2019-05-29RDMA/efa: Remove unneeded admin commands abort flowGal Pressman2-74/+1

2019-05-29RDMA/efa: Use kvzalloc instead of kzalloc with fallbackGal Pressman1-25/+21
Use kvzalloc which attempts to allocate a physically continuous buffer and fallbacks to virtually continuous on failure instead of open coding it in the driver. The is_vmalloc_addr function is used to determine whether the buffer is physically continuous or not (which determines direct vs indirect MR registration mode).

Commit 25c13324d03d ("IB/mlx5: Add steering SW ICM device memory type") breaks i386 build by introducing three 64-bit divisions. As the divisor is MLX5_SW_ICM_BLOCK_SIZE() which is always a power of 2, we can replace the division with bit operations.

2019-05-29IB/rdmavt: Fix alloc_qpn() WARN_ON()Mike Marciniszyn1-1/+2
The qpn allocation logic has a WARN_ON() that intends to detect the use of an index that will introduce bits in the lower order bits of the QOS bits in the QPN. Unfortunately, it has the following bugs: - it misfires when wrapping QPN allocation for non-QOS - it doesn't correctly detect low order QOS bits (despite the comment) The WARN_ON() should not be applied to non-QOS (qos_shift == 1). Additionally, it SHOULD test the qpn bits per the table below: 2 data VLs: [qp7, qp6, qp5, qp4, qp3, qp2, qp1] ^ [ 0, 0, 0, 0, 0, 0, sc0], qp bit 1 always 0* 3-4 data VLs: [qp7, qp6, qp5, qp4, qp3, qp2, qp1] ^ [ 0, 0, 0, 0, 0, sc1, sc0], qp bits [21] always 0 5-8 data VLs: [qp7, qp6, qp5, qp4, qp3, qp2, qp1] ^ [ 0, 0, 0, 0, sc2, sc1, sc0] qp bits [321] always 0 Fix by qualifying the warning for qos_shift > 1 and producing the correct mask to insure the above bits are zero without generating a superfluous warning.

2019-05-28RDMA: Convert put_page() to put_user_page*()John Hubbard7-31/+27
For infiniband code that retains pages via get_user_pages*(), release those pages via the new put_user_page(), or put_user_pages*(), instead of put_page() This is a tiny part of the second step of fixing the problem described in [1]. The steps are: 1) Provide put_user_page*() routines, intended to be used for releasing pages that were pinned via get_user_pages*(). 2) Convert all of the call sites for get_user_pages*(), to invoke put_user_page*(), instead of put_page(). This involves dozens of call sites, and will take some time. 3) After (2) is complete, use get_user_pages*() and put_user_page*() to implement tracking of these pages. This tracking will be separate from the existing struct page refcounting. 4) Use the tracking and identification of these pages, to implement special handling (especially in writeback paths) when the pages are backed by a filesystem. Again, [1] provides details as to why that is desirable.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull SPDX update from Greg KH: "Here is a series of patches that add SPDX tags to different kernel files, based on two different things: - SPDX entries are added to a bunch of files that we missed a year ago that do not have any license information at all. These were either missed because the tool saw the MODULE_LICENSE() tag, or some EXPORT_SYMBOL tags, and got confused and thought the file had a real license, or the files have been added since the last big sweep, or they were Makefile/Kconfig files, which we didn't touch last time. - Add GPL-2.0-only or GPL-2.0-or-later tags to files where our scan tools can determine the license text in the file itself. Where this happens, the license text is removed, in order to cut down on the 700+ different ways we have in the kernel today, in a quest to get rid of all of these. These patches have been out for review on the linux-spdx@vger mailing list, and while they were created by automatic tools, they were hand-verified by a bunch of different people, all whom names are on the patches are reviewers. The reason for these "large" patches is if we were to continue to progress at the current rate of change in the kernel, adding license tags to individual files in different subsystems, we would be finished in about 10 years at the earliest. There will be more series of these types of patches coming over the next few weeks as the tools and reviewers crunch through the more "odd" variants of how to say "GPLv2" that developers have come up with over the years, combined with other fun oddities (GPL + a BSD disclaimer?) that are being unearthed, with the goal for the whole kernel to be cleaned up.

2019-05-21RDMA/srp: Rename SRP sysfs name after IB device rename triggerLeon Romanovsky2-10/+43
SRP logic used device name and port index as symlink to relevant kobject. If the IB device is renamed then the prior name will be re-used by the next device plugged in and sysfs will panic as SRP will try to re-use the same name. mlx5_ib: Mellanox Connect-IB Infiniband driver v5.0-0 sysfs: cannot create duplicate filename '/class/infiniband_srp/srp-mlx5_0-1' CPU: 3 PID: 1107 Comm: modprobe Not tainted 5.1.0-for-upstream-perf-2019-05-12_15-09-52-87 #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.10.2-1ubuntu1 04/01/2014 Call Trace: dump_stack+0x5a/0x73 sysfs_warn_dup+0x58/0x70 sysfs_do_create_link_sd.isra.2+0xa3/0xb0 device_add+0x33f/0x660 srp_add_one+0x301/0x4f0 [ib_srp] add_client_context+0x99/0xe0 [ib_core] enable_device_and_get+0xd1/0x1b0 [ib_core] ib_register_device+0x533/0x710 [ib_core] ? mutex_lock+0xe/0x30 __mlx5_ib_add+0x23/0x70 [mlx5_ib] mlx5_add_device+0x4e/0xd0 [mlx5_core] mlx5_register_interface+0x85/0xc0 [mlx5_core] ? 0xffffffffa0791000 do_one_initcall+0x4b/0x1cb ? kmem_cache_alloc_trace+0xc6/0x1d0 ? do_init_module+0x22/0x21f do_init_module+0x5a/0x21f load_module+0x17f2/0x1ca0 ? m_show+0x1c0/0x1c0 __do_sys_finit_module+0x94/0xe0 do_syscall_64+0x48/0x120 entry_SYSCALL_64_after_hwframe+0x44/0xa9 RIP: 0033:0x7f157cce10d9 The module load/unload sequence was used to trigger such kernel panic: sudo modprobe ib_srp sudo modprobe -r mlx5_ib sudo modprobe -r mlx5_core sudo modprobe mlx5_core Have SRP track the name of the core device so that it can't have a name collision.

2019-05-17net/mlx5: E-Switch, Correct type to u16 for vport_num and int for vport_indexParav Pandit2-12/+13
To avoid any ambiguity between vport index and vport number, rename functions that had vport, to vport_num or vport_index appropriately. vport_num is u16 hence change mlx5_eswitch_index_to_vport_num() return type to u16. vport_index is an int in vport array. Hence change input type of vport index in mlx5_eswitch_index_to_vport_num() to int. Correct multiple eswitch representor interfaces use type u16 of rep->vport as type int vport_index. Send vport FW commands with correct eswitch u16 vport_num instead host int vport_index.
