2022-01-16media: Revert "media: uvcvideo: Set unique vdev name based in type"Ricardo Ribalda1-6/+1
commit f66dcb32af19faf49cc4a9222c3152b10c6ec84a upstream. A lot of userspace depends on a descriptive name for vdev. Without this patch, users have a hard time figuring out which camera shall they use for their video conferencing. This reverts commit e3f60e7e1a2b451f538f9926763432249bcf39c4.

2022-01-16random: fix crash on multiple early calls to add_bootloader_randomness()Dominik Brodowski1-20/+36
commit f7e67b8e803185d0aabe7f29d25a35c8be724a78 upstream. Currently, if CONFIG_RANDOM_TRUST_BOOTLOADER is enabled, multiple calls to add_bootloader_randomness() are broken and can cause a NULL pointer dereference, as noted by Ivan T. Ivanov. This is not only a hypothetical problem, as qemu on arm64 may provide bootloader entropy via EFI and via devicetree. On the first call to add_hwgenerator_randomness(), crng_fast_load() is executed, and if the seed is long enough, crng_init will be set to 1. On subsequent calls to add_bootloader_randomness() and then to add_hwgenerator_randomness(), crng_fast_load() will be skipped. Instead, wait_event_interruptible() and then credit_entropy_bits() will be called. If the entropy count for that second seed is large enough, that proceeds to crng_reseed(). However, both wait_event_interruptible() and crng_reseed() depends (at least in numa_crng_init()) on workqueues. Therefore, test whether system_wq is already initialized, which is a sufficient indicator that workqueue_init_early() has progressed far enough. If we wind up hitting the !system_wq case, we later want to do what would have been done there when wqs are up, so set a flag, and do that work later from the rand_initialize() call.

2022-01-16random: fix data race on crng init timeEric Biggers1-7/+10
commit 009ba8568be497c640cab7571f7bfd18345d7b24 upstream. _extract_crng() does plain loads of crng->init_time and crng_global_init_time, which causes undefined behavior if crng_reseed() and RNDRESEEDCRNG modify these corrently. Use READ_ONCE() and WRITE_ONCE() to make the behavior defined. Don't fix the race on crng->init_time by protecting it with crng->lock, since it's not a problem for duplicate reseedings to occur. I.e., the lockless access with READ_ONCE() is fine.

2022-01-16random: fix data race on crng_node_poolEric Biggers1-20/+22
commit 5d73d1e320c3fd94ea15ba5f79301da9a8bcc7de upstream. extract_crng() and crng_backtrack_protect() load crng_node_pool with a plain load, which causes undefined behavior if do_numa_crng_init() modifies it concurrently. Fix this by using READ_ONCE(). Note: as per the previous discussion https://lore.kernel.org/lkml/20211219025139.31085-1-ebiggers@kernel.org/T/#u, READ_ONCE() is believed to be sufficient here, and it was requested that it be used here instead of smp_load_acquire(). Also change do_numa_crng_init() to set crng_node_pool using cmpxchg_release() instead of mb() + cmpxchg(), as the former is sufficient here but is more lightweight.

