Ryan El KochtaandgVisor bot bc65dcecb2 Allow TFD_TIMER_CANCEL_ON_SET in timerfd_settime() with no effect
Needed as part of systemd compatibility. Eventually we may consider supporting
TFD_TIMER_CANCEL_ON_SET properly.

Jamie LiuandgVisor bot 19f12e64c8 Move //pkg/sentry/kernel/time to //pkg/sentry/ktime.
This avoids needing to rename it everywhere it's imported.

Etienne PerotandgVisor bot da6948a692 gVisor: Refactor SyscallFn to take in the syscall number as argument.
This will be used to plumb the syscall number through to a counter metric that
exports the number of times an unimplemented syscall has been called.

Plenty of syscall implementations call `EmitUnimplementedEvent` for flags and
settings that are not implemented. With `sysno` available, they will be able
to plumb that bit of information through.

Ayush RanjanandgVisor bot 1003ae8e93 Delete VFS1 completely.
- Delete pkg/sentry/fs/*.
- Move pkg/sentry/fs/fsutil out of VFS1 directory and remove VFS1 components.
- Remove remaining unused references to VFS1 from remaining codebase.
- Rename/refactor code to avoid even referencing VFS2, unless necessary.
- Rewrite VFS1-only tests to VFS2.

Ayush RanjanandgVisor bot d90d0743d3 Delete VFS1 syscall handlers.
Directly use VFS2 syscall handlers. No need to override VFS2 handlers.

Zach KoopmansandgVisor bot 895c2eaa09 [syserror] Update syserror to linuxerr for EACCES, EBADF, and EPERM.
Update all instances of the above errors to the faster linuxerr implementation.
With the temporary linuxerr.Equals(), no logical changes are made.

Zach KoopmansandgVisor bot cd84634cc0 [syserror] Change syserror to linuxerr for E2BIG, EADDRINUSE, and EINVAL
Remove three syserror entries duplicated in linuxerr. Because of the
linuxerr.Equals method, this is a mere change of return values from
syserror to linuxerr definitions.

Done with only these three errnos as CLs removing all grow to a significantly
large size.

Adin ScannellandgVisor bot 753da9604e Remove map from fd_map, change to fd_table.
This renames FDMap to FDTable and drops the kernel.FD type, which had an entire
package to itself and didn't serve much use (it was freely cast between types,
and served as more of an annoyance than providing any protection.)

Based on BenchmarkFDLookupAndDecRef-12, we can expect 5-10 ns per lookup
operation, and 10-15 ns per concurrent lookup operation of savings.

This also fixes two tangential usage issues with the FDMap. Namely, non-atomic
use of NewFDFrom and associated calls to Remove (that are both racy and fail to
drop the reference on the underlying file.)

Adrien Leravat 3688e6e99d Add CLOCK_BOOTTIME as a CLOCK_MONOTONIC alias
Makes CLOCK_BOOTTIME available with
* clock_gettime
* timerfd_create
* clock_gettime vDSO

CLOCK_BOOTTIME is implemented as an alias to CLOCK_MONOTONIC.
CLOCK_MONOTONIC already keeps track of time across save
and restore. This is the closest possible behavior to Linux
CLOCK_BOOTIME, as there is no concept of suspend/resume.
