commit 598e1a42e9626213565d3b22ea948ce78556512a upstream.
Commit 32a4f5ecd7 ("net: sched: introduce chain object to uapi")
added new RTM_* definitions without properly updating SELinux, this
patch adds the necessary SELinux support.
While there was a BUILD_BUG_ON() in the SELinux code to protect from
exactly this case, it was bypassed in the broken commit. In order to
hopefully prevent this from happening in the future, add additional
comments which provide some instructions on how to resolve the
BUILD_BUG_ON() failures.
Fixes: 32a4f5ecd7 ("net: sched: introduce chain object to uapi")

This allows filesystems to use their mount private data to
influence the permssions they return in permission2. It has
been separated into a new call to avoid disrupting current
permission users.

[AmitP: Minor refactoring of original patch to align with
changes from the following upstream commit
4bfd054ae1 ("fs: fold __inode_permission() into inode_permission()").
Also introduce vfs_mkobj2(), because do_create()
moved from using vfs_create() to vfs_mkobj()
eecec19d9e ("mqueue: switch to vfs_mkobj(), quit abusing ->d_fsdata")
do_create() is dropped/cleaned-up upstream so a
minor refactoring there as well.

When kernel.perf_event_open is set to 3 (or greater), disallow all
access to performance events by users without CAP_SYS_ADMIN.
Add a Kconfig symbol CONFIG_SECURITY_PERF_EVENTS_RESTRICT that
makes this value the default.
This is based on a similar feature in grsecurity
(CONFIG_GRKERNSEC_PERF_HARDEN). This version doesn't include making
the variable read-only. It also allows enabling further restriction
at run-time regardless of whether the default is changed.

commit c138325fb8713472d5a0c3c7258b9131bab40725 upstream.
selinux_sctp_bind_connect() must verify if the address buffer has
sufficient length before accessing the 'sa_family' field. See
__sctp_connect() for a similar check.
The length of the whole address ('len') is already checked in the
callees.

commit a408e4a86b36bf98ad15b9ada531cf0e5118ac67 upstream.
Open a new file instance as opposed to changing file->f_mode when
the file is not readable. This is done to accomodate overlayfs
stacked file operations change. The real struct file is hidden
behind the overlays struct file. So, any file->f_mode manipulations are
not reflected on the real struct file. Open the file again in read mode
if original file cannot be read, read and calculate the hash.

commit 7bb185edb0306bb90029a5fa6b9cff900ffdbf4b upstream.
commit 901ef845fa ("selinux: allow per-file labeling for cgroupfs")
broke mounting of cgroup2 under older SELinux policies which lacked
a genfscon rule for cgroup2. This prevents mounting of cgroup2 even
when SELinux is permissive.
Change the handling when there is no genfscon rule in policy to
just mark the inode unlabeled and not return an error to the caller.
This permits mounting and access if allowed by policy, e.g. to
unconfined domains.
I also considered changing the behavior of security_genfs_sid() to
never return -ENOENT, but the current behavior is relied upon by
other callers to perform caller-specific handling.

[ Upstream commit dcb569cf6ac99ca899b8109c128b6ae52477a015 ]
This fixes a pair of problems in the Smack ptrace checks
related to checking capabilities. In both cases, as reported
by Lukasz Pawelczyk, the raw capability calls are used rather
than the Smack wrapper that check addition restrictions.
In one case, as reported by Jann Horn, the wrong task is being
checked for capabilities.

This reverts commit 1f40a46cf4.
It turned out that this patch is not sufficient to enable PTI on 32 bit
systems with legacy 2-level page-tables. In this paging mode the huge-page
PTEs are in the top-level page-table directory, where also the mirroring to
the user-space page-table happens. So every huge PTE exits twice, in the
kernel and in the user page-table.
That means that accessed/dirty bits need to be fetched from two PTEs in
this mode to be safe, but this is not trivial to implement because it needs
changes to generic code just for the sake of enabling PTI with 32-bit
legacy paging. As all systems that need PTI should support PAE anyway,
remove support for PTI when 32-bit legacy paging is used.

