intel_psr2_config_valid() fails If any of the PSR2 checks after intel_psr2_sel_fetch_config_valid() fails, enable_psr2_sel_fetch will be kept enabled causing problems in the functions that only checks for it and not for has_psr2.

2022-04-19drm/msm: Revert "drm/msm: Stop using iommu_present()"Dmitry Baryshkov1-1/+1
This reverts commit e2a88eabb02410267519b838fb9b79f5206769be. The commit in question makes msm_use_mmu() check whether the DRM 'component master' device is translated by the IOMMU. At this moment it is the 'mdss' device. However on platforms using the MDP5 driver (e.g. MSM8916/APQ8016, MSM8996/APQ8096) it's the mdp5 device, which has the iommus property (and thus is "translated by the IOMMU"). This results in these devices being broken with the following lines in the dmesg. [drm] Initialized msm 1.9.0 20130625 for 1a00000.mdss on minor 0 msm 1a00000.mdss: [drm:adreno_request_fw] loaded qcom/a300_pm4.fw from new location msm 1a00000.mdss: [drm:adreno_request_fw] loaded qcom/a300_pfp.fw from new location msm 1a00000.mdss: [drm:get_pages] *ERROR* could not get pages: -28 msm 1a00000.mdss: could not allocate stolen bo msm 1a00000.mdss: [drm:get_pages] *ERROR* could not get pages: -28 msm 1a00000.mdss: [drm:msm_alloc_stolen_fb] *ERROR* failed to allocate buffer object msm 1a00000.mdss: [drm:msm_fbdev_create] *ERROR* failed to allocate fb Getting the mdp5 device pointer from this function is not that easy at this moment. Thus this patch is reverted till the MDSS rework [1] lands. It will make the mdp5/dpu1 device component master and the check will be legit.

2022-04-19bcache: fix wrong bdev parameter when calling bio_alloc_clone() in do_bio_hook()Coly Li1-1/+1
Commit abfc426d1b2f ("block: pass a block_device to bio_clone_fast") calls the modified bio_alloc_clone() in bcache code as: bio_init_clone(bio->bi_bdev, bio, orig_bio, GFP_NOIO); But the first parameter is wrong, where bio->bi_bdev should be orig_bio->bi_bdev. The wrong bi_bdev panics the kernel when submitting cache bio. This patch fixes the wrong bdev parameter usage and avoid the panic.

2022-04-19bcache: put bch_bio_map() back to correct location in journal_write_unlocked()Coly Li1-1/+1
Commit a7c50c940477 ("block: pass a block_device and opf to bio_reset") moves bch_bio_map() inside journal_write_unlocked() next to the location where the modified bio_reset() was called. This change is wrong because calling bch_bio_map() immediately after bio_reset(), a BUG_ON(!bio->bi_iter.bi_size) inside bch_bio_map() will be triggered and panic the kernel. This patch puts bch_bio_map() back to its original correct location in journal_write_unlocked() and avoid the BUG_ON().

During the uvcg_video_pump() process, if an error occurs and uvcg_queue_cancel() is called, the buffer queue will be cleared out, but the current marker (queue->buf_used) of the active buffer (no longer active) is not reset. On the next iteration of uvcg_video_pump() the stale buf_used count will be used and the logic of min((unsigned int)len, buf->bytesused - queue->buf_used) may incorrectly calculate a nbytes size, causing an invalid memory access.

When the user runs: bridge link set dev $br_port mcast_flood on this command should affect not only L2 multicast, but also IPv4 and IPv6 multicast. In the Ocelot switch, unknown multicast gets flooded according to different PGIDs according to its type, and PGID_MC only handles L2 multicast. Therefore, by leaving PGID_MCIPV4 and PGID_MCIPV6 at their default value of 0, unknown IP multicast traffic is never flooded.

