dm-bufio checks a watermark when it allocates a new buffer in
__bufio_new(). However, it doesn't check the watermark when the user
changes /sys/module/dm_bufio/parameters/max_cache_size_bytes.
This may result in a problem - if the watermark is high enough so that
all possible buffers are allocated and if the user lowers the value of
"max_cache_size_bytes", the watermark will never be checked against the
new value because no new buffer would be allocated.
To fix this, change __evict_old_buffers() so that it checks the
watermark. __evict_old_buffers() is called every 30 seconds, so if the
user reduces "max_cache_size_bytes", dm-bufio will react to this change
within 30 seconds and decrease memory consumption.

__get_memory_limit() tests if dm_bufio_cache_size changed and calls
__cache_size_refresh() if it did. It takes dm_bufio_clients_lock while
it already holds the client lock. However, lock ordering is violated
because in cleanup_old_buffers() dm_bufio_clients_lock is taken before
the client lock.
This results in a possible deadlock and lockdep engine warning.
Fix this deadlock by changing mutex_lock() to mutex_trylock(). If the
lock can't be taken, it will be re-checked next time when a new buffer
is allocated.
Also add "unlikely" to the if condition, so that the optimizer assumes
that the condition is false.

Vivien Didelot says:
====================
net: dsa: mv88e6xxx: 802.1s and 88E6390 VTU
This patch series adds support for the VLAN Table Unit (a.k.a. the VTU)
to the 88E6390 family of Marvell Ethernet switch chips. The plumbing for
the per VLAN Spanning Tree support is added as a side effect of the
necessary refactoring.
The patchset is split up so that no duplication of code is introduced.
With this patchset applied, the mv88e6xxx driver has 2 new function
pointers for the VTU GetNext and VTU Load/Purge operations (with 3
implementations), both handling programmation of 802.1q and 802.1s.
On a ZII Rev C board (featuring 2 88E6390X chips) with all ports bridged
together, we obtain the following hardware VLAN configuration:
# cat /sys/class/net/br0/bridge/vlan_filtering
1
# cat /sys/class/net/br0/bridge/default_pvid
42
# bridge vlan add dev lan3 vid 666
# bridge vlan show
port vlan ids

lan7 42 PVID Egress Untagged
lan8 42 PVID Egress Untagged
lan8 42 PVID Egress Untagged
br0 42 PVID Egress Untagged
Below are the technical details for the different implementations.
All switch families have up to 3 dedicated VTU Data registers used to
program 802.1q and 802.1s, both using 2-bit values.
On 88E6185 and 88E6352 families, port membership and state are adjacent,
while the 88E6390 family share the same bits:
Bits 88E6185/88E6352 88E6390
----- ----------------- --------------------------
0-1 Port 0 membership Port 0 membership or state
2-3 Port 0 state Port 1 membership or state
4-5 Port 1 membership Port 2 membership or state
6-7 Port 1 state Port 3 membership or state
8-9 Port 2 membership Port 4 membership or state
10-11 Port 2 state Port 5 membership or state
... ... ...
The 88E6185 family programs all ports membership and state in a single
VTU GetNext or Load/Purge operation.
The 88E6352 family introduced an indirect Spanning Tree Unit table
(a.k.a. STU) which requires additional STU GetNext and Load/Purge
operations to read and write the ports state bits.
The 88E6390 family also has an STU and requires data bits to be accessed
before and after every single VTU or STU operation.
Finally, the 88E6390 family introduced a 13th bit for the VLAN ID, which
must be taken care of regardless the VTU operating mode. This means that
iterating over the VTU now starts or ends with value 8191, not 4095.
Patch 1 adds a max_vid field to the chip info structure.
Patch 2 adds 802.1q and 802.1s data to the generic VTU entry structure.
Patches 3 to 10 move helpers to a dedicated file (later made static).
Patches 11 and 12 abstract handling of the STU behind VTU operations.
Patches 13 and 14 add the new function pointers for VTU operations.
Patches 15 and 18 polish the VTU code and add VTU support for 88E6390.
Changes in v2:
- add Reviewed-by tags
- fix comments in 8/18

The 6390 family of chips use only 2 of the 3 VTU Data registers to pack
the MemberTag and PortState VLAN data. This means that they must be
written or read before or after each VTU/STU operations.
Implement this variant to add support for VTU with such chips. These
chips have a 13th bit for the VID thus set their max_vid to 8191.

