# Makefile for support library, used only at build and test time
Update copyright dates with scripts/update-copyrights I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 6694 files FOO. I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: *** pre-commit check failed ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master

support_isolate_in_subprocess \
support: Add support_process_state_wait It allows parent process to wait for child state using a polling strategy over procfs on Linux. The polling is used over ptrace to avoid the need to handle signals on the target pid and to handle some system specific limitation (such as YAMA). The polling has some limitations, such as resource consumption due the procfs read in a loop and the lack of synchronization after the state is obtained. The interface idea is to simplify some sleep synchronization waitid tests and is to reduce timeouts by replacing arbitrary waits.

support_process_state \
Add UNSUPPORTED check in elf/tst-pldd. The testcase forks a child process and runs pldd with PID of this child. On systems where /proc/sys/kernel/yama/ptrace_scope differs from zero, pldd will fail with /usr/bin/pldd: cannot attach to process 3: Operation not permitted This patch checks if ptrace_scope exists, is zero "classic ptrace permissions" or one "restricted ptrace". If ptrace_scope exists and has a higher restriction, then the test is marked as UNSUPPORTED. The case "restricted ptrace" is handled by rearranging the processes involved during the test. Now we have the following process tree: -parent: do_test (performs output checks) --subprocess 1: pldd_process (becomes pldd via execve) ---subprocess 2: target_process (ptraced via pldd) ChangeLog: * elf/tst-pldd.c (do_test): Add UNSUPPORTED check. Rearrange subprocesses. (pldd_process): New function. * support/Makefile (libsupport-routines): Add support_ptrace. * support/xptrace.h: New file. * support/support_ptrace.c: Likewise.

support_ptrace \
[BZ 1190] Make EOF sticky in stdio. C99 specifies that the EOF condition on a file is "sticky": once EOF has been encountered, all subsequent reads should continue to return EOF until the file is closed or something clears the "end-of-file indicator" (e.g. fseek, clearerr). This is arguably a change from C89, where the wording was ambiguous; the BSDs always had sticky EOF, but the System V lineage would attempt to read from the underlying fd again. GNU libc has followed System V for as long as we've been using libio, but nowadays C99 conformance and BSD compatibility are more important than System V compatibility. You might wonder if changing the _underflow impls is sufficient to apply the C99 semantics to all of the many stdio functions that perform input. It should be enough to cover all paths to _IO_SYSREAD, and the only other functions that call _IO_SYSREAD are the _seekoff impls, which is OK because seeking clears EOF, and the _xsgetn impls, which, as far as I can tell, are unused within glibc. The test programs in this patch use a pseudoterminal to set up the necessary conditions. To facilitate this I added a new test-support function that sets up a pair of pty file descriptors for you; it's almost the same as BSD openpty, the only differences are that it allocates the optionally-returned tty pathname with malloc, and that it crashes if anything goes wrong. [BZ #1190] [BZ #19476] * libio/fileops.c (_IO_new_file_underflow): Return EOF immediately if the _IO_EOF_SEEN bit is already set; update commentary. * libio/oldfileops.c (_IO_old_file_underflow): Likewise. * libio/wfileops.c (_IO_wfile_underflow): Likewise. * support/support_openpty.c, support/tty.h: New files. * support/Makefile (libsupport-routines): Add support_openpty. * libio/tst-fgetc-after-eof.c, wcsmbs/test-fgetwc-after-eof.c: New test cases. * libio/Makefile (tests): Add tst-fgetc-after-eof. * wcsmbs/Makefile (tests): Add tst-fgetwc-after-eof.

support: Add support_process_state_wait It allows parent process to wait for child state using a polling strategy over procfs on Linux. The polling is used over ptrace to avoid the need to handle signals on the target pid and to handle some system specific limitation (such as YAMA). The polling has some limitations, such as resource consumption due the procfs read in a loop and the lack of synchronization after the state is obtained. The interface idea is to simplify some sleep synchronization waitid tests and is to reduce timeouts by replacing arbitrary waits.

