Niklas Söderlund 569bf6d481 net: phy: Check for read errors in SIOCGMIIREG ... When reading registers from the PHY using the SIOCGMIIREG IOCTL any errors returned from either mdiobus_read() or mdiobus_c45_read() are ignored, and parts of the returned error is passed as the register value back to user-space. For example, if mdiobus_c45_read() is used with a bus that do not implement the read_c45() callback -EOPNOTSUPP is returned. This is however directly stored in mii_data->val_out and returned as the registers content. As val_out is a u16 the error code is truncated and returned as a plausible register value. Fix this by first checking the return value for errors before returning it as the register content. Before this patch, # phytool read eth0/0:1/0 0xffa1 After this change, $ phytool read eth0/0:1/0 error: phy_read (-95) Signed-off-by: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se> Reviewed-by: Florian Fainelli <florian.fainelli@broadcom.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Reviewed-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Tested-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Link: https://patch.msgid.link/20240903171536.628930-1-niklas.soderlund+renesas@ragnatech.se Signed-off-by: Jakub Kicinski <kuba@kernel.org>		2024-09-04 17:01:21 -07:00
