Subject: sctp: use the right sk after waking up from wait_buf sleep
From: Xin Long <lucien.xin(a)gmail.com>
[ Upstream commit cea0cc80a6777beb6eb643d4ad53690e1ad1d4ff ]
Commit dfcb9f4f99f1 ("sctp: deny peeloff operation on asocs with threads
sleeping on it") fixed the race between peeloff and wait sndbuf by
checking waitqueue_active(&asoc->wait) in sctp_do_peeloff().
But it actually doesn't work, as even if waitqueue_active returns false
the waiting sndbuf thread may still not yet hold sk lock. After asoc is
peeled off, sk is not asoc->base.sk any more, then to hold the old sk
lock couldn't make assoc safe to access.
This patch is to fix this by changing to hold the new sk lock if sk is
not asoc->base.sk, meanwhile, also set the sk in sctp_sendmsg with the
new sk.
With this fix, there is no more race between peeloff and waitbuf, the
check 'waitqueue_active' in sctp_do_peeloff can be removed.
Thanks Marcelo and Neil for making this clear.
v1->v2:
fix it by changing to lock the new sock instead of adding a flag in asoc.

Subject: sctp: do not free asoc when it is already dead in sctp_sendmsg
From: Xin Long <lucien.xin(a)gmail.com>
[ Upstream commit ca3af4dd28cff4e7216e213ba3b671fbf9f84758 ]
Now in sctp_sendmsg sctp_wait_for_sndbuf could schedule out without
holding sock sk. It means the current asoc can be freed elsewhere,
like when receiving an abort packet.
If the asoc is just created in sctp_sendmsg and sctp_wait_for_sndbuf
returns err, the asoc will be freed again due to new_asoc is not nil.
An use-after-free issue would be triggered by this.
This patch is to fix it by setting new_asoc with nil if the asoc is
already dead when cpu schedules back, so that it will not be freed
again in sctp_sendmsg.
v1->v2:
set new_asoc as nil in sctp_sendmsg instead of sctp_wait_for_sndbuf.

From: Xin Long <lucien.xin(a)gmail.com>
[ Upstream commit e39d5246111399dbc6e11cd39fd8580191b86c47 ]
Now when creating fnhe for redirect, it sets fnhe_expires for this
new route cache. But when updating the exist one, it doesn't do it.
It will cause this fnhe never to be expired.
Paolo already noticed it before, in Jianlin's test case, it became
even worse:
When ip route flush cache, the old fnhe is not to be removed, but
only clean it's members. When redirect comes again, this fnhe will
be found and updated, but never be expired due to fnhe_expires not
being set.
So fix it by simply updating fnhe_expires even it's for redirect.

From: Xin Long <lucien.xin(a)gmail.com>
[ Upstream commit cebe84c6190d741045a322f5343f717139993c08 ]
Now when ip route flush cache and it turn out all fnhe_genid != genid.
If a redirect/pmtu icmp packet comes and the old fnhe is found and all
it's members but fnhe_genid will be updated.
Then next time when it looks up route and tries to rebind this fnhe to
the new dst, the fnhe will be flushed due to fnhe_genid != genid. It
causes this redirect/pmtu icmp packet acutally not to be applied.
This patch is to also reset fnhe_genid when updating a route cache.

Subject: lib/genalloc.c: make the avail variable an atomic_long_t
From: Stephen Bates <sbates(a)raithlin.com>
[ Upstream commit 36a3d1dd4e16bcd0d2ddfb4a2ec7092f0ae0d931 ]
If the amount of resources allocated to a gen_pool exceeds 2^32 then the
avail atomic overflows and this causes problems when clients try and
borrow resources from the pool. This is only expected to be an issue on
64 bit systems.
Add the <linux/atomic.h> header to pull in atomic_long* operations. So
that 32 bit systems continue to use atomic32_t but 64 bit systems can
use atomic64_t.

On successful rename, the "old_dentry" is retained and is attached to
the "new_dir", so we need to call nfs_set_verifier() accordingly.

Subject: libata: drop WARN from protocol error in ata_sff_qc_issue()
From: Tejun Heo <tj(a)kernel.org>
[ Upstream commit 0580b762a4d6b70817476b90042813f8573283fa ]
ata_sff_qc_issue() expects upper layers to never issue commands on a
command protocol that it doesn't implement. While the assumption
holds fine with the usual IO path, nothing filters based on the
command protocol in the passthrough path (which was added later),
allowing the warning to be tripped with a passthrough command with the
right (well, wrong) protocol.
Failing with AC_ERR_SYSTEM is the right thing to do anyway. Remove
the unnecessary WARN.

The syzkaller folks reported a nested_run_pending warning during userspace
clear VMX capability which is exposed to L1 before.
The warning gets thrown while doing
(*(uint32_t*)0x20aecfe8 = (uint32_t)0x1);
(*(uint32_t*)0x20aecfec = (uint32_t)0x0);
(*(uint32_t*)0x20aecff0 = (uint32_t)0x3a);
(*(uint32_t*)0x20aecff4 = (uint32_t)0x0);
(*(uint64_t*)0x20aecff8 = (uint64_t)0x0);
r[29] = syscall(__NR_ioctl, r[4], 0x4008ae89ul,
0x20aecfe8ul, 0, 0, 0, 0, 0, 0);
i.e. KVM_SET_MSR ioctl with
struct kvm_msrs {
.nmsrs = 1,
.pad = 0,
.entries = {
{.index = MSR_IA32_FEATURE_CONTROL,
.reserved = 0,
.data = 0}
}
}
The VMLANCH/VMRESUME emulation should be stopped since the CPU is going to
reset here. This patch resets the nested_run_pending since the CPU is going
to be reset hence there should be nothing pending.

