The newly added suspend/resume support causes harmless warnings when CONFIG_PM is disabled: smartpqi/smartpqi_init.c:5147:12: error: 'pqi_ctrl_wait_for_pending_io' defined but not used [-Werror=unused-function] smartpqi/smartpqi_init.c:2019:13: error: 'pqi_wait_until_lun_reset_finished' defined but not used [-Werror=unused-function] smartpqi/smartpqi_init.c:2013:13: error: 'pqi_wait_until_scan_finished' defined but not used [-Werror=unused-function] We can avoid the warnings by removing the #ifdef around the handlers and instead marking them as __maybe_unused, which will let gcc drop the unused code silently. Fixes: f44d210312a6 ("scsi: smartpqi: add suspend and resume support") Signed-off-by:Arnd Bergmann <arnd@arndb.de> Signed-off-by:

When copying attributes, the len argument was padded out and the resulting memcpy() would copy beyond the end of the source buffer. Avoid this, and use size_t for val_len to avoid all the casts. Similarly, avoid source buffer casts and use void *. Additionally enforces val_len can be represented by u16 and that the DMA buffer was not overflowed. Fixes the size of mfa, which is not FC_FDMI_PORT_ATTR_MAXFRAMESIZE_LEN (but it will be padded up to 4). This was noticed by the future CONFIG_FORTIFY_SOURCE checks.

iscsiadm session login can fail with the following error: iscsiadm: Could not login to [iface: default, target: iqn.1986-03.com... iscsiadm: initiator reported error (9 - internal error) When /etc/iscsi/iscsid.conf sets node.session.cmds_max = 4096, it results in 64K-sized kmallocs per session. A system under fragmented slab pressure may not have any 64K objects available and fail iscsiadm session login. Even though memory objects of a smaller size are available, the large order allocation ends up failing. The kernel prints a warning and does dump_stack, like below: iscsid: page allocation failure: order:4, mode:0xc0d0 CPU: 0 PID: 2456 Comm: iscsid Not tainted 4.1.12-61.1.28.el6uek.x86_64 #2 Call Trace: [<ffffffff816c6e40>] dump_stack+0x63/0x83 [<ffffffff8118e58a>] warn_alloc_failed+0xea/0x140 [<ffffffff81191df9>] __alloc_pages_slowpath+0x409/0x760 [<ffffffff81192401>] __alloc_pages_nodemask+0x2b1/0x2d0 [<ffffffffa048f6c0>] ? dev_attr_host_ipaddress+0x20/0xffffffffffffc722 [<ffffffff811dc38f>] alloc_pages_current+0xaf/0x170 [<ffffffff81192581>] alloc_kmem_pages+0x31/0xd0 [<ffffffffa048f600>] ? iscsi_transport_group+0x20/0xffffffffffffc7e2 [<ffffffff811ad738>] kmalloc_order+0x18/0x50 [<ffffffff811ad7a4>] kmalloc_order_trace+0x34/0xe0 [<ffffffff8146ee30>] ? transport_remove_classdev+0x70/0x70 [<ffffffff811e843d>] __kmalloc+0x27d/0x2a0 [<ffffffff810c8cbd>] ? complete_all+0x4d/0x60 [<ffffffffa04af299>] iscsi_pool_init+0x69/0x160 [libiscsi] [<ffffffff81465d90>] ? device_initialize+0xb0/0xd0 [<ffffffffa04af510>] iscsi_session_setup+0x180/0x2f4 [libiscsi] [<ffffffffa04c5a60>] ? iscsi_max_lun+0x20/0xfffffffffffffa9e [iscsi_tcp] [<ffffffffa04c531f>] iscsi_sw_tcp_session_create+0xcf/0x150 [iscsi_tcp] [<ffffffffa04c5a60>] ? iscsi_max_lun+0x20/0xfffffffffffffa9e [iscsi_tcp] [<ffffffffa048a633>] iscsi_if_create_session+0x33/0xd0 [<ffffffffa04c5a60>] ? iscsi_max_lun+0x20/0xfffffffffffffa9e [iscsi_tcp] [<ffffffffa048abd8>] iscsi_if_recv_msg+0x508/0x8c0 [scsi_transport_iscsi] [<ffffffff811922eb>] ? __alloc_pages_nodemask+0x19b/0x2d0 [<ffffffff811e6d69>] ? __kmalloc_node_track_caller+0x209/0x2c0 [<ffffffffa048b00c>] iscsi_if_rx+0x7c/0x200 [scsi_transport_iscsi] [<ffffffff81623dc6>] netlink_unicast+0x126/0x1c0 [<ffffffff8162468c>] netlink_sendmsg+0x36c/0x400 [<ffffffff815d2fed>] sock_sendmsg+0x4d/0x60 [<ffffffff815d596a>] ___sys_sendmsg+0x30a/0x330 [<ffffffff811bc72c>] ? handle_pte_fault+0x20c/0x230 [<ffffffff811bc90c>] ? __handle_mm_fault+0x1bc/0x330 [<ffffffff811bcb32>] ? handle_mm_fault+0xb2/0x1a0 [<ffffffff815d5b99>] __sys_sendmsg+0x49/0x90 [<ffffffff815d5bf9>] SyS_sendmsg+0x19/0x20 [<ffffffff816cbb2e>] system_call_fastpath+0x12/0x71 Use kvzalloc for iscsi_pool in iscsi_pool_init.
