With this switch processes (such as xconsole) can open /dev/console
without breaking login on the text or serial console. This can be
trivially triggered by enabling xdm in rc.conf and hitting
Ctrl+Alt+F1 or equivalent once booted.
The changes:
- Add entry for /dev/console or /dev/constty if missing
- If a port's had /dev/console 'on' switch it off and enable /dev/constty
- If a port did not have /dev/console 'on', leave /dev/constty off
Some ports had /dev/console off and /dev/ttyE0 enabled, presumably to
avoid just this issue. It may make sense to adjust these also (but not
in this pass)
As discussed on current-users
The original code initialized each component in non-init functions such as
arp_dad_start and nd6_dad_find, conditionally based on a global flag for each.
However, it was racy because the flag and the code around it were not
protected by a lock and could cause a kernel panic at worst.
Fix the issue by initializing the components in bootup as usual.
A lot of files are now living outside of dist, since they're not in the
distributed sources: they're generated, usually by python/meson.
The remaining changes are due to files being moved around.
Do so, so we don't rely on the build machine to have <endian.h> for
this macro check.
Using ${CPPFLAGS} rather than my own encoding of --sysroot, since it
already includes it.
Tested by agc, thanks.
This change allows to pick code paths in the kernel that are tuned for
alignment sensitive (and stricted in C meaning) code paths. In particular
the IPv6 code uses this heavily and skips whenever possible the process
of aligning of networking data.
With this modification all ATF tests are executed on amd64 without
triggering any UBSan reports in dmesg.
In theory __NO_STRICT_ALIGNMENT could be tuned for vax and m68k, however
these machines are still unsupported in LLVM sanitizers and syzkaller.
