2022-02-03Bluetooth: MGMT: Fix misplaced BT_HS checkGuillaume Bertholon
The upstream commit b560a208cda0 ("Bluetooth: MGMT: Fix not checking if BT_HS is enabled") inserted a new check in the `set_hs` function. However, its backported version in stable (commit 5abe9f99f512 ("Bluetooth: MGMT: Fix not checking if BT_HS is enabled")), added the check in `set_link_security` instead. This patch restores the intent of the upstream commit by moving back the BT_HS check to `set_hs`.

2022-02-03ipv4: tcp: send zero IPID in SYNACK messagesEric Dumazet
[ Upstream commit 970a5a3ea86da637471d3cd04d513a0755aba4bf ] In commit 431280eebed9 ("ipv4: tcp: send zero IPID for RST and ACK sent in SYN-RECV and TIME-WAIT state") we took care of some ctl packets sent by TCP. It turns out we need to use a similar strategy for SYNACK packets. By default, they carry IP_DF and IPID==0, but there are ways to ask them to use the hashed IP ident generator and thus be used to build off-path attacks. (Ref: Off-Path TCP Exploits of the Mixed IPID Assignment) One of this way is to force (before listener is started) echo 1 >/proc/sys/net/ipv4/ip_no_pmtu_disc Another way is using forged ICMP ICMP_FRAG_NEEDED with a very small MTU (like 68) to force a false return from ip_dont_fragment() In this patch, ip_build_and_send_pkt() uses the following heuristics. 1) Most SYNACK packets are smaller than IPV4_MIN_MTU and therefore can use IP_DF regardless of the listener or route pmtu setting. 2) In case the SYNACK packet is bigger than IPV4_MIN_MTU, we use prandom_u32() generator instead of the IPv4 hashed ident one.

2022-02-03net: fix information leakage in /proc/net/ptypeCongyu Liu
commit 47934e06b65637c88a762d9c98329ae6e3238888 upstream. In one net namespace, after creating a packet socket without binding it to a device, users in other net namespaces can observe the new `packet_type` added by this packet socket by reading `/proc/net/ptype` file. This is minor information leakage as packet socket is namespace aware. Add a net pointer in `packet_type` to keep the net namespace of of corresponding packet socket. In `ptype_seq_show`, this net pointer must be checked when it is not NULL. Fixes: 2feb27dbe00c ("[NETNS]: Minor information leak via /proc/net/ptype file.")

2022-02-03can: bcm: fix UAF of bcm opZiyang Xuan
Stopping tasklet and hrtimer rely on the active state of tasklet and hrtimer sequentially in bcm_remove_op(), the op object will be freed if they are all unactive. Assume the hrtimer timeout is short, the hrtimer cb has been excuted after tasklet conditional judgment which must be false after last round tasklet_kill() and before condition hrtimer_active(), it is false when execute to hrtimer_active(). Bug is triggerd, because the stopping action is end and the op object will be freed, but the tasklet is scheduled. The resources of the op object will occur UAF bug. Move hrtimer_cancel() behind tasklet_kill() and switch 'while () {...}' to 'do {...} while ()' to fix the op UAF problem.

