Not all OSes have SA_RESTART (for instance, SunOS does not). Also, for the non-SA_RESTART case in scp.c sa.sa_flags was not being initialized (noted by dworkin at village.org). - todd --- scp.c.DIST Sat Feb 17 17:56:33 2001 +++ scp.c Sat Feb 17 17:57:59 2001 @@ -1224,8 +1224,9 @@ struct sigaction sa; sa.sa_handler = updateprogressmeter; sigemptyset((sigset_t *)&sa.sa_mask); + sa.sa_flags = 0; #...

...not set any ELF flags that the kernel could detect. Thus to fix this regression we must construct descriptors solely for passing to/from the kernel. Despite this, usr/dash/static/sh -c "usr/utils/static/true; exit" was still seen to hang during the test suite. This is because sa_mask and sa_flags were round the wrong way (matching the old sigaction syscall rather than the newer rt_sigaction syscall, despite the former not existing on ia64), causing the kernel to think SA_NOCLDWAIT was set. This bug appears to have been present since the ia64 port was first committed. --- usr/include/arch/i...

I am aware that there have been several posts related to ssh connections hanging, i have tried to read through most of them in the archives... I am posting this in hopes that it may present something new that will further help resolve this problem. The problem i am having appears to be similar to what others have reported where after typing exit in an interactive shell the connection is not

Commit 8418552 ("[klibc] ia64: Fix shared build") missed this use of the GP register, although the code appears to have been dubious anyway, assuming the address of errno was the first thing pointed to by GP. --- usr/klibc/arch/ia64/vfork.S | 6 +----- 1 file changed, 1 insertion(+), 5 deletions(-) diff --git a/usr/klibc/arch/ia64/vfork.S b/usr/klibc/arch/ia64/vfork.S index

Patch registers SIGTSTP hook where it sends reset terminal color control sequence using write and fsync. Handler is installed only if signal is not being ignored. Patch uses rl_free_line_state and rl_cleanup_after_signal to unhook readline from terminal, then it calls original TSTP handler using approach in URL below and again hooks readline using rl_reset_after_signal. Handling is based on code
