2022-02-24mptcp: Correctly set DATA_FIN timeout when number of retransmits is largeMat Martineau
Syzkaller with UBSAN uncovered a scenario where a large number of DATA_FIN retransmits caused a shift-out-of-bounds in the DATA_FIN timeout calculation: ================================================================================ UBSAN: shift-out-of-bounds in net/mptcp/protocol.c:470:29 shift exponent 32 is too large for 32-bit type 'unsigned int' CPU: 1 PID: 13059 Comm: kworker/1:0 Not tainted 5.17.0-rc2-00630-g5fbf21c90c60 #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.13.0-1ubuntu1.1 04/01/2014 Workqueue: events mptcp_worker Call Trace: <TASK> __dump_stack lib/dump_stack.c:88 [inline] dump_stack_lvl+0xcd/0x134 lib/dump_stack.c:106 ubsan_epilogue+0xb/0x5a lib/ubsan.c:151 __ubsan_handle_shift_out_of_bounds.cold+0xb2/0x20e lib/ubsan.c:330 mptcp_set_datafin_timeout net/mptcp/protocol.c:470 [inline] __mptcp_retrans.cold+0x72/0x77 net/mptcp/protocol.c:2445 mptcp_worker+0x58a/0xa70 net/mptcp/protocol.c:2528 process_one_work+0x9df/0x16d0 kernel/workqueue.c:2307 worker_thread+0x95/0xe10 kernel/workqueue.c:2454 kthread+0x2f4/0x3b0 kernel/kthread.c:377 ret_from_fork+0x1f/0x30 arch/x86/entry/entry_64.S:295 </TASK> ================================================================================ This change limits the maximum timeout by limiting the size of the shift, which keeps all intermediate values in-bounds.

2022-02-24mptcp: accurate SIOCOUTQ for fallback socketPaolo Abeni
The MPTCP SIOCOUTQ implementation is not very accurate in case of fallback: it only measures the data in the MPTCP-level write queue, but it does not take in account the subflow write queue utilization. In case of fallback the first can be empty, while the latter is not. The above produces sporadic self-tests issues and can foul legit user-space application. Fix the issue additionally querying the subflow in case of fallback.

2022-02-24Bluetooth: fix data races in smp_unregister(), smp_del_chan()Lin Ma
Previous commit e04480920d1e ("Bluetooth: defer cleanup of resources in hci_unregister_dev()") defers all destructive actions to hci_release_dev() to prevent cocurrent problems like NPD, UAF. However, there are still some exceptions that are ignored. The smp_unregister() in hci_dev_close_sync() (previously in hci_dev_do_close) will release resources like the sensitive channel and the smp_dev objects. Consider the situations the device is detaching or power down while the kernel is still operating on it, the following data race could take place. thread-A hci_dev_close_sync | thread-B read_local_oob_ext_data | hci_dev_unlock() | ... | hci_dev_lock() if (hdev->smp_data) | chan = hdev->smp_data | | chan = hdev->smp_data (3) | hdev->smp_data = NULL (1) | if (!chan || !chan->data) (4) ... | smp = chan->data | smp = chan->data if (smp) | chan->data = NULL (2) | ... | kfree_sensitive(smp) | | // dereference smp trigger UFA That is, the objects hdev->smp_data and chan->data both suffer from the data races. In a preempt-enable kernel, the above schedule (when (3) is before (1) and (4) is before (2)) leads to UAF bugs. It can be reproduced in the latest kernel and below is part of the report: [ 49.097146] ================================================================ [ 49.097611] BUG: KASAN: use-after-free in smp_generate_oob+0x2dd/0x570 [ 49.097611] Read of size 8 at addr ffff888006528360 by task generate_oob/155 [ 49.097611] [ 49.097611] Call Trace: [ 49.097611] <TASK> [ 49.097611] dump_stack_lvl+0x34/0x44 [ 49.097611] print_address_description.constprop.0+0x1f/0x150 [ 49.097611] ? smp_generate_oob+0x2dd/0x570 [ 49.097611] ? smp_generate_oob+0x2dd/0x570 [ 49.097611] kasan_report.cold+0x7f/0x11b [ 49.097611] ? smp_generate_oob+0x2dd/0x570 [ 49.097611] smp_generate_oob+0x2dd/0x570 [ 49.097611] read_local_oob_ext_data+0x689/0xc30 [ 49.097611] ? hci_event_packet+0xc80/0xc80 [ 49.097611] ? sysvec_apic_timer_interrupt+0x9b/0xc0 [ 49.097611] ? asm_sysvec_apic_timer_interrupt+0x12/0x20 [ 49.097611] ? mgmt_init_hdev+0x1c/0x240 [ 49.097611] ? mgmt_init_hdev+0x28/0x240 [ 49.097611] hci_sock_sendmsg+0x1880/0x1e70 [ 49.097611] ? create_monitor_event+0x890/0x890 [ 49.097611] ? create_monitor_event+0x890/0x890 [ 49.097611] sock_sendmsg+0xdf/0x110 [ 49.097611] __sys_sendto+0x19e/0x270 [ 49.097611] ? __ia32_sys_getpeername+0xa0/0xa0 [ 49.097611] ? kernel_fpu_begin_mask+0x1c0/0x1c0 [ 49.097611] __x64_sys_sendto+0xd8/0x1b0 [ 49.097611] ? syscall_exit_to_user_mode+0x1d/0x40 [ 49.097611] do_syscall_64+0x3b/0x90 [ 49.097611] entry_SYSCALL_64_after_hwframe+0x44/0xae [ 49.097611] RIP: 0033:0x7f5a59f51f64 ...

