This patch is against Cray patch against openssh-SNAP-20010710. Here a few notes about them: 1) rijndael does not work on cray due to the fact it is rooted in 32 bits. I looking for a fix, it may come form Wendy Palam. For now the cray default to the following cihpers for ssh version 2 ssh are: 3des-cbc,blowfish-cbc,cast128-cbc,arcfour 2) Crays don't have setitimer so I

HP-UX 11 is looping on SIGCHLD/sigchld_handler2() when exiting a protocol 2 session apparently because we don't call wait before reinstalling the handler. Any thoughts on this issue or how to address it? serverloop.c from latest snapshots: void sigchld_handler2(int sig) { int save_errno = errno; debug("Received SIGCHLD."); child_terminated = 1; signal(SIGCHLD,

This should not be a

We use ssh (RedHat 2.5.2p2-5) heavily in non-interactive mode, for managing servers from central controllers, and transferring applications/ data around networks. Very occasionally we've seen the situation where the ssh client and server are both stuck in select, both selecting on only the tcp socket of the connection, and with no timeout. No children of sshd remain (even as zombies), and it

Hi What if you have sysv signals (i.e. signal is restored when handler is called) and child process exits here? Zombie will be left, because SIGCHLD is ignored at that point. Shouldn't signal be before waitpid? Mikulas static void main_sigchld_handler(int sig) { int save_errno = errno; pid_t pid; int status; while ((pid = waitpid(-1, &status, WNOHANG))

Peter Dimitrov and myself were debugging a very peculiar bug when libguestfs is run as a plugin from collectd: https://www.redhat.com/archives/libguestfs/2018-November/thread.html#00023 The long story short is that collectd leaks SIGCHLD == SIG_IGN setting into plugins: https://www.redhat.com/archives/libguestfs/2018-November/msg00095.html This means that any plugin that does the usual

So, we just found some ugly behaviour of OpenSSH on Solaris. Sometimes, it seems, sshd gets started with SIGCHLD blocked, this, apparently, being the setting of sshd's parent (a shell no doubt); signal blocking is inherited across exec*(). I don't know exactly which shell, or what really is at fault, but it happens. The problem is that the code in collect_children() first blocks SIGCHLD

Hello, I'm using an rsync server on a Linux packages repository (deb packages) to sync all mirrors. The mirrors sync every 10 minutes. Most of the time, there is nothing to sync, except a timestamp file, so the sync is pretty fast. Anyway, after it has been working well for some time (between 2 and 24hours), the rsync daemon crashes. It is still running but seems to retry something

Thank you Tzafrir. I had been using different users in earlier attempts to make this work. Decided to try everything where root is the only user, simply to verify it's working. For problem 2, where asterisk is writing to the log but doesn't seem to receive the SIP packets even though tcpdump indicates they are making it to the box on 5060, I am starting asterisk while logged in as root.

Can anyone offer any advice on this issue? We've tried patching sshd to have a maximum 10 second timeout when calling select() in serverloop.c, and this doesn't appear to have had any ill effects.
