resolved: rework CNAME logic a bit more
When following CNAME/DNAME redirects in the stub we currently first
iterate through the packet and pick up what we can use (in
dns_stub_collect_answer_by_question() and friends), following all
CNAMEs/DNAMEs, and would then issue dns_query_process_cname() to move
the DnsQuery object forward too, where we'd then possibly restart
the query and pick things up again, as above.
There's one thought error in this though: dns_query_process_cname()
tries to be smart and will internally follow not just a single
CNAME/DNAME redirect, but a chain of them if they are contained inside
the same packet until we reach the point where the answer is not
included in the packet anymore, where we'd restart the query. This was
great as long as we only focussed on the D-Bus and Varlink resolver
APIs, since there the CNAME/DNAME chain in the middle doesn't actually
matter, we just return information about the final name of the RR and
its content, and aren't interested in the chain to it. For the DNS stub
this is different however: there we need to place the full CNAME/DNAME
chain (and all the appropriate metadata RRs) in the stub reply.
Hence rework this so that we build on the fact that the previous commit
split dns_query_process_cname() in two:
1. dns_query_process_cname_one() will do exactly one CNAME/DNAME
redirect step. This will be called by the stub, so that we can pick
up matching RRs for every single step along the way.
2. dns_query_process_cname_many() will follow a chain as long as that's
possible within the same packet. It's thus pretty much identical to
the old dns_query_process_cname() call. This is what we now use in
the D-Bus and Varlink APIs. dns_query_process_cname_many() is
basically just a loop around dns_query_process_cname_one().
Any logic to follow and pick up RRs manually in the stub along the
CNAME/DNAME path is now dropped (i.e.
dns_stub_collect_answer_by_question() becomes trivially simple again),
we solely rely on dns_query_process_cname_one() to follow CNAME/DNAME
now: each step followed by a full call of dns_stub_assign_sections() to
copy out the RRs that matter.
Net result: things are a bit simpler again, as the only place we follow
CNAME/DNAME redirects is DnsQuery again, and stub answers are always
complete: they contain all CNAME/DNAME RRs on the way including all
their metadata we might pick up in the other sections.
Lennart Poettering [Thu, 25 Mar 2021 10:43:52 +0000 (11:43 +0100)]
resolved: split dns_query_process_cname() into two separate functions
This does some refactoring: the dns_query_process_cname() function
becomes two: dns_query_process_cname_one() and
dns_query_process_cname_many(). The former will process exactly one
CNAME chain element, the latter will follow a chain for as long as
possible within the current packet.
dns_query_process_cname_many() is mostly identical to the old
dns_query_process_cname(), and all existing code is moved over to using
that.
This is mostly preparation for the next commit, where we make direct use
of dns_query_process_cname_one().
This also renames the DNS_QUERY_RESTARTED return value to
DNS_QUERY_CNAME. That's because in the dns_query_process_cname_many()
case as before if we return this we restarted the query in case we
reached the end of the chain without a conclusive answer, as before. But
in dns_query_process_cname_one() we'll only go one step anyway, and
leave restarting if needed to the caller. Hence DNS_QUERY_RESTARTED is a
bit of a misnomer in that case.
This also gets rid of the weird tail recursion in
dns_query_process_cname() and replaces it with an explicit loop in
dns_query_process_cname_many(). The old recursion wasn't a security
issue since we put a limit on the number of CNAMEs we follow anyway, but
it's still icky to scale stack use by that.

resolved: pass mDNS reply packets to each transaction exactly once
Previously we'd iterate through the RRs of an mDNS reply and then find
exactly one matching transaction on our scope for it, and pass it as
reply to that. If multiple RRs of the same packet match we'd pas the
packet multiple times to the transaction even.
This all doesn't really work anymore since there can be multiple open
transactions for the same key (with different flags), and it's kinda
ugly anywy. Hence let's turn this around: let's iterate through the
transactions and check if any of the included RRs match it, and if so
pass the packet to that transaction exactly once.
This speeds up mDNS a bit, since previously we'd oftentimes fail to find
all suitable transactions for an mDNS reply (because there can be
multiple transactions for the same RR key with different flags, and we
checked exactly one flag combination). Which would then mean the
transaction would time out, and be retried – at which point the cache
would be populated and thus it would still succeed, but only after this
timeout. With this fix this is corrected: every transaction that matches
will get the reply, instantly as we get it.

sd-event: disable epoll_pwait2 for now
This reverts the gist of commit
798445ab84cff51bde7fcf936f0fb19c37cf858c.
Unfortunately the new syscall causes test-event to hang. 32 bit architectures
seem affected: i686 and arm32 in fedora koji. 32 bit build of test-event hangs
reliably under valgrind:
$ PKG_CONFIG_LIBDIR=/usr/lib/pkgconfig meson build-32 -Dc_args=-m32 -Dc_link_args=-m32 -Dcpp_args=-m32 -Dcpp_link_args=-m32 && ninja -C build-32 test-event && valgrind build/test-event
If I set epoll_pwait2_absent=true, so the new function is never called, then
the issue does not reproduce. It seems to be strictly tied to the syscall.
On amd64, the syscall is not used, at least with the kernel that Fedora
provides. The kernel patch
58169a52ebc9a733aeb5bea857bc5daa71a301bb says:
For timespec, only support this new interface on 2038 aware platforms
that define __kernel_timespec_t. So no CONFIG_COMPAT_32BIT_TIME.
And Fedora sets CONFIG_COMPAT_32BIT_TIME=y. I expect most other distros will too.
On amd64: epoll_wait_usec: epoll_pwait2: ret=-1 / errno=38
On i686 (same kernel): epoll_wait_usec: epoll_pwait2: ret=2 / errno=0
Is this some kind of emulation? Anyway, it seems that this is what is going wrong.
So let's disable the syscall until it becomes more widely available and the
kinks have been ironed out.

When immediately calling exec in the child, prefer to explicitly reopen the log
after exec fails. In other cases, just use FORK_REOPEN_LOG.

log: protect errno in log_open()
Commit
0b1f3c768ce1bd1490a5e53f539976dcef8ca765 has introduced log_open()
calls after exec fails post-fork. However, the log_open() call itself could
change the value of errno, which, for me, manifested in:
$ coredumpctl gdb
...
Failed to invoke gdb: Success
Fix this by using PROTECT_ERRNO in log_open().

shared/calendarspec: abort calculation after 1000 iterations
We have a bug where we seem to enter an infinite loop when running in the
Europe/Dublin timezone. The timezone is "special" because it has negative SAVE
values. The handling of this should obviously be fixed, but let's use a
belt-and-suspenders approach, and gracefully fail if we fail to find an answer
within a specific number of attempts. The code in this function is rather
complex, and it's hard to rule out another bug in the future.

repart: make sure to grow partition table after growing backing loopback file
This fixes the --size= switch, i.e. where we grow a disk image: after
growing it we need to expand the partition table so that its idea of the

calculations in the subsequent steps might still use the original
ungrown size.
