logging.
r155957:
Use the recently added msleep_spin() function to simplify the
callout_drain() logic. We no longer need a separate non-spin mutex to
do sleep/wakeup with, instead we can now just use the one spin mutex
to manage all the callout functionality.
r163246:
Improve ktr(4) logging for callout(9) subsystem. Log all inserts and
removals, including failures, into the callwheel.
r171053:
Fix an old standing LOR between callout_lock and sleepqueues chain
(which could lead to a deadlock).
- sleepq_set_timeout acquires callout_lock (via callout_reset()) only
with sleepq chain lock held
- msleep_spin in _callout_stop_safe lock the sleepqueue chain with
callout_lock held
In order to solve this don't use msleep_spin in _callout_stop_safe()
but use directly sleepqueues as inline msleep_spin code. Rearrange the
wakeup path in order to have it consistent too.
r172025:
Close a race that snuck in with the recent changes to fix a LOR
between the callout_lock spin lock and the sleepqueue spin locks.
In the fix, callout_drain() has to drop the callout_lock so it can
acquire the sleepqueue lock. The state of the callout can change
while the callout_lock is held however (for example, it can be
rescheduled via callout_reset()). The previous code assumed that the
only state change that could happen is that the callout could finish
executing. This change alters callout_drain() to effectively restart
and recheck everything after it acquires the sleepqueue lock thus
handling all the possible states that the callout could be in after
any changes while callout_lock was dropped.
After the commit of SVN rev 180236, wilko@ noticed that the approach
doesn't work on the Alpha platform: machine/elf.h doesn't include
sys/elf32.h there.

- Increase the size of the salt in pw(8) from 8 to 32 (same as in pam_unix(8)).
This makes blowfish password hashes look normal when set using
pw(8)/adduser(8). [1]

Add driver support for PCIe adapters based on JMicron JMC250
gigabit ethernet and JMC260 fast ethernet controllers. ATM jme(4)
supports all hardware features except RSS and multiple Tx/Rx queue.
In these days most ethernet controller vendors take a ply of
concealing hardware detailes from open source developers. As
contrasted with these vendors JMicron provided all necessary
information needed to write a stable driver during driver writing
and answered many questions I had. They even helped fixing driver
bugs with protocol analyzer. Many thanks to JMicron for their
support of FreeBSD.

Add -m option to cron(8), overriding default mail recipient for cron
mails, unless explicitly provided by MAILTO= line in crontab. This
feature can be useful in massive hosting environment, where most users
do not care about autogenerated mails.
Setting recipient to null string disables default mails at all.

- Fix spelling and style.
- Use __FBSDID.
- Merge macros depending on the flags being preserved between calls
into a single "__asm"-statement as GCC doesn't guarantee their
consecutive output even when using consecutive "__asm __volatile"-
statement for them. Remove the otherwise unnecessary "__volatile". [1]
- The inline assembler instructions used here alter the condition
codes so add them to the clobber list accordingly.
- The inline assembler instructions used here uses output operands
before all input operands are consumed so add appropriate modifiers.

In case of interface initialization failure remove struct in_ifaddr* from
in_ifaddrhashtbl in in_ifinit because error handler in in_control removes
entries only for AF_INET addresses. If in_ifinit is called for the cloned
inteface that has just been created its address family is not AF_INET and
therefor LIST_REMOVE is not called for respective LIST_INSERT_HEAD and
freed entries remain in in_ifaddrhashtbl and lead to memory corruption.
