2023-12-11drm/i915: Fix ADL+ tiled plane stride when the POT stride is smaller than ↵Ville Syrjälä
the original plane_view_scanout_stride() currently assumes that we had to pad the mapping stride with dummy pages in order to align it. But that is not the case if the original fb stride exceeds the aligned stride used to populate the remapped view, which is calculated from the user specified framebuffer width rather than the user specified framebuffer stride. Ignore the original fb stride in this case and just stick to the POT aligned stride. Getting this wrong will cause the plane to fetch the wrong data, and can lead to fault errors if the page tables at the bogus location aren't even populated. TODO: figure out if this is OK for CCS, or if we should instead increase the width of the view to cover the entire user specified fb stride instead...

2023-12-11drm/i915: Fix intel_atomic_setup_scalers() plane_state handlingVille Syrjälä
Since the plane_state variable is declared outside the scaler_users loop in intel_atomic_setup_scalers(), and it's never reset back to NULL inside the loop we may end up calling intel_atomic_setup_scaler() with a non-NULL plane state for the pipe scaling case. That is bad because intel_atomic_setup_scaler() determines whether we are doing plane scaling or pipe scaling based on plane_state!=NULL. The end result is that we may miscalculate the scaler mode for pipe scaling. The hardware becomes somewhat upset if we end up in this situation when scanning out a planar format on a SDR plane. We end up programming the pipe scaler into planar mode as well, and the result is a screenfull of garbage. Fix the situation by making sure we pass the correct plane_state==NULL when calculating the scaler mode for pipe scaling.

2023-12-11drm/i915: Fix remapped stride with CCS on ADL+Ville Syrjälä
On ADL+ the hardware automagically calculates the CCS AUX surface stride from the main surface stride, so when remapping we can't really play a lot of tricks with the main surface stride, or else the AUX surface stride would get miscalculated and no longer match the actual data layout in memory. Supposedly we could remap in 256 main surface tile units (AUX page(4096)/cachline(64)*4(4x1 main surface tiles per AUX cacheline)=256 main surface tiles), but the extra complexity is probably not worth the hassle. So let's just make sure our mapping stride is calculated from the full framebuffer stride (instead of the framebuffer width). This way the stride we program into PLANE_STRIDE will be the original framebuffer stride, and thus there will be no change to the AUX stride/layout.

2023-12-11drm/i915: Use internal class when counting engine resetsTvrtko Ursulin
Commit 503579448db9 ("drm/i915/gsc: Mark internal GSC engine with reserved uabi class") made the GSC0 engine not have a valid uabi class and so broke the engine reset counting, which in turn was made class based in cb823ed9915b ("drm/i915/gt: Use intel_gt as the primary object for handling resets"). Despite the title and commit text of the latter is not mentioning it (and has left the storage array incorrectly sized), tracking by class, despite it adding aliasing in hypthotetical multi-tile systems, is handy for virtual engines which for instance do not have a valid engine->id. Therefore we keep that but just change it to use the internal class which is always valid. We also add a helper to increment the count, which aligns with the existing getter. What was broken without this fix were out of bounds reads every time a reset would happen on the GSC0 engine, or during selftests when storing and cross-checking the counts in igt_live_test_begin and igt_live_test_end.

The rvu_dl will be freed in rvu_nix_health_reporters_destroy(rvu_dl) after the create_workqueue fails, and after that free, the rvu_dl will be translate back through the following call chain: rvu_nix_health_reporters_destroy |-> rvu_nix_health_reporters_create |-> rvu_health_reporters_create |-> rvu_register_dl (label err_dl_health) Finally. in the err_dl_health label, rvu_dl being freed again in rvu_health_reporters_destroy(rvu) by rvu_nix_health_reporters_destroy. In the second calls of rvu_nix_health_reporters_destroy, however, it uses rvu_dl->rvu_nix_health_reporter, which is already freed at the end of rvu_nix_health_reporters_destroy in the first call. So this patch prevents the first destroy by instantly returning -ENONMEN when create_workqueue fails. In addition, since the failure of create_workqueue is the only entrence of label err, it has been integrated into the error-handling path of create_workqueue.

