Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

Check upon `num_rsp` is insufficient. A malformed event packet with a large `num_rsp` number makes hci_extended_inquiry_result_evt() go out of bounds. Fix it.

Even with one advertisement monitor in place, the scan policy should use the whitelist while the system is going to suspend to prevent waking by random advertisement. The following test was performed. - With a paired device, register one advertisement monitor, suspend the system and verify that the host was not awaken by random advertisements. Signed-off-by:

This calls hci_update_background_scan() when there is any update on the advertisement monitors. If there is at least one advertisement monitor, the filtering policy of scan parameters should be 0x00. This also reports device found mgmt events if there is at least one monitor. The following cases were tested with btmgmt advmon-* commands. (1) add a ADV monitor and observe that the passive scanning is triggered. (2) remove the last ADV monitor and observe that the passive scanning is terminated. (3) with a LE peripheral paired, repeat (1) and observe the passive scanning continues. (4) with a LE peripheral paired, repeat (2) and observe the passive scanning continues. (5) with a ADV monitor, suspend/resume the host and observe the passive scanning continues. Signed-off-by:
