2021-04-18netfilter: Dissect flow after packet manglingIdo Schimmel
Netfilter tries to reroute mangled packets as a different route might need to be used following the mangling. When this happens, netfilter does not populate the IP protocol, the source port and the destination port in the flow key. Therefore, FIB rules that match on these fields are ignored and packets can be misrouted. Solve this by dissecting the outer flow and populating the flow key before rerouting the packet. Note that flow dissection only happens when FIB rules that match on these fields are installed, so in the common case there should not be a penalty.

2021-04-18netfilter: nftables_offload: special ethertype handling for VLANPablo Neira Ayuso
The nftables offload parser sets FLOW_DISSECTOR_KEY_BASIC .n_proto to the ethertype field in the ethertype frame. However: - FLOW_DISSECTOR_KEY_BASIC .n_proto field always stores either IPv4 or IPv6 ethertypes. - FLOW_DISSECTOR_KEY_VLAN .vlan_tpid stores either the 802.1q and 802.1ad ethertypes. Same as for FLOW_DISSECTOR_KEY_CVLAN. This function adjusts the flow dissector to handle two scenarios: 1) FLOW_DISSECTOR_KEY_VLAN .vlan_tpid is set to 802.1q or 802.1ad. Then, transfer: - the .n_proto field to FLOW_DISSECTOR_KEY_VLAN .tpid. - the original FLOW_DISSECTOR_KEY_VLAN .tpid to the FLOW_DISSECTOR_KEY_CVLAN .tpid - the original FLOW_DISSECTOR_KEY_CVLAN .tpid to the .n_proto field. 2) .n_proto is set to 802.1q or 802.1ad. Then, transfer: - the .n_proto field to FLOW_DISSECTOR_KEY_VLAN .tpid. - the original FLOW_DISSECTOR_KEY_VLAN .tpid to the .n_proto field.

Since uprobes is not supported for thumb, check that the thumb bit is not set when matching the uprobes instruction hooks. The Arm UDF instructions used for uprobes triggering (UPROBE_SWBP_ARM_INSN and UPROBE_SS_ARM_INSN) coincidentally share the same encoding as a pair of unallocated 32-bit thumb instructions (not UDF) when the condition code is 0b1111 (0xf). This in effect makes it possible to trigger the uprobes functionality from thumb, and at that using two unallocated instructions which are not permanently undefined.

2021-04-18powerpc/powernv: Enable HAIL (HV AIL) for ISA v3.1 processorsNicholas Piggin
Starting with ISA v3.1, LPCR[AIL] no longer controls the interrupt mode for HV=1 interrupts. Instead, a new LPCR[HAIL] bit is defined which behaves like AIL=3 for HV interrupts when set. Set HAIL on bare metal to give us mmu-on interrupts and improve performance. This also fixes an scv bug: we don't implement scv real mode (AIL=0) vectors because they are at an inconvenient location, so we just disable scv support when AIL can not be set. However powernv assumes that LPCR[AIL] will enable AIL mode so it enables scv support despite HV interrupts being AIL=0, which causes scv interrupts to go off into the weeds.

To fix that, but not require reverting commit 1ed08f6fb5ae ("iwlwifi: remove flags argument for nic_access"), split up nic access into a version with BH manipulation to use most of the time, and without it for this specific case where the local IRQs are already disabled.

2021-04-17fs: fix reporting supported extra file attributes for statx()Theodore Ts'o
statx(2) notes that any attribute that is not indicated as supported by stx_attributes_mask has no usable value. Commits 801e523796004 ("fs: move generic stat response attr handling to vfs_getattr_nosec") and 712b2698e4c02 ("fs/stat: Define DAX statx attribute") sets STATX_ATTR_AUTOMOUNT and STATX_ATTR_DAX, respectively, without setting stx_attributes_mask, which can cause xfstests generic/532 to fail. Fix this in the same way as commit 1b9598c8fb99 ("xfs: fix reporting supported extra file attributes for statx()") Fixes: 801e523796004 ("fs: move generic stat response attr handling to vfs_getattr_nosec") Fixes: 712b2698e4c02 ("fs/stat: Define DAX statx attribute") Cc: stable@kernel.org Signed-off-by: Theodore Ts'o <tytso@mit.edu>

Move restriction checks of __io_uring_register() before quiesce, saves from waiting for requests in fail case and simplifies the code a bit.

Colin reported before possible overflow and sign extension problems in io_provide_buffers_prep(). As Linus pointed out previous attempt did nothing useful, see d81269fecb8ce ("io_uring: fix provide_buffers sign extension"). Do that with help of check_<op>_overflow helpers. And fix struct io_provide_buf::len type, as it doesn't make much sense to keep it signed.

2021-04-17io_uring: don't fail submit with overflow backlogPavel Begunkov
Don't fail submission attempts if there are CQEs in the overflow backlog, but give away the decision making to the userspace. It might be very inconvenient to the userspace, especially if submission and completion are done by different threads. We can remove it because of recent changes, where requests are now not locked by the backlog, backlog entries are allocated separately, so they take less space and cgroup accounted.

into drm-fixes vmwgfx fixes for regressions in 5.12 Here's a set of 3 patches fixing ugly regressions in the vmwgfx driver. We broke lock initialization code and ended up using spinlocks before initialization breaking lockdep. Also there was a bit of a fallout from drm changes which made the core validate that unreferenced buffers have been unpinned. vmwgfx pinning code predates a lot of the core drm and wasn't written to account for those semantics. Fortunately changes required to fix it are not too intrusive. The changes have been validated by our internal ci.

2021-04-17r8169: keep pause settings on interface down/up cycleHeiner Kallweit
Currently, if the user changes the pause settings, the default settings will be restored after an interface down/up cycle, and also when resuming from suspend. This doesn't seem to provide the best user experience. Change this to keep user settings, and just ensure that in jumbo mode pause is disabled. Small drawback: When switching back mtu from jumbo to non-jumbo then pause remains disabled (but user can enable it using ethtool). I think that's a not too common scenario and acceptable.
