nvme-multipath: set BLK_FEAT_ZONED only after the zone info is known
In the Linux kernel, the following vulnerability has been resolved: nvme-multipath: set BLK_FEAT_ZONED only after the zone info is known The namespace head is marked zoned at allocation time based only on the command set identifier. If the zone info query reports a zero zone size, the path namespace is registered without zoned limits while the head still advertises the zoned capability with a zone size of zero, and reporting zones or writing to the head then shifts by ilog2(0). Drop the zoned feature from the head allocation and let the head limits refresh stack it in from the path namespace instead.
