When directory authorities read a zero-byte bandwidth file, they log
a warning with the contents of an uninitialised buffer. Log a warning
about the empty file instead.
Fixes bug 26007; bugfix on 0.2.2.1-alpha.
Remove v3 optimization which made Tor not detect disabling services.
This optimization is not so needed because we only call that function after HUP
anyway.
Fixes bug #25761.
During service configuration, rend_service_prune_list_impl_() sets
rend_service_staging_list to NULL, which blocked pruning after a HUP.
This patch initializes rend_service_staging_list when needed, so that HUP can
detect disabled onion services.
Fixes bug #25761.
Previously the coverage on this function was mostly accidental,
coming as it did from test_entryconn.c. These new tests use mocking
to ensure that we actually hit the different failure and retry cases
of addressmap_get_virtual_address(), and make our test coverage a
bit more deterministic.
Closes ticket 25993.
Stop saying in the manual that clients cache ipv4 dns answers from exit
relays. We haven't used them since 0.2.6.3-alpha, and in ticket 24050
we stopped even caching them as of 0.3.2.6-alpha, but we forgot to say
so in the man page.
Fixes bug 26052; bugfix on 0.3.2.6-alpha.
Code movement for the refactoring for ticket 24658 didn't copy the
inclusion of sys/random.h, which is needed to get a prototype for
getentropy() on macOS 10.12 Sierra. It also didn't copy the inclusion
of sys/syscall.h, which might prevent the getrandom() syscall from
being properly detected. Move these inclusions. Bug not in any
released Tor.
Our previous algorithm had a nonzero probability of picking no
events to cancel, which is of course incorrect. The new code uses
Vitter's good old reservoir sampling "algorithm R" from 1985.
Fixes bug 26008; bugfix on 0.2.6.3-alpha.
This functionality was covered only accidentally by our voting-test
code, and as such wasn't actually tested at all. The tests that
called it made its coverage nondeterministic, depending on what time
of day you ran the tests.
Closes ticket 26014.
