kernfs: pass struct ns_common instead of const void * for namespace tags

2026-04-09T12:36:52Z

kernfs has historically used const void * to pass around namespace tags used for directory-level namespace filtering. The only current user of this is sysfs network namespace tagging where struct net pointers are cast to void *. Replace all const void * namespace parameters with const struct ns_common * throughout the kernfs, sysfs, and kobject namespace layers. This includes the kobj_ns_type_operations callbacks, kobject_namespace(), and all sysfs/kernfs APIs that accept or return namespace tags. Passing struct ns_common is needed because various codepaths require access to the underlying namespace. A struct ns_common can always be converted back to the concrete namespace type (e.g., struct net) via container_of() or to_ns_common() in the reverse direction. This is a preparatory change for switching to ns_id-based directory iteration to prevent a KASLR pointer leak through the current use of raw namespace pointers as hash seeds and comparison keys.

mm: rename zap_vma_ptes() to zap_special_vma_range()

2026-04-05T20:53:15Z

zap_vma_ptes() is the only zapping function we export to modules. It's essentially a wrapper around zap_vma_range(), however, with some safety checks: * That the passed range fits fully into the VMA * That it's only used for VM_PFNMAP We will add support for VM_MIXEDMAP next, so use the more-generic term "special vma", although "special" is a bit overloaded. Maybe we'll later just support any VM_SPECIAL flag. While at it, improve the kerneldoc.

drivers: net: drop ipv6_stub usage and use direct function calls

2026-03-29T18:21:23Z

As IPv6 is built-in only, the ipv6_stub infrastructure is no longer necessary. Convert all drivers currently utilizing ipv6_stub to make direct function calls. The fallback functions introduced previously will prevent linkage errors when CONFIG_IPV6 is disabled. Signed-off-by: Fernando Fernandez Mancera Tested-by: Ricardo B. Marlière Reviewed-by: Jason A.