2022-04-19drm/i915/display/vrr: Reset VRR capable property on a long hpdManasi Navare1-6/+11
With some VRR panels, user can turn VRR ON/OFF on the fly from the panel settings. When VRR is turned OFF ,sends a long HPD to the driver clearing the Ignore MSA bit in the DPCD. Currently the driver parses that onevery HPD but fails to reset the corresponding VRR Capable Connector property. Hence the userspace still sees this as VRR Capable panel which is incorrect. Fix this by explicitly resetting the connector property. v2: Reset vrr capable if status == connector_disconnected v3: Use i915 and use bool vrr_capable (Jani Nikula) v4: Move vrr_capable to after update modes call (Jani N) Remove the redundant comment (Jan N) v5: Fixes the regression on older platforms by resetting the VRR only if HAS_VRR v6: Remove the checks from driver, add in drm core before setting VRR prop (Ville) v7: Move VRR set/reset to set/unset_edid (Ville) Cc: Jani Nikula <[email protected]> Cc: Ville Syrjälä <[email protected]> Fixes: 9bc34b4d0f3c ("drm/i915/display/vrr: Reset VRR capable property on a long hpd") Signed-off-by: Manasi Navare <[email protected]> Reviewed-by: Ville Syrjälä <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] (cherry picked from commit d999ad1079f574be06a8f1701cd24a5dc0ada48c) Signed-off-by: Joonas Lahtinen <[email protected]>

2022-04-18net: atlantic: invert deep par in pm functions, preventing null derefsManuel Ullmann1-4/+4
This will reset deeply on freeze and thaw instead of suspend and resume and prevent null pointer dereferences of the uninitialized ring 0 buffer while thawing. The impact is an indefinitely hanging kernel. You can't switch consoles after this and the only possible user interaction is SysRq. BUG: kernel NULL pointer dereference RIP: 0010:aq_ring_rx_fill+0xcf/0x210 [atlantic] aq_vec_init+0x85/0xe0 [atlantic] aq_nic_init+0xf7/0x1d0 [atlantic] atl_resume_common+0x4f/0x100 [atlantic] pci_pm_thaw+0x42/0xa0 resolves in aq_ring.o to ``` 0000000000000ae0 <aq_ring_rx_fill>: { /* ... */ baf: 48 8b 43 08 mov 0x8(%rbx),%rax buff->flags = 0U; /* buff is NULL */ ``` The bug has been present since the introduction of the new pm code in 8aaa112a57c1 ("net: atlantic: refactoring pm logic") and was hidden until 8ce84271697a ("net: atlantic: changes for multi-TC support"), which refactored the aq_vec_{free,alloc} functions into aq_vec_{,ring}_{free,alloc}, but is technically not wrong. The original functions just always reinitialized the buffers on S3/S4. If the interface is down before freezing, the bug does not occur. It does not matter, whether the initrd contains and loads the module before thawing. So the fix is to invert the boolean parameter deep in all pm function calls, which was clearly intended to be set like that. First report was on Github [1], which you have to guess from the resume logs in the posted dmesg snippet.

2022-04-16random: use memmove instead of memcpy for remaining 32 bytesJason A. Donenfeld1-1/+1
In order to immediately overwrite the old key on the stack, before servicing a userspace request for bytes, we use the remaining 32 bytes of block 0 as the key. This means moving indices 8,9,a,b,c,d,e,f -> 4,5,6,7,8,9,a,b. Since 4 < 8, for the kernel implementations of memcpy(), this doesn't actually appear to be a problem in practice. But relying on that characteristic seems a bit brittle. So let's change that to a proper memmove(), which is the by-the-books way of handling overlapping memory copies.

MX7ULP, MX8Q, MX8X are not affected. MX53 and older status is unknown, as the errata first appears in MX6 errata sheets from 2016 and the latest errata sheet for MX53 is from 2015. Older SoC errata sheets predate the MX53 errata sheet. MX8ULP and MX9 status is unknown as the errata sheet is not available yet. " ERR007805 I2C: When the I2C clock speed is configured for 400 kHz, the SCL low period violates the I2C spec of 1.3 uS min Description: When the I2C module is programmed to operate at the maximum clock speed of 400 kHz (as defined by the I2C spec), the SCL clock low period violates the I2C spec of 1.3 uS min. The user must reduce the clock speed to obtain the SCL low time to meet the 1.3us I2C minimum required. This behavior means the SoC is not compliant to the I2C spec at 400kHz. Workaround: To meet the clock low period requirement in fast speed mode, SCL must be configured to 384KHz or less. " Implement the workaround by matching on the affected SoC specific compatible strings and by limiting the maximum bus frequency in case the SoC is affected.

