* Fix abort in jemalloc extent coalescing.Marcin Wojtas2020-12-181-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix error in extent_try_coalesce_impl(), which could cause abort to happen when trying to coalesce extents backwards. The error could happen because of how extent_before_get() function works. This function gets address of previous extent, by subtracting page size from current extent address. If current extent is located at PAGE_SIZE offset, this address resolved to 0x0000. An assertion in rtree_leaf_elm_lookup then caused the running program to abort. This problem was discovered when trying to build world on 32-bit machines with ASLR and PIE enabled. The problem was encountered on armv7 and i386 machines, but most likely other 32-bit architectures are affected as well. While this patch fixes one problem with buildworld on 32-bit platforms with ASLR, the build still fails, however it happens much later and due to lack of memory. The change is aligned with accepted fix in the upstream Jemalloc repository (https://github.com/jemalloc/jemalloc/pull/1973). As it doesn't apply on top of Jemalloc tree, its updated version was eventually merged: https://github.com/jemalloc/jemalloc/pull/2003 PR: 249937 Submitted by: Dawid Gorecki <dgr@semihalf.com> Obtained from: Semihalf Sponsored by: Stormshield Differential Revision: https://reviews.freebsd.org/D27025 Notes: svn path=/head/; revision=368756

The patch fixes this by explicitly casting the 'len' variable as unsigned char' inside the 'switch' statement so that value of expression " '?' | 0x80 " falls within the legal values of the variable 'len'.

Instead, functions calls are indirected through the interposing table, similar to how pthread stubs in libc are already done. Libc by default points either to syscall trampolines or to existing libc implementations. On libthr load, libthr rewrites the pointers to the cancellable implementations already in libthr. The interposition table is separate from pthreads stubs indirection table to not pull pthreads stubs into static binaries. - Postpone the malloc(3) internal mutexes initialization until libthr is loaded. This avoids recursion between calloc(3) and static pthread_mutex_t initialization. - Reinstall signal handlers with wrapper on libthr load. The _rtld_is_dlopened(3) is used to avoid useless calls to sigaction(2) when libthr is statically referenced from the main binary. In the process, fix openat(2), swapcontext(2) and setcontext(2) interposing. The libc symbols were exported at different versions than libthr interposers. Export both libc and libthr versions from libc now, with default set to the higher version from libthr. Remove unused and disconnected swapcontext(3) userspace implementation from libc/gen.
