2023-11-23ksmbd: move oplock handling after unlock parent dirNamjae Jeon
ksmbd should process secound parallel smb2 create request during waiting oplock break ack. parent lock range that is too large in smb2_open() causes smb2_open() to be serialized. Move the oplock handling to the bottom of smb2_open() and make it called after parent unlock. This fixes the failure of smb2.lease.breaking1 testcase.

xfstests generic/002 test fail when enabling smb2 leases feature. This test create hard link file, but removeal failed. ci has a file open count to count file open through the smb client, but in the case of hard link files, The allocation of ci per inode cause incorrectly open count for file deletion.

2023-11-23btrfs: make error messages more clear when getting a chunk mapFilipe Manana
When getting a chunk map, at btrfs_get_chunk_map(), we do some sanity checks to verify we found a chunk map and that map found covers the logical address the caller passed in. However the messages aren't very clear in the sense that don't mention the issue is with a chunk map and one of them prints the 'length' argument as if it were the end offset of the requested range (while the in the string format we use %llu-%llu which suggests a range, and the second %llu-%llu is actually a range for the chunk map). So improve these two details in the error messages.

2023-11-23btrfs: fix off-by-one when checking chunk map includes logical addressFilipe Manana
At btrfs_get_chunk_map() we get the extent map for the chunk that contains the given logical address stored in the 'logical' argument. Then we do sanity checks to verify the extent map contains the logical address. One of these checks verifies if the extent map covers a range with an end offset behind the target logical address - however this check has an off-by-one error since it will consider an extent map whose start offset plus its length matches the target logical address as inclusive, while the fact is that the last byte it covers is behind the target logical address (by 1). So fix this condition by using '<=' rather than '<' when comparing the extent map's "start + length" against the target logical address.

In btrfs_ref_tree_mod(), when !parent 're' was allocated through kmalloc(). In the following code, if an error occurs, the execution will be redirected to 'out' or 'out_unlock' and the function will be exited. However, on some of the paths, 're' are not deallocated and may lead to memory leaks. For example: lookup_block_entry() for 'be' returns NULL, the out label will be invoked. During that flow ref and 'ra' are freed but not 're', which can potentially lead to a memory leak.

2023-11-23btrfs: add dmesg output for first mount and last unmount of a filesystemQu Wenruo
There is a feature request to add dmesg output when unmounting a btrfs. There are several alternative methods to do the same thing, but with their own problems: - Use eBPF to watch btrfs_put_super()/open_ctree() Not end user friendly, they have to dip their head into the source code. - Watch for directory /sys/fs/<uuid>/ This is way more simple, but still requires some simple device -> uuid lookups. And a script needs to use inotify to watch /sys/fs/. Compared to all these, directly outputting the information into dmesg would be the most simple one, with both device and UUID included. And since we're here, also add the output when mounting a filesystem for the first time for parity. A more fine grained monitoring of subvolume mounts should be done by another layer, like audit. Now mounting a btrfs with all default mkfs options would look like this: [81.906566] BTRFS info (device dm-8): first mount of filesystem 633b5c16-afe3-4b79-b195-138fe145e4f2 [81.907494] BTRFS info (device dm-8): using crc32c (crc32c-intel) checksum algorithm [81.908258] BTRFS info (device dm-8): using free space tree [81.912644] BTRFS info (device dm-8): auto enabling async discard [81.913277] BTRFS info (device dm-8): checking UUID tree [91.668256] BTRFS info (device dm-8): last unmount of filesystem 633b5c16-afe3-4b79-b195-138fe145e4f2 CC: stable@vger.kernel.org # 5.4+ Link: https://github.com/kdave/btrfs-progs/issues/689 Reviewed-by: Anand Jain <anand.jain@oracle.com> Signed-off-by: Qu Wenruo <wqu@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> [ update changelog ] Signed-off-by: David Sterba <dsterba@suse.com>

Commit 2b3486bc2d23 ("bpf: Introduce device-bound XDP programs") introduced device-bound programs by largely reusing existing offloading infrastructure. This changed the semantics of 'prog->aux->offload' a bit. Now, it's non-NULL for both offloaded and device-bound programs. Instead of looking at 'prog->aux->offload' let's call bpf_prog_is_offloaded which should be true iff the program is offloaded and not merely device-bound.

