This is a notty one. The behavour has indeed changed, ENOENT was the previous return and now we return EINVAL. I do not have a POSIX manual to hand, but the gist of the restriction is as below: Empty pathname In the original Unix, the empty pathname referred to the current directory. Nowadays POSIX decrees that an empty pathname must not be resolved successfully. Linux returns ENOENT in this case. It could be argued that the new behaviour is just as valid. A change is however unhelpful. Especially as kernel behaviour is exposed in chroots. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in Ubuntu. https://bugs.launchpad.net/bugs/817187 Title: change in readlink() errno in 2.6.39 and later kernels causes FTBFS for packages with older gnulib To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/817187/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

** Description changed: This is due to the following: http://lists.gnu.org/archive/html/bug-gnulib/2011-03/msg00308.html coreutils' make check failed on rawhide due to a kernel change in how readlink and readlinkat treat the empty file name.

A quick review of other syscalls reacting to as a pathname tend to now place readlink as an inconsistant outsider: open(, O_RDONLY) = -1 ENOENT (No such file or directory) chmod(, 0777) = -1 ENOENT (No such file or directory) readlink(, 0x7fff794533c0, 2048) = -1 EINVAL (Invalid argument) stat(, 0x7fff79453330)= -1 ENOENT (No such file or directory) rename(, ) = -1 ENOENT (No such file or directory) unlink() = -1 ENOENT (No such file or directory) -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in Ubuntu. https://bugs.launchpad.net/bugs/817187 Title: change in readlink() errno in 2.6.39 and later kernels causes FTBFS for packages with older gnulib To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/817187/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
