elf: Testing infrastructure for ld.so DSO sorting (BZ #17645)
|
||
|
|
|
||
|
|
This is the first of a 2-part patch set that fixes slow DSO sorting behavior in
|
||
|
|
the dynamic loader, as reported in BZ #17645. In order to facilitate such a
|
||
|
|
large modification to the dynamic loader, this first patch implements a testing
|
||
|
|
framework for validating shared object sorting behavior, to enable comparison
|
||
|
|
between old/new sorting algorithms, and any later enhancements.
|
||
|
|
|
||
|
|
This testing infrastructure consists of a Python script
|
||
|
|
scripts/dso-ordering-test.py' which takes in a description language, consisting
|
||
|
|
of strings that describe a set of link dependency relations between DSOs, and
|
||
|
|
generates testcase programs and Makefile fragments to automatically test the
|
||
|
|
described situation, for example:
|
||
|
|
|
||
|
|
a->b->c->d # four objects linked one after another
|
||
|
|
|
||
|
|
a->[bc]->d;b->c # a depends on b and c, which both depend on d,
|
||
|
|
# b depends on c (b,c linked to object a in fixed order)
|
||
|
|
|
||
|
|
a->b->c;{+a;%a;-a} # a, b, c serially dependent, main program uses
|
||
|
|
# dlopen/dlsym/dlclose on object a
|
||
|
|
|
||
|
|
a->b->c;{}!->[abc] # a, b, c serially dependent; multiple tests generated
|
||
|
|
# to test all permutations of a, b, c ordering linked
|
||
|
|
# to main program
|
||
|
|
|
||
|
|
(Above is just a short description of what the script can do, more
|
||
|
|
documentation is in the script comments.)
|
||
|
|
|
||
|
|
Two files containing several new tests, elf/dso-sort-tests-[12].def are added,
|
||
|
|
including test scenarios for BZ #15311 and Redhat issue #1162810 [1].
|
||
|
|
|
||
|
|
Due to the nature of dynamic loader tests, where the sorting behavior and test
|
||
|
|
output occurs before/after main(), generating testcases to use
|
||
|
|
support/test-driver.c does not suffice to control meaningful timeout for ld.so.
|
||
|
|
Therefore a new utility program 'support/test-run-command', based on
|
||
|
|
test-driver.c/support_test_main.c has been added. This does the same testcase
|
||
|
|
control, but for a program specified through a command-line rather than at the
|
||
|
|
source code level. This utility is used to run the dynamic loader testcases
|
||
|
|
generated by dso-ordering-test.py.

+"""Generate testcase files and Makefile fragments for DSO sorting test
|
||
|
|
+
|
||
|
|
+This script takes a small description string language, and generates
|
||
|
|
+testcases for displaying the ELF dynamic linker's dependency sorting
|
||
|
|
+behavior, allowing verification.
|
||
|
|
+
|
||
|
|
+Testcase descriptions are semicolon-separated description strings, and
|
||
|
|
+this tool generates a testcase from the description, including main program,
|
||
|
|
+associated modules, and Makefile fragments for including into elf/Makefile.
|
||
|
|
+
|
||
|
|
+This allows automation of what otherwise would be very laborous manual
|
||
|
|
+construction of complex dependency cases, however it must be noted that this
|
||
|
|
+is only a tool to speed up testcase construction, and thus the generation
|
||
|
|
+features are largely mechanical in nature; inconsistencies or errors may occur
|
||
|
|
+if the input description was itself erroneous or have unforeseen interactions.
|
||
|
|
+
|
||
|
|
+The format of the input test description files are:
|
||
|
|
+
|
||
|
|
+ # Each test description has a name, lines of description,
|
||
|
|
+ # and an expected output specification. Comments use '#'.
|
||
|
|
+ testname1: <test-description-line>
|
||
|
|
+ output: <expected-output-string>
|
||
|
|
+
|
||
|
|
+ # Tests can be marked to be XFAIL by using 'xfail_output' instead
|
||
|
|
+ testname2: <test-description-line>
|
||
|
|
+ xfail_output: <expected-output-string>
|
||
|
|
+
|
||
|
|
+ # A default set of GLIBC_TUNABLES tunables can be specified, for which
|
||
|
|
+ # all following tests will run multiple times, once for each of the
|
||
|
|
+ # GLIBC_TUNABLES=... strings set by the 'tunable_option' command.
|
||
|
|
+ tunable_option: <glibc-tunable-string1>
|
||
|
|
+ tunable_option: <glibc-tunable-string2>
|
||
|
|
+
|
||
|
|
+ # Test descriptions can use multiple lines, which will all be merged
|
||
|
|
+ # together, so order is not important.
|
||
|
|
+ testname3: <test-description-line>
|
||
|
|
+ <test-description-line>
|
||
|
|
+ <test-description-line>
|
||
|
|
+ ...