2022-01-16veth: Do not record rx queue hint in veth_xmitDaniel Borkmann1-1/+0
commit 710ad98c363a66a0cd8526465426c5c5f8377ee0 upstream. Laurent reported that they have seen a significant amount of TCP retransmissions at high throughput from applications residing in network namespaces talking to the outside world via veths. The drops were seen on the qdisc layer (fq_codel, as per systemd default) of the phys device such as ena or virtio_net due to all traffic hitting a _single_ TX queue _despite_ multi-queue device. (Note that the setup was _not_ using XDP on veths as the issue is generic.) More specifically, after edbea9220251 ("veth: Store queue_mapping independently of XDP prog presence") which made it all the way back to v4.19.184+, skb_record_rx_queue() would set skb->queue_mapping to 1 (given 1 RX and 1 TX queue by default for veths) instead of leaving at 0. This is eventually retained and callbacks like ena_select_queue() will also pick single queue via netdev_core_pick_tx()'s ndo_select_queue() once all the traffic is forwarded to that device via upper stack or other means. Similarly, for others not implementing ndo_select_queue() if XPS is disabled, netdev_pick_tx() might call into the skb_tx_hash() and check for prior skb_rx_queue_recorded() as well. In general, it is a _bad_ idea for virtual devices like veth to mess around with queue selection [by default]. Given dev->real_num_tx_queues is by default 1, the skb->queue_mapping was left untouched, and so prior to edbea9220251 the netdev_core_pick_tx() could do its job upon __dev_queue_xmit() on the phys device. Unbreak this and restore prior behavior by removing the skb_record_rx_queue() from veth_xmit() altogether. If the veth peer has an XDP program attached, then it would return the first RX queue index in xdp_md->rx_queue_index (unless configured in non-default manner). However, this is still better than breaking the generic case.

2022-01-16ath11k: Fix buffer overflow when scanning with extraieSven Eckelmann1-3/+3
commit a658c929ded7ea3aee324c8c2a9635a5e5a38e7f upstream. If cfg80211 is providing extraie's for a scanning process then ath11k will copy that over to the firmware. The extraie.len is a 32 bit value in struct element_info and describes the amount of bytes for the vendor information elements. The WMI_TLV packet is having a special WMI_TAG_ARRAY_BYTE section. This section can have a (payload) length up to 65535 bytes because the WMI_TLV_LEN can store up to 16 bits. The code was missing such a check and could have created a scan request which cannot be parsed correctly by the firmware. But the bigger problem was the allocation of the buffer. It has to align the TLV sections by 4 bytes. But the code was using an u8 to store the newly calculated length of this section (with alignment). And the new calculated length was then used to allocate the skbuff. But the actual code to copy in the data is using the extraie.len and not the calculated "aligned" length. The length of extraie with IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS enabled was 264 bytes during tests with a QCA Milan card. But it only allocated 8 bytes (264 bytes % 256) for it. As consequence, the code to memcpy the extraie into the skb was then just overwriting data after skb->end. Things like shinfo were therefore corrupted. This could usually be seen by a crash in skb_zcopy_clear which tried to call a ubuf_info callback (using a bogus address).

2022-01-16USB: Fix "slab-out-of-bounds Write" bug in usb_hcd_poll_rh_statusAlan Stern1-1/+8
commit 1d7d4c07932e04355d6e6528d44a2f2c9e354346 upstream. When the USB core code for getting root-hub status reports was originally written, it was assumed that the hub driver would be its only caller. But this isn't true now; user programs can use usbfs to communicate with root hubs and get status reports. When they do this, they may use a transfer_buffer that is smaller than the data returned by the HCD, which will lead to a buffer overflow error when usb_hcd_poll_rh_status() tries to store the status data. This was discovered by syzbot: BUG: KASAN: slab-out-of-bounds in memcpy include/linux/fortify-string.h:225 [inline] BUG: KASAN: slab-out-of-bounds in usb_hcd_poll_rh_status+0x5f4/0x780 drivers/usb/core/hcd.c:776 Write of size 2 at addr ffff88801da403c0 by task syz-executor133/4062 This patch fixes the bug by reducing the amount of status data if it won't fit in the transfer_buffer. If some data gets discarded then the URB's completion status is set to -EOVERFLOW rather than 0, to let the user know what happened.

