2006-03-29[PATCH] ixp2000: fix gcc4 breakageLennert Buytenhek1-4/+1
gcc4 doesn't like us declaring a static function inside another function. We can do away with this construct altogether and use BUILD_BUG_ON() instead (idea from Andi Kleen.) Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-03-29[PATCH] Janitor: drivers/net/pcnet32: fix incorrect commentsLinas Vepstas1-2/+2
The comments concerning how the pcnet32 ethernet device driver selects the MAC addr to use are incorrect. A recent patch (in the last 3 months) changed how the code worked, but did not change the comments. Side comment: the new behaviour is good; I've got a pcnet32 card which powers up with garbage in the CSR's, and a good MAC addr in the PROM.

2006-03-29b44: fix force mac address before ifconfig upGary Zambrano1-0/+5
Initializing the b44 MAC & PCI functional blocks in the controller must occur inside init_one(). This will allow access to the MAC registers. The controller was being powered up in b44_open() which would not allow access to the registers before ifconfig was up. Philip Kohlbecher found this bug.

2006-03-29IB/mthca: Fix check of size in SRQ creationJack Morgenstein1-1/+1
The previous patch for Tavor broke MemFree logic. The driver should perform limit check only for Tavor. For MemFree, the check is incorrect, since ds (WQE stride) is always a power-of-2 (although the max_desc_size may not be). In Tavor, however, WQE stride and desc_size are the same, and are not necessarily power-of-2. The check was really for the WQE stride (and it Tavor, we use max_desc_size for the stride).

2006-03-28[PATCH] send_sigqueue: simplify and fix the raceOleg Nesterov1-37/+4
send_sigqueue() checks PF_EXITING, then locks p->sighand->siglock. This is unsafe: 'p' can exit in between and set ->sighand = NULL. The race is theoretical, the window is tiny and irqs are disabled by the caller, so I don't think we need the fix for -stable tree. Convert send_sigqueue() to use lock_task_sighand() helper. Also, delete 'p->flags & PF_EXITING' re-check, it is unneeded and the comment is wrong.

2006-03-28[PATCH] simplify do_signal_stop()Oleg Nesterov1-24/+8
do_signal_stop() considers 'thread_group_empty()' as a special case. This was needed to avoid taking tasklist_lock. Since this lock is unneeded any longer, we can remove this special case and simplify the code even more. Also, before this patch, finish_stop() was called with stop_count == -1 for 'thread_group_empty()' case. This is not strictly wrong, but confusing and unneeded.

This also means that SIGSTOP or sig_kernel_coredump() signal can't be delivered to pgrp/session reliably. With this patch copy_process() returns -ERESTARTNOINTR when it detects a pending signal, fork() will be restarted transparently after handling the signals.

2006-03-28[PATCH] pids: kill PIDTYPE_TGIDOleg Nesterov4-14/+12
This patch kills PIDTYPE_TGID pid_type thus saving one hash table in kernel/pid.c and speeding up subthreads create/destroy a bit. It is also a preparation for the further tref/pids rework. This patch adds 'struct list_head thread_group' to 'struct task_struct' instead. We don't detach group leader from PIDTYPE_PID namespace until another thread inherits it's ->pid == ->tgid, so we are safe wrt premature free_pidmap(->tgid) call. Currently there are no users of find_task_by_pid_type(PIDTYPE_TGID). Should the need arise, we can use find_task_by_pid()->group_leader.

2006-03-28[PATCH] do __unhash_process() under ->siglockOleg Nesterov1-2/+2
This patch moves __unhash_process() call from realease_task() to __exit_signal(), so __detach_pid() is called with ->siglock held. This means we don't need tasklist_lock to iterate over thread group anymore: copy_process() was already changed to do attach_pid() under ->siglock. Eric's "pidhash-kill-switch_exec_pids.patch" from -mm changed de_thread() so it doesn't touch PIDTYPE_TGID. NOTE: de_thread() still needs some attention. It still changes task->pid lockless.

2006-03-28[PATCH] copy_process: cleanup bad_fork_cleanup_signalOleg Nesterov4-20/+21
__exit_signal() does important cleanups atomically under ->siglock. It is also called from copy_process's error path. This is not good, for example we can't move __unhash_process() under ->siglock for that reason. We should not mix these 2 paths, just look at ugly 'if (p->sighand)' under 'bad_fork_cleanup_sighand:' label. For copy_process() case it is sufficient to just backout copy_signal(), nothing more. Again, nobody can see this task yet. For CLONE_THREAD case we just decrement signal->count, otherwise nobody can see this ->signal and we can free it lockless. This patch assumes it is safe to do exit_thread_group_keys() without tasklist_lock. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Cc: "Eric W.

The only caller of exit_sighand(tsk) is copy_process's error path. We can call __exit_sighand() directly and kill exit_sighand(). This 'tsk' was not yet registered in pid_hash[] or init_task.tasks, it has no external references, nobody can see it, and IF (clone_flags & CLONE_SIGHAND) At least 'current' has a reference to ->sighand, this means atomic_dec_and_test(sighand->count) can't be true.
