RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Stefano Brivio 2018-03-17 01:52:20 UTC 
We now have customer bugs requesting features that have been introduced upstream quite recently, and it would be impractical and risky to introduce them with the big gap we currently have in our codebase.

We had recent, critical bugs, that were fixed upstream, but we couldn't conveniently backport any patch, and we had to resort to RHEL-only patches. See e.g. bz1517397.

Furthermore, the userspace component is more recent than the kernel implementation, and supports set types that are not supported in kernel, causing obvious inconsistencies. Also the current upstream test suite is unusable with our current kernel implementation.

This poses a strong case for a rebase of the kernel component.
Comment 5 Bruno Meneguele 2018-05-29 10:06:21 UTC 
Patch(es) committed on kernel repository and an interim kernel build is undergoing testing
Comment 6 Bruno Meneguele 2018-05-29 10:39:39 UTC 
Patch(es) available on kernel-3.10.0-894.el7
Comment 9 yiche 2018-07-20 06:57:46 UTC 
I have run upstream test: git clone git://git.netfilter.org/ipset on kernel-3.10.0-898.el7 and get result:
https://beaker.engineering.redhat.com/recipes/5307771#task74304094
all items gone through


review result.log，there is only one item failed:
Failed test: ./check_klog.sh 10.255.255.64 udp 1025 netiface

that because when exec 
sendip -p ipv4 -id 10.255.255.254 -is 10.255.255.64 -p udp -ud 80 -us 1025 10.255.255.254

there is a few iptables rule remain:
Chain OUTPUT (policy ACCEPT 29 packets, 3576 bytes)
pkts bytes target     prot opt in     out     source               destination         
    0     0 LOG        all  --  *      *       0.0.0.0/0            0.0.0.0/0            match-set test dst,dst LOG flags 0 level 4 prefix "in set netiface: "
    1    28 DROP       all  --  *      *       0.0.0.0/0      10.255.255.254 

That drop cause sendto() EPERM (Operation not permitted). sendip use RAW socket to generate IP payload.

I don't think it's a issue.
Comment 10 yiche 2018-07-20 07:17:03 UTC 
I also cover these type: 
- hash:net,net
- hash:net,port,net
- hash:ip,mark
- hash:ip,mac
basic function works fine.
no issue found.
Comment 12 yiche 2018-08-02 02:12:11 UTC 
There is a issue hash:mac can't be matched as a destination MAC address.

Hi Yi Chen,

(In reply to yiche from comment #12)

> There is a issue hash:mac can't be matched as a destination MAC address. 
> Bug 1607252

Wouldn't it make sense to keep this as VERIFIED, though, and track the additional issue separately?
Comment 15 yiche 2018-08-03 01:01:06 UTC 
Ok，We can track it separately.
