The provided 'size' is the total space to -+ * be added in longs (i.e. it's 8 * 'size' bytes), including the size of -+ * the added element.

This is done prior to kABI freeze -+ * for structs that cannot be expanded later using RH_KABI_EXTEND (for -+ * example because they are embedded in another struct or because they are -+ * allocated by drivers or because they use unusual memory layout). The -+ * size of the reserved field is 'unsigned long' and is assumed to be -+ * 8 bytes. -+ * -+ * The argument is a number unique for the given struct; usually, multiple -+ * RH_KABI_RESERVE macros are added to a struct with numbers starting from -+ * one. -+ * -+ * Example usage: -+ * struct foo { -+ * int a; -+ * RH_KABI_RESERVE(1) -+ * RH_KABI_RESERVE(2) -+ * RH_KABI_RESERVE(3) -+ * RH_KABI_RESERVE(4) -+ * }; -+ * -+ * RH_KABI_USE -+ * Uses a previously reserved field or multiple fields. The arguments are -+ * one or more numbers assigned to RH_KABI_RESERVE, followed by a field to -+ * be put in their place.

See also RH_KABI_RESERVED, these two -+ * approaches can (and often are) combined. -+ * -+ * To use this for 'struct foo' (the "base structure"), define a new -+ * structure called 'struct foo_rh'; this new struct is called "auxiliary -+ * structure". Then add RH_KABI_AUX_EMBED or RH_KABI_AUX_PTR to the end -+ * of the base structure. The argument is the name of the base structure, -+ * without the 'struct' keyword. -+ * -+ * RH_KABI_AUX_PTR stores a pointer to the aux structure in the base -+ * struct. The lifecycle of the aux struct needs to be properly taken -+ * care of. -+ * -+ * RH_KABI_AUX_EMBED embeds the aux struct into the base struct. This -+ * cannot be used when the base struct is itself embedded into another -+ * struct, allocated in an array, etc. -+ * -+ * Both approaches (ptr and embed) work correctly even when the aux struct -+ * is allocated by modules. To ensure this, the code responsible for -+ * allocation/assignment of the aux struct has to properly set the size of -+ * the aux struct; see the RH_KABI_AUX_SET_SIZE and RH_KABI_AUX_INIT_SIZE -+ * macros. -+ * -+ * New fields can be later added to the auxiliary structure, always to its -+ * end. Note the auxiliary structure cannot be shrunk in size later (i.e., -+ * fields cannot be removed, only deprecated). Any code accessing fields -+ * from the aux struct must guard the access using the RH_KABI_AUX macro. -+ * The access itself is then done via a '_rh' field in the base struct. -+ * -+ * The auxiliary structure is not guaranteed for access by modules unless -+ * explicitly commented as such in the declaration of the aux struct -+ * itself or some of its elements. -+ * -+ * Example: -+ * -+ * struct foo_rh { -+ * int newly_added; -+ * }; -+ * -+ * struct foo { -+ * bool big_hammer; -+ * RH_KABI_AUX_PTR(foo) -+ * }; -+ * -+ * void use(struct foo *f) -+ * { -+ * if (RH_KABI_AUX(f, foo, newly_added)) -+ * f->_rh->newly_added = 123; -+ * else -+ * // the field 'newly_added' is not present in the passed -+ * // struct, fall back to old behavior -+ * f->big_hammer = true; -+ * } -+ * -+ * static struct foo_rh my_foo_rh { -+ * .newly_added = 0; -+ * } -+ * -+ * static struct foo my_foo = { -+ * .big_hammer = false, -+ * ._rh = &my_foo_rh, -+ * RH_KABI_AUX_INIT_SIZE(foo) -+ * }; -+ * -+ * RH_KABI_USE_AUX_PTR -+ * Creates an auxiliary structure post kABI freeze. This works by using -+ * two reserved fields (thus there has to be two reserved fields still -+ * available) and converting them to RH_KABI_AUX_PTR. -+ * -+ * Example: -+ * -+ * struct foo_rh { -+ * }; -+ * -+ * struct foo { -+ * int a; -+ * RH_KABI_RESERVE(1) -+ * RH_KABI_USE_AUX_PTR(2, 3, foo) -+ * }; -+ * -+ * RH_KABI_AUX_SET_SIZE -+ * RH_KABI_AUX_INIT_SIZE -+ * Calculates and stores the size of the auxiliary structure. -+ * -+ * RH_KABI_AUX_SET_SIZE is for dynamically allocated base structs, -+ * RH_KABI_AUX_INIT_SIZE is for statically allocated case structs. -+ * -+ * These macros must be called