FPU state of the lwp right away during context switches. This guarantees
that when the CPU executes in userland, the FPU doesn't contain secrets.
Maybe we also need to clear the FPU in setregs(), not sure about this one.
Can be enabled/disabled via:
machdep.fpu_eager = {0/1}
Not yet turned on automatically on affected CPUs (Intel Family 6).
More generally it would be good to turn it on automatically when XSAVEOPT
is supported, because in this case there is probably a non-negligible
performance gain; but we need to fix PR/52966.
On 64-bit machines struct timespec50 has padding between 32-bit tv_sec
and long tv_nsec that is not affected by normal assignment. Scrub it.
The result is most likely about to be passed to the user space by the
caller, so do it here to take care of them all.
The list named ifv_mc_listhead saves multicast addresses that
are added through SIOCADDMULTI. Each nodes added to the list
are used for deleting the related address from a parent I/F
when remove the configuration of parent I/F.
In carp(4) and OpenBSD's vlan(4), the lists is used to check
a parameter of SIOCDELMULTI in addition to the use.
Based on them, the check is added to vlan(4)
ok ozaki-r@
cosmetics, stuff we already had, or stuff which does not apply due
to different frameworks):
- Add support for fiber on 88E8021/22
- Avoid unnecessary resets. This should make fiber 88E8021/22 work completely
- Only probe phy's at address 0; gets rid of bogus phy's on the
Marvell Yukon 88E8036
- Remove an unused function msk_setfilt() which was copied from sk(4)
- Make msk(4) detachable
- Simplify the combination use of pci_mapreg_type()/pci_mapreg_map()
Replace homegrown logic of calculating alignment with alignof, a C11 header
feature.
Add a check for NetBSD >= 8.0 just in case that someone will want to build
it on older NetBSD.
Issue detected with UBSan.
The sanitizers are designed to use pristine OS versions of these libraries,
install interceptors for public symbols in them and link with them in every
sanitized executable.
Having unmodified base libraries (c, m, rt, pthread) also makes the system
usable with programs linking with them and without sanitization, as there
are no fatal issues during the resolving of missing symbols.
The remaining libraries like libutil, libintl etc are prebuilt with
sanitization and all their users in the MKSANITIZER=yes distribution are
required to use the same sanitizer.
libc and libpthread are already marked with the NOSANITIZER flag.
Comment here already says it isn't necessary and will be removed.
Hasten the process for us and avoid the problematic typedef.
This is useful because u_longlong_t would otherwise need to be
provided by compat headers.
We switched to Fast IPsec at NetBSD 6.0 and that's the IPsec implementation of
us now. So we don't need to have a separate manual. Merge fast_ipsec.4 into
ipsec.4 and remove fast_ipsec.4.
On 64-bit machines struct timespec50 has padding between 32-bit tv_sec
and long tv_nsec that is not affected by normal assignment. Scrub it
before we uiomove struct owscons_event.
