* scsi: read host_busy via scsi_host_busy()Ming Lei2018-06-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | No functional change. Just introduce scsi_host_busy() and replace the direct read of scsi_host->host_busy with this new API.

* scsi: libsas: dynamically allocate and free ata hostJason Yan2018-06-192-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 2623c7a5f2 ("libata: add refcounting to ata_host") v4.17+ introduced refcounting to ata_host and will increase or decrease the refcount when adding or deleting transport ATA port. Now the ata host for libsas is embedded in domain_device, and the ->kref member is not initialized. Afer we add ata transport class, ata_host_get() will be called when adding transport ATA port and a warning will be triggered as below: refcount_t: increment on 0; use-after-free. WARNING: CPU: 2 PID: 103 at lib/refcount.c:153 refcount_inc+0x40/0x48 ...... Call trace: refcount_inc+0x40/0x48 ata_host_get+0x10/0x18 ata_tport_add+0x40/0x120 ata_sas_tport_add+0xc/0x14 sas_ata_init+0x7c/0xc8 sas_discover_domain+0x380/0x53c process_one_work+0x12c/0x288 worker_thread+0x58/0x3f0 kthread+0xfc/0x128 ret_from_fork+0x10/0x18 And also when removing transport ATA port ata_host_put() will be called and another similar warning will be triggered. If the refcount decreased to zero, the ata host will be freed. But this ata host is only part of domain_device, it cannot be freed directly. So we have to change this embedded static ata host to a dynamically allocated ata host and initialize the ->kref member. To use ata_host_get() and ata_host_put() in libsas, we need to move the declaration of these functions to the public libata.h and export them.

The difference is that iter_info struct may contain marks that should not be handled and are represented as NULL arguments to inode_mark or vfsmount_mark. Instead of passing the inode_mark and vfsmount_mark arguments, add a report_mask member to iter_info struct to indicate which marks should be handled, versus marks that should only be kept alive during user wait.

Instead of storing a type mask in connector->flags, store a single type id in connector->type to identify the type of object. When a connector object is detached from the object, its type is set to FSNOTIFY_OBJ_TYPE_DETACHED and this object is not going to be reused. The function fsnotify_clear_marks_by_group() is the only place where type mask was used, so use type flags instead of type id to this function. This change is going to be more convenient when adding a new object type (super block). Signed-off-by: Amir Goldstein <amir73il@gmail.com> Signed-off-by: Jan Kara <jack@suse.cz>

To this end: (1) Only one dynamic root superblock is now created per network namespace and this is shared between all attempts to mount it. This makes it easier to find the superblock to modify. (2) When a dynamic root superblock is created, the list of cells is walked and directories created for each cell already defined. (3) When a new cell is added, if a dynamic root superblock exists, a directory is created for it. (4) When a cell is destroyed, the directory is removed. (5) These directories are created by calling lookup_one_len() on the root dir which automatically creates them if they don't exist. [*] Inasmuch as network namespaces are currently supported here.

However it actually only needs very few code from skb_gro_receive(). Besides, NAPI_GRO_CB has to be set while most of its members are not needed here. This patch is to add sctp_packet_gso_append() to build GSO frames instead of skb_gro_receive(), and it would avoid many unnecessary checks and make the code clearer. Note that sctp will use page frags instead of frag_list to build GSO frames in another patch. But it may take time, as sctp's GSO frames may have different size. skb_segment() can only split it into the frags with the same size, which would break the border of sctp chunks.

Looks like the recent conversion from poll to poll_mask callback started in 152524231023 ("net: add support for ->poll_mask in proto_ops") missed to eventually convert kTLS, too: TCP's ->poll was converted over to the ->poll_mask in commit 2c7d3dacebd4 ("net/tcp: convert to ->poll_mask") and therefore kTLS wrongly saved the ->poll old one which is now NULL. Convert kTLS over to use ->poll_mask instead. Also instead of POLLIN | POLLRDNORM use the proper EPOLLIN | EPOLLRDNORM bits as the case in tcp_poll_mask() as well that is mangled here.

From Gao Feng. 14) Missing initialization of match/target in ebtables, from Florian Westphal. 15) Remove useless nft_dup.h file in include path, from C.

When add new bit IPS_OFFLOAD_BIT whose value is 14, we should increase the __IPS_MAX_BIT too, from 14 to 15. There is no any bug in current codes, although it lost one loop in __ctnetlink_change_status. Because the new bit IPS_OFFLOAD_BIT belongs the IPS_UNCHANGEABLE_MASK.

However when restoring the saved list, the zero timeout value means permanent elelements. The new behaviour is that timing out entries are listed with "timeout 1" instead of zero.
