perf/x86/intel: Fix spurious NMI on fixed counter
If a user first sample a PEBS event on a fixed counter, then sample a non-PEBS event on the same fixed counter on Icelake, it will trigger spurious NMI. For example: perf record -e 'cycles:p' -a perf record -e 'cycles' -a The error message for spurious NMI: [June 21 15:38] Uhhuh. NMI received for unknown reason 30 on CPU 2. [ +0.000000] Do you have a strange power saving mode enabled? [ +0.000000] Dazed and confused, but trying to continue The bug was introduced by the following commit: commit |

perf/core: Fix exclusive events' grouping
So far, we tried to disallow grouping exclusive events for the fear of
complications they would cause with moving between contexts. Specifically,
moving a software group to a hardware context would violate the exclusivity
rules if both groups contain matching exclusive events.
This attempt was, however, unsuccessful: the check that we have in the
perf_event_open() syscall is both wrong (looks at wrong PMU) and
insufficient (group leader may still be exclusive), as can be illustrated
by running:
$ perf record -e '{intel_pt//,cycles}' uname
$ perf record -e '{cycles,intel_pt//}' uname
ultimately successfully.
Furthermore, we are completely free to trigger the exclusivity violation
by:
perf -e '{cycles,intel_pt//}' -e '{intel_pt//,instructions}'
even though the helpful perf record will not allow that, the ABI will.
The warning later in the perf_event_open() path will also not trigger, because
it's also wrong.
Fix all this by validating the original group before moving, getting rid
of broken safeguards and placing a useful one to perf_install_in_context().

perf/core: Fix race between close() and fork()

Which is a 'fun' confluence of fail; copy_process() doing an unconditional free_task() and not respecting refcounts, and perf having creative locking. In particular: |

f2fs-for-5.3-rc1
In this round, we've introduced native swap file support which can exploit DIO, enhanced existing checkpoint=disable feature with additional mount option to tune the triggering condition, and allowed user to preallocate physical blocks in a pinned file which will be useful to avoid f2fs fragmentation in append-only workloads. In addition, we've fixed subtle quota corruption issue. Enhancement: - add swap file support which uses DIO - allocate blocks for pinned file - allow SSR and mount option to enhance checkpoint=disable - enhance IPU IOs - add more sanity checks such as memory boundary access Bug fix: - quota corruption in very corner case of error-injected SPO case - fix root_reserved on remount and some wrong counts - add missing fsck flag Some patches were also introduced to clean up ambiguous i_flags and debugging messages codes. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAl0mlKIACgkQQBSofoJI UNI2Ow//e4QxinKVdgA6F2wx0CkdSreqfzQbA1t+6pcWgzCgLfj4dpOuSp8Yu1NT aG6YFfUxjtUNN8D85WqJ+6qKt0gFBoxjQXDvvbxLFB9Xoa2XqzFrHW8xenSRHppj V63Yye5Z+Qgss65hTktgHMWSi4mUWRq76t1lFBprXm41uC036rIQCSYioztcLQCN fFi2xfkFHf7vIIg6ZrCy22wNSCWL9X6dzKftIZ6LSz+jkPGEard1D/OUYLMMQ4YG b5DS0LEWbudn1vwALPPXwTHgZuG12W581MsHUsu2FIyenGGTk7EIZfNBN6cGfIMk NsEMnanFvXp7ZYP6HQnZlSkoBRIkD2JpYh7bFxTklw4H09GJxYFksed8uqNoDRog GPcNZjKSm0wCUHe2awOhF9kRXMFnwIR7m4DNOQHH1MYmpp3ponGsbfYy3J/qLS5y Smh8pcbsttDMQ0NaWZznby2bSEv9k9R9CoqE5sKCNDnh6Ky8WjK8x6xt3wrPG6h8 jI7venvHvJbFpxAmnKDzflZrlGj95pg0j0DAk07ql/9i8YPfRrlBKv8jOo+7aRWC jIO70URGDO6R/o5XdRqx6u8DOE1JPVP+6XzsT6MdDtBlxE+TbcTPRt3RzEgmo1d3 CI0jq0IRDTDZJITmQoQKCS85OZDyaAe2iHUPwSjCEuDex5lynuY= =S2ZS -----END PGP SIGNATURE----- Merge tag 'f2fs-for-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've introduced native swap file support which can exploit DIO, enhanced existing checkpoint=disable feature with additional mount option to tune the triggering condition, and allowed user to preallocate physical blocks in a pinned file which will be useful to avoid f2fs fragmentation in append-only workloads.

