mlxsw: Query number of modules from firmware
Vadim says:
The patchset adds support for a new field "num_of_modules" of Management
General Peripheral Information Register (MGPIR), providing the maximum
number of QSFP modules, which can be supported by the system.
It allows to obtain the number of QSFP modules directly from this field,
as a static data, instead of old method of getting this info through
"network port to QSFP module" mapping. With the old method, in case of
port dynamic re-configuration some modules can logically "disappear" as
a result of port split operations, which can cause some modules to
appear missing.
Such scenario can happen on a system equipped with a BMC card, while PCI
chip driver at host CPU side can perform some ports "split" or "unsplit"
operations, while BMC side I2C chip driver reads the "port-to-module"
mapping.
Add common API for FW "minor" and "subminor" versions validation and
share it between PCI and I2C based drivers.
Add FW version validation for "minimal" driver, because use of new field
"num_of_modules" in MGPIR register is not backward compatible.

This set adds trace events related to TLS offload and basic MIB stats
for TLS.
First patch contains the TLS offload related trace points. Those are
helpful in troubleshooting offload issues, especially around the
resync paths.
Second patch adds a tracepoint to the fastpath of device offload,
it's separated out in case there will be objections to adding
fast path tracepoints. Again, it's quite useful for debugging
offload issues.
Next four patches add MIB statistics. The statistics are implemented
as per-cpu per-netns counters. Since there are currently no fast path
statistics we could move to atomic variables. Per-CPU seem more common.
Most basic statistics are number of created and live sessions, broken
out to offloaded and non-offloaded. Users seem to like those a lot.
Next there is a statistic for decryption errors. These are primarily
useful for device offload debug, in normal deployments decryption
errors should not be common.
Last but not least a counter for device RX resync.

Merge branch 'readdir' (readdir speedup and sanity checking)
This makes getdents() and getdents64() do sanity checking on the
pathname that it gives to user space. And to mitigate the performance
impact of that, it first cleans up the way it does the user copying, so
that the code avoids doing the SMAP/PAN updates between each part of the
dirent structure write.
I really wanted to do this during the merge window, but didn't have
time. The conversion of filldir to unsafe_put_user() is something I've
had around for years now in a private branch, but the extra pathname
checking finally made me clean it up to the point where it is mergable.
It's worth noting that the filename validity checking really should be a
bit smarter: it would be much better to delay the error reporting until
the end of the readdir, so that non-corrupted filenames are still
returned. But that involves bigger changes, so let's see if anybody
actually hits the corrupt directory entry case before worrying about it
further.

Make filldir[64]() verify the directory entry filename is valid
This has been discussed several times, and now filesystem people are
talking about doing it individually at the filesystem layer, so head
that off at the pass and just do it in getdents{64}().
This is partially based on a patch by Jann Horn, but checks for NUL
bytes as well, and somewhat simplified.
There's also commentary about how it might be better if invalid names
due to filesystem corruption don't cause an immediate failure, but only
an error at the end of the readdir(), so that people can still see the
filenames that are ok.
There's also been discussion about just how much POSIX strictly speaking
requires this since it's about filesystem corruption. It's really more
"protect user space from bad behavior" as pointed out by Jann. But
since Eric Biederman looked up the POSIX wording, here it is for context:
"From readdir:
The readdir() function shall return a pointer to a structure
representing the directory entry at the current position in the
directory stream specified by the argument dirp, and position the
directory stream at the next entry. It shall return a null pointer
upon reaching the end of the directory stream. The structure dirent
defined in the <dirent.h> header describes a directory entry.
From definitions:
3.129 Directory Entry (or Link)
An object that associates a filename with a file. Several directory
entries can associate names with the same file.
...
3.169 Filename
A name consisting of 1 to {NAME_MAX} bytes used to name a file. The
characters composing the name may be selected from the set of all
character values excluding the slash character and the null byte. The
filenames dot and dot-dot have special meaning. A filename is
sometimes referred to as a 'pathname component'."
Note that I didn't bother adding the checks to any legacy interfaces
that nobody uses.
Also note that if this ends up being noticeable as a performance
regression, we can fix that to do a much more optimized model that
checks for both NUL and '/' at the same time one word at a time.
We haven't really tended to optimize 'memchr()', and it only checks for
one pattern at a time anyway, and we really _should_ check for NUL too
(but see the comment about "soft errors" in the code about why it
currently only checks for '/')
See the CONFIG_DCACHE_WORD_ACCESS case of hash_name() for how the name
lookup code looks for pathname terminating characters in parallel.

