Subject: [PATCH] Revert "libselinux: restorecon: pin file to avoid TOCTOU

issues"
|

Content-type: text/plain
|

|

This reverts commit 7e979b56fd2cee28f647376a7233d2ac2d12ca50.
|
||||
|
||||
The reverted commit broke `setfiles` when it's run from a chroot
|
||||
without /proc mounted, e.g.
|
||||
|
||||
# chroot /mnt/sysimage
|
||||
|
||||
chroot# setfiles -e /proc -e /sys /sys /etc/selinux/targeted/contexts/files/file_contexts /
|
||||

||||

|
||||

|
||||

|
||||

|
||||
getxattr("/proc/self/fd/3", "security.selinux", 0x55be8881d3f0, 255) = -1 ENOENT (No such file or directory)
