# All library objects contain FreeBSD revision strings by default; they may be
# excluded as a space-saving measure. To produce a library that does
# not contain these strings, add -DSTRIP_FBSDID (see <sys/cdefs.h>) to CFLAGS
Remove references to the LIBC_SCCS and SYSLIBC_SCCS C macros. This language dates back to when libthr was libc_r that included its own syscalls and replaced libc entirely. It hasn't been relevant for a long time.

Remove libc, librtld_db, libthr packages, and further increase the constraints on what needs to be installed in a specific to maintain consistency during upgrades. Create a new clibs package containing libraries that are needed as a bare minimum for consistency. With much help and input from: kib Sponsored by: The FreeBSD Foundation

Enable symbol versioning by default. Use WITHOUT_SYMVER to disable it. Warning, after symbol versioning is enabled, going back is not easy (use WITHOUT_SYMVER at your own risk). Change the default thread library to libthr. There most likely still needs to be a version bump for at least the thread libraries. If necessary, this will happen later.

Fix initial exec TLS mode for dynamically loaded shared objects. If dso uses initial exec TLS mode, rtld tries to allocate TLS in static space. If there is no space left, the dlopen(3) fails. If space if allocated, initial content from PT_TLS segment is distributed to all threads' pcbs, which was missed and caused un-initialized TLS segment for such dso after dlopen(3). The mode is auto-detected either due to the relocation used, or if the DF_STATIC_TLS dynamic flag is set. In the later case, the TLS segment is tried to allocate earlier, which increases chance of the dlopen(3) to succeed. LLD was recently fixed to properly emit the flag, ld.bdf did it always.

Untangle jemalloc and mutexes initialization. The need to use libc malloc(3) from some places in libthr always caused issues. For instance, per-thread key allocation was switched to use plain mmap(2) to get storage, because some third party mallocs used keys for implementation of calloc(3). Even more important, libthr calls calloc(3) during initialization of pthread mutexes, and jemalloc uses pthread mutexes. Jemalloc provides some way to both postpone the initialization, and to make initialization to use specialized allocator, but this is very fragile and often breaks. See the referenced PR for another example. Add the small malloc implementation used by rtld, to libthr. Use it in thr_spec.c and for mutexes initialization. This avoids the issues with mutual dependencies between malloc and libthr in principle. The drawback is that some more allocations are not interceptable for alternate malloc implementations. There should be not too much memory use from this allocator, and the alternative, direct use of mmap(2) is obviously worse.

Merge all the copies of _tcb_ctor and _tcb_dtor. The amd64, i386, and sparc64 versions were identical, with the one difference where the former two used inline asm instead of _tcb_get. I have compared the function before and after replacing the asm with _tcb_get and found the object files to be identical. The arm, mips, and powerpc versions were almost identical. The only difference was the powerpc version used an alignment of 1 where arm and mips used 16. As this is an increase in alignment is will be safe. Along with this arm, mips, and powerpc all passed, when initial was true, the value returned from _tcb_get as the first argument to _rtld_allocate_tls. This would then return this pointer back to the caller. We can remove these extra calls by checking if initial is set and setting the thread control block directly. As this is what the sparc64 code does we can use it directly. As after these observations all the architectures can now have identical code we can merge them into a common file.
