net: dsa: fix netdev_priv() dereference before check on non-DSA netdevice events
After the blamed commit, we started doing this dereference for every
NETDEV_CHANGEUPPER and NETDEV_PRECHANGEUPPER event in the system.
static inline struct dsa_port *dsa_user_to_port(const struct net_device *dev)
{
struct dsa_user_priv *p = netdev_priv(dev);
return p->dp;
}
Which is obviously bogus, because not all net_devices have a netdev_priv()
of type struct dsa_user_priv. But struct dsa_user_priv is fairly small,
and p->dp means dereferencing 8 bytes starting with offset 16. Most
drivers allocate that much private memory anyway, making our access not
fault, and we discard the bogus data quickly afterwards, so this wasn't
caught.
But the dummy interface is somewhat special in that it calls
alloc_netdev() with a priv size of 0. So every netdev_priv() dereference
is invalid, and we get this when we emit a NETDEV_PRECHANGEUPPER event
with a VLAN as its new upper:
$ ip link add dummy1 type dummy
$ ip link add link dummy1 name dummy1.100 type vlan id 100

selftests/net/tcp-ao: Use LDLIBS instead of LDFLAGS
The rules to link selftests are:
> $(OUTPUT)/%_ipv4: %.c
> $(LINK.c) $^ $(LDLIBS) -o $@
>
> $(OUTPUT)/%_ipv6: %.c
> $(LINK.c) -DIPV6_TEST $^ $(LDLIBS) -o $@
The intel test robot uses only selftest's Makefile, not the top linux
Makefile:
> make W=1 O=/tmp/kselftest -C tools/testing/selftests
So, $(LINK.c) is determined by environment, rather than by kernel
Makefiles. On my machine (as well as other people that ran tcp-ao
selftests) GNU/Make implicit definition does use $(LDFLAGS):
> [dima@Mindolluin ~]$ make -p -f/dev/null | grep '^LINK.c\>'
> make: *** No targets. Stop.
> LINK.c = $(CC) $(CFLAGS) $(CPPFLAGS) $(LDFLAGS) $(TARGET_ARCH)
But, according to build robot report, it's not the case for them.
While I could just avoid using pre-defined $(LINK.c), it's also used by
selftests/lib.mk by default.
Anyways, according to GNU/Make documentation [1], I should have used
$(LDLIBS) instead of $(LDFLAGS) in the first place, so let's just do it:
> LDFLAGS
> Extra flags to give to compilers when they are supposed to invoke
> the linker, ‘ld’, such as -L. Libraries (-lfoo) should be added
> to the LDLIBS variable instead.
> LDLIBS
> Library flags or names given to compilers when they are supposed
> to invoke the linker, ‘ld’. LOADLIBES is a deprecated (but still
> supported) alternative to LDLIBS. Non-library linker flags, such
> as -L, should go in the LDFLAGS variable.

