(Second part of a bug8367 fix. -NM)
|
|
This fixes bug 8367, introduced in d7089ff228227259137b5a8b. Not in
any released Tor.
|
|
|
|
We don't use subversion or src/*/makefile.am any longer
|
|
|
|
|
|
This should prevent crashes on further recurrence of 8065, and help
diagnose such if they occur

Unmeasured=1 issue
|
|
This patch moves the measured_bw field and the has_measured_bw field
into vote_routerstatus_t, since only votes have 'Measured=XX' set on
their weight line.
I also added a new bw_is_unmeasured flag to routerstatus_t to
represent the Unmeasured=1 flag on a w line. Previously, I was using
has_measured_bw for this, which was quite incorrect: has_measured_bw
means that the measured_bw field is set, and it's probably a mistake
to have it serve double duty as meaning that 'baandwidth' represents a
measured value.
While making this change,I also found a harmless but stupid bug in
dirserv_read_measured_bandwidths: It assumes that it's getting a
smartlist of routerstatus_t, when really it's getting a smartlist of
vote_routerstatus_t. C's struct layout rules mean that we could never
actually get an error because of that, but it's still quite incorrect.
I fixed that, and in the process needed to add two more sorting and
searching helpers.
Finally, I made the Unmeasured=1 flag get parsed. We don't use it for
anything yet, but someday we might.
This isn't complete yet -- the new 2286 unit test doesn't build.

Instead of capping whenever a router has fewer than 3 measurements,
we cap whenever a router has fewer than 3 measurements *AND* there
are at least 3 authorities publishing measured bandwidths.
We also generate bandwidth lines with a new "Unmeasured=1" flag,
meaning that we didn't have enough observations for a node to use
measured bandwidth values in the authority's input, whether we capped
it or not.

Avoid the phrase "legally valid" (as opposed to valid but not legal)?
And document what functions really do.
Fix for bug 6935.

Apparently there is a compiler that believes this is something to
warn about.

Stop marking every relay as having been down for one hour every
time we restart a directory authority. These artificial downtimes
were messing with our Stable and Guard flag calculations.
Fixes bug 8218 (introduced by the fix for 1035). Bugfix on 0.2.2.23-alpha.

This will get it building on systems that lack stdint.h

We shouldn't be calling choose_random_entry() for directory
conncetions; that's what choose_random_dirguard() is for.

and replace it with the good old-fashioned two functions approach
|
|
now that both timers are on the same schedule, there's no point
tracking separate timers.

Relays used to check every 10 to 60 seconds, as an accidental side effect
of calling directory_fetches_from_authorities() when considering doing
a directory fetch. The fix for bug 1992 removes that side effect. At the
same time, bridge relays never had the side effect, leading to confused
bridge operators who tried crazy tricks to get their bridges to notice
IP address changes (see ticket 1913).
The new behavior is to reinstate an every-60-seconds check for both
public relays and bridge relays, now that the side effect is gone.
|
|
For example, we were doing a resolve every time we think about doing a
directory fetch. Now we reuse the cached answer in some cases.
Fixes bugs 1992 (bugfix on 0.2.0.20-rc) and 2410 (bugfix on
0.1.2.2-alpha).

I didn't make any of the callers use this feature yet.

One is a probably-impossible leak if we fail to sign a consensus;
another occurs when we can't look up the user we're trying to chown
our sockets to.

Coverity is worried about this (CID 980653). It hasn't happened in
testing, but we might as well make sure it can't happen.

When we compute the estimated microseconds we need to handle our
pending onionskins, we could (in principle) overflow a uint32_t if
we ever had 4 million pending onionskins before we had any data
about how onionskins take. Nevertheless, let's compute it properly.
Fixes bug 8210; bugfix on 0.2.4.10. Found by coverity; this is CID
980651.

If geoip_format_bridge_stats() returned NULL when it should have
returned a string, we would have tried to deref NULL, and died. Not
a big deal in the unit tests, but still worth fixing.

This fixes a crash bug if we fail to generate an extrainfo
descriptor.
