2018-08-13Multiarch handling in different constructor macrosDamjan Marion3-0/+46
This significantly reduces need for ... in multiarch code. Simply constructor macros will jost create static unused entry if CLIB_MARCH_VARIANT is defined and that will be optimized out by compiler.

2018-07-12Fix debug CLI node recycling bugsDave Barach1-5/+26
When creating a new - as opposed to recycled - debug CLI process node, perform a proper barrier sync and node runtime update. Otherwise, the graph replicas diverge for some period of time. That's not immediately fatal, but it's not a good idea, either. When renaming a debug cli process node, fix all of the name-vector replicas before freeing the [one-and-only] name vector. This fixes the so-called stats segment node runtime scraper crash, which tripped over a replicated dangling reference to the recently-freed debug CLI node name.

2018-06-30cli: Validate cli_file_index on quit commandSteve Shin1-0/+4
VPP crash happens with 'vppctl quit quit' command. The 2nd quit command tries to access the file index which is already freed by the first quit. This can be avoided to validate cli_file_index. Change-Id: I880514c93523db2a727d7510c97950582cd6a6c8 Signed-off-by: Steve Shin <jonshin@cisco.com>
2018-06-27gcc8 and Wstringop-truncationMarco Varlese1-2/+4
gcc8 introduced a new warning (Wstringop-truncation) which in our case is being treated as error. Disabling the warning globally might introduce bugs related to string truncation which are not desired by the developer (e.g. bug). Instead, this patch disables the warning only for those occurences which have been verified to be non-bugs but the desired behaviour as per developer will.

2018-06-26add backtrace in unix_signal_handlerKingwel Xie1-9/+49
crash stack backtrace will be directed to syslog 1. make use of glic backtrace in execinfo.h. the old clib_backtrace is removed 2. install SIGABRT in signal handler, but have to remove it when backtrace is done. reason is to capture stack trace caused by SIGABRT. vPP ASSERT always call os_exit then abort(). we definitely want to know the trace of this situation. It is a little tricky to avoid SIGABRT infinite loop 3. always load symbols by calling clib_elf_main_init () in main(). Otherwise, PC addresses instead of symbols will be displayed.

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.

2018-06-13cli: '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: Disable XON/XOFF in the ttyChris Luke1-0/+4

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.

if you plan to put a hash into shared memory, the key sum and key equal functions MUST be set to constants such as KEY_FUNC_STRING, KEY_FUNC_MEM, etc. -lvppinfra is PIC, which means that the process which set up the hash won't have the same idea where the key sum and key compare functions live in other processes.

2018-04-26vlib: set log tap level <level> does not work for some keywordsSteven1-2/+2
While some levels such as debug and emerg work, others don't. See below. DBGvpp# set log class tap level warn set log class tap level warn set logging class: unknown input `level warn' DBGvpp# set log class tap level debug set log class tap level debug DBGvpp# set log class tap level info set log class tap level info set logging class: unknown input `level info' DBGvpp# set log class tap level err set log class tap level err DBGvpp# set log class tap level crit set log class tap level crit set logging class: unknown input `level crit' DBGvpp# set log class tap level emerg set log class tap level emerg DBGvpp# Cause: The reason for the failure for the shorter keywords is level_str is unformatted with %v which is not null terminated. For example, the character after "info" could be anything in level_str. The memcmp with size of the macro keyword __##uc which includes the null character or 5 in this case and thus the comparison fails. Fix: Use %s which insure level_str is null terminated. Use strcmp to rule out false positve match like "debugxxx" against keyword "debug". Change-Id: I7a2d97a0f7f618df105da7eca791618dce04d21e Signed-off-by: Steven <sluong@cisco.com>
