2019-07-31vppinfra: refactor test_and_set spinlocks to use clib_spinlock_tjaszha031-9/+5
Spinlock performance improved when implemented with compare_and_exchange instead of test_and_set. All instances of test_and_set locks were refactored to use clib_spinlock_t when possible. Some locks e.g. ssvm synchronize between processes rather than threads, so they cannot directly use clib_spinlock_t.

2019-07-30vppinfra: refactor use of CLIB_MEMORY_BARRIER ()jaszha031-2/+1
All instances of test_and_set locks used the following sequence to release the locks: CLIB_MEMORY_BARRIER (); p->lock = 0; // p is a generic struct with a TAS lock Use clib_atomic_release to generate more efficient assembly code.

2019-03-18vnet: disable the expansion of the heap allocated for classifier tablesAndrew Yourtchenko1-0/+2
Classifier data structures assume the contiguous chunk of memory within the heap. Default heap flags for dlmalloc allow for heap growth. When that happens, the memory becomes discontiguous. This results in symptoms that are more cryptic than necessary. Disabling the expand makes the session allocation behavior of the classifier the same for dlmalloc as for the legacy allocator.

2018-02-07classifier-based ACL: refactor + add output ACLAndrew Yourtchenko1-1/+1
For implementation of MACIP ACLs enhancement (VPP-1088), an outbound classifier-based ACL would be needed. There was an existing incomplete code for outbound ACLs, it looked almost exact copy of input ACLs, minus the various enhancements, trying to sync that code seemed error-prone and cumbersome to maintain in the longer run. This change refactors the input+output ACLs processing into a unified routine (thus any changes will have effect on both), and also adds the API to set the output interface ACL, with the same format and semantics as the existing input one (except working on output ACL of course). WARNING: IP outbound ACL in L3 mode clobbers the ip.* fields in the vnet_buffer_opaque_t, since the code is using l2_classify.* The net_buffer (p0)->ip.save_rewrite_length is rescued into l2_classify.pad.l2_len, and used to rewind the header in case of drop, so that ipX_drop prints something sensible.

2017-11-10add classify session action set-sr-policy-indexGabriel Ganne1-1/+9
This allows to use the classifier to steer source routing packets instead of using the "sr steer" command. This way we can steer on anything instead of only the dst ip address. test: * add add_node_next function to the VppPapiProvider class. * add simple test scenario using the classifier to steer packets with dest ip addr == a7::/8 to the source routing insert node. * use new interface indexes (3,4) instead of (0,1) to prevent a cleanup conflict with the other tests which attach a specific fib to the interface. The test creates interfaces sepsrated from the other tests to prevent a conflict in the cleaning of the ip6 fib index 1 which causes vpp not to be able to find a default route on this table.

2017-04-06Use thread local storage for thread indexDamjan Marion1-8/+8
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.