That is, the smp_unregister() function can not be concurrently executed when operating functions (most of them are mgmt operations in mgmt.c) hold the device lock. This patch is tested with kernel LOCK DEBUGGING enabled. The price from the extended holding time of the device lock is supposed to be low as the smp_unregister() function is fairly short and efficient.

2022-02-24net: mv643xx_eth: process retval from of_get_mac_addressMauri Sandberg
Obtaining a MAC address may be deferred in cases when the MAC is stored in an NVMEM block, for example, and it may not be ready upon the first retrieval attempt and return EPROBE_DEFER. It is also possible that a port that does not rely on NVMEM has been already created when getting the defer request. Thus, also the resources allocated previously must be freed when doing a roll-back.

2022-02-24openvswitch: Fix setting ipv6 fields causing hw csum failurePaul Blakey

2022-02-24Revert "xen-netback: Check for hotplug-status existence before watching"Marek Marczykowski-Górecki
This reverts commit 2afeec08ab5c86ae21952151f726bfe184f6b23d. The reasoning in the commit was wrong - the code expected to setup the watch even if 'hotplug-status' didn't exist. In fact, it relied on the watch being fired the first time - to check if maybe 'hotplug-status' is already set to 'connected'. Not registering a watch for non-existing path (which is the case if hotplug script hasn't been executed yet), made the backend not waiting for the hotplug script to execute. This in turns, made the netfront think the interface is fully operational, while in fact it was not (the vif interface on xen-netback side might not be configured yet). This was a workaround for 'hotplug-status' erroneously being removed. But since that is reverted now, the workaround is not necessary either.

2022-02-24Revert "xen-netback: remove 'hotplug-status' once it has served its purpose"Marek Marczykowski-Górecki
This reverts commit 1f2565780e9b7218cf92c7630130e82dcc0fe9c2. The 'hotplug-status' node should not be removed as long as the vif device remains configured. Otherwise the xen-netback would wait for re-running the network script even if it was already called (in case of the frontent re-connecting). But also, it _should_ be removed when the vif device is destroyed (for example when unbinding the driver) - otherwise hotplug script would not configure the device whenever it re-appear. Moving removal of the 'hotplug-status' node was a workaround for nothing calling network script after xen-netback module is reloaded. But when vif interface is re-created (on xen-netback unbind/bind for example), the script should be called, regardless of who does that - currently this case is not handled by the toolstack, and requires manual script call. Keeping hotplug-status=connected to skip the call is wrong and leads to not configured interface.

