net: openvswitch: fix TTL decrement action netlink message format
Currently, the openvswitch module is not accepting the correctly formated
netlink message for the TTL decrement action. For both setting and getting
the dec_ttl action, the actions should be nested in the
OVS_DEC_TTL_ATTR_ACTION attribute as mentioned in the openvswitch.h uapi.
When the original patch was sent, it was tested with a private OVS userspace
implementation. This implementation was unfortunately not upstreamed and
reviewed, hence an erroneous version of this patch was sent out.
Leaving the patch as-is would cause problems as the kernel module could
interpret additional attributes as actions and vice-versa, due to the
actions not being encapsulated/nested within the actual attribute, but
being concatinated after it.

net/tls: Protect from calling tls_dev_del for TLS RX twice
tls_device_offload_cleanup_rx doesn't clear tls_ctx->netdev after
calling tls_dev_del if TLX TX offload is also enabled. Clearing
tls_ctx->netdev gets postponed until tls_device_gc_task. It leaves a
time frame when tls_device_down may get called and call tls_dev_del for
RX one extra time, confusing the driver, which may lead to a crash.
This patch corrects this racy behavior by adding a flag to prevent
tls_device_down from calling tls_dev_del the second time.

devlink: Fix reload stats structure
Fix reload stats structure exposed to the user. Change stats structure
hierarchy to have the reload action as a parent of the stat entry and
then stat entry includes value per limit. This will also help to avoid
string concatenation on iproute2 output.
Reload stats structure before this fix:
"stats": {
"reload": {
"driver_reinit": 2,
"fw_activate": 1,
"fw_activate_no_reset": 0
}
}
After this fix:
"stats": {
"reload": {
"driver_reinit": {

},
"fw_activate": {
"unspecified": 1,
"no_reset": 0

tcp: fix race condition when creating child sockets from syncookies
When the TCP stack is in SYN flood mode, the server child socket is created from the SYN cookie received in a TCP packet with the ACK flag set. The child socket is created when the server receives the first TCP packet with a valid SYN cookie from the client. Usually, this packet corresponds to the final step of the TCP 3-way handshake, the ACK packet. But is also possible to receive a valid SYN cookie from the first TCP data packet sent by the client, and thus create a child socket from that SYN cookie. Since a client socket is ready to send data as soon as it receives the SYN+ACK packet from the server, the client can send the ACK packet (sent by the TCP stack code), and the first data packet (sent by the userspace program) almost at the same time, and thus the server will equally receive the two TCP packets with valid SYN cookies almost at the same instant. When such event happens, the TCP stack code has a race condition that occurs between the momement a lookup is done to the established connections hashtable to check for the existence of a connection for the same client, and the moment that the child socket is added to the established connections hashtable. As a consequence, this race condition can lead to a situation where we add two child sockets to the established connections hashtable and deliver two sockets to the userspace program to the same client. This patch fixes the race condition by checking if an existing child socket exists for the same client when we are adding the second child socket to the established connections socket. If an existing child socket exists, we drop the packet and discard the second child socket to the same client.

A couple of scheduler fixes:

mm: fix readahead_page_batch for retry entries
Both btrfs and fuse have reported faults caused by seeing a retry entry
instead of the page they were looking for. This was caused by a missing
check in the iterator.
As can be seen in the below panic log, the accessing 0x402 causes a
panic. In the xarray.h, 0x402 means RETRY_ENTRY.

mm: fix phys_to_target_node() and memory_add_physaddr_to_nid() exports
The core-mm has a default __weak implementation of phys_to_target_node()
to mirror the weak definition of memory_add_physaddr_to_nid(). That
symbol is exported for modules. However, while the export in
mm/memory_hotplug.c exported the symbol in the configuration cases of:
CONFIG_NUMA_KEEP_MEMINFO=y
CONFIG_MEMORY_HOTPLUG=y
...and:
CONFIG_NUMA_KEEP_MEMINFO=n
CONFIG_MEMORY_HOTPLUG=y
...it failed to export the symbol in the case of:
CONFIG_NUMA_KEEP_MEMINFO=y
CONFIG_MEMORY_HOTPLUG=n
Not only is that broken, but Christoph points out that the kernel should
not be exporting any __weak symbol, which means that
memory_add_physaddr_to_nid() example that phys_to_target_node() copied
is broken too.
Rework the definition of phys_to_target_node() and
memory_add_physaddr_to_nid() to not require weak symbols. Move to the
common arch override design-pattern of an asm header defining a symbol
to replace the default implementation.
The only common header that all memory_add_physaddr_to_nid() producing
architectures implement is asm/sparsemem.h. In fact, powerpc already
defines its memory_add_physaddr_to_nid() helper in sparsemem.h.
Double-down on that observation and define phys_to_target_node() where
necessary in asm/sparsemem.h. An alternate consideration that was
discarded was to put this override in asm/numa.h, but that entangles
with the definition of MAX_NUMNODES relative to the inclusion of
linux/nodemask.h, and requires powerpc to grow a new header.
The dependency on NUMA_KEEP_MEMINFO for DEV_DAX_HMEM_DEVICES is invalid
now that the symbol is properly exported / stubbed in all combinations
of CONFIG_NUMA_KEEP_MEMINFO and CONFIG_MEMORY_HOTPLUG.

