Chrome has started being able to issue frame type 0x42, we drop the connection
before we realize we wanted to ignore it.
This explicitly ignores it a bit earlier.
When ss is proxied, the handle CREATING state is deferred until the handle links up
to the proxy. So user code should only start using it when it sees CREATING. If it
tries to use it before then, we won'tget anywhere but we should make sure not to crash
on the NULL proxy link cwsi.
Fix an assumption about h2 being around if h1 is that crept in.
Add a sai scenario to catch this kind of problem, only needs one
build since testing lws' own consistency... add WITH_MINIMAL_EXAMPLES
as well
role ops are usually only sparsely filled, there are currently 20
function pointers but several roles only fill in two. No single
role has more than 14 of the ops. On a 32/64 bit build this part
of the ops struct takes a fixed 80 / 160 bytes then.
First reduce the type of the callback reason part from uint16_t to
uint8_t, this saves 12 bytes unconditionally.
Change to a separate function pointer array with a nybble index
array, it costs 10 bytes for the index and a pointer to the
separate array, for 32-bit the cost is
2 + (4 x ops_used)
and for 64-bit
6 + (8 x ops_used)
for 2 x ops_used it means 32-bit: 10 vs 80 / 64-bit: 22 vs 160
For a typical system with h1 (9), h2 (14), listen (2), netlink (2),
pipe (1), raw_skt (3), ws (12), == 43 ops_used out of 140, it means
the .rodata for this reduced from 32-bit: 560 -> 174 (386 byte
saving) and 64-bit: 1120 -> 350 (770 byte saving)
This doesn't account for the changed function ops calling code, two
ways were tried, a preprocessor macro and explicit functions
For an x86_64 gcc 10 build with most options, release mode,
.text + .rodata
before patch: 553282
accessor macro: 552714 (568 byte saving)
accessor functions: 553674 (392 bytes worse than without patch)
therefore we went with the macros
RFC6724 defines an ipv6-centric DNS result sorting algorithm, that
takes route and source address route information for the results
given by the DNS resolution, and sorts them in order of preferability,
which defines the order they should be tried in.
If LWS_WITH_NETLINK, then lws takes care about collecting and monitoring
the interface, route and source address information, and uses it to
perform the RFC6724 sorting to re-sort the DNS before trying to make
the connections.
Gencrypto needs work to adapt against deprecated openssl 3 apis (about
100 apis). But we can still test it without gencrypto, for use with
socket connections generally, where it is working.
OSX changed to blow a segfault on write to .rodata, exposing that
we're dropping a NUL in what can be .rodata to set the environment
manually. We don't do this on Linux typically because we take the
code path where execvpe() is available to do the env for us.
Adapt the code to treat it as const, and underscore it by changing
its type to be const char ** in the info struct.
This creates a role for RFC3549 Netlink monitoring.
If the OS supports it (currently, linux) then each pt creates a wsi
with the netlink role and dumps the current routing table at pt init.
It then maintains a cache of the routing table in each pt.
Upon routing table changes an SMD message is issued as an event, and
Captive Portal Detection is triggered.
All of the pt's current connections are reassessed for routability under
the changed routing table, those that no longer have a valid route or
gateway are closed.
This adds a helper to test if an sa46 is on an sa46-based subnet.
The compare helper is adapted to say that non INET/INET6 addresses with
the same AF match.
If we connect out to an IP address, or we adopt a connected socket,
from now on we want to hold the peer sockaddr in the wsi.
Adapt ACCESS_LOG to use this new copy rather than keep the
stringified version.
The cmake define isn't exported, and msvc objects to void * comparision to
non void *.
Also dump the callback pointer with any errors, since after looking it up
in your mapfile this is usually enough to understand which sul and when it
was set.
