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.
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.
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).
