2019-03-18Fix build with newer linux headersDamjan Marion1-2/+4

2019-01-01Default huge page size to the regular page sizeDave Barach1-0/+6
With this simple tweak, vpp is OK for "make test" or non-dpdk driver operation over a kernel which doesn't support hugepages at all. Tested on a Raspberry-pi 3B+ running the Ubuntu 18.04 64-bit server beta image. It's amazing that such a minimal system will not only self-compile vpp, but also run the unit tests. It's slow, but what do you expect for that amount of money? Change-Id: I7f080f871c828cc4b44be13809495278fadbd717 Signed-off-by: Dave Barach <dave@barachs.net>

2018-03-06glibc 2.27 fixMarco Varlese1-0/+2
With glibc 2.27 the memfd_create has been added to the devel libraries. That's causing the internally defined static function to clash with the system wide one. This patch addresses that issue on systems with latest glibc libraries. Change-Id: I788bf49b23d5b5f1cb1c0374e243d8a429178a71 Signed-off-by: Marco Varlese <marco.varlese@suse.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>
2017-09-18Fixes 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>
