commit eea0d3ea upstream. During freeing of the internal buffers used by the DRBG, set the pointer to NULL. It is possible that the context with the freed buffers is reused. In case of an error during initialization where the pointers do not yet point to allocated memory, the NULL value prevents a double free.

commit d2ffed51 upstream. When printing the driver_override parameter when it is 4095 and 4094 bytes long, the printing code would access invalid memory because we need count + 1 bytes for printing. Cfr. commits 4efe874a ("PCI: Don't read past the end of sysfs "driver_override" buffer") and bf563b01 ("driver core: platform: Don't read past the end of "driver_override" buffer").

commit 6a7228d9 upstream. The driver_override implementation is susceptible to a race condition when different threads are reading vs storing a different driver override. Add locking to avoid this race condition. Cfr. commits 62655397 ("driver core: platform: fix race condition with driver_override") and 9561475d ("PCI: Fix race condition with driver_override").

commit 5f536246 upstream. For AMBA devices with unconfigured driver override, the "driver_override" sysfs virtual file is empty, while it contains "(null)" for platform and PCI devices. Make AMBA consistent with other buses by dropping the test for a NULL pointer. Note that contrary to popular belief, sprintf() handles NULL pointers fine; they are printed as "(null)". Signed-off-by:

commit fc31c4e3 upstream. There is an obvious typo issue in the definition of the PCIe maximum read request size: a bit shift is directly used as a value, while it should be used to shift the correct value.

commit 660661af upstream. The PCI configuration space read/write functions were special casing the situation where PCI_SLOT(devfn) != 0, and returned PCIBIOS_DEVICE_NOT_FOUND in this case. However, while this is what is intended for the root bus, it is not intended for the child busses, as it prevents discovering devices with PCI_SLOT(x) != 0. Therefore, we return PCIBIOS_DEVICE_NOT_FOUND only if we're on the root bus. Fixes: 8c39d710 ("PCI: aardvark: Add Aardvark PCI host controller driver") Cc: <stable@vger.kernel.org> Signed-off-by:

commit 69fa6f19 upstream. As recently Smatch suggested, one place in HD-audio hwdep ioctl codes may expand the array directly from the user-space value with speculation: sound/pci/hda/hda_local.h:467 get_wcaps() warn: potential spectre issue 'codec->wcaps' As get_wcaps() itself is a fairly frequently called inline function, and there is only one single call with a user-space value, we replace only the latter one to open-code locally with array_index_nospec() hardening in this patch.

commit 8d218dd8 upstream. As Smatch recently suggested, a few places in OSS sequencer codes may expand the array directly from the user-space value with speculation, namely there are a significant amount of references to either info->ch[] or dp->synths[] array: sound/core/seq/oss/seq_oss_event.c:315 note_on_event() warn: potential spectre issue 'info->ch' (local cap) sound/core/seq/oss/seq_oss_event.c:362 note_off_event() warn: potential spectre issue 'info->ch' (local cap) sound/core/seq/oss/seq_oss_synth.c:470 snd_seq_oss_synth_load_patch() warn: potential spectre issue 'dp->synths' (local cap) sound/core/seq/oss/seq_oss_event.c:293 note_on_event() warn: potential spectre issue 'dp->synths' sound/core/seq/oss/seq_oss_event.c:353 note_off_event() warn: potential spectre issue 'dp->synths' sound/core/seq/oss/seq_oss_synth.c:506 snd_seq_oss_synth_sysex() warn: potential spectre issue 'dp->synths' sound/core/seq/oss/seq_oss_synth.c:580 snd_seq_oss_synth_ioctl() warn: potential spectre issue 'dp->synths' Although all these seem doing only the first load without further reference, we may want to stay in a safer side, so hardening with array_index_nospec() would still make sense. We may put array_index_nospec() at each place, but here we take a different approach: - For dp->synths[], change the helpers to retrieve seq_oss_synthinfo pointer directly instead of the array expansion at each place - For info->ch[], harden in a normal way, as there are only a couple of places As a result, the existing helper, snd_seq_oss_synth_is_valid() is replaced with snd_seq_oss_synth_info(). Also, we cover MIDI device where a similar array expansion is done, too, although it wasn't reported by Smatch. BugLink: https://marc.info/?l=linux-kernel&m=152411496503418&w=2Reported-by:

commit f5e94b4c upstream. When get_synthdev() is called for a MIDI device, it returns the fixed midi_synth_dev without the use refcounting. OTOH, the caller is supposed to unreference unconditionally after the usage, so this would lead to unbalanced refcount. This patch corrects the behavior and keep up the refcount balance also for the MIDI synth device. Cc: <stable@vger.kernel.org> Signed-off-by:

