Hi,

Currently, the default value for RLIMIT_MEMLOCK (defined in
include/linux/resource.h) is 32 KiB, because this value is enough for
GnuPG.

However this value is not enough for gnome-keyring-daemon, which will
store both SSH and GnuPG keys, plus user passwords for various kinds of
resources. Upstream authors recommend to provide a limit of at least 256
KiB for RLIMIT_MEMLOCK for the keys to remain securely in memory.

Given the amount of memory in current machines, I think 256 KiB is still
a very reasonable value. Could you please increase the default in the
kernel?

Thanks,
