- Enable debug messages but set log level to be quiet. Provide a
system (hw.iscsi.debug) to set the log level at run time.
- Replace old tsleep/wakeup synchronization with mutexes and condvars.
- Defer actions from callouts (basically timeouts) to the cleanup thread.
- Protect lists and unique ids with mutexes. protect connection usecount
by using atomic operations.
- Assert kernel lock when calling into scsipi and network code.
- Use this to make send/receive/cleanup threads MPSAFE.
- Fix handling of out-of-CCB/out-of-PDU conditions against the scsipi layer.
- Bump number of PDUs to 128 to avoid virtually all out-of-PDU conditions
- Make use of softc structure for attach/detach operations.
- Track open file handles to prevent detach when busy.
- Move some global variables to make them static.
- Fix 'Overlapping Commands Attempted' error by marking commands as
simply ordered (ATTR_SIMPLE) like FreeBSD.
- debug log is now using syslog
- seperate options for log level and foreground mode
- writes a pidfile so that /etc/rc.d/iscsid works
Now links with libutil for pidfile(), the functions login() and logout()
needed to be renamed to avoid a conflict.
- drops the nothreads option
- handles signals to shut down gracefully
- the driver may also shut down the daemon when it terminates
Currently this cannot work as the driver can only terminate when
the daemon has closed the driver file handle.
fresh install in a dual boot scenario to fail. This is because fstab will be
referencing wd(4) and the kernel expecting dk(4).
Closes PR port-macppc/51160
it's not a 16750 either. Like the 16750 it has the IIR_BUSY interrupt,
which is triggered when writing to LCR while the chip
can't accept it. But unlike the 16750, it has a specific register,
HALT, to allow writing to the LCR and divisor registers, and then
commit the changes.
Tested on an A20 SoC, changing the baud rate while keeping the
tty device open and incoming data.
amd64 and i386.
The fillkpt loop is equivalent to the following:
do {
/* fill in the slot */
/* increment %ebx to the next slot */
/* increment %eax to the next pa */
} while (%ecx > 0)
The issue here is that if %ecx = 0 (i.e., the chunk we are trying to
map is zero-sized), there is still one entry created in the page table.
The kernel expects the va<->pa translation to be linear in low memory.
If there is a zero-sized chunk, the dead entry creates a +4096 offset in
the virtual space, with two consecutive entries that point to the same
physical address. In other words, the mappings are not linear anymore,
which causes the kernel to die.
Before my recent changes, there were only two big chunks that were
mapped, and neither of these could be zero-sized. Now, with multiple,
fine-grained chunks, it is possible that the [SYMS]+[PRELOADED_MODULES]
chunk could be zero-sized.
[PRELOADED_MODULES] is almost never here, and [SYMS] is always here on
default kernels. Except for floppies, where the bootloader does not load
[SYMS].
Should fix PR 51148.
as documented in sysctl(7):
0 - ptrace does not affect mprotect
1 - (default) mprotect is disabled for processes that start executing from
the debugger (being traced)
2 - mprotect restrictions are relaxed for traced processes
