1.2.2 release notes |
|
|
|
|
|
|
|
major changes: |
|
|
|
- child restrictions lifted after fork of multithreaded parent |
|
|
|
|
|
|
|
new features: |
|
|
|
- _Fork function (POSIX-future) |
|
|
|
- reallocarray function (extension from OpenBSD, now widespread) |

- gettid function (kernel tid as supported concept) |
|
|
|
- SIGEV_THREAD_ID sigevent API (Linux extension) |
|
|
|
- tcgetwinsize and tcsetwinsize functions (POSIX-future) |
|
|
|
|
|
|
|
performance: |
|
|
|
- faster software sqrt on archs without native sqrt instruction |
|
|
|
|
|
|
|
compatibility: |
|
|
|
- realpath no longer depends on procfs availability & accuracy |
|
|
|
- time zone parser now always prefers 64-bit tables if present |
|
|
|
- crypt_blowfish now supports $2b$ prefix |
|
|
|
- res_query now reports errors via h_errno |
|
|
|
- set*id and setrlimit are now safe in vforked/cloned child |
|
|
|
- setgroups now applies to all threads |
|
|
|
- dlopen debugger notification is improved, should work with lldb |
|
|
|
- setrlimit no longer needs __synccall broadcast on linux 2.6.36+ |
|
|
|
- faccessat with AT_EACCESS no longer needs child process on linux 5.8+ |
|
|
|
|
|
|
|
bugs fixed: |
|
|
|
- buffer overflow and infinite loop errors in wcsnrtombs (CVE-2020-28928) |
|
|
|
- sem_close unmapped still-referenced semaphores |
|
|
|
- fork of process with active aio could deadlock or crash paren |
|
|
|
- pthread_cond_wait was broken with priority-inheritance mutex |
|
|
|
- getgrouplist wrongly failed when nscd reported an empty list |
|
|
|
- abort could leak modified SIGABRT disposition to fork or posix_spawn child |
|
|
|
- regression with mallocng: malloc_usable_size(0) crashed |
|
|
|
- readlink wrongly gave EINVAL on zero length dest buffer |
|
|
|
- sqrtl was severely inaccurate (not correctly rounded) on ldquad archs |
|
|
|
- assert failure wrongly flushed stdio (possible deadlock) |
|
|
|
- MUSL_LOCPATH search was broken with multiple components |
|
|
|
- missing newline in herror output |
|
|
|
- possible deadlock in pthread_exit with pshared mutex or barrier usage |
|
|
|
- pthread_mutexattr_getprotocol didn't read back protocol |
|
|
|
- v4l2 ioctl translation for pre-time64 kernels didn't work |
|
|

arch-specific bugs fixed: |
|
|
|
- x86_64 longjmp failed to handle 0 argument reliably |
|
|
|
- i386 __set_thread_area fallback for pre-2.6 kernels didn't work |
|
|
|
- missing O_LARGEFILE macro value on x86_64, x32, mips64 |
|
|
|
- unpredictable s390x breakage from failure to preserve call-saved registers |
