2020-10-26memif: handle unexpected EPOLLOUT for RX queueSteven Luong1-0/+12
Getting an unexpected EPOLLOUT for RX queue and crashing due to missing callback function on write_function to handle EPOLLOUT. (gdb) f 5 f 5 node=<optimized out>, vm=0x7f948bbe4540 <vlib_global_main>) at /vpp/src/vlib/unix/input.c:325 325 errors[n_errors] = f->write_function (f); (gdb) p *e p *e $21 = {events = 4, data = {ptr = 0x23, fd = 35, u32 = 35, u64 = 35}} (gdb) p file_main.file_pool[e->data.fd] p file_main.file_pool[e->data.fd] $22 = {file_descriptor = 37, flags = 1, polling_thread_index = 0, private_data = 65536, read_function = 0x7f944a87b140 <memif_int_fd_read_ready>, write_function = 0x0, error_function = 0x0, description = 0x7f944be22400 "memif0/1 rx 0 int", read_events = 0, write_events = 1, error_events = 0} (gdb) File descriptors are recycled. It is likely that the EPOLLOUT is meant for the previous owner of the same file descriptor number which memif recycled and memif RX did not expect to receive an EPOLLOUT. For defensive play, we create a dummy callback function to ignore the EPOLLOUT instead of crashing.

2020-08-27tests: "force solo" testcase supportAndrew Yourtchenko1-0/+4
Some of the tests are time-sensitive, and at present require a non-trivial modification in order to run at high concurrency. Without these modifications, they intermittently fail, and require the test retries. Rather than setting them to the extended tests and forgetting about them, put them into a "solo" set, which gets run in a single-threaded mode after the rest of the tests are done. Mark a few of the tests that showed errors during TEST_JOBS=48 as forced-solo. Also, give a better diagnostic if the testcase misses a docstring needed to represent it in the diagnostic outputs.

2019-09-16api: autogenerate api trace print/endianOle Troan1-0/+4
In addition to the external vppapitrace tool, VPP itself supports dumping of API trace files. In two formats, "custom-dump" and "dump". "dump" gives a human friendly list, and "custom-dump" is meant to give a list of commands that can be fed to VAT. This patch only deals with "dump". Prior to this fix, auto-generation was only done for the basic types. This fix adds support for any type, including lists, and supports pretty-printing of enums, strings, IP addresses, MAC addresses and so on.

2019-07-24memif: fix vector overflow when copying stringsBenoît Ganne1-19/+27
When memif sends back socket messages containing strings, we copy vectors into C-string. Unfortunately, most vectors are not null-terminated, causing strncpy() read overflow. Moreover, strncpy() does not null-terminate string in case of max length reached. This patch introduces helpers to safely copy strings from vectors.

2019-07-23api: binary api cleanupDave Barach2-3/+6
Multiple API message handlers call vnet_get_sup_hw_interface(...) without checking the inbound sw_if_index. This can cause a pool_elt_at_index ASSERT in a debug image, and major disorder in a production image. Given that a number of places are coded as follows, add an "api_visible_or_null" variant of vnet_get_sup_hw_interface, which returns NULL given an invalid sw_if_index, or a hidden sw interface: - hw = vnet_get_sup_hw_interface (vnm, sw_if_index); + hw = vnet_get_sup_hw_interface_api_visible_or_null (vnm, sw_if_index); if (hw == NULL || memif_device_class.index != hw->dev_class_index) return clib_error_return (0, "not a memif interface"); Rename two existing xxx_safe functions -> xxx_or_null to make it obvious what they return.

2019-07-18vlib: convert frame_index into real pointersAndreas Schultz1-1/+1
The fast path almost always has to deal with the real pointers. Deriving the frame pointer from a frame_index requires a load of the 32bit frame_index from memory, another 64bit load of the heap base pointer and some calculations. Lets store the full pointer instead and do a single 64bit load only. This helps avoiding problems when the heap is grown and frames are allocated below vm->heap_aligned_base.

2019-07-09vat: unload unused vat pluginsDave Barach1-2/+4
If the corresponding vpp plugin is absent, return a non-zero clib_error_t * from vat_plugin_register ("xxx plugin not loaded"). The vat plugin calls dlclose on the vat plugin, and it disappears. Depending on the plugin configuration, this can reduce the vpp virtual size by several gigabytes. Added a VAT_PLUGIN(<plugin-name>) macro to vat_helper_macros, clean up boilerplate vat_plugin_register() implementations. Fixed a number of non-standard vat_plugin_register methods.

-fno-common makes sure we do not have multiple declarations of the same global symbol across compilation units. It helps debug nasty linkage bugs by guaranteeing that all reference to a global symbol use the same underlying object. It also helps avoiding benign mistakes such as declaring enum as global objects instead of types in headers (hence the minor fixes scattered across the source).
