NetworkPkg: Refine casting expression result to bigger size There are cases that the operands of an expression are all with rank less than UINT64/INT64 and the result of the expression is explicitly cast to UINT64/INT64 to fit the target size. An example will be: UINT32 a,b; // a and b can be any unsigned int type with rank less than UINT64, like // UINT8, UINT16, etc. UINT64 c; c = (UINT64) (a + b); Some static code checkers may warn that the expression result might overflow within the rank of "int" (integer promotions) and the result is then cast to a bigger size. The commit refines codes by the following rules: 1). When the expression is possible to overflow the range of unsigned int/ int: c = (UINT64)a + b; 2). When the expression will not overflow within the rank of "int", remove the explicit type casts: c = a + b; 3). When the expression will be cast to pointer of possible greater size: UINT32 a,b; VOID *c; c = (VOID *)(UINTN)(a + b); --> c = (VOID *)((UINTN)a + b); 4). When one side of a comparison expression contains only operands with rank less than UINT32: UINT8 a; UINT16 b; UINTN c; if ((UINTN)(a + b) > c) {...} --> if (((UINT32)a + b) > c) {...} For rule 4), if we remove the 'UINTN' type cast like: if (a + b > c) {...} The VS compiler will complain with warning C4018 (signed/unsigned mismatch, level 3 warning) due to promoting 'a + b' to type 'int'.

/**
Set the security association, security policy and peer authorization configuration
information for the EFI IPsec driver.
This function is used to set the IPsec configuration information of type DataType for
the EFI IPsec driver.
The IPsec configuration data has a unique selector/identifier separately to identify
a data entry. The selector structure depends on DataType's definition.
Using SetData() with a Data of NULL causes the IPsec configuration data entry identified
by DataType and Selector to be deleted.
@param[in] This Pointer to the EFI_IPSEC_CONFIG_PROTOCOL instance.
@param[in] DataType The type of data to be set.
@param[in] Selector Pointer to an entry selector on operated configuration data
specified by DataType. A NULL Selector causes the entire
specified-type configuration information to be flushed.
@param[in] Data The data buffer to be set. The structure of the data buffer is
associated with the DataType.
@param[in] InsertBefore Pointer to one entry selector which describes the expected
position the new data entry will be added. If InsertBefore is NULL,
the new entry will be appended the end of database.
@retval EFI_SUCCESS The specified configuration entry data was set successfully.
@retval EFI_INVALID_PARAMETER One or more of the following are TRUE:
- This is NULL.
@retval EFI_UNSUPPORTED The specified DataType is not supported.
@retval EFI_OUT_OF_RESOURCED The required system resource could not be allocated.

/**
Enumerates the current selector for IPsec configuration data entry.
This function is called multiple times to retrieve the entry Selector in IPsec
configuration database. On each call to GetNextSelector(), the next entry
Selector are retrieved into the output interface.
If the entire IPsec configuration database has been iterated, the error
EFI_NOT_FOUND is returned.
If the Selector buffer is too small for the next Selector copy, an
EFI_BUFFER_TOO_SMALL error is returned, and SelectorSize is updated to reflect
the size of buffer needed.
On the initial call to GetNextSelector() to start the IPsec configuration database
search, a pointer to the buffer with all zero value is passed in Selector. Calls
to SetData() between calls to GetNextSelector may produce unpredictable results.
@param[in] This Pointer to the EFI_IPSEC_CONFIG_PROTOCOL instance.
@param[in] DataType The type of IPsec configuration data to retrieve.
@param[in, out] SelectorSize The size of the Selector buffer.
@param[in, out] Selector On input, supplies the pointer to last Selector that was
returned by GetNextSelector().
On output, returns one copy of the current entry Selector
of a given DataType.
@retval EFI_SUCCESS The specified configuration data was obtained successfully.
@retval EFI_INVALID_PARAMETER One or more of the followings are TRUE:
- This is NULL.
- SelectorSize is NULL.
- Selector is NULL.
@retval EFI_NOT_FOUND The next configuration data entry was not found.
@retval EFI_UNSUPPORTED The specified DataType is not supported.
@retval EFI_BUFFER_TOO_SMALL The SelectorSize is too small for the result. This parameter
has been updated with the size needed to complete the search
request.
