58284a9 Anshuman Khandual 13 November 2020, 07:30:14 UTC arm64/mm: Validate hotplug range before creating linear mapping During memory hotplug process, the linear mapping should not be created for a given memory range if that would fall outside the maximum allowed linear range. Else it might cause memory corruption in the kernel virtual space. Maximum linear mapping region is [PAGE_OFFSET..(PAGE_END -1)] accommodating both its ends but excluding PAGE_END. Max physical range that can be mapped inside this linear mapping range, must also be derived from its end points. This ensures that arch_add_memory() validates memory hot add range for its potential linear mapping requirements, before creating it with __create_pgd_mapping().

This was the actual bug that caused all out-of-order delivers; - udp{4,6}_lib_lookup_skb() -> ip{,v6}_hdr() (instead of skb_gro_network_header()) that potentionally might return odd pointers in both modes. Each patch addresses one of these two issues. This doesn't cover a support for nested tunnels as it's out of the subject and requires more invasive changes. It will be handled separately in net-next series.

55e7298 Alexander Lobakin 11 November 2020, 20:45:38 UTC net: udp: fix IP header access and skb lookup on Fast/frag0 UDP GRO udp{4,6}_lib_lookup_skb() use ip{,v6}_hdr() to get IP header of the packet. While it's probably OK for non-frag0 paths, this helpers will also point to junk on Fast/frag0 GRO when all headers are located in frags. As a result, sk/skb lookup may fail or give wrong results. To support both GRO modes, skb_gro_network_header() might be used. To not modify original functions, add private versions of udp{4,6}_lib_lookup_skb() only to perform correct sk lookups on GRO.

4b1a862 Alexander Lobakin 11 November 2020, 20:45:25 UTC net: udp: fix UDP header access on Fast/frag0 UDP GRO UDP GRO uses udp_hdr(skb) in its .gro_receive() callback. While it's probably OK for non-frag0 paths (when all headers or even the entire frame are already in skb head), this inline points to junk when using Fast GRO (napi_gro_frags() or napi_gro_receive() with only Ethernet header in skb head and all the rest in the frags) and breaks GRO packet compilation and the packet flow itself. To support both modes, skb_gro_header_fast() + skb_gro_header_slow() are typically used. UDP even has an inline helper that makes use of them, udp_gro_udphdr(). Use that instead of troublemaking udp_hdr() to get rid of the out-of-order delivers. Present since the introduction of plain UDP GRO in 5.0-rc1.

4e79e3f Bob Peterson 12 November 2020, 16:02:48 UTC gfs2: Fix case in which ail writes are done to jdata holes Patch b2a846dbef4e ("gfs2: Ignore journal log writes for jdata holes") tried (unsuccessfully) to fix a case in which writes were done to jdata blocks, the blocks are sent to the ail list, then a punch_hole or truncate operation caused the blocks to be freed. In other words, the ail items are for jdata holes. Before b2a846dbef4e, the jdata hole caused function gfs2_block_map to return -EIO, which was eventually interpreted as an IO error to the journal, and then withdraw. This patch changes function gfs2_get_block_noalloc, which is only used for jdata writes, so it returns -ENODATA rather than -EIO, and when -ENODATA is returned to gfs2_ail1_start_one, the error is ignored. We can safely ignore it because gfs2_ail1_start_one is only called when the jdata pages have already been written and truncated, so the ail1 content no longer applies.

d3039c0 Bob Peterson 11 November 2020, 17:09:55 UTC Revert "gfs2: Ignore journal log writes for jdata holes" This reverts commit b2a846dbef4ef54ef032f0f5ee188c609a0278a7. That commit changed the behavior of function gfs2_block_map to return -ENODATA in cases where a hole (IOMAP_HOLE) is encountered and create is false. While that fixed the intended problem for jdata, it also broke other callers of gfs2_block_map such as some jdata block reads. Before the patch, an encountered hole would be skipped and the buffer seen as unmapped by the caller. The patch changed the behavior to return -ENODATA, which is interpreted as an error by the caller. The -ENODATA return code should be restricted to the specific case where jdata holes are encountered during ail1 writes. That will be done in a later patch.

9e2b7fa Martin Willi 06 November 2020, 07:30:30 UTC vrf: Fix fast path output packet handling with async Netfilter rules VRF devices use an optimized direct path on output if a default qdisc is involved, calling Netfilter hooks directly. This path, however, does not consider Netfilter rules completing asynchronously, such as with NFQUEUE. The Netfilter okfn() is called for asynchronously accepted packets, but the VRF never passes that packet down the stack to send it out over the slave device. Using the slower redirect path for this seems not feasible, as we do not know beforehand if a Netfilter hook has asynchronously completing rules. Fix the use of asynchronously completing Netfilter rules in OUTPUT and POSTROUTING by using a special completion function that additionally calls dst_output() to pass the packet down the stack. Also, slightly adjust the use of nf_reset_ct() so that is called in the asynchronous case, too.

6c2190b Chuck Lever 31 October 2020, 16:44:25 UTC NFS: Fix listxattr receive buffer size Certain NFSv4.2/RDMA tests fail with v5.9-rc1. rpcrdma_convert_kvec() runs off the end of the rl_segments array because rq_rcv_buf.tail[0].iov_len holds a very large positive value. The resultant kernel memory corruption is enough to crash the client system. Callers of rpc_prepare_reply_pages() must reserve an extra XDR_UNIT in the maximum decode size for a possible XDR pad of the contents of the xdr_buf's pages. That guarantees the allocated receive buffer will be large enough to accommodate the usual contents plus that XDR pad word. encode_op_hdr() cannot add that extra word.

d19d8d3 Eric Biggers 11 November 2020, 01:52:24 UTC fscrypt: fix inline encryption not used on new files The new helper function fscrypt_prepare_new_inode() runs before S_ENCRYPTED has been set on the new inode. This accidentally made fscrypt_select_encryption_impl() never enable inline encryption on newly created files, due to its use of fscrypt_needs_contents_encryption() which only returns true when S_ENCRYPTED is set. Fix this by using S_ISREG() directly instead of fscrypt_needs_contents_encryption(), analogous to what select_encryption_mode() does. I didn't notice this earlier because by design, the user-visible behavior is the same (other than performance, potentially) regardless of whether inline encryption is used or not.