|
||
|
|
+ output: <expected-output-string>
|
||
|
|
+
|
||
|
|
+ # 'testname3' will be run and compared two times, for both
|
||
|
|
+ # GLIBC_TUNABLES=<glibc-tunable-string1> and
|
||
|
|
+ # GLIBC_TUNABLES=<glibc-tunable-string2>. This can be cleared and reset by the
|
||
|
|
+ # 'clear_tunables' command:
|
||
|
|
+ clear_tunables
|
||
|
|
+
|
||
|
|
+ # Multiple expected outputs can also be specified, with an associated
|
||
|
|
+ # tunable option in (), which multiple tests will be run with each
|
||
|
|
+ # GLIBC_TUNABLES=... option tried.
|
||
|
|
+ testname4:
|
||
|
|
+ <test-description-line>
|
||
|
|
+ ...
|
||
|
|
+ output(<glibc-tunable-string1>): <expected-output-string-1>
|
||
|
|
+ output(<glibc-tunable-string2>): <expected-output-string-2>
|
||
|
|
+ # Individual tunable output cases can be XFAILed, though note that
|
||
|
|
+ # this will have the effect of XFAILing the entire 'testname4' test
|
||
|
|
+ # in the final top-level tests.sum summary.
|
||
|
|
+ xfail_output(<glibc-tunable-string3>): <expected-output-string-3>
|
||
|
|
+
|
||
|
|
+ # When multiple outputs (with specific tunable strings) are specified,
|
||
|
|
+ # these take priority over any active 'tunable_option' settings.
|
||
|
|
+
|
||
|
|
+ # When a test is meant to be placed under 'xtests' (not run under
|
||
|
|
+ # "make check", but only when "make xtests" is used), the testcase name can be
|
||
|
|
+ # declared using 'xtest(<test-name>)':
|
||
|
|
+ ...
|
||
|
|
+ xtest(test-too-big1): <test-description>
|
||
|
|
+ output: <expected-output-string>
|
||
|
|
+ ...
|
||
|
|
+
|
||
|
|
+ # Do note that under current elf/Makefile organization, for such a xtest case,
|
||
|
|
+ # while the test execution is only run under 'make xtests', the associated
|
||
|
|
+ # DSOs are always built even under 'make check'.
|
||
|
|
+
|
||
|
|
+On the description language used, an example description line string:
|
||
|
|
+
|
||
|
|
+ a->b!->[cdef];c=>g=>h;{+c;%c;-c}->a
|
||
|
|
+
|
||
|
|
+Each identifier represents a shared object module, currently sequences of
|
||
|
|
+letters/digits are allowed, case-sensitive.
|
||
|
|
+
|
||
|
|
+All such shared objects have a constructor/destructor generated for them
|
||
|
|
+that emits its name followed by a '>' for constructors, and '<' followed by
|
||
|
|
+its name for destructors, e.g. if the name is 'obj1', then "obj1>" and "<obj1"
|
||
|
|
+is printed by its constructor/destructor respectively.
|
||
|
|
+
|
||
|
|
+The -> operator specifies a link time dependency, these can be chained for
|
||
|
|
+convenience (e.g. a->b->c->d).
|
||
|
|
+
|
||
|
|
+The => operator creates a call-reference, e.g. for a=>b, an fn_a() function
|
||
|
|
+is created inside module 'a', which calls fn_b() in module 'b'.
|
||
|
|
+These module functions emit 'name()' output in nested form,
|
||
|
|
+e.g. a=>b emits 'a(b())'
|
||
|
|
+
|
||
|
|
+For single character object names, square brackets [] in the description
|
||
|
|
+allows specifying multiple objects; e.g. a->[bcd]->e is equivalent to
|
||
|
|
+ a->b->e;a->c->e;a->d->e
|
||
|
|
+
|
||
|
|
+The () parenthesis construct with space separated names is also allowed for
|
||
|
|
+specifying objects. For names with integer suffixes a range can also be used,
|
||
|
|
+e.g. (foo1 bar2-5), specifies DSOs foo1, bar2, bar2, bar3, bar4, bar5.
|
||
|
|
+
|
||
|
|
+A {} construct specifies the main test program, and its link dependencies
|
||
|
|
+are also specified using ->. Inside {}, a few ;-separated constructs are
|
||
|
|
+allowed:
|
||
|
|
+ +a Loads module a using dlopen(RTLD_LAZY|RTLD_GLOBAL)
|
||
|
|
+ ^a Loads module a using dlopen(RTLD_LAZY)
|
||
|
|
+ %a Use dlsym() to load and call fn_a()
|
||
|
|
+ @a Calls fn_a() directly.
|
||
|
|
+ -a Unloads module a using dlclose()
|
||
|
|
+
|
||
|
|
+The generated main program outputs '{' '}' with all output from above
|
||
|
|
+constructs in between. The other output before/after {} are the ordered
|
||
|
|
+constructor/destructor output.
|
||
|
|
+
|
||
|
|
+If no {} construct is present, a default empty main program is linked
|
||
|
|
+against all objects which have no dependency linked to it. e.g. for
|
||
|
|
+'[ab]->c;d->e', the default main program is equivalent to '{}->[abd]'
|
||
|
|
+
|
||
|
|
+Sometimes for very complex or large testcases, besides specifying a
|
||
|
|
+few explicit dependencies from main{}, the above default dependency
|
||
|
|
+behavior is still useful to automatically have, but is turned off
|
||
|
|
+upon specifying a single explicit {}->dso_name.
