sk->sk_err appears to expect a positive value, a convention that ktls
doesn't always follow and that leads to memory corruption in other code.
For instance,
[kworker]
tls_encrypt_done(..., err=<negative error from crypto request>)
tls_err_abort(.., err)
sk->sk_err = err;
[task]
splice_from_pipe_feed
...
tls_sw_do_sendpage
if (sk->sk_err) {
ret = -sk->sk_err; // ret is positive
splice_from_pipe_feed (continued)
ret = actor(...) // ret is still positive and interpreted as bytes
// written, resulting in underflow of buf->len and
// sd->len, leading to huge buf->offset and bogus
// addresses computed in later calls to actor()
Fix all tls_err_abort() callers to pass a negative error code
consistently and centralize the error-prone sign flip there, throwing in
a warning to catch future misuse and uninlining the function so it
really does only warn once.

While waiting for a carrier to come on one of the netdevices, some
devices will require to take the rtnl lock at some point to fully
initialize all parts of the link.
That's the case for SFP, where the rtnl is taken when a module gets
detected. This prevents mounting an NFS rootfs over an SFP link.
This means that while ipconfig waits for carriers to be detected, no SFP
modules can be detected in the meantime, it's only detected after
ipconfig times out.
This commit releases the rtnl_lock while waiting for the carrier to come
up, and re-takes it to check the for the init device and carrier status.

Add the missing endpoint sanity checks to probe() to avoid division by
zero in mwifiex_write_data_sync() in case a malicious device has broken
descriptors (or when doing descriptor fuzz testing).
Only add checks for the firmware-download boot stage, which require both
command endpoints, for now. The driver looks like it will handle a
missing endpoint during normal operation without oopsing, albeit not
very gracefully as it will try to submit URBs to the default pipe and
fail.
Note that USB core will reject URBs submitted for endpoints with zero
wMaxPacketSize but that drivers doing packet-size calculations still
need to handle this (cf. commit 2548288b4fb0 ("USB: Fix: Don't skip
endpoint descriptors with maxpacket=0")).

Convert mvpp2 to phylink supported_interfaces
This patch series converts mvpp2 to use phylinks supported_interfaces
bitmap to simplify the validate() implementation. The patches:
1) Add the supported interface modes the supported_interfaces bitmap.
2) Removes the checks for the interface type being supported from
the validate callback
3) Removes the now unnecessary checks and call to
phylink_helper_basex_speed() to support switching between
1000base-X and 2500base-X for SFPs
4) Cleans up the resulting validate() code.
(3) becomes possible because when asking the MAC for its complete
support, we walk all supported interfaces which will include 1000base-X
and 2500base-X only if the comphy is present.

After commit 9298e63eafea ("bpf/tests: Add exhaustive tests of ALU
operand magnitudes"), when modprobe test_bpf.ko with JIT on mips64,
there exists segment fault due to the following reason:
[...]
ALU64_MOV_X: all register value magnitudes jited:1
Break instruction in kernel code[#1]
[...]
It seems that the related JIT implementations of some test cases
in test_bpf() have problems. At this moment, I do not care about
the segment fault while I just want to verify the test cases of
tail calls.
Based on the above background and motivation, add the following
module parameter test_suite to the test_bpf.ko:
test_suite=<string>: only the specified test suite will be run, the
string can be "test_bpf", "test_tail_calls" or "test_skb_segment".
If test_suite is not specified, but test_id, test_name or test_range
is specified, set 'test_bpf' as the default test suite. This is useful
to only test the corresponding test suite when specifying the valid
test_suite string.
Any invalid test suite will result in -EINVAL being returned and no
tests being run. If the test_suite is not specified or specified as
empty string, it does not change the current logic, all of the test
cases will be run.
Here are some test results:

When we receive an association response, a significant amount
of time might have passed since we sent the corresponding
association request (mac80211 will wait up to 500ms for the TX

the time event is touched only when we send the assoc request,
so it might not have much time remaining, more easily causing

Trying to convert from one firmware data representation to the
next version is getting tedious and error-prone, and doesn't
lend itself well to new APIs being added. Additionally, the
version 11 of the API as defined in the driver doesn't even
exist in the firmware.
Instead of converting to a newer firmware version of the data,
convert to an internal representation. This takes a bit more
space because the TKIP/AES counters etc. must be kept twice,
their representation is different and we don't know which of
the ones it is until later, but this is just a temporary use
of memory, and the code is clearer this way.
