2023-03-23ipsec: make pre-shared keys harder to misuseBenoît Ganne2-0/+86
Using pre-shared keys is usually a bad idea, one should use eg. IKEv2 instead, but one does not always have the choice. For AES-CBC, the IV must be unpredictable (see NIST SP800-38a Appendix C) whereas for AES-CTR or AES-GCM, the IV should never be reused with the same key material (see NIST SP800-38a Appendix B and NIST SP800-38d section 8). If one uses pre-shared keys and VPP is restarted, the IV counter restarts at 0 and the same IVs are generated with the same pre-shared keys materials. To fix those issues we follow the recommendation from NIST SP800-38a and NIST SP800-38d: - we use a PRNG (not cryptographically secured) to generate IVs to avoid generating the same IV sequence between VPP restarts. The PRNG is chosen so that there is a low chance of generating the same sequence - for AES-CBC, the generated IV is encrypted as part of the message. This makes the (predictable) PRNG-generated IV unpredictable as it is encrypted with the secret key - for AES-CTR and GCM, we use the IV as-is as predictable IVs are fine Most of the changes in this patch are caused by the need to shoehorn an additional state of 2 u64 for the PRNG in the 1st cacheline of the SA object.

2023-03-19vppinfra: fix pool free bitmap allocationVladislav Grishenko3-1/+58
Using clib_bitmap_vec_validate makes free bitmap vector to be x64 times bigger (assuming x86_64) than necessary when non-zero and possible oom due (u32)(0 - 1) math with zero alloc. Fix it with clib_bitmap_validate which takes bit size, not index and ensure at least one bit is allocated.

2023-03-18vppinfra: fix corner-cases in bihash lookupDave Barach15-35/+196
In a case where one pounds on a single kvp in a KVP_AT_BUCKET_LEVEL table, the code would sporadically return a transitional value (junk) from a half-deleted kvp. At most, 64-bits worth of the kvp will be written atomically, so using memset(...) to smear 0xFF's across a kvp to free it left a lot to be desired. Performance impact: very mild positive, thanks to FC for doing a multi-thread host stack perf/scale test. Added an ASSERT to catch attempts to add a (key,value) pair which contains the magic "free kvp" value.

2023-03-06vppinfra: fix clib_bitmap_will_expand() result inversionVladislav Grishenko1-1/+1
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.

2022-11-14crypto-ipsecmb: fix plugin crash in VirtualBoxMaros Ondrejicka1-0/+1
Plugin checks just for AVX2 instruction set, while the v1.3 of IPsec Multi-Buffer library checks for both AVX2 and BMI2 sets during init. VirtualBox VM doesn't provide BMI2 by default to guest operating system. Result is that VPP plugin decides to use AVX2 initialization and library then doesn't do it. Since flush_job remains empty, the self-check fails and with that the whole VPP crashes on start-up.
