treewide: Change list_sort to use const pointers

2021-04-08T23:04:22+00:00

list_sort() internally casts the comparison function passed to it to a different type with constant struct list_head pointers, and uses this pointer to call the functions, which trips indirect call Control-Flow Integrity (CFI) checking. Instead of removing the consts, this change defines the list_cmp_func_t type and changes the comparison function types of all list_sort() callers to use const pointers, thus avoiding type mismatches.

drm: Refuse to create zero width/height cmdline modes

2021-04-01T17:29:16+00:00

If the user specifies zero width/height cmdline mode i915 will blow up as the fbdev path will bypass the regular fb sanity check that would otherwise have refused to create a framebuffer with zero width/height. The reason I thought to try this is so that I can force a specific depth for fbdev without actually having to hardcode the mode on the kernel cmdline. Eg. if I pass video=0x0-8 I will get an 8bpp framebuffer at my monitor's native resolution.

drm/modes: Switch to 64bit maths to avoid integer overflow

2021-01-14T17:37:53+00:00

The new >8k CEA modes have dotclocks reaching 5.94 GHz, which means our clock*1000 will now overflow the 32bit unsigned integer. Switch to 64bit maths to avoid it.

drm: Replace HTTP links with HTTPS ones

2020-07-20T09:47:28+00:00

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.
