2023-01-12drm: document better that drivers shouldn't use drm_minor directlyDaniel Vetter
The documentation for struct drm_minor already states this, but that's not always that easy to find. Also due to historical reasons we still have the minor-centric interfaces (like drm_debugfs_create_files), but since this is now getting fixed we can put a few more pointers in place as to how this should be done ideally. Note that debugfs isn't there yet for all cases (debugfs files on kms objects like crtc/connector aren't supported, neither debugfs files with full fops), so the debugfs side of this is still rather aspirational and more for new users than converting everything existing. todo.rst covers the additional work needed already. Motivated by some discussion with Rodrigo on irc about how drm/xe should lay out its sysfs interfaces. v2: Make the debugfs situation clearer in the commit message, but don't elaborate more in the actual kerneldoc to avoid distracting from the main message around sysfs (Jani) Also fix some typos.

2023-01-07drm/mipi-dsi: Add a mipi_dsi_dcs_write_seq() macroJavier Martinez Canillas
Many panel drivers define dsi_dcs_write_seq() and dsi_generic_write_seq() macros to send DCS commands and generic write packets respectively, with the payload specified as a list of parameters instead of using arrays. There's already a macro for the former, introduced by commit 2a9e9daf75231 ("drm/mipi-dsi: Introduce mipi_dsi_dcs_write_seq macro") so drivers can be changed to use that. But there isn't one yet for the latter, let's add it.

2023-01-03drm/format-helper: Simplify drm_fb_build_fourcc_list()Thomas Zimmermann
The DRM helper drm_fb_build_fourcc_list() creates a list of color formats for primary planes of the generic drivers. Simplify the helper: - It used to mix and filter native and emulated formats as provided by the driver. Now the only emulated format is XRGB8888, which is required as fallback by legacy software. Drop support for emulating any other formats. - Also convert alpha formats to their non-alpha counterparts. Generic drivers don't support primary planes with alpha formats and some DTs incorrectly advertise alpha channels for non-alpha hardware. So only export non-alpha formats for primary planes. With the simplified helper, scrap format lists of the affected generic drivers. All they need is the firmware buffer's native format, from which the helper creates the list of color formats.

2022-12-30arch: fix broken BuildID for arm64 and riscvMasahiro Yamada
Dennis Gilmore reports that the BuildID is missing in the arm64 vmlinux since commit 994b7ac1697b ("arm64: remove special treatment for the link order of head.o"). The issue is that the type of .notes section, which contains the BuildID, changed from NOTES to PROGBITS. Ard Biesheuvel figured out that whichever object gets linked first gets to decide the type of a section. The PROGBITS type is the result of the compiler emitting .note.GNU-stack as PROGBITS rather than NOTE. While Ard provided a fix for arm64, I want to fix this globally because the same issue is happening on riscv since commit 2348e6bf4421 ("riscv: remove special treatment for the link order of head.o"). This problem will happen in general for other architectures if they start to drop unneeded entries from scripts/head-object-list.txt. Discard .note.GNU-stack in include/asm-generic/vmlinux.lds.h.

Commands like Write Zeros can change the contents of a namespaces without actually transferring data. To protect against this, check the Commands Supported and Effects log is supported by the controller for any unprivileg command passthrough and refuse unprivileged passthrough if the command has any effects that can change data or metadata. Note: While the Commands Support and Effects log page has only been mandatory since NVMe 2.0, it is widely supported because Windows requires it for any command passthrough from userspace.

This isn't a Xen ABI because Xen doesn't let the guest turn these off except with the full SHUTDOWN_soft_reset mechanism.

Introduce the ability to track requests for the addition of DRM debugfs files at any time and have them added all at once during drm_dev_register(). Drivers can add DRM debugfs files to a device-managed list and, during drm_dev_register(), all added files will be created at once. Now, the drivers can use the functions drm_debugfs_add_file() and drm_debugfs_add_files() to create DRM debugfs files instead of using the drm_debugfs_create_files() function.

2022-12-19net: Introduce sk_use_task_frag in struct sock.Guillaume Nault
Sockets that can be used while recursing into memory reclaim, like those used by network block devices and file systems, mustn't use current->task_frag: if the current process is already using it, then the inner memory reclaim call would corrupt the task_frag structure. To avoid this, sk_page_frag() uses ->sk_allocation to detect sockets that mustn't use current->task_frag, assuming that those used during memory reclaim had their allocation constraints reflected in ->sk_allocation. This unfortunately doesn't cover all cases: in an attempt to remove all usage of GFP_NOFS and GFP_NOIO, sunrpc stopped setting these flags in ->sk_allocation, and used memalloc_nofs critical sections instead. This breaks the sk_page_frag() heuristic since the allocation constraints are now stored in current->flags, which sk_page_frag() can't read without risking triggering a cache miss and slowing down TCP's fast path. This patch creates a new field in struct sock, named sk_use_task_frag, which sockets with memory reclaim constraints can set to false if they can't safely use current->task_frag. In such cases, sk_page_frag() now always returns the socket's page_frag (->sk_frag). The first user is sunrpc, which needs to avoid using current->task_frag but can keep ->sk_allocation set to GFP_KERNEL otherwise. Eventually, it might be possible to simplify sk_page_frag() by only testing ->sk_use_task_frag and avoid relying on the ->sk_allocation heuristic entirely (assuming other sockets will set ->sk_use_task_frag according to their constraints in the future). The new ->sk_use_task_frag field is placed in a hole in struct sock and belongs to a cache line shared with ->sk_shutdown. Therefore it should be hot and shouldn't have negative performance impacts on TCP's fast path (sk_shutdown is tested just before the while() loop in tcp_sendmsg_locked()).
