while theoretically a nice interface, qsort_r on GLIBC was
implemented with a prototype that shuffles the argument order
around when compared to the traditional BSD implementations,
yielding in 2 separate incompatible implementations.
even worse, the arguments are all of pointer type so one would
not even notice that the order is wrong and so this would yield
in crashes or silent memory corruption.
thus musl does not implement it, because configure scripts would
check for its existance and use it unconditionally, even when
assuming the BSD version.
a more portable solution is to use TLS via __thread, which any
modern GCC should provide. (even 3.4.6 on x86/x86_64 does so).

this is a glibc specific alias for realpath(path, NULL).
to be portable, we need to use the real thing which is even less
verbose.

Note: udev_builtin_net_setup_link has *not* been imported. Also
still missing from udev-builtin is udev_builtin_uaccess.

This matches the bcma support in the network device naming.
Eventually wa want to make sure ID_PATH is equivalent to ID_NET_NAME_PATH,
so we never need to match on the latter.

Since the invention of read-only memory, write-only memory has been
considered deprecated. Where appropriate, either make use of the
value, or avoid writing it, to make it clear that it is not used.

Uevents are events of the host, which should not leak into a container.
Containers do not support hotplug at the moment, and devices and uevents
are not namespace aware.

Clang is a bit more strict wrt format-nonliterals:
http://clang.llvm.org/docs/LanguageExtensions.html#format-string-checking
Adding these extra printf attributes also makes gcc able to find more
problems. E.g. this patch uncovers a format issue in udev-builtin-path_id.c
Some parts looked intetional about breaking the format-nonliteral check.
I added some supression for warnings there.

Returning anything else but NULL would suggest the caller's reference
might still be valid, but it isn't, because the caller just invoked
_unref() after all.
This turns the return value into a typesafe shortcut that allows
unreffing and resetting a reference in one line. In contrast to
solutions for this which take a pointer to a pointer to accomplish the
same this solution is just syntactic sugar the developer can make use of
but doesn't have to, and this is particularly useful when immediately
unreffing objects returned by function calls.

In the process, rename udev_encode_string which is poorly named
for what it does. It deals specifically with encoding names that
udev creates and has its own rules: utf8 is valid but some ascii
is not (e.g. path separators), and everything else is simply escaped.
Rename it to encode_devnode_name.

There's now some more obvious overlap amongst the two
utf8 validation functions, but no more than there already
was previously. This also adds some menial tests for anyone
who wants to do more merging of these two in the future.

Handle -1 return from sysconf(_SC_GET{PW,GR}_R_SIZE_MAX)
|
|
POSIX says:
Note that sysconf(_SC_GETGR_R_SIZE_MAX) may return -1 if there is no
hard limit on the size of the buffer needed to store all the groups
returned.
The example from POSIX uses a default buffer size of 1024 in that case.
