Move from the v2.2.y stable branch to the v2.3.y line (tag v2.3.1,
2026-06-19). v2.3.x carries all v2.2.6..v2.2.16 backports plus the
2.3.0 rework.
Security:
* CVE-2026-55392: validate s_log_block_size in nilfs_sb_is_valid().
A crafted NILFS2 image with s_log_block_size > 6 caused oversized
shifts / huge allocations in nilfs-tune, dumpseg and any tool
reading a device.
2.3.0 highlights:
* Utilities (lscp, lssu, nilfs-clean, ...) accept file/directory
arguments and auto-resolve the backing device.
* cleanerd: cap segments per cleaning step by free segments (avoids
stalling near ENOSPC) and against 32-bit size_t overflow; clean
SIGINT exit, SIGUSR1 state dump.
* Library refactor with an API/ABI break: obsolete APIs and internal
structs removed from public headers, new segment I/O / resize /
freeze-thaw APIs, types unified to uint32_t/uint64_t/bool.
* mkfs.nilfs2 sets the block-count read-only-compat flag by default.
Packaging-relevant build-system changes:
* Soname bump libnilfs/libnilfsgc 2 -> 3; libnilfscleaner is no longer
a shared library (now an internal convenience lib), so
libnilfscleaner.so.* correctly disappears from the runtime package.
* New pkg-config producer files (nilfs.pc, nilfsgc.pc) land in
${libdir}/pkgconfig -> require inherit pkgconfig.
* LT_INIT([disable-static]) means static libs are no longer installed.
* The old --with-base-sbindir knob was replaced upstream by an
--enable-usrmerge=(no|sbin|bin|auto) mechanism. Drop the local
0001-configure.ac-Add-knob-to-define-base-sbindir.patch and select
the hierarchy explicitly from DISTRO_FEATURES, because the "auto"
default probes the build host and is wrong when cross compiling.
LDCONFIG=true is still required.
