net: udp: fix Fast/frag0 UDP GRO
While testing UDP GSO fraglists forwarding through driver that uses
Fast GRO (via napi_gro_frags()), I was observing lots of out-of-order
iperf packets:
[ ID] Interval Transfer Bitrate Jitter
[SUM] 0.0-40.0 sec 12106 datagrams received out-of-order
Simple switch to napi_gro_receive() or any other method without frag0
shortcut completely resolved them.
I've found two incorrect header accesses in GRO receive callback(s):
- udp_hdr() (instead of udp_gro_udphdr()) that always points to junk
in "fast" mode and could probably do this in "regular".
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.

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.

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.

Patch b2a846dbef ("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 b2a846dbef, 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.

This reverts commit b2a846dbef.
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.

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.

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. If it does,
xdr_inline_pages() underruns the length of the tail iovec.

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.

====================
cxgb4/ch_ktls: Fixes in nic tls code
This series helps in fixing multiple nic ktls issues. 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:

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.

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.

Commit 6f197fb638 ("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.
