In an in-source build this is usually +# harmless because $srcdir is `.', but things will broke when you +# start a VPATH build or use an absolute $srcdir. +# +# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, +# iff we strip the leading $srcdir from $ac_aux_dir. That would be: +# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` +# and then we would define $MISSING as +# MISSING="\${SHELL} $am_aux_dir/missing" +# This will work as long as MISSING is not called from configure, because +# unfortunately $(top_srcdir) has no meaning in configure. +# However there are other variables, like CC, which are often used in +# configure, and could therefore not use this "fixed" $ac_aux_dir. +# +# Another solution, used here, is to always expand $ac_aux_dir to an +# absolute PATH.

The + compiler finds every virtual call, and inserts a verification call + before the virtual call. The verification call takes the actual + vtable pointer value in the object through which the virtual call + is being made, and compares the vtable pointer against a set of all + valid vtable pointers that the object could contain (this set is + based on the declared type of the object). If the pointer is in + the valid set, execution is allowed to continue; otherwise the + program is halted. + + There are several pieces needed in order to make this work: 1. For + every virtual class in the program (i.e. a class that contains + virtual methods), we need to build the set of all possible valid + vtables that an object of that class could point to. This includes + vtables for any class(es) that inherit from the class under + consideration. 2. For every such data set we build up, we need a + way to find and reference the data set. This is complicated by the + fact that the real vtable addresses are not known until runtime, + when the program is loaded into memory, but we need to reference the + sets at compile time when we are inserting verification calls into + the program. 3. We need to find every virtual call in the program, + and insert the verification call (with the appropriate arguments) + before the virtual call. 4. We need some runtime library pieces: + the code to build up the data sets at runtime; the code to actually + perform the verification using the data sets; and some code to set + protections on the data sets, so they themselves do not become + hacker targets. + + To find and reference the set of valid vtable pointers for any given + virtual class, we create a special global varible for each virtual + class. We refer to this as the "vtable map variable" for that + class. The vtable map variable has the type "void *", and is + initialized by the compiler to NULL. At runtime when the set of + valid vtable pointers for a virtual class, e.g. class Foo, is built, + the vtable map variable for class Foo is made to point to the set. + During compile time, when the compiler is inserting verification + calls into the program, it passes the vtable map variable for the + appropriate class to the verification call, so that at runtime the + verification call can find the appropriate data set. + + The actual set of valid vtable pointers for a polymorphic class, + e.g. class Foo, cannot be built until runtime, when the vtables get + loaded into memory and their addresses are known. But the knowledge + about which vtables belong in which class' hierarchy is only known + at compile time. Therefore at compile time we collect class + hierarchy and vtable information about every virtual class, and we + generate calls to build up the data sets at runtime. To build the + data sets, we call one of the functions we add to the runtime + library, __VLTRegisterPair. __VLTRegisterPair takes two arguments, + a vtable map variable and the address of a vtable. If the vtable + map variable is currently NULL, it creates a new data set (hash + table), makes the vtable map variable point to the new data set, and + inserts the vtable address into the data set. If the vtable map + variable is not NULL, it just inserts the vtable address into the + data set. In order to make sure that our data sets are built before + any verification calls happen, we create a special constructor + initialization function for each compilation unit, give it a very + high initialization priority, and insert all of our calls to + __VLTRegisterPair into our special constructor initialization + function. */ + +/* This file contains the main externally visible runtime library + functions for vtable verification: __VLTChangePermission, + __VLTRegisterPair, and __VLTVerifyVtablePointer. It also contains + debug versions __VLTRegisterPairDebug and + __VLTVerifyVtablePointerDebug, which have extra parameters in order + to make it easier to debug verification failures. + + The final piece of functionality implemented in this file is symbol + resolution for multiple instances of the same vtable map variable. + If the same virtual class is used in two different compilation + units, then each compilation unit will create a vtable map variable + for the class. We need all instances of the same vtable map + variable to point to the same (single) set of valid vtable + pointers for the class, so we wrote our own hashtable-based symbol + resolution for vtable map variables (with a tiny optimization in + the case where there is only one instance of the variable). + + There are two other important pieces to the runtime for vtable + verification besides the main pieces that go into libstdc++.so: two + special tiny shared libraries, libvtv_init.so and libvtv_stubs.so. + libvtv_init.so is built from vtv_init.cc. It is designed to help + minimize the calls made to mprotect (see the comments in + vtv_init.cc for more details). Anything compiled with + "-fvtable-verify=std" must be linked with libvtv_init.so (the gcc + driver has been modified to do this). vtv_stubs.so is built from + vtv_stubs.cc. It replaces the main runtime functions + (__VLTChangePermissino, __VLTRegisterPair and + __VLTVerifyVtablePointer) with stub functions that do nothing.

