crypto/aesni_mb: support all truncated HMAC digest sizes

HMAC algorithms (MD5 and SHAx) have different full digest sizes.
However, they are often truncated to a smaller size (such as in IPSec).
This commit allows a user to generate a digest of any size
up to the full size.

6 years agocrypto/aesni_mb: fix possible array overrun
Pablo de Lara [Thu, 2 Aug 2018 04:49:40 +0000 (05:49 +0100)]
crypto/aesni_mb: fix possible array overrun

In order to process crypto operations in the AESNI MB PMD,
they need to be sent to the buffer manager of the Multi-buffer library,
through the "job" structure.

Currently, it is checked if there are outstanding operations to process
in the ring, before getting a new job. However, if there are no available
jobs in the manager, a flush operation needs to take place, freeing some
of the jobs, so it can be used for the outstanding operation.

In order to avoid leaving the dequeued operation without being processed,
the maximum number of operations that can be flushed is the remaining
operations to return, which is the maximum number of operations that can
be return minus the number of operations ready to be returned
(nb_ops - processed_jobs), minus 1 (for the new operation).

The problem comes when (nb_ops - processed_jobs) is 1 (last operation to
dequeue). In that case, flush_mb_mgr is called with maximum number of
operations equal to 0, which is wrong, causing a potential overrun in the
"ops" array.
Besides, the operation dequeued from the ring will be leaked, as no more
operations can be returned.

The solution is to first check if there are jobs available in the manager.
If there are not, flush operation gets called, and if enough operations
are returned from the manager, then no more outstanding operations get
dequeued from the ring, avoiding both the memory leak and the array
overrun.
If there are enough jobs, PMD tries to dequeue an operation from the ring.
If there are no operations in the ring, the new job pointer is not used,
and it will be used in the next get_next_job call, so no memory leak
happens.

6 years agonet/sfc/base: improve handling of legacy RSS hash flags
Ivan Malov [Mon, 10 Sep 2018 09:33:33 +0000 (10:33 +0100)]
net/sfc/base: improve handling of legacy RSS hash flags

Client drivers may use either legacy flags, for example,
EFX_RX_HASH_TCPIPV4, or generalised flags, for example,
EFX_RX_HASH(IPV4_TCP, 4TUPLE), to configure RSS hash.
The libefx is able to recognise what scheme is used.

Legacy flags may be consumed directly by a chip-specific handler to
configure the NIC, that is, on EF10, these flags can be used to fill
in legacy RSS mode field in MCDI request. Generalised flags can also
be directly used in EF10-specific handler as they are fully compatible
with additional fields of the same MCDI request.

Legacy flags undergo conversion to generalised flags before they
are consumed by a chip-specific handler. This conversion is used to
make sure that chip-specific handlers expect only generalised flags
in the input for the sake of clarity of the code.

Depending on firmware capabilities, a chip-specififc handler either
supplies the input to the NIC directly, for example,
EFX_RX_HASH(IPV4_TCP, 4TUPLE) flag will enable 4 bits in
RSS_CONTEXT_SET_FLAGS_IN_TCP_IPV4_RSS_MODE field on EF10, or takes
the opportunity to translate the input to enable bits which don't map
to the generic flag, like setting
RSS_CONTEXT_SET_FLAGS_IN_TOEPLITZ_TCPV4_EN on EF10 when the firmware
claims no support for additional modes.

However, this approach has introduced a severe problem which can be
reproduced with ultra-low-latency firmware variant. In order to enable
IP hash, EF10-specific handler requires the user to request 2-tuple
hash for IP-other, TCP and UDP traffic classes, unconditionally.
In example, IPv4 hash can be enabled using the following input:
EFX_RX_HASH(IPV4_TCP, 2TUPLE) | EFX_RX_HASH(IPV4_UDP, 2TUPLE) |
EFX_RX_HASH(IPV4, 2TUPLE).
At the same time, on ultra-low-latency firmware, the common code will
never report support for any UDP tuple to the client driver. That is,
in the same example, the driver will use EFX_RX_HASH(IPV4_TCP, 2TUPLE) |
EFX_RX_HASH(IPV4, 2TUPLE). This input will not be recognised by
EF10-specific handler, and RSS_CONTEXT_SET_FLAGS_IN_TOEPLITZ_IPV4_EN
bit will not be set in the MCDI request.

In order to solve the problem, the patch removes conversion code
from chip-specific handlers and adds appropriate code to convert
EFX_RX_HASH() flags to their legacy counterparts to the common scale
mode set function. If the firmware does not support additional modes,
the function will convert generalised flags to legacy flags correctly
without any demand for UDP flags and pass the result to a chip-specific
handler.
