Backport of #4549. Note that
github.com/cyphar/[email protected]
includes a dependency update ofgolang.org/x/[email protected]
which I've split into a separate commit.This fixes a regression in use of securejoin.MkdirAll, where multiple
runc processes racing to create the same mountpoint in a shared rootfs
would result in spurious EEXIST errors. In particular, this regression
caused issues with BuildKit.
Fixes: dd827f7 ("utils: switch to securejoin.MkdirAllHandle")
Fixes #4543
