When we restore file descriptors we would like them to look exactly as
they were at dumping time.With help of fcntl it's almost possible, the missing snippet is file
owners UIDs.To be able to read their values the F_GETOWNER_UIDS is introduced.
This option is valid iif CONFIG_CHECKPOINT_RESTORE is turned on, otherwise

OK, what we have so far is e.g.
setxattr(path, name, whatever, 0, XATTR_REPLACE)
with name being good enough to get through xattr_permission().
Then we reach security_inode_setxattr() with the desired value and size.
Aha. name should begin with "security.selinux", or we won't get that
far in selinux_inode_setxattr(). Suppose we got there and have enough
permissions to relabel that sucker. We call security_context_to_sid()
with value == NULL, size == 0. OK, we want ss_initialized to be non-zero.
I.e. after everything had been set up and running. No problem...We do 1-byte kmalloc(), zero-length memcpy() (which doesn't oops, even
thought the source is NULL) and put a NUL there. I.e. form an empty
string. string_to_context_struct() is called and looks for the first
':' in there. Not found, -EINVAL we get. OK, security_context_to_sid_core()
has rc == -EINVAL, force == 0, so it silently returns -EINVAL.
All it takes now is not having CAP_MAC_ADMIN and we are fucked.All right, it might be a different bug (modulo strange code quoted in the
report), but it's real. Easily fixed, AFAICS:Deal with size == 0, value == NULL case in selinux_inode_setxattr()

Recently, glibc made a change to suppress sign-conversion warnings in
FD_SET (glibc commit ceb9e56b3d1). This uncovered an issue with the
kernel's definition of __NFDBITS if applications #include
after including . A build failure would
be seen when passing the -Werror=sign-compare and -D_FORTIFY_SOURCE=2
flags to gcc.It was suggested that the kernel should either match the glibc
definition of __NFDBITS or remove that entirely. The current in-kernel
uses of __NFDBITS can be replaced with BITS_PER_LONG, and there are no
uses of the related __FDELT and __FDMASK defines. Given that, we'll
continue the cleanup that was started with commit 8b3d1cda4f5f
("posix_types: Remove fd_set macros") and drop the remaining unused
macros.Additionally, linux/time.h has similar macros defined that expand to
nothing so we'll remove those at the same time.Reported-by: Jeff Law

Pull networking changes from David S Miller:
1) Remove the ipv4 routing cache. Now lookups go directly into the FIB
trie and use prebuilt routes cached there.No more garbage collection, no more rDOS attacks on the routing
cache. Instead we now get predictable and consistent performance,
no matter what the pattern of traffic we service.This has been almost 2 years in the making. Special thanks to
Julian Anastasov, Eric Dumazet, Steffen Klassert, and others who
have helped along the way.I'm sure that with a change of this magnitude there will be some
kind of fallout, but such things ought the be simple to fix at this
point. Luckily I'm not European so I'll be around all of August to
fix things :-)The major stages of this work here are each fronted by a forced
merge commit whose commit message contains a top-level description
of the motivations and implementation issues.2) Pre-demux of established ipv4 TCP sockets, saves a route demux on
input.3) TCP SYN/ACK performance tweaks from Eric Dumazet.
4) Add namespace support for netfilter L4 conntrack helpers, from Gao
Feng.5) Add config mechanism for Energy Efficient Ethernet to ethtool, from
Yuval Mintz.6) Remove quadratic behavior from /proc/net/unix, from Eric Dumazet.
7) Support for connection tracker helpers in userspace, from Pablo
Neira Ayuso.8) Allow userspace driven TX load balancing functions in TEAM driver,
from Jiri Pirko.9) Kill off NLMSG_PUT and RTA_PUT macros, more gross stuff with
embedded gotos.10) TCP Small Queues, essentially minimize the amount of TCP data queued
up in the packet scheduler layer. Whereas the existing BQL (Byte
Queue Limits) limits the pkt_sched --> netdevice queuing levels,
this controls the TCP --> pkt_sched queueing levels.From Eric Dumazet.
11) Reduce the number of get_page/put_page ops done on SKB fragments,
from Alexander Duyck.12) Implement protection against blind resets in TCP (RFC 5961), from
Eric Dumazet.13) Support the client side of TCP Fast Open, basically the ability to
send data in the SYN exchange, from Yuchung Cheng.Basically, the sender queues up data with a sendmsg() call using
MSG_FASTOPEN, then they do the connect() which emits the queued up
fastopen data.14) Avoid all the problems we get into in TCP when timers or PMTU events
hit a locked socket. The TCP Small Queues changes added a
tcp_release_cb() that allows us to queue work up to the
release_sock() caller, and that's what we use here too. From Eric
Dumazet.15) Zero copy on TX support for TUN driver, from Michael S. Tsirkin.

