Hi, the following patch changes the Cygwin specific function copy_environment() to not restricting the strlen of a single environment variable to 512 byte. The PAM specific function do_pam_environment() (also in session.c) has the same problem but I don't know if that's important for PAM since only PAM specific environment variables are copied in that function. The...

This was a rather longer trip around the houses than I anticipated! The basic purpose of the patch series is to set $nbdkit_stdio_safe to "0" or "1" in sh and eval plugin scripts. To do that, I ended up adding a nicer way to manipulate environ lists, and to do that, I ended up adding a whole generic vector implementation which is applicable in a lot of different places.

The $tmpdir environment variable is used by the eval and sh plugins to communicate the path to the temporary directory created by the plugin for shell scripts to use for temporary files. Previously we set this environment variable globally (in .load()), but this means the environment variable can be leaked into undesirable places, eg. into the --run script: $ nbdkit sh - --run 'echo

Hello, I am using OpenSSH-3.8p1 on HP-UX machine with USE_POSIX_THREADS option. This is for making the kerberos credentials file to be created in the system with PAM. In OpenSSH versions 3.5 when authentication is done with pam kerberos, a /tmp/krb5cc_X_Y file is created on the server side. But the KRB5CCNAME variable is not set by default. So, after we manually set this environment variable, the

...bles sent through AcceptEnv/SendEnv. Note that there is no way it could be fixed at the PAM level: PAM prepares the environment for the child not knowing the sent variables. It is openssh-server that does the things in the wrong order. What the patch does: it changes the child_set_env function in copy_environment to child_set_env_safe (basically the same as child_set_env but with a twist): any variable which has already been inserted in the environment is not clobbered by copy_environment. Since the function copy_environment is the one used to bring the PAM settings inside the environment, the PAM settings...
