2019-06-14Smack: Restore the smackfsdef mount option and add missing prefixesCasey Schaufler
The 5.1 mount system rework changed the smackfsdef mount option to smackfsdefault. This fixes the regression by making smackfsdef treated the same way as smackfsdefault. Also fix the smack_param_specs[] to have "smack" prefixes on all the names. This isn't visible to a user unless they either: (a) Try to mount a filesystem that's converted to the internal mount API and that implements the ->parse_monolithic() context operation - and only then if they call security_fs_context_parse_param() rather than security_sb_eat_lsm_opts(). There are no examples of this upstream yet, but nfs will probably want to do this for nfs2 or nfs3. (b) Use fsconfig() to configure the filesystem - in which case security_fs_context_parse_param() will be called. This issue is that smack_sb_eat_lsm_opts() checks for the "smack" prefix on the options, but smack_fs_context_parse_param() does not.

2019-06-14docs: cgroup-v1: convert docs to ReST and rename to *.rstMauro Carvalho Chehab
Convert the cgroup-v1 files to ReST format, in order to allow a later addition to the admin-guide. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

2019-06-14ima: Use designated initializers for struct ima_event_dataThiago Jung Bauermann
Designated initializers allow specifying only the members of the struct that need initialization. Non-mentioned members are initialized to zero. This makes the code a bit clearer (particularly in ima_add_boot_aggregate) and also allows adding a new member to the struct without having to update all struct initializations.

Before this patch, doing a zero-sized write to /proc/self/keycreate would check if the current task can create unlabeled keys (which would usually fail with -EACCESS and generate an AVC). Now it skips the check and correctly sets the task's keycreate_sid to 0. Bug report: https://bugzilla.redhat.com/show_bug.cgi?id=1719067 Tested using the reproducer from the report above.

2019-06-04ima: prevent a file already mmap'ed write to be mmap'ed executeMimi Zohar
The kernel calls deny_write_access() to prevent a file already opened for write from being executed and also prevents files being executed from being opened for write. For some reason this does not extend to files being mmap'ed execute. From an IMA perspective, measuring/appraising the integrity of a file being mmap'ed shared execute, without first making sure the file cannot be modified, makes no sense. This patch prevents files, in policy, already mmap'ed shared write, from being mmap'ed execute. Signed-off-by: Mimi Zohar <zohar@linux.ibm.com>

2019-05-20selinux: do not report error on connect(AF_UNSPEC)Paolo Abeni
calling connect(AF_UNSPEC) on an already connected TCP socket is an established way to disconnect() such socket. After commit 68741a8adab9 ("selinux: Fix ltp test connect-syscall failure") it no longer works and, in the above scenario connect() fails with EAFNOSUPPORT. Fix the above explicitly early checking for AF_UNSPEC family, and returning success in that case.

Commit cff0e6c3ec3e6230 ("tomoyo: Add a kernel config option for fuzzing testing.") enabled the learning mode, but syzkaller is detecting any "WARNING:" string as a crash. Thus, disable TOMOYO's quota warning if built for fuzzing testing.

2019-05-10tomoyo: Change pathname calculation for read-only filesystems.Tetsuo Handa
Commit 5625f2e3266319fd ("TOMOYO: Change pathname for non-rename()able filesystems.") intended to be applied to filesystems where the content is not controllable from the userspace (e.g. proc, sysfs, securityfs), based on an assumption that such filesystems do not support rename() operation. But it turned out that read-only filesystems also do not support rename() operation despite the content is controllable from the userspace, and that commit is annoying TOMOYO users who want to use e.g. squashfs as the root filesystem due to use of local name which does not start with '/'. Therefore, based on an assumption that filesystems which require the device argument upon mount() request is an indication that the content is controllable from the userspace, do not use local name if a filesystem does not support rename() operation but requires the device argument upon mount() request.
