Fixes for 5.10-rc3:
- Fix an uninitialized struct problem. - Fix an iomap problem zeroing unwritten EOF blocks. - Fix some clumsy error handling when writeback fails on blocksize < pagesize filesystems. - Fix a retry loop not resetting loop variables properly. - Fix scrub flagging rtinherit inodes on a non-rt fs, since the kernel actually does permit that combination. - Fix excessive page cache flushing when unsharing part of a file. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEUzaAxoMeQq6m2jMV+H93GTRKtOsFAl+jWK8ACgkQ+H93GTRK tOuiEQ/+IAEncpqUS1PTSWRlNX7MEQDvlnoLl9ZqhaYrW9pNyz8JzxejubkP/7RA qkI/fgcBIhxOf+mTKguAUsu81we49PmlObWCEb5mfBI2aeoSL/yM4zikOHFNpy0o f4U9++kpKJwrWG6kyvNwYMyT6r74vLW0EO9lhYjxAY6+5KgZL0SuFuRAaADDtWj8 SKIc/dli6qDS3IrnkibQtzFOOcmeOEn0qcWcS4gD7tbUpJlw0M2g88JjBPoT8oTK wRBNrspbAA42YbYqlwmkBQZZwM+XZKLZNcvzzLgQLaQdTKEem2w2pB1j1KvJXsSo ibxhmk1/tGFKtPTmbpm7dUC9ubr7xch6J+GHNwHuaWL2hxBWJzNRVokG1BsbDXcc FW3ilwLFd8CFUXttQqQfhiUx8wfe2eJ1aXEBK5JeHWRwD+egLI9WXFJQzjUUwe+v T+7r+0kS2TL3SXKU5TE+gsuuI5mcJpYvcWVqYPwBxjZW0tIhUzBldpfBYysG3ZAm uhYcw3BHw1ucsjqcSe14CWqA4KnwgfAcKva5AJSLjJBu3wOi1wrFKg/+Wtpo0xA2 yFAqFP5FGW13oqeYtqJy0J79qOw6Po9wl+XnekSiBCEif965KtV+RBMP2/TBG+Pl R+bNvSXlb1QiDNSjiIG2b34RiDNoiV2k+ELxOz3SSbzIxx8gvm4= =MqoT -----END PGP SIGNATURE----- Merge tag 'xfs-5.10-fixes-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux Pull xfs fixes from Darrick Wong: - Fix an uninitialized struct problem - Fix an iomap problem zeroing unwritten EOF blocks - Fix some clumsy error handling when writeback fails on filesystems with blocksize < pagesize - Fix a retry loop not resetting loop variables properly - Fix scrub flagging rtinherit inodes on a non-rt fs, since the kernel actually does permit that combination - Fix excessive page cache flushing when unsharing part of a file * tag 'xfs-5.10-fixes-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: xfs: only flush the unshared range in xfs_reflink_unshare xfs: fix scrub flagging rtinherit even if there is no rt device xfs: fix missing CoW blocks writeback conversion retry iomap: clean up writeback state logic on writepage error iomap: support partial page discard on writeback block mapping failure xfs: flush new eof page on truncate to avoid post-eof corruption xfs: set xefi_discard when creating a deferred agfl free log intent item |

Merge branch 'hch' (patches from Christoph)
Merge procfs splice read fixes from Christoph Hellwig:
"Greg reported a problem due to the fact that Android tests use procfs
files to test splice, which stopped working with the changes for
set_fs() removal.
This series adds read_iter support for seq_file, and uses those for
various proc files using seq_file to restore splice read support"
[ 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
kernel. - Linus ]
* emailed patches from Christoph Hellwig <hch@lst.de>:
proc "seq files": switch to ->read_iter
proc "single files": switch to ->read_iter
proc/stat: switch to ->read_iter
proc/cpuinfo: switch to ->read_iter
proc: wire up generic_file_splice_read for iter ops
seq_file: add seq_read_iter

