This release splits the errdefs package into the github.com/containerd/errdefs package which only contains error definitions as well as basic functions to check for those definitions and the github.com/containerd/errdefs/pkg package which containers functionality for using the errdefs, such as error serialization and adding more data to errors.
This release primarily includes fixes for spurious errors we hit when
checking that directories created by MkdirAll "look right". Upon further
consideration, these checks were fundamentally buggy and didn't offer
any practical protection anyway.
The mode and owner verification logic in MkdirAll has been removed. This
was originally intended to protect against some theoretical attacks but upon
further consideration these protections don't actually buy us anything and
they were causing spurious errors with more complicated filesystem setups.
The "is the created directory empty" logic in MkdirAll has also been
removed. This was not causing us issues yet, but some pseudofilesystems (such
as cgroup) create non-empty directories and so this logic would've been
wrong for such cases.
Thanks to all of the contributors who made this release possible:
This release includes a few fixes for MkdirAll when dealing with S_ISUID
and S_ISGID, to solve a regression runc hit when switching to MkdirAll.
Passing the S_ISUID or S_ISGID modes to MkdirAllInRoot will now return
an explicit error saying that those bits are ignored by mkdirat(2). In
the past a different error was returned, but since the silent ignoring
behaviour is codified in the man pages a more explicit error seems
apt. While silently ignoring these bits would be the most compatible
option, it could lead to users thinking their code sets these bits
when it doesn't. Programs that need to deal with compatibility can
mask the bits themselves. (#23, #25)
If a directory has S_ISGID set, then all child directories will have
S_ISGID set when created and a different gid will be used for any
inode created under the directory. Previously, the "expected owner and
mode" validation in securejoin.MkdirAll did not correctly handle this.
We now correctly handle this case. (#24, #25)
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.

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.
Technically this [will only work on post-2.6.39 kernels][linux-readlinkat-emptypath]
but it seems incredibly unlikely anyone is using filepath-securejoin on a
pre-2011 kernel.
