The status of SAS PHY is in sas_phy->enabled. There is an issue that the status of a remote SAS PHY may be initialized incorrectly: if disable remote SAS PHY through sysfs interface (such as echo 0 > /sys/class/sas_phy/phy-1:0:0/enable), then reboot the system, and we will find the status of remote SAS PHY which is disabled before is 1 (cat /sys/class/sas_phy/phy-1:0:0/enable). But actually the status of remote SAS PHY is disabled and the device attached is not found. In SAS protocol, NEGOTIATED LOGICAL LINK RATE field of DISCOVER response is 0x1 when remote SAS PHY is disabled. So initialize sas_phy->enabled according to the value of NEGOTIATED LOGICAL LINK RATE field. Signed-off-by:

The intend purpose here was to goto out if smp_execute_task() returned error. Obviously something got screwed up. We will never get these link error statistics below: ~:/sys/class/sas_phy/phy-1:0:12 # cat invalid_dword_count 0 ~:/sys/class/sas_phy/phy-1:0:12 # cat running_disparity_error_count 0 ~:/sys/class/sas_phy/phy-1:0:12 # cat loss_of_dword_sync_count 0 ~:/sys/class/sas_phy/phy-1:0:12 # cat phy_reset_problem_count 0 Obviously we should goto error handler if smp_execute_task() returns non-zero.

We've got a memory leak with the following producer: while true; do cat /sys/class/sas_phy/phy-1:0:12/invalid_dword_count >/dev/null; done The buffer req is allocated and not freed after we return. Fix it. Fixes: 2908d778 ("[SCSI] aic94xx: new driver") Signed-off-by:

The battery in my HP NetRAID-4M died of old age, and the aacraid driver started oopsing with NULL pointer dereference on startup after that. Fix it by reordering the init sequence to fill in function pointers before ioremapping memory, or dev->a_ops.adapter_ioremap pointer will be NULL. Other subtypes of aacraid seem to have the order already correct. This was the call trace: ? aac_probe_one+0x7a5/0xb30 [aacraid] pci_device_probe+0xc0/0x1a0 driver_probe_device+0x1df/0x3b0 __driver_attach+0xa9/0xe0 ? driver_probe_device+0x3b0/0x3b0 bus_for_each_dev+0x4c/0x90 driver_attach+0x1d/0x40 ? driver_probe_device+0x3b0/0x3b0 bus_add_driver+0x1a7/0x2a0 driver_register+0x6e/0x130 __pci_register_driver+0x54/0x90 ? 0xf81f4000 aac_init+0x2b/0x1000 [aacraid] do_one_initcall+0x45/0x1e0 ? kfree_skbmem+0x74/0xa0 ? kfree+0x16d/0x240 ? kvfree+0x45/0x50 ? kvfree+0x45/0x50 ? __vunmap+0x99/0x120 ? do_init_module+0x1a/0x245 do_init_module+0x83/0x245 load_module+0x2764/0x34a0 ? kernel_read_file+0x150/0x320 SyS_finit_module+0x82/0xa0 do_fast_syscall_32+0xba/0x340 Signed-off-by:

When connection type is N_Port to N_Port (point-to-point), there is a possibilty where initiator will not send PLOGI request and will directly send PRLI. In N2N connection the port has higher port name sends the PLOGI but not allow to send PRLI if is a target mode. Only initiator is allowed to send PRLI. Current driver code deletes old session when it receives PLOGI request. If we will not receive PLOGI request then we will not delete old session and create new session. Add check for N2N with PRLI receive only and trigger cleanup. For this case, the cleanup requires individual cmd abort instead of using implicit logout as a broad stroke flush. Signed-off-by:

The logo ELS command allocates dma coherent memory for the data payload and serialize the completions. When this command times out, the timeout routine completes the thread waiting for completion which in turn cleanup resources allocated for this ELS command processing. Don't call generic sp->free routine when this ELS command times out to avoid to double freeing of the same resources. Signed-off-by:
