* libdw: Fix eu_search_tree TOCTOU bugsAaron Merey2025-06-021-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | eu_tfind is used to facilitate lazy loading throughout libdw. If a result is not found via eu_tfind, work is done to load the result and cache it in an eu_search_tree. Some calls to eu_tfind allow for TOCTOU bugs. Multiple threads might race to call eu_tfind on some result that hasn't yet been cached. Multiple threads may then attempt to load the result which might cause an unnecessary amount of memory to be allocated. Additionally this memory may not get released when the associated libdw data structure is freed. Fix this by adding additional locking to ensure that only one thread performs lazy loading. One approach used in this patch is to preserve calls to eu_tfind without additional locking, but when the result isn't found then a lock is then used to synchronize access to the lazy loading code. An extra eu_tfind call has been added at the start of these critical section to synchronize verification that lazy loading should proceed. Another approach used is to simply synchronize entire calls to functions where lazy loading via eu_tfind might occur (__libdw_find_fde and __libdw_intern_expression). In this case, new _nolock variants of the eu_t* functions are used to avoid unnecessary double locking. lib/ * eu-search.c: Add eu_tsearch_nolock, eu_tfind_nolock and eu_tdelete_nolock functions. * eu-search.h: Ditto. libdw/ * cfi.h (struct Dwarf_CFI_s): Declare new mutex. * dwarf_begin_elf.c (valid_p): Initialize all locks for fake CUs. * dwarf_cfi_addrframe.c (dwarf_cfi_addrframe): Place lock around __libdw_find_fde. * dwarf_end.c (cu_free): Deallocate all locks unconditionally, whether or not the CU is fake. * dwarf_frame_cfa.c (dwarf_frame_cfa): Place lock around __libdw_intern_expression. * dwarf_frame_register.c (dwarf_frame_register): Ditto. * dwarf_getcfi.c (dwarf_getcfi): Initialize cfi lock. * dwarf_getlocation.c (is_constant_offset): Synchronize access to lazy loading section.

* libelf, readelf: Use validate_str also to check dynamic symstr dataMark Wielaard2025-02-141-0/+27
| | | | | | | | | | | | | | | | | | When dynsym/str was read through eu-readelf --dynamic by readelf process_symtab the string data was not validated, possibly printing unallocated memory past the end of the symstr data.

* Replace usage of ar with stored library manifest filesMichael Pratt2025-01-211-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ar program is called to assemble a list of objects within each archive to assist in building combined libraries, however make already has this information when processing the subdirectory for that respective library. The list can be saved in a "manifest" file instead of being generated whenever it is needed for use with other subdirectories. Even though the difference in time is insignificant, a simple "echo" and "cat" is as much as 10 times faster than a call to "ar t" for printing the archive members. Since elfutils builds ar, this also removes the awkward circular dependency where an installation of ar is required to build the libraries for ar. Additionally, not every version of ar is equally portable, as native versions of ar on macOS and other BSD-like distributions may print out a special archive member like "__.SYMDEF" which is not a compiled object but rather just metadata from ranlib, leading to a build failure. Avoid these limitations by removing usage of ar and adding build and clean rules for the usage of archive manifest files. * .gitignore: exclude ".manifest" file extension. * backends/Makefile.am: add manifest file build and clean rules. * debuginfod/Makefile.am: Likewise. * lib/Makefile.am: Likewise. * libasm/Makefile.am: Likewise. * libcpu/Makefile.am: Likewise. * libdw/Makefile.am: Likewise, and set object lists to manifest contents. * libdwelf/Makefile.am: Likewise. * libdwfl/Makefile.am: Likewise. * libebl/Makefile.am: Likewise. * libelf/Makefile.am: Likewise, and set object lists to manifest contents. * src/Makefile.am: Likewise.

* Update minimum C compiler supported to C11 plus stdatomic.hMark Wielaard2025-01-114-481/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were using a somewhat odd mix of gnu99 with a fallback atomics.h so we could build with gcc 4.7. Lets requires a compiler that can do at least C11 and has a stdatomic.h. So we can build against any C standard >= C11 (including C17 and C23). That means GCC 4.9+. GCC 4.9 was released in 2014. The lowest compiler version we check in the buildbots is currently GCC 8.3.0 (Debian old old stable, released in 2018). Also update the minimum autoconf version to 2.69. We would really like 2.70+ so we don't need the gnulib gnu11.m4. But 2.69 still seems in use on various stable systems. autoconf 2.70 was released end of 2020, autoconf 2.69 in 2012. * configure.ac (AC_PACKAGE_URL): Removed workaround for autoconf < 2.64.

Include system.h in all tests/ files that required it. Signed-off-by: Érico Rolim <[email protected]> Signed-off-by: Mark Wielaard <[email protected]>

* Use fallthrough attribute.Joshua Watt2018-02-102-0/+11
| | | | | | | | | | | | | | | Use __attribute__ ((fallthrough)) to indicate switch case fall through instead of a comment. This ensures that the fallthrough warning is not triggered even if the file is pre-processed (hence stripping the comments) before it is compiled. The actual fallback implementation is hidden behind a FALLBACK macro in case the compiler doesn't support it. Finally, the -Wimplict-fallthrough warning was upgraded to only allow the attribute to satisfy it; a comment alone is no longer sufficient. Signed-off-by: Joshua Watt <[email protected]>
