2018-06-17acl-plugin: fix the high cpu usage caused by the connection cleanerAndrew Yourtchenko1-1/+2
The commit 4bc1796b346efd10f3fb19b176ff089179263a24 had incorrect calculation of the session lists minimal timeout, resulting in returned value of 0 which resulted in existing sessions constantly requeued, taking up the CPU. Fix this calculation. Change-Id: I9a789739f96a1f01522c68f91b0a02db2417837f Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
2018-06-17acl-plugin: split (L3) and (L4/pkt) logic of creation of 5tuple structure, ↵Andrew Yourtchenko1-46/+70
optimize stores in the (l4/pkt) Having two pieces of code - one for now much simpler to recreate L3 info, one for a more difficult do build L4/pkt metadata allows more degrees of freedom for optimizations. Also, construct the metadata in local variables first before saving it into the memory structure, this fewer memory stores and they are better aligned, allowing to coalesce with subsequent reads if needed.

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.

2018-06-15NAT44: endpoint dependent mode (VPP-1273)Matus Fabian9-1454/+3499
To enable NAT plugin endpoint dependent mode add following to statrup config: nat { endpoint-dependent } Enable endpoint dependent filtering and mapping for all sessions. Move some existing functionality such as service load balancing, twice nat, out2in-only static mappings and unknown protocol dynamic translations, which use endpoint dependent lookup hash tables before. Basically split to vanilla NAT44 and extra features NAT44. Change-Id: I3925eb5ddcc8f1ec4cf6af4e2a618a7ec7aa9735 Signed-off-by: Matus Fabian <matfabia@cisco.com>

2018-06-14acl-plugin: VAT: add an option to load entire ACL from a ClassBench ruleset ↵Andrew Yourtchenko1-0/+190
file for testing Add a command "acl_add_replace_from_file" to VAT which can load a ruleset and add an ACL with it. There are a few options which augment the ACL being created: "permit+reflect" or "permit" alter the default action from deny on the ACEs created. "append-default-permit" adds an entry in the end with the "permit+reflect" if the default action has been changed to permit+reflect, or with a simple permit otherwise. This command is IPv4-only because the available datasets were IPv4-only. Change-Id: I26b9f33ecb6b59e051d1d9cbafedbc47e8203392 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>

2018-06-13acl-plugin: change the src/dst L3 info in 5tuple struct to be always ↵Andrew Yourtchenko6-97/+156
contiguous with L4 data Using ip46_address_t was convenient from operational point of view but created some difficulties dealing with IPv4 addresses - the extra 3x of u32 padding are costly, and the "holes" mean we can not use the smaller key-value data structures for the lookup. This commit changes the 5tuple layout for the IPv4 case, such that the src/dst addresses directly precede the L4 information. That will allow to treat the same data within 40x8 key-value structure as a 16x8 key-value structure starting with 24 byte offset.

2018-06-13cli: 'restart' should close open files (VPP-1068)Chris Luke1-2/+17
- On 'restart' close all registered files (except stdio) so that the new process has a clean start; in particular, CLI sockets, API sockets, tun/af_packet etc descriptors all need to close so they're not left open but unused by the new VPP process. To do this we iterate all the files registered for the polling mechanism and close() them.[1] - While we're here, retain the original environment on 'restart'; several things make use of it. [1] An alternative mechanism would be to mark all files with CLOEXEC on opening; I think that is a little fragile for this fairly esoteric use case.

2018-06-10cli: Fix reverse-line-wrap in terminals (VPP-1295)Chris Luke1-86/+195
- Terminals do not reverse-line-wrap when the cursor is at the left edge and \b tries to make it go left. - Instead, we have to track the cursor position if we need to emit \b's and if we are at the left edge emit an ANSI sequence to relocate the cursor. Previously we usually simply calculated the new cursor position after a bunch of output had completed. - Further trickiness is required since most xterm-like terminals also defer moving the cursor to the next line when at the right edge[1], and then if they receive a \b move the cursor back one character too many. - This requires intricate reworking of everywhere that \b is emitted by the CLI code during command line editing. [1] Bash counters this issue by tracking the cursor position as output is generated and forcing the cursor to the next line (by emitting a space followed by \r) if it gets to this phantom cursor position); here we effectively do that but only if the user tries to go left when in this state.