In this patch, we put array_index_nospec() to the common snd_ctl_get_ioff*() helpers instead of each caller. These helpers are also referred from some drivers, too, and basically all usages are to calculate the array index from the user-space value, hence it's better to cover there.

commit bcdd0ca8 upstream. syzbot is reporting crashes triggered by memory allocation fault injection at tty_ldisc_get() [1]. As an attempt to handle OOM in a graceful way, we have tried commit 5362544b ("tty: don't panic on OOM in tty_set_ldisc()"). But we reverted that attempt by commit a8983d01 ("Revert "tty: don't panic on OOM in tty_set_ldisc()"") due to reproducible crash. We should spend resource for finding and fixing race condition bugs rather than complicate error paths for 2 * sizeof(void *) bytes allocation failure.

commit b2d89ad9 upstream. At least on droid 4 with control channel in ADM mode, there is no response to Modem Status Command (MSC). Currently gsmtty_modem_update() expects to have data in dlci->modem_rx unless debug & 2 is set. This means that on droid 4, things only work if debug & 2 is set. Let's fix the issue by ignoring empty dlci->modem_rx for ADM mode. In the AMD mode, CMD_MSC will never respond and gsm_process_modem() won't get called to set dlci->modem_rx. And according to ts_127010v140000p.pdf, MSC is only relevant if basic option is chosen, so let's test for that too.

commit e9ec2254 upstream. Commit ea3d8465 ("tty: n_gsm: Allow ADM response in addition to UA for control dlci") added support for DLCI to stay in Asynchronous Disconnected Mode (ADM). But we still get long delays waiting for commands to other DLCI to complete: --> 5) C: SABM(P) Q> 0) C: UIH(F) Q> 0) C: UIH(F) Q> 0) C: UIH(F) ... This happens because gsm_control_send() sets cretries timer to T2 that is by default set to 34. This will cause resend for T2 times for the control frame. In ADM mode, we will never get a response so the control frame, so retries are just delaying all the commands. Let's fix the issue by setting DLCI_MODE_ADM flag after detecting the ADM mode for the control DLCI. Then we can use that in gsm_control_send() to set retries to 1. This means the control frame will be sent once allowing the other end at an opportunity to switch from ADM to ABM mode. Note that retries will be decremented in gsm_control_retransmit() so we don't want to set it to 0 here.

commit a7a69ec0 upstream. Console driver is out of spec. The spec says: A driver MUST NOT decrement the available idx on a live virtqueue (ie. there is no way to “unexpose” buffers). and it does exactly that by trying to detach unused buffers without doing a device reset first. Defer detaching the buffers until device unplug. Of course this means we might get an interrupt for a vq without an attached port now. Handle that by discarding the consumed buffer. Reported-by:

commit 83a62c51 upstream. On chromebooks we depend on wakeup count to identify the wakeup source. But currently USB devices do not increment the wakeup count when they trigger the remote wake. This patch addresses the same. Resume condition is reported differently on USB 2.0 and USB 3.0 devices. On USB 2.0 devices, a wake capable device, if wake enabled, drives resume signal to indicate a remote wake (USB 2.0 spec section 7.1.7.7). The upstream facing port then sets C_PORT_SUSPEND bit and reports a port change event (USB 2.0 spec section 11.24.2.7.2.3). Thus if a port has resumed before driving the resume signal from the host and C_PORT_SUSPEND is set, then the device attached to the given port might be the reason for the last system wakeup. Increment the wakeup count for the same. On USB 3.0 devices, a function may signal that it wants to exit from device suspend by sending a Function Wake Device Notification to the host (USB3.0 spec section 8.5.6.4) Thus on receiving the Function Wake, increment the wakeup count.
