vfs_aio_ratelimit: Add per-share TDB persistence for local rate limiter state

2026-02-27T10:49:41+00:00

Introduce local TDB storage for saving and restoring ratelimiter state
(iops_tokens, bytes_tokens, last timestamp). Each share now persists
its read/write limiter state under aio_ratelimit.tdb.

Added VERSION pseudo-key for schema versioning

On disconnect, save the latest state and close TDB.

lib:replace: Implement memset_explicit()

2025-11-11T13:46:42+00:00

The memset_s() implementation is a bit obscure, as it requires a
constraint handler to be set up. You don't really find any
implmentations out there.

With C23 memset_explicit() was added and this has been implemented
for glibc 2.43 and also in FreeBSD.

remove usage of bzero

2025-01-02T17:01:30+00:00

bzero() function has been deprecated for a long time.
In samba it is replaced with memset().  But samba also
provides common memory-zeroing macros, like ZERO_STRUCT().
In all places where bzero() is used, it actually meant to
zero a structure or an array.

So replace these bzero() calls with ZERO_STRUCT() or
ZERO_ARRAY() as appropriate, and remove bzero() replacement
and testing entirely.

While at it, also stop checking for presence of memset() -
this function is standard for a very long time, and the
only conditional where HAVE_MEMSET were used, was to
provide replacement for bzero() - in all other places
memset() is used unconditionally.

FICLONERANGE was introduced in kernel version 4.5, so I guess we can just assume
it is present if HAVE_LINUX_IOCTL is defined.
