lib: vsprintf: use _parse_integer() instead of _parse_integer_limit()

2026-06-29T18:05:39+00:00

Use _parse_integer() that allows optional arguments to be explicitly initialised. Signed-off-by: Andy Shevchenko Acked-by: Petr Mladek Signed-off-by: Rodrigo Alencar Signed-off-by: Jonathan Cameron

lib/vsprintf: Make no_hash_pointers take effect early

2026-06-25T09:19:34+00:00

The no_hash_pointers boot parameter is now handled as an alias for hash_pointers=never. However, hash_pointers=never only records the selected mode during early parameter parsing, and no_hash_pointers is not updated until hash_pointers_finalize() runs later from SLUB init. This leaves a window during very early boot where %p output is still hashed even though the user explicitly requested unhashed pointers with no_hash_pointers or hash_pointers=never. Set no_hash_pointers as soon as the "never" mode is parsed. The later hash_pointers_finalize() call still keeps the final policy decision in one place, but explicit requests to disable pointer hashing now take effect for early boot users too.

vsprintf: Add upper case flavour to %p[mM]

2026-06-12T12:20:25+00:00

Some of the (ABI aware) code needs an upper case when printing MAC addresses. Introduce an extension for that into the existing %p[mM].

lib/vsprintf: Require exact hash_pointers mode matches

2026-05-26T09:06:12+00:00

hash_pointers= accepts a small set of mode strings, but the parser uses strncmp() with the length of each valid mode. That accepts values with trailing garbage, such as hash_pointers=autobots or hash_pointers=nevermind, as valid aliases for auto and never. Use strcmp() so that only the documented mode strings are accepted. Invalid values will continue to fall back to auto through the existing unknown-mode path.
