2023-10-30ipsec: huge anti-replay window supportMaxime Peim1-7/+12
Type: improvement Since RFC4303 does not specify the anti-replay window size, VPP should support multiple window size. It is done through a clib_bitmap. Signed-off-by: Maxime Peim <mpeim@cisco.com> Change-Id: I3dfe30efd20018e345418bef298ec7cec19b1cfc
2023-08-09session: async rx event notificationsFlorin Coras1-1/+69
Move from synchronous flushing of io and ctrl events from transports to applications to an async model via a new session_input input node that runs in interrupt mode. Events are coalesced per application worker. On the one hand, this helps by minimizing message queue locking churn. And on the other, it opens the possibility for further optimizations of event message generation, obviates need for rx rescheduling rpcs and is a first step towards a fully async data/io rx path.

2023-03-06crypto: remove VNET_CRYPTO_OP_FLAG_INIT_IV flagBenoît Ganne1-1/+0
IV requirements vary wildly with the selected mode of operation. For example, for AES-CBC the IV must be unpredictable whereas for AES counter mode (CTR or GCM), it can be predictable but reusing an IV with the same key material is catastrophic. Because of that, it is hard to generate IV in a generic way, and it is better left to the crypto user (eg. IPsec).

2023-03-06vppinfra: fix clib_bitmap_will_expand() result inversionVladislav Grishenko1-0/+50
Pool's pool_put_will_expand() calls clib_bitmap_will_expand(), so every put except ones that leads to free_bitmap reallocation will get false positive results and vice versa. Unfortunatelly there's no related test and existing bitmap tests are failing silently with false positive result as well. Fortunatelly neither clib_bitmap_will_expand() nor pool_put_will_expand() are being used by current vpp codebase.

In clib_bitmap_set_region and clib_bitmap_set_multiple the index of the last bit to set was off by 1. If this index was pointing to the last bit of the bitmap, another uword would have been allocated, even though it was unnecessary. Moreover, in clib_bitmap_set_region, bits in the last word were not properly set. Indeed, the n_bits_left value is wrong since n_bits is not decreased by the number of already set bits.

2022-03-30vppinfra: vector allocator reworkDamjan Marion1-25/+2
- 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>

2022-02-16fib: Use the same adjacency that BFD is usingNeale Ranns1-2/+4
Type: improvement When the adj subsystem is notified of a BFD session, it attempts to find the appropriate adjacency from the session's key. This could lead to a mismatch between the adj used by BFD and that of FIB. The BFD session stores the adj it is using, so FIB uses that instead. Since adj is now using the same adj as BFD, it does not need to maintain its own locks. In BFD it is necessary to initialise the adj index used in INVALID and ensure it is not unlock before listeners are notified of the session delete.

2021-11-05unittest: gcc-11 errors for clib_strcpy, clib_strstr, clib_strcat, and ↵Steven Luong1-340/+30
clib_strncat There are 3 versions of the string functions. For example, for strcpy, they are 1. strcpy(dst, src) -- the legacy unsafe version 2. strcpy_s(dst, dmax, src) -- C11 safeC version which has an addition argument named dmax. 3. clib_strcpy(dst,src) -- clib version to enable legacy code that uses strcpy to make use of strcpy_s without adding the additional argument, dmax, which is required by the C11 safeC version. The implementation for the clib version is to artificially provide dmax to strcpy_s. In this case, it uses 4096 which assumes that if the legacy code works without blowing up, it is likely to work with the clib version without problem. gcc-11 is getting smarter by checking if dmax is within the object's boundary. When the object is declared as static array, it will flag a warning/error if dmax is out of bound for the object since the real size of dst can be determined at compile time. There is no way to find the real size of dst if the object is dynamically allocated at compile time. For this reason, we simply can't provide support for the clib version of the function anymore. If any code is using the clib version, the choice is to migrate to the safeC version.

2021-10-21fib: respect mfib entry flags on create with pathsPaul Atkins2-96/+58
When an mfib entry was created with both paths and entry_flags then the entry flags were being ignored. If there are no paths then the flags were passed into mfib_table_entry_update, but in the case where the entry didn't exist and there were paths and flags, the entry was created within mfib_table_entry_paths_update() which used a default of MFIB_ENTRY_FLAG_NONE.

2021-10-11ip: fix fib and mfib locksNathan Skrzypczak3-9/+5
This patches fixes an issue that could cause fib locks to underflow: if an API user deletes a fib and quickly recreates it, the fib may not have been actually deleted. As a result, the lock would not be incremented on the create call leading to the fib potentially disappearing afterwards - or to the lock to underflow when the fib is deleted again. In order to keep the existing API semantics, we use the locks with API and CLI source as flags. This means we need to use a different counter for the interface-related locks. This also prevents an issue where an interface being bound to a vrf via API and released via CLI could mess up the lock counter. Finally, this will help with cleaning up the interface-related locks on interface deletion in a later patch.

2021-10-04vppinfra: fix potential memory access error in _pool_init_fixedJieqiang Wang1-15/+23
_pool_init_fixed uses mmap to initialize a fixed-size and preallocated pool, whose size is the sum of vector_size and free_index_size with alignment to the CLIB_CACHE_LINE_BYTES and page size. In this way vector_size equals to pool_header_t + vec_header_t + elt_size * max_elts so moving to the end of the pool space should be pool_header_t pointer + vector_size, instead of vec_header_t pointer + vector_size.
