usr.sbin/jls jls.c
Log:
Not sure why, but SYSCTL_OUT() can sometimes keep returning ENOMEM
in sysctl_jail_list(). Because of this, jls(8) could enter into
an endless loop. The strange thing is, that we can call jls(8) while
the other one is in loop and it will succeed - SYSCTL_OUT() will
not return ENOMEM there.
Maybe SYSCTL_OUT() returns first ENOMEM, because there is no memory,
but is marking some memory range as wired even on failure and another
SYSCTL_OUT() calls are not going to succeed, because process exceeds
limit of wired memory? ENOVMCLUE.
Anyway. Fix jls(8) to ignore ENOMEM and retry only 4 times.