Networking changes for 6.8.
Core & protocols ---------------- - Analyze and reorganize core networking structs (socks, netdev, netns, mibs) to optimize cacheline consumption and set up build time warnings to safeguard against future header changes. This improves TCP performances with many concurrent connections up to 40%. - Add page-pool netlink-based introspection, exposing the memory usage and recycling stats. This helps indentify bad PP users and possible leaks. - Refine TCP/DCCP source port selection to no longer favor even source port at connect() time when IP_LOCAL_PORT_RANGE is set. This lowers the time taken by connect() for hosts having many active connections to the same destination. - Refactor the TCP bind conflict code, shrinking related socket structs. - Refactor TCP SYN-Cookie handling, as a preparation step to allow arbitrary SYN-Cookie processing via eBPF. - Tune optmem_max for 0-copy usage, increasing the default value to 128KB and namespecifying it. - Allow coalescing for cloned skbs coming from page pools, improving RX performances with some common configurations. - Reduce extension header parsing overhead at GRO time. - Add bridge MDB bulk deletion support, allowing user-space to request the deletion of matching entries. - Reorder nftables struct members, to keep data accessed by the datapath first. - Introduce TC block ports tracking and use. This allows supporting multicast-like behavior at the TC layer. - Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and classifiers (RSVP and tcindex). - More data-race annotations. - Extend the diag interface to dump TCP bound-only sockets. - Conditional notification of events for TC qdisc class and actions. - Support for WPAN dynamic associations with nearby devices, to form a sub-network using a specific PAN ID. - Implement SMCv2.1 virtual ISM device support. - Add support for Batman-avd mulicast packet type. BPF --- - Tons of verifier improvements: - BPF register bounds logic and range support along with a large test suite - log improvements - complete precision tracking support for register spills - track aligned STACK_ZERO cases as imprecise spilled registers. It improves the verifier "instructions processed" metric from single digit to 50-60% for some programs - support for user's global BPF subprogram arguments with few commonly requested annotations for a better developer experience - support tracking of BPF_JNE which helps cases when the compiler transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the like - several fixes - Add initial TX metadata implementation for AF_XDP with support in mlx5 and stmmac drivers. Two types of offloads are supported right now, that is, TX timestamp and TX checksum offload. - Fix kCFI bugs in BPF all forms of indirect calls from BPF into kernel and from kernel into BPF work with CFI enabled. This allows BPF to work with CONFIG_FINEIBT=y. - Change BPF verifier logic to validate global subprograms lazily instead of unconditionally before the main program, so they can be guarded using BPF CO-RE techniques. - Support uid/gid options when mounting bpffs. - Add a new kfunc which acquires the associated cgroup of a task within a specific cgroup v1 hierarchy where the latter is identified by its id. - Extend verifier to allow bpf_refcount_acquire() of a map value field obtained via direct load which is a use-case needed in sched_ext. - Add BPF link_info support for uprobe multi link along with bpftool integration for the latter. - Support for VLAN tag in XDP hints. - Remove deprecated bpfilter kernel leftovers given the project is developed in user-space (https://github.com/facebook/bpfilter). Misc ---- - Support for parellel TC self-tests execution. - Increase MPTCP self-tests coverage. - Updated the bridge documentation, including several so-far undocumented features. - Convert all the net self-tests to run in unique netns, to avoid random failures due to conflict and allow concurrent runs. - Add TCP-AO self-tests. - Add kunit tests for both cfg80211 and mac80211. - Autogenerate Netlink families documentation from YAML spec. - Add yml-gen support for fixed headers and recursive nests, the tool can now generate user-space code for all genetlink families for which we have specs. - A bunch of additional module descriptions fixes. - Catch incorrect freeing of pages belonging to a page pool.

