2016-03-05Fix SELinux signatures in runtimeLaszlo Szekeres
The SELinux function signatures have changed between version 2.2 and 2.3. In particular, the type of the "security context" parameter was changed from char * to const char *, with the following patch: SELinuxProject/selinux@9eb9c9327563014ad6a807814e7975424642d5b9. Recent Linux distributions (e.g. Ubuntu 15.10) ship with the updated version of libselinux. This change makes the SELinux runtime compatible with the newer versions of the library by replacing security_context_t with its original char * definition and defining it as const only if the installed library does so. Whether the system uses const char * types is detected with the configure script. Fixes klee/klee#303.
2015-06-03Added an option --readable-posix-inputs which is used to turn on/off the CEX ↵Cristian Cadar
preferences added in the POSIX model. Removed option --prefer-cex which controlled all CEX preferences.
2015-04-25Change install location of KLEE's bytecode runtime librariesDan Liew
to ``${PREFIX}/lib/klee/runtime``. This addresses issue #233
2015-04-25Clean up the installation/building of the runtime libraries.Dan Liew
* We don't need to build the native versions so that is now disabled * We don't need to install (and hence build) the bytecode archive library versions of klee-libc or kleeRuntimeIntrinsic for new versions of LLVM right now (this is kind of messy).

2014-09-14Replace fprintf with klee_warnings for POSIX libMartin Nowack
2014-01-09Fixed race condition in parallel build where a symbolic linkDan Liew
(for klee-uclibc) would be created before the destination directory existed.
2013-12-21klee-uclibc detection is now a lot cleaner. KLEE now assumesDan Liew
it can find klee-uclibc inside the same folder as the other runtime libraries with the name "klee-uclibc.bca" This is implemented as follows: * When building, a sym-link is created to klee-uclibc's libc.a file in the same directory that the rest of KLEE's runtime libraries are built. This done so that if a developer changes klee-uclibc on their system then the correct version of klee-uclibc is used by KLEE. * When installing, klee-uclibc's libc.a file is installed in the same directory that the rest of KLEE's runtime libraries are installed. In addition the configure script argument --with-uclibc can now operate in two ways. It can either be passed the path to the root of klee-uclibc or it can be passed a path to the libc.a file built by klee-uclibc. This new behaviour has been added to allow users to potential use pre-built versions of klee-uclibc.

2013-11-15Removed testing-env file. As for testing-dir that was removed in aCristian Cadar
prior patch, this is part of the CU experiments and doesn't really belong here.

2013-09-25Merge pull request #25 from paulmar/masterCristian Cadar
Added some of the common *at functions & others to the model. Obey --max-forks in switch statements.

Fix implementation for putchar
2013-09-18Compile separate version of fd files only for LLVM 3.3 or higherMartin Nowack
2013-09-02Implemented runtime check for overshift (controllable with --check-overshiftDan Liew
command line argument). Overshift is where a Shl, AShr or LShr has a shift width greater than the bit width of the first operand. This is undefined behaviour in LLVM so we report this as an error.
2013-09-02Fixed multiple definitions of POSIX file functionsMartin Nowack
Function like stat() were defined for 32bit and 64bit version. Added compile time based selection of appropriate version using GNUC macros __x86_64__ and __ppc64__.

2013-08-27Fix implementation for putcharMartin Nowack
According to manual: putchar() return the character written as an unsigned char cast to an int or EOF on error. Use return value of write to return the correct value for putchar.
2013-08-27Port to LLVM 3.3Martin Nowack
Major changes are: - Switching to llvm-link to build archive files - Use GetMallocUsage instead of GetTotalMemoryUsage (be aware of bug in LLVM 3.3 http://llvm.org/bugs/show_bug.cgi?id=16847) - intrinsic library functions like memcpy/mov/set use weak linkage to be replaced by e.g. uclibc functions - rewrote linking with library - enhanced MemoryLimit test case to check if mallocs were successful

2012-10-24Patch by Dan Liew: " Added "sys/resource.h" include to POSIX stubCristian Cadar
methods. This fixes build problems (at least on my machine glibc 2.16.0-2) The __priority_which_t and __rlimit_resource_t data types which functions set_priority(), setrlimit() and setrlimit64() need are not defined in any of the headers the runtime/POSIX/stubs.c includes. It appears in the past the "sys/resource.h" was included by "sys/wait.h" but in the recent version of glibc I am using it is not. So to fix this I've added the include." git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@166554 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-11This is a workaround for the infinite loop reported at Cristian Cadar
http://keeda.stanford.edu/pipermail/klee-dev/2011-August/000723.html KLEE needs to use --fno-builtin when compiling its version of memset. However, this patch also adds the workaround suggested by Paul in the thread above, since support for --fno-builtin was added to llvm-gcc only after LLVM 2.9 was released. More details about this issue can be found here: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20110411/119376.html http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20110711/124131.html Thanks to Paul and arrowdodger for their explanations and patches. git-svn-id: https://llvm.org/svn/llvm-project/klee/trunk@146350 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-28Applied Stefan Bucur's patch fromCristian Cadar
http://llvm.org/bugs/show_bug.cgi?id=6690.
