commit 65de50969a77509452ae590e9449b70a22b923bb upstream.
Clang's static analysis tool reports these double free memory errors.
security/selinux/ss/services.c:2987:4: warning: Attempt to free released memory [unix.Malloc]
kfree(bnames[i]);
^~~~~~~~~~~~~~~~
security/selinux/ss/services.c:2990:2: warning: Attempt to free released memory [unix.Malloc]
kfree(bvalues);
^~~~~~~~~~~~~~
So improve the security_get_bools error handling by freeing these variables
and setting their return pointers to NULL and the return len to 0

[ Upstream commit 3b646abc5bc6c0df649daea4c2c976bd4d47e4c8 ]
Currently apparmor_sk_clone_security() does not check for existing
label/peer in the 'new' struct sock; it just overwrites it, if any
(with another reference to the label of the source sock.)
static void apparmor_sk_clone_security(const struct sock *sk,
struct sock *newsk)
{
struct aa_sk_ctx *ctx = SK_CTX(sk);
struct aa_sk_ctx *new = SK_CTX(newsk);
new->label = aa_get_label(ctx->label);
new->peer = aa_get_label(ctx->peer);
}
This might leak label references, which might overflow under load.
Thus, check for and put labels, to prevent such errors.
Note this is similarly done on:
static int apparmor_socket_post_create(struct socket *sock, ...)
...
if (sock->sk) {
struct aa_sk_ctx *ctx = SK_CTX(sock->sk);
aa_put_label(ctx->label);
ctx->label = aa_get_label(label);
}
...
Context:
-------
The label reference count leak is observed if apparmor_sock_graft()
is called previously: this sets the 'ctx->label' field by getting
a reference to the current label (later overwritten, without put.)
static void apparmor_sock_graft(struct sock *sk, ...)
{
struct aa_sk_ctx *ctx = SK_CTX(sk);
if (!ctx->label)
ctx->label = aa_get_current_label();
}
And that is the case on crypto/af_alg.c:af_alg_accept():
int af_alg_accept(struct sock *sk, struct socket *newsock, ...)
...
struct sock *sk2;
...
sk2 = sk_alloc(...);
...
security_sock_graft(sk2, newsock);
security_sk_clone(sk, sk2);
...
Apparently both calls are done on their own right, especially for
other LSMs, being introduced in 2010/2014, before apparmor socket
mediation in 2017 (see commits [1,2,3,4]).
So, it looks OK there! Let's fix the reference leak in apparmor.
Test-case:
---------
Exercise that code path enough to overflow label reference count.
$ cat aa-refcnt-af_alg.c
#include <stdio.h>
#include <string.h>
#include <unistd.h>
#include <sys/socket.h>
#include <linux/if_alg.h>
int main() {
int sockfd;
struct sockaddr_alg sa;
/* Setup the crypto API socket */
sockfd = socket(AF_ALG, SOCK_SEQPACKET, 0);
if (sockfd < 0) {
perror("socket");
return 1;
}
memset(&sa, 0, sizeof(sa));
sa.salg_family = AF_ALG;
strcpy((char *) sa.salg_type, "rng");
strcpy((char *) sa.salg_name, "stdrng");
if (bind(sockfd, (struct sockaddr *) &sa, sizeof(sa)) < 0) {
perror("bind");
return 1;
}
/* Accept a "connection" and close it; repeat. */
while (!close(accept(sockfd, NULL, 0)));
return 0;
}

[ Upstream commit dd2569fbb053719f7df7ef8fdbb45cf47156a701 ]
Fix two issues with introspecting the task mode.
1. If a task is attached to a unconfined profile that is not the
ns->unconfined profile then. Mode the mode is always reported
as -
$ ps -Z
LABEL PID TTY TIME CMD
unconfined 1287 pts/0 00:00:01 bash
test (-) 1892 pts/0 00:00:00 ps
instead of the correct value of (unconfined) as shown below
$ ps -Z
LABEL PID TTY TIME CMD
unconfined 2483 pts/0 00:00:01 bash
test (unconfined) 3591 pts/0 00:00:00 ps
2. if a task is confined by a stack of profiles that are unconfined
the output of label mode is again the incorrect value of (-) like
above, instead of (unconfined). This is because the visibile
profile count increment is skipped by the special casing of
unconfined.

[ Upstream commit 6cc7c266e5b47d3cd2b5bb7fd3aac4e6bb2dd1d2 ]
If the template field 'd' is chosen and the digest to be added to the
measurement entry was not calculated with SHA1 or MD5, it is
recalculated with SHA1, by using the passed file descriptor. However, this
cannot be done for boot_aggregate, because there is no file descriptor.
This patch adds a call to ima_calc_boot_aggregate() in
ima_eventdigest_init(), so that the digest can be recalculated also for the
boot_aggregate entry.

Don't immediately return if the signature is portable and security.ima is
not present. Just set error so that memory allocated is freed before
returning from evm_calc_hmac_or_hash().