Networking fixes for 5.10-rc3, including fixes from wireless, can,
and netfilter subtrees.
Current release - bugs in new features:
- can: isotp: isotp_rcv_cf(): enable RX timeout handling in
listen-only mode
Previous release - regressions:
- mac80211:
- don't require VHT elements for HE on 2.4 GHz
- fix regression where EAPOL frames were sent in plaintext
- netfilter:
- ipset: Update byte and packet counters regardless of whether
they match
- ip_tunnel: fix over-mtu packet send by allowing fragmenting even
if inner packet has IP_DF (don't fragment) set in its header
(when TUNNEL_DONT_FRAGMENT flag is not set on the tunnel dev)
- net: fec: fix MDIO probing for some FEC hardware blocks
- ip6_tunnel: set inner ipproto before ip6_tnl_encap to un-break
gso support
- sctp: Fix COMM_LOST/CANT_STR_ASSOC err reporting on big-endian
platforms, sparse-related fix used the wrong integer size
Previous release - always broken:
- netfilter: use actual socket sk rather than skb sk when routing
harder
- r8169: work around short packet hw bug on RTL8125 by padding frames
- net: ethernet: ti: cpsw: disable PTPv1 hw timestamping
advertisement, the hardware does not support it
- chelsio/chtls: fix always leaking ctrl_skb and another leak caused
by a race condition
- fix drivers incorrectly writing into skbs on TX:
- cadence: force nonlinear buffers to be cloned
- gianfar: Account for Tx PTP timestamp in the skb headroom
- gianfar: Replace skb_realloc_headroom with skb_cow_head for PTP
- can: flexcan:
- remove FLEXCAN_QUIRK_DISABLE_MECR quirk for LS1021A
- add ECC initialization for VF610 and LX2160A
- flexcan_remove(): disable wakeup completely
- can: fix packet echo functionality:
- peak_canfd: fix echo management when loopback is on
- make sure skbs are not freed in IRQ context in case they need
to be dropped
- always clone the skbs to make sure they have a reference on
the socket, and prevent it from disappearing
- fix real payload length return value for RTR frames
- can: j1939: return failure on bind if netdev is down, rather than
waiting indefinitely
Misc:
- IPv6: reply ICMP error if the first fragment don't include all
headers to improve compliance with RFC 8200

io_uring: properly handle SQPOLL request cancelations
Track if a given task io_uring context contains SQPOLL instances, so we can iterate those for cancelation (and request counts). This ensures that we properly wait on SQPOLL contexts, and find everything that needs canceling. Signed-off-by: Jens Axboe <axboe@kernel.dk> |

iomap: support partial page discard on writeback block mapping failure
iomap writeback mapping failure only calls into ->discard_page() if the current page has not been added to the ioend. Accordingly, the XFS callback assumes a full page discard and invalidation. This is problematic for sub-page block size filesystems where some portion of a page might have been mapped successfully before a failure to map a delalloc block occurs. ->discard_page() is not called in that error scenario and the bio is explicitly failed by iomap via the error return from ->prepare_ioend(). As a result, the filesystem leaks delalloc blocks and corrupts the filesystem block counters. Since XFS is the only user of ->discard_page(), tweak the semantics to invoke the callback unconditionally on mapping errors and provide the file offset that failed to map. Update xfs_discard_page() to discard the corresponding portion of the file and pass the range along to iomap_invalidatepage(). The latter already properly handles both full and sub-page scenarios by not changing any iomap or page state on sub-page invalidations.

can: can_create_echo_skb(): fix echo skb generation: always use skb_clone()
All user space generated SKBs are owned by a socket (unless injected into the
key via AF_PACKET). If a socket is closed, all associated skbs will be cleaned
up.
This leads to a problem when a CAN driver calls can_put_echo_skb() on a
unshared SKB. If the socket is closed prior to the TX complete handler,
can_get_echo_skb() and the subsequent delivering of the echo SKB to all
registered callbacks, a SKB with a refcount of 0 is delivered.
To avoid the problem, in can_get_echo_skb() the original SKB is now always
cloned, regardless of shared SKB or not. If the process exists it can now
safely discard its SKBs, without disturbing the delivery of the echo SKB.
The problem shows up in the j1939 stack, when it clones the incoming skb, which
detects the already 0 refcount.
We can easily reproduce this with following example:
testj1939 -B -r can0: &

