Hi,
I recently installed latest -current snapshot of arm64 using
qemu-system-aarch64 -M virt.
$ doas what /bsd
/bsd
OpenBSD 6.2-current (GENERIC) #160: Wed Jan 24 18:26:59 MST 2018
But the system is relatively unstable due to random segfaults/abort on
almost any userland program (triggered on: sshd, smtpd, tmux, ksh,
clang, make, perl, rsync, ...)
Error types are:
- Segfaults
# rcctl ls failed
Segmentation fault (core dumped)
- Some are abort from libc:
$ cc ...
cc(19957) in free(): use after free 0x127e4b2f60
Abort trap
(during boot)
kvm_mkdb(90892) in free(): bogus pointer (double free?)
0xffffffffffffffff
- Random ssh connect problems (could be sshd segfault):
amd64$ ssh qaarch64
ssh_dispatch_run_fatal: Connection to 192.168.92.18 port 4422:
incorrect signature
amd64$ ssh qaarch64
ssh_exchange_identification: Connection closed by remote host
- Things that looks like memory corruption ?
$ doas rcctl enable accounting
/usr/sbin/rcctl: 89{m_base_accounting}: not found
/usr/sbin/rcctl[613]: YEL
: bad number
$ cc ...
cc: error: no such file or directory: '႕G'-hB/src/lib/libc'
(and re-running the command make it works)
- memory related kernel messages:
uvn_flush: obj=0x0, offset=0x10056b000. error during pageout.
uvn_flush: WARNING: changes to page may be lost!
(note: the system showed a serie of such message with changed
offset, and next was usable. In doubt, I rebooted)
Does the snapshot has know problem ? or it should be problem inside
qemu ?
Due to the ubiquious nature of the problem, it seems to me it could be
inside:
- qemu
- kernel
- libc
dmesg below (I disabled psci to avoid a panic at boot - jsg@ has
provided a proper bug report).
Thanks.