2022-04-15i2c: pasemi: Wait for write xfers to finishMartin Povišer1-0/+6
Wait for completion of write transfers before returning from the driver. At first sight it may seem advantageous to leave write transfers queued for the controller to carry out on its own time, but there's a couple of issues with it: * Driver doesn't check for FIFO space. * The queued writes can complete while the driver is in its I2C read transfer path which means it will get confused by the raising of XEN (the 'transaction ended' signal). This can cause a spurious ENODATA error due to premature reading of the MRXFIFO register. Adding the wait fixes some unreliability issues with the driver. There's some efficiency cost to it (especially with pasemi_smb_waitready doing its polling), but that will be alleviated once the driver receives interrupt support.

2022-04-15dm: fix bio length of empty flushShin'ichiro Kawasaki1-0/+1
The commit 92986f6b4c8a ("dm: use bio_clone_fast in alloc_io/alloc_tio") removed bio_clone_fast() call from alloc_tio() when ci->io->tio is available. In this case, ci->bio is not copied to ci->io->tio.clone. This is fine since init_clone_info() sets same values to ci->bio and ci->io->tio.clone. However, when incoming bios have REQ_PREFLUSH flag, __send_empty_flush() prepares a zero length bio on stack and set it to ci->bio. At this time, ci->io->tio.clone still keeps non-zero length. When alloc_tio() chooses this ci->io->tio.clone as the bio to map, it is passed to targets as non-empty flush bio. It causes bio length check failure in dm-zoned and unexpected operation such as dm_accept_partial_bio() call. To avoid the non-empty flush bio, set zero length to ci->io->tio.clone in __send_empty_flush().

2022-04-15serial: amba-pl011: do not time out prematurely when draining tx fifoLino Sanfilippo1-2/+7
The current timeout for draining the tx fifo in RS485 mode is calculated by multiplying the time it takes to transmit one character (with the given baud rate) with the maximal number of characters in the tx queue. This timeout is too short for two reasons: First when calculating the time to transmit one character integer division is used which may round down the result in case of a remainder of the division. Fix this by rounding up the division result. Second the hardware may need additional time (e.g for first putting the characters from the fifo into the shift register) before the characters are actually put onto the wire. To be on the safe side double the current maximum number of iterations that are used to wait for the queue draining.

2022-04-15tty: n_gsm: fix wrong signal octets encoding in MSCDaniel Starke1-13/+5
n_gsm is based on the 3GPP 07.010 and its newer version is the 3GPP 27.010. See https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=1516 The changes from 07.010 to 27.010 are non-functional. Therefore, I refer to the newer 27.010 here. The value of the modem status command (MSC) frame contains an address field, control signal and optional break signal octet. The address field is encoded as described in chapter 5.2.1.2 with only one octet (may be extended to more in future versions of the standard). Whereas the control signal and break signal octet are always one byte each. This is strange at first glance as it makes the EA bit redundant. However, the same two octets are also encoded as header in convergence layer type 2 as described in chapter 5.5.2. No header length field is given and the only way to test if there is an optional break signal octet is via the EA flag which extends the control signal octet with a break signal octet. Now it becomes obvious how the EA bit for those two octets shall be encoded in the MSC frame. The current implementation treats the signal octet different for MSC frame and convergence layer type 2 header even though the standard describes it for both in the same way. Use the EA bit to encode the signal octets not only in the convergence layer type 2 header but also in the MSC frame in the same way with either 1 or 2 bytes in case of an optional break signal. Adjust the receiving path accordingly in gsm_control_modem().