Pull the big VFS changes from Al Viro:
"This one is *big* and changes quite a few things around VFS. What's in there:- the first of two really major architecture changes - death to open
intents.The former is finally there; it was very long in making, but with
Miklos getting through really hard and messy final push in
fs/namei.c, we finally have it. Unlike his variant, this one
doesn't introduce struct opendata; what we have instead is
->atomic_open() taking preallocated struct file * and passing
everything via its fields.Instead of returning struct file *, it returns -E... on error, 0
on success and 1 in "deal with it yourself" case (e.g. symlink
found on server, etc.).See comments before fs/namei.c:atomic_open(). That made a lot of
goodies finally possible and quite a few are in that pile:
->lookup(), ->d_revalidate() and ->create() do not get struct
nameidata * anymore; ->lookup() and ->d_revalidate() get lookup
flags instead, ->create() gets "do we want it exclusive" flag.With the introduction of new helper (kern_path_locked()) we are rid
of all struct nameidata instances outside of fs/namei.c; it's still
visible in namei.h, but not for long. Come the next cycle,
declaration will move either to fs/internal.h or to fs/namei.c
itself. [me, miklos, hch]- The second major change: behaviour of final fput(). Now we have
__fput() done without any locks held by caller *and* not from deep
in call stack.That obviously lifts a lot of constraints on the locking in there.
Moreover, it's legal now to call fput() from atomic contexts (which
has immediately simplified life for aio.c). We also don't need
anti-recursion logics in __scm_destroy() anymore.There is a price, though - the damn thing has become partially
asynchronous. For fput() from normal process we are guaranteed
that pending __fput() will be done before the caller returns to
userland, exits or gets stopped for ptrace.For kernel threads and atomic contexts it's done via
schedule_work(), so theoretically we might need a way to make sure
it's finished; so far only one such place had been found, but there
might be more.There's flush_delayed_fput() (do all pending __fput()) and there's
__fput_sync() (fput() analog doing __fput() immediately). I hope
we won't need them often; see warnings in fs/file_table.c for
details. [me, based on task_work series from Oleg merged last
cycle]- sync series from Jan
- large part of "death to sync_supers()" work from Artem; the only
bits missing here are exofs and ext4 ones. As far as I understand,
those are going via the exofs and ext4 trees resp.; once they are
in, we can put ->write_super() to the rest, along with the thread
calling it.- preparatory bits from unionmount series (from dhowells).
- assorted cleanups and fixes all over the place, as usual.
This is not the last pile for this cycle; there's at least jlayton's
ESTALE work and fsfreeze series (the latter - in dire need of fixes,
so I'm not sure it'll make the cut this cycle). I'll probably throw
symlink/hardlink restrictions stuff from Kees into the next pile, too.
Plus there's a lot of misc patches I hadn't thrown into that one -

When I introduced open perms policy didn't understand them and I
implemented them as a policycap. When I added the checking of open perm
to truncate I forgot to conditionalize it on the userspace defined
policy capability. Running an old policy with a new kernel will not
check open on open(2) but will check it on truncate. Conditionalize the
truncate check the same as the open check.Signed-off-by: Eric Paris

This patch adds the following structure:
struct netlink_kernel_cfg {
unsigned int groups;
void (*input)(struct sk_buff *skb);
struct mutex *cb_mutex;
};That can be passed to netlink_kernel_create to set optional configurations
for netlink kernel sockets.I've populated this structure by looking for NULL and zero parameters at the
existing code. The remaining parameters that always need to be set are still
left in the original interface.That includes optional parameters for the netlink socket creation. This allows
easy extensibility of this interface in the future.This patch also adapts all callers to use this new interface.

