Add a specific error to report that a netlink response had
NLM_F_DUMP_INTR set, indicating that the set of results may be
incomplete or inconsistent.
unix.EINTR was previously returned (with no results) when the
NLM_F_DUMP_INTR flag was set. Now, errors.Is(err, unix.EINTR) will
still work. But, this will be a breaking change for any code that's
checking for equality with unix.EINTR.
Return results with ErrDumpInterrupted. Results may be incomplete
or inconsistent, but give the caller the option of using them.
Look for NLM_F_DUMP_INTR in more places:
- linkSubscribeAt, neighSubscribeAt, routeSubscribeAt
- can do an initial dump, which may report inconsistent results
-> if there's an error callback, call it with ErrDumpInterrupted
- socketDiagXDPExecutor
- makes an NLM_F_DUMP request, without using Execute()
-> give it the same behaviour as functions that do use Execute()

They were implemented using SO_SNDTIMEO/SO_RCVTIMEO on the
socket descriptor - but that doesn't work now the socket is
non-blocking. Instead, set deadlines on the file read/write.

Commit c96b03b4be changed the signature
of this method to accept a list of filters and renamed it to
ConntrackDeleteFilters (plural).
This patch
- adds back ConntrackDeleteFilter as an alias
- marks it as deprecated in favor of the new version.
- adds missing stubs for other platforms

ConntrackDeleteFilters enables users to delete flow entries
that match any of the specified filters. This allows users
to delete multiple flow entries with a single dump table call.

Function `LinkDeserialize` checked for presence of `IFF_PROMISC` in
the link's flags to determine whether it was in promiscuous mode.
This flag only tracks what is set with commands such as
ip set <link> promisc on
but is not set when you run `tcpdump` or `wireshark` for example,
which also put the device in promiscuous mode.
There is a counter that tracks the number of times promiscuous mode
has been requested. It reacts to all the ways, `ip set`, and also
`tcpdump` and co.
With this change this counter is used instead of checking the flag.
This makes the library reflect what
ip -d link show <link>
would show in its `promiscuity` field.
To test this change, start some processes of `tcpdump` or similar
and see the counter increase in `ip -d link show <link>` as well
as in the patched version of this netlink library. With the
unpatched version the counter remains 0. Then enable promiscuous
mode globally for the interface. This will increase the count in
all variants, `ip link`, the old unpatched and the patched version
of this netlink library.
Simple test program for reference:
package main
import "fmt"
import "github.com/vishvananda/netlink"
func main() {
handle, _ := netlink.NewHandle()
links, _ := handle.LinkList()
for _, link := range links {
attrs := link.Attrs()
fmt.Printf("dev=%v promisc=%v\n",
attrs.Name, attrs.Promisc)
}
}
The maximum value for an `int` type on a 32-bit platform is 0x7FFFFFFF. Since 0xF0000000 exceeds this limit, we need to use `uint` instead of `int` to handle these values.
- Also refactored setUpNetlinkTestWithKModule function to reduce redundant NS's created and checks made.
- Add conntrack protoinfo TCP support + groundwork for other protocols.
- Tests to cover the above.
- Extend Htb struct in qdisc.go to include DirectQlen field
- Implement the DirectQlen option in qdisc_linux.go
- Modify TestHtbAddDel test to validate DirectQlen changes
Use a tagged version of the dependency. I picked the current version,
although older versions could probably work.

Linux added a new bond transmit hashing policy, VLAN_SRCMAC in [1],
available since Linux 5.12. Add this hashing policy into the respective
data structures.

- `Rate64` field added to the `Netem` struct in `qdisc.go`
- Implemented serialization and deserialization methods for `Rate64`
- Modify `TestClassAddDel` test to validate Rate64 changes
Linux 5.6 and higher support IFLA_PERM_ADDRESS, which contains the
permanent hardware address of the interface if an interface has such an
address. This can be used to identify interfaces even when the normal
hardware address has been changed.

qdisc statistics is exposed in netlink response but not parsed, here we
parse it and expose it via struct QdiscStatistics.
