gone for replacing the implicit casts with explicit ones. Where there was
something obviously better that I could do, I've done it, though.
[originally from svn r2460]
general logging module rather than localising it in ssh.c. This
means it should work in other protocols as well (notably Telnet,
where it might actually be useful for debugging negotiations).
[originally from svn r2360]
SockAddr, which just contains an unresolved hostname and is created
by a stub function in *net.c. It's an error to pass this to most of
the real-meat functions in *net.c; these fake addresses should have
been dealt with by the time they get down that far. proxy.c now
contains name_lookup(), a wrapper on sk_namelookup() which decides
whether or not to do real DNS, and the individual proxy
implementations each deal sensibly with being handed an unresolved
address and avoid ever passing one down to *net.c.
[originally from svn r2353]
well, though it's a lot less useful since you still can't bind to
low-numbered ports of odd loopback IPs. Should work in principle for
SSH2 remote forwardings as well as local ones, but OpenSSH seems
unwilling to cooperate.
[originally from svn r2344]
same behaviour as before (tested a little bit), but should be easier to
expand.
(This is the easy bit -- work still needs to be done to fix
ssh2-keyderive-nonbug, vshell-no-bug-compat, etc -- but should be easier
now.)
[originally from svn r2293]
source files in which it's no longer required (it was previously
required in anything that included <putty.h>, but not any more).
Also moved a couple of stray bits of exposed WinSock back into
winnet.c (getservbyname from ssh.c and AF_INET from proxy.c).
[originally from svn r2160]
That'd have been embarrassing. Mind you I'd like to remove this
particular #include for good anyway, but the time is not now...
[originally from svn r2158]
absent, and also (I think) all the frontend request functions (such
as request_resize) take a context pointer, so that multiple windows
can be handled sensibly. I wouldn't swear to this, but I _think_
that only leaves the Unicode stuff as the last stubborn holdout.
[originally from svn r2147]
lpage_send out into the line discipline, making them _clients_ of
the Unicode layer rather than part of it. This means they can access
ldisc->term, which in turn means I've been able to remove the
temporary global variable `term'. We're slowly getting there.
[originally from svn r2143]
As a result I've now been able to turn the global variables `back'
and `backhandle' into module-level statics in the individual front
ends. Now _that's_ progress!
[originally from svn r2142]
each backend now stores all its internal variables in a big struct,
and each backend function gets a pointer to this struct passed to
it. This still isn't the end of the work - lots of subsidiary things
still use globals, notably all the cipher and compressor modules and
the X11 forwarding authentication stuff. But ssh.c itself has now
been transformed, and that was the really painful bit, so from here
on it all ought to be a sequence of much smaller and simpler pieces
of work.
[originally from svn r2127]
terminal.c was apparently relying on implicit initialisation to
zero, and also I've removed the backends' dependency on terminal.h
by having terminal sizes explicitly passed in to back->size().
[originally from svn r2117]
all the global and function-static variables out of terminal.c into
a dynamically allocated data structure. Note that this does not yet
confer the ability to run more than one of them in the same process,
because other things (the line discipline, the back end) are still
global, and also in particular the address of the dynamically
allocated terminal-data structure is held in a global variable
`term'. But what I've got here represents a reasonable stopping
point at which to check things in. In _theory_ this should all still
work happily, on both Unix and Windows. In practice, who knows?
[originally from svn r2115]
longer just sit there like a lemon if we can't find the channel in
question, we bomb out and complain. With any luck, remaining
problems of this type should be easier to catch under this policy.
[originally from svn r1962]
receiving of CLOSE and CLOSE_CONFIRMATION separately rather than
taking short cuts. I believe ssh-1.2.33 sending CLOSE_CONFIRMATION
before CLOSE was causing the remaining incidences of bug
`nonexistent-channel'. (ssh-1.2.33 appears to have unilaterally
decreed that CLOSE and CLOSE_CONFIRMATION are respectively renamed
INPUT_EOF and OUTPUT_CLOSING, hence there is no longer an ordering
constraint on them. Bah.)
[originally from svn r1961]
Bump username storage from 32 to 100 chars. Also replaced a couple of magic
numbers with sizeof in ssh.c.
I don't believe this is going to startle any of the protocols PuTTY talks.
[originally from svn r1952]
versions 2.0.*, and causing the shared secret not to be included in
key derivation hashes. (This doesn't quite cause a blatant security
hole because the session ID - _derived_ from the shared secret - is
still included.)
[originally from svn r1853]
subsequent packet-receiver code would fail to notice anything was
wrong and segfault. Since this is clearly a silly packet length
anyway, we now explicitly reject it as a daft encryption error.
[originally from svn r1852]
containing more than one prompt instead of less than one, and also
correctly enables echo on prompts that the server requests it for.
In the process I've moved the whole username/password input routine
out into its own function, where it's called independently of which
SSH protocol we're using, so this should even have _saved_ code
size. Rock!