It occurs when there is a failure during IMA initialization, and
ima_init_policy() is not called. IMA hooks still call ima_match_policy()
but ima_rules is NULL. This patch prevents the crash by directly assigning
the ima_default_policy pointer to ima_rules when ima_rules is defined. This
wouldn't alter the existing behavior, as ima_rules is always set at the end
of ima_init_policy().

commit 1129d31b55d509f15e72dc68e4b5c3a4d7b4da8d upstream.
Function hash_long() accepts unsigned long, while currently only one byte
is passed from ima_hash_key(), which calculates a key for ima_htable.
Given that hashing the digest does not give clear benefits compared to
using the digest itself, remove hash_long() and return the modulus
calculated on the first two bytes of the digest with the number of slots.
Also reduce the depth of the hash table by doubling the number of slots.

[ Upstream commit d4eaa2837851db2bfed572898bfc17f9a9f9151e ]
For kvmalloc'ed data object that contains sensitive information like
cryptographic keys, we need to make sure that the buffer is always cleared
before freeing it. Using memset() alone for buffer clearing may not
provide certainty as the compiler may compile it away. To be sure, the
special memzero_explicit() has to be used.
This patch introduces a new kvfree_sensitive() for freeing those sensitive
data objects allocated by kvmalloc(). The relevant places where
kvfree_sensitive() can be used are modified to use it.

[ Upstream commit a4ae32c71fe90794127b32d26d7ad795813b502e ]
An invariant of cap_bprm_set_creds is that every field in the new cred
structure that cap_bprm_set_creds might set, needs to be set every
time to ensure the fields does not get a stale value.
The field cap_ambient is not set every time cap_bprm_set_creds is
called, which means that if there is a suid or sgid script with an
interpreter that has neither the suid nor the sgid bits set the
interpreter should be able to accept ambient credentials.
Unfortuantely because cap_ambient is not reset to it's original value
the interpreter can not accept ambient credentials.
Given that the ambient capability set is expected to be controlled by
the caller, I don't think this is particularly serious. But it is
definitely worth fixing so the code works correctly.
I have tested to verify my reading of the code is correct and the
interpreter of a sgid can receive ambient capabilities with this
change and cannot receive ambient capabilities without this change.

commit c6b39f070722ea9963ffe756bfe94e89218c5e63 upstream.
policy_update() invokes begin_current_label_crit_section(), which
returns a reference of the updated aa_label object to "label" with
increased refcount.
When policy_update() returns, "label" becomes invalid, so the refcount
should be decreased to keep refcount balanced.
The reference counting issue happens in one exception handling path of
policy_update(). When aa_may_manage_policy() returns not NULL, the
refcnt increased by begin_current_label_crit_section() is not decreased,
causing a refcnt leak.
Fix this issue by jumping to "end_section" label when
aa_may_manage_policy() returns not NULL.

commit a0b845ffa0d91855532b50fc040aeb2d8338dca4 upstream.
aa_change_profile() invokes aa_get_current_label(), which returns
a reference of the current task's label.
According to the comment of aa_get_current_label(), the returned
reference must be put with aa_put_label().
However, when the original object pointed by "label" becomes
unreachable because aa_change_profile() returns or a new object
is assigned to "label", reference count increased by
aa_get_current_label() is not decreased, causing a refcnt leak.
Fix this by calling aa_put_label() before aa_change_profile() return
and dropping unnecessary aa_get_current_label().

commit c54d481d71c6849e044690d3960aaebc730224cc upstream.
In the implementation of aa_audit_rule_init(), when aa_label_parse()
fails the allocated memory for rule is released using
aa_audit_rule_free(). But after this release, the return statement
tries to access the label field of the rule which results in
use-after-free. Before releasing the rule, copy errNo and return it
after release.

[ Upstream commit 2e3a34e9f409ebe83d1af7cd2f49fca7af97dfac ]
This patch fixes the return value of ima_write_policy() when a new policy
is directly passed to IMA and the current policy requires appraisal of the
file containing the policy. Currently, if appraisal is not in ENFORCE mode,
ima_write_policy() returns 0 and leads user space applications to an
endless loop. Fix this issue by denying the operation regardless of the
appraisal mode.

[ Upstream commit 53de3b080d5eae31d0de219617155dcc34e7d698 ]
This patch avoids a kernel panic due to accessing an error pointer set by
crypto_alloc_shash(). It occurs especially when there are many files that
require an unsupported algorithm, as it would increase the likelihood of
the following race condition:
Task A: *tfm = crypto_alloc_shash() <= error pointer
Task B: if (*tfm == NULL) <= *tfm is not NULL, use it
Task B: rc = crypto_shash_init(desc) <= panic
Task A: *tfm = NULL
This patch uses the IS_ERR_OR_NULL macro to determine whether or not a new
crypto context must be created.

[ Upstream commit 0014cc04e8ec077dc482f00c87dfd949cfe2b98f ]
Commit a408e4a86b36 ("ima: open a new file instance if no read
permissions") tries to create a new file descriptor to calculate a file
digest if the file has not been opened with O_RDONLY flag. However, if a
new file descriptor cannot be obtained, it sets the FMODE_READ flag to
file->f_flags instead of file->f_mode.
This patch fixes this issue by replacing f_flags with f_mode as it was
before that commit.