- Claim maintainership of various loose xfs documentation and header
files.
- Use struct bio directly for log buffer IOs instead of struct xfs_buf.
- Reduce log item boilerplate code requirements.
- Merge log item code spread across too many files.
- Further distinguish between log item commits and cancellations.
- Various small cleanups to the ag small allocator.
- Support cgroup-aware writeback
- libxfs refactoring for mkfs cleanup

- Fix a memory allocation miscalculation in the new log bio code
- Fix bisection problems
- Fix a crash in ioend processing caused by tripping over freeing of
preallocated transactions
- Split out a generic inode walk mechanism from the bulkstat code, hook
up all the internal users to use the walking code, then clean up
bulkstat to serve only the bulkstat ioctls.
- Add a multithreaded iwalk implementation to speed up quotacheck on
fast storage with many CPUs.
- Remove unnecessary return values in logging teardown functions.
- Supplement the bstat and inogrp structures with new bulkstat and
inumbers structures that have all the fields we need for v5
filesystem features and none of the padding problems of their
predecessors.
- Wire up new ioctls that use the new structures with a much simpler
bulk_ireq structure at the head instead of the pointerhappy mess we
had before.
- Enable userspace to constrain bulkstat returns to a single AG or a
single special inode so that we can phase out a lot of geometry
guesswork in userspace.
- Reduce memory consumption and zeroing overhead in extended attribute
scrub code.
- Fix some behavioral regressions in the new bulkstat backend code.
- Fix some behavioral regressions in the new log bio code.

for the FS_IOC_SETFLAGS and FS_IOC_FSSETXATTR ioctl implementations.
The goal here is to reduce the amount of behaviorial variance between
the filesystems where those ioctls originated (ext2 and XFS,
respectively) and everybody else.
- Standardize parameter checking for the SETFLAGS and FSSETXATTR
ioctls (which were the file attribute setters for ext4 and xfs and
have now been hoisted to the vfs)
- Only allow the DAX flag to be set on files and directories"
* tag 'vfs-fix-ioctl-checking-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
vfs: only allow FSSETXATTR to set DAX flag on files and dirs
vfs: teach vfs_ioc_fssetxattr_check to check extent size hints

cxgb4: reduce kernel stack usage in cudbg_collect_mem_region()
The cudbg_collect_mem_region() and cudbg_read_fw_mem() both use several
hundred kilobytes of kernel stack space. One gets inlined into the other,
which causes the stack usage to be combined beyond the warning limit
when building with clang:
drivers/net/ethernet/chelsio/cxgb4/cudbg_lib.c:1057:12: error: stack frame size of 1244 bytes in function 'cudbg_collect_mem_region' [-Werror,-Wframe-larger-than=]
Restructuring cudbg_collect_mem_region() lets clang do the same
optimization that gcc does and reuse the stack slots as it can
see that the large variables are never used together.
A better fix might be to avoid using cudbg_meminfo on the stack
altogether, but that requires a larger rewrite.
Fixes:

tipc: ensure head->lock is initialised
tipc_named_node_up() creates a skb list. It passes the list to tipc_node_xmit() which has some code paths that can call skb_queue_purge() which relies on the list->lock being initialised. The spin_lock is only needed if the messages end up on the receive path but when the list is created in tipc_named_node_up() we don't necessarily know if it is going to end up there. Once all the skb list users are updated in tipc it will then be possible to update them to use the unlocked variants of the skb list functions and initialise the lock when we know the message will follow the receive path.