2023-11-23arm64: add dependency between vmlinuz.efi and ImageMasahiro Yamada
A common issue in Makefile is a race in parallel building. You need to be careful to prevent multiple threads from writing to the same file simultaneously. Commit 3939f3345050 ("ARM: 8418/1: add boot image dependencies to not generate invalid images") addressed such a bad scenario. A similar symptom occurs with the following command: $ make -j$(nproc) ARCH=arm64 Image vmlinuz.efi [ snip ] SORTTAB vmlinux OBJCOPY arch/arm64/boot/Image OBJCOPY arch/arm64/boot/Image AS arch/arm64/boot/zboot-header.o PAD arch/arm64/boot/vmlinux.bin GZIP arch/arm64/boot/vmlinuz OBJCOPY arch/arm64/boot/vmlinuz.o LD arch/arm64/boot/vmlinuz.efi.elf OBJCOPY arch/arm64/boot/vmlinuz.efi The log "OBJCOPY arch/arm64/boot/Image" is displayed twice. It indicates that two threads simultaneously enter arch/arm64/boot/ and write to arch/arm64/boot/Image. It occasionally leads to a build failure: $ make -j$(nproc) ARCH=arm64 Image vmlinuz.efi [ snip ] SORTTAB vmlinux OBJCOPY arch/arm64/boot/Image PAD arch/arm64/boot/vmlinux.bin truncate: Invalid number: 'arch/arm64/boot/vmlinux.bin' make[2]: *** [drivers/firmware/efi/libstub/Makefile.zboot:13: arch/arm64/boot/vmlinux.bin] Error 1 make[2]: *** Deleting file 'arch/arm64/boot/vmlinux.bin' make[1]: *** [arch/arm64/Makefile:163: vmlinuz.efi] Error 2 make[1]: *** Waiting for unfinished jobs.... make: *** [Makefile:234: __sub-make] Error 2 vmlinuz.efi depends on Image, but such a dependency is not specified in arch/arm64/Makefile.

To address IO performance commit f9e5b33934ce ("mmc: host: Improve I/O read/write performance for GL9763E") limited LPM negotiation to runtime suspend state. The problem is that it only flips the switch in the runtime PM resume/suspend logic. Disable LPM negotiation in gl9763e_add_host. This helps in two ways: 1. It was found that the LPM switch stays in the same position after warm reboot. Having it set in init helps with consistency. 2. Disabling LPM during the first runtime resume leaves us susceptible to the performance issue in the time window between boot and the first runtime suspend.

2023-11-23tls: fix NULL deref on tls_sw_splice_eof() with empty recordJann Horn
syzkaller discovered that if tls_sw_splice_eof() is executed as part of sendfile() when the plaintext/ciphertext sk_msg are empty, the send path gets confused because the empty ciphertext buffer does not have enough space for the encryption overhead. This causes tls_push_record() to go on the `split = true` path (which is only supposed to be used when interacting with an attached BPF program), and then get further confused and hit the tls_merge_open_record() path, which then assumes that there must be at least one populated buffer element, leading to a NULL deref. It is possible to have empty plaintext/ciphertext buffers if we previously bailed from tls_sw_sendmsg_locked() via the tls_trim_both_msgs() path. tls_sw_push_pending_record() already handles this case correctly; let's do the same check in tls_sw_splice_eof().

2023-11-23Merge branch 'ice-restore-timestamp-config-after-reset'Paolo Abeni
Tony Nguyen says: ==================== ice: restore timestamp config after reset Jake Keller says: We recently discovered during internal validation that the ice driver has not been properly restoring Tx timestamp configuration after a device reset, which resulted in application failures after a device reset. After some digging, it turned out this problem is two-fold. Since the introduction of the PTP support the driver has been clobbering the storage of the current timestamp configuration during reset. Thus after a reset, the driver will no longer perform Tx or Rx timestamps, and will report timestamp configuration as disabled if SIOCGHWTSTAMP ioctl is issued. In addition, the recently merged auxiliary bus support code missed that PFINT_TSYN_MSK must be reprogrammed on the clock owner for E822 devices. Failure to restore this register configuration results in the driver no longer responding to interrupts from other ports. Depending on the traffic pattern, this can either result in increased latency responding to timestamps on the non-owner ports, or it can result in the driver never reporting any timestamps. The configuration of PFINT_TSYN_MSK was only done during initialization. Due to this, the Tx timestamp issue persists even if userspace reconfigures timestamping. This series fixes both issues, as well as removes a redundant Tx ring field since we can rely on the skb flag as the primary detector for a Tx timestamp request. Note that I don't think this series will directly apply to older stable releases (even v6.6) as we recently refactored a lot of the PTP code to support auxiliary bus. Patch 2/3 only matters for the post-auxiliary bus implementation. The principle of patch 1/3 and 3/3 could apply as far back as the initial PTP support, but I don't think it will apply cleanly as-is. ==================== Link: https://lore.kernel.org/r/20231121211259.3348630-1-anthony.l.nguyen@intel.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>
2023-11-23ice: restore timestamp configuration after device resetJacob Keller
The driver calls ice_ptp_cfg_timestamp() during ice_ptp_prepare_for_reset() to disable timestamping while the device is resetting. This operation destroys the user requested configuration. While the driver does call ice_ptp_cfg_timestamp in ice_rebuild() to restore some hardware settings after a reset, it unconditionally passes true or false, resulting in failure to restore previous user space configuration. This results in a device reset forcibly disabling timestamp configuration regardless of current user settings. This was not detected previously due to a quirk of the LinuxPTP ptp4l application. If ptp4l detects a missing timestamp, it enters a fault state and performs recovery logic which includes executing SIOCSHWTSTAMP again, restoring the now accidentally cleared configuration. Not every application does this, and for these applications, timestamps will mysteriously stop after a PF reset, without being restored until an application restart. Fix this by replacing ice_ptp_cfg_timestamp() with two new functions: 1) ice_ptp_disable_timestamp_mode() which unconditionally disables the timestamping logic in ice_ptp_prepare_for_reset() and ice_ptp_release() 2) ice_ptp_restore_timestamp_mode() which calls ice_ptp_restore_tx_interrupt() to restore Tx timestamping configuration, calls ice_set_rx_tstamp() to restore Rx timestamping configuration, and issues an immediate TSYN_TX interrupt to ensure that timestamps which may have occurred during the device reset get processed. Modify the ice_ptp_set_timestamp_mode to directly save the user configuration and then call ice_ptp_restore_timestamp_mode. This way, reset no longer destroys the saved user configuration. This obsoletes the ice_set_tx_tstamp() function which can now be safely removed. With this change, all devices should now restore Tx and Rx timestamping functionality correctly after a PF reset without application intervention.

