* Add linux compatibility testsBrian Behlendorf2011-06-211-0/+1
| | | | | | | | | | | | | | | | | | | | | While the splat tests were originally designed to stress test the Solaris primatives. I am extending them to include some kernel compatibility tests. Certain linux APIs have changed frequently. These tests ensure that added compatibility is working properly and no unnoticed regression have slipped in. Test 1 and 2 add basic regression tests for shrink_icache_memory and shrink_dcache_memory. These are simply functional tests to ensure we can call these functions safely. Checking for correct behavior is more difficult since other running processes will influence the behavior. However, these functions are provided by the kernel so if we can successfully call them we assume they are working correctly. Test 3 checks that shrinker functions are being registered and called correctly. As of Linux 3.0 the shrinker API has changed four different times so I felt the need to add a trivial test case to ensure each variant works as expected.
* Add zlib regression testBrian Behlendorf2011-02-251-0/+1
| | | | | | | | | A zlib regression test has been added to verify the correct behavior of z_compress_level() and z_uncompress. The test case simply takes a 128k buffer, it compresses the buffer, it them uncompresses the buffer, and finally it compares the buffers after the transform. If the buffers match then everything is fine and no data was lost. It performs this test for all 9 zlib compression levels.
* Public Release PrepBrian Behlendorf2010-05-171-17/+15
| | | | | | Updated AUTHORS, COPYING, DISCLAIMER, and INSTALL files. Added standardized headers to all source file to clearly indicate the copyright, license, and to give credit where credit is due.
* Add basic credential support and splat tests.Brian Behlendorf2009-07-271-0/+1
| | | | | | | | | | | | | | | | | | | The previous credential implementation simply provided the needed types and a couple of dummy functions needed. This update correctly ties the basic Solaris credential API in to one of two Linux kernel APIs. Prior to 2.6.29 the linux kernel embeded all credentials in the task structure. For these kernels, we pass around the entire task struct as if it were the credential, then we use the helper functions to extract the credential related bits. As of 2.6.29 a new credential type was added which we can and do fairly cleanly layer on top of. Once again the helper functions nicely hide the implementation details from all callers. Three tests were added to the splat test framework to verify basic correctness. They should be extended as needed when need credential functions are added.
* SLES10 Fixes (part 9)Brian Behlendorf2009-05-211-23/+39
| | | | | | | | | | | - Proper ioctl() 32/64-bit binary compatibility. We need to ensure the ioctl data itself is always packed the same for 32/64-bit binaries. Additionally, the correct thing to do is encode this size in bytes as part of the command using _IOC_SIZE(). - Minor formatting changes to respect the 80 character limit. - Move all SPLAT_SUBSYSTEM_* defines in to splat-ctl.h. - Increase SPLAT_SUBSYSTEM_UNKNOWN because we were getting close to accidentally using it for a real registered subsystem.
* SLES10 Fixes (part 7)Brian Behlendorf2009-05-201-1/+1
| | | | | | | | | | | - Initial SLES testing uncovered a long standing bug in the debug tracing. The tcd_for_each() macro expected a NULL to terminate the trace_data[i] array but this was only ever true due to luck. All trace_data[] iterators are now properly capped by TCD_TYPE_MAX. - SPLAT_MAJOR 229 conflicted with a 'hvc' device on my SLES system. Since this was always an arbitrary choice I picked something else. - The HAVE_PGDAT_LIST case should set pgdat_list_addr to the value stored at the address of the memory location returned by kallsyms_lookup_name().
* Coverity 9641: Buffer SizeBrian Behlendorf2009-02-171-1/+1
| | | | | | When SPLAT_TEST_INIT() initialized SPLAT_KMEM_TEST11_NAME the short short test name overran the static length buffer of SPLAT_NAME_SIZE. This was fixed by increasing the buffer length from 16 to 20 bytes.

| | | | | | | | | | | | | | | | | ensure I never add anything to the stack I don't absolutely need. All this debug code could be removed from a production build anyway so I'm not so worried about the performance impact. We may also consider revisting the mutex and condvar implementation to ensure no additional stack is used there. Initial indications are I have reduced the worst case stack usage to 9080 bytes. Still to large for the default 8k stacks so I have been forced to run with 16k stacks until I can reduce the worst offenders. git-svn-id: https://outreach.scidac.gov/svn/spl/trunk@83 7e1ea52c-4ff2-0310-8f11-9dd32ca42a1c
