* jemalloc: avoid clash with C23 unreachable() macroRobert Clausecker2025-11-281-0/+3

* jemalloc: Remove bogus merge conflict markersWarner Losh2025-09-026-984/+0
| | | | | | | | | The merge markers were added, it seems, in one of my rebases. The HEAD entry is the merged code, as far as I can tell, and is what should be in the base. None of these files are used during the build. Noticed by: jhb Sponsored by: Netflix
* jemalloc: Merge from jemalloc 5.3.0 vendor branchWarner Losh2025-08-15122-3810/+11639
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This brings in a merge from jemalloc 5.3.0. It's almost fully scripted, except: Three conflicts resolved by hand: include/jemalloc/internal/test_hooks.h Use the new name src/extent.c Use the new code src/jemalloc.c Use the new code since je_realloc has moved The script is recorded in FREEBSD-upgrade. The old script did svn commands that were basically a rebase of our changes. This update has a series of diff reduction changes before this. Note: I'd planned on fixing the above three conflicts with commits, but ran out of time when I did this work in January. I got discouraged when jemalloc was EOL'd and didn't pick this back up. I did the above by hand to get this into FreeBSD 15.0 This work is a repeat of the work by Minsoo Choo who did all these changes and created a pull request. Given the importance of jemalloc, I audited these changes by redoing them in this series of commits (and with the script that was checked in). I did this to confince myself and anybody else in doubt that there was no supply chain attack. The diffs between this series of commits and Minsoo's work are minor (though the version skew makes adds some noise). Interested parties can independent audit each step, I hope. I've listed Minsoo as a co-author since without his pull request to test again, this wouldn't have been possible. Thanks to brooks@ for help with getting the jemalloc 3 ABI compat symbols right.

* jemalloc: Add JEMALLOC_PRIVATE_NAMESPACE for the libc namespaceWarner Losh2025-08-152-0/+4
| | | | | | | | | | | Gate the namespace dance on this define. This allows us to bootstrap new versions of jemalloc more easily. One of the steps of import is building to find what symbols need to be private. When we do that, we don't want to do this dance. No functional change. Sponsored by: Netflix

| | | | | | | | | | | | Add back more of the release for jemalloc for easier imports that can be audited for stray changes simply. However, trim out tests and msvc project files since they are easy and account for over half the size of the distro. No functional change. Sponsored by: Netflix
* Revert "jemalloc: Reduce diffs to 5.2.1 revert to using JEMALLOC_FALLTHROUGH"Warner Losh2024-12-151-1/+1
| | | | | | | | | This reverts commit 7bcf5319c1106b761bcb2a4facfeccf1b9db758d. Turns out this is needed for gcc, at least through gcc 14. This wasn't documented it the import when it came in, so revert with this note. Sponsored by: Netflix
* jemalloc: Reduce diffs to 5.2.1 revert to using JEMALLOC_FALLTHROUGHWarner Losh2024-12-131-1/+1
| | | | | | | | | In the import of 5.2.1 (c5ad81420c495), JEMALLOC_FALLTHROUGH was changed to break (judging by the tagged upstream sources). This changes it back to upstream. No functional change: this is just a textual change (though the fallthrough macro doesn't expand to break). Sponsored by: Netflix
* jemalloc: Move generated files into lib/libc treeWarner Losh2024-12-138-1737/+0
| | | | | | | | | | | | | | | Make it easire to update jemalloc by moving the FreeBSD specific files and the generated files into lib/libc. This allows us to regenerate them more easily, and emphasizes a bit that we may have to regenerate stuff from upstream. This is necessary to also unthin the import from the vendor branch as well (which will be needed to simplify the imports in the future since we are trying to use contrib/jemalloc for two different things). No functional change. Sponsored by: Netflix

* jemalloc: don't expose 3.0 compat symbolsBrooks Davis2024-08-221-11/+15
| | | | | | | | | | | | Don't provide default linkage for jemalloc 3.0 compatability symbols. We stopped declaring these interfaces with the introduction of jemalloc 4.0 prior to FreeBSD 11.0. Any code using them would have had to declare them manually so stop declaring them and export the symbols directly for compatability. Arguably they should be x86 only as they were never declared on other Tier-1 architectures. Reviewed by: imp, kib Differential Revision: https://reviews.freebsd.org/D46407

* Set LG_VADDR to 48 on RISC-V.Brooks Davis2020-05-041-1/+1
| | | | | | | | | | | | | | The Sv48 PTE format is the largest currently defined address space for RISC-V. It makes no sense to define a larger size and doing so (at least for 64-bits) forces rtrees down a slow path.

Before the jemalloc 5.0.0 update, all the TLS data in the i386 version of libc.so added up to 80 bytes (a multiple of 8), but 5.0.0 made this grow to 2404 bytes (not a multiple of 8). This is due to added caching data in jemalloc's internal struct tsd_s. To fix AddressSanitizer, ensure this struct is aligned to at least 16 bytes, which can be done unconditionally for all architectures. (An earlier version of the fix aligned the struct to 8 bytes, but only for ILP32 architectures. This was deemed unnecessarily complicated.)

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.
