patch adds a logic to utilize multiple queues to process requests.
The queue selection logic uses a round-robin distribution technique
using a counter.

test_progs'
Alexander Duyck says:
====================
Move the test functionality from test_tcpbpf_user into the test_progs
framework so that it will be run any time the test_progs framework is run.
This will help to prevent future test escapes as the individual tests, such
as test_tcpbpf_user, are less likely to be run by developers and CI
tests.
As a part of moving it over the series goes through and updates the code to
make use of the existing APIs included in the test_progs framework. This is
meant to simplify and streamline the test code and avoid duplication of
effort.
v2: Dropped test_tcpbpf_user from .gitignore
Replaced CHECK_FAIL calls with CHECK calls
Minimized changes in patch 1 when moving the file
Updated stg mail command line to display renames in submission
Added shutdown logic to end of run_test function to guarantee close
Added patch that replaces the two maps with use of global variables
v3: Left err at -1 while we are performing send/recv calls w/ data
Drop extra labels from test_tcpbpf_user in favor of keeping err label
Dropped redundant zero init for tcpbpf_globals result and key
Dropped replacing of "printf(" with "fprintf(stderr, "
Fixed error in use of ASSERT_OK_PTR which was skipping of run_test
Replaced "{ 0 }" with "{}" in init of global in test_tcpbpf_kern.c
Added "Acked-by" from Martin KaiFai Lau and Andrii Nakryiko

Use global variables instead of global_map and sockopt_results_map to track
test data. Doing this greatly simplifies the code as there is not need to
take the extra steps of updating the maps or looking up elements.

Update tcpbpf_user.c to make use of the BPF skeleton. Doing this we can
simplify test_tcpbpf_user and reduce the overhead involved in setting up
the test.
In addition we can clean up the remaining bits such as the one remaining
CHECK_FAIL at the end of test_tcpbpf_user so that the function only makes
use of CHECK as needed.

There is already logic in test_progs.h for asserting that a value is
expected to be another value. So instead of reinventing it we should just
make use of ASSERT_EQ in tcpbpf_user.c. This will allow for better
debugging and integrates much more closely with the test_progs framework.
In addition we can refactor the code a bit to merge together the two
verify functions and tie them together into a single function. Doing this
helps to clean the code up a bit and makes it more readable as all the
verification is now done in one function.
Lastly we can relocate the verification to the end of the run_test since it
is logically part of the test itself. With this we can drop the need for a
return value from run_test since verification becomes the last step of the
call and then immediately following is the tear down of the test setup.

Drop the tcp_client/server.py files in favor of using a client and server
thread within the test case. Specifically we spawn a new thread to play the
role of the server, and the main testing thread plays the role of client.
Add logic to the end of the run_test function to guarantee that the sockets
are closed when we begin verifying results.
Doing this we are able to reduce overhead since we don't have two python
workers possibly floating around. In addition we don't have to worry about
synchronization issues and as such the retry loop waiting for the threads
to close the sockets can be dropped as we will have already closed the
sockets in the local executable and synchronized the server thread.

Recently a bug was missed due to the fact that test_tcpbpf_user is not a
part of test_progs. In order to prevent similar issues in the future move
the test functionality into test_progs. By doing this we can make certain
that it is a part of standard testing and will not be overlooked.
As a part of moving the functionality into test_progs it is necessary to
integrate with the test_progs framework and to drop any redundant code.
This patch:
1. Cleans up the include headers
2. Dropped a duplicate definition of bpf_find_map
3. Switched over to using test_progs specific cgroup functions
4. Renamed main to test_tcpbpf_user
5. Dropped return value in favor of CHECK_FAIL to check for errors
The general idea is that I wanted to keep the changes as small as possible
while moving the file into the test_progs framework. The follow-on patches
are meant to clean up the remaining issues such as the use of CHECK_FAIL.

The usage of in_*() in drivers is phased out and Linus clearly requested
that code which changes behaviour depending on context should either be

