This implements a feature from bug 13000. Instead of starting a bwauth
run with this wrong idea about their bw, relays should do the self-test
and then get measured.
When a tor relay starts up and has no historical information about its
bandwidth capability, it uploads a descriptor with a bw estimate of 0.
It then starts its bw selftest, but has to wait 20 minutes to upload the
next descriptor due to the MAX_BANDWIDTH_CHANGE_FREQ delay. This change
should mean that on average, relays start seeing meaningful traffic a
little quicker, since they will have a higher chance to appear in the
consensus with a nonzero bw.
Patch by Roger, changes file and comment by Sebastian.
We're calling mallocfn() and reallocfn() in the HT_GENERATE macro
with the result of a product. But that makes any sane analyzer
worry about overflow.
This patch keeps HT_GENERATE having its old semantics, since we
aren't the only project using ht.h. Instead, define a HT_GENERATE2
that takes a reallocarrayfn.
Most of these are in somewhat non-obvious code where it is probably
a good idea to initialize variables and add extra assertions anyway.
Closes 13036. Patches from "teor".
This commit attempts to satisfy nickm's comment on check_private_dir() permissions:
https://trac.torproject.org/projects/tor/ticket/11291#comment:12
"""check_private_dir() ensures that the directory has bits 0700 if CPD_CHECK_MODE_ONLY is not set. Shouldn't it also ensure that the directory has bits 0050 if CPD_CHECK_MODE_ONLY is not set, and CPD_GROUP_READ is set?"""
It's now a protocol-warn, since there's nothing relay operators can
do about a client that sends them a malformed create cell.
Resolves bug 12996; bugfix on 0.0.6rc1.
Any error when acquiring the CryptoAPI context should get treated as
bad. Also, this one can't happen for the arguments we're giving.
Fixes bug 10816; bugfix on 0.0.2pre26.
Previously, we had done this only in the connection_free() case, but
when we called connection_free_() directly from
connections_free_all(), we didn't free the connections.
The fix for bug 4647 accidentally removed our hack from bug 586 that
rewrote HashedControlPassword to __HashedControlSessionPassword when
it appears on the commandline (which allowed the user to set her own
HashedControlPassword in the torrc file while the controller generates
a fresh session password for each run).
Fixes bug 12948; bugfix on 0.2.5.1-alpha.
This way, we don't get locking failures when we hit an assertion in
the unit tests. Also, we might find out about unit test bugs from
folks who can't do gdb.
The rest of the filesystem is accessible for reading only. Still, quoting
systemd.exec(5):
Note that restricting access with these options does not extend to submounts
of a directory that are created later on.
