Just looking at the "latest" consensus could give us a microdesc
consensus, if microdescs were enabled. That would make us decide
that every routerdesc was unlisted in the latest consensus and drop
them all: Ouch.
Fixes bug 3113; bugfix on 0.2.3.1-alpha.
We have an invariant that a node_t should have an md only if it has
a routerstatus. nodelist_purge tried to preserve this by removing
all nodes without a routerstatus or a routerinfo. But this left
nodes with a routerinfo and a microdesc untouched, even if they had
a routerstatus.
Bug found by frosty_un.
All of the routerset_contains*() functions return 0 if their
routerset_t argument is NULL. Therefore, there's no point in
doing "if (ExcludeNodes && routerset_contains*(ExcludeNodes...))",
for example.
This patch fixes every instance of
if (X && routerstatus_contains*(X,...))
Note that there are other patterns that _aren't_ redundant. For
example, we *don't* want to change:
if (EntryNodes && !routerstatus_contains(EntryNodes,...))
Fixes#2797. No bug here; just needless code.
Previously, we'd get a new descriptor for free when
public_server_mode() changed, since it would count as
affects_workers, which would call init_keys(), which would make us
regenerate a new descriptor. But now that we fixed bug 3263,
init_keys() is no longer necessarily a new descriptor, and so we
need to make sure that public_server_mode() counts as a descriptor
transition.
The issue was that we overlooked the possibility of reverse DNS success
at the end of connection_ap_handshake_socks_resolved(). Issue discovered
by katmagic, thanks!
Returning a tristate is needless here; we can just use the yielded
transport/proxy_type field to tell whether there's a proxy, and have
the return indicate success/failure.
Also, store the proxy_type in the or_connection_t rather than letting
it get out of sync if a configuration reload happens between launching
the or_connection and deciding what to say with it.
- const-ify some transport_t pointers
- Remove a vestigial argument to parse_bridge_line
- Make it compile without warnings on my laptop with
--enable-gcc-warnings
We were using strncpy before, which isn't our style for stuff like
this.
This isn't a bug, though: before calling strncpy, we were checking
that strlen(src) was indeed == HEX_DIGEST_LEN, which is less than
sizeof(dst), so there was no way we could fail to NUL-terminate.
Still, strncpy(a,b,sizeof(a)) is an idiom that we ought to squash
everyplace.
Fixes CID #427.
Using strncpy meant that if listenaddress were ever >=
sizeof(sockaddr_un.sun_path), we would fail to nul-terminate
sun_path. This isn't a big deal: we never read sun_path, and the
kernel is smart enough to reject the sockaddr_un if it isn't
nul-terminated. Nonetheless, it's a dumb failure mode. Instead, we
should reject addresses that don't fit in sockaddr_un.sun_path.
Coverity found this; it's CID 428. Bugfix on 0.2.0.3-alpha.
When we rejected a descriptor for not being the one we wanted, we
were letting the parsed descriptor go out of scope.
Found by Coverity; CID # 30.
Bugfix on 0.2.1.26.
(No changes file yet, since this is not in any 0.2.1.x release.)
I'm not one to insist on C's miserly stack limits, but allocating a
256K array on the stack is too much even for me.
Bugfix on 0.2.1.7-alpha. Found by coverity. Fixes CID # 450.
Every node_t has either a routerinfo_t or a routerstatus_t, so every
node_t *should* have a nickname. Nonetheless, let's make sure in
hex_digest_nickname_matches().
Should quiet CID 434.
This is a little error-prone when the local has a different type
from the parameter, and is very error-prone with both have the same
type. Let's not do this.
Fixes CID #437,438,439,440,441.
For some inexplicable reason, Coverity departs from its usual
standards of avoiding false positives here, and warns about all
sscanf usage, even when the formatting strings are totally safe.
Addresses CID # 447, 446.