from the allocation (RH_KABI_AUX_SET_SIZE) -+ * or declaration (RH_KABI_AUX_INIT_SIZE) site, regardless of whether -+ * that happens in the kernel or in a module. Without calling one of -+ * these macros, the aux struct will appear to have no fields to the -+ * kernel. -+ * -+ * Note: since RH_KABI_AUX_SET_SIZE is intended to be invoked outside of -+ * a struct definition, it does not add the semicolon and must be -+ * terminated by semicolon by the caller. -+ * -+ * RH_KABI_AUX -+ * Verifies that the given field exists in the given auxiliary structure. -+ * This MUST be called prior to accessing that field; failing to do that -+ * may lead to invalid memory access. -+ * -+ * The first argument is a pointer to the base struct, the second argument -+ * is the name of the base struct (without the 'struct' keyword), the -+ * third argument is the field name. -+ * -+ * This macro works for structs extended by either of RH_KABI_AUX_EMBED, -+ * RH_KABI_AUX_PTR and RH_KABI_USE_AUX_PTR. -+ * -+ * RH_KABI_FORCE_CHANGE -+ * Force change of the symbol checksum. The argument of the macro is a -+ * version for cases we need to do this more than once. -+ * -+ * This macro does the opposite: it changes the symbol checksum without -+ * actually changing anything about the exported symbol. It is useful for -+ * symbols that are not whitelisted, we're changing them in an -+ * incompatible way and want to prevent 3rd party modules to silently -+ * corrupt memory. Instead, by changing the symbol checksum, such modules -+ * won't be loaded by the kernel. This macro should only be used as a -+ * last resort when all other KABI workarounds have failed. -+ * -+ * RH_KABI_EXCLUDE -+ * !!! WARNING: DANGEROUS, DO NOT USE unless you are aware of all the !!! -+ * !!! implications. This should be used ONLY EXCEPTIONALLY and only !!! -+ * !!! under specific circumstances. Very likely, this macro does not !!! -+ * !!! do what you expect it to do. Note that any usage of this macro !!! -+ * !!! MUST be paired with a RH_KABI_FORCE_CHANGE annotation of !!! -+ * !!! a suitable symbol (or an equivalent safeguard) and the commit !!! -+ * !!! log MUST explain why the chosen solution is appropriate. !!! -+ * -+ * Exclude the element from checksum generation. Any such element is -+ * considered not to be part of the kABI whitelist and may be changed at -+ * will. Note however that it's the responsibility of the developer -+ * changing the element to ensure 3rd party drivers using this element -+ * won't panic, for example by not allowing them to be loaded. That can -+ * be achieved by changing another, non-whitelisted symbol they use, -+ * either by nature of the change or by using RH_KABI_FORCE_CHANGE. -+ * -+ * Also note that any change to the element must preserve its size. Change -+ * of the size is not allowed and would constitute a silent kABI breakage. -+ * Beware that the RH_KABI_EXCLUDE macro does not do any size checks. -+ * -+ * RH_KABI_BROKEN_INSERT -+ * RH_KABI_BROKEN_REMOVE -+ * Insert a field to the middle of a struct / delete a field from a struct. -+ * Note that this breaks kABI! It can be done only when it's certain that -+ * no 3rd party driver can validly reach into the struct. A typical -+ * example is a struct that is: both (a) referenced only through a long -+ * chain of pointers from another struct that is part of a whitelisted -+ * symbol and (b) kernel internal only, it should have never been visible -+ * to genksyms in the first place. -+ * -+ * Another example are structs that are explicitly exempt from kABI -+ * guarantee but we did not have enough foresight to use RH_KABI_EXCLUDE. -+ * In this case, the warning for RH_KABI_EXCLUDE applies. -+ * -+ * A detailed explanation of correctness of every RH_KABI_BROKEN_* macro -+ * use is especially important. -+ * -+ * RH_KABI_BROKEN_INSERT_BLOCK -+ * RH_KABI_BROKEN_REMOVE_BLOCK -+ * A version of RH_KABI_BROKEN_INSERT / REMOVE that allows multiple fields -+ * to be inserted or removed together.
