2017-07-01scsi: Add STARGET_CREATED_REMOVE state to scsi_target_stateEwan D. Milne1-0/+1
The addition of the STARGET_REMOVE state had the side effect of introducing a race condition that can cause a crash. scsi_target_reap_ref_release() checks the starget->state to see if it still in STARGET_CREATED, and if so, skips calling transport_remove_device() and device_del(), because the starget->state is only set to STARGET_RUNNING after scsi_target_add() has called device_add() and transport_add_device(). However, if an rport loss occurs while a target is being scanned, it can happen that scsi_remove_target() will be called while the starget is still in the STARGET_CREATED state. In this case, the starget->state will be set to STARGET_REMOVE, and as a result, scsi_target_reap_ref_release() will take the wrong path. The end result is a panic: [ 1255.356653] Oops: 0000 [#1] SMP [ 1255.360154] Modules linked in: x86_pkg_temp_thermal kvm_intel kvm irqbypass crc32c_intel ghash_clmulni_i [ 1255.393234] CPU: 5 PID: 149 Comm: kworker/u96:4 Tainted: G W 4.11.0+ #8 [ 1255.401879] Hardware name: Dell Inc.

2017-06-27scsi: sas: scsi_queue_work can fail, so make callers awareJohannes Thumshirn1-3/+3
libsas uses scsi_queue_work() to queue its internal event notifications. scsi_queue_work() can return -EINVAL if the work queue doesn't exist and it does call queue_work() which can return false if the work is already queued. Make the SAS event code capable of returning errors up to the caller, which is handy when changing to dynamically allocated work in libsas as well, as discussed here: https://lkml.org/lkml/2017/6/14/121.

Instead of explicitly calling scsi_req_init() after blk_get_request(), call that function from inside blk_get_request(). Add an .initialize_rq_fn() callback function to the block drivers that need it. Merge the IDE .init_rq_fn() function into .initialize_rq_fn() because it is too small to keep it as a separate function. Keep the scsi_req_init() call in ide_prep_sense() because it follows a blk_rq_init() call.

2017-06-12scsi: Protect SCSI device state changes with a mutexBart Van Assche1-0/+1
Serializing SCSI device state changes avoids that two state changes can occur concurrently, e.g. the state changes in scsi_target_block() and __scsi_remove_device(). This serialization is essential to make patch "Make __scsi_remove_device go straight from BLOCKED to DEL" work reliably. Enable this mechanism for all scsi_target_*block() callers but not for the scsi_internal_device_unblock() calls from the mpt3sas driver because that driver can call scsi_internal_device_unblock() from atomic context.

2017-06-12scsi: Avoid that scsi_exit_rq() triggers a use-after-freeBart Van Assche1-0/+1
Dereferencing shost from scsi_exit_rq() is not safe because the SCSI host may already have been freed when scsi_exit_rq() is called. Increasing the shost reference count in scsi_init_rq() and dropping that reference in scsi_exit_rq() is nontrivial since scsi_host_dev_release() may sleep and since scsi_exit_rq() may be called from interrupt context. Since scsi_exit_rq() only needs a single bit from shost, copy that bit into struct scsi_cmnd.

2017-06-09block: introduce new block status code typeChristoph Hellwig1-1/+1
Currently we use nornal Linux errno values in the block layer, and while we accept any error a few have overloaded magic meanings. This patch instead introduces a new blk_status_t value that holds block layer specific status codes and explicitly explains their meaning. Helpers to convert from and to the previous special meanings are provided for now, but I suspect we want to get rid of them in the long run - those drivers that have a errno input (e.g. networking) usually get errnos that don't know about the special block layer overloads, and similarly returning them to userspace will usually return somethings that strictly speaking isn't correct for file system operations, but that's left as an exercise for later. For now the set of errors is a very limited set that closely corresponds to the previous overloaded errno values, but there is some low hanging fruite to improve it. blk_status_t (ab)uses the sparse __bitwise annotations to allow for sparse typechecking, so that we can easily catch places passing the wrong values.