Core & protocols: - Analyze and reorganize core networking structs (socks, netdev, netns, mibs) to optimize cacheline consumption and set up build time warnings to safeguard against future header changes This improves TCP performances with many concurrent connections up to 40% - Add page-pool netlink-based introspection, exposing the memory usage and recycling stats. This helps indentify bad PP users and possible leaks - Refine TCP/DCCP source port selection to no longer favor even source port at connect() time when IP_LOCAL_PORT_RANGE is set. This lowers the time taken by connect() for hosts having many active connections to the same destination - Refactor the TCP bind conflict code, shrinking related socket structs - Refactor TCP SYN-Cookie handling, as a preparation step to allow arbitrary SYN-Cookie processing via eBPF - Tune optmem_max for 0-copy usage, increasing the default value to 128KB and namespecifying it - Allow coalescing for cloned skbs coming from page pools, improving RX performances with some common configurations - Reduce extension header parsing overhead at GRO time - Add bridge MDB bulk deletion support, allowing user-space to request the deletion of matching entries - Reorder nftables struct members, to keep data accessed by the datapath first - Introduce TC block ports tracking and use. This allows supporting multicast-like behavior at the TC layer - Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and classifiers (RSVP and tcindex) - More data-race annotations - Extend the diag interface to dump TCP bound-only sockets - Conditional notification of events for TC qdisc class and actions - Support for WPAN dynamic associations with nearby devices, to form a sub-network using a specific PAN ID - Implement SMCv2.1 virtual ISM device support - Add support for Batman-avd mulicast packet type BPF: - Tons of verifier improvements: - BPF register bounds logic and range support along with a large test suite - log improvements - complete precision tracking support for register spills - track aligned STACK_ZERO cases as imprecise spilled registers. This improves the verifier "instructions processed" metric from single digit to 50-60% for some programs - support for user's global BPF subprogram arguments with few commonly requested annotations for a better developer experience - support tracking of BPF_JNE which helps cases when the compiler transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the like - several fixes - Add initial TX metadata implementation for AF_XDP with support in mlx5 and stmmac drivers. Two types of offloads are supported right now, that is, TX timestamp and TX checksum offload - Fix kCFI bugs in BPF all forms of indirect calls from BPF into kernel and from kernel into BPF work with CFI enabled. This allows BPF to work with CONFIG_FINEIBT=y - Change BPF verifier logic to validate global subprograms lazily instead of unconditionally before the main program, so they can be guarded using BPF CO-RE techniques - Support uid/gid options when mounting bpffs - Add a new kfunc which acquires the associated cgroup of a task within a specific cgroup v1 hierarchy where the latter is identified by its id - Extend verifier to allow bpf_refcount_acquire() of a map value field obtained via direct load which is a use-case needed in sched_ext - Add BPF link_info support for uprobe multi link along with bpftool integration for the latter - Support for VLAN tag in XDP hints - Remove deprecated bpfilter kernel leftovers given the project is developed in user-space (https://github.com/facebook/bpfilter) Misc: - Support for parellel TC self-tests execution - Increase MPTCP self-tests coverage - Updated the bridge documentation, including several so-far undocumented features - Convert all the net self-tests to run in unique netns, to avoid random failures due to conflict and allow concurrent runs - Add TCP-AO self-tests - Add kunit tests for both cfg80211 and mac80211 - Autogenerate Netlink families documentation from YAML spec - Add yml-gen support for fixed headers and recursive nests, the tool can now generate user-space code for all genetlink families for which we have specs - A bunch of additional module descriptions fixes - Catch incorrect freeing of pages belonging to a page pool Driver API: - Rust abstractions for network PHY drivers; do not cover yet the full C API, but already allow implementing functional PHY drivers in rust - Introduce queue and NAPI support in the netdev Netlink interface, allowing complete access to the device <> NAPIs <> queues relationship - Introduce notifications filtering for devlink to allow control application scale to thousands of instances - Improve PHY validation, requesting rate matching information for each ethtool link mode supported by both the PHY and host - Add support for ethtool symmetric-xor RSS hash - ACPI based Wifi band RFI (WBRF) mitigation feature for the AMD platform - Expose pin fractional frequency offset value over new DPLL generic netlink attribute - Convert older drivers to platform remove callback returning void - Add support for PHY package MMD read/write New hardware / drivers: - Ethernet: - Octeon CN10K devices - Broadcom 5760X P7 - Qualcomm SM8550 SoC - Texas Instrument DP83TG720S PHY - Bluetooth: - IMC Networks Bluetooth radio Removed: - WiFi: - libertas 16-bit PCMCIA support - Atmel at76c50x drivers - HostAP ISA/PCMCIA style 802.11b driver - zd1201 802.11b USB dongles - Orinoco ISA/PCMCIA 802.11b driver - Aviator/Raytheon driver - Planet WL3501 driver - RNDIS USB 802.11b driver Driver updates: - Ethernet high-speed NICs: - Intel (100G, ice, idpf): - allow one by one port representors creation and removal - add temperature and clock information reporting - add get/set for ethtool's header split ringparam - add again FW logging - adds support switchdev hardware packet mirroring - iavf: implement symmetric-xor RSS hash - igc: add support for concurrent physical and free-running timers - i40e: increase the allowable descriptors - nVidia/Mellanox: - Preparation for Socket-Direct multi-dev netdev.