This is because net->ipv6.mr6_tables is not initialized at that point,
ip6mr_rules_init() is not called yet, therefore on the error path when
we iterator the list, we trigger this oops. Fix this by reordering
ip6mr_rules_init() before icmpv6_sk_init().

As this variable is used as integer in other places, create a new variable
that allows to fix the following sparse issue (-Wtypesign):

[ Upstream commit 31fde034a8bd964a5c7c1a5663fc87a913158db2 ]
The UMR's QP is created by calling mlx5_ib_create_qp directly, and
therefore the send CQ and the recv CQ on the ibqp weren't assigned.
Assign them right after calling the mlx5_ib_create_qp to assure
that any access to those pointers will work as expected and won't
crash the system as might happen as part of reset flow.

Subject: IB/mlx4: Increase maximal message size under UD QP
From: Mark Bloch <markb(a)mellanox.com>
[ Upstream commit 5f22a1d87c5315a98981ecf93cd8de226cffe6ca ]
Maximal message should be used as a limit to the max message payload allowed,
without the headers. The ConnectX-3 check is done against this value includes
the headers. When the payload is 4K this will cause the NIC to drop packets.
Increase maximal message to 8K as workaround, this shouldn't change current
behaviour because we continue to set the MTU to 4k.
To reproduce;
set MTU to 4296 on the corresponding interface, for example:
ifconfig eth0 mtu 4296 (both server and client)
On server:
ib_send_bw -c UD -d mlx4_0 -s 4096 -n 1000000 -i1 -m 4096
On client:
ib_send_bw -d mlx4_0 -c UD <server_ip> -s 4096 -n 1000000 -i 1 -m 4096

While modifying the driver to use the STOP interrupt, the completion of the
intermediate transfers need to wake the driver back up in order to initiate
the next transfer (restart condition). Otherwise you get never ending
interrupts and only the first transfer sent.

From: Krzysztof Kozlowski <krzk(a)kernel.org>
[ Upstream commit 07de4bc88ce6a4d898cad9aa4c99c1df7e87702d ]
In a regular interrupt handler driver was finishing the crypt/decrypt
request by calling complete on crypto request. This is disallowed since
converting to skcipher in commit b286d8b1a690 ("crypto: skcipher - Add
skcipher walk interface") and causes a warning:
WARNING: CPU: 0 PID: 0 at crypto/skcipher.c:430 skcipher_walk_first+0x13c/0x14c
The interrupt is marked shared but in fact there are no other users
sharing it. Thus the simplest solution seems to be to just use a
threaded interrupt handler, after converting it to oneshot.

handling in axon_ram_probe() to avoid doing that.
Also del_gendisk() does not drop a reference to gendisk allocated by
alloc_disk(). That has to be done by put_disk(). Add that call where
needed.

Subject: audit: ensure that 'audit=1' actually enables audit for PID 1
From: Paul Moore <paul(a)paul-moore.com>
[ Upstream commit 173743dd99a49c956b124a74c8aacb0384739a4c ]
Prior to this patch we enabled audit in audit_init(), which is too
late for PID 1 as the standard initcalls are run after the PID 1 task
is forked. This means that we never allocate an audit_context (see
audit_alloc()) for PID 1 and therefore miss a lot of audit events
generated by PID 1.
This patch enables audit as early as possible to help ensure that when
PID 1 is forked it can allocate an audit_context if required.

atm_dev_register() can fail here and passed parameters to free irq
which is not initialised. Initialization of 'dev->irq' happened after
the 'goto out_free_irq'. So using 'irq' insted of 'dev->irq' in
free_irq().

Subject: arm: KVM: Survive unknown traps from guests
From: Mark Rutland <mark.rutland(a)arm.com>
[ Upstream commit f050fe7a9164945dd1c28be05bf00e8cfb082ccf ]
Currently we BUG() if we see a HSR.EC value we don't recognise. As
configurable disables/enables are added to the architecture (controlled
by RES1/RES0 bits respectively), with associated synchronous exceptions,
it may be possible for a guest to trigger exceptions with classes that
we don't recognise.
While we can't service these exceptions in a manner useful to the guest,
we can avoid bringing down the host. Per ARM DDI 0406C.c, all currently
unallocated HSR EC encodings are reserved, and per ARM DDI
0487A.k_iss10775, page G6-4395, EC values within the range 0x00 - 0x2c
are reserved for future use with synchronous exceptions, and EC values
within the range 0x2d - 0x3f may be used for either synchronous or
asynchronous exceptions.
The patch makes KVM handle any unknown EC by injecting an UNDEFINED
exception into the guest, with a corresponding (ratelimited) warning in
the host dmesg. We could later improve on this with with a new (opt-in)
exit to the host userspace.
