IOSAPIC depends on PCI_LBA, so IOSAPIC is not set/enabled. Make the use of iosapic_serial_irq() conditional to fix the build error. Signed-off-by:

commit 57bc3d3a upstream. ax88179_rx_fixup() contains several out-of-bounds accesses that can be triggered by a malicious (or defective) USB device, in particular: - The metadata array (hdr_off..hdr_off+2*pkt_cnt) can be out of bounds, causing OOB reads and (on big-endian systems) OOB endianness flips. - A packet can overlap the metadata array, causing a later OOB endianness flip to corrupt data used by a cloned SKB that has already been handed off into the network stack. - A packet SKB can be constructed whose tail is far beyond its end, causing out-of-bounds heap data to be considered part of the SKB's data. I have tested that this can be used by a malicious USB device to send a bogus ICMPv6 Echo Request and receive an ICMPv6 Echo Reply in response that contains random kernel heap data. It's probably also possible to get OOB writes from this on a little-endian system somehow - maybe by triggering skb_cow() via IP options processing -, but I haven't tested that.

commit 1cf5f151 upstream. -Wunaligned-access is a new warning in clang that is default enabled for arm and arm64 under certain circumstances within the clang frontend (see LLVM commit below). On v5.17-rc2, an ARCH=arm allmodconfig build shows 1284 total/70 unique instances of this warning (most of the instances are in header files), which is quite noisy. To keep a normal build green through CONFIG_WERROR, only show this warning with W=1, which will allow automated build systems to catch new instances of the warning so that the total number can be driven down to zero eventually since catching unaligned accesses at compile time would be generally useful.

commit c0d79987 upstream. When setting the fan speed, i8k_set_fan() calls i8k_get_fan_status(), causing an unnecessary SMM call since from the two users of this function, only i8k_ioctl_unlocked() needs to know the new fan status while dell_smm_write() ignores the new fan status. Since SMM calls can be very slow while also making error reporting difficult for dell_smm_write(), remove the function call from i8k_set_fan() and call it separately in i8k_ioctl_unlocked(). Tested on a Dell Inspiron 3505. Signed-off-by:

commit 117b4e96 upstream. With CPU re-ordering on write instructions, there might be a chance that the HWO is set before the TRB is updated with the new mapped buffer address. And in the case where core is processing a list of TRBs it is possible that it fetched the TRBs when the HWO is set but before the buffer address is updated. Prevent this by adding a memory barrier before the HWO is updated to ensure that the core always process the updated TRBs.

commit 08389d88 upstream. Add a kconfig knob which allows for unprivileged bpf to be disabled by default. If set, the knob sets /proc/sys/kernel/unprivileged_bpf_disabled to value of 2. This still allows a transition of 2 -> {0,1} through an admin. Similarly, this also still keeps 1 -> {1} behavior intact, so that once set to permanently disabled, it cannot be undone aside from a reboot. We've also added extra2 with max of 2 for the procfs handler, so that an admin still has a chance to toggle between 0 <-> 2. Either way, as an additional alternative, applications can make use of CAP_BPF that we added a while ago. Signed-off-by:

[ Upstream commit 9eeabdf1 ] When uncloning an skb dst and its associated metadata, a new dst+metadata is allocated and later replaces the old one in the skb. This is helpful to have a non-shared dst+metadata attached to a specific skb. The issue is the uncloned dst+metadata is initialized with a refcount of 1, which is increased to 2 before attaching it to the skb. When tun_dst_unclone returns, the dst+metadata is only referenced from a single place (the skb) while its refcount is 2. Its refcount will never drop to 0 (when the skb is consumed), leading to a memory leak. Fix this by removing the call to dst_hold in tun_dst_unclone, as the dst+metadata refcount is already 1.

[ Upstream commit cfc56f85 ] When uncloning an skb dst and its associated metadata a new dst+metadata is allocated and the tunnel information from the old metadata is copied over there. The issue is the tunnel metadata has references to cached dst, which are copied along the way. When a dst+metadata refcount drops to 0 the metadata is freed including the cached dst entries. As they are also referenced in the initial dst+metadata, this ends up in UaFs. In practice the above did not happen because of another issue, the dst+metadata was never freed because its refcount never dropped to 0 (this will be fixed in a subsequent patch). Fix this by initializing the dst cache after copying the tunnel information from the old metadata to also unshare the dst cache.

[ Upstream commit 23de0d7b ] When 803.2ad mode enables a participating port, it should update the slave-array. I have observed that the member links are participating and are part of the active aggregator while the traffic is egressing via only one member link (in a case where two links are participating). Via kprobes I discovered that slave-arr has only one link added while the other participating link wasn't part of the slave-arr. I couldn't see what caused that situation but the simple code-walk through provided me hints that the enable_port wasn't always associated with the slave-array update.

This reverts commit 9f1a3c13. The upstream commit b400c2f4 ("net: axienet: Wait for PhyRstCmplt after core reset") add new instructions in the `__axienet_device_reset` function to wait until PhyRstCmplt bit is set, and return a non zero-exit value if this exceeds a timeout. However, its backported version in 4.9 (commit 9f1a3c13 ("net: axienet: Wait for PhyRstCmplt after core reset")) insert these instructions in `axienet_dma_bd_init` instead. Unlike upstream, the version of `__axienet_device_reset` currently present in branch stable/linux-4.9.y does not return an integer for error codes. Therefore fixing the backport cannot be as simple as moving the inserted instructions in the right place, and we simply revert it instead.