2022-01-27net_sched: restore "mpu xxx" handlingKevin Bracey
commit fb80445c438c78b40b547d12b8d56596ce4ccfeb upstream. commit 56b765b79e9a ("htb: improved accuracy at high rates") broke "overhead X", "linklayer atm" and "mpu X" attributes. "overhead X" and "linklayer atm" have already been fixed. This restores the "mpu X" handling, as might be used by DOCSIS or Ethernet shaping: tc class add ... htb rate X overhead 4 mpu 64 The code being fixed is used by htb, tbf and act_police. Cake has its own mpu handling. qdisc_calculate_pkt_len still uses the size table containing values adjusted for mpu by user space. iproute2 tc has always passed mpu into the kernel via a tc_ratespec structure, but the kernel never directly acted on it, merely stored it so that it could be read back by `tc class show`. Rather, tc would generate length-to-time tables that included the mpu (and linklayer) in their construction, and the kernel used those tables. Since v3.7, the tables were no longer used. Along with "mpu", this also broke "overhead" and "linklayer" which were fixed in 01cb71d2d47b ("net_sched: restore "overhead xxx" handling", v3.10) and 8a8e3d84b171 ("net_sched: restore "linklayer atm" handling", v3.11). "overhead" was fixed by simply restoring use of tc_ratespec::overhead - this had originally been used by the kernel but was initially omitted from the new non-table-based calculations. "linklayer" had been handled in the table like "mpu", but the mode was not originally passed in tc_ratespec. The new implementation was made to handle it by getting new versions of tc to pass the mode in an extended tc_ratespec, and for older versions of tc the table contents were analysed at load time to deduce linklayer. As "mpu" has always been given to the kernel in tc_ratespec, accompanying the mpu-based table, we can restore system functionality with no userspace change by making the kernel act on the tc_ratespec value.

2022-01-27netns: add schedule point in ops_exit_list()Eric Dumazet
commit 2836615aa22de55b8fca5e32fe1b27a67cda625e upstream. When under stress, cleanup_net() can have to dismantle netns in big numbers. ops_exit_list() currently calls many helpers [1] that have no schedule point, and we can end up with soft lockups, particularly on hosts with many cpus. Even for moderate amount of netns processed by cleanup_net() this patch avoids latency spikes. [1] Some of these helpers like fib_sync_up() and fib_sync_down_dev() are very slow because net/ipv4/fib_semantics.c uses host-wide hash tables, and ifindex is used as the only input of two hash functions. ifindexes tend to be the same for all netns (lo.ifindex==1 per instance) This will be fixed in a separate patch.

2022-01-27nfc: llcp: fix NULL error pointer dereference on sendmsg() after failed bind()Krzysztof Kozlowski
commit dded08927ca3c31a5c37f8e7f95fe98770475dd4 upstream. Syzbot detected a NULL pointer dereference of nfc_llcp_sock->dev pointer (which is a 'struct nfc_dev *') with calls to llcp_sock_sendmsg() after a failed llcp_sock_bind(). The message being sent is a SOCK_DGRAM. KASAN report: BUG: KASAN: null-ptr-deref in nfc_alloc_send_skb+0x2d/0xc0 Read of size 4 at addr 00000000000005c8 by task llcp_sock_nfc_a/899 CPU: 5 PID: 899 Comm: llcp_sock_nfc_a Not tainted 5.16.0-rc6-next-20211224-00001-gc6437fbf18b0 #125 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-2 04/01/2014 Call Trace: <TASK> dump_stack_lvl+0x45/0x59 ? nfc_alloc_send_skb+0x2d/0xc0 __kasan_report.cold+0x117/0x11c ? mark_lock+0x480/0x4f0 ? nfc_alloc_send_skb+0x2d/0xc0 kasan_report+0x38/0x50 nfc_alloc_send_skb+0x2d/0xc0 nfc_llcp_send_ui_frame+0x18c/0x2a0 ? nfc_llcp_send_i_frame+0x230/0x230 ? __local_bh_enable_ip+0x86/0xe0 ? llcp_sock_connect+0x470/0x470 ? llcp_sock_connect+0x470/0x470 sock_sendmsg+0x8e/0xa0 ____sys_sendmsg+0x253/0x3f0 ... The issue was visible only with multiple simultaneous calls to bind() and sendmsg(), which resulted in most of the bind() calls to fail. The bind() was failing on checking if there is available WKS/SDP/SAP (respective bit in 'struct nfc_llcp_local' fields). When there was no available WKS/SDP/SAP, the bind returned error but the sendmsg() to such socket was able to trigger mentioned NULL pointer dereference of nfc_llcp_sock->dev. The code looks simply racy and currently it protects several paths against race with checks for (!nfc_llcp_sock->local) which is NULL-ified in error paths of bind(). The llcp_sock_sendmsg() did not have such check but called function nfc_llcp_send_ui_frame() had, although not protected with lock_sock(). Therefore the race could look like (same socket is used all the time): CPU0 CPU1 ==== ==== llcp_sock_bind() - lock_sock() - success - release_sock() - return 0 llcp_sock_sendmsg() - lock_sock() - release_sock() llcp_sock_bind(), same socket - lock_sock() - error - nfc_llcp_send_ui_frame() - if (!llcp_sock->local) - llcp_sock->local = NULL - nfc_put_device(dev) - dereference llcp_sock->dev - release_sock() - return -ERRNO The nfc_llcp_send_ui_frame() checked llcp_sock->local outside of the lock, which is racy and ineffective check. Instead, its caller llcp_sock_sendmsg(), should perform the check inside lock_sock().

