Newlib shares large parts of <sys/cdefs.h> with FreeBSD and received
this bug report:
https://sourceware.org/pipermail/newlib/2023/020400.html
As an extension, GCC and clang offer C99-style restricted pointers in
C++ mode:
https://gcc.gnu.org/onlinedocs/gcc/Restricted-Pointers.html
We notice that this extension is broken when including newlib headers:
restricted pointers are treated as ordinary pointers.
We traced this to the following section of
newlib/libc/include/sys/cdefs.h:
/*
* GCC 2.95 provides `__restrict' as an extension to C90 to support the
* C99-specific `restrict' type qualifier. We happen to use `__restrict' as
* a way to define the `restrict' type qualifier without disturbing older
* software that is unaware of C99 keywords.
*/
#if !(__GNUC__ == 2 && __GNUC_MINOR__ == 95)
#if !defined(__STDC_VERSION__) || __STDC_VERSION__ < 199901
#define __restrict
#else
#define __restrict restrict
#endif
#endif
While the GCC __restrict extension was indeed introduced in GCC 2.95, it
is not limited to this version; the extension is also not limited to
C90:
https://gcc.gnu.org/gcc-2.95/c++features.html
Rewrite the logic in the header so that __restrict is kept alone when
available.

By not exporting _start, we get various warnings of the form:
ld: warning: cannot find entry symbol _start
Note that in practice these don't matter because we manually construct
our PE header and use objcopy -O binary, so the entry point is set to
whatever we put explicitly in the PE header, but we should still do the
right thing and silence these warnings.
This was found in CheriBSD, where bsd.prog.mk has similar logic to
bsd.lib.mk and sets -Wl,--(no-)fatal-warnings based on LD_FATAL_WARNINGS
(unlike FreeBSD which only does so in the latter).
Verify that the requested region of the mbuf chain is not beyond the
end of the chain before trimming it from the end. If it is out of
bounds, fail with an error (EPROTO).
While here, properly handle the case that the amount of data at the
end of the chain might span more than one mbuf by using m_adj to drop
the extra bytes rather than assuming m_len of the last mbuf can be
adjusted directly.

ISO9660 permits specifying a logical block size that is any power of 2
greater than or equal to 512. The geom disk layer requires requests
to be aligned on sector boundaries of the provider. With a volume
that uses a logical block size smaller than the underlying disk sector
size (e.g. a logical block size of 512 or 1024 on a CD which uses 2048
byte sectors), the current cd9660 vfs can issue requests for partial
sectors, or on non-sector boundaries.
Fixing this properly would require wrapping all of the calls to
bread*/bwrite* in cd9660 vfs to roundup requests to be on sector
boundaries which can include both the length, but also the starting
sector number (and thus requiring use of an offset relative to b_data
in the resulting buf).
These images do not seem to be common however given that no one has
fixed this in cd9660's vfs in the past few decades, so just reject
them during mount with an error. If such images are found to be used
in the wild in practice, then the larger fix can be applied.

Previously a debug kernel would trigger an assertion failure if an I/O
request attempted to read off the end of a concat volume, but a
non-debug kernel would use an invalid sub-disk to try to complete the
request eventually resulting in some sort of fault in the kernel.
Instead, turn the assertions into explicit checks that fail requests
beyond the end of the volume with EIO. For requests which run over
the end of the volume, return a short request.

Because KASAN shadows the kernel image itself (KMSAN currently does
not), a shadow mapping of the boot stack must be created very early
during boot. pmap_san_enter() reserves a fixed number of pages for the
purpose of creating and mapping this shadow region.
After commit 789df254cc ("amd64: Use a larger boot stack"), it could
happen that this reservation is insufficient; this happens when
bootstack crosses a PAGE_SHIFT + KASAN_SHADOW_SCALE_SHIFT boundary.
Update the calculation to take into account the new size of the boot
stack.

Send an ICMPv6 echo request packet with multiple IPv6 fragment headers.
Set rules to pass all packets, except for ICMPv6 echo requests.
pf ought to drop the echo request, but doesn't because it reassembles

words: it fails to detect the ICMPv6 echo header.

With 'scrub fragment reassemble' if a packet contains multiple IPv6
fragment headers we would reassemble the packet and immediately
continue processing it.
That is, we'd remove the first fragment header and expect the next
header to be a final header (i.e. TCP, UDP, ICMPv6, ...). However, if
it's another fragment header we'd not treat the packet correctly.
That is, we'd fail to recognise the payload and treat it as if it were
an IPv6 fragment rather than as its actual payload.
Fix this by restarting the normalisation on the reassembled packet.
If there are multiple fragment headers drop the packet.

On Linux these system calls have an effect only when used in conjuction
with an I/O scheduler that supports I/O priorities. If no I/O scheduler
has been set for a thread, then by defaut the I/O priority will follow
the CPU nice value. Due to FreeBSD lack of I/O scheduler facilities, the
default Linux behavior is implemented.
