On 14-STABLE:
% ipcs
ipcs: sysctlbyname: kern.ipc.msgmax: No such file or directory
Is this known bug? Intentional? Known fix?
Additional info:
sysctl oid mentioned indeed does not exist on 14-STABLE, more oids
missing, compare on 13-STABLE
% sysctl kern.ipc | wc -l
54
with that on 14-STABLE
% sysctl kern.ipc | wc -l
40
One difference - on 13-STABLE, SysV shared memory support is in kernel,
in 14-STABLE, sysvshm.ko module is being loaded to provide support, it
just looks probably not relevant to the issue I see, I just can't
verify it now.
At the moment, I can't test it on 15-CURRENT.
Regards,
Milan