s390 updates for 6.8 merge window
- Add machine variable capacity information to /proc/sysinfo. - Limit the waste of page tables and always align vmalloc area size and base address on segment boundary. - Fix a memory leak when an attempt to register interruption sub class (ISC) for the adjunct-processor (AP) guest failed. - Reset response code AP_RESPONSE_INVALID_GISA to understandable by guest AP_RESPONSE_INVALID_ADDRESS in response to a failed interruption sub class (ISC) registration attempt. - Improve reaction to adjunct-processor (AP) AP_RESPONSE_OTHERWISE_CHANGED response code when enabling interrupts on behalf of a guest. - Fix incorrect sysfs 'status' attribute of adjunct-processor (AP) queue device bound to the vfio_ap device driver when the mediated device is attached to a guest, but the queue device is not passed through. - Rework struct ap_card to hold the whole adjunct-processor (AP) card hardware information. As result, all the ugly bit checks are replaced by simple evaluations of the required bit fields. - Improve handling of some weird scenarios between service element (SE) host and SE guest with adjunct-processor (AP) pass-through support. - Change local_ctl_set_bit() and local_ctl_clear_bit() so they return the previous value of the to be changed control register. This is useful if a bit is only changed temporarily and the previous content needs to be restored. - The kernel starts with machine checks disabled and is expected to enable it once trap_init() is called. However the implementation allows machine checks early. Consistently enable it in trap_init() only. - local_mcck_disable() and local_mcck_enable() assume that machine checks are always enabled. Instead implement and use local_mcck_save() and local_mcck_restore() to disable machine checks and restore the previous state. - Modification of floating point control (FPC) register of a traced process using ptrace interface may lead to corruption of the FPC register of the tracing process. Fix this. - kvm_arch_vcpu_ioctl_set_fpu() allows to set the floating point control (FPC) register in vCPU, but may lead to corruption of the FPC register of the host process. Fix this. - Use READ_ONCE() to read a vCPU floating point register value from the memory mapped area. This avoids that, depending on code generation, a different value is tested for validity than the one that is used. - Get rid of test_fp_ctl(), since it is quite subtle to use it correctly. Instead copy a new floating point control register value into its save area and test the validity of the new value when loading it. - Remove superfluous save_fpu_regs() call. - Remove s390 support for ARCH_WANTS_DYNAMIC_TASK_STRUCT. All machines provide the vector facility since many years and the need to make the task structure size dependent on the vector facility does not exist. - Remove the "novx" kernel command line option, as the vector code runs without any problems since many years. - Add the vector facility to the z13 architecture level set (ALS). All hypervisors support the vector facility since many years. This allows compile time optimizations of the kernel. - Get rid of MACHINE_HAS_VX and replace it with cpu_has_vx(). As result, the compiled code will have less runtime checks and less code. - Convert pgste_get_lock() and pgste_set_unlock() ASM inlines to C. - Convert the struct subchannel spinlock from pointer to member. -----BEGIN PGP SIGNATURE----- iI0EABYIADUWIQQrtrZiYVkVzKQcYivNdxKlNrRb8AUCZZxnchccYWdvcmRlZXZA bGludXguaWJtLmNvbQAKCRDNdxKlNrRb8PyGAP9Z0Z1Pm3hPf24M4FgY5uuRqBHo VoiuohOZRGONwifnsgEAmN/3ba/7d/j0iMwpUdUFouiqtwTUihh15wYx1sH2IA8= =F6YD -----END PGP SIGNATURE----- Merge tag 's390-6.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Alexander Gordeev: - Add machine variable capacity information to /proc/sysinfo. - Limit the waste of page tables and always align vmalloc area size and base address on segment boundary. - Fix a memory leak when an attempt to register interruption sub class (ISC) for the adjunct-processor (AP) guest failed. - Reset response code AP_RESPONSE_INVALID_GISA to understandable by guest AP_RESPONSE_INVALID_ADDRESS in response to a failed interruption sub class (ISC) registration attempt. - Improve reaction to adjunct-processor (AP) AP_RESPONSE_OTHERWISE_CHANGED response code when enabling interrupts on behalf of a guest. - Fix incorrect sysfs 'status' attribute of adjunct-processor (AP) queue device bound to the vfio_ap device driver when the mediated device is attached to a guest, but the queue device is not passed through. - Rework struct ap_card to hold the whole adjunct-processor (AP) card hardware information.

