[ Upstream commit cc29a1b0a3 ]
scsi_mq_setup_tags(), which is called by scsi_add_host(), calculates the
command size to allocate based on the prot_capabilities. In the isci
driver, scsi_host_set_prot() is called after scsi_add_host() so the command
size gets calculated to be smaller than it needs to be. Eventually,
scsi_mq_init_request() locates the 'prot_sdb' after the command assuming it
was sized correctly and a buffer overrun may occur.
However, seeing blk_mq_alloc_rqs() rounds up to the nearest cache line
size, the mistake can go unnoticed.
The bug was noticed after the struct request size was reduced by commit
9d037ad707 ("block: remove req->timeout_list")
Which likely reduced the allocated space for the request by an entire cache
line, enough that the overflow could be hit and it caused a panic, on boot,
at:
RIP: 0010:t10_pi_complete+0x77/0x1c0
Call Trace:
<IRQ>
sd_done+0xf5/0x340

__do_softirq+0xa1/0x2e6
irq_exit+0xbc/0xd0
call_function_single_interrupt+0xf/0x20
</IRQ>
sd_done() would call scsi_prot_sg_count() which reads the number of
entities in 'prot_sdb', but seeing 'prot_sdb' is located after the end of
the allocated space it reads a garbage number and erroneously calls
t10_pi_complete().
To prevent this, the calls to scsi_host_set_prot() are moved into
isci_host_alloc() before the call to scsi_add_host(). Out of caution, also
move the similar call to scsi_host_set_guard().

[ Upstream commit b91d903688 ]
There is no code that decreases the reference count of stateful objects
in error path of the nft_add_set_elem(). this causes a leak of reference
count of stateful objects.
Test commands:
$nft add table ip filter
$nft add counter ip filter c1
$nft add map ip filter m1 { type ipv4_addr : counter \;}
$nft add element ip filter m1 { 1 : c1 }
$nft add element ip filter m1 { 1 : c1 }
$nft delete element ip filter m1 { 1 }
$nft delete counter ip filter c1
Result:
Error: Could not process rule: Device or resource busy
delete counter ip filter c1
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
At the second 'nft add element ip filter m1 { 1 : c1 }', the reference
count of the 'c1' is increased then it tries to insert into the 'm1'. but
the 'm1' already has same element so it returns -EEXIST.
But it doesn't decrease the reference count of the 'c1' in the error path.
Due to a leak of the reference count of the 'c1', the 'c1' can't be
removed by 'nft delete counter ip filter c1'.

commit 050c17f239 upstream.
The system call, get_mempolicy() [1], passes an unsigned long *nodemask
pointer and an unsigned long maxnode argument which specifies the length
of the user's nodemask array in bits (which is rounded up). The manual
page says that if the maxnode value is too small, get_mempolicy will
return EINVAL but there is no system call to return this minimum value.
To determine this value, some programs search /proc/<pid>/status for a
line starting with "Mems_allowed:" and use the number of digits in the
mask to determine the minimum value. A recent change to the way this line
is formatted [2] causes these programs to compute a value less than
MAX_NUMNODES so get_mempolicy() returns EINVAL.
Change get_mempolicy(), the older compat version of get_mempolicy(), and
the copy_nodes_to_user() function to use nr_node_ids instead of
MAX_NUMNODES, thus preserving the defacto method of computing the minimum
size for the nodemask array and the maxnode argument.

commit 83e37e0bdd upstream.
The starting of AP interface can fail due to invalid
beacon interval, which does not match the minimum gcd
requirement set by the wifi driver. In such case, the
beacon interval of that interface gets updated with
that invalid beacon interval.
The next time that interface is brought up in AP mode,
an interface combination check is performed and the
beacon interval is taken from the previously set value.
In a case where an invalid beacon interval, i.e. a beacon
interval value which does not satisfy the minimum gcd criteria
set by the driver, is set, all the subsequent trials to
bring that interface in AP mode will fail, even if the
subsequent trials have a valid beacon interval.
To avoid this, in case of a failure in bringing up an
interface in AP mode due to interface combination error,
the interface beacon interval which is stored in bss
conf, needs to be restored with the last working value
of beacon interval.

The function prototype used to call JITed eBPF code (ie. the type of the
struct bpf_prog bpf_func field) returns an unsigned int. The MIPS n64
ABI that MIPS64 kernels target defines that 32 bit integers should
always be sign extended when passed in registers as either arguments or
return values.
This means that when returning any value which may not already be sign
extended (ie. of type REG_64BIT or REG_32BIT_ZERO_EX) we need to perform
that sign extension in order to comply with the n64 ABI. Without this we
see strange looking test failures from test_bpf.ko, such as:
test_bpf: #65 ALU64_MOV_X:
dst = 4294967295 jited:1 ret -1 != -1 FAIL (1 times)
Although the return value printed matches the expected value, this is
only because printf is only examining the least significant 32 bits of
the 64 bit register value we returned. The register holding the expected
value is sign extended whilst the v0 register was set to a zero extended
value by our JITed code, so when compared by a conditional branch
instruction the values are not equal.
We already handle this when the return value register is of type
REG_32BIT_ZERO_EX, so simply extend this to also cover REG_64BIT.

commit 9e7382153f upstream.
The following commit
441dae8f2f ("tracing: Add support for display of tgid in trace output")
removed the call to print_event_info() from print_func_help_header_irq()
which results in the ftrace header not reporting the number of entries
written in the buffer. As this wasn't the original intent of the patch,
re-introduce the call to print_event_info() to restore the orginal
behaviour.

commit e7afe6c1d4 upstream.
While trying to reproduce a reported kernel panic on arm64, I discovered
that AUTH_GSS basically doesn't work at all with older enctypes on arm64
systems with CONFIG_VMAP_STACK enabled. It turns out there still a few
places using stack memory with scatterlists, causing krb5_encrypt() and
krb5_decrypt() to produce incorrect results (or a BUG if CONFIG_DEBUG_SG
is enabled).
Tested with cthon on v4.0/v4.1/v4.2 with krb5/krb5i/krb5p using
des3-cbc-sha1 and arcfour-hmac-md5.

[ Upstream commit 04c03114be ]
soukjin bae reported a crash in tcp_v4_err() handling
ICMP_DEST_UNREACH after tcp_write_queue_head(sk)
returned a NULL pointer.
Current logic should have prevented this :
if (seq != tp->snd_una || !icsk->icsk_retransmits ||
!icsk->icsk_backoff || fastopen)
break;
Problem is the write queue might have been purged
and icsk_backoff has not been cleared.

[ Upstream commit 3bed3cc415 ]
This patch addresses the fact that there are drivers, specifically tun,
that will call into the network page fragment allocators with buffer sizes
that are not cache aligned. Doing this could result in data alignment
and DMA performance issues as these fragment pools are also shared with the
skb allocator and any other devices that will use napi_alloc_frags or
netdev_alloc_frags.
Fixes: ffde7328a3 ("net: Split netdev_alloc_frag into __alloc_page_frag and add __napi_alloc_frag")

[ Upstream commit 2c4cc97123 ]
ICMP handlers are not very often stressed, we should
make them more resilient to bugs that might surface in
the future.
If there is no packet in retransmit queue, we should
avoid a NULL deref.