The patches ensure that flows that should not be supported are not (incorrectly) offloaded. These include rules that match on layer 3 and/or 4 data without specified ethernet or ip protocol fields. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

nfp: flower: ensure ip protocol is specified for L4 matches
Flower rules on the NFP firmware are able to match on an IP protocol
field. When parsing rules in the driver, unknown IP protocols are only
rejected when further matches are to be carried out on layer 4 fields, as
the firmware will not be able to extract such fields from packets.
L4 protocol dissectors such as FLOW_DISSECTOR_KEY_PORTS are only parsed if
an IP protocol is specified. This leaves a loophole whereby a rule that
attempts to match on transport layer information such as port numbers but
does not explicitly give an IP protocol type can be incorrectly offloaded
(in this case with wildcard port numbers matches).
Fix this by rejecting the offload of flows that attempt to match on L4
information, not only when matching on an unknown IP protocol type, but
also when the protocol is wildcarded.

nfp: flower: fix ethernet check on match fields
NFP firmware does not explicitly match on an ethernet type field. Rather,
each rule has a bitmask of match fields that can be used to infer the
ethernet type.
Currently, if a flower rule contains an unknown ethernet type, a check is
carried out for matches on other fields of the packet. If matches on
layer 3 or 4 are found, then the offload is rejected as firmware will not
be able to extract these fields from a packet with an ethernet type it
does not currently understand.
However, if a rule contains an unknown ethernet type without any L3 (or
above) matches then this will effectively be offloaded as a rule with a
wildcarded ethertype. This can lead to misclassifications on the firmware.
Fix this issue by rejecting all flower rules that specify a match on an
unknown ethernet type.
Further ensure correct offloads by moving the 'L3 and above' check to any
rule that does not specify an ethernet type and rejecting rules with
further matches. This means that we can still offload rules with a
wildcarded ethertype if they only match on L2 fields but will prevent
rules which match on further fields that we cannot be sure if the firmware
will be able to extract.

net/mlx5e: Provide cb_list pointer when setting up tc block on rep
Recent refactoring of tc block offloads infrastructure introduced new
flow_block_cb_setup_simple() method intended to be used as unified way for
all drivers to register offload callbacks. However, commit that actually
extended all users (drivers) with block cb list and provided it to
flow_block infra missed mlx5 en_rep. This leads to following NULL-pointer
dereference when creating Qdisc:

net: phy: make exported variables non-static
The variables phy_basic_ports_array, phy_fibre_port_array and
phy_all_ports_features_array are declared static and marked
EXPORT_SYMBOL_GPL(), which is at best an odd combination.
Because the variables were decided to be a part of API, this commit
removes the static attributes and adds the declarations to the header.

Introduce new function tcf_block_non_null_shared() that verifies block
pointer before dereferencing it to obtain index. Use the function in
tc_indr_block_ing_cmd() to prevent NULL pointer dereference.

davinci_cpdma: don't cast dma_addr_t to pointer
dma_addr_t may be 64-bit wide on 32-bit architectures, so it is not
valid to cast between it and a pointer:
drivers/net/ethernet/ti/davinci_cpdma.c: In function 'cpdma_chan_submit_si':
drivers/net/ethernet/ti/davinci_cpdma.c:1047:12: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
drivers/net/ethernet/ti/davinci_cpdma.c: In function 'cpdma_chan_idle_submit_mapped':
drivers/net/ethernet/ti/davinci_cpdma.c:1114:12: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
drivers/net/ethernet/ti/davinci_cpdma.c: In function 'cpdma_chan_submit_mapped':
drivers/net/ethernet/ti/davinci_cpdma.c:1164:12: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
Solve this by using two separate members in 'struct submit_info'.
Since this avoids the use of the 'flag' member, the structure does
not even grow in typical configurations.

net: openvswitch: do not update max_headroom if new headroom is equal to old headroom
When a vport is deleted, the maximum headroom size would be changed. If the vport which has the largest headroom is deleted, the new max_headroom would be set. But, if the new headroom size is equal to the old headroom size, updating routine is unnecessary.
