5b2b117 Merge tag 'trace-v6.7-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt:: "Eventfs fixes: - With the usage of simple_recursive_remove() recommended by Al Viro, the code should not be calling "d_invalidate()" itself. Doing so is causing crashes. The code was calling d_invalidate() on the race of trying to look up a file while the parent was being deleted. This was detected, and the added dentry was having d_invalidate() called on it, but the deletion of the directory was also calling d_invalidate() on that same dentry. - A fix to not free the eventfs_inode (ei) until the last dput() was called on its ei->dentry made the ei->dentry exist even after it was marked for free by setting the ei->is_freed. But code elsewhere still was checking if ei->dentry was NULL if ei->is_freed is set and would trigger WARN_ON if that was the case. That's no longer true and there should not be any warnings when it is true. - Use GFP_NOFS for allocations done under eventfs_mutex. The eventfs_mutex can be taken on file system reclaim, make sure that allocations done under that mutex do not trigger file system reclaim. - Clean up code by moving the taking of inode_lock out of the helper functions and into where they are needed, and not use the parameter to know to take it or not. It must always be held but some callers of the helper function have it taken when they were called. - Warn if the inode_lock is not held in the helper functions. - Warn if eventfs_start_creating() is called without a parent. As eventfs is underneath tracefs, all files created will have a parent (the top one will have a tracefs parent). Tracing update: - Add Mathieu Desnoyers as an official reviewer of the tracing subsystem" * tag 'trace-v6.7-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: MAINTAINERS: TRACING: Add Mathieu Desnoyers as Reviewer eventfs: Make sure that parent->d_inode is locked in creating files/dirs eventfs: Do not allow NULL parent to eventfs_start_creating() eventfs: Move taking of inode_lock into dcache_dir_open_wrapper() eventfs: Use GFP_NOFS for allocation when eventfs_mutex is held eventfs: Do not invalidate dentry in create_file/dir_dentry() eventfs: Remove expectation that ei->is_freed means ei->dentry == NULL 27 November 2023, 03:48:20 UTC
d2da77f Merge tag 'parisc-for-6.7-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux Pull parisc architecture fixes from Helge Deller: "This patchset fixes and enforces correct section alignments for the ex_table, altinstructions, parisc_unwind, jump_table and bug_table which are created by inline assembly. Due to not being correctly aligned at link & load time they can trigger unnecessarily the kernel unaligned exception handler at runtime. While at it, I switched the bug table to use relative addresses which reduces the size of the table by half on 64-bit. We still had the ENOSYM and EREMOTERELEASE errno symbols as left-overs from HP-UX, which now trigger build-issues with glibc. We can simply remove them. Most of the patches are tagged for stable kernel series. Summary: - Drop HP-UX ENOSYM and EREMOTERELEASE return codes to avoid glibc build issues - Fix section alignments for ex_table, altinstructions, parisc unwind table, jump_table and bug_table - Reduce size of bug_table on 64-bit kernel by using relative pointers" * tag 'parisc-for-6.7-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Reduce size of the bug_table on 64-bit kernel by half parisc: Drop the HP-UX ENOSYM and EREMOTERELEASE error codes parisc: Use natural CPU alignment for bug_table parisc: Ensure 32-bit alignment on parisc unwind section parisc: Mark lock_aligned variables 16-byte aligned on SMP parisc: Mark jump_table naturally aligned parisc: Mark altinstructions read-only and 32-bit aligned parisc: Mark ex_table entries 32-bit aligned in uaccess.h parisc: Mark ex_table entries 32-bit aligned in assembly.h 26 November 2023, 17:59:39 UTC

