====================
Netfilter/IPVS fixes for net
The following batch contains Netfilter/IPVS fixes for net. This batch
includes a mix of IPVS follow ups related to Sashiko reports, as well as
crash fixes for connection tracking expectation, helpers, ipset and
nf_tables mostly for old bugs. This also includes a fix for the
flowtable tunnel selftest.
1) Use s32 instead of s16 to calculate the remaining payload containing
SIP messages, otherwise underflow is possible allowing out-of-bound
memory access beyond the skb->data area. From Xiang Mei.
2) Fix the counter check in the flowtable selftest for tunnels, from
Lorenzo Bianconi.
3) Add and use nf_ct_expect_related_pair() to add the RTP and RTCP
expectations under the expectation lock, this is required by the SIP
and H.323 NAT helpers. This fixes a possible reinsertion of an
expectation with the DEAD flag set on while looping to find
consecutive ports.
4) Fix ipset UaF during table resize by blocking comment updates on
kernel-side adds. From David Lee.
5) Do not propagate the IP_VS_CONN_F_ONE_PACKET flag when using IPVS
state synchronization, otherwise reaching stale freed from
ip_vs_conn struct is possible, Zhiling Zou.
6) Adjust the hn1 hash node when the forwarding method changes between
MASQ and non-MASQ for an already hashed connection. This can leave
stale hash nodes pointing to a freed struct ip_vs_conn and trigger
UaF while reading /proc/net/ip_vs_conn. From Julian Anastasov.
7) nft_object rhltable needs to be per table, just like chain rhltable,
otherwise UaF from object lookup path while netns is being released.
There is also the nlevent path that can reach stale objects. Placing
this rhltable under the table hierarchy fixes this issue.
8) Reject invalid combined usage of hashlimit tables with and without
XT_HASHLIMIT_RATE_MATCH flag mode, otherwise access to uninitialized
.burst field of dsthash_ent is possible.
9) Fix checksum validations in IPVS performed from LOCAL_IN,
from Julian Anastasov.
10) Fix incorrect packet offset to layer 4 protocol in IPVS, uncovered
by Sashiko, from Julian Anastasov.
11) Skip the mangling of ICMP replies for non-first fragments, also
reported by Sashiko. Also from Julian.
12) Clear ip_vs_conn flags under the spinlock to fix a possible data
race. From Julian Anastasov.
13) Fix incorrect calculation of the payload bitmask in the nf_tables
hardware offload support, leading to UBSAN splat. From Xiang Mei.
