| |
Good day all, I recently found that the linux kernel does not support setting a process' RLIMIT_NOFILE limits to the #define RLIM_INFINITY. My patch will add such support by setting the limit to the maximum supported by the kernel when a call to set a limit to RLIM_INFINITY is made.
I understand that the semantics do not match exactly but all kernels are limited by real hard limits and/or available memory, I think that it is therefore acceptable to have a call to set a limit to RLIM_INFINITY actually set the limit to the maximum extent supported by the kernel.
