Intel USB4 host routers that run the firmware based connection manager
(ICM) may implement a proxy for USB4 router operations. This is to avoid
the firmware to race with the OS driver, as both may need to run these
operations.
This adds two new connection manager specific callbacks which, if
provided, get called instead of the native USB4 router operation.

We are going to make usb4_switch_op() to match better the corresponding
firmware (ICM) USB4 router operation proxy interface, so that we can use
either based on the connection manager implementation.
For this reason rename usb4_switch_op() to __usb4_switch_op() that
provides the most complete interface. Then make usb4_switch_op() and
usb4_switch_op_data() call it with correct set of parameters and update
the callers accordingly.

The currect code expects that the router returns back the status of the
NVM authentication immediately. When tested against a real USB4 device
what happens is that the router is reset and only after that the result
is updated in the ROUTER_CS_26 register status field. This also seems to
align better what the spec suggests.
For this reason do the same what we already do with the Thunderbolt 3
devices and perform the NVM upgrade in two phases. First start the
NVM_AUTH router operation and once the router is added back after the
reset read the status in ROUTER_CS_26 and expose it to the userspace
accordingly.

This driver allows sending DMA traffic over XDomain connection.
Specifically over a loopback connection using either a Thunderbolt/USB4
cable that is connected back to the host router port, or a special
loopback dongle that has RX and TX lines crossed. This can be useful at
manufacturing floor to check whether Thunderbolt/USB4 ports are
functional.
The driver exposes debugfs directory under the XDomain service that can
be used to configure the driver, start the test and check the results.
If a loopback dongle is used the steps to send and receive 1000 packets
can be done like:
# modprobe thunderbolt_dma_test
# echo 1000 > /sys/kernel/debug/thunderbolt/<service_id>/dma_test/packets_to_receive
# echo 1000 > /sys/kernel/debug/thunderbolt/<service_id>/dma_test/packets_to_send
# echo 1 > /sys/kernel/debug/thunderbolt/<service_id>/dma_test/test
# cat /sys/kernel/debug/thunderbolt/<service_id>/dma_test/status
When a cable is connected back to host then there are two Thunderbolt
services, one is configured for receiving (does not matter which one):
# modprobe thunderbolt_dma_test
# echo 1000 > /sys/kernel/debug/thunderbolt/<service_a>/dma_test/packets_to_receive
# echo 1 > /sys/kernel/debug/thunderbolt/<service_a>/dma_test/test
The other one for sending:
# echo 1000 > /sys/kernel/debug/thunderbolt/<service_b>/dma_test/packets_to_send
# echo 1 > /sys/kernel/debug/thunderbolt/<service_b>/dma_test/test
Results can be read from both services status attributes.

USB4 spec defines end-to-end (E2E) flow control that can be used between
hosts to prevent overflow of a RX ring. We previously had this partially
implemented but that code was removed with commit 53f13319d1
("thunderbolt: Get rid of E2E workaround") with the idea that we add it
back properly if there ever is need. Now that we are going to add DMA
traffic test driver (in subsequent patches) this can be useful.
For this reason we modify tb_ring_alloc_rx/tx() so that they accept
RING_FLAG_E2E and configure the hardware ring accordingly. The RX side
also requires passing TX HopID (e2e_tx_hop) used in the credit grant
packets.

Further there was only one user ever.
- Android's loadfont, busybox and console-tools only ever use OP_GET
and OP_SET
- fbset documentation only mentions the kernel cmdline font: option,
not anything else.
- systemd used OP_COPY before release 232 published in Nov 2016
Now unfortunately the crucial report seems to have gone down with
gmane, and the commit message doesn't say much. But the pull request
hints at OP_COPY being broken
https://github.com/systemd/systemd/pull/3651
So in other words, this never worked, and the only project which
foolishly every tried to use it, realized that rather quickly too.
Instead of trying to fix security issues here on dead code by adding
missing checks, fix the entire thing by removing the functionality.
Note that systemd code using the OP_COPY function ignored the return
value, so it doesn't matter what we're doing here really - just in
case a lone server somewhere happens to be extremely unlucky and
running an affected old version of systemd. The relevant code from
font_copy_to_all_vcs() in systemd was:
/* copy font from active VT, where the font was uploaded to */
cfo.op = KD_FONT_OP_COPY;
cfo.height = vcs.v_active-1; /* tty1 == index 0 */
(void) ioctl(vcfd, KDFONTOP, &cfo);
Note this just disables the ioctl, garbage collecting the now unused
callbacks is left for -next.

This series adds read_iter support for seq_file, and uses those for

[ Side note: Christoph initially had a scripted "move everything over"
patch, which looks fine, but I personally would prefer us to actively
discourage splice() on random files. So this does just the minimal
basic core set of proc file op conversions.
For completeness, and in case people care, that script was
sed -i -e 's/\.proc_read\(\s*=\s*\)seq_read/\.proc_read_iter\1seq_read_iter/g'
but I'll wait and see if somebody has a strong argument for using
splice on random small /proc files before I'd run it on the whole

Gratian managed to trigger the BUG_ON(!newowner) in fixup_pi_state_owner().
This is one possible chain of events leading to this:
Task Prio Operation
T1 120 lock(F)
T2 120 lock(F) -> blocks (top waiter)
T3 50 (RT) lock(F) -> boosts T1 and blocks (new top waiter)
XX timeout/ -> wakes T2
signal
T1 50 unlock(F) -> wakes T3 (rtmutex->owner == NULL, waiter bit is set)
T2 120 cleanup -> try_to_take_mutex() fails because T3 is the top waiter
and the lower priority T2 cannot steal the lock.
-> fixup_pi_state_owner() sees newowner == NULL -> BUG_ON()
The comment states that this is invalid and rt_mutex_real_owner() must
return a non NULL owner when the trylock failed, but in case of a queued
and woken up waiter rt_mutex_real_owner() == NULL is a valid transient
state. The higher priority waiter has simply not yet managed to take over
the rtmutex.
The BUG_ON() is therefore wrong and this is just another retry condition in
fixup_pi_state_owner().
Drop the locks, so that T3 can make progress, and then try the fixup again.
Gratian provided a great analysis, traces and a reproducer. The analysis is
to the point, but it confused the hell out of that tglx dude who had to
page in all the futex horrors again. Condensed version is above.

As shown through runtime testing, the "filename" allocation is not
always freed in perf_event_parse_addr_filter().
There are three possible ways that this could happen:
- It could be allocated twice on subsequent iterations through the loop,
- or leaked on the success path,
- or on the failure path.
Clean up the code flow to make it obvious that 'filename' is always
freed in the reallocation path and in the two return paths as well.
We rely on the fact that kfree(NULL) is NOP and filename is initialized
with NULL.
This fixes the leak. No other side effects expected.