fa2b906 Merge tag 'vfs-6.7-rc3.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull vfs fixes from Christian Brauner: - Avoid calling back into LSMs from vfs_getattr_nosec() calls. IMA used to query inode properties accessing raw inode fields without dedicated helpers. That was finally fixed a few releases ago by forcing IMA to use vfs_getattr_nosec() helpers. The goal of the vfs_getattr_nosec() helper is to query for attributes without calling into the LSM layer which would be quite problematic because incredibly IMA is called from __fput()... __fput() -> ima_file_free() What it does is to call back into the filesystem to update the file's IMA xattr. Querying the inode without using vfs_getattr_nosec() meant that IMA didn't handle stacking filesystems such as overlayfs correctly. So the switch to vfs_getattr_nosec() is quite correct. But the switch to vfs_getattr_nosec() revealed another bug when used on stacking filesystems: __fput() -> ima_file_free() -> vfs_getattr_nosec() -> i_op->getattr::ovl_getattr() -> vfs_getattr() -> i_op->getattr::$WHATEVER_UNDERLYING_FS_getattr() -> security_inode_getattr() # calls back into LSMs Now, if that __fput() happens from task_work_run() of an exiting task current->fs and various other pointer could already be NULL. So anything in the LSM layer relying on that not being NULL would be quite surprised. Fix that by passing the information that this is a security request through to the stacking filesystem by adding a new internal ATT_GETATTR_NOSEC flag. Now the callchain becomes: __fput() -> ima_file_free() -> vfs_getattr_nosec() -> i_op->getattr::ovl_getattr() -> if (AT_GETATTR_NOSEC) vfs_getattr_nosec() else vfs_getattr() -> i_op->getattr::$WHATEVER_UNDERLYING_FS_getattr() - Fix a bug introduced with the iov_iter rework from last cycle. This broke /proc/kcore by copying too much and without the correct offset. - Add a missing NULL check when allocating the root inode in autofs_fill_super(). - Fix stable writes for multi-device filesystems (xfs, btrfs etc) and the block device pseudo filesystem. Stable writes used to be a superblock flag only, making it a per filesystem property. Add an additional AS_STABLE_WRITES mapping flag to allow for fine-grained control. - Ensure that offset_iterate_dir() returns 0 after reaching the end of a directory so it adheres to getdents() convention. * tag 'vfs-6.7-rc3.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: libfs: getdents() should return 0 after reaching EOD xfs: respect the stable writes flag on the RT device xfs: clean up FS_XFLAG_REALTIME handling in xfs_ioctl_setattr_xflags block: update the stable_writes flag in bdev_add filemap: add a per-mapping stable writes flag autofs: add: new_inode check in autofs_fill_super() iov_iter: fix copy_page_to_iter_nofault() fs: Pass AT_GETATTR_NOSEC flag to getattr interface function 24 November 2023, 17:45:40 UTC

b590eb4 afs: Fix file locking on R/O volumes to operate in local mode AFS doesn't really do locking on R/O volumes as fileservers don't maintain state with each other and thus a lock on a R/O volume file on one fileserver will not be be visible to someone looking at the same file on another fileserver. Further, the server may return an error if you try it. Fix this by doing what other AFS clients do and handle filelocking on R/O volume files entirely within the client and don't touch the server.

That would mean @size == 0, at which point size_to_bucket() returns -1 and the above happens. alloc_chain_hlocks() has 'size - req', for the first with the precondition 'size >= rq', which allows the 0. This code is trying to split a block, del_chain_block() takes what we need, and add_chain_block() puts back the remainder, except in the above case the remainder is 0 sized and things go sideways.

c0a8574 arm64: add dependency between vmlinuz.efi and Image 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.

53f2cb4 tls: fix NULL deref on tls_sw_splice_eof() with empty record 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().

e50a806 Merge branch 'ice-restore-timestamp-config-after-reset' 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> 23 November 2023, 14:27:35 UTC
7758017 ice: restore timestamp configuration after device reset 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.

7d606a1 ice: unify logic for programming PFINT_TSYN_MSK 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.

0ffb08b ice: remove ptp_tx ring parameter flag 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.

4aa1d8f octeontx2-pf: Fix ntuple rule creation to direct packet to VF with higher Rx 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.

0e6c4fe nvme: tcp: fix compile-time checks for TLS mode When CONFIG_NVME_KEYRING is enabled as a loadable module, but the TCP host code is built-in, it fails to link: arm-linux-gnueabi-ld: drivers/nvme/host/tcp.o: in function `nvme_tcp_setup_ctrl': tcp.c:(.text+0x1940): undefined reference to `nvme_tls_psk_default' The problem is that the compile-time conditionals are inconsistent here, using a mix of #ifdef CONFIG_NVME_TCP_TLS, IS_ENABLED(CONFIG_NVME_TCP_TLS) and IS_ENABLED(CONFIG_NVME_KEYRING) checks, with CONFIG_NVME_KEYRING controlling whether the implementation is actually built. Change it to use IS_ENABLED(CONFIG_NVME_KEYRING) checks consistently, which should help readability and make it less error-prone. Combining it with the check for the ctrl->opts->tls flag lets the compiler drop all the TLS code in configurations without this feature, which also helps runtime behavior in addition to avoiding the link failure. To make it possible for the compiler to build the dead code, both the tls_handshake_timeout variable and the TLS specific members of nvme_tcp_queue need to be moved out of the #ifdef block as well, but at least the former of these gets optimized out again.

