This patch adds support for crypto4xx's ANSI X9.17 Annex C compliant
pseudo random number generator which provides a pseudo random source
for the purpose of generating Initialization Vectors (IV's) for AES
algorithms to the Packet Engine and other pseudo random number
requirements.

Add xcbc(aes) offloading support.
Due to xcbc algorithm design and HW implementation in CAAM,
driver must still have some bytes to send to the crypto engine when
ahash_final() is called - such that HW correctly uses either K2 or K3
for the last block.

For keyed hash algorithms, shared descriptors are currently generated
twice:
-at tfm initialization time, in cra_init() callback
-in setkey() callback
Since it's mandatory to call setkey() for keyed algorithms, drop the

There are several issues with symbols shared b/w:
-caam/jr and caam/qi drivers on one hand
-caam/qi2 driver on the other hand
Commit 52813ab249 ("crypto: caam/qi2 - avoid double export") fixed
some of them, however compilation still fails for CRYPTO_DEV_FSL_CAAM=m
and CRYPTO_DEV_FSL_DPAA2_CAAM=y.
Another issue is related to dependency cycles reported by depmod when
CRYPTO_DEV_FSL_CAAM=n and CRYPTO_DEV_FSL_DPAA2_CAAM=m, as mentioned in
82c7b351be ("Revert "arm64: defconfig: Enable FSL_MC_BUS and FSL_MC_DPIO"")
To fix all these, move the symbols shared by these drivers in a common
location. The only existing possibility is error.c file (note that naming
doesn't help and should probably change).

A long running stress test on a custom board shipping an AXG SoCs and a
Realtek RTL8211F PHY revealed that after a few hours the connection
speed would drop drastically, from ~1000Mbps to ~3Mbps. At the same time
the 'macirq' (eth0) IRQ would stop being triggered at all and as
consequence the GMAC IRQs never ACKed.
After a painful investigation the problem seemed to be due to a wrong
defined IRQ type for the GMAC IRQ that should be LEVEL_HIGH instead of
EDGE_RISING.
The change in the macirq IRQ type also solved another long standing
issue affecting this SoC/PHY where EEE was causing the network
connection to die after stressing it with iperf3 (even though much
sooner). It's now possible to remove the 'eee-broken-1000t' quirk as
well.

In the forward chain, the iif is changed from slave device to master vrf
device. Thus, flow offload does not find a match on the lower slave
device.
This patch uses the cached route, ie. dst->dev, to update the iif and
oif fields in the flow entry.
After this patch, the following example works fine:
# ip addr add dev eth0 1.1.1.1/24
# ip addr add dev eth1 10.0.0.1/24
# ip link add user1 type vrf table 1
# ip l set user1 up

The [ip,ip6,arp]_tables use x_tables_info internally and the underlying
memory is already accounted to kmemcg. Do the same for ebtables. The
syzbot, by using setsockopt(EBT_SO_SET_ENTRIES), was able to OOM the
whole system from a restricted memcg, a potential DoS.
By accounting the ebt_table_info, the memory used for ebt_table_info can
be contained within the memcg of the allocating process. However the
lifetime of ebt_table_info is independent of the allocating process and
is tied to the network namespace. So, the oom-killer will not be able to
relieve the memory pressure due to ebt_table_info memory. The memory for
ebt_table_info is allocated through vmalloc. Currently vmalloc does not
handle the oom-killed allocating process correctly and one large
allocation can bypass memcg limit enforcement. So, with this patch,
at least the small allocations will be contained. For large allocations,
we need to fix vmalloc.

besides, the users may still get successful return value without any

v2:
optimization:
- phy_set_max_speed() is only needed if you want to reduce the
max speed, typically if the PHY supports 1Gbps but the MAC
supports 100Mbps only.
- The pause parameters are autonegotiated. Except you have a specific
need you normally don't need to manually fiddle with this.
- phy_start_aneg() is called implicitly by the phylib state machine,
you shouldn't call it manually except you have a good excuse.
- netif_carrier_on/netif_carrier_off in mtk_phy_link_adjust() isn't
needed. It's done by phy_link_change() in phylib.

Previously upon SYN timeouts the sender recomputes the txhash to
try a different path. However this does not apply on the initial
timeout of SYN-data (active Fast Open). Therefore an active IPv6
Fast Open connection may incur one second RTO penalty to take on
a new path after the second SYN retransmission uses a new flow label.
This patch removes this undesirable behavior so Fast Open changes
the flow label just like the regular connections. This also helps
avoid falsely disabling Fast Open on the sender which triggers
after two consecutive SYN timeouts on Fast Open.

This tag contains a handful of updates that slipped through the cracks
during the merge window due to the holidays. The fixes are mostly
independent, with the exception of one larger audit-related branch.
There's more information about the audit branch in that merge, the rest
are:
* The BSS has been moved, which shrinks flat images.
* A fix to test-bpf so it compiles on RV64I-based systems.
* A fix to respect the kernel commandline when there is no device tree.
* A fix to prevent CPUs from trying to put themselves to sleep when
bringing down the system.
* Support for MODULE_SECTIONS on RV32I-based systems.
* [new in v2] The addition of an SBI earlycon driver. This is
definately a new feature, but I'd like to include it now because I
dropped this patch when submitting the merge window PR that removed our
EARLY_PRINTK support.
As usual, I've tested this by booting a Fedora-based image on a recent
QEMU (this time just whatever I had lying around).

