@drapl0n add a test here please

Failed test: test_fromfd(). It expects EBADF as the return value since fd was closed when ep exited.

- replaces unsafe `unwrap()` with error handeling based on Result<> - returns appropriate error code

* handle error in epoll_wait_syscall() - replaces unsafe `unwrap()` with error handeling based on Result<> - returns appropriate error code * add epoll test that accesses epoll fd after being closed

* Fix statfs guest buffer handling * handle error in epoll_wait_syscall() (#1121) * handle error in epoll_wait_syscall() - replaces unsafe `unwrap()` with error handeling based on Result<> - returns appropriate error code * add epoll test that accesses epoll fd after being closed * add make fpcast shortcut for WITH_FPCAST=1 build * Restore lind debug import helper for debug builds (#1136) * Restore lind debug import helper * Link lind debug object in dynamic builds --------- Co-authored-by: Daniel Zhao <你çzz10239@nyu.edu> * fix getcwd with NULL buffer (#1139) getcwd(NULL, 0) is valid POSIX — glibc should allocate the buffer. Our wrapper passed NULL through TRANSLATE_GUEST_POINTER_TO_HOST which produced a bad pointer, causing the syscall to fail. bash calls getcwd(0, 0) during shell init, triggering "error retrieving current directory" on startup. Allocate a buffer when buf is NULL before calling the syscall. * Change cage epoch to atomicptr (#1125) * Change optimization level from O0 to O2 (#1112) * Change optimization level from O0 to O2 * fix tests for O2 compatibility - filetest.c, filetest1000.c: fix OOB write buffer[WRITE_BUFFER_SIZE] to buffer[WRITE_BUFFER_SIZE - 1] - alarm.c, setitimer.c: add volatile to signal_counter so O2 doesn't optimize out the spin loop - wait.c: convert to asserts, remove sleep and non-deterministic output - fork_large_memory.c: remove intermediate printf, keep single final print * skip statfs test pending O2 investigation --------- Co-authored-by: Nicholas Renner <nicholassrenner@gmail.com> * Increase MAX_CAGEID to 2048 and fix alloc off-by-one (#1140) * Increase MAX_CAGEID to 2048 and fix alloc off-by-one Raise the cage ID limit from 1024 to 2048. Fix off-by-one in alloc_cage_id where the old condition (v <= MAX_CAGEID) could return a cage ID equal to MAX_CAGEID, which is out of bounds for CAGE_MAP. Add fork_max_cages test that exercises the full cage ID space. * Add fork_max_cages to skip list * Enable statfs test in CI * Trigger CI rerun --------- Co-authored-by: Daniel Zhao <你çzz10239@nyu.edu> Co-authored-by: drapl0n <87269662+drapl0n@users.noreply.github.com> Co-authored-by: Nicholas Renner <nicholassrenner@gmail.com> Co-authored-by: Nicholas Renner <nr2185@nyu.edu> Co-authored-by: Alice Wen <40227173+Yaxuan-w@users.noreply.github.com>