Fix alignment of TLS variables for tls variant TLS_TCB_AT_TP [BZ #23403] The alignment of TLS variables is wrong if accessed from within a thread for architectures with tls variant TLS_TCB_AT_TP. For the main thread the static tls data is properly aligned. For other threads the alignment depends on the alignment of the thread pointer as the static tls data is located relative to this pointer. This patch adds this alignment for TLS_TCB_AT_TP variants in the same way as it is already done for TLS_DTV_AT_TP. The thread pointer is also already properly aligned if the user provides its own stack for the new thread. This patch extends the testcase nptl/tst-tls1.c in order to check the alignment of the tls variables and it adds a pthread_create invocation with a user provided stack. The test itself is migrated from test-skeleton.c to test-driver.c and the missing support functions xpthread_attr_setstack and xposix_memalign are added. ChangeLog: [BZ #23403] * nptl/allocatestack.c (allocate_stack): Align pointer pd for TLS_TCB_AT_TP tls variant. * nptl/tst-tls1.c: Migrate to support/test-driver.c.

Bug 20116: Fix use after free in pthread_create() The commit documents the ownership rules around 'struct pthread' and when a thread can read or write to the descriptor. With those ownership rules in place it becomes obvious that pd->stopped_start should not be touched in several of the paths during thread startup, particularly so for detached threads. In the case of detached threads, between the time the thread is created by the OS kernel and the creating thread checks pd->stopped_start, the detached thread might have already exited and the memory for pd unmapped. As a regression test we add a simple test which exercises this exact case by quickly creating detached threads with large enough stacks to ensure the thread stack cache is bypassed and the stacks are unmapped. Before the fix the testcase segfaults, after the fix it works correctly and completes without issue. For a detailed discussion see: https://www.sourceware.org/ml/libc-alpha/2017-01/msg00505.html

nptl: Invert the mmap/mprotect logic on allocated stacks (BZ#18988) Current allocate_stack logic for create stacks is to first mmap all the required memory with the desirable memory and then mprotect the guard area with PROT_NONE if required. Although it works as expected, it pessimizes the allocation because it requires the kernel to actually increase commit charge (it counts against the available physical/swap memory available for the system). The only issue is to actually check this change since side-effects are really Linux specific and to actually account them it would require a kernel specific tests to parse the system wide information. On the kernel I checked /proc/self/statm does not show any meaningful difference for vmm and/or rss before and after thread creation. I could only see really meaningful information checking on system wide /proc/meminfo between thread creation: MemFree, MemAvailable, and Committed_AS shows large difference without the patch. I think trying to use these kind of information on a testcase is fragile. The BZ#18988 reports shows that the commit pages are easily seen with mlockall (MCL_FUTURE) (with lock all pages that become mapped in the process) however a more straighfoward testcase shows that pthread_create could be faster using this patch: -- static const int inner_count = 256; static const int outer_count = 128; static void *thread1(void *arg) { return NULL; } static void *sleeper(void *arg) { pthread_t ts[inner_count]; for (int i = 0; i < inner_count; i++) pthread_create (&ts[i], &a, thread1, NULL); for (int i = 0; i < inner_count; i++) pthread_join (ts[i], NULL); return NULL; } int main(void) { pthread_attr_init(&a); pthread_attr_setguardsize(&a, 1<<20); pthread_attr_setstacksize(&a, 1134592); pthread_t ts[outer_count]; for (int i = 0; i < outer_count; i++) pthread_create(&ts[i], &a, sleeper, NULL); for (int i = 0; i < outer_count; i++) pthread_join(ts[i], NULL); assert(r == 0); } return 0; } -- On x86_64 (4.4.0-45-generic, gcc 5.4.0) running the small benchtests I see: $ time ./test real 0m3.647s user 0m0.080s sys 0m11.836s While with the patch I see: $ time ./test real 0m0.696s user 0m0.040s sys 0m1.152s So I added a pthread_create benchtest (thread_create) which check the thread creation latency. As for the simple benchtests, I saw improvements in thread creation on all architectures I tested the change. Checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu, arm-linux-gnueabihf, powerpc64le-linux-gnu, sparc64-linux-gnu, and sparcv9-linux-gnu.

