2023-01-20net: mdio: Remove support for building C45 muxed addressesAndrew Lunn
The old way of performing a C45 bus transfer created a special register value and passed it to the MDIO bus driver, in the hope it would see the MII_ADDR_C45 bit set, and perform a C45 transfer. Now that there is a clear separation of C22 and C45, this scheme is no longer used. Remove all the #defines and helpers, to prevent any code being added which tries to use it.

2023-01-20bpf: Invalidate slices on destruction of dynptrs on stackKumar Kartikeya Dwivedi
The previous commit implemented destroy_if_dynptr_stack_slot. It destroys the dynptr which given spi belongs to, but still doesn't invalidate the slices that belong to such a dynptr. While for the case of referenced dynptr, we don't allow their overwrite and return an error early, we still allow it and destroy the dynptr for unreferenced dynptr. To be able to enable precise and scoped invalidation of dynptr slices in this case, we must be able to associate the source dynptr of slices that have been obtained using bpf_dynptr_data. When doing destruction, only slices belonging to the dynptr being destructed should be invalidated, and nothing else. Currently, dynptr slices belonging to different dynptrs are indistinguishible. Hence, allocate a unique id to each dynptr (CONST_PTR_TO_DYNPTR and those on stack). This will be stored as part of reg->id. Whenever using bpf_dynptr_data, transfer this unique dynptr id to the returned PTR_TO_MEM_OR_NULL slice pointer, and store it in a new per-PTR_TO_MEM dynptr_id register state member. Finally, after establishing such a relationship between dynptrs and their slices, implement precise invalidation logic that only invalidates slices belong to the destroyed dynptr in destroy_if_dynptr_stack_slot.

Implement support for a new note type NT_ARM64_ZT providing access to ZT0 when implemented. Since ZT0 is a register with constant size this is much simpler than for other SME state. As ZT0 is only accessible when PSTATE.ZA is set writes to ZT0 cause PSTATE.ZA to be set, the main alternative would be to return -EBUSY in this case but this seemed more constructive. Practical users are also going to be working with ZA anyway and have some understanding of the state.

Add new rewrite table and all the required functions, offload hooks and bookkeeping for maintaining it. The rewrite table reuses the app struct, and the entire set of app selectors. As such, some bookeeping code can be shared between the rewrite- and the APP table. New functions for getting, setting and deleting entries has been added. Apart from operating on the rewrite list, these functions do not emit a DCB_APP_EVENT when the list os modified. The new dcb_getrewr does a lookup based on selector and priority and returns the protocol, so that mappings from priority to protocol, for a given selector and ifindex is obtained. Also, a new nested attribute has been added, that encapsulates one or more app structs. This attribute is used to distinguish the two tables.

Currently we traverse all symbols of all modules to find the specified function for the specified module. But in reality, we just need to find the given module and then traverse all the symbols in it. Let's add a new parameter 'const char *modname' to function module_kallsyms_on_each_symbol(), then we can compare the module names directly in this function and call hook 'fn' after matching. If 'modname' is NULL, the symbols of all modules are still traversed for compatibility with other usage cases. Phase1: mod1-->mod2..(subsequent modules do not need to be compared) | Phase2: -->f1-->f2-->f3 Assuming that there are m modules, each module has n symbols on average, then the time complexity is reduced from O(m * n) to O(m) + O(n).

Now that we converted everything to just rely on struct mnt_idmap move it all into a separate file. This ensure that no code can poke around in struct mnt_idmap without any dedicated helpers and makes it easier to extend it in the future. Filesystems will now not be able to conflate mount and filesystem idmappings as they are two distinct types and require distinct helpers that cannot be used interchangeably. We are now also able to extend struct mnt_idmap as we see fit.

Convert to struct mnt_idmap. Last cycle we merged the necessary infrastructure in 256c8aed2b42 ("fs: introduce dedicated idmap type for mounts"). This is just the conversion to struct mnt_idmap. Currently we still pass around the plain namespace that was attached to a mount. This is in general pretty convenient but it makes it easy to conflate namespaces that are relevant on the filesystem with namespaces that are relevent on the mount level. Especially for non-vfs developers without detailed knowledge in this area this can be a potential source for bugs. Once the conversion to struct mnt_idmap is done all helpers down to the really low-level helpers will take a struct mnt_idmap argument instead of two namespace arguments. This way it becomes impossible to conflate the two eliminating the possibility of any bugs. All of the vfs and all filesystems only operate on struct mnt_idmap.
