Prior to this change we would assume the ABI for Apple targets to be GNU which could result in subtle errors in LLVM emitting calls to non-existent system libc provided functions such as `_sincosf` which is a GNU extension and as such is not provided by macOS for example. This would result in linker errors where the linker would not be able to find the said symbol in `libSystem.tbd`. With this change, we now correctly identify macOS (and other Apple platforms) as having ABI `unknown` which translates to unspecified in LLVM under-the-hood: ``` // main.ll target triple = "aarch64-unknown-macos-unknown" ``` Note however that we never suffix the target OS with target version such as `macos11` or `macos12` which means we fail to instruct LLVM of potential optimisations provided by the OS such as the availability of function `___sincosf_stret`. I suggest we investigate that in a follow-up commit.

* Network Service Type for option SO_NET_SERVICE_TYPE
|
|
*
|
|
* The vast majority of sockets should use Best Effort that is the default
|
|
* Network Service Type. Other Network Service Types have to be used only if
|
|
* the traffic actually matches the description of the Network Service Type.
|
|
*
|
|
* Network Service Types do not represent priorities but rather describe
|
|
* different categories of delay, jitter and loss parameters.
|
|
* Those parameters may influence protocols from layer 4 protocols like TCP
|
|
* to layer 2 protocols like Wi-Fi. The Network Service Type can determine
|
|
* how the traffic is queued and scheduled by the host networking stack and
|
|
* by other entities on the network like switches and routers. For example
|
|
* for Wi-Fi, the Network Service Type can select the marking of the
|
|
* layer 2 packet with the appropriate WMM Access Category.
|
|
*
|
|
* There is no point in attempting to game the system and use
|
|
* a Network Service Type that does not correspond to the actual
|
|
* traffic characteristic but one that seems to have a higher precedence.
|
|
* The reason is that for service classes that have lower tolerance
|
|
* for delay and jitter, the queues size is lower than for service
|
|
* classes that are more tolerant to delay and jitter.
|
|
*
|
|
* For example using a voice service type for bulk data transfer will lead
|
|
* to disastrous results as soon as congestion happens because the voice
|
|
* queue overflows and packets get dropped. This is not only bad for the bulk
|
|
* data transfer but it is also bad for VoIP apps that legitimately are using
|
|
* the voice service type.
|
|
*
|
|
* The characteristics of the Network Service Types are based on the service
|
|
* classes defined in RFC 4594 "Configuration Guidelines for DiffServ Service
|
|
* Classes"
|
|
*
|
|
* When system detects the outgoing interface belongs to a DiffServ domain
|
|
* that follows the recommendation of the IETF draft "Guidelines for DiffServ to
|
|
* IEEE 802.11 Mapping", the packet will marked at layer 3 with a DSCP value
|
|
* that corresponds to Network Service Type.
|
|
*
|
|
* NET_SERVICE_TYPE_BE
|
|
* "Best Effort", unclassified/standard. This is the default service
|
|
* class and cover the majority of the traffic.
|
|
*
|
|
* NET_SERVICE_TYPE_BK
|
|
* "Background", high delay tolerant, loss tolerant. elastic flow,
|
|
* variable size & long-lived. E.g: non-interactive network bulk transfer
|
|
* like synching or backup.
|
|
*
|
|
* NET_SERVICE_TYPE_RD
|
|
* "Responsive Data", a notch higher than "Best Effort", medium delay
|
|
* tolerant, elastic & inelastic flow, bursty, long-lived. E.g. email,
|
|
* instant messaging, for which there is a sense of interactivity and
|
|
* urgency (user waiting for output).
|
|
*
|
|
* NET_SERVICE_TYPE_OAM
|
|
* "Operations, Administration, and Management", medium delay tolerant,
|
|
* low-medium loss tolerant, elastic & inelastic flows, variable size.
|
|
* E.g. VPN tunnels.
|
|
*
|
|
* NET_SERVICE_TYPE_AV
|
|
* "Multimedia Audio/Video Streaming", medium delay tolerant, low-medium
|
|
* loss tolerant, elastic flow, constant packet interval, variable rate
|
|
* and size. E.g. video and audio playback with buffering.
|
|
*
|
|
* NET_SERVICE_TYPE_RV
|
|
* "Responsive Multimedia Audio/Video", low delay tolerant, low-medium
|
|
* loss tolerant, elastic flow, variable packet interval, rate and size.
|
|
* E.g. screen sharing.
|
|
*
|
|
* NET_SERVICE_TYPE_VI
|
|
* "Interactive Video", low delay tolerant, low-medium loss tolerant,
|
|
* elastic flow, constant packet interval, variable rate & size. E.g.
|
|
* video telephony.
|
|
*
|
|
* NET_SERVICE_TYPE_SIG
|
|
* "Signaling", low delay tolerant, low loss tolerant, inelastic flow,
|
|
* jitter tolerant, rate is bursty but short, variable size. E.g. SIP.
|
|
*
|
|
* NET_SERVICE_TYPE_VO
|
|
* "Interactive Voice", very low delay tolerant, very low loss tolerant,
|
|
* inelastic flow, constant packet rate, somewhat fixed size.
|

* E.g. VoIP.
