Propagate the resolved link parameters via the mac_link_up() call for
MACs that do not automatically track their PCS state. We propagate the
link parameters via function arguments so that inappropriate members
of struct phylink_link_state can't be accessed, and creating a new

When setting VLANs on DSA switches, the VLAN is added to both the port
concerned as well as the CPU port by dsa_slave_vlan_add(), as well as
any DSA ports. If multiple ports are configured with the same VLAN ID,
this triggers a warning on the CPU and DSA ports.

When configuring a tree of independent bridges, propagating changes
from the upper bridge across a bridge master to the lower bridge
ports brings surprises.
For example, a lower bridge may have vlan filtering enabled. It
may have a vlan interface attached to the bridge master, which may
then be incorporated into another bridge. As soon as the lower
bridge vlan interface is attached to the upper bridge, the lower
bridge has vlan filtering disabled.
This occurs because switchdev recursively applies its changes to
all lower devices no matter what.

Clarify the expected flow control settings operation in the phylink
documentation for each negotiation mode.
Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>

Improve the initial MAC configuration so we get a configuration which
more represents the final operating mode, in particular with respect
to the flow control settings.
We do this by:
1) more fully initialising our phy state, so we can use this as the
initial state for PHY based connections.
2) reading the fixed link state.
3) ensuring that in-band mode has sane pause settings for SGMII vs
802.3z negotiation modes.
In all three cases, we ensure that state->link is false, just in case
any MAC drivers have other ideas by mis-using this member, and we also
take account of manual pause mode configuration at this point.
This avoids MLO_PAUSE_AN being seen in mac_config() when operating in
PHY, fixed mode or inband SGMII mode, thereby giving cleaner semantics
to the pause flags. As a result of this, the pause flags now indicate
in a mode-independent way what is required from a mac_config()
implementation.

Split the application of manually controlled flow control modes from
phylink_resolve_flow(), so that we can use alternative providers of

Remove the ability for ethtool -A to change the pause settings for
fixed links; if this is really required, we can reinstate it later.
Andrew Lunn agrees: "So I think it is safe to not implement ethtool
-A, at least until somebody has a real use case for it."
Lets avoid making things too complex for use cases that aren't being

Add a couple of helpers to resolve negotiated flow control. Two helpers
are provided:
- linkmode_resolve_pause() which takes the link partner and local
advertisements, and decodes whether we should enable TX or RX pause
at the MAC. This is useful outside of phylib, e.g. in phylink.
- phy_get_pause(), which returns the TX/RX enablement status for the
current negotiation results of the PHY.
This allows us to centralise the flow control resolution, rather than
spreading it around.

Move the initialisation of the link partner state earlier, inside
marvell_read_status_page(), so we don't have the same initialisation
scattered amongst the other files. This is in a similar place to
the genphy implementation, so would result in the same behaviour if
a PHY read error occurs.
This allows us to get rid of marvell_read_status_page_fixed(), which
became a pointless wrapper around genphy_read_status_fixed().

The crash is due to NULL dereference at
test_bit(idx, ms->usage->subsection_map);
due to ms->usage = NULL in pfn_section_valid()
With commit d41e2f3bd546 ("mm/hotplug: fix hot remove failure in
SPARSEMEM|!VMEMMAP case") section_mem_map is set to NULL after
depopulate_section_mem(). This was done so that pfn_page() can work
correctly with kernel config that disables SPARSEMEM_VMEMMAP. With that
config pfn_to_page does
__section_mem_map_addr(__sec) + __pfn;
where
static inline struct page *__section_mem_map_addr(struct mem_section *section)
{
unsigned long map = section->section_mem_map;
map &= SECTION_MAP_MASK;
return (struct page *)map;
}
Now with SPASEMEM_VMEMAP enabled, mem_section->usage->subsection_map is
used to check the pfn validity (pfn_valid()). Since section_deactivate
release mem_section->usage if a section is fully deactivated,
pfn_valid() check after a subsection_deactivate cause a kernel crash.
static inline int pfn_valid(unsigned long pfn)
{
...
return early_section(ms) || pfn_section_valid(ms, pfn);
}
where
static inline int pfn_section_valid(struct mem_section *ms, unsigned long pfn)
{
int idx = subsection_map_index(pfn);
return test_bit(idx, ms->usage->subsection_map);
}
Avoid this by clearing SECTION_HAS_MEM_MAP when mem_section->usage is
freed. For architectures like ppc64 where large pages are used for
vmmemap mapping (16MB), a specific vmemmap mapping can cover multiple
sections. Hence before a vmemmap mapping page can be freed, the kernel
needs to make sure there are no valid sections within that mapping.
Clearing the section valid bit before depopulate_section_memap enables
this.