asm-generic cleanups for 6.8
A series from Baoquan He cleans up the asm-generic/io.h to remove the ioremap_uc() definition from everything except x86, which still needs it for pre-PAT systems. This series notably contains a patch from Jiaxun Yang that converts MIPS to use asm-generic/io.h like every other architecture does, enabling future cleanups. Some of my own patches fix -Wmissing-prototype warnings in architecture specific code across several architectures. This is now needed as the warning is enabled by default. There are still some remaining warnings in minor platforms, but the series should catch most of the widely used ones make them more consistent with one another. David McKay fixes a bug in __generic_cmpxchg_local() when this is used on 64-bit architectures. This could currently only affect parisc64 and sparc64. Additional cleanups address from Linus Walleij, Uwe Kleine-König, Thomas Huth, and Kefeng Wang help reduce unnecessary inconsistencies between architectures. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmWeak8ACgkQYKtH/8kJ UidSiQ/+LL1WTO9d3Zx5HI0GGGjaIYpYs6jUNSf9Y5GPQiOrvjfEWj7CU11/4vxl GlQRpRyncYm8Eiz0Qu+aNxZFiiMah8Uful75yfbX8P1L4EPTbAYNDjkyNJrTjIAK jPK4sl8awIrapOeFUz++PsEj22R/4Is4f0mo+CqoCkL5RKlHe5oFdXzcwjmds4yK CvU6Ldn+M7FZ3EItMdjXaB3D3HS9uictFiO5JByZY8p+IcqgNRI/iHNnZIMsltJ+ XjDi0DG+x4jCj6teElSchw7AofE4OcNSP3xbR1PLKv6+xBLGYaAGZhNuPTz88eV/ Gj0loDQrrR5McGUfDBRHK9zN2Jd0O/FKnfh9kLOt1FLFyGPvC78Q/2HkpVCjbBr2 Pr1aqhLDHA+tGNSsThsV8RUa8/tiEnxAki43tfBFS3SEKhtQsTm2g1z4miwbE3p0 BJIrSgTqrP/SBq7a9z/thPrkzdZcNuA9FUETTbaMeUlJS51n1V9E5A1t7sOG7jaI vV/gbuR6FjvD49mTyQiOSCt3V4ygRqgN1Q+C4QM8WLqq2keUq0AhGodquv8F78in J3x2j2r27lHY7jKf8B0dua/JXAsF20u8qD6yDQ9ymkjt/MWhGXBgK0jpT7RTIuMS e2jmTywUVD4UohAcx3inkOojUhIJ5KDB0I4Pzv4zWcHNbyFNKcY= =4VQl -----END PGP SIGNATURE----- Merge tag 'asm-generic-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull asm-generic cleanups from Arnd Bergmann: "A series from Baoquan He cleans up the asm-generic/io.h to remove the ioremap_uc() definition from everything except x86, which still needs it for pre-PAT systems.

sysctl-6.8-rc1
To help make the move of sysctls out of kernel/sysctl.c not incur a size penalty sysctl has been changed to allow us to not require the sentinel, the final empty element on the sysctl array. Joel Granados has been doing all this work. On the v6.6 kernel we got the major infrastructure changes required to support this. For v6.7 we had all arch/ and drivers/ modified to remove the sentinel. For v6.8-rc1 we get a few more updates for fs/ directory only. The kernel/ directory is left but we'll save that for v6.9-rc1 as those patches are still being reviewed. After that we then can expect also the removal of the no longer needed check for procname == NULL. Let us recap the purpose of this work: - this helps reduce the overall build time size of the kernel and run time memory consumed by the kernel by about ~64 bytes per array - the extra 64-byte penalty is no longer inncurred now when we move sysctls out from kernel/sysctl.c to their own files Thomas Weißschuh also sent a few cleanups, for v6.9-rc1 we expect to see further work by Thomas Weißschuh with the constificatin of the struct ctl_table. Due to Joel Granados's work, and to help bring in new blood, I have suggested for him to become a maintainer and he's accepted. So for v6.9-rc1 I look forward to seeing him sent you a pull request for further sysctl changes. This also removes Iurii Zaikin as a maintainer as he has moved on to other projects and has had no time to help at all. -----BEGIN PGP SIGNATURE----- iQJGBAABCgAwFiEENnNq2KuOejlQLZofziMdCjCSiKcFAmWdWDESHG1jZ3JvZkBr ZXJuZWwub3JnAAoJEM4jHQowkoinjJAP/jTNNoyzWisvrrvmXqR5txFGLOE+wW6x Xv9avuiM+DTHsH/wK8CkXEivwDqYNAZEHU7NEcolS5bJX/ddSRwN9b5aSVlCrUdX Ab4rXmpeSCNFp9zNszWJsDuBKIqjvsKw7qGleGtgZ2qAUHbbH30VROLWCggaee50 wU3icDLdwkasxrcMXy4Sq5dT5wYC4j/QelqBGIkYPT14Arl1im5zqPZ95gmO/s/6 mdicTAmq+hhAUfUBJBXRKtsvxY6CItxe55Q4fjpncLUJLHUw+VPVNoBKFWJlBwlh LO3liKFfakPSkil4/en+/+zuMByd0JBkIzIJa+Kk5kjpbHRhK0RkmU4+Y5G5spWN jjLfiv6RxInNaZ8EWQBMfjE95A7PmYDQ4TOH08+OvzdDIi6B0BB5tBGQpG9BnyXk YsLg1Uo4CwE/vn1/a9w0rhadjUInvmAryhb/uSJYFz/lmApLm2JUpY3/KstwGetb z+HmLstJb24Djkr6pH8DcjhzRBHeWQ5p0b4/6B+v1HqAUuEhdbyw1F2GrDywyF3R h/UOAaKLm1+ffdA246o9TejKiDU96qEzzXMaCzPKyestaRZuiyuYEMDhYbvtsMV5 zIdMJj5HQ+U1KHDv4IN99DEj7+/vjE3f4Sjo+POFpQeQ8/d+fxpFNqXVv449dgnb 6xEkkxsR0ElM =2qBt -----END PGP SIGNATURE----- Merge tag 'sysctl-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux Pull sysctl updates from Luis Chamberlain: "To help make the move of sysctls out of kernel/sysctl.c not incur a size penalty sysctl has been changed to allow us to not require the sentinel, the final empty element on the sysctl array.

