I was confused, because both commits (on tftpd and uClibc) are about 7
years old, so I was wondering which you were referring to...

But yes, you were rerferring to the tftpd commit. Which got me wondering
why we needed to apply a patch that have been applied upstream 7 years
ago. Why can't we just bump the version rather than backport patches?

Ah, tftpd hasn't had any new release for the past 10 years now, so *are*
up-to-date...

But then, yes, why can't we just switch to the latest commit in the git
tree, then, rather than backport the fix? Given that tftpd hasn't seen
any commit since 2015, we would not take too big a risk...

Yann E. MORIN.