We + have only tested the case where Key is uintptr_t, though it + theoretically should work for some other cases. All odd keys are + reserved, and must not be inserted into any of the sets. This code + is intended primarily for sets of pointers, and the code is + optimized for small sets (including size 0 and 1), but regardless + of the set size, insert() and contains() have close to O(1) speed + in practice. + + TODO(gpike): fix this comment. + + Recommended multithreaded use of a set: + + For speed, we want to use a lock-free test for set membership. The + code handles simultaneous reads and inserts, as long as at most one + insertion is in progress at a time. After an insert, other threads + may not immediately "see" the inserted key if they perform a + lock-free read, so we recommend retrying, as explained below. + + Also, to make data corruption less likely, we recommend using a + "normal" RW page as well as one or pages that are typically RO + but that can be switched to RW and back as needed. The latter + pages should contain sets. The former should contain a lock, L, + and an int or similar, num_writers. Then, to insert, something + like this would be safe: + o Acquire L. + o Increment num_writers; if that made it 1, change pages to RW. + o Release L. + o while (there are insertions to do in some set, S) { + acquire L; + do some insertions in S; + release L; + } + o Acquire L. + o Decrement num_writers; if that made it 0, change pages to RO. + o Release L. + + And to check if the set contains some key, one could use + set.contains(key) || + ({ Acquire L; bool b = set.contains(key); Release L; b; }) + + In this scheme, the number of threads with reads in progress isn't + tracked, so old sets can never be deleted. In addition, on some + architectures the intentionally racy reads might cause contains() + to return true when it should have returned false. This should be + no problem on x86, and most other machines, where reading or + writing an aligned uintptr_t is atomic. E.g., on those machines, + if *p is 0 and one thread does *p = x while another reads *p, the + read will see either 0 or x. + + To make the above easier, the insert_only_hash_sets class provides + an interface to manipulate any number of hash sets. One shouldn't + create objects of that class, as it has no member data and its + methods are static. + + So the recommended model is to have a single lock, a single + num_writers variable, and some number of sets. If lock contention + becomes a problem then the sets can be divided into k groups, each + of which has a lock and a num_writers variable; or each set can be + represented as a set of values that equal 0 mod m, a set of values + that equal 1 mod m, ..., plus a set of values that equal m-1 mod m. + + However, we expect most or all uses of this code to call contains() + much more frequently than anything else, so lock contention is + likely to be low. */ + +#include <algorithm> + +#ifndef HASHTABLE_STATS +#define HASHTABLE_STATS 0 +#endif + +#ifndef HASHTABLE_STATS_ATOMIC +#define HASHTABLE_STATS_ATOMIC 0 +#endif + +#if HASHTABLE_STATS +#if HASHTABLE_STATS_ATOMIC +/* Stat counters, with atomics. */ +#include <bits/atomic_word.h> + +typedef _Atomic_word _AtomicStatCounter; + +void +inc_by (_AtomicStatCounter &stat, int amount) +{ + __atomic_add_fetch (&stat, amount, __ATOMIC_ACQ_REL); +} + +#else + +/* Stat counters, but without atomics. */ +typedef int _AtomicStatCounter; + +void +inc_by (_AtomicStatCounter& stat, int amount) +{ + stat += amount; +} + +#endif + + +/* Number of calls to contains(), insert(), etc. */ +extern _AtomicStatCounter stat_insert; +extern _AtomicStatCounter stat_contains; +extern _AtomicStatCounter stat_resize; +extern _AtomicStatCounter stat_create; + +/* Sum of set size over all calls to contains(). */ +extern _AtomicStatCounter stat_contains_sizes; + +/* contains() calls in a set whose capacity is more than 1. */ +extern _AtomicStatCounter stat_contains_in_non_trivial_set; + +/* Probes in a set whose capacity is more than 1.