Linux: Implement interfaces for memory protection keys This adds system call wrappers for pkey_alloc, pkey_free, pkey_mprotect, and x86-64 implementations of pkey_get and pkey_set, which abstract over the PKRU CPU register and hide the actual number of memory protection keys supported by the CPU. pkey_mprotect with a -1 key is implemented using mprotect, so it will work even if the kernel does not support the pkey_mprotect system call. The system call wrapers use unsigned int instead of unsigned long for parameters, so that no special treatment for x32 is needed. The flags argument is currently unused, and the access rights bit mask is limited to two bits by the current PKRU register layout anyway.

nptl: Fix pthread_rwlock_try*lock stalls (Bug 23844) For a full analysis of both the pthread_rwlock_tryrdlock() stall and the pthread_rwlock_trywrlock() stall see: https://sourceware.org/bugzilla/show_bug.cgi?id=23844#c14 In the pthread_rwlock_trydlock() function we fail to inspect for PTHREAD_RWLOCK_FUTEX_USED in __wrphase_futex and wake the waiting readers. In the pthread_rwlock_trywrlock() function we write 1 to __wrphase_futex and loose the setting of the PTHREAD_RWLOCK_FUTEX_USED bit, again failing to wake waiting readers during unlock. The fix in the case of pthread_rwlock_trydlock() is to check for PTHREAD_RWLOCK_FUTEX_USED and wake the readers. The fix in the case of pthread_rwlock_trywrlock() is to only write 1 to __wrphase_futex if we installed the write phase, since all other readers would be spinning waiting for this step. We add two new tests, one exercises the stall for pthread_rwlock_trywrlock() which is easy to exercise, and one exercises the stall for pthread_rwlock_trydlock() which is harder to exercise. The pthread_rwlock_trywrlock() test fails consistently without the fix, and passes after. The pthread_rwlock_tryrdlock() test fails roughly 5-10% of the time without the fix, and passes all the time after.

Linux: Implement interfaces for memory protection keys This adds system call wrappers for pkey_alloc, pkey_free, pkey_mprotect, and x86-64 implementations of pkey_get and pkey_set, which abstract over the PKRU CPU register and hide the actual number of memory protection keys supported by the CPU. pkey_mprotect with a -1 key is implemented using mprotect, so it will work even if the kernel does not support the pkey_mprotect system call. The system call wrapers use unsigned int instead of unsigned long for parameters, so that no special treatment for x32 is needed. The flags argument is currently unused, and the access rights bit mask is limited to two bits by the current PKRU register layout anyway.

Adjust name of ld.so in test-container.c. The test-container.c file assumes that ld.so is always named something like /elf/ld-linux-*. But e.g. on s390x it is named ld64.so.1 or ld.so.1 on s390. There are other architectures like power or mips with similar names. This patch introduces the new global variable support_objdir_elf_ldso which contains the absolute path to the runtime linker used by the testsuite, e.g. OBJDIR_PATH/elf/ld-linux-x86-64.so.2. The check in test-container.c is now comparing against this path. Without this patch, test-container.c is searching invalid files / directories and fails to find glibc/nss/tst-nss-test3.root/tst-nss-test3.script. Then the test tst-nss-test3 fails!

