Remove some pointless casts from the return value of strlen(). The
"buflen" variable is already an unsigned int so it's never less than
zero and doesn't need to be casted to u32.

Internally we reworked this code and moved the function to another file.
The casts are no longer there.
if (bssidx == 0)
return brcmf_c_mkiovar(name, data, datalen, buf, buflen);
- prefixlen = (u32) strlen(prefix); /* lengh of bsscfg prefix */
- namelen = (u32) strlen(name) + 1; /* lengh of iovar name + null */
+ prefixlen = strlen(prefix); /* lengh of bsscfg prefix */
+ namelen = strlen(name) + 1; /* lengh of iovar name + null */
iolen = prefixlen + namelen + sizeof(bssidx_le) + datalen;
- if (buflen < 0 || iolen > (u32)buflen) {
+ if (buflen < iolen) {
This is still wrong internally so we will fix this with the appropriate
credits ;-)
brcmf_dbg(ERROR, "buffer is too short\n");
return 0;
}
Thanks.
