PCI: endpoint: Fix swapped parameters in pci_{primary/secondary}_epc_epf_unlink() functions
In the Linux kernel, the following vulnerability has been resolved: PCI: endpoint: Fix swapped parameters in pci_{primary/secondary}_epc_epf_unlink() functions struct configfs_item_operations callbacks are defined like the following: int (*allow_link)(struct config_item *src, struct config_item *target); void (*drop_link)(struct config_item *src, struct config_item *target); While pci_primary_epc_epf_link() and pci_secondary_epc_epf_link() specify the parameters in the correct order, pci_primary_epc_epf_unlink() and pci_secondary_epc_epf_unlink() specify the parameters in the wrong order, leading to the below kernel crash when using the unlink command in configfs: Unable to handle kernel paging request at virtual address 0000000300000857 Mem abort info: ... pc : string+0x54/0x14c lr : vsnprintf+0x280/0x6e8 ... string+0x54/0x14c vsnprintf+0x280/0x6e8 vprintk_default+0x38/0x4c vprintk+0xc4/0xe0 pci_epf_unbind+0xdc/0x108 configfs_unlink+0xe0/0x208+0x44/0x74 vfs_unlink+0x120/0x29c __arm64_sys_unlinkat+0x3c/0x90 invoke_syscall+0x48/0x134 do_el0_svc+0x1c/0x30prop.0+0xd0/0xf0 [mani: cced stable, changed commit message as per https://lore.kernel.org/linux-pci/aV9joi3jF1R6ca02@ryzen]