BUG: unable to handle page fault for address: ffffde49a863de28 PGD 7e6fe62067 P4D 7e6fe62067 PUD 7e6fe63067 PMD f51e064067 PTE 0 RIP: 0010:tw_timer_handler+0x20/0x40 Call Trace: <IRQ> call_timer_fn+0x2b/0x120 run_timer_softirq+0x1ef/0x450 __do_softirq+0x10d/0x2b8 irq_exit+0xc7/0xd0 smp_apic_timer_interrupt+0x68/0x120 apic_timer_interrupt+0xf/0x20 This issue was also reported since 2017 in the thread [1], unfortunately, the issue was still can be reproduced after fixing DCCP. The ipv4_mib_exit_net is called before tcp_sk_exit_batch when a net namespace is destroyed since tcp_sk_ops is registered befrore ipv4_mib_ops, which means tcp_sk_ops is in the front of ipv4_mib_ops in the list of pernet_list. There will be a use-after-free on net->mib.net_statistics in tw_timer_handler after ipv4_mib_exit_net if there are some inflight time-wait timers. This bug is not introduced by commit f2bf415cfed7 ("mib: add net to NET_ADD_STATS_BH") since the net_statistics is a global variable instead of dynamic allocation and freeing. Actually, commit 61a7e26028b9 ("mib: put net statistics on struct net") introduces the bug since it put net statistics on struct net and free it when net namespace is destroyed. Moving init_ipv4_mibs() to the front of tcp_init() to fix this bug and replace pr_crit() with panic() since continuing is meaningless when init_ipv4_mibs() fails.

commit 75a2f31520095600f650597c0ac41f48b5ba0068 upstream. This ioctl() implicitly assumed that the socket was already bound to a valid local socket name, i.e. Phonet object. If the socket was not bound, two separate problems would occur: 1) We'd send an pipe enablement request with an invalid source object. 2) Later socket calls could BUG on the socket unexpectedly being connected yet not bound to a valid object.

2021-12-29ax25: NPD bug when detaching AX25 deviceLin Ma
commit 1ade48d0c27d5da1ccf4b583d8c5fc8b534a3ac8 upstream. The existing cleanup routine implementation is not well synchronized with the syscall routine. When a device is detaching, below race could occur. static int ax25_sendmsg(...) { ... lock_sock() ax25 = sk_to_ax25(sk); if (ax25->ax25_dev == NULL) // CHECK ... ax25_queue_xmit(skb, ax25->ax25_dev->dev); // USE ... } static void ax25_kill_by_device(...) { ... if (s->ax25_dev == ax25_dev) { s->ax25_dev = NULL; ... } Other syscall functions like ax25_getsockopt, ax25_getname, ax25_info_show also suffer from similar races. To fix them, this patch introduce lock_sock() into ax25_kill_by_device in order to guarantee that the nullify action in cleanup routine cannot proceed when another socket request is pending.

