[PATCH v1] power: supply: ltc2941-battery-gauge: fix use-after-free

by Sven Van Asbroeck

This driver's remove path calls cancel_delayed_work(). However, that function does not wait until the work function finishes. This could mean that the work function is still running after the driver's remove function has finished, which would result in a use-after-free. Fix by calling cancel_delayed_work_sync(), which ensures that that the work is properly cancelled, no longer running, and unable to re-schedule itself. This issue was detected with the help of Coccinelle.

[PATCH 2/3] genirq/irqdomain: Re-check mapping after associate in irq_create_mapping()

by Sverdlin, Alexander (Nokia - DE/Ulm)

From: Alexander Sverdlin <alexander.sverdlin(a)nokia.com> If two irq_create_mapping() calls perform a mapping of the same hwirq on two CPU cores in parallel they both will get 0 from irq_find_mapping(), both will allocate unique virq using irq_domain_alloc_descs() and both will finally irq_domain_associate() it. Giving different virq numbers to their callers. In practice the first caller is usually an interrupt controller driver and the seconds is some device requesting the interrupt providede by the above interrupt controller. In this case either the interrupt controller driver configures virq which is not the one being "associated" with hwirq, or the "slave" device requests the virq which is never being triggered.

Back-porting request

by Stephen Suryaputra

Hello, I'm requesting this commit to be back-ported to v4.14: --- commit 5b18f1289808fee5d04a7e6ecf200189f41a4db6 Author: Stephen Suryaputra <ssuryaextr(a)gmail.com> Date: Wed Jun 26 02:21:16 2019 -0400 ipv4: reset rt_iif for recirculated mcast/bcast out pkts Multicast or broadcast egress packets have rt_iif set to the oif. These packets might be recirculated back as input and lookup to the raw sockets may fail because they are bound to the incoming interface (skb_iif). If rt_iif is not zero, during the lookup, inet_iif() function returns rt_iif instead of skb_iif. Hence, the lookup fails. v2: Make it non vrf specific (David Ahern).

[PATCH AUTOSEL 4.20 001/117] netfilter: ipset: Allow matching on destination MAC address for mac and ipmac sets

