/var/log/messages file wich is most likely not interesting but the
regression test can work on every specified filingsystem by passing a file
on that filingsystem to it as argument.
It tests:
- initial position
- seeking absolute position
- seeking end
- seeking negative relative position
more can be added later.
partial-segment by partial-segment. Each checkpoint should pass fsck_lfs -n
without errors; the results of fsck_lfs -p on non-checkpoints should also
pass fsck_lfs -n without errors.
currently implemented tests:
- check agreement of sleep time with real time (from system)
to be within 30ms
- check for EINTR return code on processing SIGALRM signals
- check for valid residual time if available from the interface
Tested interfaces:
- nanotime(2)
- select(2)
- poll(2)
- sleep(3)
links etc.
This currently does not test the flags -i, -f, and -v. It also does not
test removal of setuid or setgid bits if the owner can't be changed, nor
does it check creation of device nodes etc.
While touching all vptofh/fhtovp functions, get rid of VFS_MAXFIDSIZ,
version the getfh(2) syscall and explicitly pass the size available in
the filehandle from userland.
Discussed on tech-kern, with lots of help from yamt (thanks!).
particular, the caller can now choose whether to wait for the condition
to be met, and if the caller of LFCNWRAPSTOP dies or otherwise closes
the descriptor, the filesystem is started again. Updated the ckckp
regression test to use the new semantics.
dump_lfs(8) now uses the fcntls to implement LFS-style snapshotting through
the -X flag, addressing PR#33457 albeit not using fss(4). Fixed a couple
other problems with dump_lfs that manifested themselves during testing.
The former two are no longer necessary as slstats is no more
and pppstats now uses an ioctl instead of rummaging through kmem.
The latter has nothign interesting for the userland, but uses
struct bintime that I'm about to hide under #ifdef _KERNEL.
A bunch of remaining <net/if_*.h> headers is pretty useless to the
userland too, but ... someone else's yag to shave...