compiler-clang: remove version check for BPF Tracing
bpftrace parses the kernel headers and uses Clang under the hood.
Remove the version check when __BPF_TRACING__ is defined (as bpftrace
does) so that this tool can continue to parse kernel headers, even with
older clang sources.

spi: Fixes for v5.10
This is a relatively large set of fixes, the bulk of it being a series from Lukas Wunner which fixes confusion with the lifetime of driver data allocated along with the SPI controller structure that's been created as part of the conversion to devm APIs. The simplest fix, explained in detail in Lukas' commit message, is to move to a devm_ function for allocation of the controller and hence driver data in order to push the free of that after anything tries to reference the driver data in the remove path. This results in a relatively large diff due to the addition of a new function but isn't particularly complex. There's also a fix from sven van Asbroeck which fixes yet more fallout from the conflicts between the various different places one can configure the polarity of GPIOs in modern systems. Otherwise everything is fairly small and driver specific. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl+2qqsACgkQJNaLcl1U h9DN/gf+P85QtRuWq8hGt9cEywwvPXdYEifxlJuevO+RIzyrI7y6hc2AqmQ/ek2Q kRU39CVLzrm+P8GRX/K6wL8sSQmBVJSt25aWwYKiygidh4eFqmDKC5y/yQY+VIoW /MvFpdFOENDbAjRRK3l5x9BdwXsNPadjl7Ts2FGyjsBOOEWdXf9fApXju7oVHGki oDc35Z5o1DdwTdTD5B/uKP2VmevbrEmBceGZttaSUjyO4kJ9ehe+kJ1DuBu9QrTN GDu/J7oijbtYYfRi6DeMjVfUvvNK9c+6TQay91j0c6ZNW5TuYkZ0XS1vbpjwshQg wWPxA+uQ4YelNgRQ4H+PhzOKo0zv4A== =oG9R -----END PGP SIGNATURE----- Merge tag 'spi-fix-v5.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi Pull spi fixes from Mark Brown: "This is a relatively large set of fixes, the bulk of it being a series from Lukas Wunner which fixes confusion with the lifetime of driver data allocated along with the SPI controller structure that's been created as part of the conversion to devm APIs.

iommu/vt-d: Avoid panic if iommu init fails in tboot system
"intel_iommu=off" command line is used to disable iommu but iommu is force
enabled in a tboot system for security reason.
However for better performance on high speed network device, a new option
"intel_iommu=tboot_noforce" is introduced to disable the force on.
By default kernel should panic if iommu init fail in tboot for security
reason, but it's unnecessory if we use "intel_iommu=tboot_noforce,off".
Fix the code setting force_on and move intel_iommu_tboot_noforce
from tboot code to intel iommu code.

request, we return it, together with its record serial number. Before this
fix, we mistakenly returned the serial number of the current record
instead.

Problem is that boosted entities (Priority Inheritance) use static DEADLINE parameters of the top priority waiter. However, there might be cases where top waiter could be a non-DEADLINE entity that is currently boosted by a DEADLINE entity from a different lock chain (i.e., nested priority chains involving entities of non-DEADLINE classes). In this case, top waiter static DEADLINE parameters could be null (initialized to 0 at fork()) and replenish_dl_entity() would hit a BUG(). Fix this by keeping track of the original donor and using its parameters when a task is boosted.

scsi: libiscsi: Fix NOP race condition
iSCSI NOPs are sometimes "lost", mistakenly sent to the user-land iscsid daemon instead of handled in the kernel, as they should be, resulting in a message from the daemon like: iscsid: Got nop in, but kernel supports nop handling. This can occur because of the new forward- and back-locks, and the fact that an iSCSI NOP response can occur before processing of the NOP send is complete. This can result in "conn->ping_task" being NULL in iscsi_nop_out_rsp(), when the pointer is actually in the process of being set. To work around this, we add a new state to the "ping_task" pointer. In addition to NULL (not assigned) and a pointer (assigned), we add the state "being set", which is signaled with an INVALID pointer (using "-1").

PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter
In many case, we need to check return value of pm_runtime_get_sync, but it brings a trouble to the usage counter processing. Many callers forget to decrease the usage counter when it failed, which could resulted in reference leak. It has been discussed a lot[0][1]. So we add a function to deal with the usage counter for better coding.

arch: pgtable: define MAX_POSSIBLE_PHYSMEM_BITS where needed
Stefan Agner reported a bug when using zsram on 32-bit Arm machines with RAM above the 4GB address boundary: Unable to handle kernel NULL pointer dereference at virtual address 00000000 pgd = a27bd01c [00000000] *pgd=236a0003, *pmd=1ffa64003 Internal error: Oops: 207 [#1] SMP ARM Modules linked in: mdio_bcm_unimac(+) brcmfmac cfg80211 brcmutil raspberrypi_hwmon hci_uart crc32_arm_ce bcm2711_thermal phy_generic genet CPU: 0 PID: 123 Comm: mkfs.ext4 Not tainted 5.9.6 #1 Hardware name: BCM2711 PC is at zs_map_object+0x94/0x338 LR is at zram_bvec_rw.constprop.0+0x330/0xa64 pc : [<c0602b38>] lr : [<c0bda6a0>] psr: 60000013 sp : e376bbe0 ip : 00000000 fp : c1e2921c r10: 00000002 r9 : c1dda730 r8 : 00000000 r7 : e8ff7a00 r6 : 00000000 r5 : 02f9ffa0 r4 : e3710000 r3 : 000fdffe r2 : c1e0ce80 r1 : ebf979a0 r0 : 00000000 Flags: nZCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment user Control: 30c5383d Table: 235c2a80 DAC: fffffffd Process mkfs.ext4 (pid: 123, stack limit = 0x495a22e6) Stack: (0xe376bbe0 to 0xe376c000) As it turns out, zsram needs to know the maximum memory size, which is defined in MAX_PHYSMEM_BITS when CONFIG_SPARSEMEM is set, or in MAX_POSSIBLE_PHYSMEM_BITS on the x86 architecture. The same problem will be hit on all 32-bit architectures that have a physical address space larger than 4GB and happen to not enable sparsemem and include asm/sparsemem.h from asm/pgtable.h. After the initial discussion, I suggested just always defining MAX_POSSIBLE_PHYSMEM_BITS whenever CONFIG_PHYS_ADDR_T_64BIT is set, or provoking a build error otherwise. This addresses all configurations that can currently have this runtime bug, but leaves all other configurations unchanged. I looked up the possible number of bits in source code and datasheets, here is what I found: - on ARC, CONFIG_ARC_HAS_PAE40 controls whether 32 or 40 bits are used - on ARM, CONFIG_LPAE enables 40 bit addressing, without it we never support more than 32 bits, even though supersections in theory allow up to 40 bits as well. - on MIPS, some MIPS32r1 or later chips support 36 bits, and MIPS32r5 XPA supports up to 60 bits in theory, but 40 bits are more than anyone will ever ship - On PowerPC, there are three different implementations of 36 bit addressing, but 32-bit is used without CONFIG_PTE_64BIT - On RISC-V, the normal page table format can support 34 bit addressing. There is no highmem support on RISC-V, so anything above 2GB is unused, but it might be useful to eventually support CONFIG_ZRAM for high pages. Fixes: |