localedef: Add verbose messages for failure paths. During testing of localedef running in a minimal container there were several error cases which were hard to diagnose since they appeared as strerror (errno) values printed by the higher level functions. This change adds three new verbose messages for potential failure paths. The new messages give the user the opportunity to use -v and display additional information about why localedef might be failing. I found these messages useful myself while writing a localedef container test for --no-hard-links. Since the changes cleanup the code that handle codeset normalization we add tst-localedef-path-norm which contains many sub-tests to verify the correct expected normalization of codeset strings both when installing to default paths (the only time normalization is enabled) and installing to absolute paths. During the refactoring I created at least one buffer-overflow which valgrind caught, but these tests did not catch because the exec in the container had a very clean heap with zero-initialized memory. However, between valgrind and the tests the results are clean. The new tst-localedef-path-norm passes without regression on x86_64. Change-Id: I28b9f680711ff00252a2cb15625b774cc58ecb9d

Correct timespec implementation [BZ #26232] commit 04deeaa9ea74b0679dfc9d9155a37b6425f19a9f Author: Lucas A. M. Magalhaes <lamm@linux.ibm.com> Date: Fri Jul 10 19:41:06 2020 -0300 Fix time/tst-cpuclock1 intermitent failures has 2 issues: 1. It assumes time_t == long which is false on x32. 2. tst-timespec.c is compiled without -fexcess-precision=standard which generates incorrect results on i686 in support_timespec_check_in_range: double ratio = (double)observed_norm / expected_norm; return (lower_bound <= ratio && ratio <= upper_bound); This patch does 1. Compile tst-timespec.c with -fexcess-precision=standard. 2. Replace long with time_t. 3. Replace LONG_MIN and LONG_MAX with TYPE_MINIMUM (time_t) and TYPE_MAXIMUM (time_t).

support: Add support_process_state_wait It allows parent process to wait for child state using a polling strategy over procfs on Linux. The polling is used over ptrace to avoid the need to handle signals on the target pid and to handle some system specific limitation (such as YAMA). The polling has some limitations, such as resource consumption due the procfs read in a loop and the lack of synchronization after the state is obtained. The interface idea is to simplify some sleep synchronization waitid tests and is to reduce timeouts by replacing arbitrary waits.

The CNAME and PTR record contents was extracted from the wrong buffer (whole packet instead RDATA). This desynced the parsing after the first CNAME or PTR record. Also fix the AAAA record parsing by checking their sizes.

support: Add support_capture_subprogram Its API is similar to support_capture_subprocess, but rather creates a new process based on the input path and arguments. Under the hoods it uses posix_spawn to create the new process. It also allows the use of other support_capture_* functions to check for expected results and free the resources. Checked on x86_64-linux-gnu. * support/Makefile (libsupport-routines): Add support_subprocess, xposix_spawn, xposix_spawn_file_actions_addclose, and xposix_spawn_file_actions_adddup2. (tst-support_capture_subprocess-ARGS): New rule. * support/capture_subprocess.h (support_capture_subprogram): New prototype. * support/support_capture_subprocess.c (support_capture_subprocess): Refactor to use support_subprocess and support_capture_poll. (support_capture_subprogram): New function. * support/tst-support_capture_subprocess.c (write_mode_to_str, str_to_write_mode, test_common, parse_int, handle_restart, do_subprocess, do_subprogram, do_multiple_tests): New functions. (do_test): Add support_capture_subprogram tests. * support/subprocess.h: New file. * support/support_subprocess.c: Likewise. * support/xposix_spawn.c: Likewise. * support/xposix_spawn_file_actions_addclose.c: Likewise. * support/xposix_spawn_file_actions_adddup2.c: Likewise. * support/xspawn.h: Likewise.

support: Introduce new subdirectory for test infrastructure The new test driver in <support/test-driver.c> has feature parity with the old one. The main difference is that its hooking mechanism is based on functions and function pointers instead of macros. This commit also implements a new environment variable, TEST_COREDUMPS, which disables the code which disables coredumps (that is, it enables them if the invocation environment has not disabled them). <test-skeleton.c> defines wrapper functions so that it is possible to use existing macros with the new-style hook functionality. This commit changes only a few test cases to the new test driver, to make sure that it works as expected.
