TL;DR: Three ZFS tests created ZFS pools on all unmounted devices listed
in /etc/fstab, corrupting their contents. Stop that.
Imagine my surprise when the ESP on my main dev/test VM would "randomly"
become corrupted, making it unbootable. Three tests collect various devices
from the system and try to add them to a test pool. The test expects this
to fail because it _assumes_ these devices are in use and ZFS will correctly
reject the request.
My /etc/fstab has two entries for devices in /dev:
/dev/gpt/swap0 none swap sw,trimonce,late
/dev/gpt/esp0 /boot/efi msdosfs rw,noauto
Note the `noauto` on the ESP. In a remarkable example of irony, I chose
this because it should keep the ESP more protected from corruption;
in fact, mounting it would have protected it from this case.
The tests added all of these devices to a test pool in a _single command_,
expecting the command to fail. The swap device was in use, so the command
correctly failed, but the ESP was added and therefore corrupted. However,
since the command correctly failed, the test didn't notice the ESP problem.
If each device had been added with its own command, the test _might_ have
noticed that one of them incorrectly succeeded. However, two of these
tests would not have noticed:
hotspare_create_001_neg was incorrectly specified as needing the Solaris
dumpadm command, so it was skipped. _Some_ of the test needs that command,
but it checks for its presence and runs fine without it.
Due to bug 241070, zpool_add_005_pos was marked as an expected failure.
Due to the coarse level of integration with ATF, this test would still
"pass" even if it failed for the wrong reason. I wrote bug 267554 to
reconsider the use of atf_expect_fail in these tests.
Let's further consider the use of various devices found around the system.
In addition to devices in /etc/fstab, the tests also used mounted devices
listed by the `mount` command. If ZFS behaves correctly, it will refuse
to added mounted devices and swap devices to a pool. However, these are
unit tests used by developers to ensure that ZFS still works after they
modify it, so it's reasonable to expect ZFS to do the _wrong_ thing
sometimes. Using random host devices is unsafe.
Fix the root problem by using only the disks provided via the "disks"
variable in kyua.conf. Use one to create a UFS file system and mount it.
Use another as a swap device. Use a third as a dump device, but expect
it to fail due to bug 241070.
While I'm here:
Due to commit 6b6e2954dd, we can simply add a second dump device and
remove it in cleanup. We no longer need to save, replace, and restore the
pre-existing dump device.
The cleanup_devices function used `camcontrol inquiry` to distinguish disks
from other devices, such as partitions. That works fine for SCSI, but not
for ATA or VirtIO block. Use `geom disk list` instead.

Rather than using a Scapy-based Python script only check if the state

lists all interfaces and gets their (IPv6) addresses a couple of times
at startup. This can be sufficient for the ICMP state to time out and
the test to fail.

The test was failing due to the assert on lack of MSG_TRUNC flag in the
output flags of recvmsg().
The code passed MSG_TRUNC, along with sufficient-size buffer to hold the
message to-be-received to the recvmsg(), and expected MSG_TRUNC to be
returned as well.
This is not exactly correct as a) MSG_TRUNC was not even a supported
recvmsg() flag before be1f485d7d and b) it violates POSIX, as
POSIX states it should be set only "If a message is too long to fit in
the supplied buffers,".
The test was working before as the kernel copied input flags to the
output flags. be1f485d7d changed that behaviour to clear MSG_TRUNC
if it was present on the input.
Fix the test by checking POSIX-defined behaviour.
Discussed with: glebius
Implement Linux-variant of MSG_TRUNC input flag used in recv(), recvfrom() and recvmsg().
Posix defines MSG_TRUNC as an output flag, indicating packet/datagram truncation.
Linux extended it a while (~15+ years) ago to act as input flag,
resulting in returning the full packet size regarless of the input
buffer size.
It's a (relatively) popular pattern to do recvmsg( MSG_PEEK | MSG_TRUNC) to get the
packet size, allocate the buffer and issue another call to fetch the packet.
In particular, it's popular in userland netlink code, which is the primary driving factor of this change.
This commit implements the MSG_TRUNC support for SOCK_DGRAM sockets (udp, unix and all soreceive_generic() users).

