WebJan 19, 2024 · A thread local variable is a variable that will have a unique instance per thread. Each time a new thread is created, the space required to store the thread local variables is allocated. TLS variables are stored in dynamic TLS sections. TLS Sections In the previous article we saw how variables were stored in the .data and .bss sections. WebJun 1, 2024 · [email protected]. State. Superseded. Headers. show. Return-Path:
WebFeb 5, 2024 · * The library contains thread-local storage. * A thread runs, and then proceeds to touch the thread-local storage, eventually invoking tls_get_addr_tail () (in /elf/dl-tls.c) and then allocate_and_init () and then __libc_memalign (). * Eventually, this storage is deallocated using free () instead __libc_free (). WebThe GLib threading system used to be initialized with g_thread_init(). This is no longer necessary. Since version 2.32, the GLib threading system is automatically initialized at …
WebThe __rseq_abi TLS and glibc-2.35's ABI for per-thread data cannot actively coexist in a process, because the kernel supports only a single rseq registration per thread. Here is the scheme introduced to ensure selftests can work both with an older glibc and with glibc-2.35+: - librseq exposes its own "rseq_offset, rseq_size, rseq_flags" ABI. WebMay 3, 2013 · Linking with certain external libraries can inflate the required amount of thread local storage to astronomical proportions. When the Rust runtime tries to create its threads, it requests a stack size independent of the TLS size, which can lead to pthread_create() failing with EINVAL when the stack size is smaller than the TLS size.

It introduces a user-space ABI based on the thread pointer to access a reserved area of the TCB. The rseq selftests originally expected the rseq thread data to sit in a __rseq_abi TLS variable.
WebThe default stack size for new threads on glibc is determined based on the resource limit governing the main thread’s stack ( RLIMIT_STACK ).