mm: always have io_remap_pfn_range() set pgprot_decrypted()
The purpose of io_remap_pfn_range() is to map IO memory, such as a
memory mapped IO exposed through a PCI BAR. IO devices do not
understand encryption, so this memory must always be decrypted.
Automatically call pgprot_decrypted() as part of the generic
implementation.
This fixes a bug where enabling AMD SME causes subsystems, such as RDMA,
using io_remap_pfn_range() to expose BAR pages to user space to fail.
The CPU will encrypt access to those BAR pages instead of passing
unencrypted IO directly to the device.
Places not mapping IO should use remap_pfn_range().

Char/Misc fixes/removals for 5.10-rc2
Here's some small fixes for 5.10-rc2 and a big driver removal. The fixes are for some reported issues in the interconnect and coresight drivers, nothing major. The "big" driver removal is the MIC drivers have been asked to be removed as the hardware never shipped and Intel no longer wants to maintain something that no one can use. This is welcomed by many as the DMA usage of these drivers was "interesting" and the security people were starting to question some issues that were starting to be found in the codebase. Note, one of the subsystems for this driver, the "VOP" code, will probably come back in future kernel versions as it was looking to potentially solve some PCIe virtualization issues that a number of other vendors were wanting to solve. But as-is, this codebase didn't work for anyone else so no actual functionality is being removed. All of these have been in linux-next with no reported issues.

Driver core / Documentation fixes for 5.10-rc2

net/mlx5: Replace zero-length array with flexible-array member
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2].

Power management fixes for 5.10-rc2
- Modify Kconfig to prevent configuring either the "conservative"
or the "ondemand" governor as the default cpufreq governor if
intel_pstate is selected, in which case "schedutil" is the
default choice for the default governor setting (Rafael Wysocki).
- Modify the cpufreq core, intel_pstate and the schedutil governor
to avoid missing updates of the HWP max limit when intel_pstate
operates in the passive mode with HWP enabled (Rafael Wysocki).
- Fix max_cstate module parameter handling in intel_idle for
processor models with C-state tables coming from ACPI (Chen Yu).
- Clean up assorted pieces of power management code (Jackie Zamow,
Tom Rix, Zhang Qilong).

netfilter: nf_tables: missing validation from the abort path
If userspace does not include the trailing end of batch message, then
nfnetlink aborts the transaction. This allows to check that ruleset
updates trigger no errors.
After this patch, invoking this command from the prerouting chain:
# nft -c add rule x y fib saddr . oif type local
fails since oif is not supported there.
This patch fixes the lack of rule validation from the abort/check path
to catch configuration errors such as the one above.
Fixes:

netfilter: use actual socket sk rather than skb sk when routing harder
If netfilter changes the packet mark when mangling, the packet is
rerouted using the route_me_harder set of functions. Prior to this
commit, there's one big difference between route_me_harder and the
ordinary initial routing functions, described in the comment above
__ip_queue_xmit():
/* Note: skb->sk can be different from sk, in case of tunnels */
int __ip_queue_xmit(struct sock *sk, struct sk_buff *skb, struct flowi *fl,
That function goes on to correctly make use of sk->sk_bound_dev_if,
rather than skb->sk->sk_bound_dev_if. And indeed the comment is true: a
tunnel will receive a packet in ndo_start_xmit with an initial skb->sk.
It will make some transformations to that packet, and then it will send
the encapsulated packet out of a *new* socket. That new socket will
basically always have a different sk_bound_dev_if (otherwise there'd be
a routing loop). So for the purposes of routing the encapsulated packet,
the routing information as it pertains to the socket should come from
that socket's sk, rather than the packet's original skb->sk. For that
reason __ip_queue_xmit() and related functions all do the right thing.
One might argue that all tunnels should just call skb_orphan(skb) before
transmitting the encapsulated packet into the new socket. But tunnels do
*not* do this -- and this is wisely avoided in skb_scrub_packet() too --
because features like TSQ rely on skb->destructor() being called when
that buffer space is truely available again. Calling skb_orphan(skb) too
early would result in buffers filling up unnecessarily and accounting
info being all wrong. Instead, additional routing must take into account
the new sk, just as __ip_queue_xmit() notes.
So, this commit addresses the problem by fishing the correct sk out of
state->sk -- it's already set properly in the call to nf_hook() in
__ip_local_out(), which receives the sk as part of its normal
functionality. So we make sure to plumb state->sk through the various
route_me_harder functions, and then make correct use of it following the
example of __ip_queue_xmit().

