[libunwind][PAC] Defang ptrauth's PC in valid CFI range abort
It turns out making the CFI check a release mode abort causes many,
if not the majority, of JITs to fail during unwinding as they do not
set up CFI sections for their generated code. As a result any JITs
that do nominally support unwinding (and catching) through their JIT
or assembly frames trip this abort.

[libc++] Don't double-wrap iterators when bounded iterators are used (#182264)
There is no reason to double-wrap iterators, since we can already
achieve anything we want within `__bounded_iter`itself.
This is technically ABI breaking, but people using bounded iterators
shouldn't require ABI stability currently.
Fixes #178521
textproc/groff: Clean and improve the port
* Define directory layout directly via MAKE_ARGS instead of working
around predefined defaults via post-install stances.

devel/p5-Dist-Build: Modern perl module builder
Dist::Build is a new perl module builder - with Build.PL as a starting point.
Dist::Build comes from the author of Module::Build and of Module::Build::Tiny.
This new port is needed as a dependency for ver.0.030 of the existing port security/p5-Crypt-Argon2.

uuidgen: generate UUIDs in bounded batches to respect kernel limit
The uuidgen(2) system call enforces a hard upper limit of 2048 UUIDs per
invocation. uuidgen(1) previously attempted to generate arbitrary counts
in a single call and allocated memory accordingly, leading to EINVAL
errors, unnecessary memory usage, and potential overflow risks.
Generate UUIDs in fixed-size batches, streaming output incrementally
while preserving existing semantics. Mirror the kernel limit explicitly
since it is not exposed via a public interface.

rc.d/zfs: align zfs mount verbosity in host and jail environments
ZFS script runs different startup seqneces depending on where it runs:
on the host (`zfs_start_main()`) or in a jail (`zfs_start_jail()`):
- `zfs_start_main()` mounts ZFS datasets in verbose mode `zfs mount -va`
- `zfs_start_jail()` mounts ZFS datasets silently `zfs mount -a`.
This change aligns the verbose levels.

fsck_msdosfs: reduce the scope of dentry deletion
When dentry flag is ATTR_VOLUME because of 1 bit flip(from 0x10 to 0x18),
removede function will delete all dentry from invalid dentry postion,
so some normal dentries will be deleted in the same cluster.Unfortunately,
these normal directories and files will not be visible to the user
after wo do fsck_msdos

Add .editorconfig
FreeBSD developers use different text editors or sometimes use GUI
editors such as VSCode or Zed on different platforms for convinence.
However, there is lack of unified config for those editors to follow
style(9) including indent rules.
Although most "modern" editors support .editorconfig out of box, basic
editors such as vim needs a plugin for autoloading .editorconfig file.

[CIR] Add Commutative/Idempotent traits to binary ops
Add missing MLIR traits to CIR binary operations, matching the arith
dialect conventions:
- AndOp, OrOp: Commutative, Idempotent (fixes FIXME)
- AddOp, MulOp, XorOp, MaxOp: Commutative
Add these ops to the CIRCanonicalize pass op list so trait-based
folding is exercised by applyOpPatternsGreedily.
Update testFloatingPointBinOps in binop.cpp to use computed values,
preventing DCE of the now-canonicalized ops.
[ubsan_minimal] Build on Solaris (#184976)
Two tests currently `FAIL` on Solaris/amd64 and Solaris/sparcv9:
```
SafeStack-Standalone-i386 :: overflow.c
SafeStack-Standalone-x86_64 :: overflow.c
```
This happens because `libclang_rt.ubsan_minimal.a` isn't built on
Solaris although it's required with `-fsanitize-minimal-runtime`.
This patch fixes this.
Tested on `amd64-pc-solaris2.11` and `sparcv9-sun-solaris2.11`.
zlib: fix heap info leak in deflateCopy (ZLB-01-005)

Author: Mark Adler <git at madler.net>
Date: Sat Jan 10 21:34:20 2026 -0800
Copy only the initialized deflate state in deflateCopy.
To avoid the propagation and possible disclosure of uninitialized
memory contents.