Depending on CONFIG_VMAP_STACK and the THREAD_SIZE / PAGE_SIZE ratio the
space for task stacks can be allocated using __vmalloc_node_range(),
alloc_pages_node() and kmem_cache_alloc_node().
In the first and the second cases page->mem_cgroup pointer is set, but
in the third it's not: memcg membership of a slab page should be
determined using the memcg_from_slab_page() function, which looks at
page->slab_cache->memcg_params.memcg . In this case, using
mod_memcg_page_state() (as in account_kernel_stack()) is incorrect:
page->mem_cgroup pointer is NULL even for pages charged to a non-root
memory cgroup.
It can lead to kernel_stack per-memcg counters permanently showing 0 on
some architectures (depending on the configuration).
In order to fix it, let's introduce a mod_memcg_obj_state() helper,
which takes a pointer to a kernel object as a first argument, uses
mem_cgroup_from_obj() to get a RCU-protected memcg pointer and calls
mod_memcg_state(). It allows to handle all possible configurations
(CONFIG_VMAP_STACK and various THREAD_SIZE/PAGE_SIZE values) without
spilling any memcg/kmem specifics into fork.c .
Note: This is a special version of the patch created for stable
backports. It contains code from the following two patches:
- mm: memcg/slab: introduce mem_cgroup_from_obj()
- mm: fork: fix kernel_stack memcg stats for various stack implementations

This appears to be a mistake in commit faced7e0806cf ("mm: hugetlb
controller for cgroups v2").
Essentially that commit does a hugetlb_cgroup_from_counter assuming that
page_counter_try_charge has initialized counter.
But if that has failed then it seems will not initialize counter, so
hugetlb_cgroup_from_counter(counter) ends up pointing to random memory,
causing kasan to complain.
The solution is to simply use 'h_cg', instead of
hugetlb_cgroup_from_counter(counter), since that is a reference to the
hugetlb_cgroup anyway. After this change kasan ceases to complain.

We see multiple issues with the implementation/interface to compute
whether a memory block can be offlined (exposed via
/sys/devices/system/memory/memoryX/removable) and would like to simplify
it (remove the implementation).
1. It runs basically lockless. While this might be good for performance,
we see possible races with memory offlining that will require at
least some sort of locking to fix.
2. Nowadays, more false positives are possible. No arch-specific checks
are performed that validate if memory offlining will not be denied
right away (and such check will require locking). For example, arm64
won't allow to offline any memory block that was added during boot -
which will imply a very high error rate. Other archs have other
constraints.
3. The interface is inherently racy. E.g., if a memory block is detected
to be removable (and was not a false positive at that time), there is
still no guarantee that offlining will actually succeed. So any
caller already has to deal with false positives.
4. It is unclear which performance benefit this interface actually
provides. The introducing commit 5c755e9fd813 ("memory-hotplug: add
sysfs removable attribute for hotplug memory remove") mentioned
"A user-level agent must be able to identify which sections
of memory are likely to be removable before attempting the
potentially expensive operation."
However, no actual performance comparison was included.
Known users:
- lsmem: Will group memory blocks based on the "removable" property. [1]
- chmem: Indirect user. It has a RANGE mode where one can specify
removable ranges identified via lsmem to be offlined. However,
it also has a "SIZE" mode, which allows a sysadmin to skip the
manual "identify removable blocks" step. [2]
- powerpc-utils: Uses the "removable" attribute to skip some memory
blocks right away when trying to find some to offline+remove.
However, with ballooning enabled, it already skips this
information completely (because it once resulted in many false
negatives). Therefore, the implementation can deal with false
positives properly already. [3]
According to Nathan Fontenot, DLPAR on powerpc is nowadays no longer
driven from userspace via the drmgr command (powerpc-utils). Nowadays
it's managed in the kernel - including onlining/offlining of memory
blocks - triggered by drmgr writing to /sys/kernel/dlpar. So the
affected legacy userspace handling is only active on old kernels. Only
very old versions of drmgr on a new kernel (unlikely) might execute
slower - totally acceptable.
With CONFIG_MEMORY_HOTREMOVE, always indicating "removable" should not
break any user space tool. We implement a very bad heuristic now.
Without CONFIG_MEMORY_HOTREMOVE we cannot offline anything, so report
"not removable" as before.
Original discussion can be found in [4] ("[PATCH RFC v1] mm:
is_mem_section_removable() overhaul").
Other users of is_mem_section_removable() will be removed next, so that
we can remove is_mem_section_removable() completely.

