There are as many divergent implementations of sys/queue.h as there
are operating systems shipping it, it would seem. They have some code
in common, but have drifted apart, and have added other stuff named
differently. So I'm taking a relatively sane one, and hoping for the
best.
I'm taking OpenBSD's in particular because of the lack of external
dependencies, the presence of a CIRCLEQ (we could use one of those in
places), and the liberal licensing terms.
I'm naming the file tor_queue.h, since historically we've run into
trouble having headers with the same names as system headers (log.h,
for example.)
The rationale for treating these files differently is that we should
be checking upstream for changes as applicable, and merging changes
upstream as warranted.
Conflicts:
src/or/circuitbuild.c
The conflict was trivial, since no line of code actually changed in
both branches: There was a fmt_addr() that turned into fmt_addrport()
in bug7011, and a "if (!n_conn)" that turned into "if (!n_chan)" in
master.
They're typically redundant with the "Your computer is too slow"
messages. Fixes bug 7038; bugfix on 0.2.2.16-alpha.
(In retrospect, we should have fixed this bug back in ticket 1042.)
We used to never return an IPv6 address unless ClientUseIPv6 was
set. We should allow clients running with bridges use IPv6 OR ports
even without setting ClientUseIPv6. Configuring an IPv6 address in a
Bridge line should imply that.
Fixes th second part of #6757.
Look at the address family of the preferred OR port rather than the
node.ipv6_preferred flag since the logic has changed with new
ClientUseIPv6 config option.
Fixes ticket 6884.
Right-shifting negative values has implementation-defined behavior.
On all the platforms we work on right now, the behavior is to
sign-extend the input. That isn't what we wanted in
auth_type_val = (descriptor_cookie_tmp[16] >> 4) + 1;
Fix for 6861; bugfix on 0.2.1.5-alpha; reported pseudonymously.
The broken behavior didn't actually hurt anything, I think, since the
only way to get sign-extension to happen would be to have the top bit
of descriptor_cookie_tmp[16] set, which would make the value of
descriptor_cookie_tmp[16] >> 4 somewhere between 0b11111111 and
0b11111000 (that is, between -1 and -8). So auth_type_val would be
between -7 and 0. And the immediate next line does:
if (auth_type_val < 1 || auth_type_val > 2) {
So the incorrectly computed auth_type_val would be rejected as
invalid, just as a correctly computed auth_type_val would be.
Still, this stuff shouldn't sit around the codebase.
We were doing (1<<p) to generate a flag at position p, but we should
have been doing (U64_LITERAL(1)<<p).
Fixes bug 6861; bugfix on 0.2.0.3-alpha; reported pseudonymously.
We already had code on windows to fix our file sizes when we're
reading a file in text mode and its size doesn't match the size from
fstat. But that code was only enabled when _WIN32 was defined, and
Cygwin defines __CYGWIN__ instead.
Fixes bug 6844; bugfix on 0.1.2.7-alpha.
