Weird. It just appears to be some networking modules, but not = others (in particular, if_bge, if_em, if_igb, if_re). if_firewire and = mpt_cam on the otherhand function as expected :/. Thanks, -Garrett= On Sun, Feb 03, 2013 at 04:37:23AM +0000, Garrett Cooper wrote:

Definitely not isolated to re(4), nor networking drivers alone.
gjb@nucleus:~ % kldstat -m acpi_asus
kldstat: can't find module acpi_asus: No such file or directory
gjb@nucleus:~ % kldstat -m geom_eli
kldstat: can't find module geom_eli: No such file or directory
gjb@nucleus:~ % kldstat | egrep "(acpi_asus|geom_eli)"

9 1 0xffffffff8138b000 8b10 acpi_asus.ko

Yeah.. it's a bit unexpected. I would need to do more digging, = but my guess is that it's an inconsistency in module naming and = representation as the loop I showed in the original bug report is simple = enough >_>=85 Thanks for the info though! -Garrett= State Changed From-To: open->closed Close: there is no bug For drivers using DRIVER_MODULE, the module name is #busname "/" #name so for instance pci/re % kldstat -m pci/re Id Refs Name 242 1 pci/re Responsible Changed From-To: freebsd-bugs->antoine Track |
Tried to use kldstat -m to determine whether or not a networking module is loaded, and FWIW it appears to not work as expected: $ kldstat Id Refs Address Size Name 1 30 0xffffffff80200000 91e2d8 kernel 2 1 0xffffffff80b1f000 264378 zfs.ko 3 5 0xffffffff80d84000 25e38 krpc.ko 4 2 0xffffffff80daa000 60d8 opensolaris.ko 5 1 0xffffffff80e12000 7afb aio.ko 6 1 0xffffffff80e1a000 a5bf if_re.ko 7 1 0xffffffff80e25000 303fd nfsd.ko 8 1 0xffffffff80e56000 110b8 nfscommon.ko 9 2 0xffffffff80e68000 3ff nfssvc.ko 10 2 0xffffffff80e69000 faf nfslock.ko 11 1 0xffffffff80e6a000 e235 nfslockd.ko 12 1 0xffffffff80e79000 2860a kqemu.ko $ kldstat -m if_re kldstat: can't find module if_re: No such file or directory $ kldstat -m kqemu Id Refs Name 198 1 kqemu $ kldstat -m re kldstat: can't find module re: No such file or directory Not sure why, but this code in kern_module appears to be broken, or just doesn't represent data consistent to expectations from the printouts provided by kldstat: From kern_module.c: 217 module_t 218 module_lookupbyname(const char *name) 219 { 220 module_t mod; 221 int err; 222 223 MOD_LOCK_ASSERT; 224 225 TAILQ_FOREACH(mod, &modules, link) { 226 err = strcmp(mod->name, name); 227 if (err == 0) 228 return (mod); 229 } 230 return (NULL); 231 } From if_re.c: 337 DRIVER_MODULE(re, pci, re_driver, re_devclass, 0, 0); I've seen similar issues with bge(4) on a work machine, so I don't think it's isolated to re(4)... How-To-Repeat: kldstat -m if_<foo>
