3 years agobuild: disable Windows warnings for insecure funtions
Nick Connolly [Sun, 29 Nov 2020 16:00:24 +0000 (16:00 +0000)]
build: disable Windows warnings for insecure funtions

Microsoft CRT defines Windows-specific secure alternatives to
standard library functions and triggers warnings when "insecure"
functions are used [1]. However, calling code already has all
necessary checks around those functions, so these warnings are not
useful for DPDK. MinGW provides its own CRT without this issue.

[1]:
https://docs.microsoft.com/en-us/cpp/c-runtime-library/security-features-in-the-crt?view=msvc-160

Disable this by defining -D_CRT_SECURE_NO_WARNINGS.

doc: announce flow API matching structs changes

Proposing to replace protocol header fields in the ``rte_flow_item_*``
structures with the protocol structs.

This is both for documenting the intention and to be sure
``rte_flow_item_*`` always starts with complete protocol header.

Change will be done in two steps, at first step in v21.02 release,
protocol header struct will be added as union, for example:

Current ``struct rte_flow_item_eth``,

struct rte_flow_item_eth {
struct rte_ether_addr dst;
struct rte_ether_addr src;
rte_be16_t type;
uint32_t has_vlan:1;
uint32_t reserved:31;
}

will become in v21.02:

__extension__
struct rte_flow_item_eth {
union {
struct {
struct rte_ether_addr dst;
struct rte_ether_addr src;
rte_be16_t type;
};
struct rte_ether_hdr hdr;
};
uint32_t has_vlan:1;
uint32_t reserved:31;
}

After this point usage should switch to 'hdr' struct.

And in the second step, in the v21.11 LTS release the protocol fields
will be removed, and the struct will become:

struct rte_flow_item_eth {
struct rte_ether_hdr hdr;
uint32_t has_vlan:1;
uint32_t reserved:31;
}

Already many ``rte_flow_item_*`` structures implemented to have protocol
struct, target is convert all to this usage.

doc: update flow API guide for rule removal on stop

There is a discrepancy between ethdev API and flow rules guide
regarding flow rules maintenance after port stop.
librte_ethdev.h declares that flow rules will not be stored in PMD
after port stop:
>>>>> Quote start
 Please note that some configuration is not stored between calls to
 rte_eth_dev_stop()/rte_eth_dev_start(). The following configuration
 will be retained:

 - MTU
 - flow control settings
 - receive mode configuration (promiscuous mode, all-multicast mode,
   hardware checksum mode, RSS/VMDQ settings etc.)
 - VLAN filtering configuration
 - default MAC address
 - MAC addresses supplied to MAC address array
 - flow director filtering mode (but not filtering rules)
 - NIC queue statistics mappings
<<<< Quote end

PMD cannot always correctly restore flow rules after port stop / port
start because application may alter port configuration after port stop
without PMD knowledge about undergoing changes.  Consider the
following scenario:
application configures 2 queues 0 and 1 and creates a flow rule with
'queue index 1' action. After that application stops the port and
removes queue 1.
Although PMD can implement flow rule shadow copy to be used for
restore after port start, attempt to restore flow rule from shadow
will fail in example above and PMD could not notify application about
that failure.  As the result, flow rules map in HW will differ from
what application expects.  In addition, flow rules shadow copy used
for port start restore consumes considerable amount of system memory,
especially in systems with millions of flow rules.

number of engines is called priv->nb_engines.
The id variable is of uint8_t type while the priv->nb_engines variable
is of uint32_t type. The size of the priv->nb_engines variable is much
larger than the number of iterations allowed by the id type.
Theoretically there may be a situation where the value of the
priv->nb_engines will be greater than can be represented by 8 bits and
the loop will never end.

Change the type of id to uint32_t.

4 years agoregex/mlx5: fix crash on probe failure

regex/mlx5: fix crash on probe failure

The mlx5_regex_pci_probe function allocates a mlx5_regex_priv structure
using rte_zmalloc.

If the allocation fails, the function jumps to the dev_error label in
order to release previously allocated resources in the function.
However, in the dev_error label it attempts to refer to the internal
fields of the priv structure and if its allocation fails (as in this
case) it is actually dereferencing to NULL.

Replace the jump with an error label.
