More often than not, the created devnode is the basename of the
sysfs entry. The "devnode" device may be used to override the
auto-detected node name.
Permissions and major/minor number are now verified on the devnode
itself, not on symlinks.
For those tests where exp_name is set to the computed devnode name,
the explicit "exp_name" can be removed. "exp_name" is only required for
symlinks.
This allows separate testing for devnodes and symlinks an a follow-up
patch.
Allow testing cases where multiple devices are added and removed
simultaneously. Tests are started as synchronously as possible using a
semaphore, in order to test possible race conditions. If this isn't desired,
the test parameter "sleep_us" can be set to the number of microseconds to wait
between udev invocations.
Allow testing cases where multiple devices are added and removed.
This implies a change of the data structure: every test allows
for multiple devices to be added, and "exp_name" etc. are now properties
of the device, not of the test.
When selinux is enabled, the call of
manager_rtnl_enumerate_nexthop() fails.
This fix is to facilitate selinux hook handling for enumerating
nexthop.
In manager_rtnl_enumerate_nexthop() there is a check
if "Not supported" is returned by the send_netlink() call.
This check expects that -EOPNOTSUPP is returned,
the selinux hook seems to return -EINVAL instead.
This happens in kernel older than 5.3
(more specificallytorvalds/linux@65ee00a) as it does not support
nexthop handling through netlink.
And if SELinux is enforced in the order kernel, callingRTM_GETNEXTHOP
returns -EINVAL.
Thus adding a call in the manager_rtnl_enumerate_nexthop for the
extra return -EINVAL.
* Existing valid rule files written with KEY="value" are not affected
* Now, KEY=e"value\n" becomes valid. Where `\n` is a newline character
* Escape sequences supported by src/basic/escape.h:cunescape() is
supported
With these patches applied, networkd is successfully able to get an
address from a DHCP server on an IPoIB interface.
1)
Makes networkd pass the actual interface type to the dhcp client,
instead of hardcoding it to Ethernet.
2)
Fixes some issues in handling the larger (20 Byte) IB MAC addresses in
the dhcp code.
3)
Add a new field to networkds Link struct, which holds the interface
broadcast address.
3.1)
Modify the DHCP code to also expect the broadcast address as parameter.
On an Ethernet-Interface the Broadcast address never changes and is always
all 6 bytes set to 0xFF.
On an IB one however it is not neccesarily always the same, thus
fetching the actual address from the interface is neccesary.
4)
Only the last 8 bytes of an IB MAC are stable, so when using an IB MAC to
generate a client ID, only pass those 8 bytes.
This passes the legacy ethernet address to functions in a lot of places,
which all will need migrated to handle arbitrary size hardware addresses
eventually.
Hardware addresses come in various shapes and sizes, these new functions
and accomapying data structures account for that instead of hard-coding
a hardware address to the 6 bytes of an ethernet MAC.
Ideally, we'd read back what we wrote, but that would have been
much more complicated. But just writing stuff is useful to test under
valgrind or manually.
We had two of each: both homectl and journalctl had the whole dlopen()
wrapper, and journalctl had two implementations (slightly different) of the
code to print the fss:// pattern.
print_qrcode() now returns -EOPNOTSUPP when compiled with qrcode support. Both
callers ignore the return value, so this changes nothing.
No functional change.
To make things simple and robust when debugging journald, we'll leave
the SO_TIMESTAMP invocations in the C code in place, even if they are
now typically redundant, given that the sockets are already passed into
the process with SO_TIMESTAMP turned on now.
This adds a way to control SO_TIMESTAMP/SO_TIMESTAMPNS socket options
for sockets PID 1 binds to.
This is useful in journald so that we get proper timestamps even for
ingress log messages that are submitted before journald is running.
We recently turned on packet info metadata from PID 1 for these sockets,
but the timestamping info was still missing. Let's correct that.
Let's not have #ifdeffery both in the consumers and the providers of the
selinux glue code. Unless the code is particularly complex, let's do the
ifdeffery only in the provider of the selinux glue code, and let's keep
the consumers simple and just invoke it.
