When we create a new state for multihomed sctp connections (i.e.
based on INIT/INIT_ACK or ASCONF parameters) we cannot know what

6 months agoEnsure I/O buffers in libufs(3) are 128-byte aligned.
Kirk McKusick [Fri, 17 Nov 2023 22:10:29 +0000 (14:10 -0800)]
Ensure I/O buffers in libufs(3) are 128-byte aligned.

Various disk controllers require their buffers to be aligned to a
cache-line size (128 bytes). For buffers allocated in structures,
ensure that they are 128-byte aligned. Use aligned_malloc to allocate
memory to ensure that the returned memory is 128-byte aligned.

While we are here, we replace the dynamically allocated inode buffer
with a buffer allocated in the uufsd structure just as the superblock
and cylinder group buffers do.

This can be removed if/when the kernel is fixed. Because this problem
has existed on one I/O subsystem or another since the 1990's, we
are probably stuck with dealing with it forever.

The problem most recent showed up in Azure, see:
    https://reviews.freebsd.org/D41728
    https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=267654
Before these fixes were applied, it was confirmed that the changes
in this commit also fixed the issue in Azure.

sys: Disable -Walloc-size-larger-than for GCC 9+

By default this warns about sizes larger than PTRDIFF_MAX passed to
malloc (rather than SIZE_MAX).  This doesn't trigger
deterministically, but it does trigger for kmalloc() of struct_size()
in iwlwifi's iwl_configure_rxq even when struct_size() is changed to
use PTRDIFF_MAX.  NB: struct_size() in Linux caps the size at
SIZE_MAX, not PTRDIFF_MAX via size_mul().

L2ARC: Restrict write size to 1/4 of the device

PR #15457 exposed weird logic in L2ARC write sizing. If it appeared
bigger than device size, instead of liming write it reset all the
system-wide tunables to their default.  Aside of being excessive,
it did not actually help with the problem, still allowing infinite
loop to happen.

This patch removes the tunables reverting logic, but instead limits
L2ARC writes (or at least eviction/trim) to 1/4 of the capacity.