2021-12-22mac80211: send ADDBA requests using the tid/queue of the aggregation sessionFelix Fietkau
commit 1fe98f5690c4219d419ea9cc190f94b3401cf324 upstream. Sending them out on a different queue can cause a race condition where a number of packets in the queue may be discarded by the receiver, because the ADDBA request is sent too early. This affects any driver with software A-MPDU setup which does not allocate packet seqno in hardware on tx, regardless of whether iTXQ is used or not. The only driver I've seen that explicitly deals with this issue internally is mwl8k.

2021-12-22net: netlink: af_netlink: Prevent empty skb by adding a check on len.Harshit Mogalapalli
[ Upstream commit f123cffdd8fe8ea6c7fded4b88516a42798797d0 ] Adding a check on len parameter to avoid empty skb. This prevents a division error in netem_enqueue function which is caused when skb->len=0 and skb->data_len=0 in the randomized corruption step as shown below. skb->data[prandom_u32() % skb_headlen(skb)] ^= 1<<(prandom_u32() % 8); Crash Report: [ 343.170349] netdevsim netdevsim0 netdevsim3: set [1, 0] type 2 family 0 port 6081 - 0 [ 343.216110] netem: version 1.3 [ 343.235841] divide error: 0000 [#1] PREEMPT SMP KASAN NOPTI [ 343.236680] CPU: 3 PID: 4288 Comm: reproducer Not tainted 5.16.0-rc1+ [ 343.237569] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.11.0-2.el7 04/01/2014 [ 343.238707] RIP: 0010:netem_enqueue+0x1590/0x33c0 [sch_netem] [ 343.239499] Code: 89 85 58 ff ff ff e8 5f 5d e9 d3 48 8b b5 48 ff ff ff 8b 8d 50 ff ff ff 8b 85 58 ff ff ff 48 8b bd 70 ff ff ff 31 d2 2b 4f 74 <f7> f1 48 b8 00 00 00 00 00 fc ff df 49 01 d5 4c 89 e9 48 c1 e9 03 [ 343.241883] RSP: 0018:ffff88800bcd7368 EFLAGS: 00010246 [ 343.242589] RAX: 00000000ba7c0a9c RBX: 0000000000000001 RCX: 0000000000000000 [ 343.243542] RDX: 0000000000000000 RSI: ffff88800f8edb10 RDI: ffff88800f8eda40 [ 343.244474] RBP: ffff88800bcd7458 R08: 0000000000000000 R09: ffffffff94fb8445 [ 343.245403] R10: ffffffff94fb8336 R11: ffffffff94fb8445 R12: 0000000000000000 [ 343.246355] R13: ffff88800a5a7000 R14: ffff88800a5b5800 R15: 0000000000000020 [ 343.247291] FS: 00007fdde2bd7700(0000) GS:ffff888109780000(0000) knlGS:0000000000000000 [ 343.248350] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 343.249120] CR2: 00000000200000c0 CR3: 000000000ef4c000 CR4: 00000000000006e0 [ 343.250076] Call Trace: [ 343.250423] <TASK> [ 343.250713] ?

2021-12-14HID: introduce hid_is_using_ll_driverJason Gerecke
commit fc2237a724a9e448599076d7d23497f51e2f7441 upstream. Although HID itself is transport-agnostic, occasionally a driver may want to interact with the low-level transport that a device is connected through. To do this, we need to know what kind of bus is in use. The first guess may be to look at the 'bus' field of the 'struct hid_device', but this field may be emulated in some cases (e.g. uhid). More ideally, we can check which ll_driver a device is using. This function introduces a 'hid_is_using_ll_driver' function and makes the 'struct hid_ll_driver' of the four most common transports accessible through hid.h.