by Sasha Levin

From: Stefano Brivio <sbrivio(a)redhat.com> [ Upstream commit 8cc4ccf58379935f3ad456cc34e61c4e4c921d0e ] There doesn't seem to be any reason to restrict MAC address matching to source MAC addresses in set types bitmap:ipmac, hash:ipmac and hash:mac. With this patch, and this setup: ip netns add A ip link add veth1 type veth peer name veth2 netns A ip addr add 192.0.2.1/24 dev veth1 ip -net A addr add 192.0.2.2/24 dev veth2 ip link set veth1 up ip -net A link set veth2 up ip netns exec A ipset create test hash:mac dst=$(ip netns exec A cat /sys/class/net/veth2/address) ip netns exec A ipset add test ${dst} ip netns exec A iptables -P INPUT DROP ip netns exec A iptables -I INPUT -m set --match-set test dst -j ACCEPT ipset will match packets based on destination MAC address: # ping -c1 192.0.2.2 >/dev/null # echo $? 0 Reported-by: Yi Chen <yiche(a)redhat.com> Signed-off-by: Stefano Brivio <sbrivio(a)redhat.com> Signed-off-by: Jozsef Kadlecsik <kadlec(a)blackhole.kfki.hu> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- net/netfilter/ipset/ip_set_bitmap_ipmac.c | 10 +++++----- net/netfilter/ipset/ip_set_hash_ipmac.c | 16 ++++++++++------ net/netfilter/ipset/ip_set_hash_mac.c | 10 +++++----- 3 files changed, 20 insertions(+), 16 deletions(-) diff --git a/net/netfilter/ipset/ip_set_bitmap_ipmac.c b/net/netfilter/ipset/ip_set_bitmap_ipmac.c index c00b6a2e8e3c..13ade5782847 100644 --- a/net/netfilter/ipset/ip_set_bitmap_ipmac.c +++ b/net/netfilter/ipset/ip_set_bitmap_ipmac.c @@ -219,10 +219,6 @@ bitmap_ipmac_kadt(struct ip_set *set, const struct sk_buff *skb, struct ip_set_ext ext = IP_SET_INIT_KEXT(skb, opt, set); u32 ip; - /* MAC can be src only */ - if (!(opt->flags & IPSET_DIM_TWO_SRC)) - return 0; - ip = ntohl(ip4addr(skb, opt->flags & IPSET_DIM_ONE_SRC)); if (ip < map->first_ip || ip > map->last_ip) return -IPSET_ERR_BITMAP_RANGE; @@ -233,7 +229,11 @@ bitmap_ipmac_kadt(struct ip_set *set, const struct sk_buff *skb, return -EINVAL; e.id = ip_to_id(map, ip); - memcpy(e.ether, eth_hdr(skb)->h_source, ETH_ALEN); + + if (opt->flags & IPSET_DIM_ONE_SRC) + ether_addr_copy(e.ether, eth_hdr(skb)->h_source); + else + ether_addr_copy(e.ether, eth_hdr(skb)->h_dest); return adtfn(set, &e, &ext, &opt->ext, opt->cmdflags); } diff --git a/net/netfilter/ipset/ip_set_hash_ipmac.c b/net/netfilter/ipset/ip_set_hash_ipmac.c index 1ab5ed2f6839..fd87de3ed55b 100644 --- a/net/netfilter/ipset/ip_set_hash_ipmac.c +++ b/net/netfilter/ipset/ip_set_hash_ipmac.c @@ -103,7 +103,11 @@ hash_ipmac4_kadt(struct ip_set *set, const struct sk_buff *skb, (skb_mac_header(skb) + ETH_HLEN) > skb->data) return -EINVAL; - memcpy(e.ether, eth_hdr(skb)->h_source, ETH_ALEN); + if (opt->flags & IPSET_DIM_ONE_SRC) + ether_addr_copy(e.ether, eth_hdr(skb)->h_source); + else + ether_addr_copy(e.ether, eth_hdr(skb)->h_dest); + if (ether_addr_equal(e.ether, invalid_ether)) return -EINVAL; @@ -211,15 +215,15 @@ hash_ipmac6_kadt(struct ip_set *set, const struct sk_buff *skb, }; struct ip_set_ext ext = IP_SET_INIT_KEXT(skb, opt, set); - /* MAC can be src only */ - if (!(opt->flags & IPSET_DIM_TWO_SRC)) - return 0; - if (skb_mac_header(skb) < skb->head || (skb_mac_header(skb) + ETH_HLEN) > skb->data) return -EINVAL; - memcpy(e.ether, eth_hdr(skb)->h_source, ETH_ALEN); + if (opt->flags & IPSET_DIM_ONE_SRC) + ether_addr_copy(e.ether, eth_hdr(skb)->h_source); + else + ether_addr_copy(e.ether, eth_hdr(skb)->h_dest); + if (ether_addr_equal(e.ether, invalid_ether)) return -EINVAL; diff --git a/net/netfilter/ipset/ip_set_hash_mac.c b/net/netfilter/ipset/ip_set_hash_mac.c index f9d5a2a1e3d0..4fe5f243d0a3 100644 --- a/net/netfilter/ipset/ip_set_hash_mac.c +++ b/net/netfilter/ipset/ip_set_hash_mac.c @@ -81,15 +81,15 @@ hash_mac4_kadt(struct ip_set *set, const struct sk_buff *skb, struct hash_mac4_elem e = { { .foo[0] = 0, .foo[1] = 0 } }; struct ip_set_ext ext = IP_SET_INIT_KEXT(skb, opt, set); - /* MAC can be src only */ - if (!(opt->flags & IPSET_DIM_ONE_SRC)) - return 0; - if (skb_mac_header(skb) < skb->head || (skb_mac_header(skb) + ETH_HLEN) > skb->data) return -EINVAL; - ether_addr_copy(e.ether, eth_hdr(skb)->h_source); + if (opt->flags & IPSET_DIM_ONE_SRC) + ether_addr_copy(e.ether, eth_hdr(skb)->h_source); + else + ether_addr_copy(e.ether, eth_hdr(skb)->h_dest); + if (is_zero_ether_addr(e.ether)) return -EINVAL; return adtfn(set, &e, &ext, &opt->ext, opt->cmdflags); -- 2.19.1
