[PATCH] media: uvc: Avoid cyclic entity chains due to malformed USB descriptors

by Will Deacon

Way back in 2017, fuzzing the 4.14-rc2 USB stack with syzkaller kicked up the following WARNING from the UVC chain scanning code: | list_add double add: new=ffff880069084010, prev=ffff880069084010, | next=ffff880067d22298. | ------------[ cut here ]------------ | WARNING: CPU: 1 PID: 1846 at lib/list_debug.c:31 __list_add_valid+0xbd/0xf0 | Modules linked in: | CPU: 1 PID: 1846 Comm: kworker/1:2 Not tainted | 4.14.0-rc2-42613-g1488251d1a98 #238 | Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Bochs 01/01/2011 | Workqueue: usb_hub_wq hub_event | task: ffff88006b01ca40 task.stack: ffff880064358000 | RIP: 0010:__list_add_valid+0xbd/0xf0 lib/list_debug.c:29 | RSP: 0018:ffff88006435ddd0 EFLAGS: 00010286 | RAX: 0000000000000058 RBX: ffff880067d22298 RCX: 0000000000000000 | RDX: 0000000000000058 RSI: ffffffff85a58800 RDI: ffffed000c86bbac | RBP: ffff88006435dde8 R08: 1ffff1000c86ba52 R09: 0000000000000000 | R10: 0000000000000002 R11: 0000000000000000 R12: ffff880069084010 | R13: ffff880067d22298 R14: ffff880069084010 R15: ffff880067d222a0 | FS: 0000000000000000(0000) GS:ffff88006c900000(0000) knlGS:0000000000000000 | CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 | CR2: 0000000020004ff2 CR3: 000000006b447000 CR4: 00000000000006e0 | Call Trace: | __list_add ./include/linux/list.h:59 | list_add_tail+0x8c/0x1b0 ./include/linux/list.h:92 | uvc_scan_chain_forward.isra.8+0x373/0x416 | drivers/media/usb/uvc/uvc_driver.c:1471 | uvc_scan_chain drivers/media/usb/uvc/uvc_driver.c:1585 | uvc_scan_device drivers/media/usb/uvc/uvc_driver.c:1769 | uvc_probe+0x77f2/0x8f00 drivers/media/usb/uvc/uvc_driver.c:2104 Looking into the output from usbmon, the interesting part is the following data packet: ffff880069c63e00 30710169 C Ci:1:002:0 0 143 = 09028f00 01030080 00090403 00000e01 00000924 03000103 7c003328 010204db If we drop the lead configuration and interface descriptors, we're left with an output terminal descriptor describing a generic display: /* Output terminal descriptor */ buf[0] 09 buf[1] 24 buf[2] 03 /* UVC_VC_OUTPUT_TERMINAL */ buf[3] 00 /* ID */ buf[4] 01 /* type == 0x0301 (UVC_OTT_DISPLAY) */ buf[5] 03 buf[6] 7c buf[7] 00 /* source ID refers to self! */ buf[8] 33 The problem with this descriptor is that it is self-referential: the source ID of 0 matches itself! This causes the 'struct uvc_entity' representing the display to be added to its chain list twice during 'uvc_scan_chain()': once via 'uvc_scan_chain_entity()' when it is processed directly from the 'dev->entities' list and then again immediately afterwards when trying to follow the source ID in 'uvc_scan_chain_forward()' Add a check before adding an entity to a chain list to ensure that the entity is not already part of a chain.

[PATCH v2] taskstats: fix data-race

by Christian Brauner

When assiging and testing taskstats in taskstats_exit() there's a race when writing and reading sig->stats when a thread-group with more than one thread exits: cpu0: thread catches fatal signal and whole thread-group gets taken down do_exit() do_group_exit() taskstats_exit() taskstats_tgid_alloc() The tasks reads sig->stats holding sighand lock seeing garbage. cpu1: task calls exit_group() do_exit() do_group_exit() taskstats_exit() taskstats_tgid_alloc() The task takes sighand lock and assigns new stats to sig->stats. Fix this by using READ_ONCE() and smp_store_release().

[PATCH v2 0/8] Backported fixes for 4.4 stable tree

by Ajay Kaher

These patches include few backported fixes for the 4.4 stable tree. I would appreciate if you could kindly consider including them in the next release. Ajay --- [Changes from v1]: No changes, only answering Greg's below queries: >> Why are these needed? From what I remember, the last patch here is only >> needed for machines that are "HUGE" and for those, you shouldn't be >> using 4.4.y anymore anyway, right? You just end up saving so much more >> speed and energy using a newer kernel, why would you want to waste it >> using an older one? >> >> So I need a really good reason why to accept these :) > > It's been a week, so I'm dropping this from my queue now. Please resend > with this information if you still want these in the tree. > thanks, > greg k-h Indeed, the machine needs to have about 140 GB of RAM to exploit this vulnerability (CVE-2019-11487). However, Photon OS doesn't impose any limits on the amount of RAM that it supports, so we would like to safeguard the kernel against this CVE. Also, while newer versions of Photon OS are on more recent kernels, Photon OS 1.0 uses the 4.4 stable series, so it would be great to get these patches included in an upcoming 4.4 stable release. We would also like to have the following patches that are for machines that are huge: Patch 1: Introduced page_ref_zero_or_close_to_overflow() which helps to check for small underflows (or _very_ close to overflowing), and ignore overflows which have strayed into negative territory. And this is being used inside get_page() and get_page_foll() to reduce the possibility of overflowing. Patch 6: Attacker could do direct IO on a page multiple times to trigger an overflowing. This patch makes get_user_pages() refuse to if there is an overflow. Patch 8: This removes another mechanism for overflowing the page refcount inside pipe_buf_get(). --- [PATCH v2 1/8]: Backporting of upstream commit f958d7b528b1: mm: make page ref count overflow check tighter and more explicit [PATCH v2 2/8]: Backporting of upstream commit 88b1a17dfc3e: mm: add 'try_get_page()' helper function [PATCH v2 3/8]: Backporting of upstream commit 7aef4172c795: mm: handle PTE-mapped tail pages in gerneric fast gup implementaiton [PATCH v2 4/8]: Backporting of upstream commit a3e328556d41: mm, gup: remove broken VM_BUG_ON_PAGE compound check for hugepages [PATCH v2 5/8]: Backporting of upstream commit d63206ee32b6: mm, gup: ensure real head page is ref-counted when using hugepages [PATCH v2 6/8]: Backporting of upstream commit 8fde12ca79af: mm: prevent get_user_pages() from overflowing page refcount [PATCH v2 7/8]: Backporting of upstream commit 7bf2d1df8082: pipe: add pipe_buf_get() helper [PATCH v2 8/8]: Backporting of upstream commit 15fab63e1e57: fs: prevent page refcount overflow in pipe_buf_get

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