Since this header is in "include/uapi/linux/", apparently people want to
use it in userspace programs -- even in C++ ones. However, the header
uses a C++ reserved keyword ("private"), so change that to "dh_private"
instead to allow the header file to be used in C++ userspace.

When kernel.perf_event_open is set to 3 (or greater), disallow all
access to performance events by users without CAP_SYS_ADMIN.
Add a Kconfig symbol CONFIG_SECURITY_PERF_EVENTS_RESTRICT that
makes this value the default.
This is based on a similar feature in grsecurity
(CONFIG_GRKERNSEC_PERF_HARDEN). This version doesn't include making
the variable read-only. It also allows enabling further restriction
at run-time regardless of whether the default is changed.

Bug: 29054680
Change-Id: Iff5bff4fc1042e85866df9faa01bce8d04335ab8
CAP_NET_ADMIN and CAP_NET_RAW are implicity granted to the "special"
Android groups net_admin and net_raw.
This is a byproduct of the init system not being able to specify
capabilities back in the day, but has now been resolved and .rc files
can explictly specify the capabilities to be granted to a service.
Thus, we should start to remove this implict capability grant, and the
first step is to warn when a process doesn't have explicit capablity
but is a member of the implicitly granted group, when that capability
is checked.
This will allow for the PARANOID_NETWORK checks in commoncap.c to
be totally removed in a future kernel.

changes.

flows active we don't traverse a long list during accumluation.

contributors to mention them all, but I'm really happy to keep
seeing this stuff.

instances and in fs/namei.c code around do_last()/lookup_open()/atomic_open().
- alloc_file() wrappers with saner calling conventions are introduced
(alloc_file_clone() and alloc_file_pseudo()); callers converted, with
much simplification.
- while we are at it, saner calling conventions for path_init() and
link_path_walk(), simplifying things inside fs/namei.c (both on
open-related paths and elsewhere).

The code in cap_inode_getsecurity(), introduced by commit 8db6c34f1d
("Introduce v3 namespaced file capabilities"), should use
d_find_any_alias() instead of d_find_alias() do handle unhashed dentry
correctly. This is needed, for example, if execveat() is called with an
open but unlinked overlayfs file, because overlayfs unhashes dentry on
unlink.
This is a regression of real life application, first reported at
https://www.spinics.net/lists/linux-unionfs/msg05363.html
Below reproducer and setup can reproduce the case.
const char* exec="echo";
const char *newargv[] = { "echo", "hello", NULL};
const char *newenviron[] = { NULL };
int fd, err;
fd = open(exec, O_PATH);
unlink(exec);
err = syscall(322/*SYS_execveat*/, fd, "", newargv, newenviron,
AT_EMPTY_PATH);
if(err<0)
fprintf(stderr, "execveat: %s\n", strerror(errno));
gcc compile into ~/test/a.out
mount -t overlay -orw,lowerdir=/mnt/l,upperdir=/mnt/u,workdir=/mnt/w
none /mnt/m
cd /mnt/m
cp /bin/echo .
~/test/a.out
Expected result:
hello
Actually result:
execveat: Invalid argument
dmesg:
Invalid argument reading file caps for /dev/fd/3
The 2nd reproducer and setup emulates similar case but for
regular filesystem:
const char* exec="echo";
int fd, err;
char buf[256];
fd = open(exec, O_RDONLY);
unlink(exec);
err = fgetxattr(fd, "security.capability", buf, 256);
if(err<0)
fprintf(stderr, "fgetxattr: %s\n", strerror(errno));
gcc compile into ~/test_fgetxattr
cd /tmp
cp /bin/echo .
~/test_fgetxattr
Result:
fgetxattr: Invalid argument
On regular filesystem, for example, ext4 read xattr from
disk and return to execveat(), will not trigger this issue, however,
the overlay attr handler pass real dentry to vfs_getxattr() will.
This reproducer calls fgetxattr() with an unlinked fd, involkes
vfs_getxattr() then reproduced the case that d_find_alias() in
cap_inode_getsecurity() can't find the unlinked dentry.