header cleanups for 6.8
The goal is to get sched.h down to a type only header, so the main thing happening in this patchset is splitting out various _types.h headers and dependency fixups, as well as moving some things out of sched.h to better locations. This is prep work for the memory allocation profiling patchset which adds new sched.h interdepencencies. Testing - it's been in -next, and fixes from pretty much all architectures have percolated in - nothing major. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKnAFLkS8Qha+jvQrE6szbY3KbnYFAmWfBwwACgkQE6szbY3K bnZPwBAAmuRojXaeWxi01IPIOehSGDe68vw44PR9glEMZvxdnZuPOdvE4/+245/L bRKU2WBCjBUokUbV9msIShwRkFTZAmEMPNfPAAsFMA+VXeDYHKB+ZRdwTggNAQ+I SG6fZgh5m0HsewCDxU8oqVHkjVq4fXn0cy+aL6xLEd9gu67GoBzX2pDieS2Kvy6j jnyoKTxFwb+LTQgph0P4EIpq5I2umAsdLwdSR8EJ+8e9NiNvMo1pI00Lx/ntAnFZ JftWUJcMy3TQ5u1GkyfQN9y/yThX1bZK5GvmHS9SJ2Dkacaus5d+xaKCHtRuFS1I 7C6b8PsNgRczUMumBXus44HdlNfNs1yU3lvVxFvBIPE1qC9pYRHrkWIXXIocXLLC oxTEJ6B2G3BQZVQgLIA4fOaxMVhmvKffi/aEZLi9vN9VVosd1a6XNKI6KbyRnXFp GSs9qDqszhn5I3GYNlDNQTc/8UsRlhPFgS6nS0By6QnvxtGi9QkU2tBRBsXvqwCy cLoCYIhc2tvugHvld70dz26umiJ4rnmxGlobStNoigDvIKAIUt1UmIdr1so8P8eH xehnL9ZcOX6xnANDL0AqMFFHV6I58CJynhFdUoXfVQf/DWLGX48mpi9LVNsYBzsI CAwVOAQ0UjGrpdWmJ9ueY/ABYqg9vRjzaDEXQ+MhAYO55CLaVsg= =3tyT -----END PGP SIGNATURE----- Merge tag 'header_cleanup-2024-01-10' of https://evilpiepirate.org/git/bcachefs Pull header cleanups from Kent Overstreet: "The goal is to get sched.h down to a type only header, so the main thing happening in this patchset is splitting out various _types.h headers and dependency fixups, as well as moving some things out of sched.h to better locations.

