#1565670 — [PATCH 4.9 038/130] fuse: clear FR_PENDING flag when moving requests out of pending queue

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tahsin Erdogan <tahsin@google.com>

commit a8a86d78d673b1c99fe9b0064739fde9e9774184 upstream.

fuse_abort_conn() moves requests from pending list to a temporary list
before canceling them. This operation races with request_wait_answer()
which also tries to remove the request after it gets a fatal signal. It
checks FR_PENDING flag to determine whether the request is still in the
pending list.

Make fuse_abort_conn() clear FR_PENDING flag so that request_wait_answer()
does not remove the request from temporary list.

This bug causes an Oops when trying to delete an already deleted list entry
in end_requests().

#1565671 — [PATCH 4.9 051/130] KVM: arm/arm64: vgic: Fix deadlock on error handling

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Marc Zyngier <marc.zyngier@arm.com>

commit 1193e6aeecb36c74c48c7cd0f641acbbed9ddeef upstream.

Dmitry Vyukov reported that the syzkaller fuzzer triggered a
deadlock in the vgic setup code when an error was detected, as
the cleanup code tries to take a lock that is already held by
the setup code.

The fix is to avoid retaking the lock when cleaning up, by
telling the cleanup function that we already hold it.

#1565672 — [PATCH 4.9 003/130] IB/rxe: avoid putting a large struct rxe_qp on stack

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@arndb.de>

commit a0fa72683e78979ef1123d679b1c40ae28bd9096 upstream.

A race condition fix added an rxe_qp structure to the stack in order
to be able to perform rollback in rxe_requester(), but the structure
is large enough to trigger the warning for possible stack overflow:

drivers/infiniband/sw/rxe/rxe_req.c: In function 'rxe_requester':
drivers/infiniband/sw/rxe/rxe_req.c:757:1: error: the frame size of 2064 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]

This changes the rollback function to only save the psn inside
the qp, which is the only field we access in the rollback_qp
anyway.

CONFIG_ARC_DW2_UNWIND, but used it unconditionally which broke builds
when the option was disabled. Fix that by adjusting the #ifdef guard.

And while at it add a missing guard (for unwinder) in module.c as well

#1565676 — [PATCH 4.9 035/130] svcrpc: dont leak contexts on PROC_DESTROY

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: J. Bruce Fields <bfields@redhat.com>

commit 78794d1890708cf94e3961261e52dcec2cc34722 upstream.

Context expiry times are in units of seconds since boot, not unix time.

The use of get_seconds() here therefore sets the expiry time decades in
the future.  This prevents timely freeing of contexts destroyed by
client RPC_GSS_PROC_DESTROY requests.  We'd still free them eventually
(when the module is unloaded or the container shut down), but a lot of
contexts could pile up before then.

#1565693 — [PATCH 4.9 021/130] perf jit: Enable jitdump support without dwarf

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Maciej Debski <maciejd@google.com>

commit 621cb4e7837e39d25a5af5a785ad282cdd2b4ce8 upstream.

This patch modifies the build dependencies on the jitdump support in
perf. As it stands jitdump was wrongfully made dependent 100% on using
DWARF. However, the dwarf dependency, only exist if generating the
source line table in genelf_debug.c. The rest of the support does not
need DWARF.

This patch removes the dependency on DWARF for the entire jitdump
support. It keeps it only for the genelf_debug.c support.

#1565697 — [PATCH 4.9 014/130] IB/IPoIB: Remove cant use GFP_NOIO warning

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Kamal Heib <kamalh@mellanox.com>

commit 0b59970e7d96edcb3c7f651d9d48e1a59af3c3b0 upstream.

Remove the warning print of "can't use of GFP_NOIO" to avoid prints in
each QP creation when devices aren't supporting IB_QP_CREATE_USE_GFP_NOIO.

This print become more annoying when the IPoIB interface is configured
to work in connected mode.

#1565699 — [PATCH 4.9 012/130] IB/mlx4: When no DMFS for IPoIB, dont allow NET_IF QPs

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Eran Ben Elisha <eranbe@mellanox.com>

commit 1f22e454df2eb99ba6b7ace3f594f6805cdf5cbc upstream.

According to the firmware spec, FLOW_STEERING_IB_UC_QP_RANGE command is
supported only if dmfs_ipoib bit is set.

If it isn't set we want to ensure allocating NET_IF QPs fail. We do so
by filling out the allocation bitmap. By thus, the NET_IF QPs allocating
function won't find any free QP and will fail.
