Descripción

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: phy: don&amp;#39;t try to setup PHY-driven SFP cages when using genphy<br /> <br /> We don&amp;#39;t have support for PHY-driver SFP cages with the genphy code.<br /> <br /> On top of that, it was found by sashiko that running<br /> sfp_bus_add_upstream() for genphy deadlocks, as for genphy the PHY<br /> probing runs under RTNL, which isn&amp;#39;t the case for non-genphy drivers.<br /> <br /> This problem was reproduced, and does lead to a deadlock on RTNL.<br /> <br /> Before the blamed commit, the phy_sfp_probe() call was made by<br /> individual PHY drivers, so there was no way to get to the SFP probing<br /> path when using genphy.<br /> <br /> Let&amp;#39;s therefore only run phy_sfp_probe when not using genphy.
