A long time ago the unfortunate decision was taken to add a self-deletion attribute to the sysfs SCSI device directory. That decision was unfortunate because self-deletion is really tricky. We can't drop that attribute because widely used user space software depends on it, namely the rescan-scsi-bus.sh script. Hence this patch that avoids that writing into that attribute triggers a deadlock. See also commit 7973cbd9fbd9 ("[PATCH] add sysfs attributes to scan and delete scsi_devices"). This patch avoids that self-removal triggers the following deadlock: ====================================================== WARNING: possible circular locking dependency detected 4.18.0-rc2-dbg+ #5 Not tainted ------------------------------------------------------ modprobe/6539 is trying to acquire lock: 000000008323c4cd (kn->count#202){++++}, at: kernfs_remove_by_name_ns+0x45/0x90 but task is already holding lock: 00000000a6ec2c69 (&shost->scan_mutex){+.+.}, at: scsi_remove_host+0x21/0x150 [scsi_mod] which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (&shost->scan_mutex){+.+.}: __mutex_lock+0xfe/0xc70 mutex_lock_nested+0x1b/0x20 scsi_remove_device+0x26/0x40 [scsi_mod] sdev_store_delete+0x27/0x30 [scsi_mod] dev_attr_store+0x3e/0x50 sysfs_kf_write+0x87/0xa0 kernfs_fop_write+0x190/0x230 __vfs_write+0xd2/0x3b0 vfs_write+0x101/0x270 ksys_write+0xab/0x120 __x64_sys_write+0x43/0x50 do_syscall_64+0x77/0x230 entry_SYSCALL_64_after_hwframe+0x49/0xbe -> #0 (kn->count#202){++++}: lock_acquire+0xd2/0x260 __kernfs_remove+0x424/0x4a0 kernfs_remove_by_name_ns+0x45/0x90 remove_files.isra.1+0x3a/0x90 sysfs_remove_group+0x5c/0xc0 sysfs_remove_groups+0x39/0x60 device_remove_attrs+0x82/0xb0 device_del+0x251/0x580 __scsi_remove_device+0x19f/0x1d0 [scsi_mod] scsi_forget_host+0x37/0xb0 [scsi_mod] scsi_remove_host+0x9b/0x150 [scsi_mod] sdebug_driver_remove+0x4b/0x150 [scsi_debug] device_release_driver_internal+0x241/0x360 device_release_driver+0x12/0x20 bus_remove_device+0x1bc/0x290 device_del+0x259/0x580 device_unregister+0x1a/0x70 sdebug_remove_adapter+0x8b/0xf0 [scsi_debug] scsi_debug_exit+0x76/0xe8 [scsi_debug] __x64_sys_delete_module+0x1c1/0x280 do_syscall_64+0x77/0x230 entry_SYSCALL_64_after_hwframe+0x49/0xbe other info that might help us debug this: Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(&shost->scan_mutex); lock(kn->count#202); lock(&shost->scan_mutex); lock(kn->count#202); *** DEADLOCK *** 2 locks held by modprobe/6539: #0: 00000000efaf9298 (&dev->mutex){....}, at: device_release_driver_internal+0x68/0x360 #1: 00000000a6ec2c69 (&shost->scan_mutex){+.+.}, at: scsi_remove_host+0x21/0x150 [scsi_mod] stack backtrace: CPU: 10 PID: 6539 Comm: modprobe Not tainted 4.18.0-rc2-dbg+ #5 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.0.0-prebuilt.qemu-project.org 04/01/2014 Call Trace: dump_stack+0xa4/0xf5 print_circular_bug.isra.34+0x213/0x221 __lock_acquire+0x1a7e/0x1b50 lock_acquire+0xd2/0x260 __kernfs_remove+0x424/0x4a0 kernfs_remove_by_name_ns+0x45/0x90 remove_files.isra.1+0x3a/0x90 sysfs_remove_group+0x5c/0xc0 sysfs_remove_groups+0x39/0x60 device_remove_attrs+0x82/0xb0 device_del+0x251/0x580 __scsi_remove_device+0x19f/0x1d0 [scsi_mod] scsi_forget_host+0x37/0xb0 [scsi_mod] scsi_remove_host+0x9b/0x150 [scsi_mod] sdebug_driver_remove+0x4b/0x150 [scsi_debug] device_release_driver_internal+0x241/0x360 device_release_driver+0x12/0x20 bus_remove_device+0x1bc/0x290 device_del+0x259/0x580 device_unregister+0x1a/0x70 sdebug_remove_adapter+0x8b/0xf0 [scsi_debug] scsi_debug_exit+0x76/0xe8 [scsi_debug] __x64_sys_delete_module+0x1c1/0x280 do_syscall_64+0x77/0x230 entry_SYSCALL_64_after_hwframe+0x49/0xbe See also https://www.mail-archive.com/linux-scsi@vger.kernel.org/msg54525.html.

Performance is affected when target queue depth is tracked. An atomic counter is incremented on the submission path which competes with it being decremented on the completion path. In addition, multiple CPUs can simultaniously be manipulating this counter for the same ndlp. Reduce the overhead by only performing the target increment/decrement when the target queue depth is less than the overall adapter depth, thus is actually meaningful.

Enabling list_debug showed the drivers txcmplq was suffering list corruption. The systems will eventually crash because the iocb free list gets crossed linked with the prings txcmplq. Most systems will run for a while after the corruption, but will eventually crash when a scsi eh reset occurs and the txcmplq is attempted to be flushed. The flush gets stuck in an endless loop. The problem is the abort handler does not hold the sli4 ring lock while validating the IO so the IO could complete while the driver is still preping the abort. The erroneously generated abort, when it completes, has pointers to the original IO that has already completed, and the IO manipulation (for the second time) corrupts the list. Correct by taking the ring lock early in the abort handler so the erroneous abort won't be sent if the io has/is completing.

Rename target_alloc_session to target_setup_session to avoid confusion with the other transport session allocation function that only allocates the session and because the target_alloc_session does so much more. It allocates the session, sets up the nacl and registers the session. The next patch will then add a remove function to match the setup in this one, so it should make sense for all drivers, except iscsi, to just call those 2 functions to setup and remove a session. iscsi will continue to be the odd driver.

There is an issue that link reset can't recover PHY when STP link timeout. Because current process of enabling PHY for v3 hw will wait last transmission done. The time of one transmission depends IO size, disk model and so on. Normally, it should be shorter than 50ms. But the last transmission could be never done for some abnormal scenarios, such as STP link timeout. This patch is to fix the issue. Check PHY status after starting process of enabling PHY for 50ms. If the PHY is still active, we disable it forcibly by PHY reset. Of course, we need to clear the PHY reset bit when enable PHY. Besides, the function disable_phy_v3_hw() should not be suitable to call in interrupts for hilink bug for this 50ms delay. Then, we do link reset for hilink bug directly. The change is that we don't clear the invalid dword count register. This is better. Because we should not clear such error count while not saved.