|
||
|
|
+In this case, add {}->* to explicitly add this generation behavior:
|
||
|
|
+
|
||
|
|
+ # Main program links to 'foo', and all other objects which have no
|
||
|
|
+ # dependency linked to it.
|
||
|
|
+ {}->foo,{}->*
|
||
|
|
+
|
||
|
|
+Note that '*' works not only on main{}, but can be used as the
|
||
|
|
+dependency target of any object. Note that it only works as a target,
|
||
|
|
+not a dependency source.
|
||
|
|
+
|
||
|
|
+The '!' operator after object names turns on permutation of its
|
||
|
|
+dependencies, e.g. while a->[bcd] only generates one set of objects,
|
||
|
|
+with 'a.so' built with a link line of "b.so c.so d.so", for a!->[bcd]
|
||
|
|
+permutations of a's dependencies creates multiple testcases with
|
||
|
|
+different link line orders: "b.so c.so d.so", "c.so b.so d.so",
|
||
|
|
+"b.so d.so c.so", etc. Note that for a <test-name> specified on
|
||
|
|
+the script command-line, multiple <test-name_1>, <test-name_2>, etc.
|
||
|
|
+tests will be generated (e.g. for a!->[bc]!->[de], eight tests with
|
||
|
|
+different link orders for a, b, and c will be generated)
|
||
|
|
+
|
||
|
|
+It is possible to specify the ELF soname field for an object or the
|
||
|
|
+main program:
|
||
|
|
+ # DSO 'a' will be linked with the appropriate -Wl,-soname=x setting
|
||
|
|
+ a->b->c;soname(a)=x
|
||
|
|
+ # The the main program can also have a soname specified
|
||
|
|
+ soname({})=y
|
||
|
|
+
|
||
|
|
+This can be used to test how ld.so behaves when objects and/or the
|
||
|
|
+main program have such a field set.
|
||
|
|
+
|
||
|
|
+
|
||
|
|
+Strings Output by Generated Testcase Programs
|
||
|
|
+
|
||
|
|
+The text output produced by a generated testcase consists of three main
|
||
|
|
+parts:
|
||
|
|
+ 1. The constructors' output
|
||
|
|
+ 2. Output from the main program
|
||
|
|
+ 3. Destructors' output
|
||
|
|
+
|
||
|
|
+To see by example, a simple test description "a->b->c" generates a testcase
|
||
|
|
+that when run, outputs: "c>b>a>{}<a<b<c"
|
||
|
|
+
|
||
|
|
+Each generated DSO constructor prints its name followed by a '>' character,
|
||
|
|
+and the "c>b>a" part above is the full constructor output by all DSOs, the
|
||
|
|
+order indicating that DSO 'c', which does not depend on any other DSO, has
|
||
|
|
+its constructor run first, followed by 'b' and then 'a'.
|
||
|
|
+
|
||
|
|
+Destructor output for each DSO is a '<' character followed by its name,
|
||
|
|
+reflecting its reverse nature of constructors. In the above example, the
|
||
|
|
+destructor output part is "<a<b<c".
|
||
|
|
+
|
||
|
|
+The middle "{}" part is the main program. In this simple example, nothing
|
||
|
|
+was specified for the main program, so by default it is implicitly linked
|
||
|
|
+to the DSO 'a' (with no other DSOs depending on it) and only prints the
|
||
|
|
+brackets {} with no actions inside.
|
||
|
|
+
|
||
|
|
+To see an example with actions inside the main program, lets see an example
|
||
|
|
+description: c->g=>h;{+c;%c;-c}->a->h
|
||
|
|
+
|
||
|
|
+This produces a testcase, that when executed outputs:
|
||
|
|
+ h>a>{+c[g>c>];%c();-c[<c<g];}<a<h
|
||
|
|
+
|
||
|
|
+The constructor and destructor parts display the a->h dependency as expected.
|
||
|
|
+Inside the main program, the "+c" action triggers a dlopen() of DSO 'c',
|
||
|
|
+causing another chain of constructors "g>c>" to be triggered. Here it is
|
||
|
|
+displayed inside [] brackets for each dlopen call. The same is done for "-c",
|
||
|
|
+a dlclose() of 'c'.
|
||
|
|
+
|
||
|
|
+The "%c" output is due to calling to fn_c() inside DSO 'c', this comprises
|
||
|
|
+of two parts: the '%' character is printed by the caller, here it is the main
|
||
|
|
+program. The 'c' character is printed from inside fn_c(). The '%' character
|
||
|
|
+indicates that this is called by a dlsym() of "fn_c". A '@' character would
|
||
|
|
+mean a direct call (with a symbol reference). These can all be controlled
|
||
|
|
+by the main test program constructs documented earlier.
|
||
|
|
+
|
||
|
|
+The output strings described here is the exact same form placed in
|
||
|
|
+test description files' "output: <expected output>" line.
