2022-08-18vppinfra: correct clib_bitmap_set() return commentJon Loeliger1-1/+1
Fix a copy-n-paste issue that left clib_bitmap_set()'s return type documentation incorrect. Chnage it to indicate that the function returns a new pointer for the bitmap that could be different due to a possible reallocation.

2022-04-04vppinfra: make _vec_len() read-onlyDamjan Marion1-24/+27
Use of _vec_len() to set vector length breaks address sanitizer. Users should use vec_set_len(), vec_inc_len(), vec_dec_len () instead. Type: improvement Change-Id: I441ae948771eb21c23a61f3ff9163bdad74a2cb8 Signed-off-by: Damjan Marion <damarion@cisco.com>

2022-01-01vppinfra: fix bitmap can't get correct next clear indexjiangxiaoming1-2/+1
when bitmap vec len is 1 and all the bits has been occupied, clib_bitmap_next_clear(ai, 63) will return result:65 which should be 64. It will lead to missing iteration for pool_foreach.

2018-07-04Fix clib_bitmap_next_clear() function when no clear bits leftJohn Lo1-0/+3
If the bitmap has no bit clear after the input bit position i, the function will return i even if its bit is set. Fix is to return the next bit just beyond the free bitmap. This can cause IP neighbor scan crash in ip_neighbor_scan() with a debug image. With production image, ip_neighbor_scan() may still function, AFAICT, with extra neighbor delete attempts for entries already deleted, until these entries are reused for new neighbors.
