tipc: re-fetch skb cb after tipc_msg_validate

As the call trace shows, the original skb was freed in tipc_msg_validate(),
and dereferencing the old skb cb would cause an use-after-free crash.

Description: In the Linux kernel, the following vulnerability has been resolved:

btrfs: fix inode list leak during backref walking at resolve_indirect_refs()

During backref walking, at resolve_indirect_refs(), if we get an error
we jump to the 'out' label and call ulist_free() on the 'parents' ulist,
which frees all the elements in the ulist - however that does not free
any inode lists that may be attached to elements, through the 'aux' field
of a ulist node, so we end up leaking lists if we have any attached to
the unodes.

Fix this by calling free_leaf_list() instead of ulist_free() when we exit
from resolve_indirect_refs(). The static function free_leaf_list() is
moved up for this to be possible and it's slightly simplified by removing
unnecessary code.

allocated pages, so use VM_MAP instead.

ipvlan: Fix out-of-bound bugs caused by unset skb->mac_header

If an AF_PACKET socket is used to send packets through ipvlan and the
default xmit function of the AF_PACKET socket is changed from
dev_queue_xmit() to packet_direct_xmit() via setsockopt() with the option
name of PACKET_QDISC_BYPASS, the skb->mac_header may not be reset and
remains as the initial value of 65535, this may trigger slab-out-of-bounds
bugs as following:

The root cause is:
  1. packet_snd() only reset skb->mac_header when sock->type is SOCK_RAW
     and skb->protocol is not specified as in packet_parse_headers()

  2. packet_direct_xmit() doesn't reset skb->mac_header as dev_queue_xmit()

In this case, skb->mac_header is 65535 when ipvlan_xmit_mode_l2() is
called. So when ipvlan_xmit_mode_l2() gets mac header with eth_hdr() which
use "skb->head + skb->mac_header", out-of-bound access occurs.

This patch replaces eth_hdr() with skb_eth_hdr() in ipvlan_xmit_mode_l2()
and reset mac header in multicast to solve this out-of-bound bug.

Statement: This issue only impacts applications running on Java version 6 and lower. Additionally, this vulnerability impacts code running on Unix-like systems, and very old versions of Mac OSX and Windows as they all share the system temporary directory between all users.

Red Hat Satellite 6 is not affected as is using netty 3.6.7 version which is not impacted by this vulnerability.

Red Hat Fuse 7 is now in Maintenance Support Phase and should be fixed soon. However, Red Hat Fuse Online (Syndesis) does will not contain the fix for this flaw.
Mitigation: As a workaround, specify one's own `java.io.tmpdir` when starting the JVM or use DefaultHttpDataFactory.setBaseDir(...) to set the directory to something that is only readable by the current user.

CWE: CWE-415
Description: A double-free vulnerability has been identified within the Linux kernel. This issue arises from a sequence of function calls involving create_hist_field(), init_var_ref(), and destroy_hist_field(). Specifically, init_var_ref() allocates memory for fields within a variable (ref_field->system). However, if an error occurs within init_var_ref(), these newly allocated fields are prematurely freed. Subsequently, the calling function invokes destroy_hist_field() as part of its error handling routine. This function then attempts to free the same fields, along with the variable itself, resulting in a double-free condition. Successful exploitation can lead to memory corruption and potentially a denial-of-service.
Statement: The requirement for administrator-level privileges to trigger this issue decreases the associated risk for standard user accounts. Access to the affected kernel debugging and tracing interfaces is intentionally restricted, thereby limiting the potential for widespread exploitation or compromise by unprivileged users.
Mitigation: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

An unprivileged (in case of unprivileged user namespaces enabled, otherwise needs namespaced CAP_SYS_ADMIN privilege) local user able to open a filesystem that does not support the Filesystem Context API (and thus fallbacks to legacy handling) could use this flaw to escalate their privileges on the system.
Statement: This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 8.4 GA onwards. Previous Red Hat Enterprise Linux versions are not affected.
Mitigation: On non-containerized deployments of Red Hat Enterprise Linux 8, you can disable user namespaces by setting user.max_user_namespaces to 0:

# echo "user.max_user_namespaces=0" > /etc/sysctl.d/userns.conf
# sysctl -p /etc/sysctl.d/userns.conf

On containerized deployments, such as Red Hat OpenShift Container Platform, do not use this mitigation as the functionality is needed to be enabled.