Convert filldir[64]() from __put_user() to unsafe_put_user()
We really should avoid the "__{get,put}_user()" functions entirely,
because they can easily be mis-used and the original intent of being
used for simple direct user accesses no longer holds in a post-SMAP/PAN
world.
Manually optimizing away the user access range check makes no sense any
more, when the range check is generally much cheaper than the "enable
user accesses" code that the __{get,put}_user() functions still need.
So instead of __put_user(), use the unsafe_put_user() interface with
user_access_{begin,end}() that really does generate better code these
days, and which is generally a nicer interface. Under some loads, the
multiple user writes that filldir() does are actually quite noticeable.
This also makes the dirent name copy use unsafe_put_user() with a couple
of macros. We do not want to make function calls with SMAP/PAN
disabled, and the code this generates is quite good when the
architecture uses "asm goto" for unsafe_put_user() like x86 does.
Note that this doesn't bother with the legacy cases. Nobody should use
them anyway, so performance doesn't really matter there.

kheaders: make headers archive reproducible
In commit 43d8ce9d65a5 ("Provide in-kernel headers to make
extending kernel easier") a new mechanism was introduced, for kernels
>=5.2, which embeds the kernel headers in the kernel image or a module
and exposes them in procfs for use by userland tools.
The archive containing the header files has nondeterminism caused by
header files metadata. This patch normalizes the metadata and utilizes
KBUILD_BUILD_TIMESTAMP if provided and otherwise falls back to the
default behaviour.
In commit f7b101d33046 ("kheaders: Move from proc to sysfs") it was

scripts/setlocalversion: clear local variable to make it work for sh
Geert Uytterhoeven reports a strange side-effect of commit 858805b336be
("kbuild: add $(BASH) to run scripts with bash-extension"), which
inserts the contents of a localversion file in the build directory twice.
[Steps to Reproduce]
$ echo bar > localversion
$ mkdir build
$ cd build/
$ echo foo > localversion
$ make -s -f ../Makefile defconfig include/config/kernel.release
$ cat include/config/kernel.release
5.4.0-rc1foofoobar
This comes down to the behavior change of local variables.
The 'man sh' on my Ubuntu machine, where sh is an alias to dash,
explains as follows:
When a variable is made local, it inherits the initial value and
exported and readonly flags from the variable with the same name
in the surrounding scope, if there is one. Otherwise, the variable
is initially unset.
[Test Code]
foo ()
{
local res
echo "res: $res"
}
res=1
foo
[Result]
$ sh test.sh
res: 1
$ bash test.sh
res:
So, scripts/setlocalversion correctly works only for bash in spite of
its hashbang being #!/bin/sh. Nobody had noticed it before because
CONFIG_SHELL was previously set to bash almost all the time.
Now that CONFIG_SHELL is set to sh, we must write portable and correct
code. I gave the Fixes tag to the commit that uncovered the issue.
Clear the variable 'res' in collect_files() to make it work for sh
(and it also works on distributions where sh is an alias to bash).

namespace: fix namespace.pl script to support relative paths
The namespace.pl script does not work properly if objtree is not set to
an absolute path. The do_nm function is run from within the find
function, which changes directories.
Because of this, appending objtree, $File::Find::dir, and $source, will
return a path which is not valid from the current directory.
This used to work when objtree was set to an absolute path when using
"make namespacecheck". It appears to have not worked when calling
./scripts/namespace.pl directly.
This behavior was changed in 7e1c04779efd ("kbuild: Use relative path

Rather than fixing the Makefile to set objtree to an absolute path, just
fix namespace.pl to work when srctree and objtree are relative. Also fix
the script to use an absolute path for these by default.
Use the File::Spec module for this purpose. It's been part of perl
5 since 5.005.
The curdir() function is used to get the current directory when the
objtree and srctree aren't set in the environment.
rel2abs() is used to convert possibly relative objtree and srctree
environment variables to absolute paths.
Finally, the catfile() function is used instead of string appending
paths together, since this is more robust when joining paths together.

