Let's use the new flag wherever we read key material/passphrases/hashes
off disk, so that people can plug in their own IPC service as backend if
they like, easily.
(My main goal was actually to support this for crypttab key files — i.e.
that you can specify AF_UNIX sockets as third column in crypttab — but
that's harder to implement, since the keys are read via libcryptsetup's
API, not ours.)
We would say "ignoring", but invalidate the peer anyway.
Let's only do that if we modified the peer irreperably.
Also add comments explaining allocation handling.
Patch contains a coccinelle script, but it only works in some cases. Many
parts were converted by hand.
Note: I did not fix errors in return value handing. This will be done separate
to keep the patch comprehensible. No functional change is intended in this
patch.
let's add [static] where it was missing so far
Drop [static] on parameters that can be NULL.
Add an assert() around parameters that have [static] and can't be NULL
hence.
Add some "const" where it was forgotten.
When compiled with -DNDEBUG, we get warnings about set-but-unused variables.
In general, it's not something we care about, but since removing those
variables arguably makes the code nicer, let's just to it in this case.
c4397d94c3 introduces
link_detach_from_manager() and netdev_detach_from_manager(), and they
set Link::manager or NetDev::manager NULL.
But, at the time e.g. link is removed, hence link_drop() is called,
there may be still some asynchronous netlink call is waiting, and
their callbacks hit assertion.
This make {link,netdev}_detach_from_manager() just drop all references
from manager, but keep the pointer to manager.
Fixes#11411.
This is actually a u16, not a u32, so the kernel complains:
kernel: netlink: 'systemd-network': attribute type 5 has an invalid length
This is due to:
if (nla_attr_len[pt->type] && attrlen != nla_attr_len[pt->type]) {
pr_warn_ratelimited("netlink: '%s': attribute type %d has an invalid length.\n",
current->comm, type);
}
Presumably this has been working fine in functionality on little-endian
systems, but nobody bothered to try on big-endian systems.
