6 years agoudev: net_id: Improve predictable names for SR-IOV virtual devices

udev: net_id: Improve predictable names for SR-IOV virtual devices

With PCI SR-IOV, a number of virtual network devices can be enabled,
all of which share the same physical network device.  Currently,
udev generates names for SR-IOV virtual functions as if they were
independent network devices.

With this change, the predictable network device naming code will
check if a network device is an SR-IOV virtual device, and will
generate a name based on the physical PCI device plus a "v%u"
suffix.  This should improve readability and predictability of
device names.

Here is an example of how this change would affect naming:

before patch  |  after patch
-----------------------------
eno1          |  eno1          onboard NIC, physical function
enp101s0f0    |  eno1v0        onboard NIC, SR-IOV virtual func 0
enp101s0f1    |  eno1v1        onboard NIC, SR-IOV virtual func 1

udev: net_id: search parent devices for PCI slot number

To generate predictable network device names, the code in
udev-builting-net_id.c tries to match the PCI device address
of the network device to the entries in /sys/bus/pci/slots.
However, sometimes the slot number is not associated the
network controller PCI device itself, but rather with one of
its parents.

This change will try to find a match in /sys/bus/pci/slots for
the parents of the PCI network device, if it doesn't find a

Partially revert "seccomp: add mmap and address family restrictions for MIPS" (#8563)

This reverts the mmap parts of f5aeac1439d64905c7b1b57042c39589dd31e3a6,
but keeps the part which restricts address families which works
correctly.

Unfortunately the MIPS toolchains still do not implement PT_GNU_STACK.
This means that while the commit to restrict mmap on MIPS was "correct",
it had the side effect of causing pthread_create to fail because glibc tries
to allocate an executable stack for new threads in the absense of
PT_GNU_STACK. We should wait until PT_GNU_STACK is implemented in all

core: delay adding target dependencies until all units are loaded and aliases resolved (#8381)

Currently we add target dependencies while we are loading units. This
can create ordering loops even if configuration doesn't contain any
loop. Take for example following configuration,

$ systemctl get-default
multi-user.target

$ cat /etc/systemd/system/test.service
[Unit]
After=default.target

[Service]
ExecStart=/bin/true

[Install]
WantedBy=multi-user.target

If we encounter such unit file early during manager start-up (e.g. load
queue is dispatched while enumerating devices due to SYSTEMD_WANTS in
udev rules) we would add stub unit default.target and we order it Before
test.service. At the same time we add implicit Before to
multi-user.target. Later we merge two units and we create ordering cycle
in the process.

To fix the issue we will now never add any target dependencies until we
loaded all the unit files and resolved all the aliases.
