By allowing Open(at)InRoot to opt-out of the extra work done by MkdirAll
to do the necessary "partial lookups", Open(at)InRoot now does less work
for both implementations (resulting in a many-fold decrease in the number of
operations for openat2, and a modest improvement for non-openat2) and is
far more guaranteed to match the correct openat2(RESOLVE_IN_ROOT)
behaviour.
We now use readlinkat(fd, "") where possible. For Open(at)InRoot this
effectively just means that we no longer risk getting spurious errors during
rename races. However, for our hardened procfs handler, this in theory should
prevent mount attacks from tricking us when doing magic-link readlinks (even
when using the unsafe host /proc handle). Unfortunately Reopen is still
potentially vulnerable to those kinds of somewhat-esoteric attacks.
Several improvements were made to the errors returned by Open(at)InRoot and
MkdirAll when dealing with invalid paths under the emulated (ie.
non-openat2) implementation. Previously, some paths would return the wrong
error (ENOENT when the last component was a non-directory), and other paths
would be returned as though they were acceptable (trailing-slash components
after a non-directory would be ignored by Open(at)InRoot).
These changes were done to match openat2's behaviour and purely is a
consistency fix (most users are going to be using openat2 anyway).
However, it does introduce a new *os.File-based API which is much safer
to use for most usecases. These are adapted from [libpathrs][1] and are
the bare minimum to be able to operate more safely on an untrusted
rootfs where an attacker has write access (something that SecureJoin
cannot protect against). The new APIs are:
OpenInRoot, which resolves a path inside a rootfs and returns an
*os.File handle to the path. Note that the file handle returned by
OpenInRoot is an O_PATH handle, which cannot be used for reading or
writing (as well as some other operations -- see open(2) for more
details).
Reopen, which takes an O_PATH file handle and safely re-opens it to
"upgrade" it to a regular handle.
