2022-04-08vppinfra: clib_interrupt_get_next reading unallocated memoryPaul Atkins2-1/+82
The clib interrupt structure has a couple of fields at the start of the cacheline, and then in the next cacheline it has a bitmap, which is then followed by an atomic bitmap. The size of the bitmaps is based on the number of interrupts, and when the memory is allocated the number of interrupts needed is used to size the overall block of memory. The interrupts typically map to pool entries, so if we want to store 512 entries then we store them in indices 0..511. This would then take 8 6 4bit words, so each bitmap would be this size when the struct is allocated. It is possible to walk over the end of the allocated data with certain sizes, one of which is 512. The reason this happens with 512 is that the check to see when to exit the loop is returning when offset is greater than the value needed to fit all the values. In this case 512 >> 6 = 8. If there had only been 511 entries then the size would have been 511 >> 6 = 7, and so it would have fitted in the space. Therefore modify the check to also check that we are not looking into the memory beyond what we have allocated in the case where the number of interrupt is one of the boundary values like 512. Also add a similar check first time round the loop as it is possible we could have ate same problem there too. Add a new test file to verify the new code works. The old version of the code made this test fail when run with the address sanitizer. Without the sanitiser it tended to pass because the following memory was typically set to 0 even though it was uninitialised.

2022-03-30vppinfra: vector allocator reworkDamjan Marion20-932/+866
- support of in-place growth of vectors (if there is available space next to existing alloc) - drops the need for alloc_aligned_at_offset from memory allocator, which allows easier swap to different memory allocator and reduces malloc overhead - rework of pool and vec macros to inline functions to improve debuggability - fix alignment - in many cases macros were not using native alignment of the particular datatype. Explicitly setting alignment with XXX_aligned() versions of the macro is not needed anymore in > 99% of cases - fix ASAN usage - avoid use of vector of voids, this was root cause of several bugs found in vec_* and pool_* function where sizeof() was used on voids instead of real vector data type - introduce minimal alignment which is currently 8 bytes, vectors will be always aligned at least to that value (underlay allocator actually always provide 16-byte aligned allocs) Type: improvement Change-Id: I20f4b081bb13bbf7bc0ace85cc4e301787f12fdf Signed-off-by: Damjan Marion <damarion@cisco.com>

2022-03-09vat: fix vat_suspend crashDamjan Marion1-0/+6
Deadly combination is clib_{set,long}jmp + lazy linking + tail call compiler optimization. On the first call to clib_setjmp, dynamic linker executes loader code which then calls clib_setjmp, so stored stack position contains dynamic loader data. Tail call optimization simply jumps back to the calling code when clib_longjump is called and that results in wrong return address used from the stack.