A set of fixes for perf:
- A set of commits which reduce the stack usage of various perf event handling functions which allocated large data structs on stack causing stack overflows in the worst case. - Use the proper mechanism for detecting soft interrupts in the recursion protection. - Make the resursion protection simpler and more robust. - Simplify the scheduling of event groups to make the code more robust and prepare for fixing the issues vs. scheduling of exclusive event groups. - Prevent event multiplexing and rotation for exclusive event groups - Correct the perf event attribute exclusive semantics to take pinned events, e.g. the PMU watchdog, into account - Make the anythread filtering conditional for Intel's generic PMU counters as it is not longer guaranteed to be supported on newer CPUs. Check the corresponding CPUID leaf to make sure. - Fixup a duplicate initialization in an array which was probably cause by the usual copy & paste - forgot to edit mishap. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAl+xIi0THHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYofixD/4+4gc8DhOmAkMrN0Z9tiW8ebgMKmb9 wZRkMr5Osi0GzLJOPZ6SdY6jd0A3rMN/sW6P1DT6pDtcty4bKFoW5VZBuUDIAhel BC4C93L3y1En/GEZu1GTy3LvsBwLBQTOoY4goDjbdAbk60S/0RTHOGyQsRsOQFe6 fVs3iXozAFuaR6I6N3dlxuJAE51zvr8MyBWaUoByNDB//1+lLNW+JfClaAOG1oXx qZIg/niatBVGzSGgKNRUyh3g8G1HJtabsA/NZ4PH8ZHuYABfmj4lmmUPR77ICLfV wMITEBG7eaktB8EqM9hvaoOZLA5kpXHO2JbCFSs4c4x11mlC8g7QMV3poCw33YoN a5TmT1A3muri1riy1/Ee9lXACOq7/tf2+Xfn9o6dvDdBwd6s5pzlhLGR8gILp2lF 2bcg3IwYvHT/Kiurb/WGNpbCqQIPJpcUcfs3tNBCCtKegahUQNnGjxN3NVo9RCit zfL6xIJ8eZiYnsxXx4NKm744AukWiql3aRNgRkOdBP5WC68xt6VLcxG1YZKUoDhy jRSOCD/DuPSMSvAAgN7S8OWlPsKWBxVxxWYV+K8FpwhgzbQ3WbS3UDiYkhgjeOxu OlM692oWpllKvQWlvYthr2Be6oPCRRi1vvADNNbTKzgHk5i61bwympsGl1EZx3Pz 2ROp7NJFRESnqw== =FzCf -----END PGP SIGNATURE----- Merge tag 'perf-urgent-2020-11-15' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull perf fixes from Thomas Gleixner: "A set of fixes for perf: - A set of commits which reduce the stack usage of various perf event handling functions which allocated large data structs on stack causing stack overflows in the worst case - Use the proper mechanism for detecting soft interrupts in the recursion protection - Make the resursion protection simpler and more robust - Simplify the scheduling of event groups to make the code more robust and prepare for fixing the issues vs. scheduling of exclusive event groups - Prevent event multiplexing and rotation for exclusive event groups - Correct the perf event attribute exclusive semantics to take pinned events, e.g. the PMU watchdog, into account - Make the anythread filtering conditional for Intel's generic PMU counters as it is not longer guaranteed to be supported on newer CPUs.

ip_tunnels: Set tunnel option flag when tunnel metadata is present
Currently, we may set the tunnel option flag when the size of metadata
is zero. For example, we set TUNNEL_GENEVE_OPT in the receive function
no matter the geneve option is present or not. As this may result in
issues on the tunnel flags consumers, this patch fixes the issue.

A very long time ago, a hack was added to the vfs fs freeze protection code to work around lockdep complaints about XFS, which would try to run a transaction (which requires intwrite protection) to finalize an xfs freeze (by which time the vfs had already taken intwrite). Fast forward a few years, and XFS fixed the recursive intwrite problem on its own, and the hack became unnecessary. Fast forward almost a decade, and latent bugs in the code converting this hack from freeze flags to freeze locks combine with lockdep bugs to make this reproduce frequently enough to notice page faults racing with freeze. Since the hack is unnecessary and causes thread race errors, just get rid of it completely. Making this kind of vfs change midway through a cycle makes me nervous, but a large enough number of the usual VFS/ext4/XFS/btrfs suspects have said this looks good and solves a real problem vector. And once that removal is done, __sb_start_write is now simple enough that it becomes possible to refactor the function into smaller, simpler static inline helpers in linux/fs.h. The cleanup is straightforward. Summary: - Finally remove the "convert to trylock" weirdness in the fs freezer code. It was necessary 10 years ago to deal with nested transactions in XFS, but we've long since removed that; and now this is causing subtle race conditions when lockdep goes offline and sb_start_* aren't prepared to retry a trylock failure. - Minor cleanups of the sb_start_* fs freeze helpers" * tag 'vfs-5.10-fixes-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: vfs: move __sb_{start,end}_write* to fs.h vfs: separate __sb_start_write into blocking and non-blocking helpers vfs: remove lockdep bogosity in __sb_start_write |