Currently, processing of IPv6 local traffic is partially broken:
link-local connection fails and global unicast connect() takes
3 seconds to complete.
This happens due to the combination of multiple factors.
IPv6 code passes original interface "origifp" when passing
traffic via loopack to retain the scope that is mandatory for the
correct hadling of link-local traffic. First problem is that the logic
of passing source interface is not working correcly for TCP connections,
resulting in passing "origifp" on the first 2 connection attempts and
lo0 on the subsequent ones. Second problem is that source address
validation logic skips its checks iff the source interface is loopback,
which doesn't cover "origifp" case.
More detailed description is available at https://reviews.freebsd.org/D35732
Fix the first problem by untangling&simplifying ifp/origifp logic.
Fix the second problem by switching source address validation check to
using M_LOOP mbuf flag instead of interface type.

Currently selectroute() contains two nearly-identical versions of
the route lookup logic - one for original destination and another
for the case when IPV6_NEXTHOP option was set on the socket.
Factor out handling these route lookups in a separation function to
improve readability.
This change also fixes handling of link-local IPV6_NEXTHOPs.

Notable amount of tests related to the packet IO require two VNET jails
for proper testing and avoiding side effects for the host system.
Additionally, it is often required to run actions in the jails seme-sequentially
- waiting for the listener initialisation can be an example of such
dependency.
This change extends pytest vnet framework to allow defining multi-vnet
multi-epair topologies in declarative style, without any need to bother
about jail or repair names. All jail creation/teardown, interface
creation/teardown and address assignments are handled automatically.
Example:
TOPOLOGY = {
"vnet1": {"ifaces": ["if1", "if2", "if3"]},
"vnet2": {"ifaces": ["if1", "if2", "if3"]},
"if1": {"prefixes6": [("2001:db8:a::1/64", "2001:db8:a::2/64")]},
"if2": {"prefixes6": [("2001:db8:b::1/64", "2001:db8:b::2/64")]},
"if3": {"prefixes6": [("2001:db8:c::1/64", "2001:db8:c::2/64")]},
}
def vnet2_handler(self, vnet, obj_map, pipe):
ss = VerboseSocketServer("::", self.DEFAULT_PORT)
pipe.send("READY")
def test_output6_base(self):
self.wait_object(second_vnet.pipe)
The definitions above will create 2 vnets ("jail_test_output6_base",
"jail_test_output6_base_2"), 3 epairs, attached to both first and
second jails, set up the IP addresses for each epair, spawn another
process for vnet2_handler and pass control to vnet2_handler and
test_output6_base. Both processes can pass objects between each
other using pre-created pipes.

If we receive a UDP packet (directed towards an active OpenVPN socket)
which is too short to contain an OpenVPN header ('struct
ovpn_wire_header') we wound up making m_copydata() read outside the
mbuf, and panicking the machine.
Explicitly check that the packet is long enough to copy the data we're
interested in. If it's not we will pass the packet to userspace, just
like we'd do for an unknown peer.
Extend a test case to provoke this situation.

Do not panic if we try to dummynet an Ethernet packet that's not IPv4 or
IPv6. Simply give it to dummynet.

OpenVPN uses IPv4-mapped IPv6 addresses by default (if we don't specify
'proto udp4', or an IPv4 address to bind to). Test that this works.

Instead of returning EMSGSIZE pass the error code from fdallocn() directly
to userland. That would be EMFILE, which makes much more sense. This
error code is not listed in the specification[1], but the specification
doesn't cover such edge case at all. Meanwhile the specification lists
EMSGSIZE as the error code for invalid value of msg_iovlen, and FreeBSD
follows that, see sys_recmsg(). Differentiating these two cases will make
a developer/admin life much easier when debugging.

This change is a continuation of 9c42645a1e workaround.
Apparently pytest argument parser is not happy when parsing values
with spaces or just more than one --atf-var argument.
Switch wrapper to send these kv pairs as env variables. Specifically,
use _ATF_VAR_key=value format to distinguish from the other vars.
Add the `atf_vars` fixture returning all passed kv pairs as a dict.

OpenVPN allows us to push routes for client networks with the 'iroute'
