Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions).

Direct calls to ops->connect() can overwrite the address parameter when used in conjunction with BPF SOCK_ADDR hooks. Recent changes to kernel_connect() ensure that callers are insulated from such side effects. This patch wraps the direct call to ops->connect() with kernel_connect() to prevent unexpected changes to the address passed to ceph_tcp_connect().

Before returning, function ceph_fname_to_usr() does a final IS_ERR() check in 'dir': if ((dir != fname->dir) && !IS_ERR(dir)) {...} This check is unnecessary because, if the 'dir' variable has changed to something other than 'fname->dir' (it's initial value), that error check has been performed already and, if there was indeed an error, it would have been returned immediately.

When truncating the inode the MDS will acquire the xlock for the ifile Locker, which will revoke the 'Frwsxl' caps from the clients. But when the client just releases and flushes the 'Fw' caps to MDS, for exmaple, and once the MDS receives the caps flushing msg it just thought the revocation has finished. Then the MDS will continue truncating the inode and then issued the truncate notification to all the clients. While just before the clients receives the cap flushing ack they receive the truncation notification, the clients will detecte that the 'issued | dirty' is still holding the 'Fw' caps.

Currently driver maintain one list for both pending user interrupts which seeks to wait till CQ reaches it's target value and also the ones that seeks to get timestamp records when the CQ reaches it's target value. This causes delay in handling the waiters which gets higher priority than the timestamp records. In order to solve this, let's split the list into two, one for each case and each one is protected by it's own spinlock.

2023-10-09accel/habanalabs: optimize timestamp registration handlerfarah kassabri
Currently we use dynamic allocation inside the irq handler in order to allocate free node to be used for the free jobs. This operation is expensive, especially when we deal with large burst of events records that get released at the same time. The alternative is to have pre allocated pool of free nodes and just fetch nodes from this pool at irq handling time instead of allocating them. In case the pool becomes full, then the driver will fallback to dynamic allocations. As part of the optimization also update the unregister flow upon re-using a timestamp record, by making the operation much simpler and quicker. We already have the record in the registration flow and now we just seek to re-use with different interrupt. Therefore, no need to look for buffer according to the user handle.

Imagine the driver set the record in_use to 0 and only then fill the free_node information. This might lead to unpleasant scenario where the new registration thread detects the record as free to use, and change the cq buff address.
