Hi José Bollo,
This will override the labels of user's home directories that set by
SELinux.
For example, if I run below command on SELinux enabled system:
$ useradd test
SELinux will label it as "user_u:object_r:user_home_dir_t:SystemLow"
first, and then useradd will reset the label as
"system_u:object_r:etc_t:SystemLow".
I got strace logs below:
723 openat(AT_FDCWD, "/proc/thread-self/attr/fscreate",
O_RDWR|O_CLOEXEC) = 11
723 write(11, "user_u:object_r:user_home_dir_t:"..., 35) = 35
723 close(11) = 0
723 mkdir("/home/t1", 000) = 0
723 chown("/home/t1", 1000, 1000) = 0
723 chmod("/home/t1", 0755) = 0
# SELinux labelled it as "user_home_dir_t" here.
723 llistxattr("/etc/skel", NULL, 0) = 17
723 llistxattr("/etc/skel", "security.selinux\0", 17) = 17
723 openat(AT_FDCWD, "/etc/xattr.conf", O_RDONLY) = -1 ENOENT (No such
file or directory)
723 lgetxattr("/etc/skel", "security.selinux", NULL, 0) = 27
723 lgetxattr("/etc/skel", "security.selinux",
"system_u:object_r:etc_t:s0", 27) = 27
723 lsetxattr("/home/t1", "security.selinux",
"system_u:object_r:etc_t:s0", 27, 0) = 0
# useradd reset the label as "etc_t" here.
Do you agree to move the patch to Smack specific layer? Such as
meta-security?
Thanks

Can't you reorder and rebase the patches so that this
0001-useradd.c-create-parent-directories-when-necessary.patch
applies on top of the patch which was submitted upstream?
I agree that it would be better to reorder. Better but less
conservative because an existing patch must be upgraded.
If upstream merges the proposed patch, then rebasing will be
inevitable at some point, so we might as well do the cleaner solution
now, even if the diff becomes larger.
"devtool modify shadow-native" might be useful for that. "git
rebase -i" in workspace/sources/shadow-native", then finish with
"devtool update-recipe shadow-native". I haven't tried whether
"update-recipe" handles re-ordering patches. If it doesn't, just
fix it manually.
I'll do and propose the new version soon.
Thanks!
I pushed a new version of the patch this monday. I suppose that it is
waiting for approval.
Best regards
José Bollo
