Hi,
It seems if one has
pseudo-device ksyms # /dev/ksyms
in one's kernel, netstat refuses to play:
# netstat
netstat: no namelist
If I take just the above line from the kernel definition, it works
fine. The ktruss output shows opening of /dev/ksyms if the option is
enabled, but fails further:
...
12117 1 netstat open("/dev/kmem", 0, 0) =3D 5
12117 1 netstat fcntl(0x5, 0x2, 0x1) =3D 0
12117 1 netstat open("/dev/drum", 0, 0) =3D 6
12117 1 netstat fcntl(0x6, 0x2, 0x1) =3D 0
12117 1 netstat open("/dev/ksyms", 0, 0) =3D 7
12117 1 netstat fcntl(0x7, 0x2, 0x1) =3D 0
12117 1 netstat close(0x7) =3D 0
12117 1 netstat getgid() =3D 0, 2
12117 1 netstat setgid(0) =3D 0
12117 1 netstat open("/dev/ksyms", 0, 0) =3D 7
12117 1 netstat fcntl(0x7, 0x2, 0x1) =3D 0
12117 1 netstat pread(0x7, 0xbfbfaf90, 0x20, 0, 0, 0) =3D 32
"\^?ELF\^A\0\0\0\0\0\0\0\0\0\0\0\^B\0\0\0\^A\0\0\0\0\0\0\0004\0\0\0"
12117 1 netstat __fstat30(0x7, 0xbfbfdf40) =3D 0
12117 1 netstat pread(0x7, 0xbfbfdf00, 0x34, 0, 0, 0) =3D 52
"\^?ELF\^A\0\0\0\0\0\0\0\0\0\0\0\^B\0\0\0\^A\0\0\0\0\0\0\0004\0\0\0t=
\0"
12117 1 netstat close(0x7) =3D 0
12117 1 netstat write(0x2, 0xbfbfd6d0, 0x9) =3D 9
"netstat: "
12117 1 netstat write(0x2, 0xbfbfd6f0, 0xb) =3D 11
"no namelist"
12117 1 netstat write(0x2, 0x8068f5b, 0x1) =3D 1
"\n"
12117 1 netstat exit(0x1)
.....
Obviously with no ksyms in the kernel, it cannot open /dev/ksyms and
carries on it's work.
Any ideas?
(BTW this is -current from yesterday, i386).