bcachefs updates for 6.8:
- btree write buffer rewrite: instead of adding keys to the btree write buffer at transaction commit time, we know journal them with a different journal entry type and copy them from the journal to the write buffer just prior to journal write. This reduces the number of atomic operations on shared cachelines in the transaction commit path and is a signicant performance improvement on some workloads: multithreaded 4k random writes went from ~650k iops to ~850k iops. - Bring back optimistic spinning for six locks: the new implementation doesn't use osq locks; instead we add to the lock waitlist as normal, and then spin on the lock_acquired bit in the waitlist entry, _not_ the lock itself. - BCH_IOCTL_DEV_USAGE_V2, which allows for new data types - BCH_IOCTL_OFFLINE_FSCK, which runs the kernel implementation of fsck but without mounting: useful for transparently using the kernel version of fsck from 'bcachefs fsck' when the kernel version is a better match for the on disk filesystem. - BCH_IOCTL_ONLINE_FSCK: online fsck. Not all passes are supported yet, but the passes that are supported are fully featured - errors may be corrected as normal. The new ioctls use the new 'thread_with_file' abstraction for kicking off a kthread that's tied to a file descriptor returned to userspace via the ioctl. - btree_paths within a btree_trans are now dynamically growable, instead of being limited to 64. This is important for the check_directory_structure phase of fsck, and also fixes some issues we were having with btree path overflow in the reflink btree. - Trigger refactoring; prep work for the upcoming disk space accounting rewrite - Numerous bugfixes :) -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKnAFLkS8Qha+jvQrE6szbY3KbnYFAmWe8PUACgkQE6szbY3K bnYw6g/9GAXfIGasTZZwK2XEr36RYtEFYMwd/m9V1ET0DH6d/MFH9G7tTYl52AQ4 k9cDFb0d2qdtNk2Rlml1lHFrxMzkp2Q7j9S4YcETrE+/Dir8ODVcJXrGeNTCMGmz B+C12mTOpWrzGMrioRgFZjWAnacsY3RP8NFRTT9HIJHO9UCP+xN5y++sX10C5Gwv 7UVWTaUwjkgdYWkR8RCKGXuG5cNNlRp4Y0eeK2XruG1iI9VAilir1glcD/YMOY8M vECQzmf2ZLGFS/tpnmqVhNbNwVWpTQMYassvKaisWNHLDUgskOoF8YfoYSH27t7F GBb1154O2ga6ea866677FDeNVlg386mGCTUy2xOhMpDL3zW+/Is+8MdfJI4MJP5R EwcjHnn2bk0C2kULbAohw0gnU42FulfvsLNnrfxCeygmZrDoOOCL1HpvnBG4vskc Fp6NK83l974QnyLdPsjr1yB2d2pgb+uMP1v76IukQi0IjNSAyvwSa5nloPTHRzpC j6e2cFpdtX+6vEu6KngXVKTblSEnwhVBTaTR37Lr8PX1sZqFS/+mjRDgg3HZa/GI u0fC0mQyVL9KjDs5LJGpTc/qs8J4mpoS5+dfzn38MI76dFxd5TYZKWVfILTrOtDF ugDnoLkMuYFdueKI2M3YzxXyaA7HBT+7McAdENuJJzJnEuSAZs0= =JvA2 -----END PGP SIGNATURE----- Merge tag 'bcachefs-2024-01-10' of https://evilpiepirate.org/git/bcachefs Pull bcachefs updates from Kent Overstreet: - btree write buffer rewrite: instead of adding keys to the btree write buffer at transaction commit time, we now journal them with a different journal entry type and copy them from the journal to the write buffer just prior to journal write.

keys, dns: Fix size check of V1 server-list header
Fix the size check added to dns_resolver_preparse() for the V1 server-list
header so that it doesn't give EINVAL if the size supplied is the same as
the size of the header struct (which should be valid).
This can be tested with:
echo -n -e '\0\0\01\xff\0\0' | keyctl padd dns_resolver desc @p
which will give "add_key: Invalid argument" without this fix.

Hi,
Just a couple fixes and no new features. I've been reviewing and testing TPM patches for encrypted and integrity protected commuinications [1] but they did not made yet to this release. This was also first release I tested with my still heavily in-development test suite for linux integrity [2]. I'm refining this at the moment to run keyutils test suite, which could be potentially also run by a Gitlab runner for keyutis repository.

ext4: fix inconsistent between segment fstrim and full fstrim
Suppose we issue two FITRIM ioctls for ranges [0,15] and [16,31] with mininum length of trimmed range set to 8 blocks. If we have say a range of blocks 10-22 free, this range will not be trimmed because it straddles the boundary of the two FITRIM ranges and neither part is big enough. This is a bit surprising to some users that call FITRIM on smaller ranges of blocks to limit impact on the system. Also XFS trims all free space extents that overlap with the specified range so we are inconsistent among filesystems. Let's change ext4_try_to_trim_range() to consider for trimming the whole free space extent that straddles the end of specified range, not just the part of it within the range.

ext4: fallback to complex scan if aligned scan doesn't work
Currently in case the goal length is a multiple of stripe size we use ext4_mb_scan_aligned() to find the stripe size aligned physical blocks. In case we are not able to find any, we again go back to calling ext4_mb_choose_next_group() to search for a different suitable block group. However, since the linear search always begins from the start, most of the times we end up with the same BG and the cycle continues. With large fliesystems, the CPU can be stuck in this loop for hours which can slow down the whole system. Hence, until we figure out a better way to continue the search (rather than starting from beginning) in ext4_mb_choose_next_group(), lets just fallback to ext4_mb_complex_scan_group() in case aligned scan fails, as it is much more likely to find the needed blocks.