2023-11-23ice: unify logic for programming PFINT_TSYN_MSKJacob Keller
Commit d938a8cca88a ("ice: Auxbus devices & driver for E822 TS") modified how Tx timestamps are handled for E822 devices. On these devices, only the clock owner handles reading the Tx timestamp data from firmware. To do this, the PFINT_TSYN_MSK register is modified from the default value to one which enables reacting to a Tx timestamp on all PHY ports. The driver currently programs PFINT_TSYN_MSK in different places depending on whether the port is the clock owner or not. For the clock owner, the PFINT_TSYN_MSK value is programmed during ice_ptp_init_owner just before calling ice_ptp_tx_ena_intr to program the PHY ports. For the non-clock owner ports, the PFINT_TSYN_MSK is programmed during ice_ptp_init_port. If a large enough device reset occurs, the PFINT_TSYN_MSK register will be reset to the default value in which only the PHY associated directly with the PF will cause the Tx timestamp interrupt to trigger. The driver lacks logic to reprogram the PFINT_TSYN_MSK register after a device reset. For the E822 device, this results in the PF no longer responding to interrupts for other ports. This results in failure to deliver Tx timestamps to user space applications. Rename ice_ptp_configure_tx_tstamp to ice_ptp_cfg_tx_interrupt, and unify the logic for programming PFINT_TSYN_MSK and PFINT_OICR_ENA into one place. This function will program both registers according to the combination of user configuration and device requirements. This ensures that PFINT_TSYN_MSK is always restored when we configure the Tx timestamp interrupt.

2023-11-23ice: remove ptp_tx ring parameter flagJacob Keller
Before performing a Tx timestamp in ice_stamp(), the driver checks a ptp_tx ring variable to see if timestamping is enabled on that ring. This value is set for all rings whenever userspace configures Tx timestamping. Ostensibly this was done to avoid wasting cycles checking other fields when timestamping has not been enabled. However, for Tx timestamps we already get an individual per-SKB flag indicating whether userspace wants to request a timestamp on that packet. We do not gain much by also having a separate flag to check for whether timestamping was enabled. In fact, the driver currently fails to restore the field after a PF reset. Because of this, if a PF reset occurs, timestamps will be disabled. Since this flag doesn't add value in the hotpath, remove it and always provide a timestamp if the SKB flag has been set. A following change will fix the reset path to properly restore user timestamping configuration completely. This went unnoticed for some time because one of the most common applications using Tx timestamps, ptp4l, will reconfigure the socket as part of its fault recovery logic.

queue than its PF It is possible to add a ntuple rule which would like to direct packet to a VF whose number of queues are greater/less than its PF's queue numbers. For example a PF can have 2 Rx queues but a VF created on that PF can have 8 Rx queues. As of today, ntuple rule will reject rule because it is checking the requested queue number against PF's number of Rx queues. As a part of this fix if the action of a ntuple rule is to move a packet to a VF's queue then the check is removed. Also, a debug information is printed to aware user that it is user's responsibility to cross check if the requested queue number on that VF is a valid one.