claim_swapfile() currently keeps the inode locked when it is successful,
or the file is already swapfile (with -EBUSY). And, on the other error
cases, it does not lock the inode.
This inconsistency of the lock state and return value is quite confusing
and actually causing a bad unlock balance as below in the "bad_swap"
section of __do_sys_swapon().
This commit fixes this issue by moving the inode_lock() and IS_SWAPFILE
check out of claim_swapfile(). The inode is unlocked in
"bad_swap_unlock_inode" section, so that the inode is ensured to be
unlocked at "bad_swap". Thus, error handling codes after the locking now
jumps to "bad_swap_unlock_inode" instead of "bad_swap".

====================
pull-request: bpf 2020-03-27
The following pull-request contains BPF updates for your *net* tree.
We've added 3 non-merge commits during the last 4 day(s) which contain
a total of 4 files changed, 25 insertions(+), 20 deletions(-).
The main changes are:
1) Explicitly memset the bpf_attr structure on bpf() syscall to avoid
having to rely on compiler to do so. Issues have been noticed on
some compilers with padding and other oddities where the request was
then unexpectedly rejected, from Greg Kroah-Hartman.
2) Sanitize the bpf_struct_ops TCP congestion control name in order to
avoid problematic characters such as whitespaces, from Martin KaFai Lau.

On Android/x86 the module loading infrastructure can't deal with
softdeps. Therefore the check for presence of the Realtek PHY driver
module fails. mdiobus_register() will try to load the PHY driver
module, therefore move the check to after this call and explicitly
check that a dedicated PHY driver is bound to the PHY device.
Fixes: f32593773549 ("r8169: check that Realtek PHY driver module is loaded")

Pull ARM DT and driver fixes from Arnd Bergmann:
"For the devicetree files, there are a total of 20 patches, almost
entirely for 32-bit machines:
- The Allwinner/sun9i r40 SoC dtsi file contains a number of issues,
both for correctness and for style that are addressed in separate
patches. This causes most of the changed lines of the DT updates
this time.
- More Allwinner updates fixing the identification of the security
system on sun8i/A33, a recent regression of the A83t ethernet, and
a few board specific issues on the TBS-A711 macine.
- Several bug fixes for OMAP dts files, most notably fixing the
timings for the NAND flash on the Nokia N900 that regressed a while
ago after the move to configuring them from DT. Some other OMAPs
now set the correct dma limits on the L3 bus, and a regression fix
addresses lost Ethernet on dm814x
- One incorrect setting in the newly added Raspberry Pi Zero W that
may cause issues with the SD card controller.
- A missing property on the bcm2835 firmware node caused incorrect
DMA settings.
- An old bug on the oxnas platform causing spurious interrupts is
finally addressed.
- A regression on the Exynos Midas board broke the OLED panel power
supply.
- The i.MX6 phycore SoM specified the wrong voltage for the SoC, this
is now set to the values from the datasheet.
- Some 64-bit machines use a deprecated string to identify the PSCI
firmware.
There are also several small code fixes addressing mostly serious
issues:
- Fix the sunxi rsb bus access to no longer return incorrect data
when mixing 8 and 16 bit I/O.
- Fix a suspend/resume regression on the OMAP2+ lcdc from a missing
quirk in the ti-sysc driver
- Fix a NULL pointer access from a race in the fsl dpio driver
- Fix a v5.5 regression in the exynos-chipid driver that caused an
invalid error code probing the device on non-exynos platforms
- Fix an out-of-bounds access in the AMD TEE driver"
