entries are separated by a comma, specifying an IP address corresponding to -the MAC address is optional. Multiple MAC/IP address pairs with the same MAC address -but different IP address (and vice versa) can be specified. If the MAC address doesn't -match any entry from the list, the frame doesn't match the rule (unless "!" was used). -.TP -.BR "--among-dst " "[!] \fIlist\fP" -Compare the MAC destination to the given list. If the Ethernet frame has type -.IR IPv4 " or " ARP , -then comparison with MAC/IP destination address pairs from the -list is possible. -.TP -.BR "--among-src " "[!] \fIlist\fP" -Compare the MAC source to the given list. If the Ethernet frame has type -.IR IPv4 " or " ARP , -then comparison with MAC/IP source address pairs from the list -is possible. -.TP -.BR "--among-dst-file " "[!] \fIfile\fP" -Same as -.BR --among-dst " but the list is read in from the specified file." -.TP -.BR "--among-src-file " "[!] \fIfile\fP" -Same as -.BR --among-src " but the list is read in from the specified file." -.SS arp -Specify (R)ARP fields.

The default value is 1. -.TP -.B --nflog-prefix "\fIprefix\fP" -.br -A prefix string to include in the log message, up to 30 characters -long, useful for distinguishing messages in the logs. -.TP -.B --nflog-range "\fIsize\fP" -.br -The number of bytes to be copied to userspace (only applicable for -nfnetlink_log). nfnetlink_log instances may specify their own -range, this option overrides it. -.TP -.B --nflog-threshold "\fIsize\fP" -.br -Number of packets to queue inside the kernel before sending them -to userspace (only applicable for nfnetlink_log). Higher values -result in less overhead per packet, but increase delay until the -packets reach userspace. The default value is 1. -.SS ulog -The ulog watcher passes the packet to a userspace -logging daemon using netlink multicast sockets. This differs -from the log watcher in the sense that the complete packet is -sent to userspace instead of a descriptive text and that -netlink multicast sockets are used instead of the syslog. -This watcher enables parsing of packets with userspace programs, the -physical bridge in and out ports are also included in the netlink messages. -The ulog watcher module accepts 2 parameters when the module is loaded -into the kernel (e.g. with modprobe): -.B nlbufsiz -specifies how big the buffer for each netlink multicast -group is. If you say -.IR nlbufsiz=8192 , -for example, up to eight kB of packets will -get accumulated in the kernel until they are sent to userspace. It is -not possible to allocate more than 128kB. Please also keep in mind that -this buffer size is allocated for each nlgroup you are using, so the -total kernel memory usage increases by that factor. The default is 4096. -.B flushtimeout -specifies after how many hundredths of a second the queue should be -flushed, even if it is not full yet. The default is 10 (one tenth of -a second). -.TP -.B "--ulog" -.br -Use the default settings: ulog-prefix="", ulog-nlgroup=1, -ulog-cprange=4096, ulog-qthreshold=1. -.TP -.B --ulog-prefix "\fItext\fP" -.br -Defines the prefix included with the packets sent to userspace. -.TP -.BR --ulog-nlgroup " \fIgroup\fP" -.br -Defines which netlink group number to use (a number from 1 to 32). -Make sure the netlink group numbers used for the iptables ULOG -target differ from those used for the ebtables ulog watcher. -The default group number is 1. -.TP -.BR --ulog-cprange " \fIrange\fP" -.br -Defines the maximum copy range to userspace, for packets matching the -rule. The default range is 0, which means the maximum copy range is -given by -.BR nlbufsiz . -A maximum copy range larger than -128*1024 is meaningless as the packets sent to userspace have an upper -size limit of 128*1024. -.TP -.BR --ulog-qthreshold " \fIthreshold\fP" -.br -Queue at most -.I threshold -number of packets before sending them to -userspace with a netlink socket. Note that packets can be sent to -userspace before the queue is full, this happens when the ulog -kernel timer goes off (the frequency of this timer depends on -.BR flushtimeout ). -.SS TARGET EXTENSIONS -.SS arpreply -The -.B arpreply -target can be used in the -.BR PREROUTING " chain of the " nat " table." -If this target sees an ARP request it will automatically reply -with an ARP reply. The used MAC address for the reply can be specified. -The protocol must be specified as -.IR ARP . -When the ARP message is not an ARP request or when the ARP request isn't -for an IP address on an Ethernet network, it is ignored by this target -.BR "" ( CONTINUE ). -When the ARP request is malformed, it is dropped -.BR "" ( DROP ). -.TP -.BR "--arpreply-mac " "\fIaddress\fP" -Specifies the MAC address to reply with: the Ethernet source MAC and the -ARP payload source MAC will be filled in with this address. -.TP -.BR "--arpreply-target " "\fItarget\fP" -Specifies the standard target. After sending the ARP reply, the rule still -has to give a standard target so ebtables knows what to do with the ARP request. -The default target -.BR "" "is " DROP . -.SS dnat -The -.B dnat -target can only be used in the -.BR PREROUTING " and " OUTPUT " chains of the " nat " table." -It specifies that the destination MAC address has to be changed. -.TP -.BR "--to-destination " "\fIaddress\fP" -.br -Change the destination MAC address to the specified -.IR address . -The flag -.B --to-dst -is an alias for this option. -.TP -.BR "--dnat-target " "\fItarget\fP" -.br -Specifies the standard target. After doing the dnat, the rule still has to -give a standard target so ebtables knows what to do with the dnated frame. -The default target is -.BR ACCEPT . -Making it -.BR CONTINUE " could let you use" -multiple target extensions on the same frame. Making it -.BR DROP " only makes" -sense in the -.BR BROUTING " chain but using the " redirect " target is more logical there. " RETURN " is also allowed. Note that using " RETURN -in a base chain is not allowed (for obvious reasons). -.SS mark -.BR "" "The " mark " target can be used in every chain of every table. It is possible" -to use the marking of a frame/packet in both ebtables and iptables, -if the bridge-nf code is compiled into the kernel. Both put the marking at the -same place.

After marking the frame, the rule -still has to give a standard target so ebtables knows what to do. -The default target is -.BR ACCEPT ". Making it " CONTINUE " can let you do other" -things with the frame in subsequent rules of the chain. -.SS redirect -The -.B redirect -target will change the MAC target address to that of the bridge device the -frame arrived on. This target can only be used in the -.BR PREROUTING " chain of the " nat " table." -The MAC address of the bridge is used as destination address." -.TP -.BR "--redirect-target " "\fItarget\fP" -.br -Specifies the standard target.