mac80211: fix kernel-doc markups
Some identifiers have different names between their prototypes
and the kernel-doc markup.
Others need to be fixed, as kernel-doc markups should use this format:
identifier - description
In the specific case of __sta_info_flush(), add a documentation
for sta_info_flush(), as this one is the one used outside
sta_info.c.

fallthrough fixes for Clang for 5.10-rc2
Hi Linus,
Please, pull the following patch that fixes almost 40,000 fall-through
warnings when building Linux 5.10-rc1 with Clang 12.0.0 and this[1]
change reverted. Notice that in order to enable -Wimplicit-fallthrough
for Clang, such change[1] is meant to be reverted at some point. So,
this patch helps to move in that direction.

include: jhash/signal: Fix fall-through warnings for Clang
In preparation to enable -Wimplicit-fallthrough for Clang, explicitly add break statements instead of letting the code fall through to the next case. This patch adds four break statements that, together, fix almost 40,000 warnings when building Linux 5.10-rc1 with Clang 12.0.0 and this[1] change reverted. Notice that in order to enable -Wimplicit-fallthrough for Clang, such change[1] is meant to be reverted at some point. So, this patch helps to move in that direction. Something important to mention is that there is currently a discrepancy between GCC and Clang when dealing with switch fall-through to empty case statements or to cases that only contain a break/continue/return statement[2][3][4]. Now that the -Wimplicit-fallthrough option has been globally enabled[5], any compiler should really warn on missing either a fallthrough annotation or any of the other case-terminating statements (break/continue/return/ goto) when falling through to the next case statement. Making exceptions to this introduces variation in case handling which may continue to lead to bugs, misunderstandings, and a general lack of robustness. The point of enabling options like -Wimplicit-fallthrough is to prevent human error and aid developers in spotting bugs before their code is even built/ submitted/committed, therefore eliminating classes of bugs. So, in order to really accomplish this, we should, and can, move in the direction of addressing any error-prone scenarios and get rid of the unintentional fallthrough bug-class in the kernel, entirely, even if there is some minor redundancy. Better to have explicit case-ending statements than continue to have exceptions where one must guess as to the right result. The compiler will eliminate any actual redundancy. [1] commit |

afs: Fix afs_invalidatepage to adjust the dirty region
Fix afs_invalidatepage() to adjust the dirty region recorded in
page->private when truncating a page. If the dirty region is entirely
removed, then the private data is cleared and the page dirty state is
cleared.
Without this, if the page is truncated and then expanded again by truncate,
zeros from the expanded, but no-longer dirty region may get written back to
the server if the page gets laundered due to a conflicting 3rd-party write.
It mustn't, however, shorten the dirty region of the page if that page is
still mmapped and has been marked dirty by afs_page_mkwrite(), so a flag is
stored in page->private to record this.

afs: Wrap page->private manipulations in inline functions
The afs filesystem uses page->private to store the dirty range within a
page such that in the event of a conflicting 3rd-party write to the server,
we write back just the bits that got changed locally.
However, there are a couple of problems with this:
(1) I need a bit to note if the page might be mapped so that partial
invalidation doesn't shrink the range.
(2) There aren't necessarily sufficient bits to store the entire range of
data altered (say it's a 32-bit system with 64KiB pages or transparent
huge pages are in use).
So wrap the accesses in inline functions so that future commits can change
how this works.
Also move them out of the tracing header into the in-directory header.
There's not really any need for them to be in the tracing header.
