* expr: hash: support of symmetric hashLaura Garcia Liebana2017-03-061-0/+13
| | | | | | | | | | | | | | | | | | | | | This patch provides symmetric hash support according to source ip address and port, and destination ip address and port. The new attribute NFTA_HASH_TYPE has been included to support different types of hashing functions. Currently supported NFT_HASH_JENKINS through jhash and NFT_HASH_SYM through symhash. The main difference between both types are: - jhash requires an expression with sreg, symhash doesn't. - symhash supports modulus and offset, but not seed. Examples: nft add rule ip nat prerouting ct mark set jhash ip saddr mod 2 nft add rule ip nat prerouting ct mark set symhash mod 2 Signed-off-by: Laura Garcia Liebana <laura.garcia@zevenet.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

| | | | | | | | Add range expression available that is scheduled for linux kernel 4.9. This range expression allows us to check if a given value placed in a register is within/outside a specified interval. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* expr: log: complete log flags supportLiping Zhang2016-10-041-0/+12
| | | | | | | | | If NFTNL_EXPR_LOG_FLAGS is not set, it's unnecessary to print out the flags value. Furthermore, it's better to print out string message instead of the hex value. Signed-off-by: Liping Zhang <liping.zhang@spreadtrum.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* expr: queue: add NFTA_QUEUE_SREG_QNUM attr supportLiping Zhang2016-09-221-0/+2
| | | | | | | | | | After adding _SREG_QNUM attr, queuenum is not must option anymore, so we must test NFTNL_EXPR_QUEUE_NUM first before dumpping queue num in snprintf_default. Also add a tailing space in snprintf_default, this is consistent with other expressions.

| | | | | | | | | | | | | | | | Add support to pass through an offset value to the counter initialization. With this feature, the sysadmin is able to apply a value to be added to the generated number. Example: meta mark set numgen inc mod 2 offset 100 This will generate marks with series 100, 101, 100, 101, ...

* expr: hash: Add offset to hash valueLaura Garcia Liebana2016-09-121-0/+2
| | | | | | | | | | | | | | | | Add support to pass through an offset to the hash value. With this feature, the sysadmin is able to generate a hash with a given started value. Example: meta mark set jhash ip saddr mod 2 seed 0xabcd offset 100 This option generates marks according to the source address from 100 to 101.

* expr: numgen: Rename until attribute by modulusLaura Garcia Liebana2016-09-071-2/+2
| | | | | | | | | | | The _modulus_ attribute will be reused as _until_, as it's similar to other expressions with value limits (ex. hash). Renaming is possible according to the kernel module ntf_numgen that has not been released yet.