2017-05-11uapi: export all headers under uapi directoriesNicolas Dichtel1-0/+0
Regularly, when a new header is created in include/uapi/, the developer forgets to add it in the corresponding Kbuild file. This error is usually detected after the release is out. In fact, all headers under uapi directories should be exported, thus it's useless to have an exhaustive list. After this patch, the following files, which were not exported, are now exported (with make headers_install_all): asm-arc/kvm_para.h asm-arc/ucontext.h asm-blackfin/shmparam.h asm-blackfin/ucontext.h asm-c6x/shmparam.h asm-c6x/ucontext.h asm-cris/kvm_para.h asm-h8300/shmparam.h asm-h8300/ucontext.h asm-hexagon/shmparam.h asm-m32r/kvm_para.h asm-m68k/kvm_para.h asm-m68k/shmparam.h asm-metag/kvm_para.h asm-metag/shmparam.h asm-metag/ucontext.h asm-mips/hwcap.h asm-mips/reg.h asm-mips/ucontext.h asm-nios2/kvm_para.h asm-nios2/ucontext.h asm-openrisc/shmparam.h asm-parisc/kvm_para.h asm-powerpc/perf_regs.h asm-sh/kvm_para.h asm-sh/ucontext.h asm-tile/shmparam.h asm-unicore32/shmparam.h asm-unicore32/ucontext.h asm-x86/hwcap2.h asm-xtensa/kvm_para.h drm/armada_drm.h drm/etnaviv_drm.h drm/vgem_drm.h linux/aspeed-lpc-ctrl.h linux/auto_dev-ioctl.h linux/bcache.h linux/btrfs_tree.h linux/can/vxcan.h linux/cifs/cifs_mount.h linux/coresight-stm.h linux/cryptouser.h linux/fsmap.h linux/genwqe/genwqe_card.h linux/hash_info.h linux/kcm.h linux/kcov.h linux/kfd_ioctl.h linux/lightnvm.h linux/module.h linux/nbd-netlink.h linux/nilfs2_api.h linux/nilfs2_ondisk.h linux/nsfs.h linux/pr.h linux/qrtr.h linux/rpmsg.h linux/sched/types.h linux/sed-opal.h linux/smc.h linux/smc_diag.h linux/stm.h linux/switchtec_ioctl.h linux/vfio_ccw.h linux/wil6210_uapi.h rdma/bnxt_re-abi.h Note that I have removed from this list the files which are generated in every exported directories (like .install or .install.cmd).

This patch allows scsi drivers that expose virturalized fibre channel devices but that do not expose rports to successfully rescan the scsi bus via echo "- - -" > /sys/class/scsi_host/hostX/scan. Drivers can create a pseudo rport and indicate FC_PORT_ROLE_FCP_DUMMY_INITIATOR as the rport's role in fc_rport_identifiers.

2017-03-01scsi: mpt3sas: Avoid sleeping in interrupt contextBart Van Assche1-0/+4
Commit 669f044170d8 ("scsi: srp_transport: Move queuecommand() wait code to SCSI core") can make scsi_internal_device_block() sleep. However, the mpt3sas driver can call this function from an interrupt handler. Hence add a second argument to scsi_internal_device_block() that restores the old behavior of this function for the mpt3sas handler. The call chain that triggered an "IRQ handler enabled interrupts" complaint is as follows: _base_interrupt() -> _base_async_event() -> mpt3sas_scsih_event_callback() -> _scsih_check_topo_delete_events() -> _scsih_block_io_to_children_attached_directly() -> _scsih_block_io_device() -> _scsih_internal_device_block() -> scsi_internal_device_block() Reported-by: Omar Sandoval <osandov@osandov.com> Signed-off-by: Bart Van Assche <bart.vanassche@sandisk.com> Cc: Omar Sandoval <osandov@osandov.com> Cc: Hannes Reinecke <hare@suse.com> Cc: Sagi Grimberg <sagi@grimberg.me> Cc: Christoph Hellwig <hch@lst.de> Cc: Sathya Prakash <sathya.prakash@broadcom.com> Cc: Chaitra P B <chaitra.basappa@broadcom.com> Cc: Suganath Prabu Subramani <suganath-prabu.subramani@broadcom.com> Cc: Sreekanth Reddy <Sreekanth.Reddy@broadcom.com> Cc: <stable@vger.kernel.org> # v4.10+ Tested-by: Omar Sandoval <osandov@fb.com> Signed-off-by: Martin K.

2017-02-28scsi: libiscsi: add lock around task lists to fix list corruption regressionChris Leech1-0/+1
There's a rather long standing regression from the commit "libiscsi: Reduce locking contention in fast path" Depending on iSCSI target behavior, it's possible to hit the case in iscsi_complete_task where the task is still on a pending list (!list_empty(&task->running)). When that happens the task is removed from the list while holding the session back_lock, but other task list modification occur under the frwd_lock. That leads to linked list corruption and eventually a panicked system. Rather than back out the session lock split entirely, in order to try and keep some of the performance gains this patch adds another lock to maintain the task lists integrity. Major enterprise supported kernels have been backing out the lock split for while now, thanks to the efforts at IBM where a lab setup has the most reliable reproducer I've seen on this issue. This patch has been tested there successfully.
