Hi,
On today's next (next-20190118) my Colibri VF50 board fails to boot up
from network (DHCP, NFSv4 root). Looks like missing network adapter.
Expected:
[ 3.041773] Micrel KSZ8041 400d1000.ethernet-1:00: attached PHY driver
[Micrel KSZ8041] (mii_bus:phy_addr=400d1000.ethernet-1:00, irq=POLL)
Result:
[ 15.614964] Root-NFS: no NFS server address
[ 15.619353] VFS: Unable to mount root fs via NFS, trying floppy.
[ 15.626762] VFS: Cannot open root device "nfs" or unknown-block(2,0): error -6
[ 15.634252] Please append a correct "root=" boot option; here are the
available partitions:
[ 15.642791] 0100 16384 ram0
[ 15.642804] (driver?)
[ 15.649076] Kernel panic - not syncing: VFS: Unable to mount root fs
on unknown-block(2,0)
[ 15.657423] ---[ end Kernel panic - not syncing: VFS: Unable to mount
root fs on unknown-block(2,0) ]---

Full log and defconfig attached.
Board:
- Toradex Colibri VF50 on Iris board
ARMv7, UP, Cortext-A5, NXP VF500, 128 MB RAM, 128 MB NAND
Systemd: v232
DHCP, NFSv4 root
Best regards,
Krzysztof

I see now in the logs:
[ 2.436822] mdio_bus 400d1000.ethernet-1:00: error -2 loading PHY
driver module for ID 0x00221513
which is kind of misleading. There is no initramfs so there is no
usermod library at this point. It is not needed. This seems to break
all DHCP/NFS root boots without initrd/initramfs.
Best regards,
Krzysztof

Thanks for the report. Could you please provide your kernel config
and the syslog of a boot before or w/o the patch in question?
If you boot via nfs then I'd expect that the PHY driver is built-in and
not a module. Therefore it's not fully clear to me yet why
request_module() returns -ENOENT.

OK, I see. The -ENOENT could refer to the modprobe binary, not the PHY
driver module. Still it would be helpful to see the kernel config and
the requested log.

As I wrote - there is no initramfs so there is no modprobe binary
neither. The log and config were attached to the first email.

I'm seeing the same booting nfsroot on several Renesas boards.
E.g. on r8a7791/koelsch:
mdio_bus ee700000.ethernet-ffffffff:01: error -2 loading PHY
driver module for ID 0x00221537
sh-eth ee700000.ethernet: MDIO init failed: -2
This failure happens only when CONFIG_MODULES=y.
Reverting commit 13d0ab6750b20957 ("net: phy: check return code when
requesting PHY driver module") fixes the issue.
phy_request_driver_module() tries to load module
"mdio:00000000001000100001010100110111", which fails.
When CONFIG_MODULES=n, the error is ignored, and everything works fine.
0b00000000001000100001010100110111 == 0x00221537 == PHY_ID_KSZ8041RNLI,
which is served by drivers/net/phy/micrel.c.
Interestingly, CONFIG_MICREL_PHY=y, so I'm wondering why the PHY subsystem
tries to load a module for a driver which is already present in the first
place?
Oh, the following comment tries to explain:
/* Request the appropriate module unconditionally; don't
* bother trying to do so only if it isn't already loaded,
* because that gets complicated. A hotplug event would have
* done an unconditional modprobe anyway.
Hence request_module() failures are normal.
ret = request_module(MDIO_MODULE_PREFIX MDIO_ID_FMT,
MDIO_ID_ARGS(phy_id));
/* we only check for failures in executing the usermode binary,
* not whether a PHY driver module exists for the PHY ID
*/
if (IS_ENABLED(CONFIG_MODULES) && ret < 0) {
phydev_err(dev, "error %d loading PHY driver module for
ID 0x%08x\n",
ret, phy_id);
return ret;
}
However:
/**
* __request_module - try to load a kernel module
* @wait: wait (or not) for the operation to complete
* @fmt: printf style format string for the name of the module
* @...: arguments as specified in the format string
*
* Load a module using the user mode module loader. The function returns
* zero on success or a negative errno code or positive exit code from
* "modprobe" on failure.
So perhaps the check should be for "ret > 0"?

Hi Geert,
There is a follow up patch:
