[Linuxptp-devel] [PATCH 0/3] Store and config clock description

[Geoff Salmon]

This patch set adds a clock_description struct to the clock which
holds some of the data needed for the CLOCK_DESCRIPTION management
message. There's also a patch for configuring the description.

You'll see the first patch adds a StaticPTPText struct that includes
storage space for the string. This avoids any dynamic memory
allocation and simplifies setting the string value. There will only
ever be a handful of StaticPTPStructs, so the wasted memory won't
exceed a couple kilobytes.

StaticPTPText's can also enforce symbol length restrictions and I've
added strlen_utf8 in util.c to determine the symbol length of utf8
strings. However, it won't detect invalid utf8 or account for
combining characters. Dealing with how to count combining characters
is a rabbit hole we probably don't want to go down, but detecting
invalid utf8 data may be a good idea in the future, especially when
the user description can be set remotely using a management message.
