[PATCH] netfilter: nat: check the bounds of nf_nat_l3protos and nf_nat_l4protos

29 Jul '20

hulk inclusion category: bugfix bugzilla: NA CVE: NA ------------------------------------------------- famliy can be passed from user space and will be out of range of nf_nat_l3protos or nf_nat_l4protos, so we need check the family when call __nf_nat_l3proto_find() or __nf_nat_l4proto_find(). nfnetlink_parse_nat_setup() need return EAGAIN, if __nf_nat_l3proto_find() returns null, so we return a error number to distinguish this case.

[PATCH 1/3] arm64: Add support for SB barrier and patch in over DSB; ISB sequences
by Yang Yingliang 29 Jul '20

29 Jul '20

From: Will Deacon <will.deacon(a)arm.com> mainline inclusion from v5.0-rc1 commit bd4fb6d270bc423a9a4098108784f7f9254c4e6d category: feature bugzilla: 30102 CVE: NA ------------------------------------------------- We currently use a DSB; ISB sequence to inhibit speculation in set_fs(). Whilst this works for current CPUs, future CPUs may implement a new SB barrier instruction which acts as an architected speculation barrier. On CPUs that support it, patch in an SB; NOP sequence over the DSB; ISB sequence and advertise the presence of the new instruction to userspace.

[PATCH] kernel/notifier.c: intercept duplicate registrations to avoid infinite loops
by Yang Yingliang 29 Jul '20

29 Jul '20

From: Xiaoming Ni <nixiaoming(a)huawei.com> mainline inclusion from mainline-v5.5-rc1 commit 1a50cb80f219c44adb6265f5071b81fc3c1deced category: bugfix bugzilla: NA CVE: NA --------------------------------------------- [ Upstream commit 1a50cb80f219c44adb6265f5071b81fc3c1deced ] Registering the same notifier to a hook repeatedly can cause the hook list to form a ring or lose other members of the list. case1: An infinite loop in notifier_chain_register() can cause soft lockup atomic_notifier_chain_register(&test_notifier_list, &test1); atomic_notifier_chain_register(&test_notifier_list, &test1); atomic_notifier_chain_register(&test_notifier_list, &test2); case2: An infinite loop in notifier_chain_register() can cause soft lockup atomic_notifier_chain_register(&test_notifier_list, &test1); atomic_notifier_chain_register(&test_notifier_list, &test1); atomic_notifier_call_chain(&test_notifier_list, 0, NULL); case3: lose other hook test2 atomic_notifier_chain_register(&test_notifier_list, &test1); atomic_notifier_chain_register(&test_notifier_list, &test2); atomic_notifier_chain_register(&test_notifier_list, &test1); case4: Unregister returns 0, but the hook is still in the linked list, and it is not really registered. If you call notifier_call_chain after ko is unloaded, it will trigger oops. If the system is configured with softlockup_panic and the same hook is repeatedly registered on the panic_notifier_list, it will cause a loop panic.

[PATCH 001/132] net: rmnet: fix lower interface leak
by Yang Yingliang 24 Jul '20

24 Jul '20

From: Taehee Yoo <ap420073(a)gmail.com> commit 2a762e9e8cd1cf1242e4269a2244666ed02eecd1 upstream. There are two types of the lower interface of rmnet that are VND and BRIDGE. Each lower interface can have only one type either VND or BRIDGE. But, there is a case, which uses both lower interface types. Due to this unexpected behavior, lower interface leak occurs. Test commands: ip link add dummy0 type dummy ip link add dummy1 type dummy ip link add rmnet0 link dummy0 type rmnet mux_id 1 ip link set dummy1 master rmnet0 ip link add rmnet1 link dummy1 type rmnet mux_id 2 ip link del rmnet0 The dummy1 was attached as BRIDGE interface of rmnet0. Then, it also was attached as VND interface of rmnet1. This is unexpected behavior and there is no code for handling this case. So that below splat occurs when the rmnet0 interface is deleted. Splat looks like: [ 53.254112][ C1] WARNING: CPU: 1 PID: 1192 at net/core/dev.c:8992 rollback_registered_many+0x986/0xcf0 [ 53.254117][ C1] Modules linked in: rmnet dummy openvswitch nsh nf_conncount nf_nat nf_conntrack nf_defrag_ipv6 nfx [ 53.254182][ C1] CPU: 1 PID: 1192 Comm: ip Not tainted 5.8.0-rc1+ #620 [ 53.254188][ C1] Hardware name: innotek GmbH VirtualBox/VirtualBox, BIOS VirtualBox 12/01/2006 [ 53.254192][ C1] RIP: 0010:rollback_registered_many+0x986/0xcf0 [ 53.254200][ C1] Code: 41 8b 4e cc 45 31 c0 31 d2 4c 89 ee 48 89 df e8 e0 47 ff ff 85 c0 0f 84 cd fc ff ff 0f 0b e5 [ 53.254205][ C1] RSP: 0018:ffff888050a5f2e0 EFLAGS: 00010287 [ 53.254214][ C1] RAX: ffff88805756d658 RBX: ffff88804d99c000 RCX: ffffffff8329d323 [ 53.254219][ C1] RDX: 1ffffffff0be6410 RSI: 0000000000000008 RDI: ffffffff85f32080 [ 53.254223][ C1] RBP: dffffc0000000000 R08: fffffbfff0be6411 R09: fffffbfff0be6411 [ 53.254228][ C1] R10: ffffffff85f32087 R11: 0000000000000001 R12: ffff888050a5f480 [ 53.254233][ C1] R13: ffff88804d99c0b8 R14: ffff888050a5f400 R15: ffff8880548ebe40 [ 53.254238][ C1] FS: 00007f6b86b370c0(0000) GS:ffff88806c200000(0000) knlGS:0000000000000000 [ 53.254243][ C1] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 53.254248][ C1] CR2: 0000562c62438758 CR3: 000000003f600005 CR4: 00000000000606e0 [ 53.254253][ C1] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 53.254257][ C1] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 53.254261][ C1] Call Trace: [ 53.254266][ C1] ? lockdep_hardirqs_on_prepare+0x379/0x540 [ 53.254270][ C1] ? netif_set_real_num_tx_queues+0x780/0x780 [ 53.254275][ C1] ? rmnet_unregister_real_device+0x56/0x90 [rmnet] [ 53.254279][ C1] ? __kasan_slab_free+0x126/0x150 [ 53.254283][ C1] ? kfree+0xdc/0x320 [ 53.254288][ C1] ? rmnet_unregister_real_device+0x56/0x90 [rmnet] [ 53.254293][ C1] unregister_netdevice_many.part.135+0x13/0x1b0 [ 53.254297][ C1] rtnl_delete_link+0xbc/0x100 [ 53.254301][ C1] ? rtnl_af_register+0xc0/0xc0 [ 53.254305][ C1] rtnl_dellink+0x2dc/0x840 [ 53.254309][ C1] ? find_held_lock+0x39/0x1d0 [ 53.254314][ C1] ? valid_fdb_dump_strict+0x620/0x620 [ 53.254318][ C1] ? rtnetlink_rcv_msg+0x457/0x890 [ 53.254322][ C1] ? lock_contended+0xd20/0xd20 [ 53.254326][ C1] rtnetlink_rcv_msg+0x4a8/0x890 [ ... ] [ 73.813696][ T1192] unregister_netdevice: waiting for rmnet0 to become free.

[PATCH] scsi: qedf: remove memset/memcpy to nfunc and use func instead
