The “update cache versions without reset” sysfs reset operation (0x20261)
\ncalls get_flash_version(), which reads hardware flash registers, without
\nholding ha->optrom_mutex. The VPD update path serializes the same call
\nunder optrom_mutex, so this reset path can interleave its flash register
\naccesses with a concurrent VPD or optrom flash operation and corrupt the
\nreads.<\/p>\n
Hold ha->optrom_mutex across the get_flash_version() call to match the
\nVPD update path.<\/p>\n","protected":false},"excerpt":{"rendered":"
