README
libsydtime is a
LD_PRELOAD library
to replace vDSO time calls with system calls.
This library is meant as a complement to syd's
trace/deny_tsc sandbox command.
To install from source, clone the repository at https://git.sr.ht/~alip/syd, change
into the directory time and run make, make test and doas make install. The
only prerequisite is Rust 1.56.1 or later.
Below is a simple example of how to use libsydtime with syd:
$ strace -qf -e%clock syd -ppaludis -mtrace/deny_tsc:1 -eLD_PRELOAD=/usr/local/lib/libsydtime.so date
[pid 27095] clock_gettime(CLOCK_REALTIME, {tv_sec=1706186439, tv_nsec=28829866}) = 0
Thu Jan 25 12:40:39 UTC 2024
[pid 27095] +++ exited with 0 +++
$ strace -qf -e%clock syd -ppaludis date # vDSO
Thu Jan 25 12:41:25 UTC 2024
[pid 27103] +++ exited with 0 +++
$ strace -qf -e%clock syd -ppaludis -mtrace/deny_tsc:1 date # vDSO not permitted
[pid 27113] --- SIGSEGV {si_signo=SIGSEGV, si_code=SI_KERNEL, si_addr=NULL} ---
[pid 27113] +++ killed by SIGSEGV +++