2023-12-08qca_spi: Fix reset behaviorStefan Wahren
In case of a reset triggered by the QCA7000 itself, the behavior of the qca_spi driver was not quite correct: - in case of a pending RX frame decoding the drop counter must be incremented and decoding state machine reseted - also the reset counter must always be incremented regardless of sync state Fixes: 291ab06ecf67 ("net: qualcomm: new Ethernet over SPI driver for QCA7000") Signed-off-by: Stefan Wahren <wahrenst@gmx.net> Link: https://lore.kernel.org/r/20231206141222.52029-4-wahrenst@gmx.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-12-08qca_debug: Fix ethtool -G iface tx behaviorStefan Wahren
After calling ethtool -g it was not possible to adjust the TX ring size again: # ethtool -g eth1 Ring parameters for eth1: Pre-set maximums: RX: 4 RX Mini: n/a RX Jumbo: n/a TX: 10 Current hardware settings: RX: 4 RX Mini: n/a RX Jumbo: n/a TX: 10 # ethtool -G eth1 tx 8 netlink error: Invalid argument The reason for this is that the readonly setting rx_pending get initialized and after that the range check in qcaspi_set_ringparam() fails regardless of the provided parameter. So fix this by accepting the exposed RX defaults. Instead of adding another magic number better use a new define here.

2023-12-08qca_debug: Prevent crash on TX ring changesStefan Wahren
The qca_spi driver stop and restart the SPI kernel thread (via ndo_stop & ndo_open) in case of TX ring changes. This is a big issue because it allows userspace to prevent restart of the SPI kernel thread (via signals). A subsequent change of TX ring wrongly assume a valid spi_thread pointer which result in a crash. So prevent this by stopping the network traffic handling and temporary park the SPI thread.

2023-12-08team: Fix use-after-free when an option instance allocation failsFlorent Revest
In __team_options_register, team_options are allocated and appended to the team's option_list. If one option instance allocation fails, the "inst_rollback" cleanup path frees the previously allocated options but doesn't remove them from the team's option_list. This leaves dangling pointers that can be dereferenced later by other parts of the team driver that iterate over options. This patch fixes the cleanup path to remove the dangling pointers from the list. As far as I can tell, this uaf doesn't have much security implications since it would be fairly hard to exploit (an attacker would need to make the allocation of that specific small object fail) but it's still nice to fix.

2023-12-08PCI: loongson: Limit MRRS to 256Jiaxun Yang
This is a partial revert of 8b3517f88ff2 ("PCI: loongson: Prevent LS7A MRRS increases") for MIPS-based Loongson. Some MIPS Loongson systems don't support arbitrary Max_Read_Request_Size (MRRS) settings. 8b3517f88ff2 ("PCI: loongson: Prevent LS7A MRRS increases") worked around that by (1) assuming that firmware configured MRRS to the maximum supported value and (2) preventing the PCI core from increasing MRRS. Unfortunately, some firmware doesn't set that maximum MRRS correctly, which results in devices not being initialized correctly. One symptom, from the Debian report below, is this: ata4.00: exception Emask 0x0 SAct 0x20000000 SErr 0x0 action 0x6 frozen ata4.00: failed command: WRITE FPDMA QUEUED ata4.00: cmd 61/20:e8:00:f0:e1/00:00:00:00:00/40 tag 29 ncq dma 16384 out res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) ata4.00: status: { DRDY } ata4: hard resetting link Limit MRRS to 256 because MIPS Loongson with higher MRRS support is considered rare. This must be done at device enablement stage because the MRRS setting may get lost if PCI_COMMAND_MASTER on the parent bridge is cleared, and we are only sure parent bridge is enabled at this point.