125b0bb asm-generic: qspinlock: fix queued_spin_value_unlocked() implementation We really don't want to do atomic_read() or anything like that, since we already have the value, not the lock. The whole point of this is that we've loaded the lock from memory, and we want to check whether the value we loaded was a locked one or not. The main use of this is the lockref code, which loads both the lock and the reference count in one atomic operation, and then works on that combined value. With the atomic_read(), the compiler would pointlessly spill the value to the stack, in order to then be able to read it back "atomically".

3af755a nvme: move nvme_stop_keep_alive() back to original position Stopping keep-alive not only stops the keep-alive workqueue, but also needs to be synchronized with I/O termination as we must not send a keep-alive command after all I/O had been terminated. So to avoid any regressions move the call to stop_keep_alive() back to its original position and ensure that keep-alive is correctly stopped failing to setup the admin queue.

aab1f80 scripts/checkstack.pl: match all stack sizes for s390 For some unknown reason the regular expression for checkstack only matches three digit numbers starting with the number "3", or any higher number. Which means that it skips any stack sizes smaller than 304 bytes. This makes the checkstack script a bit less useful than it could be. Change the script to match any number. To be filtered out stack sizes can be configured with the min_stack variable, which omits any stack frame sizes smaller than 100 bytes by default.

6a26310 Revert "net: r8169: Disable multicast filter for RTL8168H and RTL8107E" This reverts commit efa5f1311c4998e9e6317c52bc5ee93b3a0f36df. I couldn't reproduce the reported issue. What I did, based on a pcap packet log provided by the reporter: - Used same chip version (RTL8168h) - Set MAC address to the one used on the reporters system - Replayed the EAPOL unicast packet that, according to the reporter, was filtered out by the mc filter. The packet was properly received. Therefore the root cause of the reported issue seems to be somewhere else. Disabling mc filtering completely for the most common chip version is a quite big hammer. Therefore revert the change and wait for further analysis results from the reporter. Cc: stable@vger.kernel.org Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S.

e6d71b4 net/smc: avoid data corruption caused by decline We found a data corruption issue during testing of SMC-R on Redis applications. The benchmark has a low probability of reporting a strange error as shown below. "Error: Protocol error, got "\xe2" as reply type byte" Finally, we found that the retrieved error data was as follows: 0xE2 0xD4 0xC3 0xD9 0x04 0x00 0x2C 0x20 0xA6 0x56 0x00 0x16 0x3E 0x0C 0xCB 0x04 0x02 0x01 0x00 0x00 0x20 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0xE2 It is quite obvious that this is a SMC DECLINE message, which means that the applications received SMC protocol message. We found that this was caused by the following situations: client server ¦ clc proposal -------------> ¦ clc accept <------------- ¦ clc confirm -------------> wait llc confirm send llc confirm ¦failed llc confirm ¦ x------ (after 2s)timeout wait llc confirm rsp wait decline (after 1s) timeout (after 2s) timeout ¦ decline --------------> ¦ decline <-------------- As a result, a decline message was sent in the implementation, and this message was read from TCP by the already-fallback connection. This patch double the client timeout as 2x of the server value, With this simple change, the Decline messages should never cross or collide (during Confirm link timeout). This issue requires an immediate solution, since the protocol updates involve a more long-term solution. Fixes: 0fb0b02bd6fd ("net/smc: adapt SMC client code to use the LLC flow") Signed-off-by: D.

The touchpad do report the input mode at touchpad(3), while itself working under mouse mode. As a workaround, it is possible to call MT_QUIRE_FORCE_GET_FEATURE to force set feature in mt_set_input_mode for such device. The touchpad reports as BLTP7853, which cannot retrive any useful manufacture information on the internel by this string at present. As the serial number of the laptop is GLO-G52, while DMI info reports the laptop serial number as GLO-GXXX, this workaround should applied to all models which has the GLO-GXXX.