dpaa_eth_napi_schedule() and caam_qi_napi_schedule() schedule NAPI if
invoked from:
- Hard interrupt context
- Any context which is not serving soft interrupts
Any context which is not serving soft interrupts includes hard interrupts
so the in_irq() check is redundant. caam_qi_napi_schedule() has a comment
about this:
/*
* In case of threaded ISR, for RT kernels in_irq() does not return
* appropriate value, so use in_serving_softirq to distinguish between
* softirq and irq contexts.
*/
if (in_irq() || !in_serving_softirq())
This has nothing to do with RT. Even on a non RT kernel force threaded
interrupts run obviously in thread context and therefore in_irq() returns
false when invoked from the handler.
The extension of the in_irq() check with !in_serving_softirq() was there
when the drivers were added, but in the out of tree FSL BSP the original
condition was in_irq() which got extended due to failures on RT.
The usage of in_xxx() in drivers is phased out and Linus clearly requested
that code which changes behaviour depending on context should either be
separated or the context be conveyed in an argument passed by the caller,
which usually knows the context. Right he is, the above construct is
clearly showing why.
The following callchains have been analyzed to end up in
dpaa_eth_napi_schedule():
qman_p_poll_dqrr()
__poll_portal_fast()
fq->cb.dqrr()
dpaa_eth_napi_schedule()
portal_isr()
__poll_portal_fast()
fq->cb.dqrr()
dpaa_eth_napi_schedule()
Both need to schedule NAPI.
The crypto part has another code path leading up to this:
kill_fq()
empty_retired_fq()
qman_p_poll_dqrr()
__poll_portal_fast()
fq->cb.dqrr()
dpaa_eth_napi_schedule()
kill_fq() is called from task context and ends up scheduling NAPI, but
that's pointless and an unintended side effect of the !in_serving_softirq()
check.
The code path:
caam_qi_poll() -> qman_p_poll_dqrr()
is invoked from NAPI and I *assume* from crypto's NAPI device and not
from qbman's NAPI device. I *guess* it is okay to skip scheduling NAPI
(because this is what happens now) but could be changed if it is wrong
due to `budget' handling.
Add an argument to __poll_portal_fast() which is true if NAPI needs to be
scheduled. This requires propagating the value to the caller including
`qman_cb_dqrr' typedef which is used by the dpaa and the crypto driver.

EROFS has _only one_ ondisk timestamp (ctime is currently
documented and recorded, we might also record mtime instead
with a new compat feature if needed) for each extended inode
since EROFS isn't mainly for archival purposes so no need to
keep all timestamps on disk especially for Android scenarios
due to security concerns. Also, romfs/cramfs don't have their
own on-disk timestamp, and squashfs only records mtime instead.
Let's also derive access time from ondisk timestamp rather than
leaving it empty, and if mtime/atime for each file are really
needed for specific scenarios as well, we can also use xattrs
to record them then.

Alexander Lobakin says:
====================
net: allow virtual netdevs to forward UDP L4 and fraglist GSO skbs
NETIF_F_GSO_UDP_L4 and NETIF_F_GSO_FRAGLIST allow drivers to offload
GSO UDP L4. This works well on simple setups, but when any logical
netdev (e.g. VLAN) is present, kernel stack always performs software
resegmentation which actually kills the performance.
The full path in such cases is like:
1. Our NIC driver advertises a support for fraglists, GSO UDP L4, GSO
fraglists.
2. User enables fraglisted GRO via Ethtool.
3. GRO subsystem receives UDP frames from driver and merges the packets
into fraglisted GSO skb(s).
4. Networking stack queues it up for xmitting.
5. Virtual device like VLAN doesn't advertise a support for GSO UDP L4
and GSO fraglists, so skb_gso_check() doesn't allow to pass this skb
as is to the real driver.
6. Kernel then has to form a bunch of regular UDP skbs from that one and
pass it to the driver instead. This fallback is *extremely* slow for
any GSO types, but especially for GSO fraglists.
7. All further processing performs with a series of plain UDP skbs, and
the driver gets it one-by-one, despite that it supports UDP L4 and
fraglisted GSO.
That's not OK because:
a) logical/virtual netdevs like VLANs, bridges etc. should pass GSO skbs
as is;
b) even if the final driver doesn't support such type of GSO, this
software resegmenting should be performed right before it, not in the
middle of processing -- I think I even saw that note somewhere in
kernel documentation, and it's totally reasonable in terms of
performance.
Despite the fact that no mainline drivers currently supports fraglist
GSO, this should and can be easily fixed by adding UDP L4 and fraglist
GSO to the list of GSO types that can be passed-through the logical
interfaces (NETIF_F_GSO_SOFTWARE). After this change, no resegmentation
occurs (if a particular driver supports and advertises this), and the
performance goes on par with e.g. 1:1 forwarding.
The only logical netdevs that seem to be unaffected to this are bridge
interfaces, as their code uses full NETIF_F_GSO_MASK.
Tested on MIPS32 R2 router board with a WIP NIC driver in VLAN NAT:
20 Mbps baseline, 1 Gbps / link speed with this patch.

netdevs to forward these types of skbs up to the real drivers.
