Hi,

The following patchset contains Netfilter fixes for net:

1) Add missing netfilter modules description to fix W=1, from Florian Westphal.

2) Fix catch-all element GC with timeout when use with the pipapo set
   backend, this remained broken since I tried to fix it this summer,
   then another attempt to fix it recently.

3) Add missing IPVS modules descriptions to fix W=1, also from Florian.

4) xt_recent allocated a too small buffer to store an IPv4-mapped IPv6
   address which can be parsed by in6_pton(), from Maciej Zenczykowski.
   Broken for many releases.

5) Skip IPv4-mapped IPv6, IPv4-compat IPv6, site/link local scoped IPv6
   addressses to set up IPv6 NAT redirect, also from Florian. This is
   broken since 2012.

Please, pull these changes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf.git nf-23-11-08

Thanks.

Hi,

The following patchset contains Netfilter fixes for net:

1) Zero out the remainder in nft_pipapo AVX2 implementation, otherwise
   next lookup could bogusly report a mismatch. This is followed by two
   patches to update nft_pipapo selftests to cover for the previous bug.
   From Florian Westphal.

2) Check for reverse tuple too in case of esoteric NAT collisions for
   UDP traffic and extend selftest coverage. Also from Florian.

Please, pull these changes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf.git nf-25-06-05

Thanks.

Hi,

The following patchset contains Netfilter fixes for net:

Patch #1 fixes the suspicious RCU usage warning that resulted from the
	 recent fix for the race between namespace cleanup and gc in
	 ipset left out checking the pernet exit phase when calling
	 rcu_dereference_protected(), from Jozsef Kadlecsik.

Patch #2 fixes incorrect input and output netdevice in SRv6 prerouting
	 hooks, from Jianguo Wu.

Patch #3 moves nf_hooks_lwtunnel sysctl toggle to the netfilter core.
	 The connection tracking system is loaded on-demand, this
	 ensures availability of this knob regardless.

Patch #4-#5 adds selftests for SRv6 netfilter hooks also from Jianguo Wu.

Hi,

The following patchset contains fixes for net:

Patch #1 disallows anonymous sets with timeout, except for dynamic sets.
         Anonymous sets with timeouts using the pipapo set backend makes
         no sense from userspace perspective.

Patch #2 rejects constant sets with timeout which has no practical usecase.
         This kind of set, once bound, contains elements that expire but
         no new elements can be added.

Patch #3 restores custom conntrack expectations with NFPROTO_INET,
         from Florian Westphal.

Patch #4 marks rhashtable anonymous set with timeout as dead from the
         commit path to avoid that async GC collects these elements. Rules
         that refers to the anonymous set get released with no mutex held
         from the commit path.

Patch #5 fixes a UBSAN shift overflow in H.323 conntrack helper,
         from Lena Wang.

Please, pull these changes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf.git nf-24-03-07

Hi,

The following patchset contains Netfilter fixes for net:

1) If user requests to wake up a table and hook fails, restore the
   dormant flag from the error path, from Florian Westphal.

2) Reset dst after transferring it to the flow object, otherwise dst
   gets released twice from the error path.

3) Release dst in case the flowtable selects a direct xmit path, eg.
   transmission to bridge port. Otherwise, dst is memleaked.

4) Register basechain and flowtable hooks at the end of the command.
   Error path releases these datastructure without waiting for the
   rcu grace period.

5) Use kzalloc() to initialize struct nft_hook to fix a KMSAN report
   on access to hook type, also from Florian Westphal.

Hi,

The following patchset contains Netfilter fixes for net:

1) Fix mangling of TCP options with non-linear skbuff, from Xiao Liang.

2) OOB read in xt_sctp due to missing sanitization of array length field.
   From Wander Lairson Costa.

3) OOB read in xt_u32 due to missing sanitization of array length field.
   Also from Wander Lairson Costa.

All of them above, always broken for several releases.

4) Missing audit log for set element reset command, from Phil Sutter.

5) Missing audit log for rule reset command, also from Phil.

These audit log support are missing in 6.5.

Hi,

The following patchset contains Netfilter fixes for net.

The existing attempt to resolve races between control plane and GC work
is error prone, as reported by Bien Pham <phamnnb@sea.com>, some places
forgot to call nft_set_elem_mark_busy(), leading to double-deactivation
of elements.

This series contains the following patches:

1) Do not skip expired elements during walk otherwise elements might
   never decrement the reference counter on data, leading to memleak.

2) Add a GC transaction API to replace the former attempt to deal with
   races between control plane and GC. GC worker sets on NFT_SET_ELEM_DEAD_BIT
   on elements and it creates a GC transaction to remove the expired
   elements, GC transaction could abort in case of interference with
   control plane and retried later (GC async). Set backends such as
   rbtree and pipapo also perform GC from control plane (GC sync), in
   such case, element deactivation and removal is safe because mutex
   is held then collected elements are released via call_rcu().

3) Adapt existing set backends to use the GC transaction API.

4) Update rhash set backend to set on _DEAD bit to report deleted
   elements from datapath for GC.

5) Remove old GC batch API and the NFT_SET_ELEM_BUSY_BIT.

Hi,

The following patchset contains Netfilter fixes for net:

1) Move back the defrag users fields to the global netns_nf area.
   Kernel fails to boot if conntrack is builtin and kernel is booted
   with: nf_conntrack.enable_hooks=1. From Florian Westphal.

2) Rule event notification is missing relevant context such as
   the position handle and the NLM_F_APPEND flag.

3) Rule replacement is expanded to add + delete using the existing
   rule handle, reverse order of this operation so it makes sense
   from rule notification standpoint.

4) Remove superfluous check in the dynamic set extension which
   disallow update commands on a set without timeout.

5) Propagate to userspace the NLM_F_CREATE and NLM_F_EXCL flags
   from the rule notification path.

  git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf.git

Hi,

The following patchset contains Netfilter fixes for net:

1) Protect nft_ct template with global mutex, from Pavel Skripkin.

2) Two recent commits switched inet rt and nexthop exception hashes
   from jhash to siphash. If those two spots are problematic then
   conntrack is affected as well, so switch voer to siphash too.
   While at it, add a hard upper limit on chain lengths and reject
   insertion if this is hit. Patches from Florian Westphal.

3) Fix use-after-scope in nf_socket_ipv6 reported by KASAN,
   from Benjamin Hesmans.

Hi,

The following patchset contains Netfilter fixes for net:

1) Fix insufficient validation of IPSET_ATTR_IPADDR_IPV6 reported
   by syzbot.

2) Remove spurious reports on nf_tables when lockdep gets disabled,

3) Fix memleak in the error path of error path of
   ip_vs_control_net_init(), from Wang Hai.

4) Fix missing control data in flow dissector, otherwise IP address
   matching in hardware offload infra does not work.

5) Fix hardware offload match on prefix IP address when userspace
   does not send a bitwise expression to represent the prefix.

Hi,

The following patchset contains Netfilter fixes for net:

1) Incorrect netlink report logic in flowtable and genID.

2) Add a selftest to check that wireguard passes the right sk
   to ip_route_me_harder, from Jason A. Donenfeld.

3) Pass the actual sk to ip_route_me_harder(), also from Jason.

4) Missing expression validation of updates via nft --check.

5) Update byte and packet counters regardless of whether they
   match, from Stefano Brivio.
