select(2) timeouts. Introduced via timecounter branch from a
tvtohz() conversion.
The left over timeout was not decremented when re-starting
the sleep in select.
on alpha (which were broken for more than a year appearently and noone
noticed). (The other archs didn't suffer because their pmap_kenter_pa()
doesn't support non-executable mappings.)
With sock_loan_thresh=4096, sb_lowat==sb_hiwat, and sowritable will never
be true (even if only a single byte is pending). Some programs (like screen)
expect select() to return that a socket is writable on a socket when there
is space to write to it. XXX: What is the right thing to do here?
EPROTONOSUPPORT instead of EAFNOSUPPORT.
from pavel@ with a little bit of clean up from myself.
XXX: netbsd32 (and perhaps other emulations) should be able
XXX: to call the standard socket calls for this i think, but
XXX: revisit this at another time.
2. implement solaris-like kmem_alloc/free api, using #1.
(note: this implementation is backed by kernel_map, thus can't be
used from interrupt context.)
the precision of getnanotime() is not suitable for file timestamps.
esp. when it's nfs-exported.
- introduce vfs_timestamp().
(the name is from freebsd. currently merely a wrapper of nanotime())
- for ufs-like filesystems, use it rather than getnanotime().
XXX check other filesystems.
so I remove the assertion uid >= 0 && uid <= UID_MAX. This squashes
a bug where Quagga would panic my machine by passing a UID outside
the range [0, UID_MAX].
AFAICT, this restores the historical (pre-kauth) behavior.
It is likely that GIDs do not satisfy the assertion gid >= 0 &&
gid <= GID_MAX, so remove that, too.
Patch from elad.
supported. This adds further differentiation between which argument to
socket(2) caused the error. No longer are invalid domain (address family)
errors classified as ENOPROTOSUPPORT errors. This should make socket(2)
conform to current POSIX and X/Open standards. Fixes PR/33676.
- struct timeval time is gone
time.tv_sec -> time_second
- struct timeval mono_time is gone
mono_time.tv_sec -> time_uptime
- access to time via
{get,}{micro,nano,bin}time()
get* versions are fast but less precise
- support NTP nanokernel implementation (NTP API 4)