Core RISC-V updates:
- The BSS has been moved, which shrinks flat images.
- A fix to test-bpf so it compiles on RV64I-based systems.
- A fix to respect the kernel commandline when there is no device
tree.
- A fix to prevent CPUs from trying to put themselves to sleep when
bringing down the system.
- Support for MODULE_SECTIONS on RV32I-based systems.
- [new in v2] The addition of an SBI earlycon driver. This is
definately a new feature, but I'd like to include it now because I
dropped this patch when submitting the merge window PR that removed
our EARLY_PRINTK support.
RISC-V audit updates:
- The addition of NR_syscalls into unistd.h, which is necessary for
CONFIG_FTRACE_SYSCALLS.
- The definition of CREATE_TRACE_POINTS so __tracepoint_sys_{enter,exit}
get defined.
- A fix for trace_sys_exit() so we can enable HAVE_SYSCALL_TRACEPOINTS
As usual, I've tested this by booting a Fedora-based image on a recent
QEMU (this time just whatever I had lying around).

In SMB3 protocol every part of the compound chain consumes credits
individually, so we need to call wait_for_free_credits() for each
of the PDUs in the chain. If an operation is interrupted, we must
ensure we return all credits taken from the server structure back.
Without this patch server can sometimes disconnect the session
due to credit mismatches, especially when first operation(s)
are large writes.

Currently we reset the number of total credits granted by the server
to 1 if the server didn't grant us anything int the response. This
violates the SMB3 protocol - we need to trust the server and use
the credit values from the response. Fix this by removing the
corresponding code.

Currently for MTU requests we allocate maximum possible credits
in advance and then adjust them according to the request size.
While we were adjusting the number of credits belonging to the
server, we were skipping adjustment of credits belonging to the
request. This patch fixes it by setting request credits to
CreditCharge field value of SMB2 packet header.
Also ask 1 credit more for async read and write operations to
increase parallelism and match the behavior of other operations.

The dm-crypt cipher specification in a mapping table is defined as:
cipher[:keycount]-chainmode-ivmode[:ivopts]
or (new crypt API format):
capi:cipher_api_spec-ivmode[:ivopts]
For ESSIV, the parameter includes hash specification, for example:
aes-cbc-essiv:sha256
The implementation expected that additional IV option to never include
another dash '-' character.
But, with SHA3, there are names like sha3-256; so the mapping table
parser fails:
dmsetup create test --table "0 8 crypt aes-cbc-essiv:sha3-256 9c1185a5c5e9fc54612808977ee8f5b9e 0 /dev/sdb 0"

A side effect of commit c55191e96c ("arm64: mm: apply r/o permissions
of VM areas to its linear alias as well") is that the linear map is
created with page granularity, which means that transitioning the early
page table from global to non-global mappings when enabling kpti can
take a significant amount of time during boot.
Given that most CPU implementations do not require kpti, this mainly
impacts KASLR builds where kpti is forcefully enabled. However, in these
situations we know early on that non-global mappings are required and
can avoid the use of global mappings from the beginning. The only gotcha
is Cavium erratum #27456, which we must detect based on the MIDR value
of the boot CPU.

One of the more common cases of allocation size calculations is finding the
size of a structure that has a zero-sized array at the end, along with
memory for some number of elements for that array. For example:
struct foo {
int stuff;
void *entry[];
};
instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can now
use the new struct_size() helper:
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);
This code was detected with the help of Coccinelle.

[BUG]
Linux v5.0-rc1 will fail fstests/btrfs/163 with the following kernel
message:
BTRFS error (device dm-6): dev extent devid 1 physical offset 13631488 len 8388608 is beyond device boundary 0
BTRFS error (device dm-6): failed to verify dev extents against chunks: -117
BTRFS error (device dm-6): open_ctree failed
[CAUSE]
Commit cf90d884b3 ("btrfs: Introduce mount time chunk <-> dev extent
mapping check") introduced strict check on dev extents.
We use btrfs_find_device() with dev uuid and fs uuid set to NULL, and
only dependent on @devid to find the real device.
For seed devices, we call clone_fs_devices() in open_seed_devices() to
allow us search seed devices directly.
However clone_fs_devices() just populates devices with devid and dev
uuid, without populating other essential members, like disk_total_bytes.
This makes any device returned by btrfs_find_device(fs_info, devid,
NULL, NULL) is just a dummy, with 0 disk_total_bytes, and any dev
extents on the seed device will not pass the device boundary check.
[FIX]
This patch will try to verify the device returned by btrfs_find_device()
and if it's a dummy then re-search in seed devices.

devm_kzalloc(), devm_kstrdup() and devm_kasprintf() all can
fail internal allocation and return NULL. Using any of the assigned
objects without checking is not safe. As this is early in the boot
phase and these allocations really should not fail, any failure here
is probably an indication of a more serious issue so it makes little
sense to try and rollback the previous allocated resources or try to
continue; but rather the probe function is simply exited with -ENOMEM.
