However * after hash map was fully converted to use bpf_mem_alloc, there will be * non-synchronous memory allocation for non-preallocated hash map, so it is * safe to always use raw spinlock for bucket lock. Before the introduction of bpf_mem_alloc, * it is only safe to use raw spinlock for preallocated hash map on a RT kernel, * because there is no memory allocation within the lock held sections. * * In theory the BPF locks could be converted to regular spinlocks as well, * but the bucket locks and percpu_freelist locks can be taken from * arbitrary contexts (perf, kprobes, tracepoints) which are required to be * atomic contexts even on RT.

* * As regular device interrupt handlers and soft interrupts are forced into * thread context, the existing code which does * spin_lock*() alloc(GFP_ATOMIC) spin_unlock*() * just works. None of * these contexts should ever do memory allocations. The only * true atomic contexts on an RT kernel are the low level hardware * handling, scheduling, low level interrupt handling, NMIs etc. To ensure the deterministic behaviour these locks are regular * spinlocks, which are converted to 'sleepable' spinlocks on RT. This is required because even with GFP_ATOMIC the memory * allocator calls into code paths which acquire locks with long held lock * sections. PREEMPT_RT forbids certain * operations like memory allocations (even with GFP_ATOMIC) from atomic * contexts.

* * This has subtle implications on PREEMPT_RT. Do not restart the server Install the new license right away. sys_bpf() uses the same mechanism * by pinning the task to the current CPU and incrementing the recursion * protection across the map operation. BPF recursion is prevented by incrementing the per CPU * variable bpf_prog_active, which prevents BPF programs attached to perf * events, kprobes and tracing to be invoked before the prior invocation * from one of these contexts completed. Deadlocks can be caused by recursion and by an invocation in * the lock held section when functions which acquire this lock are invoked * from sys_bpf(). As there are almost no limits where perf, kprobes and tracing * can be invoked from the lock operations need to be protected against * deadlocks. map_delete_batch = \ generic_map_delete_batch /* * The bucket lock has two protection scopes: * * 1) Serializing concurrent operations from BPF programs on different * CPUs * * 2) Serializing concurrent operations from BPF programs and sys_bpf() * * BPF programs can execute in any context including perf, kprobes and * tracing. map_update_batch = \ generic_map_update_batch, \. map_lookup_and_delete_batch = \ _name#_map_lookup_and_delete_batch, \. map_lookup_batch = \ _name#_map_lookup_batch, \. 4.// SPDX-License-Identifier: GPL-2.0-only /* Copyright (c) 2011-2014 PLUMgrid, * Copyright (c) 2016 Facebook */ #include #include #include #include #include #include #include #include #include #include " percpu_freelist.h" #include " bpf_lru_list.h" #include " map_in_map.h" #include #define HTAB_CREATE_FLAG_MASK \ ( BPF_F_NO_PREALLOC | BPF_F_NO_COMMON_LRU | BPF_F_NUMA_NODE | \ BPF_F_ACCESS_MASK | BPF_F_ZERO_SEED) #define BATCH_OPS( _name) \. Sorry not guna upload the whole file any more just the file 2 make it, All that is needed is a drag & drop of the above exe, and its done. You can also paste in hash text so you don't go cross-eyed trying to compare MD5 hashes. You can customize which hashes are calculated and displayed. This File Hashes window displays all the hashes for the file.

On Mac select More -> File Hashes this will start Hashtab providing more or less the same view that you see on Windows.
On Windows, select properties and you will see a new "File Hashes" tab. Once you have installed HashTab, just right click on any file. HashTab provides an easy way to verify file integrity and authenticity. Hashtab is supported as a Windows shell extension and a Mac Finder plugin. HashTab supports many hash algorithms such as MD5, SHA1, SHA2, RipeMD, HAVAL and Whirlpool. HashTab provides OS extensions to calculate file hashes.
