* dtrace: avoid gcc9 Walloca-larger-thanRyan Libby2019-12-211-21/+47
| | | | | | | | | | | | gcc9 grew a new warning for unbounded allocas, such as the one in dt_options_load. Remove both uses of alloca in dt_options.c. Reviewed by: markj Sponsored by: Dell EMC Isilon Differential Revision: https://reviews.freebsd.org/D22880 Notes: svn path=/head/; revision=355973
* Fix an off-by-one in dt_opt_setenv().Mark Johnston2018-01-101-9/+10
| | | | | | | | | | | | The bug would cause incorrect behaviour when attempting to override an already set environment variable with -x setenv, as long as the variable is not the last one in the array.

* Remove drti.o's dependency on libelf. This makes it possible to add DTraceMark Johnston2015-02-181-0/+25
| | | | | | | | | | | | | | | | | | | | | | probes to userland programs and libraries without also needing to link libelf. dtrace -G places the __SUNW_dof symbol at the beginning of the DOF (DTrace probe and provider metdata) section in the generated object file; drti.o now just uses this symbol to locate the section. A complication occurs when multiple dtrace-generated object files are linked together, since the __SUNW_dof symbol defined in each file is global. This is handled by using objcopy(1) to convert __SUNW_dof to a local symbol once drti.o has been linked with the generated object file. Upstream, this is done using a linker feature not present in GNU ld.

* Mechanically convert cddl sun #ifdef's to illumosSteven Hartland2015-01-171-3/+3
| | | | | | | | | | | | | | | Since the upstream for cddl code is now illumos not sun, mechanically convert all sun #ifdef's to illumos #ifdef's which have been used in all newer code for some time. Also do a manual pass to correct the use if #ifdef comments as per style(9) as well as few uses of #if defined(__FreeBSD__) vs #ifndef illumos.

| | | | | | | | | | | | | | illumos/illumos-gate@6fb4854bed54ce82bd8610896b64ddebcd4af706 This fixes the tst.resize1.d and tst.resize2.d DTrace tests, which have been failing since r261122 since they were causing dtrace(1) to attempt to allocate and use large amounts of memory, and get killed by the OOM killer as a result.

* Bring back part of r249367 by adding DTrace's temporal option, which allowsMark Johnston2013-05-121-1/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | users to guarantee that the output of DTrace scripts will be time-ordered. This option is enabled by adding the line #pragma D option temporal to the beginning of a script, or by adding '-x temporal' to the arguments of dtrace(1). This change fixes a bug in the original port of the temporal option. This bug was causing some assertions to fail, so they had been disabled; in this revision the assertions are working properly and are enabled. The DTrace version number has been bumped from 1.9.0 to 1.9.1 to reflect the language change that's being introduced. This change corresponds to part of illumos-gate commit e5803b76927480: 3021 option for time-ordered output from dtrace(1M) Reviewed by: pfg Obtained from: illumos MFC after: 1 month Notes: svn path=/head/; revision=250574
* DTrace: Revert r249367Pedro F. Giffuni2013-04-171-62/+1
| | | | | | | | | | | | | | | | | | | | | | | | | The following change from illumos brought caused DTrace to pause in an interactive environment: 3026 libdtrace should set LD_NOLAZYLOAD=1 to help the pid provider This was not detected during testing because it doesn't affect scripts. We shouldn't be changing the environment, especially since the LD_NOLAZYLOAD option doesn't apply to our (GNU) ld. Unfortunately the change from upstream was made in such a way that it is very difficult to separate this change from the others so, at least for now, it's better to just revert everything.

* DTrace: option for time-ordered outputPedro F. Giffuni2013-04-111-1/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge changes from illumos: 3021 option for time-ordered output from dtrace(1M) 3022 DTrace: keys should not affect the sort order when sorting by value 3023 it should be possible to dereference dynamic variables 3024 D integer narrowing needs some work 3025 register leak in D code generation 3026 libdtrace should set LD_NOLAZYLOAD=1 to help the pid provider This brings yet another feature implemented in upstream DTrace. A complete description is available here: http://dtrace.org/blogs/ahl/2012/07/28/my-new-dtrace-favorite/ This change bumps the DT_VERS_* number to 1.9.1 in accordance to what is done in illumos. This change was somewhat complicated because upstream is mixed many changes in an individual commit and some of the tests don't really apply to us. There are also appear to be differences in timestamping with Solaris so we had to workaround some assertions making sure no regression happened. Special thanks to Fabian Keil for changes and testing.
