- to reduce cpu consumption for a long queue, maintain the sorted lists of
buffers with rbtree instead of TAILQ. i vaguely remember that the problem
pointed out by someone on a public mailing list while ago. sorry, i can't
remember who and where.
- add some #ifdef'ed out experimental code.
- bump kernel version for struct buf change.
(exec_free_emul_arg) to call the hook and then clear the ep_emul_arg
and ep_emul_arg_free members in the exec_package.
Change users/accessors to use these routines.
Approved by releng.
1) Move core entropy-pool code and source/sink/sample management code
to sys/kern from sys/dev.
2) Remove use of NRND as test for presence of entropy-pool code throughout
source tree.
3) Remove use of RND_ENABLED in device drivers as microoptimization to
avoid expensive operations on disabled entropy sources; make the
rnd_add calls do this directly so all callers benefit.
4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might
have lead to slight entropy overestimation for some sources.
5) Add new source types for environmental sensors, power sensors, VM
system events, and skew between clocks, with a sample implementation
for each.
ok releng to go in before the branch due to the difficulty of later
pullup (widespread #ifdef removal and moved files). Tested with release
builds on amd64 and evbarm and live testing on amd64.
unsigned. They are signed. (While unsigned might have been a better
choice, it doesn't really matter and the majority of preexisting uses
were signed. And consistency is good.)
- struct vfs_quotactl_args -> struct quotactl_args
- add sys/stdint.h to sys/quotactl.h for clean userland build
- install sys/quotactl.h in /usr/include
- update set lists for same
- add new marshalling code in libquota
- add new unmarshalling code in vfs_syscalls.c
- discard proplib interpreter code in vfs_quotactl.c
- add dispatching code for the 14 quotactl ops in vfs_quotactl.c
- mark the proplib quotactl syscall obsolete
- add a new syscall number for the new quotactl syscall
- change the name of the syscall to __quotactl()
- remove the decl of the old quotactl from quota/quotaprop.h
- add a decl of the new quotactl to sys/quotactl.h
- update the libc build
- update ktruss
- remove proplib marshalling code from libquota
- update copy of syscall table in gdb ppc sources
- hack rumphijack to accomodate new quotactl name (as I recall,
pooka wanted such a name change to simplify something, but I
don't really see what/how)
This change appears to require a kernel version bump for rumpish
reasons.
aligned to (ALIGNBYTES+1). this ensures that the memory that malloc(9)
returns is correctly aligned for the platform. this change has an
effect on hppa, ia64, sparc and sparc64.
necessary on sparc for 8-byte load/store instructions. with this my
SS20 boots multiuser again.
logical order (as opposed to the previous order, which accumulated
arbitrarily), remove the separate codes for argument encoding as
there's now a 1-1 mapping between ops and argument substructures,
and assert in VFS_QUOTACTL() itself that the op in the args structure
matches the op passed directly.
This change requires a kernel version bump.
