2017-10-04[aarch64] Fixes CLI crashes on dpaa2 platform.Christophe Fontaine6-9/+9
- always use 'va_args' as pointer in all format_* functions - u32 for all 'indent' params as it's declaration was inconsistent Change-Id: Ic5799309a6b104c9b50fec309cba789c8da99e79 Signed-off-by: Christophe Fontaine <christophe.fontaine@enea.com>
2017-10-03Repair vlib API socket serverDave Barach10-40/+40
- Teach vpp_api_test to send/receive API messages over sockets - Add memfd-based shared memory - Add api messages to create memfd-based shared memory segments - vpp_api_test supports both socket and shared memory segment connections - vpp_api_test pivot from socket to shared memory API messaging - add socket client support to libvlibclient.so - dead client reaper sends ping messages, container-friendly - dead client reaper falls back to kill (<pid>, 0) live checking if e.g. a python app goes silent for tens of seconds - handle ping messages in python client support code - teach show api ring about pairwise shared-memory segments - fix ip probing of already resolved destinations (VPP-998) We'll need this work to implement proper host-stack client isolation Change-Id: Ic23b65f75c854d0393d9a2e9d6b122a9551be769 Signed-off-by: Dave Barach <dave@barachs.net> Signed-off-by: Dave Wallace <dwallacelf@gmail.com> Signed-off-by: Florin Coras <fcoras@cisco.com>

174267: Revisit this string termination issue 174816: Add check for NULL when trace is enabled 177211: Add notation that mutex is not required here 177117: Added check for log2_page_size == 0 and returns an error if so 163697,163698: Added missing sw_if_index validation Change-Id: I5a76fcf6505c785bfb3269e353360031c6a0fd0f Signed-off-by: Chris Luke <chrisy@flirble.org>
2017-09-19format_sockaddr: add trivial support for AF_LOCAL socketsDave Barach1-0/+12
There isn't anything useful to print. Return a unique name since the unix cli uses the returned string to create a node name. Node names must be unique, or vpp will quit abruptly. Change-Id: I8f85ae8fececdbfd26c729bc32c2c2007c06d1ea Signed-off-by: Dave Barach <dave@barachs.net>
2017-09-18Fixes for issues Coverity has reported (VPP-972)Chris Luke1-1/+1
177117: fstat() returns -1 on error; the code is checking for any positive value instead 175142: final return could never be reached; simple refactoring 175235,175236: Warning suppressed with an explicit cast to (void) 174817: Final return couldn't be reached; is is_in_order is 0 then 'rv' is already returned above 172095,172093: If is_is_set does not get set to 1, then return 0 has already been invoked 174405: Re-kill this (nothing sets rv) 171136: Looks like a cmd line flag to set test_bytes was missing; added it, and refactored the argc/argv processing to avoid two other potential segv's 176813: Add range checking for term width/height. First stab at a reasonable range is 1-512 for both. 175350: Fix implicit casting in shift operation 174272: Not a c+p error; try using a coverity annotation to ignore it 174273,175320: Annotated FORWARD_NULL Change-Id: I58d0f860fc2209f59f8d1b6b344d631b8d429ace Signed-off-by: Chris Luke <chrisy@flirble.org>

2017-07-19Add a bihash prefetchable bucket-level cacheDave Barach7-37/+320
According to Maciek, the easiest way to leverage the csit "performance trend" job is to actually merge the patch once verified. Manual testing indicates that the patch improves l2 path performance. Other use-cases are TBD. It's possible that we'll need to back out the patch depending on what happens.

2017-06-12Remove calls to crc_u32 and add clib_crc32c for armv8+crcChristophe Fontaine4-63/+35
crc_u32 was not defined for non x86_64 with SSE4.2 processors. Calls to "crc_u32" are removed and replaced by either a call to clib_crc32c or a call to clib_xxhash, as the result is not used as a check value but as a hash.

VPP crash is observed when MAC aging is enabled with multi-threaded mode. If a thread other-than-zero expands the working_copies vector, working_copy_lengths should be initialized with vec_validate_init_empty(..., -1) to fill -1 across lower-numbered working_copy_lengths vector element.

In the case where n is a constant 16 bytes, the second load/store is ignored by the load/store unit - it has neglible/zero cost. In the case where n is variable and greater than 512 bytes, the extra if (n == 16) branch has a very small performance impact.

2017-04-01Clean up event log merge codeDave Barach3-70/+276
Fix a decade-old ridiculous qsort function bug. Managed to subtract floating-point numbers as if they were integers, leading to manufactured time-paradoxes. That completely confuses g2, leading to the summary disappearance of entire tracks' worth of data at high zoom levels. Add a manual alignment tweak parameter to elog_merge, users can dial-out time paradoxes caused by NTP-grade clock synchronization. The event-logger has a precision of O(100ns), whereas NTP synchronization is O(1ms). Change-Id: I69dedabaa314f69f9df74ec9ee66e21e6c87f703 Signed-off-by: Dave Barach <dave@barachs.net>
