2023-08-24PCI: brcmstb: Remove stale commentJim Quinlan
A comment says that Multi-MSI is not supported by the driver. A past commit [1] added this feature, so the comment is incorrect and is removed.

2023-08-24PCI: brcmstb: Assert PERST# on BCM2711Jim Quinlan
The current PCIe driver assumes PERST# is asserted when probe() is invoked. Some older versions of the 2711/RPi bootloader left PERST# unasserted, as the Raspian OS does assert PERST# on probe(). For this reason, we assert PERST# for BCM2711 SOCs (i.e. RPi).

Currently, in function bpf_obj_free_fields(), for local kptr, a warning will be issued if the struct does not contain any special fields. But actually the kernel seems totally okay with a local kptr without any special fields. Permitting no special fields also aligns with future percpu kptr which also allows no special fields.

2023-08-24powerpc/pseries: Rework lppaca_shared_proc() to avoid DEBUG_PREEMPTRussell Currey
lppaca_shared_proc() takes a pointer to the lppaca which is typically accessed through get_lppaca(). With DEBUG_PREEMPT enabled, this leads to checking if preemption is enabled, for example: BUG: using smp_processor_id() in preemptible [00000000] code: grep/10693 caller is lparcfg_data+0x408/0x19a0 CPU: 4 PID: 10693 Comm: grep Not tainted 6.5.0-rc3 #2 Call Trace: dump_stack_lvl+0x154/0x200 (unreliable) check_preemption_disabled+0x214/0x220 lparcfg_data+0x408/0x19a0 ... This isn't actually a problem however, as it does not matter which lppaca is accessed, the shared proc state will be the same. vcpudispatch_stats_procfs_init() already works around this by disabling preemption, but the lparcfg code does not, erroring any time /proc/powerpc/lparcfg is accessed with DEBUG_PREEMPT enabled. Instead of disabling preemption on the caller side, rework lppaca_shared_proc() to not take a pointer and instead directly access the lppaca, bypassing any potential preemption checks.

The only callers of zalloc_maybe_bootmem() are PCI setup routines. These used to be called early during boot before slab setup, and also during runtime due to hotplug. But commit 5537fcb319d0 ("powerpc/pci: Add ppc_md.discover_phbs()") moved the boot-time calls later, after slab setup, meaning there's no longer any need for zalloc_maybe_bootmem(), kzalloc() can be used in all cases.

git://git.kernel.org/pub/scm/linux/kernel/git/djakov/icc into char-misc-next Georgi writes: interconnect changes for 6.6 This pull request contains the interconnect changes for the 6.6-rc1 merge window which is a mix of core and driver changes with the following highlights: Core changes: - New generic test client driver that allows issuing bandwidth requests between endpoints via debugfs. - Annotate all structs with flexible array members with the __counted_by attribute. - Introduce new icc_bw_lock for cases where we need to serialize bandwidth aggregation and update to decouple that from paths that require memory allocation. Driver changes: - Move the Qualcomm SMD RPM bus-clocks from CCF to interconnect framework where they actually belong. This brings power management improvements and reduces the overhead and layering. These changes are in immutable branch that is being pulled also into the qcom tree. - Fixes for QUP nodes on SM8250. - Enable sync_state and keepalive for QCM2290. - Enable sync_state for SM8450. - Improve enable_mask-based BCMs handling and fix some bugs. - Add compatible string for the OSM-L3 on SDM670. - Add compatible strings for SC7180, SM8250 and SM6350 bandwidth monitors. - Expand and retire the DEFINE_QNODE and DEFINE_QBCM macros, which have become ugly beasts with many different arguments.

This will be buggy when the waiter require the req->r_callback()s to release some resources before continuing.

2023-08-24ceph: add support for encrypted snapshot namesLuís Henriques
Since filenames in encrypted directories are encrypted and shown as a base64-encoded string when the directory is locked, make snapshot names show a similar behaviour. When creating a snapshot, .snap directories for every subdirectory will show the snapshot name in the "long format": # mkdir .snap/my-snap # ls my-dir/.snap/ _my-snap_1099511627782 Encrypted snapshots will need to be able to handle these by encrypting/decrypting only the snapshot part of the string ('my-snap'). Also, since the MDS prevents snapshot names to be bigger than 240 characters it is necessary to adapt CEPH_NOHASH_NAME_MAX to accommodate this extra limitation.

When doing a synchronous write on an encrypted inode, we have no guarantee that the caller is writing crypto block-aligned data. When that happens, we must do a read/modify/write cycle. First, expand the range to cover complete blocks. If we had to change the original pos or length, issue a read to fill the first and/or last pages, and fetch the version of the object from the result. We then copy data into the pages as usual, encrypt the result and issue a write prefixed by an assertion that the version hasn't changed. If it has changed then we restart the whole thing again. If there is no object at that position in the file (-ENOENT), we prefix the write on an exclusive create of the object instead.

2023-08-24ceph: mark directory as non-complete after loading keyLuís Henriques
When setting a directory's crypt context, ceph_dir_clear_complete() needs to be called otherwise if it was complete before, any existing (old) dentry will still be valid. This patch adds a wrapper around __fscrypt_prepare_readdir() which will ensure a directory is marked as non-complete if key status changes.
