a17537a238 Fix an fd leak in check_private_dir().
The fd would leak when the User wasn't recogniezed by
getpwnam(). Since we'd then go on to exit, this wasn't a terribad
leak, but it's still not as nice as no leak at all.

CID 1355640; bugfix on no released Tor.

580e549f75 remove extraneous breaks
commit edeba3d4 removed a switch, but left the "break" lines in
from that switch. fortunately the resulting behavior was not wrong,
since there was an outer switch that it was ok to break from.

4861e24552 fix indentation after #18332 patches
no actual changes here -- but the new indenting makes it clear
that the fixes in #18332 were not as good as they should have been.
the next commit will deal with that.

b24f15a9a1 In routers_make_ed_keys_unique, break ties for published_on
This ensures that if we can't use published_on to decide an ed,rsa
mapping, we at least decide deterministically.

48f8229504 After we strip out duplicate entries from 'routers', don't use 'rl'.
We've got to make sure that every single subsequent calculation in
dirserv_generate_networkstatus_vote_obj() are based on the list of
routerinfo_t *after* we've removed possible duplicates, not before.
Fortunately, none of the functions that were taking a routerlist_t
as an argument were actually using any fields other than this list
of routers.

Resolves issue 18318.DG3.

fa07c60c67 Fix another case of 17668: Add NoEdConsensus
I had a half-built mechanism to track, during the voting process,
whether the Ed25519 value (or lack thereof) reflected a true
consensus among the authorities.  But we never actually inserted this
field in the consensus.

The key idea here is that we first attempt to match up votes by pairs
of <Ed,RSA>, where <Ed> can be NULL if we're told that there is no
Ed key.  If this succeeds, then we can treat all those votes as 'a
consensus for Ed'.  And we can include all other votes with a
matching RSA key and no statement about Ed keys as being "also about
the same relay."

After that, we look for RSA keys we haven't actually found an entry
for yet, and see if there are enough votes for them, NOT considering
Ed keys.  If there are, we match them as before, but we treat them
as "not a consensus about ed".

When we include an entry in a consensus, if it does not reflect a
consensus about ed keys, then we include a new NoEdConsensus flag on
it.

This is all only for consensus method 22 or later.

Also see corresponding dir-spec patch.

13a31e72db Never vote for an ed key twice.
When generating a vote, and we have two routerinfos with the same ed
key, omit the one published earlier.

This was supposed to have been solved by key pinning, but when I
made key pinning optional, I didn't realize that this would jump up
and bite us.  It is part of bug 18318, and the root cause of 17668.

it is a vote or a consensus.

dd7c999617 Make unix sockets work with the linux seccomp2 sandbox again
I didn't want to grant blanket permissions for chmod() and chown(),
so here's what I had to do:
   * Grant open() on all parent directories of a unix socket
   * Write code to allow chmod() and chown() on a given file only.
   * Grant chmod() and chown() on the unix socket.

permissions.

Found by coverity. Not in any released Tor. Fixes CID 1355640.

Also, don't check for fd correctness with assert(fd).  You need to

d8b93b31a0 hs: Do not close desc fetch conn. if we can't pick an HSDir
Launching 7 descriptor fetches makes a connection to each HSDir that is 6
and the seventh one fails to pick an HSDir because they are all being used
already so it was killing all pending connections at once.