2022-02-24platform/x86: amd-pmc: Set QOS during suspend on CZN w/ timer wakeupMario Limonciello
commit 59348401ebed ("platform/x86: amd-pmc: Add special handling for timer based S0i3 wakeup") adds support for using another platform timer in lieu of the RTC which doesn't work properly on some systems. This path was validated and worked well before submission. During the 5.16-rc1 merge window other patches were merged that caused this to stop working properly. When this feature was used with 5.16-rc1 or later some OEM laptops with the matching firmware requirements from that commit would shutdown instead of program a timer based wakeup. This was bisected to commit 8d89835b0467 ("PM: suspend: Do not pause cpuidle in the suspend-to-idle path"). This wasn't supposed to cause any negative impacts and also tested well on both Intel and ARM platforms. However this changed the semantics of when CPUs are allowed to be in the deepest state. For the AMD systems in question it appears this causes a firmware crash for timer based wakeup. It's hypothesized to be caused by the `amd-pmc` driver sending `OS_HINT` and all the CPUs going into a deep state while the timer is still being programmed. It's likely a firmware bug, but to avoid it don't allow setting CPUs into the deepest state while using CZN timer wakeup path. If later it's discovered that this also occurs from "regular" suspends without a timer as well or on other silicon, this may be later expanded to run in the suspend path for more scenarios.

2022-02-23net/mlx5e: kTLS, Use CHECKSUM_UNNECESSARY for device-offloaded packetsTariq Toukan
For RX TLS device-offloaded packets, the HW spec guarantees checksum validation for the offloaded packets, but does not define whether the CQE.checksum field matches the original packet (ciphertext) or the decrypted one (plaintext). This latitude allows architetctural improvements between generations of chips, resulting in different decisions regarding the value type of CQE.checksum. Hence, for these packets, the device driver should not make use of this CQE field. Here we block CHECKSUM_COMPLETE usage for RX TLS device-offloaded packets, and use CHECKSUM_UNNECESSARY instead. Value of the packet's tcp_hdr.csum is not modified by the HW, and it always matches the original ciphertext.

2022-02-23net/mlx5: DR, Fix the threshold that defines when pool sync is initiatedYevgeny Kliteynik
When deciding whether to start syncing and actually free all the "hot" ICM chunks, we need to consider the type of the ICM chunks that we're dealing with. For instance, the amount of available ICM for MODIFY_ACTION is significantly lower than the usual STE ICM, so the threshold should account for that - otherwise we can deplete MODIFY_ACTION memory just by creating and deleting the same modify header action in a continuous loop. This patch replaces the hard-coded threshold with a dynamic value.

2022-02-23net/mlx5: DR, Don't allow match on IP w/o matching on full ethertype/ip_versionYevgeny Kliteynik
Currently SMFS allows adding rule with matching on src/dst IP w/o matching on full ethertype or ip_version, which is not supported by HW. This patch fixes this issue and adds the check as it is done in DMFS.

2022-02-23net/mlx5: DR, Fix slab-out-of-bounds in mlx5_cmd_dr_create_fteYevgeny Kliteynik
When adding a rule with 32 destinations, we hit the following out-of-band access issue: BUG: KASAN: slab-out-of-bounds in mlx5_cmd_dr_create_fte+0x18ee/0x1e70 This patch fixes the issue by both increasing the allocated buffers to accommodate for the needed actions and by checking the number of actions to prevent this issue when a rule with too many actions is provided.

2022-02-23net/mlx5: DR, Cache STE shadow memoryYevgeny Kliteynik
During rule insertion on each ICM memory chunk we also allocate shadow memory used for management. This includes the hw_ste, dr_ste and miss list per entry. Since the scale of these allocations is large we noticed a performance hiccup that happens once malloc and free are stressed. In extreme usecases when ~1M chunks are freed at once, it might take up to 40 seconds to complete this, up to the point the kernel sees this as self-detected stall on CPU: rcu: INFO: rcu_sched self-detected stall on CPU To resolve this we will increase the reuse of shadow memory. Doing this we see that a time in the aforementioned usecase dropped from ~40 seconds to ~8-10 seconds.
