config SECURITY_LOADPIN bool "Pin load of kernel files (modules, fw, etc) to one filesystem" depends on SECURITY && BLOCK help Any files read through the kernel file reading interface (kernel modules, firmware, kexec images, security policy) can be pinned to the first filesystem used for loading. When enabled, any files that come from other filesystems will be rejected. This is best used on systems without an initrd that have a root filesystem backed by a read-only device such as dm-verity or a CDROM. config SECURITY_LOADPIN_ENABLED bool "Enforce LoadPin at boot" depends on SECURITY_LOADPIN help If selected, LoadPin will enforce pinning at boot. If not selected, it can be enabled at boot with the kernel parameter "loadpin.enabled=1". logo'/> index : net-next.git

PCI/MSI: Don't apply affinity if there aren't enough vectors left
Bart reported a problem wіth an out of bounds access in the low-level IRQ affinity code, which we root caused to the qla2xxx driver assigning all its MSI-X vectors to the pre and post vectors, and not having any left for the actually spread IRQs. Fix this issue by not asking for affinity assignment when there are no vectors to assign left.
