Description Miroslav Grepl 2012-01-16 13:22:30 UTC

Description of problem:

sftp/chroot option either runs in the old sftpd_t domain or in the sshd_t domain which is not correct.

Comment 1 Petr Lautrbach 2012-02-02 16:24:10 UTC

With removed openssh-5.8p1-sftpcontext.patch and with added openssh-5.8p2-sftp-chroot.patch (similar to openssh-5.9p1-sftp-chroot.patch from Rawhide) I get this behaviour:

1.
ChrootDirectory none
Subsystem       sftp internal-sftp

system_u:system_r:sshd_t:s0-s0:c0.c1023  /usr/sbin/sshd -D
system_u:system_r:sshd_t:s0-s0:c0.c1023   \_ sshd: staff [priv]
system_u:system_r:sshd_t:s0-s0:c0.c1023       \_ sshd: staff@notty
staff_u:staff_r:staff_t:s0                      \_ sshd: staff@internal-sftp

2.
ChrootDirectory none
Subsystem       sftp    /usr/libexec/openssh/sftp-server

system_u:system_r:sshd_t:s0-s0:c0.c1023  /usr/sbin/sshd -D
system_u:system_r:sshd_t:s0-s0:c0.c1023   \_ sshd: staff [priv]
system_u:system_r:sshd_t:s0-s0:c0.c1023       \_ sshd: staff@notty
staff_u:staff_r:staff_t:s0                     \_ /usr/libexec/openssh/sftp-server

3. 
ChrootDirectory /chroot
Subsystem       sftp internal-sftp

system_u:system_r:sshd_t:s0-s0:c0.c1023      /usr/sbin/sshd -D
system_u:system_r:sshd_t:s0-s0:c0.c1023       \_ sshd: staff [priv]
system_u:system_r:chroot_user_t:s0-s0:c0.c1023  \_ sshd: staff@notty
system_u:system_r:chroot_user_t:s0-s0:c0.c1023    \_ sshd: staff@internal-sftp


Is this what you expect?