2021-12-08NFC: add NCI_UNREG flag to eliminate the raceLin Ma
commit 48b71a9e66c2eab60564b1b1c85f4928ed04e406 upstream. There are two sites that calls queue_work() after the destroy_workqueue() and lead to possible UAF. The first site is nci_send_cmd(), which can happen after the nci_close_device as below nfcmrvl_nci_unregister_dev | nfc_genl_dev_up nci_close_device | flush_workqueue | del_timer_sync | nci_unregister_device | nfc_get_device destroy_workqueue | nfc_dev_up nfc_unregister_device | nci_dev_up device_del | nci_open_device | __nci_request | nci_send_cmd | queue_work !!! Another site is nci_cmd_timer, awaked by the nci_cmd_work from the nci_send_cmd. ... | ... nci_unregister_device | queue_work destroy_workqueue | nfc_unregister_device | ... device_del | nci_cmd_work | mod_timer | ... | nci_cmd_timer | queue_work !!! For the above two UAF, the root cause is that the nfc_dev_up can race between the nci_unregister_device routine. Therefore, this patch introduce NCI_UNREG flag to easily eliminate the possible race. In addition, the mutex_lock in nci_close_device can act as a barrier.

2021-12-08tcp_cubic: fix spurious Hystart ACK train detections for not-cwnd-limited flowsEric Dumazet
[ Upstream commit 4e1fddc98d2585ddd4792b5e44433dcee7ece001 ] While testing BIG TCP patch series, I was expecting that TCP_RR workloads with 80KB requests/answers would send one 80KB TSO packet, then being received as a single GRO packet. It turns out this was not happening, and the root cause was that cubic Hystart ACK train was triggering after a few (2 or 3) rounds of RPC. Hystart was wrongly setting CWND/SSTHRESH to 30, while my RPC needed a budget of ~20 segments. Ideally these TCP_RR flows should not exit slow start. Cubic Hystart should reset itself at each round, instead of assuming every TCP flow is a bulk one. Note that even after this patch, Hystart can still trigger, depending on scheduling artifacts, but at a higher CWND/SSTHRESH threshold, keeping optimal TSO packet sizes.

2021-11-26batman-adv: Avoid WARN_ON timing related checksSven Eckelmann
commit 9f460ae31c4435fd022c443a6029352217a16ac1 upstream. The soft/batadv interface for a queued OGM can be changed during the time the OGM was queued for transmission and when the OGM is actually transmitted by the worker. But WARN_ON must be used to denote kernel bugs and not to print simple warnings. A warning can simply be printed using pr_warn.

2021-11-26batman-adv: Don't always reallocate the fragmentation skb headSven Eckelmann
commit 992b03b88e36254e26e9a4977ab948683e21bd9f upstream. When a packet is fragmented by batman-adv, the original batman-adv header is not modified. Only a new fragmentation is inserted between the original one and the ethernet header. The code must therefore make sure that it has a writable region of this size in the skbuff head. But it is not useful to always reallocate the skbuff by this size even when there would be more than enough headroom still in the skb. The reallocation is just to costly during in this codepath.

2021-11-26batman-adv: Reserve needed_*room for fragmentsSven Eckelmann
commit c5cbfc87558168ef4c3c27ce36eba6b83391db19 upstream. The batadv net_device is trying to propagate the needed_headroom and needed_tailroom from the lower devices. This is needed to avoid cost intensive reallocations using pskb_expand_head during the transmission. But the fragmentation code split the skb's without adding extra room at the end/beginning of the various fragments. This reduced the performance of transmissions over complex scenarios (batadv on vxlan on wireguard) because the lower devices had to perform the reallocations at least once.

2021-11-26batman-adv: Consider fragmentation for needed_headroomSven Eckelmann
commit 4ca23e2c2074465bff55ea14221175fecdf63c5f upstream. If a batman-adv packets has to be fragmented, then the original batman-adv packet header is not stripped away. Instead, only a new header is added in front of the packet after it was split. This size must be considered to avoid cost intensive reallocations during the transmission through the various device layers.
