wimax/i2400m: fix a memory leak bug

2019-08-18T21:11:28+00:00

In i2400m_barker_db_init(), 'options_orig' is allocated through kstrdup()
to hold the original command line options. Then, the options are parsed.
However, if an error occurs during the parsing process, 'options_orig' is
not deallocated, leading to a memory leak bug. To fix this issue, free
'options_orig' before returning the error.

wimax/i2400m: use struct_size() helper

2019-05-04T04:04:31+00:00

Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.

So, replace code of the following form:

sizeof(*tx_msg) + le16_to_cpu(tx_msg->num_pls) * sizeof(tx_msg->pld[0]);

with:

struct_size(tx_msg, pld, le16_to_cpu(tx_msg->num_pls));

This code was detected with the help of Coccinelle.

wimax/i2400m/control: Mark expected switch fall-through

2019-04-26T15:28:47+00:00

In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.

This patch fixes the following warning:

wimax/i2400m: use struct_size() helper

2019-02-09T06:57:28+00:00

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    void *entry[];
};

size = sizeof(struct foo) + count * sizeof(void *);
instance = alloc(size, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

size = struct_size(instance, entry, count);

This code was detected with the help of Coccinelle.

and remove confusing "not" from the error text since the error code

Notice that in this particular case, I placed the "fall through"
annotation at the bottom of the case, which is what GCC is expecting
to find.
