Currently, this driver returns an error code (-1) from the ioctl call, which causes dhcpcd to assume that the device is not a wireless interface and therefore it fails to work correctly with it thereafter.

Piccoli" <gpiccoli(a)linux.vnet.ibm.com> [ Upstream commit e4717292ddebcfe231651b5aff9fa19ca158d178 ] As part of the scsi EH path, aacraid performs a reinitialization of the adapter, which encompass freeing resources and IRQs, NULLifying lots of pointers, and then initialize it all over again. We've identified a problem during the free IRQ portion of this path if CONFIG_DEBUG_SHIRQ is enabled on kernel config file. Happens that, in case this flag was set, right after free_irq() effectively clears the interrupt, it checks if it was requested as IRQF_SHARED. In positive case, it performs another call to the IRQ handler on driver. Problem is: since aacraid currently free some resources *before* freeing the IRQ, once free_irq() path calls the handler again (due to CONFIG_DEBUG_SHIRQ), aacraid crashes due to NULL pointer dereference with the following trace: aac_src_intr_message+0xf8/0x740 [aacraid] __free_irq+0x33c/0x4a0 free_irq+0x78/0xb0 aac_free_irq+0x13c/0x150 [aacraid] aac_reset_adapter+0x2e8/0x970 [aacraid] aac_eh_reset+0x3a8/0x5d0 [aacraid] scsi_try_host_reset+0x74/0x180 scsi_eh_ready_devs+0xc70/0x1510 scsi_error_handler+0x624/0xa20 This patch prevents the crash by changing the order of the deinitialization in this path of aacraid: first we clear the IRQ, then we free other resources.

It seems that we can simply enlarge the MAX_ACTIONS_BUFSIZE to fix it, but this is not the root cause. For example, for a vxlan output action, we need about 60 bytes for the nlattr, but after it is converted to the flow action, it only occupies 24 bytes. This means that we can still support more than 1000 vxlan output actions for a single datapath flow under the the current 32k max limitation. So even if the nla_len(attr) is larger than MAX_ACTIONS_BUFSIZE, we shouldn't report EINVAL and keep it move on, as the judgement can be done by the reserve_sfa_size.