2022-01-16USB: core: Fix bug in resuming hub's handling of wakeup requestsAlan Stern1-1/+1
commit 0f663729bb4afc92a9986b66131ebd5b8a9254d1 upstream. Bugzilla #213839 reports a 7-port hub that doesn't work properly when devices are plugged into some of the ports; the kernel goes into an unending disconnect/reinitialize loop as shown in the bug report. This "7-port hub" comprises two four-port hubs with one plugged into the other; the failures occur when a device is plugged into one of the downstream hub's ports. (These hubs have other problems too. For example, they bill themselves as USB-2.0 compliant but they only run at full speed.) It turns out that the failures are caused by bugs in both the kernel and the hub. The hub's bug is that it reports a different bmAttributes value in its configuration descriptor following a remote wakeup (0xe0 before, 0xc0 after -- the wakeup-support bit has changed). The kernel's bug is inside the hub driver's resume handler. When hub_activate() sees that one of the hub's downstream ports got a wakeup request from a child device, it notes this fact by setting the corresponding bit in the hub->change_bits variable. But this variable is meant for connection changes, not wakeup events; setting it causes the driver to believe the downstream port has been disconnected and then connected again (in addition to having received a wakeup request). Because of this, the hub driver then tries to check whether the device currently plugged into the downstream port is the same as the device that had been attached there before. Normally this check succeeds and wakeup handling continues with no harm done (which is why the bug remained undetected until now). But with these dodgy hubs, the check fails because the config descriptor has changed. This causes the hub driver to reinitialize the child device, leading to the disconnect/reinitialize loop described in the bug report. The proper way to note reception of a downstream wakeup request is to set a bit in the hub->event_bits variable instead of hub->change_bits. That way the hub driver will realize that something has happened to the port but will not think the port and child device have been disconnected. This patch makes that change.

commit 9d36de31130542fc060f7cd17e72db670202c682 upstream. When the driver is unloaded or when the system goes into standby mode, DeInitLed871x is called to stop the led layer. In this case, we stop the blinking worker but we do not switch the led off explicitly. On my system, I can go into standby mode with the LED enabled. Add a call to SwLedOff to fix this.

2022-01-14tpm: tpm_tis: Verify TPM_STS register is valid after locality requestAmir Mizinski1-1/+5
An invalid TPM_STS value could be used when the following two events occur: TPM does not update TPM_STS register after a locality request (TPM_STS Initial value = 0xFF), and a TPM_STS register read occurs in the tpm_tis_status(chip) function call. In probe_itpm(), a call to tpm_tis_send_data() function is made after a request_locality() call, and the condition ("if ((status & TPM_STS_COMMAND_READY) == 0)") is checked. At this moment if the status value is 0xFF, then it is considered, wrongly, in “ready” state (by checking only one bit). However, at this moment the TPM is, in fact, in "Idle" state and remains in "Idle" state because "tpm_tis_ready(chip);" was not executed. Waiting for the condition TPM_STS.tpmGo == 0, will ensure that the TPM status register has the correct value.

2022-01-14tpm: tpm_tis: Rewrite "tpm_tis_req_canceled()"Amir Mizinski1-4/+1
tpm_tis_req_canceled() function is used to check if the caller requested to abort the current operation. It was found that in some cases tpm_tis_req_canceled() wrongly returned true. Since a cancel request sets the TPM_STS.commandReady field to TRUE, the tpm_tis_req_canceled() function should check only the TPM_STS.commandReady field value. The case for TPM_VID_WINBOND is wrong and was therefore removed. Also, the default comparison is wrong. Only cmdReady bit needs to be compared instead of the full lower status register byte.

2022-01-14tpm_tis: Fix expected bit handlingAmir Mizinski1-34/+27
Currently, the driver polls the TPM_STS.stsValid field until TRUE; then it reads TPM_STS register again to verify only that TPM_STS.expect field is FALSE (i.e., it ignores TPM_STS.stsValid). Since TPM_STS.stsValid represents the TPM_STS.expect validity, a check of only one of these fields is wrong. Fix this condition so that both fields are checked in the same TPM_STS register read. Modify the signature of wait_for_tpm_stat() to tpm_tis_wait_for_stat(), adding an additional "expected" parameter to its call. tpm_tis_wait_for_stat() is now polling the TPM_STS with a mask and waits for the value in "expected". This modification adds the ability to check if certain TPM_STS bits have been cleared. For example, use the new parameter to check in status that TPM_STS_VALID is set and also that TPM_STS_EXPECT is zeroed. This prevents a racy check.