[ Upstream commit 4f0882491a148059a52480e753b7f07fc550e188 ] By allocating a kernel buffer with a user-supplied buffer length, it is possible that a false positive ENOMEM error may be returned because the user-supplied length is just too large even if the system do have enough memory to hold the actual key data. Moreover, if the buffer length is larger than the maximum amount of memory that can be returned by kmalloc() (2^(MAX_ORDER-1) number of pages), a warning message will also be printed. To reduce this possibility, we set a threshold (PAGE_SIZE) over which we do check the actual key length first before allocating a buffer of the right size to hold it. The threshold is arbitrary, it is just used to trigger a buffer length check. It does not limit the actual key length as long as there is enough memory to satisfy the memory request. To further avoid large buffer allocation failure due to page fragmentation, kvmalloc() is used to allocate the buffer so that vmapped pages can be used when there is not a large enough contiguous set of pages available for allocation. In the extremely unlikely scenario that the key keeps on being changed and made longer (still <= buflen) in between 2 __keyctl_read_key() calls, the __keyctl_read_key() calling loop in keyctl_read_key() may have to be iterated a large number of times, but definitely not infinite.

One way to prevent this deadlock scenario from happening is to not
allow writing to userspace while holding the key semaphore. Instead,
an internal buffer is allocated for getting the keys out from the
read method first before copying them out to userspace without holding
the lock.
That requires taking out the __user modifier from all the relevant
read methods as well as additional changes to not use any userspace
write helpers. That is,
1) The put_user() call is replaced by a direct copy.
2) The copy_to_user() call is replaced by memcpy().
3) All the fault handling code is removed.
Compiling on a x86-64 system, the size of the rxrpc_read() function is
reduced from 3795 bytes to 2384 bytes with this patch.

commit 86d32f9a7c54ad74f4514d7fef7c847883207291 upstream.
If seq_file .next function does not change position index,
read after some lseek can generate unexpected output:
$ dd if=/proc/keys bs=1 # full usual output

But a read after lseek in middle of last line results in the partial

and a read after lseek beyond end of file results in the last line being

dd: /proc/keys: cannot skip to specified offset

commit 2e356101e72ab1361821b3af024d64877d9a798d upstream.
Currently, when we add a new user key, the calltrace as below:
add_key()
key_create_or_update()
key_alloc()
__key_instantiate_and_link
generic_key_instantiate
key_payload_reserve
......
Since commit a08bf91ce28e ("KEYS: allow reaching the keys quotas exactly"),
we can reach max bytes/keys in key_alloc, but we forget to remove this
limit when we reserver space for payload in key_payload_reserve. So we
can only reach max keys but not max bytes when having delta between plen
and type->def_datalen. Remove this limit when instantiating the key, so we
can keep consistent with key_alloc.
Also, fix the similar problem in keyctl_chown_key().

[ Upstream commit 030b995ad9ece9fa2d218af4429c1c78c2342096 ]
In AVC update we don't call avc_node_kill() when avc_xperms_populate()
fails, resulting in the avc->avc_cache.active_nodes counter having a
false value. In last patch this changes was missed , so correcting it.

[ Upstream commit 1f8266ff58840d698a1e96d2274189de1bdf7969 ]
As a comment above begin_current_label_crit_section() explains,
begin_current_label_crit_section() must run in sleepable context because
when label_is_stale() is true, aa_replace_current_label() runs, which uses
prepare_creds(), which can sleep.
Until now, the ptrace access check (which runs with a task lock held)
violated this rule.
Also add a might_sleep() assertion to begin_current_label_crit_section(),
because asserts are less likely to be ignored than comments.

[ Upstream commit 5f997580e8b12b9f585e34cc16304925d26ce49e ]
The netperf benchmark shows a 5.73% reduction in throughput for
small (64 byte) transfers by unconfined tasks.
DEFINE_AUDIT_SK() in aa_label_sk_perm() should not be performed
unconditionally, rather only when the label is confined.

Map the permission gating RTM_GETLINK messages to a new permission so that it can be distinguished from the other netlink route permissions in selinux policy. This is a temporary Android-only patch that will be deprecated in newer kernels once the long-term solution lands as discusssed on the mailing list [1]. The maintainer's recommended solution is more general, much more complex, and likely not suitable for backporting. This patch provides the minimal change needed for Android including the userspace settable trigger which ensures that the permission change is only applied to the newest version of Android which contains the changes needed for userpace compatibility. [1]: https://lore.kernel.org/selinux/20200116142653.61738-1-jeffv@google.com/ Bug: 141455849 Bug: 148218425 Test: CtsSelinuxTargetSdkCurrentTestCases Test: atest bionic-unit-tests-static Test: atest NetworkInterfaceTest Test: Connect to Wi-Fi network Test: Set up hotspot Test: Cast from device Test: Pair Bluetooth device Test: Call getifaddrs() directly from within an app. Test: Call NetworkInterface#getNetworkInterfaces() from within an app. Change-Id: I7b44ce60ad98f858c412722d41b9842f8577151f Signed-off-by: Jeff Vander Stoep <jeffv@google.com>
