usage example:
proxy -s
proxy -s2
-s - enable splice() for sockets mapping to avoid data to be copied to user space
-s2 - enable splice() and attempt to free user space buffer ASAP
Supports _real_ name resolution via parent proxy over TCP in nserver /
dnspr.
Can be used to create UDP->TCP name proxy, e.g.
nserver 127.0.0.1/tcp
nscache 65535
auth none
dnspr
auth iponly
tcppm 53 77.88.8.8 53
now, all names are resolved via TCP connection to 77.88.8.8
(dns.yandex.ru).
! avoid errno usage due to compatibility issues (and never use errno as
a lvalue). socks changed to use internal error codes instead.
! NOIPV6 compilation issues solved
! -lite version is switched to NOIPV6
The buf gets copied to hostname and is present verbatim in logs looking
like pure random garbage. Moreover you can't really strlen() it.
This was likely some silly typo in inet_ntoa -> inet_ntop conversion for
ipv6, since it used to be correct before.
This used to look pretty random :(
Try to keep the last decimal digits of internal errors sensible for v5
error codes. For most cases we can't really do much better than using the
value of one.
One specific code paths where we can return something more useful is the
authentication, where we not communicate the underlying error code or
signal an ACL denial.
As for v4, there's not really much space to be too smart as only the code
of 91 is meaningful. Therefore we limit the last digit to zero and one now.