Series is broken into 12 patches. Patch 1 avoids deciding tls packet based on decrypted bit. If its a retransmit packet which has tls handshake and finish (for encryption), decrypted bit won't be set there, and so we can't rely on decrypted bit. Patch 2 helps supporting linear skb. SKBs were assumed non-linear. Corrected the length extraction. Patch 3 fixes the checksum offload update in WR. Patch 4 fixes kernel panic happening due to creating new skb for each record. As part of fix driver will use same skb to send out one tls record (partial data) of the same SKB. Patch 5 fixes the problem of skb data length smaller than remaining data of the record. Patch 6 fixes the handling of SKBs which has tls header alone pkt, but not starting from beginning. Patch 7 avoids sending extra data which is used to make a record 16 byte aligned. We don't need to retransmit those extra few bytes. Patch 8 handles the cases where retransmit packet has tls starting exchanges which are prior to tls start marker. Patch 9 fixes the problem os skb free before HW knows about tcp FIN. Patch 10 handles the small packet case which has partial TAG bytes only. HW can't handle those, hence using sw crypto for such pkts. Patch 11 corrects the potential tcb update problem. Patch 12 stops the queue if queue reaches threshold value. v1->v2: - Corrected fixes tag issue. - Marked chcr_ktls_sw_fallback() static. v2->v3: - Replaced GFP_KERNEL with GFP_ATOMIC. - Removed mixed fixes. v3->v4: - Corrected fixes tag issue. v4->v5: - Separated mixed fixes from patch 4. v5-v6: - Fixes tag should be at the end. ==================== Link: https://lore.kernel.org/r/20201109105142.15398-1-rohitm@chelsio.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> 12 November 2020, 00:30:42 UTC

687823d Rohit Maheshwari 09 November 2020, 10:51:34 UTC cxgb4/ch_ktls: creating skbs causes panic Creating SKB per tls record and freeing the original one causes panic. There will be race if connection reset is requested. By freeing original skb, refcnt will be decremented and that means, there is no pending record to send, and so tls_dev_del will be requested in control path while SKB of related connection is in queue. Better approach is to use same SKB to send one record (partial data) at a time. We still have to create a new SKB when partial last part of a record is requested. This fix introduces new API cxgb4_write_partial_sgl() to send partial part of skb. Present cxgb4_write_sgl can only provide feasibility to start from an offset which limits to header only and it can write sgls for the whole skb len. But this new API will help in both. It can start from any offset and can end writing in middle of the skb. v4->v5: - Removed extra changes.

2b52a4b Sven Van Asbroeck 09 November 2020, 20:38:28 UTC lan743x: fix "BUG: invalid wait context" when setting rx mode In the net core, the struct net_device_ops -> ndo_set_rx_mode() callback is called with the dev->addr_list_lock spinlock held. However, this driver's ndo_set_rx_mode callback eventually calls lan743x_dp_write(), which acquires a mutex. Mutex acquisition may sleep, and this is not allowed when holding a spinlock. Fix by removing the dp_lock mutex entirely. Its purpose is to prevent concurrent accesses to the data port. No concurrent accesses are possible, because the dev->addr_list_lock spinlock in the core only lets through one thread at a time.

902a66e Sven Van Asbroeck 08 November 2020, 17:12:24 UTC lan743x: correctly handle chips with internal PHY Commit 6f197fb63850 ("lan743x: Added fixed link and RGMII support") assumes that chips with an internal PHY will never have a devicetree entry. This is incorrect: even for these chips, a devicetree entry can be useful e.g. to pass the mac address from bootloader to chip: &pcie { status = "okay"; host@0 { reg = <0 0 0 0 0>; #address-cells = <3>; #size-cells = <2>; lan7430: ethernet@0 { /* LAN7430 with internal PHY */ compatible = "microchip,lan743x"; status = "okay"; reg = <0 0 0 0 0>; /* filled in by bootloader */ local-mac-address = [00 00 00 00 00 00]; }; }; }; If a devicetree entry is present, the driver will not attach the chip to its internal phy, and the chip will be non-operational. Fix by tweaking the phy connection algorithm: - first try to connect to a phy specified in the devicetree (could be 'real' phy, or just a 'fixed-link') - if that doesn't succeed, try to connect to an internal phy, even if the chip has a devnode Tested on a LAN7430 with internal PHY. I cannot test a device using fixed-link, as I do not have access to one.

Some privileged drivers/applications need read access to this data, but don't expose it to non-privileged users. For example, thermald uses this data to ensure that power management works correctly. Thus removing non-privileged access is preferred over completely disabling this power reporting capability with CONFIG_INTEL_RAPL=n.

Therefore our handling of erratum 1418040 does not get activated if it is not required by any of the boot CPUs, even though we allow late-onlining of an affected CPU.

This was hidden before because we wrongly did that in hw_reset() before which was an unintended use of hw_reset(). Now that we corrected the use of hw_reset() meanwhile, we revealed this shortcoming and need to fix it properly by explicitly calling the downgrade callback.
