espkk 42f72f8bb4 swaylock: fix clear_password_buffer 2018-10-14 07:40:33 +03:00
Drew DeVault c89e00a97e Fix swaylock w/shadow on glibc, improve security 
Today I learned that GNU flaunts the POSIX standard in yet another
creative way. Additionally, this adds some security improvements,
namely:

- Zeroing out password buffers in the privileged child process
- setuid/setgid after reading /etc/shadow

Arkadiusz Hiler eed0bc3ebd Add support for installing binaries with DT_RPATH 
It's better to use DT_RPATH dynamic section of the elf binary to store
the paths of libraries to load instead of overwriting LD_LIBRARY_PATH
for the whole environment, causing surprises. This solution is much more
transparent and perfectly suitable for running contained installations
of wayland/wlroots/sway.

The code unsetting the LD_LIBRARY_PATH/LD_PRELOAD was also deleted as
it's a placebo security at best - we should trust the execution path
that leads us to running sway, and it's way too late to care about those
variables since we already started executing our compositor, thus we
would be compromised anyway.

Drew DeVault c977349120 Add support for building swaylock without PAM 
This involves setuid'ing swaylock, which then forks and drops perms on
the parent process. The child process remains root and listens on a pipe
for requests to validate passwords against /etc/shadow.

Geoff Greer c495164f60 swaybar, swaylock, & tree/container: Set cairo font options to render text and lines with subpixel hinting (if available). 2018-09-22 11:34:21 -07:00
sghctoma 6de777a986 Add FreeBSD-specific PAM configuration 
The "login" PAM configuration means somathing entirely different on
FreeBSD than on Linux: if you try to authenticate as the calling user,
it OKs the request without prompting for password. The "passwd" config
implements the desired functionality, therefore it should be used by
swaylock.

regular clients; please use the xkb_state_mod_*_is_active API instead"
so here it is

Geoff Greer ad6aa21c43 swaylock: Securely zero-out password. 
- Replace char* with static array. Any chars > 1024 will be discarded.
- mlock() password buffer so it can't be written to swap.
- Clear password buffer after auth succeeds or fails.

This is basically the same treatment I gave the 0.15 branch in https://github.com/swaywm/sway/pull/1519
