2019-06-13Wifi-Hal: Avoid accessing invalid memory while parsing pkt statsAjit Vaishya
Current implementation of packet stats parsing isn't validating remaining buflen, which might lead to accessing invalid memory location while parsing. To address this issue, we need to check whether received buflen is sufficient to parse the stat before reading the stats from nlmsg. While parsing pkt stats, the bufflen shall be decremented for all versions of packet log records. Add logic to decrement buflen for the missed versions also.

2019-06-10WIFIHAL: Fix use-after-free issue while freeing monitor socket listVinay Gannevaram
During cleanup of monitor socket list, entries are freed with out being deleted from the list. This results in accessing memory which was already freed. Hence deleting the entry before freeing it, so that list would have only valid entries.

2019-04-19Wifi-Hal: Pass the address of the global variable to NL callbackAjit Vaishya
Current implementation passes the address of a local variable to the netlink control block callback, ending up to go out of scope if the callback is invoked after the scope for the current function ends (from where the registration happened), resulting in an invalid memory access. Address this issue by having the respective variable defined with a global scope. Change-Id: Ied10a8f17f20326864f80ac40b0ceac6791f6cd1 CRs-Fixed: 2427930 Bug: 129092516 Test: Manual test