ext4: allow for the last group to be marked as trimmed
The ext4 filesystem tracks the trim status of blocks at the group
level. When an entire group has been trimmed then it is marked as
such and subsequent trim invocations with the same minimum trim size
will not be attempted on that group unless it is marked as able to be
trimmed again such as when a block is freed.
Currently the last group can't be marked as trimmed due to incorrect
logic in ext4_last_grp_cluster(). ext4_last_grp_cluster() is supposed
to return the zero based index of the last cluster in a group. This is
then used by ext4_try_to_trim_range() to determine if the trim
operation spans the entire group and as such if the trim status of the
group should be recorded.
ext4_last_grp_cluster() takes a 0 based group index, thus the valid
values for grp are 0..(ext4_get_groups_count - 1). Any group index
less than (ext4_get_groups_count - 1) is not the last group and must
have EXT4_CLUSTERS_PER_GROUP(sb) clusters. For the last group we need
to calculate the number of clusters based on the number of blocks in
the group. Finally subtract 1 from the number of clusters as zero
based indexing is expected. Rearrange the function slightly to make
it clear what we are calculating and returning.
Reproducer:
// Create file system where the last group has fewer blocks than
// blocks per group
$ mkfs.ext4 -b 4096 -g 8192 /dev/nvme0n1 8191
$ mount /dev/nvme0n1 /mnt
Before Patch:
$ fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed
// Group not marked as trimmed so second invocation still discards blocks
$ fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed
After Patch:
fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed
// Group marked as trimmed so second invocation DOESN'T discard any blocks
fstrim -v /mnt
/mnt: 0 B (0 bytes) trimmed

NFSD 6.8 Release Notes
The bulk of the patches for this release are clean-ups and minor bug fixes. There is one significant revert to mention: support for RDMA Read operations in the server's RPC-over-RDMA transport implementation has been fixed so it waits for Read completion in a way that avoids tying up an nfsd thread. This prevents a possible DoS vector if an RPC-over-RDMA client should become unresponsive during RDMA Read operations.

This could occasionally cause the rotation algorithm to drop straight through, give a 'successful' result without actually emitting any RPC calls, leaving the reply buffer in an undefined state. Instead, detach the probe results into a separate struct and allocate a new one each time we start probing and update the pointer to it. Probes are also sent in order of address preference to try and improve the chance that the preferred one will complete first. - Fix server rotation so that it uses configurable address preferences across on the probes that have completed so far than ranking them by RTT as the latter doesn't necessarily give the best route. The preference list can be altered by writing into /proc/net/afs/addr_prefs. - Fix the handling of Read-Only (and Backup) volume callbacks as there is one per volume, not one per file, so if someone performs a command that, say, offlines the volume but doesn't change it, when it comes back online we don't spam the server with a status fetch for every vnode we're using. Instead, check the Creation timestamp in the VolSync record when prompted by a callback break. - Handle volume regression (ie. a RW volume being restored from a backup) by scrubbing all cache data for that volume. This is detected from the VolSync creation timestamp. - Adjust abort handling and abort -> error mapping to match better with what other AFS clients do. - Fix offline and busy volume state handling as they only apply to individual server instances and not entire volumes and the rotation algorithm should go and look at other servers if available. Also make it sleep briefly before each retry if all the volume instances are unavailable" * tag 'afs-fix-rotation-20240105' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: (40 commits) afs: trace: Log afs_make_call(), including server address afs: Fix offline and busy message emission afs: Fix fileserver rotation afs: Overhaul invalidation handling to better support RO volumes afs: Parse the VolSync record in the reply of a number of RPC ops afs: Don't leave DONTUSE/NEWREPSITE servers out of server list afs: Fix comment in afs_do_lookup() afs: Apply server breaks to mmap'd files in the call processor afs: Move the vnode/volume validity checking code into its own file afs: Defer volume record destruction to a workqueue afs: Make it possible to find the volumes that are using a server afs: Combine the endpoint state bools into a bitmask afs: Keep a record of the current fileserver endpoint state afs: Dispatch vlserver probes in priority order afs: Dispatch fileserver probes in priority order afs: Mark address lists with configured priorities afs: Provide a way to configure address priorities afs: Remove the unimplemented afs_cmp_addr_list() afs: Add some more info to /proc/net/afs/servers rxrpc: Create a procfile to display outstanding client conn bundles ... |
