| | | | | | | | | | | | | | start_addresses in sysdeps/powerpc/powerpc64/start.S is historical baggage that should disappear. Until someone does that, relocating stinfo->main by hand is one solution to the fact that the field may be unrelocated at the time it is accessed. This is similar to what is done for dynamic tags via the D_PTR macro. stinfo->init and stinfo->fini are zero in both powerpc64/start.S and powerpc32/start.S, so make it a little more obvious they are unused by passing NULLs to LIBC_START_MAIN.

* hppa: Revise gettext trampoline designJohn David Anglin2022-02-223-31/+35
| | | | | | | | | | | | | | | | | | | The current getcontext return trampoline is overly complex and it unnecessarily clobbers several registers. By saving the context pointer (r26) in the context, __getcontext_ret can restore any registers not restored by setcontext. This allows getcontext to save and restore the entire register context present when getcontext is entered. We use the unused oR0 context slot for the return from __getcontext_ret. While this is not directly useful in C, it can be exploited in assembly code. Registers r20, r23, r24 and r25 are not clobbered in the call path to getcontext. This allows a small simplification of swapcontext. It also allows saving and restoring the 6-bit SAR register in the LSB of the oSAR context slot. The getcontext flag value can be stored in the MSB of the oSAR slot.

* hppa: Fix swapcontextJohn David Anglin2022-02-183-7/+58
| | | | | | | | | | | | | | | | | This change fixes the failure of stdlib/tst-setcontext2 and stdlib/tst-setcontext7 on hppa. The implementation of swapcontext in C is broken. C saves the return pointer (rp) and any non call-clobbered registers (in this case r3, r4 and r5) on the stack. However, the setcontext call in swapcontext pops the stack and subsequent calls clobber the saved registers. When the context in oucp is restored, both tests fault. Here we rewrite swapcontext in assembly code to avoid using the stack for register values that need to be used after restoration. The getcontext and setcontext routines are revised to save and restore register ret1 for normal returns. We copy the oucp pointer to ret1. This allows access to the old context after calling getcontext and setcontext.

* posix: Add terminal control setting support for posix_spawnAdhemerval Zanella2022-01-2534-0/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently there is no proper way to set the controlling terminal through posix_spawn in race free manner [1]. This forces shell implementations to keep using fork+exec when launching background process groups, even when using posix_spawn yields better performance. This patch adds a new GNU extension so the creating process can configure the created process terminal group. This is done with a new flag, POSIX_SPAWN_TCSETPGROUP, along with two new attribute functions: posix_spawnattr_tcsetpgrp_np, and posix_spawnattr_tcgetpgrp_np. The function sets a new attribute, spawn-tcgroupfd, that references to the controlling terminal. The controlling terminal is set after the spawn-pgroup attribute, and uses the spawn-tcgroupfd along with current creating process group (so it is composable with POSIX_SPAWN_SETPGROUP). To create a process and set the controlling terminal, one can use the following sequence: posix_spawnattr_t attr; posix_spawnattr_init (&attr); posix_spawnattr_setflags (&attr, POSIX_SPAWN_TCSETPGROUP); posix_spawnattr_tcsetpgrp_np (&attr, tcfd); If the idea is also to create a new process groups: posix_spawnattr_t attr; posix_spawnattr_init (&attr); posix_spawnattr_setflags (&attr, POSIX_SPAWN_TCSETPGROUP | POSIX_SPAWN_SETPGROUP); posix_spawnattr_tcsetpgrp_np (&attr, tcfd); posix_spawnattr_setpgroup (&attr, 0); The controlling terminal file descriptor is ignored if the new flag is not set. This interface is slight different than the one provided by QNX [2], which only provides the POSIX_SPAWN_TCSETPGROUP flag. The QNX documentation does not specify how the controlling terminal is obtained nor how it iteracts with POSIX_SPAWN_SETPGROUP. Since a glibc implementation is library based, it is more straightforward and avoid requires additional file descriptor operations to request the caller to setup the controlling terminal file descriptor (and it also allows a bit less error handling by posix_spawn).