====================
Fix regression with AR8035 speed downgrade
The following series attempts to address an issue spotted by tinywrkb
with the AR8035 on the Cubox-i2 in a situation where the PHY downgrades
the negotiated link.
This is version 2, not much has changed other than rebasing on the
current net tree. Changes have happend to patch 2 due to conflicts,
so I dropped Andrew's reviewed-by. Minor context changes to patch 4
which I don't consider important enough to warrant dropping the
reviewed-by.
Before commit 5502b218e001 ("net: phy: use phy_resolve_aneg_linkmode in
genphy_read_status"), we would read not only the link partner's
advertisement, but also our own advertisement from the PHY registers,
and use both to derive the PHYs current link mode. This works when the
AR8035 downgrades the speed, because it appears that the AR8035 clears
link mode bits in the advertisement registers as part of the downgrade.
Commentary: what is not yet known is whether the AR8035 restores the
advertisement register when the link goes down to the
previous state.
However, since the above referenced commit, we no longer use the PHYs
advertisement registers, instead converting the link partner's
advertisement to the ethtool link mode array, and combine that with
phylib's cached version of our advertisement - which is not updated on
speed downgrade.
This results in phylib disagreeing with the actual operating mode of
the PHY.
Commentary: I wonder how many more PHY drivers are broken by this
commit, but have yet to be discovered.
The obvious way to address this would be to disable the downgrade
feature, and indeed this does fix the problem in tinywrkb's case - his
link partner instead downgrades the speed by reducing its
advertisement, resulting in phylib correctly evaluating a slower speed.
However, it has a serious drawback - the gigabit control register (MII
register 9) appears to become read only. It seems the only way to
update the register is to re-enable the downgrade feature, reset the
PHY, changing register 9, disable the downgrade feature, and reset the
PHY again.
This series attempts to address the problem using a different approach,
similar to the approach taken with Marvell PHYs. The AR8031, AR8033
and AR8035 have a PHY-Specific Status register which reports the
actual operating mode of the PHY - both speed and duplex. This
register correctly reports the operating mode irrespective of whether
autoneg is enabled or not. We use this register to fill in phylib's
speed and duplex parameters.
In detail:
Patch 1 fixes a bug where writing to register 9 does not update
phylib's advertisement mask in the same way that writing register 4
does; this looks like an omission from when gigabit PHY support came
into being.
Patch 2 seperates the generic phylib code which reads the link partners
advertisement from the PHY, so that we can re-use this in the Atheros
PHY driver.
Patch 3 seperates the generic phylib pause mode; phylib provides no
help for MAC drivers to ascertain the negotiated pause mode, it merely
copies the link partner's pause mode bits into its own variables.
Commentary: Both the aforementioned Atheros PHYs and Marvell PHYs
provide the resolved pause modes in terms of whether
we should transmit pause frames, or whether we should
allow reception of pause frames. Surely the resolution
of this should be in phylib?
Patch 4 provides the Atheros PHY driver with a private "read_status"
implementation that fills in phylib's speed and duplex settings
depending on the PHY-Specific status register. This ensures that
phylib and the MAC driver match the operating mode that the PHY has
decided to use. Since the register also gives us MDIX status, we
can trivially fill that status in as well.
Note that, although the bits mentioned in this patch for this register
match those in th Marvell PHY driver, and it is located at the same
address, the meaning of other register bits varies between the PHYs.
Therefore, I do not feel that it would be appropriate to make this some
kind of generic function.

addrconf_dad_work is kicked to be scheduled when a device is brought
up. There is a race between addrcond_dad_work getting scheduled and

The latter removes the host route from the inet6_addr as part of
addrconf_ifdown which is run for NETDEV_DOWN. The former attempts
to use the host route in __ipv6_ifa_notify. If the down event removes
the host route due to the race to the rtnl, then the BUG listed above
occurs.
Since the DAD sequence can not be aborted, add a check for the missing
host route in __ipv6_ifa_notify. The only way this should happen is due
to the previously mentioned race. The host route is created when the
address is added to an interface; it is only removed on a down event
where the address is kept. Add a warning if the host route is missing

If the device sent to the relevant peer any ICMP error packet

above BITS_PER_LONG and the redirect packets backoff algorithm
will produce undefined behavior.
Fix the issue using 'n_redirects' to compute the exponential backoff
in ip_rt_send_redirect().
Note that we still clear rate_tokens after a redirect silence period,

net/tls: separate the TLS TOE code out
We have 3 modes of operation of TLS - software, crypto offload
(Mellanox, Netronome) and TCP Offload Engine-based (Chelsio).
The last one takes over the socket, like any TOE would, and
is not really compatible with how we want to do things in the
networking stack.
Confusingly the name of the crypto-only offload mode is TLS_HW,
while TOE-offload related functions use tls_hw_ as their prefix.
Engineers looking to implement offload are also be faced with
TOE artefacts like struct tls_device (while, again,
CONFIG_TLS_DEVICE actually gates the non-TOE offload).
To improve the clarity of the offload code move the TOE code
into new files, and rename the functions and structures
appropriately.
Because TOE-offload takes over the socket, and makes no use of
the TLS infrastructure in the kernel, the rest of the code
(anything beyond the ULP setup handlers) do not have to worry
about the mode == TLS_HW_RECORD case.
The increase in code size is due to duplication of the full
license boilerplate. Unfortunately original author (Dave Watson)
seems unreachable :(

Pull RISC-V fixes from Paul Walmsley:
- Ensure that exclusive-load reservations are terminated after system
call or exception handling. This primarily affects QEMU, which does
