2020-03-18ethernet: Copy only 6 bytes of mac address into a u64Jon Loeliger1-3/+3
Rather than leaving 2 bytes of junk in the upper word of a mac address represented as a u64, zero them out. That way later compairsons stand a chance of matching when deleting a bridge's arp termination entries. The volatile qualifier shouldn't be needed here, but without it the compiler removes the clib_memcpy() at -O2. Bad compiler. No biscuit.

2019-11-26fib: Table ReplaceNeale Ranns2-37/+0
Type: feature from the API doc, a table replace is: " The use-case is that, for some unspecified reason, the control plane has a very different set of entries it wants in the table than VPP currently has. The CP would thus like to 'replace' VPP's current table only by specifying what the new set of entries shall be, i.e. it is not going to delete anything that already eixts. the CP delcartes the start of this procedure with this begin_replace API Call, and when it has populated all the entries it wants, it calls the below end_replace API. From this point on it is of coursce free to add and delete entries as usual. The underlying mechanism by which VPP implements this replace is purposefully left unspecified. " In the FIB, the algorithm is implemented using mark and sweep. Algorithm goes: 1) replace_begin: this marks all the entries in that table as 'stale' 2) download all the entries that should be in this table - this clears the stale flag on those entries 3) signal the table converged: ip_table_replace_end - this removes all entries that are still stale this procedure can be used when an agent first connects to VPP, as an alternative to dump and diff state reconciliation.

2019-09-16api: autogenerate api trace print/endianOle Troan2-1/+28
In addition to the external vppapitrace tool, VPP itself supports dumping of API trace files. In two formats, "custom-dump" and "dump". "dump" gives a human friendly list, and "custom-dump" is meant to give a list of commands that can be fed to VAT. This patch only deals with "dump". Prior to this fix, auto-generation was only done for the basic types. This fix adds support for any type, including lists, and supports pretty-printing of enums, strings, IP addresses, MAC addresses and so on.

2019-05-16init / exit function orderingDave Barach4-30/+28
The vlib init function subsystem now supports a mix of procedural and formally-specified ordering constraints. We should eliminate procedural knowledge wherever possible. The following schemes are *roughly* equivalent: static clib_error_t *init_runs_first (vlib_main_t *vm) { clib_error_t *error; ... do some stuff... if ((error = vlib_call_init_function (init_runs_next))) return error; ... } VLIB_INIT_FUNCTION (init_runs_first); and static clib_error_t *init_runs_first (vlib_main_t *vm) { ... do some stuff... } VLIB_INIT_FUNCTION (init_runs_first) = { .runs_before = VLIB_INITS("init_runs_next"), }; The first form will [most likely] call "init_runs_next" on the spot. The second form means that "init_runs_first" runs before "init_runs_next," possibly much earlier in the sequence. Please DO NOT construct sets of init functions where A before B actually means A *right before* B. It's not necessary - simply combine A and B - and it leads to hugely annoying debugging exercises when trying to switch from ad-hoc procedural ordering constraints to formal ordering constraints.

'%x' unformat specifier expects a pointer to a 4-byte object and will overflow when using a pointer to a 1-byte object. Use '%X' instead which allows to pass the size of the object alongside its pointer. The bug was exposed with the following commands: ~# make run DBGvpp# loop create loop0 DBGvpp# set ip6 neigh loop0 3001::2 a:a:a:a:a:a DBGvpp# show ip6 neigh Time Address Flags Link layer Interface 35.7743 ::2 D 0a:0a:0a:0a:0a:0a loop0 ^^^ wrong address: should be 3001::2 Note that the bug impact depends from the parsing order and memory layout.

It is causing compilation sloness with gcc-7 so removing it before it was originally planned. So far macros are left in the tree so we can know which nodes to convert to new multiarch code. Change-Id: Idb14622ca61fdce1eba59723b20d98715b7971e6 Signed-off-by: Damjan Marion <damarion@cisco.com>
