With a full implementation of pthread_self in libc.so, pthread_thread_number_np is completely usable without libpthread. 2017-12-14 Florian Weimer nptl: Add pthread_thread_number_np function. * csu/libc-tls.c (__libc_setup_tls): Call __dl_inittcb. * elf/Makefile (dl-routines): Add dl-inittcb. * elf/dl-inittcb.c: New file. * elf/rtld.c (init_tls): Call __dl_inittcb. * manual/threads.texi (Non-POSIX Extensions): Reference Non-POSIX Extensions. (Non-POSIX Extensions): New node. * nptl/Makefile (routines): Add thread_number. (tests): Add tst-thread_number-single, tst-thread_number-multi, tst-thread_number-single-static, tst-thread_number-multi-static. (tests-nolibpthread): Add tst-thread_number-single, tst-thread_number-single-static. (tests-static): Add tst-thread_number-single-static, tst-thread_number-multi-static. * nptl/Versions (GLIBC_2.27): Export pthread_thread_number_np. * nptl/allocatestack.c (allocate_stack): Increment global_thread_number under__default_pthread_attr_lock and use its value to set the new thread number. * nptl/descr.h (struct pthread): Add number member. * nptl/thread_number.c: New file. * nptl/tst-thread_number-multi.c: Likewise. * nptl/tst-thread_number-single.c: Likewise. * nptl/tst-thread_number-multi-static.c: Likewise. * nptl/tst-thread_number-single-static.c: Likewise. * sysdeps/nptl/pthread.h (pthread_thread_number_np): Declare. * sysdeps/unix/sysv/linux/libc**.abilist: Update. diff --git a/csu/libc-tls.c b/csu/libc-tls.c index 00138eb43a..af81cba12c 100644 --- a/csu/libc-tls.c +++ b/csu/libc-tls.c @@ -195,6 +195,7 @@ __libc_setup_tls (void) #endif if (__builtin_expect (lossage != NULL, 0)) _startup_fatal (lossage); + __dl_inittcb (); /* Update the executable's link map with enough information to make the TLS routines happy. */ diff --git a/elf/Makefile b/elf/Makefile index 8563555079..66ce2953a4 100644 --- a/elf/Makefile +++ b/elf/Makefile @@ -30,7 +30,7 @@ routines = $(all-dl-routines) dl-support dl-iteratephdr \ # profiled libraries. dl-routines = $(addprefix dl-,load lookup object reloc deps hwcaps \ runtime init fini debug misc \ - version profile tls origin scope \ + version profile tls inittcb origin scope \ execstack caller open close trampoline \ exception sort-maps) ifeq (yes,$(use-ldconfig)) diff --git a/elf/dl-inittcb.c b/elf/dl-inittcb.c new file mode 100644 index 0000000000..5a70e9775d --- /dev/null +++ b/elf/dl-inittcb.c @@ -0,0 +1,22 @@ +/* Initialize TCB contents.
