Subject: euidaccess/faccessat vs. ACLs
Date: Thu, 18 Sep 2014 14:25:05 +0200 [thread overview]
Message-ID: <541ACF21.5060105@redhat.com> (raw)
Hi,
the euidaccess and faccessat(AT_EACCESS) functions are emulated in glibc
and only look at the file's uid/gid. They do not take ACLs into
account, and this can cause subtle bugs. This should be noted in the
BUGS section.
Also, the AT_SYMLINK_NOFOLLOW flag to faccessat currently will not work
if specified alone, because Linux does not have an laccess() system
call. It works if specified together with AT_EACCESS, modulo the above
ACL bug of course.
Paolo
