Coverity has had trouble figuring out our csiphash implementation,
and has given spurious warnings about its behavior.
This patch changes the csiphash implementation when coverity is in
use, so that coverity can figure out that we are not about to read
beyond the provided input.
Closes ticket 31025.
Coverity doesn't understand that if begin_cell_parse() returns 0 and
sets is_begindir to 0, its address field will always be set.
Fixes bug 30126; bugfix on 0.2.4.7-alpha; Fixes CID 1447296.
Replace the 157 fallbacks originally introduced in Tor 0.3.5.6-rc
in December 2018 (of which ~122 were still functional), with a
list of 148 fallbacks (70 new, 78 existing, 79 removed) generated
in June 2019.
Closes ticket 28795.
Note that we created extra lists from DE and US, but they didn't add
any more fallbacks when we tried to merge them.
When parsing addreses via Tor's internal address:port parsing and
DNS lookup APIs, require IPv6 addresses with ports to have square
brackets.
But allow IPv6 addresses without ports, whether or not they have
square brackets.
Fixes bug 30721; bugfix on 0.2.1.5-alpha.
When parsing addreses via Tor's internal DNS lookup API:
* reject IPv4 addresses in square brackets (with or without a port),
* accept IPv6 addresses in square brackets (with or without a port), and
* accept IPv6 addresses without square brackets, as long as they have no port.
This change completes the work started in 23082, making address parsing
consistent between tor's internal DNS lookup and address parsing APIs.
Fixes bug 30721; bugfix on 0.2.1.5-alpha.
Right now, this has been done at a high level by confparse.c, but it
makes more sense to lower it.
This API is radically un-typesafe as it stands; we'll be wrapping it
in a safer API as we do #30914 and lower the struct manipulation
code as well.
Closes ticket 30864.
If the signature data was removed, but the keyword was kept, this could
result in an unparseable extra info file.
Fixes bug 30958; bugfix on 0.2.7.2-alpha.
Always publish bridge pluggable transport information in the extra info
descriptor, even if ExtraInfoStatistics is 0. This information is
needed by BridgeDB.
Fixes bug 30956; bugfix on 0.4.1.1-alpha.