Newer chips such as the 88E6390 have a VTU Page bit in the VTU VID
register to specify a 13th bit for the VID. This can be used to support
8K VLANs.
When dumping the whole VTU, all VID bits must be set to one, including
this VTU Page bit. Add support for VID greater than 4095.

VLAN aware Marvell chips can program 802.1Q VLAN membership as well as
802.1s per VLAN Spanning Tree state using the same 3 VTU Data registers.
Some chips such as 88E6185 use different Data registers offsets for
ports state and membership, and program them in a single operation.
Other chips such as 88E6352 use the same register layout but program
them in distinct operations (an indirect table is used for 802.1s.)
Newer chips such as 88E6390 use the same offsets for both state and
membership in distinct operations, thus require multiple data accesses.
To correctly abstract this, split the "data" structure member of
mv88e6xxx_vtu_entry in two "state" and "member" members, before adding
VTU support for newer chips.

The IPv6 tunneling code tries to insert IPV6_TLV_TNL_ENCAP_LIMIT and
IPV6_TLV_PADN options when an encapsulation limit is defined (the
default is a limit of 4). An MTU adjustment is done to account for
these options as well. However, the options are never present in the
generated packets.
The issue appears to be a subtlety between IPV6_DSTOPTS and
IPV6_RTHDRDSTOPTS defined in RFC 3542. When the IPIP tunnel driver was
written, the encap limit options were included as IPV6_RTHDRDSTOPTS in
dst0opt of struct ipv6_txoptions. Later, ipv6_push_nfrags_opts was
(correctly) updated to require IPV6_RTHDR options when IPV6_RTHDRDSTOPTS
are to be used. This caused the options to no longer be included in v6
encapsulated packets.
The fix is to use IPV6_DSTOPTS (in dst1opt of struct ipv6_txoptions)
instead. IPV6_DSTOPTS do not have the additional IPV6_RTHDR requirement.

When reading a RDMA WRITE FIRST packet we copy the DMA length from the RDMA
header into the qp->resp.resid variable for later use. Later in check_rkey()
we clamp it to the MTU if the packet is an RDMA WRITE packet and has a
residual length bigger than the MTU. Later in write_data_in() we subtract the
payload of the packet from the residual length. If the packet happens to have a
payload of exactly the MTU size we end up with a residual length of 0 despite
the packet not being the last in the conversation. When the next packet in the
conversation arrives, we don't have any residual length left and thus set the QP
into an error state.
This broke NVMe over Fabrics functionality over rdma_rxe.ko
The patch was verified using the following test.

When the bit 26 of capmask2 field in OPA classport info
query is set, SA will query for OPA path records instead
of querying for IB path records. Note that OPA
path records can only be queried by kernel ULPs.
Userspace clients continue to query IB path records.

Add opa_sa_path_rec to sa_path_rec data structure.
The 'type' field in sa_path_rec identifies the

sa_path_rec now contains a union of sa_path_rec_ib and sa_path_rec_roce
based on the type of the path record. Note that fields applicable to
path record type ROCE v1 and ROCE v2 fall under sa_path_rec_roce.
Accessor functions are added to these fields so the caller doesn't have
to know the type.

struct sa_path_rec has a gid_type field. This patch introduces a more
generic path record specific type 'rec_type' which is either IB, ROCE v1
or ROCE v2. The patch also provides conversion functions to get
a gid type from a path record type and vice versa

Rename ib_sa_path_rec to a more generic sa_path_rec.
This is part of extending ib_sa to also support OPA
path records in addition to the IB defined path records.