With this change, calling
prctl(PR_SET_NO_NEW_PRIVS, 1, 0, 0, 0)
disables privilege granting operations at execve-time. For example, a
process will not be able to execute a setuid binary to change their uid
or gid if this bit is set. The same is true for file capabilities.Additionally, LSM_UNSAFE_NO_NEW_PRIVS is defined to ensure that
LSMs respect the requested behavior.To determine if the NO_NEW_PRIVS bit is set, a task may call
prctl(PR_GET_NO_NEW_PRIVS, 0, 0, 0, 0);
It returns 1 if set and 0 if it is not set. If any of the arguments are
non-zero, it will return -1 and set errno to -EINVAL.
(PR_SET_NO_NEW_PRIVS behaves similarly.)This functionality is desired for the proposed seccomp filter patch
series. By using PR_SET_NO_NEW_PRIVS, it allows a task to modify the
system call behavior for itself and its child tasks without being
able to impact the behavior of a more privileged task.Another potential use is making certain privileged operations
unprivileged. For example, chroot may be considered "safe" if it cannot
affect privileged tasks.Note, this patch causes execve to fail when PR_SET_NO_NEW_PRIVS is
set and AppArmor is in use. It is fixed in a subsequent patch.Signed-off-by: Andy Lutomirski

We pay a rather large overhead initializing the common_audit_data.

splits the functionality of avc_has_perm() into avc_has_perm_noaudit(),
avc_audit_required() and slow_avc_audit(). But we take care of setting
up to audit between required() and the actual audit call. Thus saving

I'm not really sure what the idea behind the sel_div function is, but it's
useless. Since a and b are both unsigned, it's impossible for a % b < 0.
That means that part of the function never does anything. Thus it's just a
normal /. Just do that instead. I don't even understand what that operation
was supposed to mean in the signed case however....If it was signed:
sel_div(-2, 4) == ((-2 / 4) - ((-2 % 4) < 0))
((0) - ((-2) < 0))
((0) - (1))
(-1)What actually happens:
sel_div(-2, 4) == ((18446744073709551614 / 4) - ((18446744073709551614 % 4) < 0))

We know that some yum operation is causing CAP_MAC_ADMIN failures. This
implies that an RPM is laying down (or attempting to lay down) a file with
an invalid label. The problem is that we don't have any information to
track down the cause. This patch will cause such a failure to report the
failed label in an SELINUX_ERR audit message. This is similar to the
SELINUX_ERR reports on invalid transitions and things like that. It should
help run down problems on what is trying to set invalid labels in the
future.Resulting records look something like:

dentry_open takes a file, rename it to file_open
Signed-off-by: Eric Paris
-
In RH BZ 578841 we realized that the SELinux sandbox program was allowed to
truncate files outside of the sandbox. The reason is because sandbox
confinement is determined almost entirely by the 'open' permission. The idea
was that if the sandbox was unable to open() files it would be unable to do
harm to those files. This turns out to be false in light of syscalls like
truncate() and chmod() which don't require a previous open() call. I looked
at the syscalls that did not have an associated 'open' check and found that
truncate(), did not have a seperate permission and even if it did have a
separate permission such a permission owuld be inadequate for use by
sandbox (since it owuld have to be granted so liberally as to be useless).
This patch checks the OPEN permission on truncate. I think a better solution
for sandbox is a whole new permission, but at least this fixes what we have
today.Signed-off-by: Eric Paris
