MTU is used in testpmd to set the maximum payload size for packets.

In rte_ethdev there's no relation between MTU setting and JUMBO offload

The previous fix in patch referenced below was meant to update the

it assumes that MTU setting can only exist when JUMBO offload supported

doesn't support JUMBO offload, and in this case, though set MTU
succeeds, an error message is still printed since the JUMBO packet
offload is disabled.

The fix separates the two conditions to make sure the error
triggers only in case the set_mtu action actually failed.

buffers functionality. Each memzone is 2Mb in size and divided among
the pool of external memory buffers.

Memzone may not always be fully utilized because mbufs size can vary

not handled properly and mbuf can get the address of this leftover
space since this address is still valid (part of memzone), but there
is not enough space to fit the whole packet data. As a result packet
data may overflow and cause the memory corruption.

Take mbuf size into account when distributing memory addresses from
a memzone to external mbufs. Skip the remaining tail in case there
is not enough room for a packet and move to a next memzone instead.

net/mlx5: remove needless Tx queue initialization check

The mlx5_txq_obj_new function defines a pointer named txq_data and
assign value into it. After assigning, the code writer is sure that the
variable does not point to NULL and even express it using assertion.

During the function, the function does dereferencing to the pointer
several times and at no point change its value. However, at the end of
the function at the error label when it wants to free one of the fields
of the structure that txq_data points to, it checks again whether
txq_data is invalid.
This check is unnecessary since it knows for sure that txq_data is
valid.

Remove the aforementioned needless check.

4 years agonet/mlx5: fix socket close

net/mlx5: fix socket close

The mlx5_pmd_socket_handle function calls the accept function that
returns the socket descriptor into the conn_sock variable. The socket
descriptor value can be 0 (according to accept API) or positive and so
immediately after calling the function it checks whether conn_sock < 0.
Later in the function when other things fail it jumps to the error label
and release previously allocated resources (such as socket or file).

During the resource release, it checks whether the variable conn_sock
containing the socket descriptor is positive and if it is, it releases
it. However, in this check it misses the case where conn_sock == 0, in
this case the socket will not be released and there will be a Resource
leak.

Extend the close condition for 0 value too.

4 years agonet/mlx5: remove unnecessary init in socket creation

net/mlx5: remove unnecessary init in socket creation

In the mlx5_pmd_socket_handle function it calls the recvmsg function
which returns the number of bytes read. The function assigns this return
value into a ret variable defined at the beginning of the function.
Similarly in the mlx5_pmd_socket_init function the it calls the socket
function which returns a file descriptor for the new socket. The
function also assigns this return value into a ret variable defined at
the beginning of the function.

In both functions they initialize the variable when defining it,
however, in both cases they do not use any ret variable before assigning
the return value from the function, so the initialization is
unnecessary.

Clean the aforementioned unnecessary initializations.

net/mlx5: fix hairpin Rx queue creation error path

The mlx5_rxq_obj_hairpin_new function defines a pointer named tmpl and

Later, this function allocates memory to a variable inside tmpl using
the mlx5_devx_cmd_create_rq function.

In both cases, if the allocation fails, the code jumps to the error
label and frees allocated resources. However, in the first jump there
are still no resources to free and the jump only for the line return
NULL is unnecessary. Even worse, when it jumps to error label with
invalid tmpl it actually does dereference to a null pointer.
In contrast, the second jump needs to free the tmpl variable but the
function instead of freeing, tries to free the variable that it just
failed to allocate.
In addition, for another error, the function returns NULL without
freeing the tmpl variable before, causing a memory leak.

Delete the error label and replace each jump with local return NULL and
