2019-07-23vlib: address vlib_error_t scaling issueDave Barach1-1/+8
Encoding the vpp node index into the vlib_error_t as a 10-bit quantity limits us to 1K graph nodes. Unfortunately, a few nodes need 6 bit per-node error codes. Only a very few nodes have so many counters. It turns out that there are about 2K total error counters in the system, which is (approximately) the maximum error heap index. The current (index,code) encoding limits the number of interfaces to around 250, since each interface has two associated graph nodes and we have about 500 "normal, interior" graph node This patch adds an error-index to node-index map, so we can store error heap indices directly in the vlib_buffer_t.

2019-07-22stats: fix use-after-free hash key stringBenoît Ganne1-3/+6
Hash keys are not copied by the hash infrastructure, instead the pointer is used directly. stat_segment_register_gauge() does not allocate a private object for the key, causing issues when it is freed or reused. Allocate a private object on insertion into the hashtable instead. Type: fix Fixes: 92e3082199d10add866894e86a9762d79a3536c4 Change-Id: Ifb6addfcaec81bdb7ea3512050ce55f06ef09a4c Signed-off-by: Benoît Ganne <bganne@cisco.com>
2019-06-18stats: fix memory leakage when adding / deleting interfacesOle Troan1-1/+1
This fixes two leaks in registering errors in the stats segment. - The error name created by vlib_register_errors() was not freed. - Duplicate error names (when interface readded) was added to the vector. This fix also adds memory usage statistics for the statistics segment as /mem/statseg/{used, total} Change-Id: Ife98d5fc5baef5bdae426a5a1eef428af2b9ab8a Type: fix Signed-off-by: Ole Troan <ot@cisco.com>
2019-05-22stats: support multiple works for error countersOle Troan1-17/+3
The current code only allowed access to the main thread error counters. That is not so useful for a multi worker instance. No return a vector indexed by thread of counter_t values. Type: fix Change-Id: Ie322c8889c0c8175e1116e71de04a2cf453b9ed7 Signed-off-by: Ole Troan <ot@cisco.com>

2018-11-13vlib rename vlib_frame_args(...) to vlib_frame_scalar_args(..)Damjan Marion1-1/+1
Typically we have scalar_size == 0, so it doesn't matter but vlib_frame_args was providing pointer to scalar frame data, not vector data. To avoid future confusion function is renamed to vlib_frame_scalar_args(...) Change-Id: I48b75523b46d487feea24f3f3cb10c528dde516f Signed-off-by: Damjan Marion <damarion@cisco.com>

2018-09-17STATS: Dynamically mapped shared memory segmentOle Troan1-3/+5
Move from using a hash to a vector with offsets into shared memory. Limit exposure of VPP data structures and include files to external stats library and applications. Change-Id: Ic06129f12d10cf4c4946a86d9bc734eacff2c7da Signed-off-by: Ole Troan <ot@cisco.com>

2018-06-15STATS: Add more hierarchy to counters.Ole Troan1-1/+1
Put error counters under node_index. /err/<node-name>/<error-name> E.g: /err/ip4-lookup/Hash table collisions /err/ip6-rewrite/Buffer allocation error Error names are not globally unique, and this allows for walking all errors for a particular node. Put interface counters under the directory /if. E.g. /if/rx Put system counters under the directory /sys. E.g. /sys/vector_rate Change-Id: I5b794d16698f61bcb2063a8cd77a7c4ae36419b8 Signed-off-by: Ole Troan <ot@cisco.com>

2017-04-06Use thread local storage for thread indexDamjan Marion1-1/+1
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.
