[PATCH stable v4.17] PCI: aardvark: Size bridges before resources allocation

by Thomas Petazzoni

From: Zachary Zhang <zhangzg(a)marvell.com> commit 91a2968e245d6ba616db37001fa1a043078b1a65 usptream. The PCIE I/O and MEM resource allocation mechanism is that root bus goes through the following steps: 1. Check PCI bridges' range and computes I/O and Mem base/limits. 2. Sort all subordinate devices I/O and MEM resource requirements and allocate the resources and writes/updates subordinate devices' requirements to PCI bridges I/O and Mem MEM/limits registers. Currently, PCI Aardvark driver only handles the second step and lacks the first step, so there is an I/O and MEM resource allocation failure when using a PCI switch. This commit fixes that by sizing bridges before doing the resource allocation.

patch "tools: hv: fcopy: set 'error' in case an unknown operation was" added to char-misc-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled tools: hv: fcopy: set 'error' in case an unknown operation was to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From c2d68afba86d1ff01e7300c68bc16a9234dcd8e9 Mon Sep 17 00:00:00 2001 From: Vitaly Kuznetsov <vkuznets(a)redhat.com> Date: Mon, 17 Sep 2018 04:14:55 +0000 Subject: tools: hv: fcopy: set 'error' in case an unknown operation was requested 'error' variable is left uninitialized in case we see an unknown operation.

Please apply 2c155709e4ef ("staging: android: ion: fix ION_IOC_{MAP,SHARE} use-after-free") to 3.18.y

by Greg Hackmann

2c155709e4ef ("staging: android: ion: fix ION_IOC_{MAP,SHARE} use-after-free") was applied to 4.4.y a couple of weeks ago, and is needed on 3.18.y too. The patch cherry-picks and builds as-is on top of 3.18.123.

[PATCH v4.4.y] ext4: never move the system.data xattr out of the inode body

by Zubin Mithra

From: Theodore Ts'o <tytso(a)mit.edu> commit 8cdb5240ec5928b20490a2bb34cb87e9a5f40226 upstream. When expanding the extra isize space, we must never move the system.data xattr out of the inode body. For performance reasons, it doesn't make any sense, and the inline data implementation assumes that system.data xattr is never in the external xattr block. This addresses CVE-2018-10880 https://bugzilla.kernel.org/show_bug.cgi?id=200005 Backport Note: - dfa2064b22("ext4: factor out loop for freeing inode xattr space") factored out the loop from inside ext4_expand_extra_isize_ea to a separate function named ext4_xattr_make_inode_space. As the above commit is not present in 4.4.y, make the change inside ext4_expand_extra_isize_ea.

If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From b4a4957d3d1c328b733fce783b7264996f866ad2 Mon Sep 17 00:00:00 2001 From: "Michael J. Ruhl" <michael.j.ruhl(a)intel.com> Date: Thu, 20 Sep 2018 12:59:14 -0700 Subject: [PATCH] IB/hfi1: Fix destroy_qp hang after a link down rvt_destroy_qp() cannot complete until all in process packets have been released from the underlying hardware. If a link down event occurs, an application can hang with a kernel stack similar to: cat /proc/<app PID>/stack quiesce_qp+0x178/0x250 [hfi1] rvt_reset_qp+0x23d/0x400 [rdmavt] rvt_destroy_qp+0x69/0x210 [rdmavt] ib_destroy_qp+0xba/0x1c0 [ib_core] nvme_rdma_destroy_queue_ib+0x46/0x80 [nvme_rdma] nvme_rdma_free_queue+0x3c/0xd0 [nvme_rdma] nvme_rdma_destroy_io_queues+0x88/0xd0 [nvme_rdma] nvme_rdma_error_recovery_work+0x52/0xf0 [nvme_rdma] process_one_work+0x17a/0x440 worker_thread+0x126/0x3c0 kthread+0xcf/0xe0 ret_from_fork+0x58/0x90 0xffffffffffffffff quiesce_qp() waits until all outstanding packets have been freed. This wait should be momentary. During a link down event, the cleanup handling does not ensure that all packets caught by the link down are flushed properly. This is caused by the fact that the freeze path and the link down event is handled the same. This is not correct. The freeze path waits until the HFI is unfrozen and then restarts PIO. A link down is not a freeze event. The link down path cannot restart the PIO until link is restored. If the PIO path is restarted before the link comes up, the application (QP) using the PIO path will hang (until link is restored). Fix by separating the linkdown path from the freeze path and use the link down path for link down events. Close a race condition sc_disable() by acquiring both the progress and release locks. Close a race condition in sc_stop() by moving the setting of the flag bits under the alloc lock.
