* Allow CONFIG_foo COMPARISON-OP number in preprocessor conditionals.Mark Wielaard2010-02-192-12/+51
| | | | | | * parse.cxx (eval_pp_conditional): Handle r->type == tok_number when l->type == tok_identifier. * testsuite/semok/config_number.stp: New test.
* PR11296: switch to "sys/sdt.h" in test casesFrank Ch. Eigler2010-02-1814-18/+18

* Restore redirection of the stdout of stap-serverd to /dev/nullDave Brolley2010-02-171-1/+1

* Improved server certificate management. ulimit for stap-server only.Dave Brolley2010-02-175-47/+85
| | | | | | | - Server now generates a new certificate when old one expires. - Certificates now valid for 1 year. - ulimit for stap-server-connect now only set for stap-server user and only when override variable is not set.
* Use clamping to more easily normalize input valuesJosh Stone2010-02-165-20/+25
| | | | | | The kernel has min/max/clamp macros to make range comparisons easier. Clamp is a newer invention, but we can define it for older kernels in terms of min and max.
* PR11282: Keep the md4 state in the hash copy constructorJosh Stone2010-02-161-1/+1
| | | | | | | | We were getting new hash collisions, because the new hash copy constructor was restarting the md4 computation. Everything from get_base_hash was thus lost. * hash.h (hash::hash): Keep the md4 state when copying.
* PR11277: Use consistent octal in quoted stringsJosh Stone2010-02-163-33/+26
| | | | | | | | | | Previously, our octal escapes used variable lengths, which can lead to ambiguities. Also, 8-bit characters would only output the least digit. * runtime/string.c (_stp_text_str): Always output 3-digit octal escapes, and handle 8-bit chars more gracefully. * testsuite/systemtap.string/text_str.stp: Include an 8-bit character. * testsuite/systemtap.string/text_str.exp: Above + expect 3-digit octal.
* Don't try to parallel install partial build-elfutils build in lib-elfutils.Mark Wielaard2010-02-1613-2663/+4845
| | | | | | | | | | | | | | | | | | | The parallel install into lib-elfutils during the build seems to be fragile, so explicitly install the libs with -j1. * Makefile.am (stamp-elfutils): Add -j1 in for dir loop sub make. * Makefile.in: Regenerated. * aclocal.m4: Likewise. * compile: Likewise. * config.in: Likewise. * configure: Likewise. * doc/Makefile.in: Likewise. * doc/SystemTap_Tapset_Reference/Makefile.in: Likewise. * doc/beginners/Makefile.in: Likewise. * grapher/Makefile.in: Likewise. * testsuite/Makefile.in: Likewise. * testsuite/aclocal.m4: Likewise. * testsuite/configure: Likewise.

| * PR11281 Allow negative values for -D argument.Mark Wielaard2010-02-141-1/+1
| | | | | | | | | | | | | | Change regexp match to "^[a-z_][a-z_0-9]*(=-?[a-z_0-9]+)?$". * main.cxx (main): case 'D' allow optional single minus sign after equal in assert_regexp_match().
| * Test for sendfile syscall can handle non-socket fds now.Mark Wielaard2010-02-131-4/+4
| | | | | | | | | | | | | | | | Since 2.6.33 sendfile can handle non-socket fds, so make the test handle both success and failure. * testsuite/systemtap.syscall/sendfile.c (main): Make buffer 22 bytes, since 22 == EINVAL, test for 22 bytes send or -22 failure.

| * PR11105 part 2: tighten constraints on stap-server parameters passed to makeFrank Ch. Eigler2010-02-126-56/+101
| | | | | | | | | | | | | | * util.h, util.cxx (assert_match_regexp): New function. * main.cxx (main): Constrain -R, -r, -a, -D, -S, -q, -B flags. * stap-serverd (listen): Harden stap-server-connect with ulimit/loop. * testsuite/systemtap.server/{client,server}_args.exp: Revised.
| * Add simple test for PR10257 (sprint(@hist_linear)).Przemysław Pawełczyk2010-02-112-0/+18
| | | | | | | | | | | | | | | | | | | | Test is simple, because print and sprint uses the same code for handling @hist_* and it is not intended for playing with MAXSTRINGLEN, which is required anyway for bigger histograms (the one generated here consists of only 127 characters). When PR10690 (need way to produce bigger procfs output) will be fixed, then we should add another test for both PRs with normal histogram.
| * Fixed PR 11270 by adding nd_syscall testcase.David Smith2010-02-104-2/+99
| | | | | | | | | | | | | | | | | | | | * testsuite/systemtap.syscall/test.tcl: Now uses global variable 'test_script' to find test script to run. * testsuite/systemtap.syscall/syscall.exp: Sets test_script. * testsuite/systemtap.syscall/nd_sys.stp: New test script. Copy of sys.stp, but uses nd_syscall probes. * testsuite/systemtap.syscall/nd_syscall.exp: New testcase. Copy of syscall.exp, but uses nd_sys.stp test script.

| | * rhbz#563114 Make syscall.pipe sys32_pipe probe alias optional on x86_64.Mark Wielaard2010-02-091-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Some distributions might have backported the pipe fd leak patch and removed the sys32_pipe kernel function even before 2.6.32. So make the probe alias optional instead of relying on a version check. * tapset/x86_64/syscalls.stp (syscall.pipe): Make alias optional. (syscall.pipe.return): Likewise.
| * | Fix tcl.exp initialization bugStan Cox2010-02-091-0/+1

| * Fixed BZ559643 by doing 'spawn;expect;wait' instead of 'spawn;wait;expect'.David Smith2010-02-081-17/+26
| | | | | | | | | | | | * testsuite/systemtap.base/labels.exp: Corrected order of 'spawn;expect;wait' calls. Added 'wait' calls when needed. Also, doesn't run the "labels exe .label" test if uprobes isn't supported.
* | Rework identification of probes allowed for unprivileged users.Dave Brolley2010-02-1517-96/+205
|/ | | | | | | - Bind unprivileged permission at probe registration time. - Remove check_unprivileged filter from derived_probe_builder and its children. - Add test suites for unprivilegedok and unprivilegedko.

| | | | | | | | | | | | We now implement __get_argv's string building in pure stap script. Also, every argument is now quoted, which is different than before, but it's much more robust about handling special characters.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ideas from Frank Ch. Eigler: - extending the hash.add() function to pass names along with the hash-mix values, so that class hash can internally track the hash-report string - storing the reports themselves in the cache, beside the .ko / .c files, and changing the cache-size-limit logic to delete these .txt files upon garbage collection * hash.h : New member parm_stream. * hash.cxx (get_parms): New function to convert parms stream to string. (hash::add): Aggregrate parms stream. (create_hash_log): New function to log hash operation.
